Locks and Security If there is any potential perimeter anti-theft problem with your vehicle, ensure ALL remote entry transmitters are brought to the dealership, to aid in troubleshooting. Arming the system When armed, this system will respond if unauthorized entry is attempted. When unauthorized entry occurs, the system will flash the turn signal lamps and will sound the horn. The system is ready to arm whenever the key is removed from the ignition. Either of the following actions will prearm the alarm system: • Press the control on the remote entry transmitter. When you press the lock control twice within three seconds on your remote entry transmitter, the horn will chirp once to let you know that all doors, the hood and the trunk are closed. If any of these are not closed, the horn will chirp twice to warn you that a door, the hood or the trunk is still open. • Press the driver or passenger interior door lock control while the door is open, then close the door. • Press the 7 • 8 and 9 • 0 controls on the keyless entry pad at the same time to lock the doors (driver's door must be closed). There is a 20 second countdown when any of the above actions occur before the vehicle becomes armed. Each door, the hood or the trunk is armed individually, and if any are open, they must be closed for the system to enter the 20 second countdown. The turn signal lamps will flash once when all doors, the hood or the trunk are closed indicating the vehicle is locked and entering the 20 second countdown. 85 2005 Montego (mgo) Owners Guide (post-2002-fmt) USA_English (fus)
