Keyless Access is a key-free locking and igni-
tion system to unlock and lock the vehicle
without actively using its key. To do this, all
that is required is to have a valid vehicle key in
the detection area where you are attempting
to access the vehicle

Operation
Unlocking the vehicle is confirmed with a
d oubl
e
flash of the indicator lights; locking by
a single flash.
If the vehicle is locked and then all doors and
the rear lid are closed leaving the last key
used inside the vehicle and none outside, the
vehicle will not lock immediately. All the ve-
hicle

Opening and closing
The vehicle interior monitoring and the anti-
t o
w syst
em are automatically switched on
again next time the vehicle is locked.
The vehicle interior monitoring and anti-tow
sensor (tilt sensor) are automatically switch-
ed on when the anti-theft alarm is switched
on. In order to activate it, all the doors and
the rear lid must be closed.
If you wish to switch off the vehicle interior
monitoring and the anti-tow system, it must
be done each time that the vehicle is locked;
if not, they will be automatically switched on.
The vehicle interior monitoring and the anti-
tow system should be switched off if animals
are left inside the locked vehicle (otherwise,
their movements will trigger the alarm) or
when, for example, the vehicle is transported
or has to be towed with only one axle on the
ground.
False alarms
Interior monitoring will only operate correctly
if the vehicle is completely closed. Please ob-
serve related legal requirements.
The following cases may cause a false
alarm:
