A5.3.2 Security system
Base system
Provides standard vehicle arming, ie door ajar, actuator lockstatus, trunk lid or hood ajar and passenger door unlock- ing, does not include inclination or
Intrusion sensing
Detection of intrusion into the passenger compartment by removal or breakage of any glazed area, entry via any pro- tected enclosure and unauthorized door opening detection.
Inclination (tilt) sensing
Detection of unauthorized jacking /towing.
Passive arming
Arming of the security system, excluding intrusion sensors, without audible confirmation.
Audible tones
Audible indication of driver error when attempting to arm the system, or on initiation of deadlocking.
Engine immobilization
Automatic immobilization of the engine crank facility whenever the ignition key is turned to position 0.
A5.3.3 Convenience
All close
Automatic closure of open windows and sliding roof by prolonged action of key, or remote fob transmitter after door
locking.
Headlamp convenience
Automatic illumination of headlamps for driver convenience on operation of key fob button after locking sequence
completed.
Remote trunk lid release
Automatic release of the trunk lid lock on operation of the smaller key fob button after door unlocking.
Trunk valet isolate
Independent locking of the trunk lid to eliminate unauthorized entry to the luggage compartment.
Driver seat memory select
Automatic recall of a memorized driving position on operation of the smaller key fob button.
Intrusion sensing override
Allows intrusion sensing to be disabled until the next disarm action.
A5.3.4 Alarms
There are eight possible alarm activation modes; driver's door, hood, ignition key in (ignition auxiliary position, ignition ON), inclination, inner door handle action (causing actuator status switches to operate), intrusion, passenger door and
trunk.
Any of the above conditions occurring after the vehicle is fully armed will cause full alarm state.
Any of the above conditions, except door opening, occurring
after the vehicle is fully armed and active disarming is
selected will cause full alarm state. Door opening after active disarming selection will give a 30 second audible tick
period before full alarm is entered.
Any of the above conditions occurring
after the vehicle has been passively armed will give a 30 second audible tick
period before full alarm is entered.
Activation of full alarm state causes sidelights, direction indicators, interior lights or headlamps to flash (dependant
upon market variations), the security sounder to operate and the vehicle horns to operate
(if programmed to do so).
An error tone is generated if active arming is selected with either hood or trunk open, or the transmitter is pressed with
ignition key in auxiliary position.
