2Dear Owner, We would like to thank you for your purchase of a Porsche Sports car. Judging by the car you have chosen, you are a mo-torist of a special breed, and you are probably no novice when it comes to automobiles. Remember however, as with any vehicle, you should take time to familiarize yourself with your Porsche and its performance characteristics. Al-ways drive within your own unique capabilities as a driver and your level of experience with your Porsche. Ensure that anyone else driving your Porsche does the same. To prevent or minimize in-jury, always use your safety belts. Never consume alcohol or drugs before or during the operation of your vehicle. This Owner’s Manual contains a host of useful in-formation. Please take the time to read this manu-al before you drive your new Porsche. Become fa-miliar with the operation of your Porsche car for maximum safety and operating pleasure. The bet-ter you know your Porsche, the more pleasure you will experience driving your new car.Always keep your Owner’s Manual in the car, and give it to the new owner if you ever sell your Porsche. A separate Maintenance Booklet explains how you can keep your Porsche in top driving condition by having it serviced regularly. A separate Warranty and Customer Informa-tion Booklet contains detailed information about the warranties covering your Porsche. For U.S. only:If you believe that your vehicle has a fault which could cause a crash, injury or death, you should immediately inform the National Highway Traffic Safety Administration (NHTSA) in addition to notifying Porsche Cars North America, Inc. (Porsche Cars N.A.). If NHTSA receives similar complaints, it may open an investigation, and if it finds that a safety prob-lem exists in a group of vehicles, it may order a re-call and remedy campaign. However, NHTSA can-not become involved in individual problems be-tween you and your dealer, or Porsche Cars N.A.. To contact NHTSA, you may either call the Auto Safety Hotline toll-free at 1-(800)-424-9393 (or 366-0123 in Washington, D.C. area) or write to: NHTSA, U.S. Department of Transportation, Washington, D.C. 20590. You can also obtain oth-er information about motor vehicle safety from the Hotline. Your car has thousands of parts and components which have been designed and manufactured in accordance with Porsche’s high standards of engi-neering quality and safety. Any alteration of the vehicle may negate or interfere with those safety features built into the vehicle. Your Porsche is intended to be used in a safe man-ner obeying the local laws and in the light of driv-ing conditions faced by you, and in accordance with the instructions provided in this Owner’s Man-ual. Do not misuse your Porsche by ignoring those laws and driving conditions, or by ignoring the instructions in this manual. Any alteration or misuse of the vehicle can lead to accidents and severe or fatal personal injuries. The fitting of racing tires (e.g. slicks) for sporting events is not approved by Porsche. Very high cor-nering speeds can be achieved with racing tires. However, the resulting transverse acceleration values would jeopardize the adequate supply of oil to the engine.Porsche therefore will not accept any warranty or accept any liability for damage occurring as a re-sult of non-compliance with this provision.
3Regularly check your vehicle for signs of damage. Damaged or missing aerodynamic compo-nents such as spoilers or underside panels affect the driving behavior and therefore must be replaced immediately. Your car may have all or some of the components described in this manual. Should you have difficulty understanding any of the explanations of features or equipment installed in your vehicle, contact your authorized Porsche dealer. He/She will be glad to assist you. Also check with your dealer on other available options or equipment. Throughout this booklet, left is designated as the driver’s side of the vehicle, and right as the pas-senger’s side of the vehicle. Text, illustrations and specifications in this manual are based on the information available at the time of printing. It has always been Porsche’s policy to continuous-ly improve its products. Porsche, therefore, re-serves the right to make changes in design and specification, and to make additions or improvements in its product without incurring any obligation to install them on products previously manufactured. We wish you many miles of safe and pleasurable driving in your Porsche. ImportantFor your own protection and longer service life of your car, please heed all operating instructions and special warnings. These special warnings use the safety alert symbol, followed by the words Danger, Warning and Caution. These special warnings contain important messages regarding your safety and/or the potential for damage to your Porsche. Ignoring them could result in seri-ous mechanical failure or even physical injury. fDo not alter your Porsche. Any alteration could create dangerous conditions or defeat safety engineering features built into your car. fDo not misuse your Porsche. Use it safely, and consistently with the law, according to the driv-ing conditions, and the instructions in this man-ual. Alteration or misuse of your Porsche could cause accidents and severe or fatal personal injuries. Note to owners In Canada, this manual is also available in French.

4Fuel Quality Your engine is designed to provide optimum performance and fuel economy using unleaded premium fuel with an octane rating of 98 RON (93 CLC or AKI). Porsche therefore recommends the use of these fuels in your vehicle. Porsche also recognizes that these fuels may not always be available. Be assured that your vehicle will operate properly on unleaded premium fuels with octane numbers of at least 95 RON (90 CLC or AKI), since the engine’s ”Electronic Oktane™ knock control“ will adapt the ignition timing, if necessary.Fuels containing alcohol and ether Some areas of the U.S. require oxygenated fuels during certain portions of the year. Oxygenated fuels are fuels which contain alcohols (such as methanol or ethanol) or ether (such as MTBE). Under normal conditions, the amount of these compounds in the fuel will not affect driveability. You may use oxygenated fuels in your Porsche, provided the octane requirements for your vehicle are met. We recommend, however, to change to a different fuel or station if any of the following problems occur with your vehicle:– Deterioration of driveability and performance. – Substantially reduced fuel economy. – Vapor lock and non-start problems, especially at high altitude or at high temperature. – Engine malfunction or stalling.Fuels containing MMT Some North American fuels contain an octane enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT).If such fuels are used, your emission control system performance may be negatively affected. The check engine warning lights on your instrument panel may turn on. If this occurs, Porsche recommends you stop using fuels containing MMT.
5Tire Pressures for Cold Tires Summer tires and snow tiresThese tire pressures are valid only for Porsche approved tires. For replacement tires it is imperative that you consult the Technical Data and Tires, Wheelssections of this manual and follow the recommendations contained therein. 18 inch wheels front 36 psi (2.5 bar)rear 44 psi (3.0 bar)19 inch wheels, partially loaded front 33 psi (2.3 bar)(up to 2 persons without luggage) rear 39 psi (2.7 bar)19 inch wheels, fully loaded front 36 psi (2.5 bar)(more than 2 persons with luggage) rear 44 psi (3.0 bar)
6Porsche and the Environment Environmental guidelinesWe develop and produce exclusive sports cars with advanced environmental and safety technolo-gy and a great ability to fascinate. Our environmental policy is based on the following principles:– The maximum possible use of environmentaland safety technology that is economically jus-tifiable. – Economical usage of energy and resources. – Involvement of our business partners and con-tractors in our efforts to protect the environ-ment. – Open dialogue with all social groups. California Proposition 65 Warning Warning!Engine exhaust, some of its constituents, and cer-tain vehicle components contain or emit chemi-cals known to the State of California to cause can-cer and birth defects or other reproductive harm.In addition, certain fluids contained in vehicles and certain products of component wear contain or emit chemicals known to the State of California to cause cancer and birth defects or other reproduc-tive harm. ProductionWhether in production or repair, Porsche always relies on environmentally friendly technology.An example of this is the water-based paint used in our painting installation.Water-base paints and new painting methods re-duce solvent emissions by 70 per cent.And the water used in the painting installation is re-circulated. Waste water leaves the Porsche facto-ry only after being appropriately treated. A waste-management system has been introduced to reduce the amount of waste while simultaneous-ly increasing the recycling rate.
7Environmentally friendly vehiclesModern environmental technology ensures compli-ance with all emission laws applicable worldwide. These have the following advantages:– Rapid operational readiness of the catalytic converters ensures low emissions, even in short-trip operation. – Reliable operation and good emission controlover a long useful life. fPlease refer to the chapter “FUEL ECONOMY” on page 163. Recycling – for a Porsche, this is virtually an academic question More than two-thirds of all Porsches ever built are still running. Just in case recycling is ever necessary, we take the following precautionary measures: – Identification of all materials. – Use of recyclable materials. – Reusable components designed for simple removal. – These reasons result in a further increase in the recycling rate which is currently 80 per cent. Emission control is built inInnovative engine technology combines high en-gine performance and environmental compati-bility. The engine diagnosis system electronically moni-tors the components and systems that affect ex-haust gases. This continuous monitoring and fault storage ena-bles swift, reliable diagnosis and fault detection. Any fault messages are indicated to the driver by the ”Check Engine“ warning light and the on-board computer. fPlease refer to the chapter “WARNINGS ON THE INSTRUMENT PANEL AND THE ON-BOARD COMPUTER” on page 102.
8Porsche Ceramic Composite Brake (PCCB)The high-performance brake system is designed for optimal braking effect at all speeds and temperatures. Certain speeds, braking forces and ambient conditions (such as temperature and humidity) therefore might cause brake noises. Wear on the diffrent components and braking system, such as brake pads and brake discs, depends to a great extent on the individual driving style and the conditions of use and therefore cannot be expressed in actual miles on the road. The values communicated by Porsche are based on normal operation adapted to traffic. Wear increases considerably when the vehicle is driven on race tracks or through an aggressive driving style.fPlease consult an authorized Porsche dealer about the current guidelines in effect before such use of your vehicle.Setting and operating vehicle components when driving Warning!There is a danger of accident if you set or op-erate the on-board computer, radio, naviga-tion system, telephone, convertible top or other equipment when driving.This could distract you from the traffic and cause you to lose control of the vehicle re-sulting in serious personal injury or death. fOperate the components while driving only if the traffic situation allows you to do so safely. fCarry out any complicated operating or setting procedures only with the vehicle stationary. Portable Fuel Containers Danger!Portable fuel containers, full or partially empty, may leak, causing an explosion, or result in fire in case of an accident. fNever carry additional fuel in portable contain-ers in your vehicle.
9Engine Exhaust Danger!Engine exhaust is dangerous if inhaled.Engine exhaust fumes have many compo-nents which you can smell. They also contain carbon monoxide (CO), which is a colorless and odorless gas.Carbon monoxide can cause unconscious-ness and even death if inhaled. fNever start or let the engine run in an en-closed, unventilated area.It is not recommended to sit in your car for pro-longed periods with the engine on and the car not moving.Ground ClearancePlease bear in mind the limited ground clearance of your car on uneven surfaces, when parking (curbs), on ramps, lifting platforms, etc.

14 Controls, InstrumentsDear Porsche Owner A lot has gone into the manufacture of your Porsche, including advanced engineering, rigid quality control and demanding inspections. These engineering and safety features will be enhanced by you... the safe driver... – who knows his car and all controls, – who maintains the vehicle properly, – who uses driving skills wisely and always drives within her/his own capabilities and the level of familiarity with the vehicle. You will find helpful hints in this manual on how to perform most of the checks listed on the following pages. If in doubt, have these checks performed by your authorized Porsche dealer. Before driving off... Check the following items first fTurn the engine off before you attempt any checks or repairs on the vehicle. fBe sure the tires are inflated correctly. Check tires for damage and tire wear. fSee that wheel bolts are properly tightened and not loose or missing. fCheck engine oil level, add if necessary. Make it a habit to have engine oil checked with every fuel filling. fCheck all fluid levels such as windshield washer and brake fluid levels. fBe sure the vehicle battery is well charged and cranks the engine properly. fCheck all doors and lids for proper operation and latch them properly. fCheck, and if necessary replace worn or cracked wiper blades. fSee that all windows are clear and unob-structed. fCheck air intake slots and area between lug-gage compartment lid and windshield are free of snow and ice, so the heater and the wind-shield wipers work properly. fIf a child will be riding in the vehicle, check child seat/child seat restraint system to ensure that restraints are properly adjusted. fCheck all exterior and interior lights for opera-tion and that the lenses are clean. fCheck the headlights for proper aim, and if necessary, have them adjusted. fCheck under the vehicle for leaks. fBe sure all luggage is stowed securely. Emergency equipment It is good practice to carry emergency equipment in your vehicle. Some of the items you should have are: window scraper, snow brush, container or bag of sand or salt, emergency light, small shovel, first-aid kit, etc.
Controls, Instruments 15In the driver’s seat... fCheck operation of the horn. fPosition seat for easy reach of foot pedals and controls.To reduce the possibility of injury from the airbag deployment, you should always sit back as far from the steering wheel as is practical, while still maintaining full vehicle control. fAdjust the inside and outside rear view mirrors. fBuckle your safety belts. fCheck operation of the foot and parking brake. fCheck all warning and indicator lights with ignition on and engine not running. fStart engine and check all warning displays for warning symbols. fNever leave an idling car unattended. fLock doors from inside, especially with chil-dren in the car to prevent inadvertent opening of doors from inside or outside.Drive with doors locked. On the road... fNever drive after you have consumed alcohol or drugs. fAlways have your safety belt fastened. fAlways drive defensively. Expect the unexpected. fUse signals to indicate turns and lane changes. fTurn on headlights at dusk or when the driving conditions warrant it. fAlways keep a safe distance from the vehicle in front of you, depending on traffic, road and weather conditions. fReduce speed at night and during inclement weather.Driving in wet weather requires caution and re-duced speeds, particularly on roads with standing water, as the handling characteristics of the vehicle may be impaired due to hydro-planing of the tires. fAlways observe speed limits and obey road signs and traffic laws. fWhen tired, get well off the road, stop and take a rest. Turn the engine off. Do not sit in the ve-hicle with engine idling. Please observe the chapter “ENGINE EX-HAUST” on Page 9.fWhen parked, always set the parking brake. Move the Tiptronic selector lever to ”P“ or the gearshift lever to reverse or first gear. On hills also turn the front wheels toward the curb. fWhen emergency repairs become necessary, move the vehicle well off the road. Turn on the emergency flasher and use other warning de-vices to alert other motorists. Do not park or operate the vehicle in areas where the hot ex-haust system may come in contact with dry grass, brush, fuel spill or other flammable ma-terial. fMake it a habit to have the engine oil checked before every fuel filling.
16 Controls, InstrumentsBreak in hints for the first 2,000 miles/3,000 kilometers The following tips will be helpful in obtaining opti-mum performance from your new Porsche. Despite the most modern, high-precision manufac-turing methods, it cannot be completely avoided that the moving parts have to wear in with each other. This wearing-in occurs mainly in the first 2,000 miles/3,000 km. Therefore: fPreferably take longer trips. fAvoid frequent cold starts with short-distance driving whenever possible. fAvoid full throttle starts and abrupt stops. fDo not exceed maximum engine speed of 4,200 rpm (revolutions per minute). fDo not run a cold engine at high rpm either in Neutral or in gear. fDo not let the engine labor, especially when driving uphill. Shift to the next lower gear in time (use the most favorable rpm range). fNever lug the engine in high gear at low speeds. This rule applies at all times, not just during the break-in period. fDo not participate in motor racing events, sports driving schools, etc. during the first 2,000 miles/3,000 kilometers.There may be a slight stiffness in the steering, gear-shifting or other controls during the break-in period which will gradually disappear. Break in brake pads and brake discsNew brake pads and discs have to be “broken in”, and therefore only attain optimal friction when the car has covered several hundred miles or km.The slightly reduced braking ability must be com-pensated for by pressing the brake pedal harder. This also applies whenever the brake pads and brake discs are replaced. New tires New tires do not have maximum traction. They tend to be slippery. fBreak in new tires by driving at moderate speeds during the first 60 to 120 miles/100 to 200 km. Longer braking distances must be an-ticipated. Engine oil consumption During the break-in period oil consumption may be higher than normal. As always, the rate of oil consumption depends on the quality and viscosity of oil, the speed at which the engine is operated, the climate and road con-ditions, as well as the amount of dilution and oxi-dation of the lubricant. fMake a habit of checking engine oil with every fuel filling, add if necessary.

