– 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.

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 traffi c 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 o perate 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 coat ings 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.

70Exterior mirrors
The exterior mirrors are adjusted electrically.Adjusting exterior mirrors
– Turn the adjuster knob to position (left exterior mirror)
or position (right exterior mirror) ⇒fig. 72.
– Move the knob as required to adjust the exterior mirror for a good rearward view.
Heated mirrors
– Turn the knob to position .
Retracting both exterior mirrors*
– Turn the knob to position .The mirrors are heated depending on the outside temperature until
the ignition is switched off, even if the knob is no longer in position .
It may be advisable to retract* th e exterior mirrors to protect them
when parking or when driv ing through tight spaces. Memory for exterior mirrors*
On vehicles with memory function for the driver's seat, the setting
of the exterior mirrors is automati
cally stored together with the seat
position ⇒page 75 .
Tilting function for exterior mirror on passenger side*
(only if equipped with memory for exterior mirrors)
When reverse gear is engaged, th e mirror surface tilts slightly
downwards, provided the mirror control is switched to the exterior
mirror on the passenger's side (knob in position ⇒fig. 72). This
provides a better view of the kerb when parking.
The mirror returns to its original position when reverse gear is
disengaged and the vehicle is driven forwards at a speed above
about 15 km/h. The mirror will also return to its original position
when the adjuster knob is turned to the position for the driver's
exterior mirror or when the ignition is switched off.
If the position of the mirror surface is changed while the mirror is
tilted, this new position is automatically stored and assigned to the
remote control key when you disengage reverse gear.
Caution
•
Convex or wide-angle* exterior mirrors give a larger field of
vision. However, they also make objects appear further away than
they actually are. For this reas on, you should not rely on these
mirrors for judging the distance of vehicles behind.
•
If one of the mirror housings is knocked out of position (e.g.
when parking), the mirrors must firs t be fully retracted with the elec-
tric control. Do not readjust the mirror housing by hand, as this will
interfere with the mirror adjuster function.Note
If the electrical adjustment should ever fail to operate, the mirrors
can be adjusted by hand by lightly pressing the edge of the mirror
glass.
