DESCRIPTION AND OPERATION
INTRODUCTION
The Vehicle Theft Security System (VTSS) is pas-
sive system and is designed to protect against whole
vehicle theft. The system monitors vehicle doors,
trunk key cylinder, and ignition action for unautho-
rized operation.
The VTSS also deactivates the Universal Transmit-
ter (garage door opener) and trunk lid release button
when the vehicle is armed. The trunk lid can only be
opened using the key or RKE transmitter when the
VTSS is armed. When the vehicle is disarmed, the
systems are restored to normal operation.
The VTSS alarm activates:
• Sounding of the horn
• Flashing of the interior lamps
• Flashing of the headlamps
• An engine kill feature
Passive arming occurs upon normal vehicle exit:
Open door, lock with power locks, close door. The
Vehicle Theft security LED lamp in the instrument
cluster will flash quickly for 15 seconds, indicating
that arming is in progress. If no monitored switches
are activated during this period, the system will arm.
After 15 seconds the LED lamp will continue to flash
but at a slower rate. This indicates that the system
is armed. If the trunk key cylinder switch is not
sensed by the system, the LED lamp will remain lit
during the arming process, although the system will
still arm.
The system is to be considered as an active armed
system when using:
• The Remote Keyless Entry
• The Central Lock Feature.
If the LED lamp does not illuminate at all upon
door closing it indicates that the system is not arm-
ing or the LED lamp is not operation. Refer to the
System Self-Tests
Passive disarming occurs upon normal vehicle
entry by unlocking either door with the ignition key/

remote transmitter. This disarming will also halt the
alarm once it has been activated.
A tamper alert exists to notify the driver that the
alarm had been activated. If the alarm has since
timed-out for at least 3 minutes but not more than
18 minutes the tamper alert will sound. If the trunk
lid has been activated the tamper alert will sound till
the VTSS is disarmed. The temper alert consists of 3
horn pulses when the vehicle is disarmed.
The alarm system will not arm if the doors are
locked manually by pushing the lock knobs. This will
manually override the system.
CENTRAL LOCK/UNLOCK SYSTEM
The central lock/unlock system uses the Vehicle
Theft Security System door switch to lock and unlock
all doors using the key. Turning the key to the lock
position in the driver's or passenger's door will lock
all doors. Turning the key in the driver's door to the
unlock position once will unlock driver's door only.
Turning the key a second time within five seconds of
the first time will unlock all doors. Turning the key
in the passenger's door to the unlock position will
unlock all doors.
Using the door key cylinder or the RKE transmit-
ter lock/unlock operation will arm/disarm the Vehicle
Theft Security System.
TRIGGERING THE VTSS
Using the power door switch, ignition key or the
keyless transmitter will arm the system. Any of the
following actions will trigger the system:
(1) Opening any door.
(2) Removing the trunk lock cylinder.
(3) Turning the ignition to the ON position.
