If tire pressure is too low in one or more tires, the system will inform the driver via the warning light in the instrument panel and by the warning beep sound. The tire pressure sensors installed on each wheel send tire pressure data by radio signal to the receiver unit in the vehicle. TPMS does not alleviate your need to check the pressure and condition of all four tires before you drive each day. CAUTION l Tire pressure sensors NOTE When the ambient temperature is low due to seasonal changes, tire temperatures are also lower. If the tire temperature lowers, the air pressure lowers as well, and the TPMS warning light illuminates more frequently. Inspect the tire pressure daily before driving, and check the tire pressures monthly with a tire pressure gauge. When checking the tire pressures, use of a digital tire pressure gauge is recommended. Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale. 5-26 í Some models.
