260Driving systemsTechnicaldataInstruments and controls Operation Driving Instrument cluster display Practical hints Car care IndexDistronic (DTR)(optional)When activated the Distronic system increases driving convenience, for example over long distances, as it automatically maintains a speed set by the driver by actively regulating the throttle setting. It also maintains within certain limitations a preset distance to a vehicle ahead.With Distronic switched off, the multifunction display continues to show the distance to the vehicle ahead, if so selected, see page 274. The distance warning function can be activated separately, see page 271.In Distronic mode, if the distance sensor detects a slower moving vehicle directly ahead, your vehicle speed will be reduced to the extent permitted by reduced throttle and up to 20% of vehicle braking power, so that you follow that vehicle at a preset distance, see page 272.Maximum range of detection is approximately 500 ft. (150 m).Any given speed between 25 mph (Canada: 30 km/h) and 110 mph (Canada: 180 km/h) can be maintained with the Distronic by operating the control lever on the steering column.Warning!Distronic is a convenience system, its speed adjustment reduction capability is intended to make cruise control more effective and usable when traffic speeds vary. It is not, however, intended to nor does it replace the need for extreme care. The responsibility for the vehicle speed and the distance to the vehicle ahead, including most importantly brake operation to assure safe stopping distance, rests always with the driver.Warning!Distronic requires familiarity with its operational characteristics. We strongly recommend that you review the following information carefully before operating the system.part3_01.fm Seite 260 Montag, 7. Mai 2001 7:05 07

264Driving systemsTechnicaldataInstruments and controls Operation Driving Instrument cluster display Practical hints Car care Index•For a more precise setting the speed can be increased in increments of 1 mph (Canada: 1 km/h) by briefly pulling the control lever in direction (4).Caution!If the driver’s foot is not fully removed from the accelerator pedal, the message “DISTRONIC OVERRIDE” appears in the multifunction display. The Distronic control system will be overridden and it will not regulate the preset vehicle speed and following distance. The vehicle speed and following distance will be determined only by the accelerator pedal position.Invalid attempts to activateThe multifunction display will show “––– MPH” during invalid attempts to activate Distronic:•below a speed of approximately 25 mph (Canada: 30 km/h),•while the electronic stability program (ESP) is switched off – ESP warning lamp v in speedometer dial is illuminated, see page 112, •by moving the distronic control lever in “RESUME” direction (4) when no speed is stored in memory,•during the initialization and self-test phase after the engine is started – this can take up to 2 minutes,•while depressing the service brake pedal,•while the parking brake is set – check ;warning lamp (Canada: !) in instrument cluster, see page 112,•with the gear selector lever in position “P”, “R” or “N” – check gear range indicator display in instrument cluster, see page 112.See page 330 for malfunction and warning messages if the Distronic is malfunctioning.Warnin g!Distronic brakes (up to 20% of vehicle braking power) the vehicle to restore the preset distance or to maintain the speed. The brake pedal is automatically retracted as this happens.Keep driver’s foot area clear at all times, including the area under the brake pedal. Objects stored in this area may impair pedal movement which could interfere with the braking ability of the Distronic system.Do not place your foot under the brake pedal – your foot could become caught.part3_01.fm Seite 264 Montag, 7.

