Solution

1. Preparation

Ensure that the vehicle is parked on a flat surface and the engine is turned off.
Gather necessary tools: tire pressure gauge, OBD-II scanner (if needed).

2. Inflate Tires

Use a tire inflator to adjust tire pressures if they are below the recommended levels.
- Check each tire, including the spare if equipped with TPMS.
- Inflate tires to the specified pressure (usually found on the driver's door jamb).

3. Reset TPMS

Turn the ignition switch to the "ON" position without starting the engine.
Locate the TPMS reset button, usually found beneath the steering column or in the glove compartment.
Press and hold the TPMS reset button until the tire pressure light blinks three times, then release it.
Start the engine and wait for about 20 minutes for the system to recalibrate and confirm the reset.

4. Verify Operation

After the reset, check that the tire pressure light turns off.
Drive the vehicle for a short distance to ensure that the system has successfully recalibrated.
