Solution

1. Preparation

Gather necessary tools including a tire pressure gauge and an OBD-II scanner.
Park the vehicle on a level surface and ensure the engine is off.
Safety warning: Ensure the car is in "Park" mode to prevent rolling.

2. Check Tire Pressure

Use a tire pressure gauge to measure the pressure in each tire.
- Recommended pressure can be found on the driver’s side door jamb or in the owner's manual.
Inflate or deflate tires as necessary to reach the recommended pressure.

3. Inspect Tires

Visually examine each tire for:
- Punctures, cuts, or foreign objects embedded in the tread.
- Signs of sidewall damage or bulges.
Replace any damaged tires as necessary.

4. Reset TPMS

Access the vehicle settings through the touchscreen.
Navigate to the "Service" menu.
Select "Reset Tire Pressure Monitoring System" and follow the on-screen prompts.

5. Monitor and Test

After resetting, drive the vehicle for 5-10 minutes to allow the system to recalibrate.
Observe if the tire pressure warning light remains illuminated.
