Volumetric/Anti-lift Protection
The Vehicle Security Alarm system monitors the doors and decklid for unauthorized entry and the
ignition switch for unauthorized operation.The system also includes an intrusion sensor and vehicle tilt
sensor.The intrusion sensor monitors the vehicle interior for motion.The vehicle tilt sensor monitors the
vehicle for any tilting actions (tow away, tire removal, ferry transport, etc). A siren with battery backup
which senses interruptions of power and communications is also included.
If a perimeter violation triggers the security system, the siren will sound for 30 seconds and the
exterior lights will flash followed by approximately five seconds of no activity. This will continue for
eight cycles if no action is taken to disarm the system.
The alarm takes approximately 20 seconds to arm once the doors are locked with the key fob and
once armed, the LED indicator on the dash will blink whenever the system is armed. If motion is
detected during the arming period, the motion detection system is disabled.
To ensure the correct operation of the protection, completely close the side windows.
If a perimeter violation triggers the security system, the siren will sound and the exterior lights will flash.
To disable the volumetric protection, turn the ignition key from STOP to MAR-ON twice in a row, then
activate the alarm within 15 seconds, pushing the lock button on the remote control. When the
function is deactivated, this is indicated by the vehicle security light in the instrument panel
flashing for several seconds.
To disable the anti-lift protection, the ignition key must be turned from STOP to MAR-ON three times in
a row, followed by activating the alarm within 15 seconds, pushing the lock button on the remote control.
When the function is deactivated, this is indicated by the vehicle security light in the instrument
panel flashing for several seconds.
Any disabling of the volumetric/anti-lift protection must be repeated each time the instrument panel
is switched off.
