Solution

1. Preparation

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

2. Check and Adjust Tire Pressure

Sub-steps:
1. Use the tire pressure gauge to measure the pressure of each tire.
2. Compare the readings with the recommended tire pressure found on the driver’s side door jamb.
3. If any tire is under-inflated, locate an air compressor.
4. Inflate the tire(s) to the recommended PSI as needed.
5. Recheck the tire pressure after inflation to ensure it is correct.

3. Inspect and Repair if Necessary

Sub-steps:
1. If any tire shows visible damage, remove it from the vehicle using a jack and lug wrench.
2. Inspect for punctures or leaks and repair or replace the tire as necessary.
3. If a valve stem is leaking, consider replacing it before remounting the tire.

4. Reset TPMS

Sub-steps:
1. After correcting the tire pressures, navigate to the settings on the Tesla display.
2. Find the option to reset or recalibrate the TPMS.
3. Follow the on-screen instructions to complete the reset process.

5. Final Inspection

Sub-steps:
1. Take the vehicle for a short drive to ensure the warning light has turned off.
2. Monitor the tire pressure readings for stability over the next few days.
