Features & Controls Theft-Deterrent System(CONI:) If the SECURITY light comes on for one minute and then shuts off while the ignition is on, the security system has detected a problem with itself. See your dealer for service. If a door or the trunk is opened without the key or the Keyless Entry transmitter, the alarm will go off. It will also go off if the trunk lock is damaged or if the ignition is turned on. Your vehicle's lights will flash and the horn will sound for three minutes, then will gooff to save battery power. And your vehicle will not start. 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 transmitter...I To Avoid Setting Off the Alarm by Accident: If you don't want to arm the theftdeterrent system, the vehicle should be locked with a key after the doors are closed. Always unlock a door with a key, or use the Keyless Entry System transmitter. Unlocking a door any other way will set off the alarm. To Stop the Alarm: If you set off the alarm by accident, unlock any door with your key. You can also turn off the alarm pressing the by UNLOCK button on the Keyless Entry System transmitter.
