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

1. Set the parking brake.
2. Turn the ignition on without starting the vehicle, or place it in Service Mode.
3. Uplevel DIC: select Tire Pressure from the vehicle status menu, touch Maintenance, then Tire Pressure, then Relearn Tire Pressure, and confirm with Relearn if asked.
4. Base Level DIC: scroll to the Tire Pressure screen, hold the trip odometer reset stem about five seconds, then select yes and confirm.
5. Hold the relearn tool against each tire sidewall near the valve stem and press its button, in this order: driver front, passenger front, passenger rear, driver rear.
6. Wait for the horn chirp at each tire, then turn the vehicle off and set all four tires to the pressure on the Tire and Loading Information label.

• You have two minutes to match the first tire and five minutes overall for all four, or the process must be restarted.
• Do this after rotating tires or replacing TPMS sensors, or after swapping a spare for a road tire with a sensor.
• The horn sounds twice when relearn mode starts.