18 Controls, InstrumentsNever invite car theft! An unlocked car with the key in the ignition lock invites car theft. A steering wheel lock and a gong alarm are standard equipment in your Porsche. The gong alarm will sound if you open the driver’s door while the key is still in the ignition lock. It is your reminder to pull the key out of the ignition lock and to lock the doors. Warning!Any uncontrolled movement of the vehicle may result in serious personal injury and property damage.Never leave your vehicle unattended with the key in the ignition lock, especially if children and/or pets are left unattended in the vehi-cle. They can operate power windows and other controls. If the engine is left running, they may accidentally engage the shift lever.fAlways remove the ignition key. fAlways set the parking brake. fLock the doors with the remote control. Warning!Risk of a serious accident. The steering column will lock when you re-move the key while you are driving or as the car is rolling to a stop. You will not be able to steer the car. fNever remove the key from the steering lock while you are driving. To protect your vehicle and your possessions from theft, you should always proceed as follows when leaving your vehicle: fClose windows.fClose lifting/sliding rooffRemove ignition key. fEngage steering lock. fLock glove compartment. fRemove valuables (e.g. car documents, tele-phone, house keys) from the car. fLock doors.
Controls, Instruments 19Keys fPlease observe the chapter “ALARM SYSTEM, PASSENGER COMPARTMENT MONITORING” on Page 26.fPlease observe the chapter “CENTRAL LO-CKING” on Page 22.Two main keys and one spare key are supplied with your Porsche. These keys operate all the locks on your vehicle. fBe careful with your car keys: do not part with them except under exceptional circumstances. fTo avoid battery run-down, always remove the ignition key from the ignition lock. Replacement keys Replacement car keys can be obtained only from your authorized Porsche dealer, and this can sometimes be very time-consuming.You should therefore always keep the spare key on your person. Keep it in a safe place (e.g. wallet), but under no circumstances in or on the vehicle. The key codes of new keys have to be “reported” to the car control unit by your authorized Porsche dealer. The key grip of the spare key can be exchanged for a main-key grip. Disabling key codes If a key is lost, the key codes can be disabled by an authorized Porsche dealer.All the remaining car keys are required for this pur-pose.Disabling the code ensures that the car can be started only using authorized keys. NotefPlease note that the other locks can still be opened with the disabled key. Immobilizer There is a transponder (an electronic component) in the key grip, containing a stored code. When the ignition is switched on, the ignition lock checks the code. The immobilizer can be deactivated and the en-gine started only using an authorized ignition key.Switching off the immobilizerfInsert the ignition key into the ignition lock.If the ignition is left on for more than 2 minutes without the engine being started, the immobilizer is reactivated.fIf this happens, turn the ignition key back to the 3 position before starting the engine.Switching on the immobilizerfRemove ignition key.Security Wheel Bolts fIf wheels have to be removed during a work-shop visit, do not forget to hand over the sock-et for the security wheel bolts along with the car key.

50 Controls, InstrumentsAirbag SystemsThe airbags in combination with the safety belts make up a safety system which offers the driver and the passenger the greatest known protection from injuries in case of accident. Even though your vehicle is equipped with airbags, the safety belts are your primary protection and must be worn at all times.The airbags can only help protect you where the impact is of sufficient severity and from a speci-fied direction.Therefore, all persons within the vehicle must always wear safety belts (in many states, state law requires the use of safety belts).fPlease observe the chapter “SAFETY BELTS” on Page 42.The front airbags are located behind the padded steering wheel panel on the driver’s side and on the passenger’s side in the dashboard.The side airbags are installed in the side of the seat backrests.The head airbags are installed in the door linings.Function Depending on the force and angle of impact, the corresponding airbags can be triggered.The inflation process generates the amount of gas required to fill the airbags at the necessary pres-sure in fractions of a second. Because of the pos-sibility of injuries from airbag deployment, airbags are designed to deploy only when occupants can receive substantial additional injuries from their deployment.Airbags protect the face and upper body, while simultaneously damping the motion of the driver and passenger in the impact direction in the event of a frontal impact or side impact. Your vehicle is equipped with a crash sensing and diagnostic module. This module will record the use of the safety belt restraint system by the driv-er and front passenger when the side airbags and head airbags are inflated. Danger!To provide optimal occupant protection, air-bags must inflate at very high speed. If you are not wearing your safety belt or are too close to the airbag when its deployed, in-flating airbags can result in serious personal injury or death. fMake sure there are no people, animals or ob-jects between the driver or passenger and the area into which the airbag inflates. fSit back as far from the dashboard or steering wheel as is practical, while still maintaining full vehicle control. fDo not lean against the inside of the doors. fAlways leave feet in the footwell when driving. Do not put feet on the dashboard or the seat cushion.fAlways hold the steering wheel by the outer rim.Never rest your hands on the airbag panel. fNever transport heavy or sharp objects on or in front of the passenger seat. fAlways keep the lid of the door storage com-partment closed. Objects must not protrude out of the door storage compartment. fGive your passenger all of the information in this chapter. fNo changes must be made to the wiring or components of the airbag system.
Controls, Instruments 51fDo not add any additional coverings or stickers to the steering wheel or in the area of the pas-senger airbag, side airbags and head airbags. Doing so may adversely affect the functioning of the airbag system or cause harm to the oc-cupants if the airbag system should deploy. fDo not undertake any wiring for electrical ac-cessory equipment in the vicinity of the airbag wiring harnesses. Doing so may disable the airbag system or cause inflation. fIf the warning light comes on, the airbag sys-tem should be repaired immediately by your authorized Porsche dealer. NoteAirbag components (e.g. steering wheel, door trim, seats) may be disassembled only by an au-thorized Porsche dealer. When disposing of a used airbag unit, our safety instructions must be followed. These instructions can be obtained at any authorized Porsche dealer. Faults are indicated by a warning light in the instru-ment panel and a message on the on-board com-puter. fIn the following cases you should immedi-ately consult an authorized Porsche deal-er in order to assure the airbag system is functioning properly:– If the warning light does not light up when the ignition is switched on or– If the warning light does not go out once the engine is running or – If the warning light appears while driving.fPlease observe the chapter “WARNINGS ON THE INSTRUMENT PANEL AND THE ON-BOARD COMPUTER” on Page 102.Warning light “PASSENGER AIRBAG OFF”fPlease observe the chapter “SWITCHING PAS-SENGER’S AIRBAG ON AND OFF” on Page 49.Airbag maintenanceIn order to ensure long-term functioning, the air-bag system must be inspected by an authorized Porsche dealer at the intervals recommended in your Maintenance booklet.Important information If you sell your Porsche, notify the purchaser that the vehicle is equipped with airbags, and refer them to the chapter, “Airbag Systems”, in the own-er’s manual (safety and disposal rules). Further information on the airbag system can be found on labels on the sun visors, as well as on all airbag components. fFor special recommendations on the use of child restraints: Please observe the chapter “CHILD RES-TRAINT SYSTEMS” on Page 46.DisposalNon-ignited gas alternators, or whole vehicles or subassemblies with airbag units, must not be disposed of as “normal” scrap or waste or put into any other form of end storage.Your authorized Porsche dealer will be able to give you details about disposal.Warning light and warning message

Ultrasound sensors Sensors Four ultrasound sensors in the rear bumper meas-ure the distance to the closest obstacle.– Range middle sensors around 60 in./150 cm – Range outer sensors around 24 in./60 cmObstacles cannot be detected in the “blind” sen-sor area (e.g. near the ground). Note The sensors must always be kept free of dust, ice and snow in order to ensure that they are fully functional. Caution!To avoid damaging the sensors: fMaintain sufficient distance when cleaning with steam-jet units. Signal tones/function When reverse gear is selected, the parking assist-ant confirms that it is switched on by issuing a short signal tone.A detected obstacle is signalled by an intermit-tent tone. The intervals decrease as the obstacle is approached.A continuous tone sounds when the distance be-comes less than one foot. This continuous tone can stop if the obstacle is approached closer than one foot.The radio volume should not be so loud as to drown out the signal tones.
Controls, Instruments 53Limits of ultrasonic measurement The parking assistant system cannot detect:– sound-absorbing obstacles (e.g. powder snow), – sound-reflecting obstacles (e.g. glass surfac-es, flat painted surfaces) – and very thin obstacles. – Other ultrasound sources (e.g. pneumatic brakes of other vehicles, jackhammers) can in-terfere with detection of obstacles. Fault indication The parking assistant system indicates a fault in two ways:– After reverse gear has been selected, the short signal tone is followed by a continuous tone of the same pitch:This indicates that sensors are soiled or cov-ered with ice. – After reverse gear has been selected, the short signal tone is followed by a continuous tone with a much lower pitch:This indicates a general system fault. Please have the fault remedied at an authorized Porsche dealer.

