Solution

1. Preparation

Gather tools: tire pressure gauge, air compressor (if needed), and a TPMS reset tool (if required).
Ensure the vehicle is parked on a level surface and the tires are cool to the touch.

2. Check Tire Pressure

Use a tire pressure gauge to measure the current pressure of each tire.
Compare the readings to the recommended tire pressure specified on the driver’s side door jamb.

3. Inflate or Deflate Tires

If the pressure is below the recommended level, use an air compressor to inflate the tires to the correct pressure.
If the pressure is above the recommended level, release some air until the correct pressure is achieved.
Recheck the pressure with the gauge.

4. Inspect Tires

Examine each tire for visible damage such as cracks, bulges, or foreign objects embedded in the tread.
If any damage is found, replace the tire as needed.

5. Reset TPMS

Access the vehicle's settings via the touchscreen.
Navigate to ‘Service’ and select ‘Reset Tire Pressure Monitoring System.’
Follow the prompts to complete the reset.
