Overview
Alarm system
*
>
If the indicator lamp flashes for
10 seconds when the system is
disarmed: an attempted entry has
been detected in the period since the
system was armed.
Following triggering of an alarm, the
indicator lamp will flash continuously.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion
sensor may be switched off at the same
time. You can do this to prevent a false
alarm from being triggered (in garages
with elevator ramps, for instance), or
when the vehicle is transported by
trailer or train:
Lock the vehicle twice (= setting the
alarm). Press button 2 on the remote
control twice in succession or lock the
vehicle twice with the key. Refer to
page
34 .
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.
Reset the alarm to reactivate the tilt
sensor alarm system and the interior
motion sensor.
Interior motion sensor
The transmitter and receiver of the inte-
rior motion sensor are located in a trim
panel in the vehicle's roof.
In order for the interior motion sensor to
function properly, the windows and
sliding/tilt sunroof must be completely
closed.
However, be sure to deactivate the
interior motion sensor (see "Avoiding
unintentional alarms") when you wish to
leave the windows or sliding/tilt sunroof
open.
