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 tr unk (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 s witch, keyfob or Intelligent Key after all doors and trunk
(sedan) are closed.
• All doors and trunk (sedan) are closed after front door s are locked by key or door lock and unlock switch.
The security indicator lamp illuminates for 30 seconds. t hen, 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).

NOTE:
• When any initialization is performed, all ID previ ously registered will be erased and all NATS mechanical
keys must be registered again.
• The engine cannot be started with an unregistered key. In this case, the system will show “DIFFERENCE OF
KEY” or “LOCK MODE” as a self-diagnos tic result on the CONSULT-III screen.
• In rare case, “CHAIN OF ECM-IMMU” might be stored as a self-diagnostic result during key registration pro-
