Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the tires are cold for accurate pressure readings.
Safety warning: Wear safety goggles to protect your eyes from debris.

2. Check and Adjust Tire Pressure

Remove valve caps from all tires.
Using a digital tire pressure gauge, measure the pressure in each tire.
Inflate or deflate each tire to the manufacturer's recommended pressure (found on the driver’s side door jamb).
Replace valve caps securely.

3. Reset TPMS

Navigate to the 'Service' menu on the Tesla touchscreen.
Select 'Tire Pressure' settings.
Follow prompts to reset the TPMS.
Confirm that the reset is complete by checking for any remaining warnings.

4. Inspect TPMS Sensors

If the warning persists, remove the tires from the wheels.
Inspect each TPMS sensor for signs of damage or corrosion.
If damaged, replace the sensors with new ones compatible with the Tesla Model S.

5. Final Assembly

Reinstall the tires onto the wheels, ensuring they are properly seated.
Torque lug nuts to the manufacturer's specifications (usually around 100 ft-lbs).
Re-check tire pressures after reinstallation.
