38 Luggage compartment
Alarm system*
When opening the convertible top,
refer to page 41, make sure that
the luggage compartment is set up for
this, otherwise you may damage some-
thing.<
You can have a signal set as
acknowledgment for both arming
and disarming the alarm.<
The concept
The vehicle alarm system responds:
>When a door, the hood or the lug-
gage compartment lid are opened
>To movement inside the vehicle –
interior motion sensor
>Altering the vehicle tilt, e.g. as would
occur while attempting to steal the
wheels or tow the vehicle – tilt alarm
sensor system
You can also open the luggage com-
partment lid when the system is armed
by pressing the button of the remote
control, refer to page 32. When it is
closed, the lid is once again secured.
>To interruption of battery voltage.
The system responds to unauthorized
vehicle entry and attempted theft by
simultaneously activating the following:
>Sounding an acoustic alarm for
30 seconds
>Activating the hazard warning flash-
ers for approx. five minutes
>Flashing the high beams on and off in
rhythm with the hazard warning flash-
ers.
To arm and disarm the alarm
system
When the vehicle is locked or unlocked
by using a key or with the remote con-
trol, the alarm system is also simulta-
neously armed or disarmed.

armed: an attempted entry has been
detected in the period since the sys-
tem was armed.
The tilt and interior motion sen-
sors are inadvertently switched off
when convenience closing of the win-
dows is interrupted within the first
10 seconds and then started again. If
this happens, they must be disarmed
and reactivated.<
Following triggering of an alarm, the
indicator lamp will flash continuously.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion
sensor may be deactivated 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 train:
Indicator lamp displays
>The indicator lamp below the interior
rearview mirror flashes continuously:
the system is armed
Lock the vehicle twice to arm the sys-
tem. Press button on the remote control
twice in succession or lock the vehicle
twice with the key.
>The indicator lamp flashes when it is
armed: the door(s), the hood or lug-
gage compartment lid are not com-
pletely closed. Even if you do not
close the alerted area, the remaining
areas are deadlocked, and the indi-
cator lamp flashes continuously after
ten seconds. However, the interior
motion sensor is not activated
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.
>If the indicator lamp goes out when
the system is disarmed: no manipula-
tion or attempted intrusions have
been detected in the period since the
system was armed
Interior motion sensor*
Deactivate the interior motion sensor –
see Avoiding unintentional alarms – if
persons or animals are left in the vehi-
cle.
