- Inflate or deflate tires to the recommended pressure specified on the driver’s door jamb.
- Recheck the pressure after adjustments.

2. TPMS Sensor Inspection

Visual Inspection:
- Remove the tire from the wheel if necessary to check the TPMS sensor for damage.
- Inspect the valve stem for leaks or cracks.
Sensor Testing:
- Use a TPMS tool to activate each sensor and ensure they are functioning correctly.
- Replace any faulty TPMS sensors.

3. TPMS System Reset

Reset the TPMS:
