Solution

1. Preparation

Gather necessary tools: tire pressure gauge, OBD-II scanner (if needed).
Ensure the vehicle is parked on a flat surface and turned off.
Confirm all tires are at the recommended pressure (refer to the sticker located on the driver’s side door jamb).

2. Resetting the Tire Pressure Monitoring System

Turn on the Ignition: Insert the key and turn it to the "ON" position without starting the engine.
Locate the TPMS Reset Button: This is typically found under the steering wheel or near the instrument panel.
Press and Hold the TPMS Reset Button: Hold the button until the tire pressure light blinks three times, then release it. This may take about 3-5 seconds.
Start the Engine: Turn the ignition to the "START" position and allow the vehicle to run for a few minutes.
Check the Dashboard Light: The tire pressure warning light should turn off if the reset was successful.

3. Final Checks

After resetting, recheck the tire pressures to ensure all are at the recommended levels.
Test drive the vehicle to confirm that the TPMS warning light remains off.