265Driving systemsTechnicaldataInstruments and controls Operation Driving Instrument cluster display Practical hints Car care IndexDeactivation of DistronicBriefly move the distronic control lever in “OFF” direction (3) – the stored speed remains in the memory until the electronic key in the starter switch is turned to position 1 or 0.Distronic is also deactivated if:•the service brake pedal is depressed, •the parking brake is activated,•the vehicle decelerates to less than approximately 25 mph (Canada: 30 km/h), e.g. while maintaining the distance to the vehicle ahead,•the gear selector lever is moved to position “N”,•the electronic stability program (ESP) is active,•the electronic stability program (ESP) is switched off manually.Note:A signal sounds and the message “DISTRONIC OFF” appears for 5 seconds in the multifunction display everytime Distronic is deactivated (except when moving distronic control lever in “OFF” direction).Warnin g!The Distronic switches off and releases the brakes when the vehicle decelerates below the minimum speed of 25 mph (Canada: 30 km/h) by operation of the system. At that time, the driver must apply the brakes in order to reduce vehicle speed further or bring it to a stop.part3_01.fm Seite 265 Montag, 7. Mai 2001 7:05 07
266Driving systemsTechnicaldataInstruments and controls Operation Driving Instrument cluster display Practical hints Car care IndexDriving with Distronic activatedWith the electronic key in starter switch position 2, the distance warning lamp l in the speedometer dial comes on and goes out with the engine running.If the distance sensor detects a slower vehicle moving in front, your vehicle speed will be reduced by deceleration and braking of up to 20% of the vehicle braking capacity, so that you follow the vehicle ahead at the preset distance, see page 272. Segments in the speedometer illuminate to indicate the speed range from the speed of the vehicle in front up to your vehicle’s selected speed. See also page 274 for notes on the multifunction displays.Warning!Distronic brakes (up to 20% of vehicle braking power) the vehicle to restore the preset distance or to maintain the speed. The brake pedal is automatically retracted as this happens.Keep driver’s foot area clear at all times, including the area under the brake pedal. Objects stored in this area may impair pedal movement which could interfere with the braking ability of the Distronic system.Do not place your foot under the brake pedal – your foot could become caught.part3_01.fm Seite 266 Montag, 7.

267Driving systemsTechnicaldataInstruments and controls Operation Driving Instrument cluster display Practical hints Car care IndexThe distance warning sound continues until the driver activates the brake pedal, or the preset distance is obtained. As soon as the preset distance is obtained, the distance warning lamp goes out.Caution!If the driver’s foot is not fully removed from the accelerator pedal, the message “DISTRONIC OVERRIDE” appears in the multifunction display. The Distronic control system will be overridden and it will not regulate the preset vehicle speed and following distance. The vehicle speed and following distance is determined only by the accelerator pedal position.Distronic works on steep uphill and downhill gradients by downshifting gears and applying the brakes to maintain the speed selected by the driver. The transmission will upshift again once the gradient evens out.The speed can be increased (e.g. for passing) by using the accelerator. After the accelerator is released, the previously set speed will be resumed automatically.Distronic is deactivated if a vehicle in front causes your vehicle to slow down to less than approximately 25 mph (Canada: 30 km/h). A signal sounds and the message “DISTRONIC OFF” appears for 5 seconds in the multifunction display.The vehicle speed displayed can briefly vary from the speed setting of the Distronic system.Warnin g!An intermittent warning sounds and the distance warning lamp in the speedometer dial is illuminated if the Distronic system calculates that the distance to the vehicle ahead and your vehicle’s current speed indicate that Distronic will not be capable of slowing the vehicle sufficiently to maintain the preset following distance, which creates a danger of a collision.Immediately brake the vehicle to increase the distance to the vehicle in front of you. The warning sound is intended as a final caution that you have not interceded with your own braking inputs to avoid a potentially dangerous situation. Do not wait for the operation of the warning signal to intercede with your own braking as that will result in potentially dangerous emergency braking which will not always result an impact being avoided.Tailgating increases the risk of an accident.part3_01.fm Seite 267 Montag, 7.

