Sub-steps:
- Remove the valve caps from all four tires.
- Use a tire pressure gauge to measure the pressure in each tire.
- Inflate or deflate each tire to match the recommended pressure specified on the door jamb sticker.
- Replace the valve caps securely after adjusting pressures.

3. Inspect Tire Pressure Sensors

Sub-steps:
- Remove the tires from the wheel to access the TPMS sensors if needed.
- Inspect each sensor for physical damage, corrosion, or loose connections.
- If damaged, proceed to replace the sensors with OEM parts.

4. Reset the TPMS System

Sub-steps:
- Using the touchscreen, navigate to the settings menu.
- Select 'Service' and then 'TPMS Reset.'
- Confirm the reset and follow any on-screen instructions.

5. Final Check

Sub-steps:
- Reinstall the tires if they were removed.
- Drive the vehicle for at least 10-15 minutes to allow the system to recalibrate.
- Monitor the dashboard for any reoccurring TPMS warnings.
