How to Reset the Tire Pressure Light (TPMS) on a GMC Savana

Steps from the 2026 GMC Savana owner's manual (Relearn using a TPMS relearn tool; RKE button method for vehicles with RKE, DIC method for vehicles without RKE).

Set the parking brake and turn the ignition on without starting the vehicle.
Press the RKE transmitter's Q and K buttons together for about five seconds until the horn sounds twice and TIRE LEARNING ACTIVE shows.
Hold the relearn tool against the driver side front tire sidewall near the valve stem and press its button until the horn sounds once.
Repeat the same step at the passenger side front, passenger side rear, then driver side rear tires.
After the horn sounds twice for the last tire, turn the vehicle off and set all four tires to the pressure on the Tire and Loading Information label.

You have two minutes for the first tire and five minutes overall, or the process stops and must be restarted.
Without RKE, press the DIC vehicle information button until PRESS reset TO RELEARN TIRE POSITIONS displays.
