Switching the windshield wiper
on/off
! Do not operate the windshield wipers
when the windshield is dry, as this could
damage the wiper blades. Moreover, dust
that has collected on the windshield can
scratch the glass if wiping takes place when
the windshield is dry.
If it is necessary to switch on the windshield
wipers in dry weather conditions, always use
washer fluid when operating the windshield
wipers.
! If the windshield wipers leave smears on
the windshield after the vehicle has been
washed in an automatic car wash, wax or
other residues may be the reason for this.
Clean the windshield using washer fluid
after washing the vehicle in an automatic
car wash.
! Intermittent wiping with rain sensor: due
to optical influences and the windshield becoming dirty in dry weather conditions,
the windshield wipers may be activated
inadvertently. This could then damage the
windshield wiper blades or scratch the wind-
shield.
For this reason, you should always switch
off the windshield wipers in dry weather. 1

X Turn the í wiper switch to the corre-
sponding position.
In the Ä or Å
positions, the appropriate
wiping frequency is set automatically accord-
ing to the intensity of the rain. In the Å
position, the rain sensor is more sensitive to
precipitation than in the Ä position, caus-
ing the windshield wipers to wipe more fre-
quently.
The windshield will no longer be wiped prop-
erly if the wiper blades are worn. This may pre-
vent you from observing the traffic conditions.
Information on replacing the wiper blades can
be found under "Replacing wiper blades"

ted for about 30 minutes at low fan setting
and 3-zone automatic climate control is dried
out. Optimum use of the rear compart-
ment air conditioning
Vehicles with air-conditioning system
Switch the rear-compartment air-conditioning
system on and off using the air-conditioning
system control panel. When you switch on the
rear-compartment air conditioning, your set-
tings for temperature, airflow and air distribu-
tion are automatically adopted on the control

control
To operate the rear-compartment air condi-
tioning, use the control panel of the dual-zone
automatic climate control system. When you
switch on the rear-compartment air condition-
ing, you can set the temperature and airflow
separately on the control panel. The airflow
setting is automatically adopted for the rear-
compartment air conditioning. When dual-zone
automatic climate control is in à automatic
mode, the air distribution of the rear-compart-
ment air conditioning is also automatically
adjusted.
When you set the temperature and airflow of
the rear-compartment air conditioning, the indicator lamp of the / button
(Y page

116) flashes. When the rear-compart-
ment air conditioning is switched on, the indi-
cator lamp on the / button lights up.

Important safety notes G
WARNING
Lane Keeping Assist cannot always clearly
detect lane markings.
In such cases, Lane Keeping Assist can:
R give an unnecessary warning
R not give a warning
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, espe-
cially if Lane Keeping Assist alerts you. G
WARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There
is a risk of an accident.
You should always steer, brake or accelerate
yourself, in particular if warned by Lane
Keeping Assist.
If you fail to adapt your driving style, Lane
Keeping Assist can neither reduce the risk of
accident nor override the laws of physics.
Lane Keeping Assist cannot take into account
road, weather or traffic conditions. Lane Keep-
ing Assist is only an aid. You are responsible
for the distance to the vehicle in front, for
vehicle speed, braking in good time and for
staying in your lane.
Lane Keeping Assist does not keep your vehi-
cle in its lane.
The system may be impaired or may not func-
tion if:
R there is poor visibility, e.g. due to insuffi-
cient illumination of the road, or due to
snow, rain, fog or spray
R there is glare, e.g. from oncoming traffic,
the sun or reflection from other vehicles
(e.g. if the road surface is wet)
R the windshield is dirty, fogged up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera
R there are no lane markings, or several
unclear lane markings for one lane, e.g.
around construction sites R
the lane markings are worn away, dark or
covered up, e.g. by dirt or snow
R the distance to the vehicle in front is too
short and thus the lane markings cannot be
detected
R the lane markings change quickly, e.g. lanes
branch off, cross one another or merge
R the road is narrow and winding
R there are highly variable shade conditions
on the road

Driving systems
Driving and parking

The rear view camera is a visual parking aid. It
shows you the area behind the vehicle in the
audio display.
The area behind the vehicle is displayed in a
mirrored fashion, as in the rear-view mirror or
the exterior mirrors. The guide lines displayed
assist you in backing up.
The message displays depend on the language
setting of the audio system. The following rear
view camera displays are examples.
Important safety notes !
Objects that are not at ground level appear
further away than they actually are, for
example:
R the bumper of the vehicle parked behind
R the drawbar of a trailer
R the ball coupling of a trailer tow hitch
R the tail-end of a truck
R slanted posts
Only use the camera guide lines for orienta-
tion. Do not get any closer to objects than
the lowest horizontal guide line. You may
otherwise damage your vehicle and/or the
object.
The rear view camera is only an aid. It cannot
replace your own awareness of the immediate
surroundings. You are responsible for safe
maneuvering and parking. Make sure that
there are no persons, animals or objects in the
maneuvering area while maneuvering and
parking in parking spaces.
The rear view camera may show obstacles in
perspectival distortion, incorrectly or not at all.
The rear view camera cannot display all
objects located very near and/or under the
rear bumper. It does not warn you of a colli-
sion, persons or objects.
Under the following circumstances, the rear
view camera will not function, or will function
in a limited manner:
R if the tailgate or rear-end door is open.
R if it is raining very heavily or snowing, or it is
foggy.
R at night or in very dark places.
R if the camera is exposed to very bright light.
White lines may appear in the camera image
R if the area is lit by fluorescent light, e.g.
from fluorescent lamps or LED lighting.
The camera image may flicker. R
if the camera lens fogs up, e.g. when driving
into a heated garage in winter, causing a
rapid change in temperature.
R the camera lens is dirty or obstructed.
Observe the notes on cleaning.
(Y page
267)
R if the rear of the vehicle is damaged.
In this case, have the camera position and
setting checked at a qualified specialist
workshop.
R the display has pixel errors.
Have the display repaired or replaced if usa-
bility is significantly reduced due to pixel
errors.
Do not use the rear view camera in these sit-
uations. You could otherwise injure others or
damage objects and the vehicle while parking
and maneuvering.
The field of vision and other functions of the
rear view camera may be restricted due to
additional accessories on the rear of the vehi-
cle (e.g. license plate holder, rear-mounted
bicycle rack).
Guide lines are always shown at road level. In
trailer mode, the guide lines are shown at the
level of the trailer coupling.
If you change wheel size, make sure they cor-
respond to the correct wheel size category
( Y page 278). If the category is changed with-
out recoding the control units in the vehicle,
the rear view camera cannot be precisely cali-
brated. The guide lines at road level or at the
level of the trailer tow hitch will not be dis-
played correctly.
In vehicles with a tailgate, the rear view cam-
era is protected from raindrops and dust by
means of a flap. When the rear view camera is
activated, this flap opens.
The flap closes again when:
R you have finished the maneuvering process
R you switch off the engine
For technical reasons, the flap may remain
open briefly after the rear view camera has
been deactivated. 164
