light is controlled automatically, depending on the speed of the
vehicle and the steering wheel angle.
The headlights are regulated automatically when you drive through
a corner, depending on how far you turn the steering wheel. To
avoid having a dark spot in front of the vehicle the two headlights

– To retract the sun blind automatically when reversing,
select: Function selector button > Windows >
Automatic rear blind > on.If you switch the Automatic rear blind function on in the sound
system or MMI*, the raised sun blind will be retracted automatically
when reverse gear is engaged ⇒page 55 . In this way, the rear blind
will not obstruct your vision when reversing. The rear blind returns
to its raised position when reverse gear is disengaged and the
vehicle is driven forwards at a speed above about 15 km/h. The
current setting is automatically stored and assigned to the remote
control key.
If the rear blind was rolled in automatically when reversing and then
the ignition was switched off and on again, the blind will not roll
back out again when you select a forward gear and the speed
exceeds 15 km/h. You will then have to press the button
 on the
centre console to extend the blind again.
The sun blind for the rear window switches off automatically when
it reaches the end position. It can be made to move in the other
direction before it reaches its end position by briefly pressing the
switch a second time. If the ignition is turned off while the blind is
still moving, it continues until it reaches the end position before
switching off.
Note
•
An overload cut-out may be activated if the sun blind is operated
repeatedly. There will then be a short delay before the blind can be
operated again.
•
As the material of the sun blind is less flexible at low tempera-
tures the electric actuator is switched off when the temperature in
the car is below -5°C. The blind can only be operated when the
temperature in the car's inte rior rises above this level.
