How to Reset the Tire Pressure Light (TPMS) on a Cadillac XT4

1. After rotating or replacing tires, set all tires to the pressure on the Tire and Loading Information label.
2. If a tire was 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) for up to 10 minutes to complete the relearn process.
4. Watch the DIC, which shows a dash (-) or pressure value during the relearn.

• Each TPMS sensor has a unique identification code that must be matched to its new tire/wheel position after rotation or sensor replacement.
• A DIC warning message displays if a problem occurs during the relearn process.
• The Maintenance menu in the vehicle info display also offers a Relearn Tire Pressure option.
