How to Reset the Tire Pressure Light (TPMS) on a Cadillac CELESTIQ

1. Rotate the tires or replace a TPMS sensor, since each sensor's identification code must be matched to its new position.
2. If a tire was just installed, 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) to run the relearn process, which takes up to 10 minutes.
4. Watch the DIC, which shows a dash (-) or a pressure value during the relearn.
5. Check the DIC for a warning message, which appears if a problem occurs during the relearn process.

• After a rotation, set the tires to the pressure on the Tire and Loading Information label.
• The TPMS malfunction light and DIC message should go off once the sensor matching process succeeds.
• If equipped, reset the Tire Rotation counter only after the rotation is finished, using Vehicle Status then Tire Rotation.
