How to Reset the Tire Pressure Light (TPMS) on a Chevrolet Avalanche

1. Set the parking brake.
2. Turn the ignition to ON/RUN with the engine off.
3. Press the RKE transmitter's Q and K buttons together for about five seconds.
4. Listen for two horn sounds and look for the TIRE LEARNING ACTIVE message on the DIC, showing relearn mode is on.

• Sensors are matched with a TPMS relearn tool in order: driver front, passenger front, passenger rear, driver rear.
• You have two minutes for the first tire and five minutes overall; otherwise the process stops and must be restarted.
• The provided pages end partway through the procedure, so the remaining steps are not shown here.