A partially engaged parking brake may allow the vehicle to roll, causing serious personal injury or death to any person in its path.fEngage the parking brake fully.Releasing the parking brake fPull the lever slightly up as you depress the re-lease button, and then push the lever all the way down.
Controls, Instruments 57The warning lights in the instrument panel and on-board computer will go out after the parking brake is fully released.The warning lights are not an indicator that the parking brake is fully set; it is only intended to be a warning to release the parking brake before driving the car. Caution! A partially engaged brake will overheat the rear brakes, reduce their effectiveness and cause excessive wear. fRelease the parking brake fully. fWhen parking your car, always set the parking brake by pulling all the way up on the lever. fMove the gearshift lever to reverse or first gear. fOn hills also turn the front wheels towards the curb. Brakes fMake it a habit to check the operation of your brakes before driving.Keep in mind that the braking distance increases very rapidly as the speed increases. At 60 mph or 100 km/h, for example, it is not twice but four times longer than 30 mph or 50 km/h. Tire trac-tion is also less effective when the roads are wet or slippery. fTherefore, always maintain a safe distance from the car in front of you. Vehicles without Porsche Ceramic Compos-ite Brake (PCCB)Even though the brake discs consist of alloyed grey cast iron, they will unavoidably start to cor-rode if your car is parked for an extended period. The brakes will tend to “rub” as a result.The nature, extent and effects of corrosion de-pend on the amount of time the vehicle was parked, whether granular or liquid road salt was spread and whether grease-dissolving agents were used in car washes.If the braking comfort is noticeably impaired, we recommend having the brake system checked by experts at an authorized Porsche dealer. Brake system function Your Porsche is equipped with a power assisted hydraulic dual circuit brake system with disc brakes at the front and rear. Both circuits function independently. One brake circuit operates the front and the other operates the rear. If one brake circuit has failed, the other will still op-erate. However, you will notice an increased pedal travel when you apply the brakes.Failure of one brake circuit will cause the stopping distance to increase. Warning!Risk of an accident.In the unlikely event of hydraulic failure of one brake circuit: fPush the brake pedal down firmly and hold it in that position. A mechanical linkage activates the second cir-cuit, and you will be able to bring the vehicle to a stop. fAfter bringing your vehicle to a complete stop, avoid driving the vehicle and instead have it towed to the nearest authorized Porsche deal-er for repair. f f fParking brake warning light USAParking brake warning lightCanada
58 Controls, InstrumentsIf the warning lights in the instrument panel and on-board computer go on while driving, the brake flu-id level may be too low, or (if the brake pedal travel has increased) one of the two brake circuits may have failed. A greater braking pressure will be required, stop-ping distances will be longer and the braking be-havior will change, particularly in curves. With correctly adjusted brakes, and a correctly working brake system, the pedal travel to the point of brake actuation should be 1-3/16 in. to 1-9/16 in. or 30 to 40 mm. Whenever the brake pedal travel exceeds this dis-tance, have the brake system checked. Brake pedal Warning!Risk of an accident.Any obstruction of the brake pedal could increase the stopping distance. fAlways check the movement of the brake pedal before driving and make sure that it is not ob-structed by a floor mat or any other object. fSecure the floor mat to prevent it from sliding into positions that could interfere with the safe operation of your vehicle.Your Porsche dealer will be glad to offer you nonskid floor mats of the correct size.NoteIn case one of the two brake circuits fails, in-creased pedal travel is required to bring your vehicle to a full stop. Warning! To avoid overheating and premature wear of the brakes: fBefore descending a steep grade, reduce speed and shift the transmission into a lower gear or driving position to control speed. fDo not “ride the brakes” by resting your foot on the pedal when not intending to apply brake pressure. fDo not hold the pedal down too long or too often. This could cause the brakes to get hot and not function properly. Brake warning light USABrake warning light Canada
Controls, Instruments 59Brake booster The brake booster assists braking only when the engine is running. When the car is moving while the engine is not run-ning, or if the brake booster is defective, more pressure on the brake pedal is required to bring the car to a stop. Moisture or road salt on brakes affects braking.When the vehicle is driven on salted roads for ex-tended periods, the brakes should be washed down thoroughly about every 2 weeks. An auto-matic carwash facility cannot do this job properly. Brakes will dry after a few cautious brake applica-tions. Warning! Driving through water may reduce the trac-tion.Moisture on brakes from road water, car wash, or coating of road salt may affect braking efficiency. fCautiously apply brakes to test brakes after being exposed. Brake wear Your car has excellent brakes, but they are still subject to wear. The rate at which they wear de-pends on how the brakes are used. fHave the brake system inspected at the intervals recommended in your Maintenance Booklet. If the warning lights in the instrument panel and on-board computer stay on when the engine is run-ning or come on while driving, the brake pads are worn, excessively. fDo not continue to operate the vehicle.Have your authorized Porsche dealer inspect or replace the brake pads. Brake pads Wear on the brake pads and brake discs depends to a great extent on the driving style and the con-ditions of use and therefore cannot be expressed in actual miles on the road. The high-performance brake system is designed for optimal braking effect at all speeds and tem-peratures.Certain speeds, braking forces and ambient conditions (such as temperature and humidity) therefore might cause “brake noises”.New brake pads or linings New brake pads and brake discs have to be “bro-ken in”, and therefore only attain optimal friction when the car has covered several hundred miles or km.The slightly reduced braking ability must be com-pensated for by pressing the brake pedal harder. This also applies whenever the brake pads and brake discs are replaced.Warning light USAWarning light Canada
60 Controls, InstrumentsABS Brake System(Antilock Brake System)The ABS system represents a major contribution to the enhancement of active safety in your vehi-cle. This system prevents the wheels from locking in a panic stop on almost all road surfaces. With the ABS system in your vehicle, the following areas are enhanced: Steering, vehicle remains steerable under all braking forces when ABS is engaged. Good directional control, no swerving caused by locking of wheels under braking conditions. Shorter stopping distance, stopping distances are usually reduced because controlled braking is maximized. Prevention of wheel lock up, no brake- induced sliding and thus no localized tire wear from emer-gency braking. The crucial advantage of the ABS system over a conventional brake system is in the area of main-taining directional control and maneuverability of the car in emergency situations during normal driv-ing, including panic braking in turns. Warning! The increased control that is provided should not induce you to take greater risks with your safety. The limits dictated by the laws of physics cannot be overcome, even with ABS.The risk of accidents due to inappropriate speed cannot be reduced, even by the ABS.The driver bears the responsibility for all driving maneuvers. fAdapt your driving style to the prevailing road and weather conditions. fObey all traffic laws. Other vehicles not equipped with the ABS system may not be able to maintain control, especially on wet or poor road surfaces and thus may be more likely to impact you from behind. fTo minimize that risk, use your ABS system to increase your ability to maneuver to avoid dan-gerous situations and not merely to try to stop in the shortest distance possible.
Controls, Instruments 61Operation of the ABS systemA wheel speed sensor is mounted to each of the four wheels. If wheel lock-up of either of the front wheels or the rear wheels is sensed during brak-ing, the brake pressure is adjusted automatically until the wheel no longer slips. The brake pressure is regulated for each front wheel individually and for both of the rear wheels together. On a road surface which is slippery on only one side, the rear wheel which is braking on the slip-pery surface determines the brake pressure which will be applied equally to both rear wheels. This en-sures that directional stability is maintained. How-ever, if braking forces approach the wheel lock-up point for all wheels (panic braking) the ABS system will intervene to provide a rapid rythmic braking. The proper operation of ABS is perceived by the driver as a pulsating brake pedal in conjunction with audible noise and perhaps some vibration. fIf you experience these sensations while driv-ing or a road surface with questionable trac-tion, reduce vehicle speed appropriate for the prevailing road conditions.The functional readiness of all the main electrical components of the ABS is checked by an electronic monitoring system both before and while you drive. When the ignition is switched on the ABS warning light will light up while the system is electronically interrogated and goes out when the engine is started if the check is not yet complete. If the ABS warning lamp fails to go out, this indi-cates that ABS has been deactivated due to a fault. If the warning lights in the instrument panel and on-board computer light up while you are driv-ing, this indicates that a fault has occurred. In both cases, normal braking, as in vehicles without ABS, is still retained. The ABS system should, however, be examined at an authorized Porsche dealer immediately to pre-vent the occurrence of further faults. fIf the ABS system becomes inoperative, take your vehicle to your authorized Porsche dealer immediately. Warning! The control unit of the ABS brake system is set for standard tire size. If non-standard tires are installed, the control unit may mis-interpret the speed of the vehicle, because of the variant data it receives from the sensors on the axles.fUse only tire makes and types tested by Porsche.Warning light USAWarning light Canada
62 Controls, InstrumentsSport ModeA sportier car set-up is obtained when Sport mode is switched on. Interventions by the Porsche control systems are intentionally shifted towards greater agility and driving performance.– PASM (Porsche Active Suspension Manage-ment) is automatically changed to Sport mode, resulting in a stiffer suspension setup.– The Tiptronic S switches to a sporty gear-changing map and shortens the gear shifting periods. Gear changes take place faster.– PSM (Porsche Stability Management) control is sporty. PSM interventions take place later than in Normal mode. The driver can maneuver the vehicle with greater agility at its performance limits, without having to dispense with the assistance of PSM in emergency situations.– The electronic accelerator pedal reacts sooner, and the engine is more responsive to throttle inputs. When Sport mode is switched on, this function is activated only after the driver has floored the accelerator pedal or released it briefly.– The rpm limiter characteristic is “harder”, i.e. the engine is immediately throttled when the performance limits are reached (only in manual selection mode for vehicles with Tiptronic S).fPlease observe the appropriate chapters of this Manual.Switching Sport mode on and offfPress SPORT button in the center console.When Sport mode is switched on, the light-emitting diode in the SPORT button is lit.When Sport mode is switched on, the logo SPORT appears next to the digital speedometer.Switching Sport mode on and off simultaneously activates and deactivates the Sport mode of the PASM.After the ignition is switched off, Sport mode and PASM Sport mode are automatically reset to Normal mode.
Controls, Instruments 63Porsche Stability Management (PSM)PSM is an active control system for stabilization of the vehicle during extreme driving manoeuvres. Warning!The increased control that is provided should not induce you to take greater risks with your safety. The limits dictated by the laws of physics cannot be overcome, even with PSM.The risk of accidents due to inappropriate speed cannot be reduced, even by PSM.The driver bears the responsibility for all driving maneuvers. fAdapt your driving style to the prevailing road and weather conditions. fObey all traffic laws. Advantages of PSM – Superior traction and lane-holding ability in all driving situations – even on road surfaces with varying friction. – PSM actively stabilizes the vehicle during dy-namic driving maneuvers (e.g. rapid steering movements, during lane changes or on alter-nating curves). – Improved braking stability in curves and on dif-ferent or varying road surfaces. Readiness for operationPSM is switched on automatically every time you start the engine.FunctionSensors at the wheels, brakes, steering system and engine continuously measure:–Speed–Steering angle– Lateral acceleration– Rate of turn about the vertical axis– Brake pressurePSM uses these values to determine the direction of travel desired by the driver.PSM intervenes and corrects the course if the actual direction of motion deviates from the desired course (steering-wheel position):It brakes individual wheels as needed. In addition, the engine power may be manipulated in order to stabilize the vehicle.The events below inform the driver of PSM control operations and warn him to adapt his driving style to the road conditions:– The multi-functional information light on the instrument panel lights up.– Hydraulic noises can be heard.– The vehicle decelerates and steering-wheel forces are altered as the PSM controls the brakes.– Reduced engine power.– The brake pedal pulsates and its position is changed during braking.However, it is possible at any time to achieve full vehicle deceleration by increasing the foot pressure slightly.f f f

Controls, Instruments 135Porsche Communication Management (PCM) fRefer to the separate operating instructions before putting the PCM into operation.fPlease observe the chapter “LOAD SWITCH-OFF AFTER 2 HOURS OR 7 DAYS” on Page 209. Warning!There is a danger of accident if you set or op-erate the on-board computer, radio, navi-gation system, telephone or other equipment when driving.This could distract you from the traffic and cause you to lose control of the vehicle re-sulting in serious personal injury or death.fOperate the components while driving only if the traffic situation allows you to do so safely.fCarry out any complicated operating or setting procedures only with the vehicle stationary.The reception conditions for the radio module inte-grated in the PCM change continuously as you drive. Interference from buildings, terrain and the weather is unavoidable.FM stereo reception is particularly susceptible to varying reception conditions.Electronic accessories should only be retrofitted by a qualified specialist workshop.Accessories which have not been tested and approved by Porsche may impair radio reception.NavigationWhen put into operation for the first time, a distance of approx. 30 miles (50 km) must be driven in order for the navigation system to complete the process of fine calibration.The same applies when the tires are changed (e.g. summer/winter tires) or new tires fitted.Full location accuracy is not yet achieved during the fine-calibration process.If the vehicle has been transported (e.g. ferry, car train), the system may take a few minutes to deter-mine the current location after it has been switched on.Serious tire slip (e.g. spinning wheels on snow) may result in temporarily inaccurate navigation.When the battery has been disconnected, it may take up to 15 minutes before the navigation system is operational again.
136 Controls, InstrumentsCar Audio Operation/Tips FM reception A vehicle is not an ideal place to listen to a radio. Because the vehicle moves, reception conditions are constantly changing. Buildings, terrain, signal distance and noise from other vehicles are all working against good recep-tion. Some conditions affecting FM may appear to be problems when they are not. The following characteristics are completely nor-mal for a given reception area, and they do not in-dicate any problem with the radio itself. NoteElectronic accessories should only be installed by your authorized Porsche dealer.Equipment which has not been tested and ap-proved by Porsche may impair radio reception. Fading and drifting FM range is limited to about 25 miles (40 km), except for some high power stations. If a vehicle is moving away from the desired sta-tion’s transmitter, the signal will tend to fade and/or drift. This condition is more prevalent with FM than AM, and is often accompanied by distortion. Fading and drifting can be minimized to a certain degree by careful attention to fine tuning or selec-tion of a stronger signal. Static and fluttering When the line-of-sight link between a transmitter and vehicle is blocked by large buildings or moun-tains, the radio sound may be accompanied with static or fluttering because of the characteristic of FM. In a similar effect, a fluttering noise is sometimes heard when driving along a tree-lined road. This static and fluttering can be reduced by adjust-ing the tone control for greater bass response un-til the disturbance has passed. Multipath Because of the reflecting characteristics of FM, direct and reflected signals may reach the antenna at the same time (multipath) and cancel each other out. As a vehicle moves through these electronic dead spots, the listener may hear a momentary flutter or loss of reception. Station swapping When two FM stations are close to each other, and an electronic dead spot, such as static or multi-path area, interrupts the original signal, some-times the stronger second signal will be selected automatically until the original one returns. This swapping can also occur as you drive away from the selected station and approach another station of a stronger signal.
Controls, Instruments 137Compact disc player Caution!To avoid damage to compact disc player and discs. fUse only compact discs labeled as shown, hav-ing no dirt, damage or warpage. fNever attempt to disassemble or oil any part of the player unit. Do not insert any object other than a disc into the slot.Remember there are no user-serviceable parts inside the compact disc player. fDo not allow the disc to sustain any finger-prints, scrapes or stickers on the surfaces. This may cause poor sound quality.Hold the disc only on the edge or center hole. fWhen not in use, take the disc out of the player, put the disc back into its case and store it away from dust, heat, damp and direct sun-light.Leaving the disc on the dashboard in the sun can damage the disc. fIf the disc gets dirty, clean the disc by wiping the surfaces from the center to the outside in a radial direction with a soft cloth. Do not use a conventional record cleaner or anti-static record preservative. Disc cleaners are available in audio stores.
138 Controls, InstrumentsCar Telephone andAftermarket Alarms Important legal and safety information regarding the use of cellular telephones Some states may prohibit the use of cellular tele-phones while driving a vehicle. Check the laws and regulations on the use of cellular telephones in the areas where you drive. Danger!Risk of an accident.Severe personal injury or death can result in the event of an accident.Looking away from the road or turning your attention away from your driving can cause an accident and serious or fatal injury. When using your cellular telephone, you should al-ways: fGive full attention to your driving - pull off the road and park before making or answering a call if traffic conditions so require; and fKeep both hands on the steering wheel - use hands-free operation (if available) - pull off the road and park before using a hand-held tele-phone. It is essential to observe the instructions of the telephone manufacturer before putting the telephone into operation. Any portable telephone or radio transmitter which is used in a Porsche must be properly installed in accordance with the technical requirements of Porsche. The transmission power must not exceed 10 W.The devices must possess a type approval for your vehicle and have an “e” symbol. If you should require equipment with transmission power values greater than 10 W, please consult your authorized Porsche dealer for this purpose. He is familiar with the technical requirements for installing devices of this kind. The antennas for all radios and telephones with a transmitting antenna must be externally mounted. The improper installation of radios or telephones or use of a radio or telephone with a transmitting antenna inside the car may cause the warning lights to come on. Improper installation of such equipment can cre-ate a discharged battery or excessive current draw from added equipment. If aftermarket systems are installed by non-dealer-ship technicians or outside the selling dealer, problems may result. Installation of aftermarket equipment is not covered under the New Car War-ranty. fConsult your authorized Porsche dealer about the installation of non Porsche approved equip-ment. Reception quality The reception quality of your car telephone will change constantly when you are driving. Interfer-ence caused by buildings, landscape and weather is unavoidable. It may become particularly difficult to hear when using the hands-free function due to external noise such as engine and wind noise. Automatic car-wash fUnscrew external antennas before using an au-tomatic car-wash.

