Solution

1. Preparation

Tools Required: Digital tire pressure gauge, air compressor.
Ensure the vehicle is parked on a flat surface and the tires are cold for accurate pressure readings.

2. Check and Adjust Tire Pressure

Sub-steps:
1. Use the digital tire pressure gauge to measure the pressure in all four tires.
2. Compare the readings to the recommended tire pressure specified on the driver’s side door jamb.
3. If any tire is below the recommended pressure, use an air compressor to inflate it to the correct level.
4. Recheck the tire pressure after inflating to ensure it meets the recommended specifications.

3. Inspect Tires

Sub-steps:
1. Visually inspect each tire for obvious punctures, cuts, or irregularities.
2. Look for any bulges or uneven wear patterns that may indicate internal damage.
3. If damage is found, consider replacing the affected tire or having it repaired by a professional.

4. Reset the TPMS (if necessary)

Sub-steps:
1. If the tire pressure has been adjusted, navigate to the vehicle settings on the Tesla display.
2. Locate the TPMS reset option and follow the prompts to reset the system.
3. Monitor the display for confirmation that the warning light has cleared.
