• Perimeter alarm with interior sensors.
• Perimeter alarm with interior sensors

Interior sensors
The interior sensors are activated when
you arm the alarm. See Arming the alarm
(page 36).
WARNINGS
The sensors in the interior lamp unit
must not be covered up. Do not
activate the alarm if any persons,
animals or other moving objects are inside
the vehicle.
The interior sensors may not detect
movement with in the cab correctly
if the rear seat base in the double
cab is left in the upright position.
Do not leave the glasses holder open.

by the fuel fired heater. If you are using the
fuel fired heater, direct the air flow towards

Alarm

The sensors act as a deterrent against
unauthorised intrusion by sensing any
movement within the vehicle.
Alarm Horn
The alarm horn will sound a siren when the
alarm is triggered. It is armed when you
lock the vehicle. This will not sound if
someone disconnects the vehicle battery
or the alarm horn itself.
Battery back-up sounder
The battery back-up sounder is an extra
alarm system which will sound a siren
when the alarm is triggered. It is armed
when you lock the vehicle. The sounder
has its own battery and will sound an
alarm siren even if someone disconnects
the vehicle battery or the battery back-up
sounder itself.
Triggering the alarm
Once armed, the alarm is triggered in any
of the following ways:
• If someone opens a door or the bonnet
without a valid key or remote control.
• If someone removes the multi function
display.
• If the ignition is turned to position I, II
or III without a valid key.
• If the interior sensors detect movement
within the vehicle.
• On vehicles with a battery back-up
sounder, if someone disconnects the
vehicle battery or the battery back-up
sounder itself.
If the alarm is triggered, the alarm horn will
sound for 30 seconds and the hazard
warning flasher will flash for five minutes.
Any further attempts to perform one of the
above will trigger the alarm again.