The gears are shifted automatically according to the acceler-ator position and speed.Depending on the way the vehicle is driven and on the resistance (e.g. uphill), the gear-changing points are shifted towards higher or lower engine-speed ranges.The accelerator position, driving speed, engine speed, longitudinal and lateral acceleration and the road profile all have an influence on the gear-changing characteristic.Unwanted upward shifts, e.g. before bends, are prevented by swiftly releasing the accelerator ped-al.Depending on lateral acceleration, upward chang-es on bends are not made until the engine-speed limit is reached.Under braking, and depending on the amount of deceleration, the Tiptronic changes down earlier.For subsequent cornering, the right gear is en-gaged when pressure is applied to the brakes be-fore the bend. The bend is taken in the right gear, and when you accelerate out of the bend you do not have to shift down.Sport mode switched onfPlease observe the chapter “SPORT MODE” on Page 62.If the Sport mode program is switched on, Tiptron-ic switches to a sporty gear-changing map and shortens the shifting periods. Deceleration downshifts are commenced earlier. Downshifts are already carried out in the case of slight decelerations, even at higher engine speeds.Driving offIn 2nd gear, the vehicle moves off with the throt-tle only slightly open.Move off in 1st gear with the throttle open wider or when the engine is cold.
144 Shifting GearsShifting gears on the steering wheelWith the rocker switches on the steering wheel, you can change temporarily from automatic selection mode D to manual mode M.Example:– Shifting down before bends and on entering built-up areas.– Shifting down on downward slopes (engine braking).– Shifting down for brief spurts of acceleration.– Selecting 1st gear for starting off.Manual selection mode remains engaged:– for cornering (depending on the lateral acceleration) and overrunning,– when the vehicle is stationary (e.g. at a junction).The system leaves manual selection mode:– automatically after approx. 8 seconds(unless cornering or overrunning),– if you depress the accelerator for kickdown,– after moving off.Temporary change-downConditions:Speed is higher than approx. 33 mph (54 km/h).fRapid acceleration.The Tiptronic temporarily changes to the sportiest gear-changing map, i.e. to the high-est possible gear-changing points. Correspondingly, the transmission shifts down immediately by one or two gears.Ending the function:fRelease the accelerator markedly (by approx. 25%).KickdownThe kickdown function is active in selector lever position D, even if you temporarily change to man-ual mode M using the rocker switches on the steering wheel.fFor optimum acceleration, e.g. when overtak-ing, depress the accelerator pedal beyond the full-throttle point (kickdown).The transmission shifts down depending on the speed of travel and engine speed.Upward shifts occur at the highest possible engine speeds.These gear-changing speeds remain active until the accelerator is released to approx. 80% of the full-throttle position.M - Manual selection modeThe currently selected gear is retained when you change from D to M.If you change from M to D, the gear-changing map suitable for your current driving style is selected and the appropriate gear is chosen. Warning!The kickdown function is not active in manual selection mode “M”.fTherefore shift down manually when accelerat-ing (e.g. to overtake).
Shifting Gears 145Two rocker switches in the upper steering-wheel spokes let you comfortably and reliably select the five forward speeds.Shifting upfPress upper part (+) of a rocker switch.Shifting downfPress lower part (–) of a rocker switch.Depending on driving speed and engine speed, you can shift up or down at any time.Gear changes which would exceed the upper or lower engine-speed limit will not be executed by the controller.You can change down two gears by quickly press-ing the rocker switches twice.If the engine-speed limit is reached, an automatic upward shift is performed or, just before idling speed is reached, a downward shift is performed.Select an appropriately low gear on upward and downward slopes. This will ensure optimum use of engine power and engine braking.PSM switched off and/or Sport mode switched onfPlease observe the chapter “PORSCHE STABI-LITY MANAGEMENT (PSM)” on Page 63.fPlease observe the chapter “SPORT MODE” on Page 62.If the PSM is switched off and/or Sport mode is switched on, an automatic upshift does not occur when the engine speed limit is reached.Cancelling upshift suppressionThis restriction can be cancelled for one gear change by depressing the accelerator to kick-down. If, for example, the engine speed limit is reached during overtaking and the automatic up-shift does not occur, the transmission in this case shifts up by accelerating to kickdown.fDepress the accelerator pedal beyond the full-throttle point (kickdown).Manual mode failureIf manual mode fails, the control electronics switch to automatic mode. In this event, the instru-ment cluster will display selector lever position D.fHave the fault remedied at an authorized Porsche dealer.
146 Shifting GearsSlip monitoringWhen the speeds of rotation of the front and rear axles differ by more than the maximum permissi-ble value, integrated slip monitoring changes up to the next gear.This increases driving stability on a slippery sur-face.NoteSlip monitoring is also deactivated when Porsche Stability Management (PSM) is switched off.StoppingfFor a brief stop (e.g. at a traffic light), leave the selector lever in drive position and hold the ve-hicle with the brake pedal.fFor a longer stop with the engine running, se-lect position N (neutral) and hold vehicle in po-sition with the foot brake.Select lever position D only when the foot brake pedal is depressed.fDo not hold the car on a slope using the accelerator. Use the brake pedal or the hand-brake instead.fBefore leaving the vehicle, always apply the handbrake and move the selector lever to po-sition P.ParkingfGo easy on the accelerator!fWhen parking or maneuvering in a small space, control the speed by careful use of the footbrake.Driving in winterIn wintry road conditions it is advisable to take steep inclines in manual mode. This prevents the occurrence of gear changes that could cause wheelspin.Tow-starting, towingfPlease observe the chapter “TOWING” on Page 235.Reduced driving programA transmission fault is indicated by the following symptoms:–The 4th gear display on the instrument clus-ter flashes.– The warning “Tiptronic emergency run” ap-pears on the on-board computer.– The transmission no longer shifts. Warning!Reverse gear lock monitoring is disabled in the emergency running program.Damage to the vehicle may result as well as loss of control, if the vehicle is moving for-ward fast enough to cause rear wheel lockup.fDo not shift into R while the vehicle is moving forward.Proceed as follows in the event of a transmission fault:1. Stop in a safe place.2. Move selector lever to position P, switch the ig-nition off and wait for 10 seconds.3. Start the engine.2nd gear in selector position D and reverse gear R are now available.4.

If you are not fully familiar with proper repair procedures, do not attempt the adjustments described on the following pages. This caution also applies to the entire vehicle. fOnly work on your vehicle outdoors or in a well ventilated area. fEnsure that there are no open flames in the area of your vehicle at any time when fuel fumes might be present. Be especially cau-tious of such devices such as hot water heat-ers which ignite a flame intermittently. fBefore working on any part in the engine com-partment, turn the engine off and let it cool down sufficiently. Hot engine compartment components can burn skin on contact. fBe alert and cautious around engine at all times while the engine is running.If work has to be performed with the engine running, always set the parking brake, and make sure the shift lever is in neutral position or the selector lever in position P.fIn particular, be very careful to ensure that items of clothing (ties, shirt, sleeves etc.), jewelry, long hair, hand or fingers cannot get caught in the engine-compartment blower, fan, belts or other moving parts.The radiator and radiator fans are in the front of the car.The engine-compartment blower is mounted on the engine-compartment lid.The engine-compartment blower can start or continue running as a function of temperature, even with the engine switched off.Carry out work in these areas only with the en-gine off, the ignition switched off, and exercise extreme caution.fYour Porsche is equipped with an electronic ig-nition system. When the ignition is on, high voltage is present in all wires connected with the ignition system; therefore, exercise ex-treme caution when working on any part of the engine while the ignition is on or the engine is running. fAlways support your car with safety stands if it is necessary to work under the car. fWhen working under the car without safety stands but with the wheels on the ground, make sure the car is on level ground, the wheels are blocked, and that the engine cannot be started.Remove the ignition key. fDo not smoke or allow an open flame around the battery or fuel.Keep a fire extinguisher in close reach. fIncomplete or improper servicing may cause problems in the operation of the car. If in doubt about any servicing, have it done by your authorized Porsche dealer.Improper maintenance during the warranty period may affect your Porsche warranty cov-erage. fSupplies of fluids, e.g. engine oil, brake fluid or coolant, are hazardous to your health. Keep these fluids out of children’s reach and dispose of them in accordance with the appro-priate regulations. fSome countries require additional tools and special spare parts to be carried. Please make enquiries before driving abroad. Power measurements Power measurements on dynamometers are not approved by Porsche.
Maintenance, Car Care 155Coolant LevelfPlease observe the chapter “EXERCISE EXTRE-ME CAUTION WHEN WORKING ON YOUR VE-HICLE” on Page 154.The cooling system is filled at the factory with a permanent coolant. It provides year-round protection from corrosion and freezing down to –31°F/–35°C. fOnly use antifreeze authorized by Porsche. Checking coolant level The expansion tank with its filler orifice is in the en-gine compartment. fCheck the coolant level regularly through the transparent expansion tank.When the engine is cold and the car is level the fluid level must lie between the “MIN” and “MAX” markings. Topping off coolant Warning!Danger of serious personal injury from scald-ing. Coolant is hazardous to your health, and may be fatal if swallowed. fDo not open the cap of the expansion tank while the engine is hot. fAllow the engine to cool down before opening the cap and protect your hands, arms and face from any possible escape of hot coolant. fKeep coolant out of children’s reach. fAlso, keep coolant away from your pets.They can be attracted to it should there be a spill, or to used coolant left in an open contain-er. Coolant can be deadly to pets if consumed.1. Switch engine off and let it cool.Please observe the chapter “COOLING SYS-TEM” on Page 82.2. Cover the expansion tank cap with a thick rag.Open cap slowly and carefully and allow over-pressure to escape. Then unscrew cap completely. 3.

