Solution

1. Preparation

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

2. Adjust Tire Pressure

Check Tire Pressure:
- Use a tire pressure gauge to measure the air pressure in each tire.
- Note down the pressures for comparison.
Inflate Tires:
- If any tire is under-inflated, use an air compressor to fill it to the recommended pressure as indicated on the door jamb.
- Repeat for all tires as necessary.
Inspect for Leaks:
- If a tire consistently loses pressure, inspect for punctures or leaks.
- If found, mark the area for repair or replacement.

3. Reset TPMS

Vehicle Settings:
- Access the vehicle’s display and navigate to the settings menu.
- Look for the tire pressure monitoring system settings.
TPMS Reset:
- Follow the prompts to reset the TPMS.
- Ensure that the vehicle is stationary during the reset process.
