The alarm stops.
The alarm does not stop, even if you close the
open door that has triggered it, for example.
i If the alarm stays on for more than
30 seconds, the Mercedes‑Benz emergency
call system automatically sends a message to
the Customer Centre. This is sent via text
message or a data connection.
The emergency call system sends a message
or establishes a data connection provided
that:
R you have subscribed to the Mercedes‑Benz
emergency call system
R the Mercedes‑ Benz emergency call system
has been activated properly
R the necessary mobile phone network is
available Tow-away protection
Function An audible and visual alarm is triggered if your
vehicle's angle of inclination is altered while
tow-away protection is primed. This can occur if
the vehicle is jacked up on one side, for exam-
ple.
Activating/deactivating Tow-away protection is automatically switched
on and off with the ATA (anti-theft alarm system) when:
R the doors are closed
R the boot lid is closed
Tow-away protection is active around
60 seconds after the ATA has been switched on (Y page 78). Deactivating To prevent a false alarm, deactivate tow-away
protection if you lock your vehicle and it:
R is being transported
R is being loaded, e.g. onto a ferry or car trans-
porter
R is parked on a movable surface, e.g. in a split-
level garage
The tow-away alarm remains deactivated until
you switch the ATA on again after opening a
door.
You can deactivate tow-away protection via the
multimedia system (see the Digital Owner's
Manual). Interior motion sensor
Function When the interior motion sensor is switched on,
a visual and audible alarm is triggered if move-
ment is detected in the vehicle interior. This can occur if someone reaches into the vehicle inte-
rior, for example.
Switching on/off The interior motion sensor is automatically
switched on and off with the ATA (Anti-Theft
Alarm system) when:
R the doors are closed
R the boot lid is closed
The interior motion sensor is active around ten
seconds after the ATA has been switched on
(Y page 78).
You can prevent false alarms by doing the fol-
lowing before switching on the ATA:
R close the side windows
R close the soft top
R make sure that no objects, such as mascots,
are attached to the rear-view mirror
Deactivating If you want to lock your vehicle and people or
animals are inside it, you can deactivate the
interior motion sensor.
The interior motion sensor remains deactivated
until you switch the ATA on again after opening
a door. Protection against theft