Maintenance, Car Care 157Engine Oil Engine oil consumption It is normal for your engine to consume oil. The rate of oil consumption depends on the quality and viscosity of oil, the speed at which the engine is operated, the climate, road conditions as well as the amount of dilution and oxidation of the lubricant. If the vehicle is used for repeated short trips, and consumes a normal amount of oil, the engine oil measurement may not show any drop in the oil level at all, even after 600 miles (1,000 km) or more. This is because the oil is gradually becom-ing diluted with fuel or moisture, making it appear that the oil level has not changed. The diluting ingredients evaporate out when the vehicle is driven at high speeds, as on an express-way, making it then appear that oil is excessively consumed after driving at high speeds. If the conditions you drive your vehicle in are dusty, humid, or hot, the frequency of the oil change intervals should be greater. If the vehicle is driven at a high rate of speed, climatic conditions are warm, and the load is high, the oil should be checked more frequently, as driving conditions will determine the rate of oil consumption.– The engine in your vehicle depends on oil to lubricate and cool all of its moving parts. Therefore, the engine oil should be checked regularly and kept at the required level. – Make it a habit to have the engine oil level checked at every fuel filling. – The oil pressure warning light is not an oil level indicator. The oil pressure warning light indicates serious engine damage may be occuring when lit, if en-gine rpm is above idle speed.Engine Oil Level fPlease observe the chapter “EXERCISE EXTRE-ME CAUTION WHEN WORKING ON YOUR VE-HICLE” on Page 154.fRegularly check the oil level using the on-board computer after the vehicle is refuelled.Please observe the chapter “OIL DISPLAY AND MEASUREMENT OF THE ENGINE OIL LEVEL” on Page 98.The difference between the minimum and maxi-mum marks on the segment display is approx. 1.2 liters.Each segment of the display corresponds to ap-prox. 0.4 liter.f f f
158 Maintenance, Car CareTopping off engine oil Warning! Risk of burning from hot parts in engine com-partment. Risk of injury by rotating parts. The engine compartment blower on the en-gine compartment lid can start up even with engine off.fExercise extrem caution when working in the engine compartment.fTop off engine oil only with the engine off.Engine oil is hazardous to your health and may be fatal if swallowed. fKeep engine oil out of children’s reach.Used engine oil contains chemicals that have caused cancer in laboratory animals. fAlways protect your skin by washing thorough-ly with soap and water. 1. The on-board computer indicates how much oil must be added.2. Pull oil filler tube upwards out of its holder. 3. Unscrew cap of the oil filler opening.4. Add at most 0,5 quarts (0,5 liter) of engine oil at a time.5. Measure oil level again with the on-board computer.6. Add more engine oil if necessary.Never add more engine oil than required to reach the max. mark.7. Carefully close cap of the oil filler opening.8. Push oil filler tube into its holder until it snaps into place.
Maintenance, Car Care 159Engine Oil RecommendationRecommended oil viscosity ranges dependent on ambient temperaturesfUse only engine oils approved by Porsche.If in doubt ask your authorized Porsche dealer for Porsche tested and approved all-season oils.Ambient temperatureseasonal SAE Viscosity Rangeengine oilsgenerally above 14°F/–10 °C SAE 0W-30, 5W-30, 10W-30, 0W-40, 5W-40, 10W-40 and higher.generally below 14°F/–10 °C SAE 0W-30, 5W-30, 0W-40, 5W-40, 10W-40.
160 Maintenance, Car CareOil change The engine oil has to be changed at the intervals listed in your Maintenance Schedule. fPlease observe the chapter “CAPACITIES” on Page 244.We recommend that you have the engine oil changed at your Porsche dealer, who has the re-quired oils and the necessary filling equipment. If you suspect an oil leak in the engine have your dealer check it out immediately. All current engine oils are compatible with each other, i. e. when making an oil change it is not nec-essary to flush the engine if you wish to use a dif-ferent brand or grade of oil. Since, however, each brand of oil has a special composition, you should, if possible, use the same oil brand if it becomes necessary to top up between oil changes.Porsche engines have long intervals between oil changes. You can make best use of these long oil change intervals by using multigrade oils since these are largely independent of seasonal fluctua-tions in temperature. If your vehicle is used frequently in stop-and-go traffic in cold weather, the engine will not always be properly warmed up. Condensation from products of combustion may accumulate in the oil. In this case, it is advisable to change the oil more frequently so that your en-gine once again has 100% efficient engine oil. Engine oil performance class Engine oil is not only a lubricant, but also serves to keep the engine clean, to neutralize the dirt which penetrates into the engine through combus-tion and to protect the engine against corrosion. To perform these functions, the oil is provided with additives which have been specially developed for these functions. The efficiency of an oil is expressed, for example, by the API, ILSAC or ACEA classifications. Viscosity Like all liquids, engine oil is viscous when cold, and thin-bodied when warm. The viscosity of an oil is expressed by its SAE class. For cold viscosity (measured at temperatures below 32°F/0°C) the SAE class is given as a number and the letter “W” (as in winter), for hot viscosity (measured at 212°F/100°C) the SAE class is given only as a number. The viscosity of an oil is, therefore, always the same if it has the same number of an SAE class. Oils with two viscosities are called multigrade oils; oils with only one viscosity are termed single-grade oils. Single-grade oils can not be used in your engine. The viscosity of the engine oil for your Porsche has to be chosen according to the ambient tem-perature given in the engine oil recommendation table.
Maintenance, Car Care 161Brake Fluid Level fPlease observe the chapter “EXERCISE EXTRE-ME CAUTION WHEN WORKING ON YOUR VE-HICLE” on Page 154.fUse only new (unused) Original Porsche brake fluid. Warning!Brake fluid is hazardous to your health, and may be fatal if swallowed.Brake fluid also attacks paintwork. fKeep brake fluid out of children’s reach. fTake care while topping off brake fluid not to soil the luggage compartment or items of lug-gage. Checking the brake fluid level The reservoir for the hydraulic braking and clutch systems is located in the luggage compartment. 1. Open and remove cover flap A.2. Regularly check the brake-fluid level on the transparent expansion tank through the window B.The fluid level should always lie between the minimum and maximum marks.A slight decrease in the fluid level due to wear and automatic readjustment of the disc brakes is normal.If, however, the fluid level falls markedly or below the minimum mark, the braking system may have developed a leak.fHave the brake system checked without delay at an authorized Porsche dealer.
162 Maintenance, Car CareChanging the brake fluid Brake fluid absorbs moisture from the air over time. This accumulation of water lowers the boil-ing point and, under certain operating conditions, can affect the braking action.Therefore have the brake fluid changed in accord-ance with the change intervals stated in the brochure “Maintenance”. – The warning lights on the instrument panel and on the on-board computer indicate an insuffi-cient brake fluid level.– If the warning light lights up on the instrument panel and the warning message appears on the on-board computer in combination with a larger pedal travel, a brake circuit may have failed.If the warning lights should light up whilst driving:fStop immediately in a suitable place.fDo not continue driving.Consult an authorized Porsche dealer.Warning light USAWarning light Canada
Maintenance, Car Care 163Fuel Economy Fuel economy will vary depending on where, when and how you drive, optional equipment installed, and the general condition of your car. A car tuned to specifications and correctly maintained, will help you to achieve optimal fuel economy. fHave your vehicle tuned to specifications.Air cleaner should be dirt free to allow proper engine “breathing”.Battery should be fully charged.Wheels should be properly aligned.Tires should be inflated at correct pressure. fAlways monitor your fuel consumption. fDrive smoothly, avoid abrupt changes in speed as much as possible. fAvoid jack rabbit starts and sudden stops. fDo not drive longer than necessary in the lower gears. Shifting into a higher gear early without lugging the engine will help save fuel. fProlonged “warm up” idling wastes gas. Start the vehicle just before you are ready to drive. Accelerate slowly and smoothly. fSwitch off the engine if stationary for longer periods. fAny additional weight carried in the vehicle re-duces fuel economy. Always keep cargo to a minimum and remove all unnecessary items. fOrganize your trips to take in several errands in one trip. fAll electrical accessories contribute to in-creased fuel consumption. fOnly switch on the air conditioning when neces-sary. fDo not drive with the Roof Transport System mounted unless you need it.The EPA estimated m.p.g. is to be used for comparison purposes, actual mileage may be different from the estimated m.p.g., depending on your driving speed, weather conditions and trip length. Your actual highway mileage will probably be less than the estimated m.p.g. fPlease observe all local and national speed limits. Operating Your Porsche in other Countries Government regulations in the United States and Canada require that automobiles meet specific emission regulations and safety standards. There-fore, cars built for the U.S. and Canada differ from vehicles sold in other countries. If you plan to take your Porsche outside the conti-nental limits of the United States or Canada, there is the possibility that – unleaded fuel may not be available; – unleaded fuel may have a considerably lower octane rating. Excessive engine knock and se-rious damage to both engine and catalytic con-verters could result; – service may be inadequate due to lack of prop-er service facilities, tools or diagnostic equip-ment; – replacement parts may not be available or very difficult to get.Porsche cannot be responsible for the mechanical damage that could result because of inadequate fuel, service or parts availability. If you purchased your Porsche abroad and want to bring it back home, be sure to find out about ship-ping and forwarding requirements, as well as cur-rent import and customs regulations.
164 Maintenance, Car CareFuel Warning!Fuel is highly flammable and harmful to health. fFire, open flame and smoking are prohibited when handling fuel. fAvoid contact with skin or clothing. fDo not inhale fuel vapors.To prevent damage to the emission control system and engine: fNever drive the tank completely out of fuel. fAvoid high cornering speeds after the warning lights have come on. fPlease observe the chapter “EMISSION CONT-ROL SYSTEM” on Page 167.Please observe the chapter “FUEL ECONOMY” on Page 163.Please observe the chapter “LEVEL GAUGE” on Page 84.Check engine warning light If the warning lights in the instrument panel and on-board computer come on and remain on while driving, it suggests: – an improperly fastened tank cap or – refuelling with engine running. Opening the filler flap The filler opening is under the filler flap in the front right fender. fWith the vehicle unlocked, press on the front part of the filler flap (arrow) to open the flap. The filler flap is centrally locked along with the oth-er locks. If there is a defect in the automatic unlocking system: fOpen the passenger door. fPull the ring in the right-hand door aperture (arrow).
Maintenance, Car Care 165Refuelling Fuel tank capacity is listed under “Capacities”.Porsche does not recommend the use of fuel ad-ditives.Fuel is highly flammable and harmful to health.fPlease observe the chapter “CAPACITIES” on Page 244.1. Important: Stop the engine and switch off the ignition. 2. Slowly unscrew the tank cap.Hang the tank cap on the plastic strap of the filler flap. 3. Insert fuel-hose nozzle fully into the filler neck with the handle of the fuel-hose nozzle facing down. 4. Do not add further fuel once the correctly op-erated automatic fuel-hose nozzle has switched off.Fuel could spray or could run over in warm temperatures. 5. Replace the tank cap immediately after refuelling and turn it until you hear it and feel it engage. If you lose the tank cap, you must replace it only with an original part to reduce the possibility of a fire in the event of a collision. NoteThe oil level is automatically measured during refuelling.fPlease observe the chapter “OIL DISPLAY AND MEASUREMENT OF THE ENGINE OIL LEVEL” on Page 98.Fuel Recommendations Your Porsche is equipped with catalytic convert-ers and must use UNLEADED FUEL ONLY. Your engine is designed to provide optimum per-formance and fuel economy using unleaded premi-um fuel with an octane rating of 98 RON (93 CLC or AKI). Porsche therefore recom-mends the use of these fuels in your vehicle. Porsche also recognizes that these fuels may not always be available. Be assured that your vehicle will operate properly on unleaded premium fuels with octane numbers of at least 95 RON(90 CLC or AKI), since the engine’s “Electronic Oktane™ knock control” will adapt the ignition tim-ing, if necessary. The use of UNLEADED FUEL ONLY is critically important to the life of the catalytic converters. Deposits from leaded fuels will ruin the converters and make it ineffective as an emission control device. Cars with catalytic converters have a smaller fuel tank opening, and gas station pumps have smaller nozzles. This will prevent accidental pumping of leaded fuel into cars with catalytic converters.
166 Maintenance, Car CareUnleaded fuels may not be available outside the continental U.S. and Canada. Therefore, we rec-ommend you do not take your car to areas or countries where unleaded fuel may not be availa-ble. Octane ratings Octane rating indicates a fuel’s ability to resist det-onation. Therefore, buying the correct octane gas is important to prevent engine “damage”. The RON octane rating is based on the research method. The CLC (U.S. Cost of Living Council oc-tane rating) or AKI (antiknock index) octane rating usually displayed on U.S. fuel pumps is calculated as research octane number plus motor octane number, divided by 2, that is written as:The CLC or AKI octane rating is usually lower than the RON rating: For example: 95 RON equals 90 CLC or AKI Fuels containing alcohol and ether Some areas of the U.S. require oxygenated fuels during certain portions of the year. Oxygenated fu-els are fuels which contain alcohols (such as meth-anol or ethanol) or ether (such as MTBE). Under normal conditions, the amount of these compounds in the fuel will not affect driveability. You may use oxygenated fuels in your Porsche, provided the octane requirements for your vehicle are met. We recommend, however, to change to a different fuel or station if any of the following prob-lems occur with your vehicle:– Deterioration of driveability and performance. – Substantially reduced fuel economy. – Vapor lock and non-start problems, especially at high altitude or at high temperature. – Engine malfunction or stalling. Fuels containing MMT Some North American fuels contain an octane en-hancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT). If such fuels are used, your emission control sys-tem performance may be negatively affected. The check engine warning light on your instrument panel may turn on. If this occurs, Porsche recommends you stop us-ing fuels containing MMT.Portable Fuel Containers Danger!Portable fuel containers, full or partially empty, may leak causing an explosion, or re-sult in fire in case of an accident. fNever carry additional fuel in portable contain-ers in your vehicle.

Maintenance, Car Care 167Emission Control System In the interest of clean air Pollution of our environment has become a prob-lem that is of increasing concern to all of us. We urge you to join us in our efforts for cleaner air in controlling the pollutants emitted from the auto-mobile. Porsche has developed an emission control sys-tem that controls or reduces those parts of the emission that can be harmful to our environment. Your Porsche is equipped with such a system. Porsche warrants the Emission Control System in your new car under the terms and conditions set forth in the Warranty Booklet. You, as the owner of the vehicle, have the responsibility to provide regular maintenance serv-ice for the vehicle and to keep a record of all main-tenance work performed. To facilitate record keeping, have the service performed by author-ized Porsche dealers. They have Porsche trained technicians and special tools to provide fast and efficient service. To assure efficient operation of the Emission Control System: fHave your vehicle maintained properly and in accordance with the recommendations de-scribed in your Maintenance Booklet. Lack of proper maintenance, as well as im-proper use of the vehicle, will impair the func-tion of the emission control system and could lead to damage. fDo not alter or remove any component of the emission control system. fDo not alter or remove any device, such as heat shields, switches, ignition wires, valves, etc., which are designed to protect your vehi-cle’s emission control system. In addition to serious engine damage, this can result in a fire if excess raw fuel reaches the exhaust system. fDo not continue to operate your vehicle if you detect engine misfire or other unusual operat-ing conditions. Parking Warning!Danger of fire. fDo not park or operate the vehicle in areas where the hot exhaust system may come in contact with dry grass, brush, fuel spill or oth-er flammable material. fIf your car catches on fire for any reason, call the fire department. Do not endanger your life by attempting to put out the fire. Undercoating Danger!Danger of fire and serious personal injuries or death.fDo not apply additional undercoating or rust-proofing on or near the exhaust manifold, exhaust pipes, catalytic converters or heat shields. During driving the substance used for undercoating could overheat and ignite.
168 Maintenance, Car CareHow Emission Control Works When an automobile engine is running, it uses en-ergy generated through the combustion of a mix-ture of air and fuel. Depending on whether a car is driven fast or slowly or whether the engine is cold or hot, some of the fuel (hydrocarbons) may not be burned completely, but may be discharged into the engine crankcase or exhaust system. Additon-al hydrocarbons may enter the atmosphere through evaporation of fuel from the fuel tank. These hydrocarbons (HC), when released into the air, contribute to undesirable pollution. In addition, carbon monoxide (CO) and oxides of nitrogen (NOx) contribute to engine emissions. They, too, are formed during the combustion proc-ess and discharged into the exhaust system. To reduce these pollutants, your Porsche is equipped with a precisely calibrated fuel injection system to assure a finely balanced air/fuel mixture under all operating conditions. Oxygen sensor The oxygen sensor, installed in the exhaust pipe continuously senses the oxygen content of the exhaust and signals the information to an electron-ic control unit. The control unit corrects the air/fuel ratio, so the engine always receives an accu-rately metered air/fuel mixture. Crankcase ventilation Through crankcase ventilation, undesirable emis-sions from the engine crankcase are not permit-ted to reach the outside atmosphere. These emis-sions are recirculated from the crankcase to the air intake system. From here the emissions mix with the intake air and are later burned in the en-gine. Catalytic converters The catalytic converters are efficient “clean-up” devices built into the exhaust system of the vehi-cle. The catalytic converters burn the undesirable pollutants in the exhaust gas before it is released into the atmosphere. The exclusive use of unleaded fuel is critical-ly important for the life of the catalytic con-verters. Therefore, only unleaded fuel must be used. The catalytic converters will be damaged by: – push or tow starting the vehicle – misfiring of the engine – turning off the ignition while the vehicle is mov-ing or – driving until the fuel tank is completely empty – by other unusual operating conditions. fDo not continue to operate your vehicle under these conditions, since raw fuel might reach the catalytic converters. This could result in overheating of the converters. Federal law pro-hibits use of leaded fuel in this car.
Maintenance, Car Care 169Fuel Evaporation Control Fuel tank venting The evaporation chamber and the carbon canister prevent fuel from escaping to the atmosphere at extreme high outside temperatures, when driving abruptly around curves and when the car is parked at an incline or in any other nonlevel position. Vapor control system and storage When the fuel tank is filled, vapors are collected in the evaporation chamber by a vent line leading the vapors to the carbon canister where they are stored as long as the engine does not run. Purge system When the engine is running, the fuel vapors from the canister will be mixed with fresh air from the ambient air of the canister. This mixture will be directed to the intake air housing by the tank vent line, mixed with the intake air and burned during normal combustion.Washer FluidThe reservoir, with a blue screw cap, is in the lug-gage compartment, to the rear left. Capacity – Without headlight cleaning system:approximately 2.6 quarts (2.5 liters). – With headlight cleaning system: approximately 6.3 quarts (6.0 liters). Topping off washer fluidClean water is generally not enough to clean the windshield and headlights.Depending on the season, mix the water with win-ter cleaner giving antifreeze protection or a sum-mer cleaner. Follow the instructions for the mixing ratio. fOnly use cleaner fluids authorized by Porsche.1. Please note all the information on the refill con-tainer of the cleaning agent.2.

