VEHICLE SECURITY (THEFT WARNING) SYSTEM
System Description
INFOID:0000000001704084
DESCRIPTION
Operation Flow

Setting the vehicle security system
Initial condition• Ignition switch is in OFF position.
Disarmed phase• When the vehicle is being driven or when any door or trunk (sedan) is open, the vehicle security system is
set in the disarmed phase on the assumption that the owner is inside or near the vehicle.
Pre-armed phase and armed phase• The vehicle security system turns into the "pre-armed" phase (security lamp illuminates) when the BCM
receives LOCK signal from front door key cylinder switch, keyfob or Intelligent Key after all doors and trunk
(sedan) are closed.
• All doors and trunk (sedan) are closed after front doors are locked by key or door lock and unlock switch.
The security indicator lamp illuminates for 30 seconds. then, the system automatically shifts into the "armed"
phase.
Canceling the set vehicle security system
Armed phase is canceled when the driver unlocks the doors or the trunk (sedan) with the key, keyfob or Intelli-
gent Key.
Activating the alarm operation of the vehicle security system
Make sure the system is in the armed phase.
When one of the following operations is performed, the system sounds the horns and flashes the headlamps
for about 50 seconds.
1. Any door is opened before unlocking door with key, keyfob or Intelligent Key.
2. Door is unlocked without using key, keyfob or Intelligent Key.
3. Trunk (sedan) is opened without using the key, trunk lid opener switch, keyfob or Intelligent Key (sedan).
