Security Light

This light will come on briefly when you turn the key toward START.
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.
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.
