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

1. Rotate the tires or replace the TPMS sensor, then adjust each tire 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) to run the relearn process.
4. Allow up to 10 minutes of driving for the relearn to finish.
5. Check the DIC, where a dash (-) or pressure value will display as the sensors are matched.

• Each TPMS sensor has a unique identification code that must be matched to its new tire/wheel position after rotation or sensor replacement.
• A warning message displays in the DIC if a problem occurs during the relearn process.
• The malfunction light and DIC message should go off once the sensor matching process is completed successfully.
