Solution

1. Preparation

Tools Required: Tire pressure gauge, air compressor, jack, jack stands, and tire repair kit (if needed).
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check and Adjust Tire Pressure

Remove valve caps from each tire.
Use a tire pressure gauge to measure the pressure of each tire.
Compare the measured pressure against the recommended pressure.
If the pressure is low, use an air compressor to inflate the tire to the correct pressure.
Recheck the pressure after inflating to confirm it is at the recommended level.
Replace the valve caps securely.

3. Inspect Tires for Damage

Examine each tire for visible damage, such as cuts, punctures, or foreign objects.
If a puncture is detected, use a tire plug or sealant to temporarily fix it, or replace the tire if damage is severe.

4. Reset TPMS

Access the vehicle's settings using the touchscreen.
Navigate to the 'Service' menu.
Select 'TPMS Reset' to reset the tire pressure monitoring system.
Confirm that the reset is successful and check if the warning light has turned off.
