Alarm system
*
> If the indicator lamp flashes for
10 seconds when the system is dis-
armed: An attempted entry has been
detected in the period since the sys-
tem was armed.
Following triggering of an alarm, the
indicator lamp will flash continuously.
Avoiding unwanted alarm
The tilt alarm sensor and interior motion
sensor may be switched off at the same
time. You can prevent triggering false
alarms in high-rise garages or if the
vehicle is transported on a car-carrier
train, for instance, by doing the
following:
Lock the vehicle twice (= arm the sys-
tem). Press button 2 on the remote con-
trol twice in succession or lock the vehi-
cle twice with the key (refer to page 36).
The indicator lamp lights up briefly and
then flashes continuously. The tilt alarm
sensor and the interior motion sensor
are deactivated as long as the system is
armed.
Interior motion sensor
The transmitter and receiver of the inte-
rior motion sensor are located in a trim
panel in the vehicle's headliner.
In order for the interior motion sensor to
function properly, the windows and
sliding/tilt sunroof must be completely
closed.
But make sure to turn off the interior
motion sensor (see previous column),
if
> children or animals are left in the
vehicle
> the windows and/or sunroof are left
open.
The tilt sensor and interior motion
sensor are deactivated if the con-
venience closing mode for the windows
and the sliding/tilt sunroof is interrupted
within the first 10 seconds and then
reinitiated. If this happens, you must
disarm the system and then re-arm
