THEFT DETERRENT SYSTEM
G11005
To deter theft of the vehicle, this system is designed to
sound an alarm if any of the doors, trunk or hood is
forcibly unlocked or opened, or the battery terminal is
disconnected and then reconnected while the vehicle is
locked.
The alarm blows the horn intermittently, flashes the headlights,
tail lights, turn signal lights and other exterior lights. When the
interior light switch is in the “DOOR” position, the interior lights
also turn on.
After the alarm is activated, when you unlock any door or the
trunk using a entry function, wireless remote control or
mechanical key, the tail lights turn on for about 2 seconds to
inform you that the system was activated.
