How to Reset the Tire Pressure Light (TPMS) on a Buick Encore GX

1. Set the parking brake.
2. Turn the ignition on without starting the vehicle, or place the vehicle in Service Mode.
3. On the infotainment display, open Vehicle Status, touch Maintenance, then touch Tire Pressure.
4. Touch Relearn Tire Pressure, and touch Relearn if asked to confirm. Two audible alerts and RELEARNING TIRE PRESSURE show the receiver is in relearn mode.
5. Press 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. After two alerts confirm the driver side rear tire, 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.
• A single audible alert confirms each sensor was matched to its tire position.
