lights or headlights are on.Automatic headlight control (AUTO)*
When the switch is set to AUTO, the headlights switch on automati-
cally according to the ambient light conditions, for instance in a
tunnel, at sunset, or in the rain or snow. The
 symbol lights up
when the dipped headlights are on. The headlights are switched on,
regardless of the light conditions, when you switch on the fog
lights.
The headlights are switched off automatically when you switch off
the ignition.
On vehicles with a rain sensor, the headlights switch on automati-
cally after several windscreen wiper cycles. The instrument lighting
does not switch on, however.
While using the automatic headlights you can activate the main
beam headlights as normal if this function has been activated in the
MMI. However, if you switch on the main beam headlights while
using the AUTO function and then do not switch back to the dipped
headlights setting, only the dipped headlights will come on the next
time you switch on the AUTO function. To be able to use the main
beam headlights again you must first pull the main beam lever back
to the "off" position and then push it forward to "on".
Malfunction of light sensor
If a malfunction should occur in the light sensor, the instrument
cluster will show the message:
 Automatic headlights / automatic wipers defective
For safety reasons, the dipped beam headlights will then be
switched on permanently when the light switch is set to the AUTO
position. However, you can still switch the lights on and off in the
normal way with the light switch. You should have the light sensor
checked by a qualified workshop as soon as possible.

– 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 interior rises above this level.
Windscreen wipersWindscreen wipers

Automatic wash and wipe
– Pull the lever to position .
– Release the lever again. The washer will stop and the
wipers will keep running for approximately 4 seconds.
The number of wipe cycles varies according to the length
of time the lever is pulled.
Switching off the wipers
– Move the lever to the "off" position .General notes
The washers and wipers will only work when the ignition is switched
on.
If you stop briefly, e.g. at traffic lights, the wiper speed will automat-
ically be reduced by one level.
The windscreen washer jets are heated when the ignition is
switched on if the outside temperature is low.
Dribble wipe
About 5 seconds after the wash and wipe cycle has finished, the
windscreen wiper system automatically gives the screen one extra
wipe to remove any dribbles of water.
If you want to deactivate the dribble wipe function while driving,
pull the lever to position again within 10 seconds.
The dribble wipe function will be re-activated the next time the igni-
tion is switched off and on.
Rain sensor*
The rain sensor will only function in the intermittent wipe position.
The intermittent wipe function is activated automatically when it
starts to rain.
Before you reach a road speed of 6 km/h you will have to activate the
rain sensor manually by switching it off and back on again.To reduce the sensitivity level of the rain sensor move control
⇒page 65, fig. 67 to the left. To increase the sensitivity level of the
rain sensor move the control to the right.
If you have selected a high sensitivity level for the rain sensor the
windscreen wipers will react sooner to any moisture on the wind-
screen. The wiper intervals in the intermittent wipe setting are also
varied automatically according to the road speed (in addition to the
sensitivity setting).
WARNING
•
Poor visibility can cause accidents. Always ensure that the
wiper blades are in good condition ⇒page 68, “Changing wiper
blades”.
•
The rain sensor is only intended to assist the driver. The driver
is still obliged to manually operate the windscreen wipers as
required depending on visibility.
•
Do not use water-repellent coatings on the windscreen. In bad
visibility conditions such as light rain, low sun or when driving at
night these coatings can cause increased dazzle, which is a
serious safety hazard. Such coatings can also cause the wiper
blades to judder.Caution
•
In icy conditions, always check that the wiper blades are not
frozen to the glass before using the wiper for the first time. If you
switch on the wipers when the wiper blades are frozen to the glass,
this could damage both the wiper blades and the wiper motor.
•
Make sure you switch off the windscreen wiper system (lever in
position "0") before you use an automatic car wash. This will avoid
inadvertent triggering of the wipers and possible damage to the
wiper system.

Note
•
Check that the washer fluid reservoir is full before starting a long
journey. Filling the reservoir ⇒page 267.
•
Worn or dirty wiper blades can cause smearing on the glass
which can also impair the effectiveness of the rain sensor. Please
check the wiper blades regularly.
Applies to vehicles: with headlight washersHeadlight washer systemThe headlight washer system only operates when the lights
are switched on.
– Move the automatic wash and wipe lever to position
⇒page 65, fig. 67.The headlight washer system is always activated the first time you
operate the automatic wash and wipe. Subsequently, it is only acti-
vated about every five wash and wipe cycles. The headlights are
always washed if you hold the lever for longer than about
2seconds.
The headlight washer jets come out of the bumper automatically
(under water pressure).
Clean off stubborn dirt (insects, etc.) from the lenses at regular
intervals, for instance when stopping for fuel.
To ensure that the system works properly in winter, keep the nozzle
holders free of snow and remove any ice with a de-icer spray.
Service position
Use the service position to change the wiper blades.You can set the wipers to the service position on the sound
system or MMI*.
– If the wiper blades are not frozen to the windscreen,
move the windscreen wiper lever to the "off" position
⇒page 65, fig. 67.
– Select: Function selector button > Windscreen
wipers > Service position ⇒fig. 68.•
