Solution

1. Preparation

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

2. Check and Adjust Tire Pressures

Check Tire Pressures
- Use a tire pressure gauge to measure the pressure of all four tires.
- Note the readings and compare them to the recommended psi listed on the driver’s side door jamb.
Inflate Tires if Necessary
- If any tire is below the recommended psi, use an air compressor to inflate it to the correct pressure.
- Recheck with the tire pressure gauge to ensure accuracy.

3. Reset Tire Pressure Monitoring System

Access the Touchscreen
- Power on the vehicle and go to the main touchscreen interface.
Navigate to Tire Pressure Settings
- Tap on ‘Controls’, then ‘Service’, and locate the ‘Tire Pressure’ section.
Reset the TPMS
- Select the option to reset or recalibrate the tire pressure monitoring system.
- Follow any on-screen prompts to complete the reset.

4. Verify Reset

Once the reset is done, observe the dashboard for any re-illuminated warning lights to ensure the TPMS is functioning correctly.
