Solution

1. Preparation

Tools Required: Tire pressure gauge, vehicle owner's manual
Ensure all tires are properly inflated to the recommended PSI.
Ensure the vehicle is parked on a level surface.

2. Resetting the TPMS

Locate the TPMS reset button:
- Find the TPMS reset button, usually located under the steering wheel or near the fuse box.
Press and hold the TPMS reset button:
- Hold the button until the tire pressure light blinks three times, then release it.
Turn on the ignition:
- Turn the ignition to the "Run" position (do not start the engine). The light should remain illuminated for a few seconds and then turn off.
Drive the vehicle:
- Drive the vehicle for at least 10 minutes at speeds above 15 mph to allow the TPMS to recalibrate.

3. Final Check

After driving, check to see if the tire pressure light has turned off. If it remains illuminated, recheck tire pressures and repeat the reset process if necessary.
