This light will come on when you turn the ignition to ON. The light will stay on until the engine starts.

If the light flashes, the Passlock® system has entered a tamper mode. If the vehicle fails to start, see Passlock® .

If the light comes on continuously while driving and stays on, there may be a problem with the Passlock system. Your vehicle will not be protected by Passlock®, and you should see your dealer.
