How to Reset the Tire Pressure Light (TPMS) on a Chevrolet Sonic

1. Set the parking brake and turn the ignition on without starting the vehicle, or use Service Mode.
2. Press MENU and use the thumbwheel to scroll to Tire Learn (base DIC) or Tire Pressure (uplevel DIC).
3. Press and hold SET/CLR until the horn sounds twice, showing relearn mode is active.
4. Hold the relearn tool against the driver side front tire sidewall near the valve stem and press its button until the horn chirps.
5. Repeat at the passenger side front, passenger side rear, then driver side rear tire.
6. After two horn sounds, turn the vehicle off and set all four tires to the pressure on the Tire and Loading Information label.

• You have two minutes for the first tire and five minutes overall, or the process stops and must be restarted.
• Needed after rotating tires or replacing TPMS sensors or a spare tire with a road tire containing a sensor.
