Diagnostic Steps

Check tire pressures using a tire pressure gauge to ensure all tires are inflated to the manufacturer's recommended levels.
2
Inspect the TPMS sensors for damage or faults, especially if they were recently replaced or if tires were changed.
3

Solution

1. Preparation

Ensure all tires are inflated to the correct pressure (refer to the door jamb label for specifications).
Gather necessary tools: tire pressure gauge, OBD-II scanner (if needed), and vehicle owner's manual for reference.

2. Resetting TPMS through the Vehicle Settings

Sit in the driver’s seat and ensure the engine is off.
Turn the ignition to the "On" position without starting the engine.
Locate the "Menu" button on the steering wheel and press it to access the vehicle settings on the dashboard display.
Navigate to the "Tire Pressure" or "TPMS" settings using the arrow keys.
Select the option to "Reset" or "Initialize" the TPMS.
Confirm the reset when prompted by the system.

3. Manual Reset (if applicable)

With the vehicle in "On" position, locate the TPMS reset button (usually found beneath the steering wheel or on the dashboard).
Press and hold the TPMS reset button until the TPMS warning light blinks three times, then release the button.
Start the vehicle and allow it to run for approximately 20 minutes; this allows the system to recognize the sensors.

4. Final Check

Drive the vehicle for at least 10 minutes to allow the TPMS system to recalibrate and verify that the warning light has turned off.