170 Maintenance, Car CarePower Steering Power steering is assisted by hydraulic auxiliary forces.The hydraulic fluid reservoir is located in the en-gine compartment. NoteThe flow noise heard at full steering lock is design-related and does not indicate a defect in the steer-ing system. Warning!Risk of accident. When the engine is stopped (e.g. when being towed) or the hydraulic system fails, there is no assistance for steering.Therefore, substantially more force will have to be exerted in order to steer. fExercise great care when being towed. fHave the fault remedied at your nearest author-ized Porsche dealer. Checking hydraulic fluid fPlease observe the chapter “EXERCISE EXTRE-ME CAUTION WHEN WORKING ON YOUR VE-HICLE” on Page 154.fOnly use hydraulic fluid authorized by Porsche.Specification:Please observe the chapter “CAPACITIES” on Page 244.Check the fluid level with the engine stopped and cold (approximately 68°F/20°C).1. Open the engine compartment lid. 2. Open the reservoir cap. 3. Wipe measuring rod.Close cap and reopen. The fluid level should lie in the area below the “Cold” marking. Add hydraulic fluid if necessary. 4. Close cap carefully.Close engine compartment lid. Noticeable loss of fluid indicates leakage in the system.The cause should be remedied immediately at an authorized Porsche dealer.
Maintenance, Car Care 171Air Filter A dirty air filter not only reduces engine perform-ance, but can lead to premature engine wear. Regular filter replacement is part of the routine maintenance service. fIn dusty conditions, check the filter element more frequently and replace if necessary.Combination Filter The fresh air passing through the combination fil-ter into the passenger compartment is virtually free of dust, pollen, and unpleasant odors. fIf the outside air is polluted by exhaust fumes, press the circulating-air button.A dirty filter can be the cause of reduced air flow: fHave filter replaced by your authorized Porsche dealer.Regular filter replacement is part of the routine maintenance service. Manual Transmission Oil The transmission oil has to be checked and changed at the intervals listed in your Maintenance Schedule. fPlease observe the chapter “CAPACITIES” on Page 244. We recommend that you have the transmission oil changed at your Porsche dealer, who has the re-quired lubricants and the necessary filling equip-ment. If you suspect an oil leak in the transmission, have your authorized Porsche dealer check it out imme-diately. Automatic Transmission Fluid The torque converter and the transmission are lu-bricated with Automatic Transmission Fluid (ATF). The final drive requires transmission oil. See “Ca-pacities”. Do not tow the car or run the engine without ATF in the transmission. The automatic transmission may be damaged by even a tiny speck of dirt, only a clean funnel or spout must be used when adding ATF. The ATF and transmission oil has to be checked and changed at the intervals listed in your Mainte-nance Schedule. We recommend that you have the ATF and trans-mission oil changed at your Porsche dealer, who has the required lubricants and the necessary fill-ing equipment. If you suspect an oil leak in the transmission, have your authorized Porsche dealer check it out imme-diately.

174 Maintenance, Car CareCar Care Instructions fPlease observe the chapter “EXERCISE EXTRE-ME CAUTION WHEN WORKING ON YOUR VE-HICLE” on Page 154.Regular and correct care helps to maintain the value of your car and is also a precondition for the New Vehicle Warranty and the Anti Corrosion Warranty. Your authorized Porsche dealer has specially developed car-care products from the Porsche program available either singly or as complete car-care sets. They will be pleased to help you select suitable products. Whether you use Porsche products or other commercially available cleaning agents first make sure of their correct application. A Porsche that is well-cared for can look like new for years. It all depends on the amount of care the owner is willing to give the car. Warning!Risk of serious personal injury or damage to the vehicle or property.Cleaning agents may be hazardous to your health.Most chemical cleaners are concentrates which require dilution. High concentrations might cause problems ranging from irritation to serious injury as well as damage to your vehicle. fKeep cleaning agents out of reach from chil-dren. fObserve all caution labels. fAlways read directions on the container before using any product. These directions may con-tain information necessary to avoid personal injury. fDo not use fuel, kerosene, naphtha, nail polish remover or other volatile cleaning fluids. They may be toxic, flammable or hazardous in other ways. Only use spot removing fluids in a well vented area. fDo not clean the underside of chassis, fend-ers, wheel covers, etc., without protecting your hands and arms as you may cut yourself on sharp-edged metal parts. Moisture and road salt on brakes may affect brak-ing efficiency. fTest the brakes after each vehicle washing.
Maintenance, Car Care 175Washing The best method of protecting your car from the damaging effects of the environment is frequent washing and the application of a preservative. The underside of your vehicle should also be thorough-ly washed for cinders, salt or sanding at winter’s end. The longer salt, road dust and industrial dust, dead insects, bird droppings or substances from trees (resin, pollen) are allowed to remain on the bodywork, the more serious is their harmful ef-fect. New cars should be washed carefully with plenty of clear water to protect the new paint work. Dark paint finishes show up the smallest of surface damage (e.g., scratches) more readily than lighter colors. Dark colors are also more susceptible to scratch-ing because of the composition of their pigments and require particularly careful paint care. fDo not wash your car in bright sunlight or while the bodywork is still hot. fWhen washing by hand, use abundant water, a soft sponge or wash brush, and Porsche car shampoo. fBegin by spraying the body thoroughly with wa-ter to rinse away loose dirt. fAfter washing, rinse the car with plenty of wa-ter and then dry with a chamois leather.Do not use the same chamois leather for dry-ing as you use for cleaning the windshield and windows. Warning!Moisture which gets on to the brakes during a car wash can reduce braking efficiency or make the brakes pull unevenly which could increase the danger of an accident, causing serious personal injuries or death. fAlways apply the brakes a few times after washing the car to test braking efficiency and dry the brake discs.When doing this, take care not to hamper other road users behind you (traffic conditions per-mitting). Automatic car washes Optional add-on parts or parts which project beyond the contours of the vehicle may be damaged by design features (e.g. brushes) of au-tomatic car washes. The following parts are particularly susceptible to damage: – Windshield wipers (always switch them off to prevent them wiping unintentionally in intermit-tent or sensor operation) – External antennas (always unscrew)– Roof Transport System (always remove com-pletely) – Rear spoiler– Wheels (the wider the rim and the lower the tire height, the greater the risk of damage) – High-gloss wheels (to prevent these from get-ting scratched, do not clean with the wheel-cleaning brushes of the car wash). fPlease consult the operator before using auto-matic car washes. fWash and dry by hand all points not reached by a car wash, such as door and lid seams or door sills. NoteAutomatic car washes spray water at odd angles and high pressures, which are not seen in normal driving. Therefore, water can sometimes find its way into the passengers compartment during or shortly after the car wash.f f f
176 Maintenance, Car CareDoor lock fTo prevent the door lock from freezing during the cold season, the lock cylinder should be covered during a wash. fShould the lock freeze, use an ordinary de-icer. In many cases, a well warmed key can help. Never use excessive force.Paint fNever rub a dusty car with a dry cloth since dust particles are abrasive and could dull and damage the surface finish.The paintwork of your car is exposed to all types of mechanical and chemical conditions, particular-ly climatic ones such as bright sunlight, rain, frost and snow. Ultraviolet light, rapid changes in tem-perature, rain, snow, industrial dust and chemical deposits constantly attack the paint which is only able to withstand such exposure in the long term if it is given regular care and attention. fDo not apply silicone polishes to the windshield or windows. fDo not treat matt-painted components with preservatives or polishes as this will spoil the matte effect. Preservation The paint surface becomes dull over time due to weathering. It is therefore necessary to preserve the paint regularly.This keeps the paint shiny and elastic. Dirt is pre-vented from adhering to the paint surface and in-dustrial dust is prevented from penetrating the paint. Provided it is washed and treated with preserva-tive regularly, the brand new finish of your car will be retained for years to come. fApply the Porsche paint preservative after the car wash and polish it dry to obtain a bright fin-ish or simply add a liquid preservative regularly to the final rinse water. PolishingDo not resort to using Porsche polish until it be-comes evident that the normal preservatives no longer produce the desired finish. Spots and stains fRemove tar stains, grease, oil spots and dead insects as soon as possible with Insect Remov-er. They can cause discoloration if allowed to remain on the paintwork. fWash the affected area immediately after treat-ing it. Minor paint damage fHave minor paint damage, such as scratches, scores or chips caused by flying stones, re-paired immediately by your authorized Porsche dealer before corrosion sets in.However, if there are already traces of corrosion, they must first be removed carefully and thorough-ly. Coat the area with a rust-proofing primer and finish off with a top coat. The paint code and color number are found on the vehicle’s paint data plate.
Maintenance, Car Care 177Engine compartment The engine compartment and the surface of the engine are treated with a corrosion-inhibitor at the factory. If degreasing solvents are used to clean the en-gine compartment or the engine is washed down, the process almost invariably removes the corro-sion-inhibiting coating. It is then absolutely neces-sary to have a durable preservative applied to all surfaces, body seams, joints and assemblies in the engine compartment. This also applies when corrosion-inhibitor parts are replaced. Caution!Risk of damage to the alternator. fDo not point the cleaning jet directly at the al-ternator, or cover the alternator.Effective corrosion-proofing is particularly impor-tant during the cold weather season. If your car is driven frequently in areas where salt has been spread on the roads, the whole engine compart-ment should be cleaned thoroughly after the win-ter to prevent salt from causing any lasting dam-age. A full under-body wash should also be per-formed at the same time. Windows The road dust which settles on the windshield and windows contains particles of tire rubber and oil residue. The interior trim and upholstery release particles, particularly in strong sunlight, which col-lect on the insides of the windows. These deposits are augmented by impurities in the air which en-ters the car through the fresh air vents. fClean all windows regularly, inside and outside, with Porsche window cleaner. fIf you use a chamois leather for the windows, do not use it for paintwork as it will otherwise pick up a certain amount of preservative or polish and could smear the windows and thus impair vision. fRemove dead insects with Porsche insect re-mover. NoteDoor windows feature a water-repellent (hydro-phobic) coating which prevents soiling of the windows. This coating is subject to natural wear and can be renewed.fConsult an authorized Porsche dealer.Wiper blades Wiper blades that are in perfect condition are vital for a clear view. fReplace the wiper blades twice per year (be-fore and after the cold season) or whenever wiper performance deteriorates. fPeriodically clean the wiper blades with Porsche window cleaner, especially after the vehicle has been washed in a car wash.If they are very dirty (e.g. with insect remains), they can be cleaned with a sponge or cloth. Undercoating As it is not possible to exclude the risk of damage to this protective coating in day to day driving, it is advisable to have the underside of the car in-spected at certain intervals – preferably before the start of winter and again in spring – and the un-dercoating restored as necessary. Your authorized Porsche dealer is familiar with the bodyseal treatment procedures and has the nec-essary equipment for applying factory approved materials. We recommend that you entrust them with such work and inspections. Unlike conventional spray oils, undercoating and rust-proofing compounds based on bitumen or wax do not attack the sound-proofing materials ap-plied at the factory. f f f
178 Maintenance, Car Care Warning!Danger of fire and serious personal injuries. fDo not apply additional undercoating or rust-proofing on or near the exhaust manifold, ex-haust pipes, catalytic converters or heat shields. During driving the substance used for undercoating could overheat and ignite. fBefore applying fresh underseal, carefully re-move any deposits or dirt and grease. Once it has dried, the new undercoating compound forms a tough protective coating which pro-vides efficient rust-proofing of the floor panels and components. fAlways apply a fresh coating of suitable pre-servative to unprotected areas after cleaning the underside of the body, the transmission, the engine or carrying out repairs to under-body, engine or transmission components.Effective rust-proofing is particularly important during the cold weather season. If your car is driv-en frequently in areas where salt has been spread on the roads, the whole engine compartment should be cleaned thoroughly after the winter to prevent salt from causing any lasting damage. A full under-body wash should also be performed at the same time. Light alloy wheels fPlease observe the chapter “WASHING” on Page 175.Pitting may occur if metallic particles which cause contact corrosion (e.g. brass or copper in brake dust) are allowed to remain on the aluminum for too long. fIf possible, wash the wheels with a sponge or wash brush about every two weeks. In areas where salt is spread on winter roads or there is a lot of airborne industrial dust, it is best to clean the wheels weekly.The Porsche Light Alloy Wheel Cleaner (ph-value 9.5) can be used for this pur-pose.If the ph-value of the detergent is incor-rect, the protective coating on the wheels will be destroyed.Polishes which dissolve oxides, such as those frequently used for other metals, or abrasive tools or agents are unsuitable because they break down the oxide film of the protective coating and will cause discoloration of the wheel. fEvery three months, after cleaning, coat the wheels with a car wax or non-corrosive grease (vaseline). Using a clean cloth thoroughly rub the grease into the surface. Door, roof, lid and window seals fWash dirt (e.g. abrasion, dust, road salts) from all seals regularly using warm soapy water. Do not use any chemical cleaning agents or sol-vents.When there is a frost hazard, the outer door seals and the front and rear lid seals can be protected against freezing into place by a suitable care prod-uct. In order to prevent damage to the anti-friction coating, the inner door seals must not be treated with care products.
Maintenance, Car Care 179Headlights, lights, interior and exterior plastic parts fUse only clean water and a little dishwashing detergent to clean light lenses, plastic head-light lenses, plastic parts and surfaces.Do not clean when dry.Use a soft sponge or a soft, lint-free cloth. Gen-tly wipe the surface without applying too much pressure.The Porsche inside window cleaner is also suit-able for cleaning plastic surfaces. Follow the cleaning instructions on the container.Never use other chemical cleaners or solvents. fRinse cleaned surfaces with clear water. Leather Characteristics and special features The natural surface markings of leather, e.g. creases, healed scars, insect sting marks, struc-tural differences and slight variations in shade and grain add to the attractiveness of the natural leath-er product.A special mention must be made here of natural leather. For natural leather, carefully selected hides of the highest quality are used. It is not covered com-pletely with dye on production.“Nature’s signature” is therefore easily recogniza-ble.This fine material is distinguished by an outstand-ing seating comfort, special suppleness and a typ-ical patina. Leather care and treatment fClean all types of leather regularly to remove fine dust using a soft, damp, white woollen cloth or a commercially available microfibre cloth. fRemove heavy contamination with Porsche leather cleaner. Please always follow the instructions for use given on the containers.Caustic cleaners and hard cleaning objects must not be used. Perforated leather must under no circum-stances get wet on its reverse side. Once cleaned, leather (particularly the heavily stressed leather seats) must be treated only with Porsche leather care liquid. f f f
180 Maintenance, Car CareFabric, upholstery, carpets and floor-mats fUse only a vacuum cleaner or a medium stiff brush. fRemove stains and spots with Porsche stain remover.The Porsche range of accessories includes non-skid floor-mats to protect the carpets in summer and winter. Warning!Risk of an accident. fAlways check the movement of the pedals be-fore driving and make sure that they are not ob-structed by a floor-mat or any other object. fSecure the floor-mat to prevent it from sliding into positions that could interfere with the safe operation of your vehicle - do not install them loosely in the vehicle.Your Porsche dealer will be glad to offer you nonskid floor-mats of the correct size.Alcantara fDo not use a leather care product to clean Alcantara. For regular care it is sufficient to clean the cover with a soft brush. Cleaning when lightly soiled fWet a soft cloth with water or a neutral soap solution and wipe off the dirt. Cleaning when heavily soiled fWet a soft cloth with lukewarm water or thinned white spirit and dab the dirt from the outside in. Safety belts If it becomes necessary to clean the belts, you can use any mild washing agent.Allow the belts to dry prior to retracting, but avoid direct sunlight. fOnly use suitable cleaners.If unsuitable cleaners are used or any attempt is made to dye or bleach the belts, the web-bing may be weakened and thus constitute a safety risk.
Maintenance, Car Care 181Storing your Porsche If you intend to store your Porsche for a prolonged period, please consult your authorized Porsche dealer. The staff will be glad to advise you on the most suitable and necessary methods. fClean your vehicle thoroughly inside and out-side. Clean the engine compartment. The under carriage and chassis components should be free of dirt and salt deposits. fFill up the fuel tank. fChange the oil and oil filter, and run the engine for several minutes. fIncrease the tire pressure to 58 psi (4 bar).It is not recommended to lift the vehicle, due to the possibility of corrosion on shock absorber piston shafts.The vehicle should be moved slightly, approxi-mately every four weeks, to prevent flat spot on the tires. Climate control The air conditioning system should be in good working condition and fully charged. Windshield/Headlight washer fCheck and correct antifreeze/cleaning solution level as necessary. Electrical system fRemove the battery from the vehicle and store it in a cool dry place, not on a cement floor. When the battery is disconnected, the alarm system is deactivated. fRecharge the battery every 3 months. If the battery remains in the vehicle with the cables connected, it is necessary to check, remove and recharge the battery every 2-3 weeks. Do not fast charge the battery. fPlease observe the chapter “BATTERY” on Page 212.Vehicle interior The interior must be dry, especially in the area of the floor carpets. The use of drying agents (Silica-Gel) is recommended in vehicles with leather inte-rior and in areas with high humidity. The recom-mended amount is 3 fabric bags of 1.1 lbs. (500 grams) each placed on the floor carpets. Windows, doors and lids must be closed. The air vents should be opened.

184 Practical Tips, Emergency ServiceExercise Extreme Caution when Working on your Vehicle Danger!Ignoring the following instructions may cause serious personal injury or death. fThe engine compartment of any motor vehicle is a potentially hazardous area. If you are not fully familiar with proper repair procedures, do not attempt the adjustments described on the following pages. This caution also applies to the entire vehicle. fOnly work on your vehicle outdoors or in a well ventilated area. fEnsure that there are no open flames in the area of your vehicle at any time when fuel fumes might be present. Be especially cau-tious of such devices such as hot water heat-ers which ignite a flame intermittently. fBefore working on any part in the engine com-partment, turn the engine off and let it cool down sufficiently. Hot engine compartment components can burn skin on contact. fBe alert and cautious around engine at all ti-mes while the engine is running.If work has to be performed with the engine running, always set the parking brake, and make sure the shift lever is in neutral position or the selector lever in position P.fIn particular, be very careful to ensure that items of clothing (ties, shirt, sleeves etc.), jew-elry, long hair, hand or fingers cannot get caught in the engine-compartment blower, fan, belts or other moving parts.The radiator and radiator fans are in the front of the car.The engine-compartment blower is mounted on the engine-compartment lid.The engine-compartment blower can start or continue running as a function of temperature, even with the engine switched off.Carry out work in these areas only with the en-gine off, the ignition switched off, and exercise extreme caution.fYour Porsche is equipped with an electronic ig-nition system. When the ignition is on, high volt-age is present in all wires connected with the ignition system; therefore, exercise extreme caution when working on any part of the engine while the ignition is on or the engine is running. fAlways support your car with safety stands if it is necessary to work under the car.fWhen working under the car without safety stands but with the wheels on the ground, make sure the car is on level ground, the wheels are blocked, and that the engine cannot be started.Remove the ignition key.fDo not smoke or allow an open flame around the battery or fuel.Keep a fire extinguisher in close reach. fIncomplete or improper servicing may cause problems in the operation of the car. If in doubt about any servicing, have it done by your au-thorized Porsche dealer.Improper maintenance during the warranty pe-riod may affect your Porsche warranty cover-age. fSupplies of fluids, e.g. engine oil, brake fluid or coolant, are hazardous to your health. Keep these fluids out of children’s reach and dispose of them in accordance with the appro-priate regulations. fSome countries require additional tools and special spare parts to be carried. Please make enquiries before driving abroad.
Practical Tips, Emergency Service 185Tires/Wheels The original equipment tires and wheel rims on your Porsche comply with all applicable Federal Motor Vehicle Safety Standards. For your safety remember the following: – Wheel rims and wheel bolts are matched to fit your Porsche. – If you intend to use other than original equip-ment wheels, be sure that they conform to Porsche specifications for your model.Only tires with the same make and with the same specification code (e.g. “N0”, “N1”...) can be mounted. – The use of wheel rims and wheel bolts that do not meet specifications of the original factory installed equipment will affect the safe opera-tion of your vehicle. – Before you plan on exchanging wheels, or snow tires already mounted on the wheel rims, consult your authorized Porsche dealer. Your dealer has the technical information necessary to advise you which wheel rims and wheel bolts are compatible with the original factory instal-lations. Danger!Risk of loss of control and serious personal injury or death. fIf while driving, your vehicle experiences a sud-den vibration or ride disturbance, and/or you suspect that possible damage to your tires or vehicle has occurred, you should immediately reduce your speed without excessive use of the brakes. fStop the vehicle as soon as possible, and in-spect the tires.If you cannot determine the cause for the dis-turbance, have your vehicle towed to the near-est Porsche or tire dealer to have your vehicle or tire(s) inspected. fContinuing to operate the vehicle without cor-rection could result in a loss of control and serious personal injury.
186 Practical Tips, Emergency ServiceUniform Tire Quality Grading Quality grades can be found where applicable on the tire sidewall between tread shoulder and max-imum section width. Example All passenger car tires must conform to Federal Safety Requirements in addition to these grades. Treadwear The treadwear grade is a comparative rating based on the wear rate of the tire when tested un-der controlled conditions on a specific govern-ment test course.For example, a tire graded 150 would wear one and a half (1-1/2) times as well on the government course as a tire graded 100.The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to var-iations in driving habits, service practices and dif-ferences in road characteristics and climate.
Practical Tips, Emergency Service 187Traction AA, A, B, C The traction grades, from highest to lowest, are AA, A, B, and C and they represent the tire’s ability to stop on wet pavement as measured under con-trolled conditions on specified government test surfaces of asphalt and concrete.A tire marked C may have poor traction perform-ance. Warning!The traction grade assigned to this is based on braking (straight-ahead) traction tests and does not include cornering (turned) traction, accelera-tion, hydroplaning or peak traction characteris-tics. Temperature A, B, C The temperature grades are A (the highest), B and C, representing the tire’s resistance to the gener-ation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel.Sustained high temperatures can cause the mate-rial of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure.The grade C corresponds to a level of perform-ance which all passenger car tires must meet un-der the Federal Motor Vehicle Safety Standard No. 109.Grades B and A represent higher levels of per-formance on the laboratory test wheel than the minimum required by law. Warning!The temperature grade for this tire is established for a tire that is properly inflated and not overload-ed.Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure.
188 Practical Tips, Emergency ServiceTire pressures Warning!Incorrect tire pressure causes increased tire wear and adversely affects road handling. fAlways use an accurate tire pressure gauge when checking inflation pressures. fDo not exceed the maximum tire pressure list-ed on the tire sidewall. Please observe the chapter “TIRE PRESSURE PLATE” on Page 239.fCold tire inflation pressure means: all tires must be cold, ambient temperature maximum (68°F, (20°C), when adjusting the inflation pres-sure. Avoid sunlight striking the tires before measur-ing cold pressures, since the pressures would rise from temperature influence. fValve caps protect the valve from dust and dirt, and thus from leakage. Always screw caps tightly down. Replace missing caps immediately. fUse only plastic valve caps.fDo not use commercially available sealant or tire inflating bottles. Only use Porsche approved tire sealant.The tire pressure must match the prescribed val-ue. You can find information on tire pressure:– on Page 3 of this Owner’s Manual – and in the left door aperture.These values are for cold tires (68°F (20 °C)).fCheck the tire pressure at least every 2 weeks. Always check when tires are cold.When tires are warm, the tire pressure is increased.fNever let air out of hot tires. This could cause the tire pressure to fall below the prescribed value.Insufficient tire filling pressure can cause tires to overheat and thus be damaged – even invisibly. Hidden tire damage is not eliminated by subse-quently correcting the tire pressure.Overloading Danger!Risk of personal injury, loss of control and damage to vehicle parts.fDo not overload your vehicle.

