Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor (if needed), OBD-II scanner, and TPMS reset tool (if applicable).
Ensure the vehicle is on a flat surface and the tires are cold (preferably before driving).

2. Check and Inflate Tires

Remove valve caps from each tire.
Use the tire pressure gauge to measure the pressure in each tire.
Refer to the vehicle’s door jamb for the recommended tire pressure.
If any tire is below the recommended pressure, use an air compressor to inflate it to the proper level.
Replace valve caps securely after checking.

3. Inspect and Repair (if necessary)

If any tire shows signs of damage, inspect further for punctures or leaks.
If a puncture is found, either repair with a tire plug kit or replace the tire as necessary.
Check for any bent rims or other issues that may affect tire pressure.

4. Reset TPMS

Turn on the vehicle and navigate to the settings menu on the touchscreen.
Locate the TPMS reset option and select it.
Follow on-screen prompts to complete the reset process.
Confirm that the TPMS warning light is no longer illuminated.
