Solution

1. Preparation

Gather tools: tire pressure gauge, air compressor (if needed), vehicle owner's manual.
Ensure all tires are at the recommended pressure (check the driver's door jamb for specifications).

2. Inflate Tires

Sub-step 1: Using a tire pressure gauge, check the pressure of each tire.
Sub-step 2: If any tire is below the recommended pressure, use an air compressor to inflate it to the specified PSI.
Sub-step 3: Repeat for all tires including the spare if it has a TPMS sensor.

3. Reset the TPMS Light

Sub-step 1: Turn the ignition to the "ON" position without starting the engine.
Sub-step 2: Press the gas pedal three times within 10 seconds.
Sub-step 3: Turn the ignition off and then turn it back to "ON."
Sub-step 4: Start the vehicle. The TPMS light should turn off if the pressure is correct.
