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. When the alarm is armed, the trunk may be opened with the RKE transmitter. The power door lock switches are disabled and the doors remain locked. You must use your RKE transmitter or your key to unlock the doors when the system is armed. Arming with the Power Lock Switch The alarm system will arm when you use either power lock switch to lock the doors while any door or the trunk is open and the key is removed from the ignition. Content Theft-Deterrent Your vehicle may have the optional content theft-deterrent alarm system. To activate the theft-deterrent system: 1. Open the door. 2. Lock the door with the power door lock switch or the Remote Keyless Entry (RKE) transmitter. If you are using the RKE transmitter, the door does not need to be open. 3. Close all doors. Once armed, the alarm will go off if someone tries to enter the vehicle without using the RKE transmitter or a key or turns the ignition on with an incorrect key. The horn will sound and the turn signal lamps will flash for about two minutes. Arming with the RKE Transmitter The alarm system will arm when you use your RKE transmitter to lock the doors, if the key is not in the ignition. 2-18
