For 1990-2009 cars

This light will come on briefly when you turn the key to START. The light will stay on until the engine starts.

If the ignition is turned on, and 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.

Also, see Content Theft-Deterrent for additional information regarding the security light.
