Solution

1. Preparation

Gather required tools: digital tire pressure gauge, air compressor, OBD-II scanner, and a tire repair kit if necessary.
Safety warning: Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Inspect Tires

Check each tire for visible signs of damage such as cuts, bulges, or foreign objects.
Confirm that the valve stems are not leaking.

3. Measure Tire Pressure

Use the digital tire pressure gauge to check the pressure of all four tires.
Refer to the manufacturer's recommended tire pressure, usually found on a sticker inside the driver’s door jamb.

4. Inflate Tires

If any tire is below the recommended pressure, use an air compressor to inflate it to the correct level.
Check pressure again after inflation to ensure accuracy.

5. Reset TPMS

Navigate to the settings on the touchscreen.
Locate the TPMS section and select the option to reset or recalibrate the system.
Monitor the warning light for re-illumination.

6. Repair or Replace (if necessary)

If damage is found, repair the tire using a tire repair kit or replace the tire if the damage is severe.
Ensure the replacement tire matches the specifications of the original tires.
