How to Reset the Tire Pressure Light (TPMS) on a GMC Sierra 1500 Limited

1. Set the parking brake and turn the ignition on without starting the vehicle.
2. Scroll to the Tire Pressure screen on the DIC info page using the DIC controls or the trip odometer reset stem.
3. Press and hold the thumbwheel, or hold the reset stem about five seconds and select yes, to start relearn mode; the horn sounds twice.
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; the horn sounds twice when done.
6. 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.
• On uplevel DIC, make sure the Tire Pressure info page option is turned on in the Options menu.
• A TPMS relearn tool is needed; see your dealer or GM tools to purchase one.
