Interior monitor and towing protection
55
The anti-theft alarm system increases the level of protection against theft and
break-in
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 55.
› Movement in the vehicle
» page 55.
› Sudden and significant voltage failure of the electrical system.
› Uncoupling the trailer
» page 134, Trailer, connect and disconnect .
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.
54Operation

CAUTIONBefore leaving the vehicle, check that the doors and windows are closed in or-
der to ensure that the alarm system is fully operational.
Note
The working life of the alarm siren is 5 years.
Activating/deactivating
Read and observe
on page 55 first.
Activating
The alarm system is activated automatically approximately 30 seconds after
the vehicle is locked.
If the vehicle is unlocked and a door or the boot lid not opened within the next
45 seconds, the vehicle will lock again automatically and the SafeLock system
or anti-theft alarm system will be switched back on. This function is intended
to prevent the car being unlocked unintentionally.
Deactivating
The alarm system is deactivated automatically after the vehicle is unlocked. If
the vehicle is not opened within 45 seconds, the 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.
Interior monitor and towing protection

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 SafeLock system is deactivated. The interior monitor is however not acti-
vated.

If the boot lid is unlocked with the key symbol 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 the activation of the delayed locking, the door can be opened again after
closing within a limited period.
Delayed locking can be deactivated by a specialist garage at any time.

Operational faults
58
The electrical power windows can only be operated when the ignition is
switched on.
56Operation

WARNINGPower windows in the driver's door and the rear doors are equipped with a
force limiter (only applies to the Variant 2 ) » page 58 . If there is an obsta-
cle, the closing process is stopped and the window goes down by several
centimetres. The windows should nevertheless 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 143 , Windows and external 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 on the window may cause greater resistance as the win-
dow is closed. The window will stop and open again by several centimetres. It
is necessary to deactivate the force limiter to close the window » page 58.
■
Always make sure that the windows are closed when you leave the locked
vehicle.
■
Always close the windows before disconnecting the battery » page 58,
Force limitation .
■
The window lift mechanism is equipped with protection against overheater.
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-
heater protection has cooled down.
For the sake of the environment
At high speeds you should keep the windows closed to prevent unnecessarily high fuel consumption.
Note
When driving always use the existing heater, air conditioning and ventilation
system for ventilating the interior of the vehicle. With the windows open, dust
and other dirt can get into the vehicle. In addition, wind noises can occur at
certain speeds.Open / close windowsFig. 38
