CIRCUIT OPERATION
NOTE: If armed volumetrically, the vehicle
CANNOT be disarmed using the key.

available as original equipment. The main function
of the system is to offer easy–to–use remote
locking and unlocking of the vehicle without having
to actively select the alarm function.

ANTI–THEFT SYSTEM FUNCTION
Perimetric Protection
Using the key in the correct sequence will turn on
and off perimetric protection only. When fully
perimetrically armed, all doors, tailgate, and bonnet
are protected against unauthorized access. If the
door key is used in the normal manner the driver
will be unaware of the door key sequence. The
time taken to lock or unlock with the key must be
less than 5 seconds. To prevent unauthorized
tampering, the alarm will sound if the key is held in
the unlocked position for longer than 5 seconds
when armed. Cranking is disabled when perimetric
protection is armed.
NOTE: When key is turned left or right, the
keyswitch input will be activated, in
conjunction with the sill button switch when
links are operated.
Volumetric Protection
Using the handset transmitter will turn On and Off
volumetric protection. In volumetric mode the
vehicle interior is protected using the Alarm Sensor
(X213). Using the handset also arms and disarms
the vehicle perimetrically. Cranking is disabled
