Solution

1. Preparation

Gather necessary tools: Tire pressure gauge, owner's manual (for reference).
Ensure all tires are inflated to the manufacturer's recommended pressure levels.

2. Manual Reset of TPMS

Locate the TPMS Reset Button:
- Typically found beneath the steering wheel, near the driver’s side door, or in the glove compartment. Consult the owner's manual for specific location.
Turn on the Ignition:
- Insert the key or press the start button without starting the engine (position II).
Press and Hold the TPMS Reset Button:
- Press and hold the TPMS reset button until the TPMS indicator light blinks three times, then release the button. The light should remain illuminated.
Start the Engine:
- Start the engine and let it run for a few minutes. The TPMS light should turn off as the system recalibrates.
Drive the Vehicle:
- Drive the vehicle for approximately 10-15 minutes at speeds above 20 mph. This allows the system to recalibrate and check that the TPMS light remains off.
