Solution

1. Preparation

Ensure all tires, including the spare, are inflated to the recommended pressure (found on the driver’s door jamb).
Gather necessary tools: tire pressure gauge, vehicle's owner's manual for reference.

2. Resetting the Tire Pressure Monitoring System (TPMS)

Vehicle Positioning:
- Position the vehicle on level ground.
- Turn the ignition to the "On" position (do not start the engine).
Locate the TPMS Reset Button:
- Find the TPMS reset button, typically located beneath the steering wheel or in the glove compartment. Consult the owner’s manual for the exact location.
Press the Reset Button:
- Press and hold the TPMS reset button until the tire pressure light blinks three times, then release it.
Start the Vehicle:
- Start the engine and let it run for about 20 minutes to allow the system to recalibrate.
Verify the Reset:
- Check the dashboard to ensure the tire pressure warning light has turned off.

3. Final Inspection

After resetting, drive the vehicle for a short distance and monitor the dashboard for any warning lights.
