Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, and TPMS reset tool (if applicable).
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check and Adjust Tire Pressure

Sub-steps:
- Remove the valve stem cap from each tire.
- Use the tire pressure gauge to measure the current tire pressure.
- Compare the readings with the recommended tire pressure (found in the owner's manual or on the driver’s door jamb).
- Inflate tires to the recommended pressure using an air compressor.
- Recheck the tire pressure to ensure it is accurate.

3. Inspect Tires

Sub-steps:
- Examine each tire for visible damage, such as cuts, punctures, or bulges.
- Look for uneven wear patterns, which may indicate alignment or suspension issues.
- If damage is found, consider replacing the tire or consulting a professional.

4. Reset TPMS

Sub-steps:
- Access the vehicle’s touchscreen interface.
- Navigate to the "Service" menu and select "Tire Pressure Monitoring."
- Follow the prompts to reset the TPMS after adjusting tire pressures.

5. Test Drive

Sub-steps:
- Drive the vehicle for about 10-15 minutes to allow the system to recalibrate.
- Monitor the dashboard for any warning lights during the drive.

Tools Required:

Tire pressure gauge
Air compressor
TPMS reset tool (if applicable)
