Solution

1. Preparation

Tools Required: Key fob for the vehicle, OBD-II scanner (if necessary).
Ensure the vehicle is parked on a level surface and the ignition is turned off.

2. Inflate Tires

Inflate each tire to the recommended pressure as stated on the driver’s side door jamb.
Wait a few minutes after inflating to ensure that the TPMS adjusts to the new pressure.

3. Turn On Ignition

Insert the key fob into the ignition or ensure the vehicle is in the "Run" position without starting the engine.
Press the "Start" button (if equipped) without pressing the brake pedal to power the electrical system.

4. Access TPMS Reset

Press and hold the TPMS reset button located under the steering column until the TPMS warning light blinks three times, then release the button.
If the vehicle doesn't have a dedicated reset button, proceed to the next step.

Navigate to the "Settings" menu on the dashboard display using the steering wheel controls.
Select "Vehicle" settings and look for "Tire Pressure" or similar.
Choose the option to reset or recalibrate the TPMS.

6. Drive the Vehicle

Drive the vehicle at speeds over 15 mph for approximately 10-15 minutes to allow the system to recalibrate.
Monitor the dashboard for any changes in the TPMS warning light.
