• When doors or trunk is open, the vehicle security system is set in the disarmed phase on the assumption

that the owner is inside or near the vehicle.

• When the vehicle security system is in the disarmed phase, the security indicator lamp blinks every 2.4 sec-

onds.

Pre-armed Phase and Armed Phase

When the following operation 1 or 2 is performed, the vehicle security system turns into the “pre-armed”

phase. (The security indicator lamp illuminates.)
1. BCM receives LOCK signal from front door key cylinder switch or Intelligent Key, after trunk and all doors

are closed.

2. Trunk and all doors 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

When one of the following operations is performed, the armed phase is canceled.
1. Unlock the doors with the key or Intelligent Key.
2. Turn ignition switch “ON” or “ACC” position.

CANCELING THE ALARM OPERATION OF THE VEHICLE SECURITY SYSTEM

When unlocking the door with the key or Intelligent Key the alarm operation is canceled.

ACTIVATING THE ALARM OPERATION OF THE VEHICLE SECURITY SYSTEM

Check that the system is in the armed phase. (The security indicator lamp blinks every 2.4 seconds.)

When the following operation 1 or 2 is performed, the system sounds the horns and flashes the headlamps for

about 50 seconds.
1. Trunk or any door is opened during armed phase.
2. Disconnecting and connecting the battery connector before canceling armed phase.

PANIC ALARM OPERATION

Intelligent Key system will not operate vehicle security system (horn and headlamps) if the ignition switch is in

the ACC or ON position.

When the Intelligent Key system is triggered, ground is supplied intermittently to both headlamp relay and horn

relay.

When headlamp relay and horn relay are energized, then power is supplied to headlamps (LH and RH) and

horns (HIGH and LOW).

The headlamp flashes and the horn sounds intermittently.

The alarm automatically turns off after 50 seconds or when BCM receives any signal from Intelligent Key.
