wards it begins to flash evenly at longer intervals.
WARNINGIf the car is locked and the safe securing system activated, no people must
remain in the car as it will then not be possible to either unlock a door or
open a window from the inside. The locked doors make it more difficult for
rescuers to get into the vehicle in an emergency – risk to life!Individual settings

Anti-theft alarm system
Introduction
This chapter contains information on the following subjects:
Activating/deactivating
56
Interior monitor and towing protection
56
The anti-theft alarm system increases the level of protection against people
trying to break into the vehicle.
The alarm system triggers audible and visual signals if an attempt is made to
break into the vehicle (hereafter referred to only as alarm).
Triggering the alarm
The alarm is triggered when the following unauthorized actions are carried out
on the locked vehicle.
› Opening the bonnet.
› Opening the boot lid.
› Opening the doors.
› Manipulation of the ignition lock.
› Towing the vehicle
» page 56.
› Movement in the vehicle
» page 56.
› Sudden and significant voltage drop of the electrical system.
› Uncoupling the trailer
» page 163, Coupling / uncoupling trainer .
If the driver's door of a vehicle with a remote control is unlocked and opened by the lock cylinder, then the alarm is triggered.
Switching off the alarm
The alarm is turned off by pressing the button on the radio remote control
key or switching on the ignition.
CAUTION
Before leaving the vehicle, it must be checked that all of the windows, doors
and the sliding/tilting roof are locked in order to ensure the full functionality of
the anti-theft alarm system.
Note
The working life of the alarm siren is 5 years.Activating/deactivating
Read and observe
on page 56 first.
Activating
The anti-theft alarm system is activated automatically approximately 30 sec-
onds after the vehicle is locked.
If you unlock the vehicle and do not open a door or the boot lid within the next
30 seconds, the vehicle will lock again automatically and the safelock system
or anti-theft alarm system will be switched on. This function is intended to
prevent the car being unlocked unintentionally.
Deactivating
The anti-theft alarm system is deactivated automatically after the vehicle is
unlocked. If the vehicle is not opened within 30 seconds, the anti-theft alarm
system is automatically activated again.
The alarm system is also deactivated if you unlock the driver door using the
key within 45 seconds of locking the vehicle.
Note
You can switch the audible signalling of the activation of the warning system
on and off in the Maxi DOT display in the menu item ATA confirm » page 47 .
Interior monitor and towing protection

Activating
The interior monitor and the towing protection are activated automatically af-
ter the vehicle is locked.
Deactivate›

›
Open the driver door.
›
Press the symbol button
» Fig. 38 on the B column of the driver's side.
The illumination of the symbol
in the button changes from red to orange.

Lock the vehicle within 30 seconds.
Deactivate the interior monitor and the towing protection if there is a possibili-
ty of the alarm being triggered by movements (e.g. by children or animals)
within the vehicle interior or if the vehicle has to be transported (e.g. by train
or ship) or towed.
CAUTION
■ The opened glasses storage compartment reduces the effectiveness of the
interior monitor. To ensure the full functionality of the interior monitor, the
glasses storage compartment must always be closed before locking the vehi-
cle.■
The anti-theft alarm system is activated when the vehicle is locked even if
the safe securing system is deactivated. The interior monitor is however not
activated.
Luggage compartment lid
Introduction
This chapter contains information on the following subjects:
Opening/closing
57
Delayed locking of the boot lid
58WARNING■ Ensure that the lock is properly engaged after closing the boot lid. Other-
wise, the lid might open suddenly while the vehicle is moving, even if the
lid was locked – risk of accident!■
Never drive with the boot lid open or ajar, as otherwise exhaust gases
may get into the interior of the vehicle – risk of poisoning!
WARNING (Continued)■ Do not press on the rear window when closing the luggage compartment
lid, it could crack – risk of injury!■
Make sure that when closing the boot lid, no body parts are crushed -
there is danger of injury!
Note
The function of the button in the grip above the licence plate is deactivated
when starting off or at a speed of 5 km/hour or more for vehicles with central
locking. The function is restored after the vehicle stops and the door is
opened.

Delayed locking of the boot lidRead and observe
on page 57 first.
If the boot lid is unlocked with the symbol button
on the remote control
key, then the door is automatically locked after closing.
The period after which the boot lid is locked automatically can be extended by a specialist garage.
After activation of delayed locking, the boot lid can be opened again after clos-
ing within a limited period.
Delayed locking can be deactivated by a specialist garage at any time.
CAUTION
There is a risk of unwanted entry into the vehicle before the boot lid is locked
automatically. We therefore recommend locking the vehicle with the symbol
button
on the remote control key.

Window convenience operation

Operational faults
60WARNINGThe system is fitted with a force limiter » page 60. If there is an obstacle,
the closing process is stopped and the window goes down by several centi-
metres. However, the windows should be closed carefully – risk of injury.CAUTION■ Keep the windows clean to ensure the correct functionality of the electric
windows.■
In the event that the windows are frozen, first of all eliminate the
ice » page 172 , Windows and mirrors and only then operate the electrical
power windows. Otherwise, the window sealing and the electrical power win-
dow mechanism could be damaged.
■
In the winter, ice accumulating on the surface of the window may cause
there to be more resistance when closing the window. The window will stop
and move back several centimetres.
■
It is necessary to deactivate the force limiter to close the win-
dow » page 60 .
■
Make sure that the windows are closed whenever you leave the locked vehi-
cle.
■
Always close the sliding/tilting roof before disconnecting the battery.
For the sake of the environment
At high speeds you should keep the windows closed to prevent unnecessarily high fuel consumption.
Note
■ After switching the ignition off, it is still possible to open or close the win-
dows for approx. 10 minutes. After the driver's or front passenger's door has
been opened, the windows can only be operated by using button A
» Fig. 40
on page 59 .
■
When driving always use the existing heating, air conditioning and ventila-
tion system for ventilating the interior of the vehicle. If the windows are
opened, dust as well as other dirt can get into the vehicle and in addition the wind noise is more at certain speeds.
■
The window lift mechanism is equipped with protection against overheating.
Repeated opening and closing of the window can cause this mechanism to
overheat. If this happens, it will not be possible to operate the window for a
short time. You will be able to operate the window again as soon as the over-
heating protection has cooled down.

Force limitRead and observe
and on page 58 first.
The electrical power window system is fitted with a force limiter.
If there is an obstacle, the closing process is stopped and the window goes
down by several centimetres.
If the obstacle prevents the window from being closed during the next 10 sec-
onds, the closing process is interrupted once again and the window goes down
by several centimetres.
If you attempt to close the window again within 10 seconds of the window be-
ing moved down for the second time, even though the obstacle was not yet
been removed, the closing process is only stopped. During this time it is not
possible to automatically close the window. The force limiter is still switched
on.
The force limiter is only switched off if you attempt to close the window again
within the next 10 seconds - the window will now close with full force!
If you wait longer than 10 seconds, the force limiter is switched on again.
Window convenience operation
