Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, and basic hand tools.
Ensure the vehicle is parked on a level surface and the tires are cold (not driven for at least three hours).

2. Inflate Tires

Remove the valve caps from each tire.
Use the tire pressure gauge to measure the current tire pressure of each tire.
If any tire is below the recommended pressure, use an air compressor to inflate it to the correct level.
- Refer to the recommended tire pressure (usually found on the door jamb).
Recheck the tire pressure after inflation to ensure it meets specifications.
Replace the valve caps securely on each tire.

3. Inspect for Damage

Examine each tire for visible signs of punctures, cracks, or bulges.
If any damage is found, consult a tire professional for repair or replacement.

4. Reset TPMS (If Necessary)

If the warning persists after inflating the tires, reset the TPMS through the vehicle's settings:
- Navigate to the "Service" menu on the touchscreen.
- Select "Reset Tire Pressure Monitoring System."
Follow the prompts to complete the reset.

5. Monitor Tire Pressure

Regularly check tire pressures (at least once a month) and before long trips.
