Solution

1. Tire Pressure Adjustment

Sub-steps:
- Remove the valve cap from the tire with low pressure.
- Use an air compressor to inflate the tire to the recommended PSI (found on the driver’s door jamb).
- Recheck the pressure with the gauge to ensure it is within specifications.
- Replace the valve cap securely.

2. Tire Inspection and Repair

Sub-steps:
- Visually inspect the tire surface for punctures or foreign objects.
- If a puncture is found, use a tire repair kit to seal the puncture or take the tire to a professional for repair.
- If damage is significant (e.g., sidewall damage), replace the tire with a new one.

3. TPMS Sensor Check

Sub-steps:
- Remove the tire from the wheel if necessary to access the TPMS sensor.
- Inspect the sensor for any corrosion or physical damage.
- If the sensor is faulty, replace it with a new TPMS sensor compatible with the Tesla Model S.

4. TPMS Reset

Sub-steps:
- Go to the Tesla touchscreen and navigate to 'Service' > 'Tire Pressure Monitoring System'.
- Select the option to reset the TPMS.
- Confirm the reset and monitor for the warning to disappear.
