Pontiac G8 manual Tpms Malfunction Light and Message

9-52 Vehicle Service and Care

The vehicle’s TPMS system can warn about a low tire pressure condition but it does not replace normal tire maintenance. See Tire Inspection and Rotation on page 9-54and Tires on page 9-39.

Notice: Using non-approved tire sealants could damage

the Tire Pressure Monitor System (TPMS) sensors. TPMS sensor damage caused by using an incorrect tire sealant is not covered by the vehicle warranty. Always use the GM approved tire sealant available through your dealer/retailer.

TPMS Malfunction Light and Message

The TPMS will not function properly if one or more of the TPMS sensors are missing or not operating.

When the system detects a malfunction, the 7 low tire warning light flashes for about one minute and then stays on for the remainder

of the ignition cycle. A DIC warning message also displays. The low tire warning light and DIC warning message come on at each ignition cycle until the problem is corrected. Some of the conditions that can cause the malfunction light and DIC message to come on are:

•One of the road tires has been replaced with the spare tire. The spare tire does not have a TPMS sensor. The TPMS malfunction light and DIC message should go off once the road tire containing the TPMS sensor is re-installed.

•The TPMS sensor matching process was started but not completed or not completed successfully after installing replacement tires or rotating the vehicle’s tires. The DIC message and TPMS malfunction light should go off once the TPMS sensor matching process is performed successfully.

•One or more TPMS sensors are missing or damaged. The DIC message and the TPMS malfunction light should go off when the TPMS sensors are installed and the sensor matching process is performed successfully. See the dealer/ retailer for service.

•Replacement tires or wheels do not match the vehicle’s original equipment tires or wheels. Tires and wheels other than those recommended for the vehicle could prevent the TPMS from functioning properly. See Buying New Tires on page 9-56.

•Operating electronic devices or being near facilities using radio wave frequencies similar to the TPMS could cause the TPMS sensors to malfunction.
