Solution

1. Preparation

Gather all tools and components needed for the procedure.
Ensure the vehicle is parked on a flat, stable surface.
Safety warning: Always use caution when working with tires and maintain proper lifting techniques.

2. Check and Adjust Tire Pressure

Remove Valve Caps: Unscrew and remove the valve caps from each tire.
Measure Tire Pressure: Use a tire pressure gauge to check the pressure of each tire.
- Compare the measured pressure with the recommended pressure.
Inflate Tires: If any tire is below the recommended pressure, use an air compressor to inflate it to the correct level.
- Check again with the gauge to ensure accuracy.
Replace Valve Caps: After adjusting, securely replace the valve caps on all tires.

3. Inspect for Damage

Visual Inspection: Examine each tire for any visible damage, such as cuts, punctures, or bulges.
Check for Leaks: If a tire appears to be losing air, apply soapy water to the tire surface to identify any bubbles indicating a leak.
Repair or Replace: Repair punctured tires as necessary or replace tires that are damaged beyond repair.

4. Reset TPMS

Turn on Ignition: Start the vehicle and allow all systems to initialize.
Access TPMS Menu: Navigate to the tire pressure monitoring section on the vehicle's display.
Select Reset: Follow the prompts to reset the TPMS after ensuring all tires are at the correct pressure.
Confirm Reset: Wait for the confirmation message indicating that the TPMS has been reset.
