Theft-Deterrent Systems Vehicle theft is big business, especially in some cities. Although your vehicle has a number of theft-deterrent features, we know that nothing we put on it can make it impossible to steal. However, there are ways you can help. This message reminds you to activate the theft-deterrent system. Here's how to do it: 1. Open the door. 2. Lock the door with the power door lock switch or the remote keyless entry transmitter. The security light should come on and flash. If using the remote keyless entry transmitter, the door does not need to be open. Content Theft-Deterrent Your vehicle may be equipped with a content theft-deterrent alarm system. With this system, the security light will flash as you open the door (if your ignition is off), to let you know that you are activating the system. If the delayed locking feature is active, the alarm will not be activated until all doors are closed and the security light goes off. 3. Close all doors. The security light will stop flashing and stay solid. The light should go off after approximately 30 seconds. The alarm is not armed until the security light goes off. Ec 2-18
