The Tire Pressure Monitor (TPM) System on your vehicle, uses radio and sensor technology to check tire pressure levels. Sensors, mounted on each tire and wheel assembly transmit tire pressure readings to a receiver located in the vehicle. The TPM sensors transmit tire pressure readings once every 60 seconds while the vehicle is being driven and once every 60 minutes when the vehicle is stationary for more than 15 minutes. Using the Driver Information Center (DIC), tire pressure levels can be viewed by the driver. The TPM system also uses the DIC to warn the driver when air pressure, in one or more tires, falls below 25 psi (172 kPa) or is above 38 psi (262 kPa). For additional information and details about the DIC operation and displays see DIC Controls and Displays and DIC Warnings and Messages .

A low tire warning light also appears on the instrument panel cluster when a low tire condition exists. The DIC message, CHECK TIRE PRESSURE and the low tire pressure warning light will be shown each time the engine is started and stay on until the low tire condition is corrected.

When the tire pressure monitoring system warning light is lit, one or more of your tires is significantly under-inflated.

You should stop and check your tires as soon as possible, and inflate them to the proper pressure as indicated on the vehicle's tire information placard.

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. Each tire, including the spare, should be checked monthly when cold and set to the recommended inflation pressure as specified in the vehicle placard and owner's manual.

The Tire and Loading Information Label (tire information placard) is either on the rear edge of the driver's door or the driver's door jamb near the latch. This label shows the size of your vehicle's original tires and the correct inflation pressure for your vehicle's tires when they are cold. See Inflation - Tire Pressure .

Your vehicle's TPM system can alert you about a low or high tire pressure condition but it does not replace normal tire maintenance. See Tire Inspection and Rotation

Each TPM sensor has a unique identification code that is matched to one of the four tire positions on your vehicle. The tire and wheel assembly positions are, left front (LF); right front (RF); right rear (RR) and left rear (LR). Any time you rotate your vehicle's tires or replace one or more TPM sensors, the identification codes will need to be matched to the new tire and wheel position. The TPM matching process is performed in a specific sequence and time limit. A special tool is also required. See your dealer for service.

The SVC TIRE MONITOR message is displayed when the TPM system is malfunctioning. For example, one or more TPM sensors may be inoperable or missing. See your dealer for service.
