Notice System Scope of Use and Warnings ɎSystem Installation and UsageUse of the TPMS requires that qualified personnel according to the instructions here have properly installed it.This system is suitable for use on a passenger car, SUV and 4X4 tires.TPMS can monitor and provide tire pressure and tire temperature in real time to help the driver control and keepthe normal tire pressure in order  to reduce the fuel consumption and extend the tire life, and also reduce thepossibility of vehicle breakdown on the road or heavy incident or crash to occur.ɎReacting to AlertsWhen an alert or warning is received, reduce vehicle’s speed and proceed to a safe location to stop where the tirecan be inspected and /or serviced.The low-pressure alert indicates that the air pressure has dropped to a selected minimum and a high-temperaturealert indicates that the temperature of the tire content has surpassed the threshold value set.Caution The system is a wireless RF product; therefore, it may not receive a signal due to poor environmental conditions or incorrect  installation. When the system continuously cannot receive any signal from any tire sensor for more than 10 minutes since the system has been switch on, the display will show “ERROR” and activate the alert sound. In this case, a RF interference environment may have caused it; a driver will need to drive the vehicle to a different location. If the display is still unable to receive any correct signal from tire sensor, the driver will need to find a nearby qualifiedtire maintenance service to check or carry out maintenance. This abnormality may be caused by a damaged tire sensor or excessive battery power consumption.   2
