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

1. Set the parking brake.
2. Turn the ignition on without starting the vehicle, or put the vehicle in Service Mode.
3. In Vehicle Status on the infotainment display, touch Maintenance, then Tire Pressure.
4. Touch Relearn Tire Pressure and, if asked, touch Relearn to confirm; the horn sounds twice.
5. Use a TPMS relearn tool on each tire near the valve stem: driver front, passenger front, passenger rear, driver rear.
6. After the last horn chirps, 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.
• The manual says to reset the system after rotating tires and adjusting pressures.
