Solution

1. Preparation

Gather necessary tools: Tire pressure gauge, OBD-II scanner (if needed).
Ensure the vehicle is parked on a level surface and the engine is turned off.
Check the recommended tire pressure found on the driver’s side door jamb or in the owner's manual.

2. Check Tire Pressure

Remove the valve caps from all tires.
Use the tire pressure gauge to measure the pressure in each tire.
Inflate or deflate tires as needed to match the recommended pressure.
Reinstall the valve caps securely.

3. Reset the TPMS

Turn on the ignition without starting the engine.
Press the accelerator pedal three times within 10 seconds.
Turn off the ignition.
Start the engine and drive the vehicle for a few minutes to allow the TPMS to recalibrate.

4. Verify the Reset

Turn off the engine and restart it to check if the tire pressure light has turned off.
If the light remains illuminated, recheck tire pressures and repeat the reset procedure.
