The tire pressure monitoring system alerts the driver when there is a large change in the air pressure of one tire. The system learns the air pressure at each tire throughout the operating speed range of the vehicle, and compares tire rotational speeds using the antilock brake system's wheel speed sensors. The tire pressure monitoring system will not alert the driver before driving the vehicle that a tire is low or flat. The driver must begin driving the vehicle before the system will work properly.

The CHECK TIRE PRESSURE warning message, on the driver information center (DIC), and the tire pressure warning light, on the instrument panel cluster, will illuminate f the system detects a pressure difference in one of the four tires installed on the vehicle. For additional information and details about the DIC operation and displays refer to Indicator/Warning Message Description and Operation and Driver Information Center (DIC) Description and Operation .

The tire pressure monitoring system may not warn the driver of a tire pressure condition if :

If the tire pressure warning light illuminates and the CHECK TIRE PRESSURE message is displayed on the DIC, measure the air pressure in all four tires and adjust or repair if necessary. Refer to Tire Inflation Description and Vehicle Certification, Tire Placard, Anti-Theft, and Service Parts ID Label .

The tire pressure monitoring system does not set any diagnostic trouble codes (DTCs).

If tire pressure is adjusted or one or more tires is repaired, replaced, or rotated, the tire pressure monitoring system must be reset.

To reset the tire pressure monitoring system:

1. Turn the ignition switch to RUN, with the engine off.
2. Press the vehicle information button on the DIC until the PRESS Set/Reset TO RESET TIRE SYSTEM message appears on the display.
3. Press and hold the DIC Set/Reset button for five seconds. After five seconds, the display will show TIRE PRESSURE SYSTEM RESET.

The system completes the calibration process during driving. The system learns the pressure at each tire throughout the operating speed range of your vehicle. The system normally takes between 20 and 45 minutes of driving in each of the following speed ranges to learn tire pressures: 25 to 40 mph (40 to 64 km/h), 40 to 60 mph (64 to 96 km/h), and 60 to 85 mph (96 to 136 km/h). This time may be longer depending on individual driving habits. Learning need not be accumulated during a single trip. Once learned, the system will remember the tire pressures until the system is reset.
