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

1. Rotate the tires or replace the sensor, then set the tires to the pressure on the Tire and Loading Information label.
2. After installing a tire, keep the vehicle stationary for about 20 minutes so the system can recalculate.
3. Drive at a minimum speed of 20 km/h (12 mph) for up to 10 minutes so the relearn can finish.
4. Watch the DIC, which shows a dash (-) or pressure value during the relearn.

• The manual describes only an automatic relearn, with no button or menu reset.
• A DIC warning message appears if a problem occurs during the relearn.
• The malfunction light and DIC message should go off once the sensor matching process succeeds.
