The alarm system indicates the fol-
lowing changes visually and audi-
bly:
• Audible alarm: Depending on
local regulations, the acoustic
alarm may be suppressed.
• Visual alarm: By flashing of the
hazard warning lights and, if
applicable, the headlights.
To safeguard the function of the
alarm system, do not modify the
system.
The alarm system is switched off
and on at the same time as the
vehicle is unlocked and locked via
the remote control or Smart Key
System.
The alarm system is triggered on
opening a door if the door has been
unlocked using the integrated key
in the door lock.
To stop the alarm, see page 104.
The boot lid can be opened even
with the alarm system switched on.
On closing the boot lid, it is locked
again and monitored, as long as the
doors are locked. The hazard warn-

The alarm system responds, for
example, when there is an attempt
to steal a wheel or when towing
away.
The passenger compartment is
monitored to the height of the seat
cushions. Therefore the alarm sys-
tem, including the interior move-
ment detector, is switched on even
when the window is open. Falling
objects such as leaves can acci-
dentally trigger the alarm.
The tilt alarm sensor and the inte-
rior movement detector may trigger
an alarm without any unauthorised
activity taking place.
Possible situations for an unwanted
alarm:
• In washing bays or car washes.
• In two-level garages.
• During transport via motorail, car
ferry or trailer.
• When there are pets in the vehi-
cle.
• When the vehicle is locked after
starting to refuel.
The tilt alarm sensor and interior
protection can be switched off for
such situations.
The indicator lamp illuminates for
approximately 2 seconds and then
flashes again.
The tilt alarm sensor and the inte-
rior movement detector are
switched off until the next time the
vehicle is locked.

• Pull the switch as far as
the resistance point.
The window closes as long as the
switch is held.
• Pull the switch past the
resistance point.
The window closes automatically if the
door is closed. Pulling the switch again
stops the movement.
The anti-trap mechanism prevents
objects or parts of the body from
becoming trapped between the
door frame and window while a win-
dow is being closed.
If resistance or a blockage is
detected while a window is being
closed, the closing operation is
interrupted.
If an external danger or ice does
not allow you to close the windows
normally, proceed as follows:
1 Pull the switch past the
resistance point and hold it
there.
The window is closed with a restricted
anti-trap mechanism. If the closing
force exceeds a certain value, the clos- ing operation is interrupted.
2 Pull the switch past the
resistance point again within
approximately 4 seconds and
hold it there.
The window is closed without the
anti-trap mechanism.

in the event of an accident. There is a
danger of injury or even death. Adjust the seat before starting the journey.
Adjust the backre st to the most
upright position possible, and do not change it during the journey.
