1993 Cadillac Eldorado Owner's Manual - Page 87

THEFT DETERRENT (OPTION) If your Cadillac has this option, it has a Theft Deterrent Alarm System. With this system, the "SECURITY" light will flash as you open the door (if your ignition is off). This light reminds you to arm 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 Keyless Entry System. The "SECURITY" light should come onand stay on. 3. Close all doors. The "SECURITY" light should go off. If a door or the trunk opened without the key or Keyless Entry System, is the alarm will go off. It will also go off if the trunk lock is damaged. Your vehicle's lights will flash and the hornwill sound for 3 minutes, then will go off to save battery power. Remember, the theft deterrent system won't arm if you lock the doors with a key or manual door lock. It arms only if you use a power door lock switch or Keyless Entry System. Here's how to avoid setting off the alarm by accident: If you don't want to arm the theft deterrent system, the vehicle should be locked with the door key after the doors are closed. Always unlock a door with a key, or use the Keyless Entry System. Unlocking a door any other way will set off the alarm. If you set off the alarm by accident, unlock any door with your key. You can also turn off the alarm by using the Keyless Entry System, if you have it. The alarm won't stop if you try to unlock a door any other way. 73
