66WARNINGThe system is fitted with a force limiter » page 65. If there is an obstacle,
the closing process is stopped and the window goes down by several centi-
metres. The windows should nevertheless be closed carefully – risk of in-
jury!
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 183 , Windows and external mirrors and only then operate the elec-
trical power windows. Otherwise, the window sealing and the electrical power
window 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 65 .
■
When leaving the locked vehicle make sure that the windows are closed at
all times.
■
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. 43
on page 64 .
■
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.

The lights work only with the ignition on, unless otherwise stated.
The arrangement of the controls right-hand drive models may differ from the layout shown in » Fig. 50 on page 71 . The symbols that mark the individual
positions of the controls are identical.
Keep the headlights lenses clean. The following guidelines must be ob-
served » page 184 , Headlight glasses .
WARNING■
The activation of the lights should only be undertaken in accordance with
national legal requirements.■
The driver is always responsible for the correct settings and use of the
lights.
WARNING (Continued)■ The automatic driving lamp control only operates as a support and
does not release the driver from his responsibility to check the light and, if
necessary, to switch on the light depending on the light conditions. The
light sensor cannot, for example, detect rain or snow. Under these condi-
tions we recommend switching on the low beam or fog lights!■
Never drive with only the side lights on! The side lights are not bright
enough to light up the road sufficiently in front of you or to be seen by oth-
er oncoming traffic. Therefore always switch on the low beam when it is
dark or if visibility is poor.
Note
■ The headlights may mist up temporarily. When the driving lights are switched
on, the light outlet surfaces are free from mist after a short period, although
the headlight lenses may still be misted up in the peripheral areas. This mist
has no influence on the life of the lighting system.■
The instruments are also illuminated when the side light, low or high beam
light is switched on. The brightness of the instrument lighting can be activated
or deactivated in the Infotainment » Operating instructions for Infotainment ,
chapter Vehicle settings (CAR button) .
