Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor or portable tire inflator.
Ensure the vehicle is parked on a level surface and the tires are cold for accurate pressure reading.

2. Check and Inflate Tires

Sub-step 1: Remove the valve cap from the tire to be checked.
Sub-step 2: Use the tire pressure gauge to measure the current tire pressure. Note the reading.
Sub-step 3: Compare the reading to the recommended tire pressure listed in the owner’s manual or on the driver’s door jamb.
Sub-step 4: If the pressure is below the recommended level, connect the air compressor and inflate the tire to the specified pressure.
Sub-step 5: Replace the valve cap securely after inflation.

3. Reset TPMS (if necessary)

Sub-step 1: If the tire pressure is corrected and the warning persists, reset the TPMS through the vehicle settings. Access the TPMS menu in the Tesla interface.
Sub-step 2: Follow on-screen instructions to reset the system, ensuring all tires are correctly inflated before proceeding.