190 Practical Tips, Emergency ServiceTire traction Warning!When driving on wet or slushy roads, a wedge of water may build up between the tires and the road. This phenomenon is known as “hydroplane” and may cause par-tial or complete loss of traction, vehicle control or stopping ability. fReduce speed on wet surface to prevent this. Tire life Tire life depends on various factors, i. e., road surfaces, traffic and weather conditions, driving habits, type of tires and tire care. fInspect your tires for wear and damage before driving off. If you notice uneven or substantial wear, wheels might need alignment or tires should be balanced or replaced.Tire wear The original equipment tires on your Porsche have built-in tire wear indicators. They are molded into the bottom of the tread grooves and will appear as approximately 1/2 in. (12 mm) bands when the tire tread depth is down to 1/16 of an in. (1.6 mm). When the indicators appear in two or more adja-cent grooves, it is time to replace the tires. We recommend, however, that you do not let the tires wear down to this extent. Worn tires cannot grip the road surface properly and are even less effective on wet roads. In the United States, state laws may govern the minimum tread depth permissible. Follow all such laws. Danger!Driving on worn tires can result in loss of con-trol of the vehicle and could cause serious personal injuries or death. fDo not drive with worn tires or tires showing cuts or bruises as they may lead to sudden deflation and loss of control which could cause severe personal injury. fSpecialized high performance tires on high performance sports cars exhibit more wear than those on a family sedan, or even a high performance sedan. Therefore, it is important to check your tire pressure and condition at least every two weeks. If you notice that tires are wearing unevenly, con-sult your Porsche dealer. Uneven wear may not always be due to improper wheel alignment. It can be the result of individual driving habits such as cornering at high speeds. If the tire pressure is not checked and adjusted regularly, abnormal tire wear can also occur.
Practical Tips, Emergency Service 191Tire care fAvoid damaging tires and wheel rims. fIf you must drive over a curb or other obstacle, drive slowly and at an obtuse angle. fCheck tires for uneven wear and damage before driving off. fRemove imbedded material. fReplace worn or damaged tires immediately. fKeep oil, fuel, brake fluid, etc. away from tires. fReplace missing valve stem caps. fKeep tires inflated correctly. fWash tires when washing the vehicle. Also clean inner side of wheels.fDo not use abrasive cleaners when washing the wheels.fCheck wheel rims for corrosion.fRemove road salt, if driving in winter.Tire damage, puncture fCheck tires for imbedded material, cuts, punc-tures, cracks and bulges (side wall) before driv-ing off.In case of tire damage, where it is uncertain wheth-er there is a break in the ply with all its conse-quences or tire damage caused by thermal or me-chanical overloading due to loss of pressure or any other prior damage, we recommend that the tire be replaced for safety reasons. If one faulty tire is replaced it should be noted that the difference in tread depth on one axle must not exceed 30 %. Handling inconsistencies may result. fPerform a visual inspection if necessary. Danger!Risk of serious personal injury or death. Driving the vehicle with low tire pressure increases risk of a tire failure and resulting loss of control. Furthermore, low tire pres-sure increases rate of wear of the affected tires.fCheck tires – including sidewalls – regularly for foreign bodies, nicks, cuts, cracks and bulges.fAfter driving off road, examine tires for signs of damage such as cuts, tears, bulges or for-eign objects stuck in the tread. Replace a dam-aged tire if necessary.fCross curb edges slowly and at right angles if possible. Avoid driving over steep or sharp curbs.fIn cases of doubt, have the wheel (particularly the inner side) checked by an authorized Porsche dealer.
192 Practical Tips, Emergency ServiceTire replacements If in doubt, contact your Porsche dealer.Use only tire makes and types approved by Porsche. If you do not use a Porsche recommended replacement tire, make sure that you purchase your new tires from a reputable tire dealer and that the dealer complies with all manufacturers warnings for those tires. Only tires with the same make and with the same specification code (e.g. “N0”, “N1”...) can be mounted. Before mounting new tires, check with your Porsche dealer about the current release status. Use tires with “ZR” quality standards. There are currently no standards concerning tire strength at speeds above 150 mph (240 km/h). Tires should be replaced no less than on one axle at the time. Only tires of the same make and type must be used. Mixed tires are not permissible. Initially, new tires do not have their full traction. You should therefore drive at moderate speeds during the first 60 - 120 miles (100 - 200 km). If new tires are installed only on one axle, a notice-able change in handling occurs due to the different tread depth of the other tires. This happens especially if only rear tires are re-placed. However, this condition disappears as the new tires are broken in. fPlease adjust your driving style accordingly.Installation of new tires should only be done by a qualified tire technician. Valves Rubber valve stems must be replaced every time a tire is replaced.For metal valves, the installation and replacement instructions must be observed.fUse only genuine Porsche metal valves.fProtect the valve inserts against soiling with valve caps.Soiled valve inserts can cause a gradual loss of air.fUse only plastic valve caps.Parking at the curb Warning!Hard impacts against curbs (or traffic islands) are dangerous and may cause hid-den tire damage which is not noticeable until later. Such damage can result in accidents at high speeds causing severe personal injury.Depending on the force of impact, the edge of the rim can also be damaged. fIf you are in doubt, have the wheel checked by an expert, particularly if you suspect damage on the inside. fIf you must drive over a curb or other obstacle, drive slowly and at an obtuse angle. Exercise care when parking along curbs.
Practical Tips, Emergency Service 193Wheel alignment, wheel balancing As a precaution, have wheels with summer tires balanced in the spring, and those with mud and snow tires before winter. Unbalanced wheels may affect car handling and tire life.Only the specified weights may be used for wheel balancing. Self-adhesive weights must not come into contact with cleaning agents, since they could drop off.Uneven tread wear indicates wheel imbalance. In this event, the vehicle should be checked at an au-thorized Porsche dealer. Warning!If, during a journey, uneven running or vibra-tions occur that could be caused by damage to tires or the car, the speed must be re-duced immediately, but without braking sharply. If you continue your trip without having the cause of the fault remedied, you might lose control of your vehicle which could cause se-vere personal injury. fStop the vehicle and check the tires. fIf no cause for the fault can be found, drive carefully to the nearest authorized Porsche dealer. Removing and storing tires fAfter changing, adjust tire pressure and torque wheel bolts diagonally to 94 ftlb (130 Nm). Tires must always remain on the same side of the vehicle.When wheels are removed, the direction of rotation and position of each wheel should be marked. Example FR (front right), FL, RR and RL. Wheels must always be fitted in accordance with their marking. The preception that tire durability and perform-ance are immune to the effects of storage and age is unfounded. Chemical additives, which make the rubber elas-tic, lose their effectiveness in the course of time and the rubber becomes brittle and cracks. Therefore, the tires should be inspected from time to time. NoteUnder no circumstances should tires older than 6 years be used on your Porsche. The age of the tire can be obtained from the “DOT” code number. If, for example, the last four num-bers read 1204, then the tire was produced in the 12th week of 2004. fStore tires in a cool and dry place.
194 Practical Tips, Emergency ServiceSnow tires For a better grip on snow and ice, use radial M+S tires with studs. Check with your local Motor Vehicle Bureau for possible restrictions. Danger!Risk of loss of control and damage to the vehicle as well as serious personal injury or death.The standard tires profile and rubber mixture are optimized for wet and dry driving condi-tions, and may not prove favorable for snow conditions. fTherefore install M+S tires before driving in such conditions. Before mounting snow tires, consult with your Porsche dealer. He has the technical information necessary to advise you on wheel and tire compatibility. Snow tires should have the same load capacity as original equipment tires and should be mounted on all four wheels. Snow tires with studs should be run at moderate speeds when new in order to give the studs time to settle. Danger!Tires with badly worn treads and studs are very dangerous and could cause accidents resulting in serious personal injuries or death. fMake sure they are replaced immediately. Do not drive a vehicle equipped with snow tires at prolonged high speed. Snow tires do not have the same degree of trac-tion on dry, wet or snowfree roads as a normal tire. Furthermore, snow tires wear rapidly under these conditions. Comply with all state and local laws governing snow tire and tread depth requirements. Danger!Risk of accident and serious personal injury or death due to excessive speed.fAlways check the maximum speed rating on the tire sidewall on any tire on the vehicle.fNever exceed the maximum speed rating of the tires. Fit winter tires to both axles well before the cold season begins. Your authorized Porsche dealer will be pleased to advise you.Maintenance noteWe recommend fitting winter tires on the vehicle at temperatures below 45°F (7°C ).Winter tires lose their traction capability when their tread depth falls below 5/32 in. (4 mm).
Practical Tips, Emergency Service 195Snow chains Caution!Risk of damage to body, axle or brake com-ponents. fFit snow chains only to the rear wheels, and only with the tire/rim combination listed in the Technical Data.To ensure adequate clearance between chain and body, Porsche recommends only the use of fine-link chains such as those approved by Porsche. fFollow instructions issued by the supplier of the chains. Different states and countries have varying statu-tory requirements regarding maximum speed. Check with local authorities for possible restric-tions. fRemove chains as soon as the roads are free of ice and snow. Tire designations Due to new speed and load ratings for radial tires, new designations have come into force for snow tires for your Porsche. The designation to be used for ZR tires is e.g., 265/40 ZR 18 (Z = code letter for radial tires for speeds above 150 mph / 240 km/h).

198 Practical Tips, Emergency ServiceLoading InformationDefinitionsThe Curb weight - actual weight of your vehicle - vehicle weight including standard and optional equipment, fluids and emergency tools. This weight does not include passengers and cargo.The Gross Vehicle Weight is sum of the curb weight and the weight of passengers and cargo combined.The Gross Vehicle Weight Rating is the maxi-mum total weight of vehicle, passengers, luggage and optional equipment.The Gross Axle Weight Rating is the maximum load limit for the front or the rear axle. This infor-mation is located on the safety compliance sticker located in the driver’s side door jamb. For determining the compatibility of the tire and vehicle load capabilities:fPlease observe the chapter “TIRES, RIMS, TRACKS” on Page 242.The load capacity coefficient (e.g. “100”) is a min-imum requirement.The Gross Combined Weight Rating is the maximum total weight rating of vehicle, passen-gers and cargo.The Vehicle Capacity Weight - Load Limit - is the maximum total weight limit specified of the load (passengers and cargo) for the vehicle. This is the maximum weight of passengers and cargo that can be loaded into the vehicle. This informa-tion can be found on the tire pressure plate.The maximum loaded vehicle weight is the sum of curb weight, accessory weight, vehicle ca-pacity weight and production options weight.The load rating is the maximum load that a tire is rated to carry for a given inflation pressure.The maximum load rating is the load rating for a tire at the maximum permissble inflation pres-sure.The cargo capacity is the permissible weight of cargo, the substracted weight of passengers from the load limit.fNever exceed the permissible limits. Danger!Risk of personal injury, loss of control and damage to vehicle.fNever exceed the specified axle loads. Over-loading can shorten the service life of the tires and car, as well as lead to dangerous vehicle reactions and long braking distances. Damage due to overloading is not covered by the vehi-cle warranty.
Practical Tips, Emergency Service 199Example for determining the combined weight of occu-pants and cargoVehicle Load CapacityfThe combined weight of occupants and cargo should never exceed the weight shown on the tire plate in the vehicle.Please observe the chapter “TIRE PRESSURE PLATE” on Page 239.fNever exceed the number of passengers shown on the tire pressure plate in the vehicle.Determining the combined weight of occupants and cargo:fAdd the weight of all occupants and then add the total luggage weight (figure).Steps for determining correct load limit1. Locate the statement "The combined weight of occupants and cargo should never exceed XXX pounds" on your vehicle’s placard (depending on the date of manufacture)2. Determine the combined weight of the driver and passengers that will be riding in your vehi-cle. 3. Subtract the combined weight of the driver and passengers from XXX kilograms or XXX pounds.4. The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the "XXX" amount equals 1400 lbs. and there will be five - 150 lb passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs. (1400 - 750 (5 x 150) = 650 lbs.) 5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available car-go and luggage load capacity calculated in Step 4.

Slow battery charging 1. Pay attention to all warnings and follow instruc-tions that come with your battery charger. 2. When charging, ensure adequate ventilation. 3. Remove battery.Please observe the chapter “REMOVING THE BATTERY” on Page 216.4. All vent caps should be open.The fluid level should meet the indicator mark in each cell. 5. Ensure that charger is switched off – danger of short circuit! 6. Connect charger cables.Charger cables must be connected POSITIVE (+) to POSITIVE (+) and NEGATIVE (–) to NEGATIVE (–). 7. Switch on charger.Normally, a battery should be charged at no more than 10 percent of its rated capacity. Rated capacity of the battery in your vehicle is listed on the battery housing. 8. After charging, turn off charger and disconnect charger cables. 9. Tighten the vent caps and reinstall battery Please observe the chapter “INSTALLING THE BATTERY” on Page 217. Winter operation The capacity and ability of the battery to store power decreases at low outside temperatures.Additionally, more power is consumed while start-ing, and the headlights, heater, rear window de-fogger, etc., are used more frequently. fLet your Porsche dealer test the battery’s capacity before winter sets in. The battery will discharge more quickly if your ve-hicle is not driven on a daily basis over a distance of several miles. The more often you drive your ve-hicle, and the longer the distance driven on each trip, the more opportunity the vehicle’s charging system will have to recharge the batteries.
Practical Tips, Emergency Service 215Replacing battery The service life of the battery is subject to normal wear; it depends greatly on care, climatic condi-tions, and driving conditions (distances, loads). fOnly use an original Porsche battery, with the correct part number, as a replacement. fPlease observe the disposal instructions for batteries.Putting vehicle into operationAfter the battery is connected or after an exhaus-tively discharged battery is charged, the multi-functional PSM light lights up on the instrument panel and a message appears on the on-board computer to indicate a fault.

218 Practical Tips, Emergency ServiceEmergency Starting with Jumper Cables If the battery is discharged, e.g. in winter or after the car has been parked for a long time, the bat-tery of another car can be used for starting with the help of jumper cables.Make sure the voltage of both batteries is the same. Both batteries must be 12 volt types. The capacity (Ampere hours, Ah) of the booster battery must not be substantially less than that of the discharged battery.The discharged battery must be correctly con-nected to the vehicle’s electrical system. fPlease observe the chapter “BATTERY” on Page 212.fPlease observe the chapter “EMERGENCY UN-LOCKING OF THE LUGGAGE COMPARTMENT LID” on Page 211.NotefDo not try to start the car by pushing or tow-ing. Damage to the catalytic converters and other components of the car may result. Warning!Risk of damage and serious personal injury due to short circuit. fUse only jumper cables of adequate diameter cross-section and fitted with completely insu-lated alligator clips. fFollow all warnings and instructions of the jumper cable manufacturer. fWhen connecting jumper cables, make sure that they cannot get caught in any moving parts in the engine compartment.The jumper cables must be long enough so that neither vehicles nor cables touch another. fThe vehicles must not be in contact, otherwise current might flow as soon as the positive ter-minals are connected. fThe cable clamps must not be allowed to con-tact each other when one end of the jumper ca-bles are connected to a battery. fEnsure that tools or conductive jewelery (rings, chains, watch straps) do not come into contact with the positive jumper cable or the positive battery post. fImproper hook-up of jumper cables can ruin the alternator. Danger of caustic burns. fDo not lean over the battery.Danger of gas explosion. fImproper use of booster battery to start a vehicle may cause an explosion, resulting in severe personal injuries. fKeep sources of ignition away from the bat-tery, e.g. open flame, burning cigarettes or sparking due to cable contact or welding work. fA discharged battery can freeze even at 23°F/–5°C. Before connecting jumper cables, a frozen bat-tery must be thawed out.
Practical Tips, Emergency Service 219Connect jumper cables in the following sequence: Always observe the sequence below: 1. Connect the positive lead (red) to the positive terminal of the discharged battery first, then connect it to the positive terminal of the donor battery.2. First connect the negative cable (black) to the negative terminal of the donor battery, then connect it to a suitable grounding point on the vehicle with the discharged battery. This grounding point must lie as far as possible from the battery.For example, a solid metal part or the engine block are suitable grounding points.If no suitable grounding points are to be found on either vehicle, the negative cable must carefully be connected directly to the negative terminal of the battery.If a suitable grounding point is to be found only on the donor vehicle, the negative cable must first be connected to the terminal of the discharged battery, then to the grounding point of the donor vehicle.3. Run the engine of the donor car at a higher speed.4. Start the engine.An attempted start using jumper cables should not last more than 15 seconds. Then allow a waiting period of at least one minute.NoteBefore disconnecting the jumper cables, electrical loads such as the heated rear window and the heating fan blower should be switched on (the ve-hicle’s lights must not be switched on). This reduc-es voltage peaks which may occur when discon-necting the jumper cables.With the engine running, remove both jumper ca-bles in reverse order.

The driver’s seat must be loaded by a person or a 165 lbs. (75 kg) weight and the tire pressures must meet the prescribed values. After being loaded, the car must be rolled a few meters so that the suspension can settle. For checking the headlight adjustment, the verti-cal position of the cutoff of the lowbeam (see fig.) has to be projected on a vertical screen (wall) in distance of 7.5 m (24.6 ft.) from the front lens of the headlamp.The correct position of the cutoff is 5 cm (2.0 in.) at 7.5 m or 24.6 ft. (0.4°) below a horizontal line, x cm from ground to the center of the headlamp lens. Lateral adjustment of the headlights should be carried out at a specialist workshop with an optical adjustment unit. Distance Visual aim shall be performed at not less than 7.5 m (this value is a rounded down conversion from the 25-foot distance typical of field aim using a screen). The 7.5 m (24.6 ft.) distance is meas-ured from the headlamp lens to the viewing screen. f f f
