1. Locate the airbag control module. In most Beetles, it's located under the front seat.
2. Disconnect the battery for at least 15 minutes. This will clear the power from the airbag module and reset it.
3. Reconnect the battery.
4. Turn the ignition to the "ON" position but do not start the engine.
5. Wait for the airbag light to turn on and then turn off. This may take a few minutes.
6. Start the engine and check to see if the airbag light is still off.
If the airbag light is still on after following these steps, you may need to have your vehicle diagnosed by a qualified mechanic.
