Solution

1. Preparation

Ensure all tires are inflated to the recommended pressure (check the sticker located on the driver’s door jamb).
Turn the ignition to the "ON" position without starting the engine.

2. Reset TPMS

Locate the Reset Button:
- Find the TPMS reset button, usually located beneath the steering wheel or on the dashboard.
Press and Hold the Reset Button:
- Press and hold the reset button until the tire pressure light blinks three times, then release the button.
Start the Engine:
- Start the engine and let it run for a few minutes; the TPMS should recalibrate automatically.
Check the Dashboard:
- Observe the dashboard for the tire pressure warning light. It should turn off if the reset was successful.
