Using OBD-II Scanner:
1. Connect the OBD-II scanner to the vehicle's OBD-II port (usually located under the dashboard).
2. Turn on the ignition without starting the engine.
3. Navigate to the airbag system section on the scanner.
4. Select the option to clear or reset the airbag light.
Manual Procedure (if applicable):
