The U.S. Department of Transportation has mandated that all vehicles manufactured after 2008 include a tire pressure monitoring system (TPMS). Although you cannot disable the TPMS in a General Motors (GM) vehicle, you can reset the system if you recently checked your tires and inflated them properly. If you do not adequately inflate the tire, however, the TPMS trouble light will remain on.
Step 1 - Start the GM vehicle.
Step 2 - Locate the lowercase "i" button on the driver's information panel. It is located to the right of the steering wheel. Press the button multiple times to access the TPMS system, and identify the specific tire that is triggering the dashboard trouble light.
Press the reset button on the driver's information panel. This button features a check mark, and is at the lower end of the panel. If this does not work, press and hold down the "i" button and then press the reset button.
