SYSTEM DESCRIPTION

1. THEFT DETERRENT SYSTEM DESCRIPTION
The theft deterrent system is designed to deter vehicle break-ins and theft. If an attempted break-in or theft is detected, a vehicle horn and security horn will sound; room lamps will illuminate; and hazard warning lamps, taillamps and headlamps will begin flashing. The system uses these cues to detect an attempted break-in or theft: 1) vehicle is forcibly entered, 2) engine hood is forcibly opened, 3) doors are unlocked without the use of a key, or 4) the cable from the negative (-) battery terminal is disconnected and then reconnected.

If the system enters the alarm sounding state, any unlocked doors will automatically lock. The system has 2 modes: active arming mode (see On-Vehicle Inspection, step 2) and passive arming mode (see On-Vehicle Inspection, step 3). Passive arming mode can be toggled ON and OFF (see On-Vehicle Inspection, step 4).

Each mode has 4 states: disarmed state, arming preparation state, armed state and alarm sounding state.
