Solution

1. Preparation

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

2. Check and Adjust Tire Pressure

Remove the valve stem caps from all tires.
Use the tire pressure gauge to measure the pressure in each tire.
If any tire pressure is low, use an air compressor to inflate the tire to the recommended pressure.
Recheck the tire pressure after inflation to ensure it is correct.
Replace the valve stem caps securely.

3. Reset the TPMS

Power on the vehicle by pressing the brake pedal (do not start the engine).
On the touchscreen, navigate to the 'Service' menu.
Select 'Tire Pressure Monitoring' or 'TPMS Reset'.
Follow the on-screen prompts to reset the TPMS.
A confirmation message should appear once the reset is successful.