268Driving systemsTechnicaldataInstruments and controls Operation Driving Instrument cluster display Practical hints Car care IndexAdditional driving hintsImportant!When starting the engine, Distronic goes through an initialization and self-test phase – this can take up to 2minutes. The most likely cause for a malfunctioning system is caused by a dirty sensor (located behind the hood grille), especially at times of snow and ice or heavy rain. In such a case, Distronic will switch off, and the message “DISTRONIC – CLEAN SENSOR!” appears in the multifunction display.For cleaning and care of the Distronic sensor, see page 385.Restart the engine after cleaning the sensor.The following are some sample situations which may influence the functions of Distronic.Warnin g!Distronic works to maintain the speed selected by the driver unless a moving obstacle proceeding directly ahead of it in the same travel direction is detected (e.g. following another vehicle ahead at a distance set by Distronic). This means that:• your vehicle can pass another vehicle after you change lanes,• while in a sharp turn or if the vehicle in front is in a sharp turn, Distronic could lose sight of a vehicle traveling in front of it, then your vehicle could accelerate to the previously selected speed.Distronic regulates only the distance between your vehicle and those directly ahead, but does not register stationary objects in the roadway, e.g.: • a stopped vehicle in a traffic jam,• a disabled vehicle,• an oncoming vehicle.The driver must always be on the alert and observe all traffic and intercede with steering and braking inputs as necessary.Warning!Distronic should not be used in snowy or icy road conditions.part3_01.fm Seite 268 Montag, 7. Mai 2001 7:05 07
269Driving systemsTechnicaldataInstruments and controls Operation Driving Instrument cluster display Practical hints Car care IndexTraveling through turns or bends in the roadway may result in Distronic detecting a moving vehicle traveling in front but not in your lane of travel, causing your vehicle to brake late or unexpectedly. You must be prepared to intercede with accelerator or brake application as necessary.The Distronic system’s detection zone is relatively narrow at the start and becomes broader as it senses further from the vehicle. Thus, Distronic may not recognize another vehicle coming into your path close to the front of your vehicle. You must be prepared to intercede with braking or steering as necessary. A vehicle not traveling directly in front of you could cause detection problems, the actual distance to that vehicle really being much shorter.part3_01.fm Seite 269 Montag, 7. Mai 2001 7:05 07
270Driving systemsTechnicaldataInstruments and controls Operation Driving Instrument cluster display Practical hints Car care IndexA vehicle changing lanes at close range is only recognized when entering the area scanned by Distronic. You must apply the service brakes to gain sufficient distance to the vehicle ahead.A narrow vehicle (e.g. a motorcycle) is only recognized when entering the area scanned by Distronic. You must apply the service brakes to gain sufficient distance to the vehicle ahead.P54.70-2164-26part3_01.fm Seite 270 Montag, 7. Mai 2001 7:05 07
271Driving systemsTechnicaldataInstruments and controls Operation Driving Instrument cluster display Practical hints Car care IndexDistance warning functionEven if Distronic is deactivated, the distance to the vehicle ahead continues to be measured, see page 274 for multifunction display.The Distronic lamp in the speedometer dial illuminates to advise the driver of a situation which under normal braking conditions and dry surfaces should have been addressed by the driver.The distance warning function can be activated separately, see page 271. It operates when driving at speeds above approximately 25 mph(Canada: 30 km/h).When recognizing a stationary obstacle or a slower vehicle moving in the vehicle’s path and the danger of a collision exists, the distance warning lamp in the speedometer dial lights up and simultaneously an intermittent warning sounds.When pressing the brake pedal, the warning sound stops. The warning sound also stops, when the distance to the vehicle ahead is sufficient again without applying the brake pedal. In this case the distance warning lamp also extinguishesImportant!With the Distronic switched off, only the distance warning function operates, meaning the vehicle does not slow down.Distronic does not register oncoming vehicles. Therefore there is no distance warning.Important!Complex driving situations are not always fully recognized by Distronic, which could result in wrong or missing distance warnings. See page 268 for additional driving hints.Warning!If the distance warning lamp in the speedometer dial lights up while driving and an intermittent warning sounds, immediate attention on the part of the driver is required.As required by the traffic situation, apply the service brakes and navigate around a possible obstacle. However, do not drive by relying on the distance warning function as that will result in an emergency braking application which, especially depending on road surface conditions and driver reaction, will not always be able to avoid a collision.part3_01.fm Seite 271 Montag, 7.
