Tire Pressure Monitoring System

The Tire Pressure Monitor System (TPMS) uses radio and sensor technology to check tire pressure levels. TPMS sensors monitor the air pressure in the tires and transmit tire pressure readings to a receiver located in the vehicle.

Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the tire 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 correct tire pressure for those tires.)

As an additional safety feature, your vehicle has been equipped with a Tire Pressure Monitor System (TPMS) that illuminates a low tire pressure warning light when one or more of your tires is significantly underinflated.

Therefore, when the low tire pressure warning light illuminates, you should stop and check your tires as soon as possible and inflate them to the proper pressure. Driving on a significantly underinflated tire causes the tire to overheat and can lead to tire failure. Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability.

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 underinflation has not reached the level that triggers the TPMS low tire pressure warning light.

Your vehicle has also been equipped with a TPMS malfunction indicator to signal when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure warning light. When the system detects a malfunction, the indicator will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists.

When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction indicator after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly.
