Solution

1. Preparation

Gather necessary tools: Tire pressure gauge, OBD-II scanner (if needed).
Ensure the vehicle is parked on a level surface with the engine turned off.

2. Inflate Tires

Check and adjust the tire pressure for all tires, including the spare, to the manufacturer's recommended PSI, typically found on the driver’s side door jamb.
Use a tire inflator if necessary to achieve correct pressures.

3. Reset the TPMS

Using the Vehicle's Controls:
1. Turn on the ignition without starting the engine.
2. Navigate to the "Tire Pressure" menu on the driver information center using the controls on the steering wheel.
3. Select the option to "Reset" or "Initialize" the TPMS.
4. Confirm the reset when prompted.
Using an OBD-II Scanner:
1. Connect the OBD-II scanner to the vehicle's OBD-II port.
2. Access the TPMS function on the scanner.
3. Follow the prompts to reset the TPMS.

4. Final Check

Turn off the ignition and then restart the vehicle.
Verify that the tire pressure light has turned off.
