64The windscreen wipers and the wash system only operate if the ignition is switched on and the bonnet is closed
9).
If the intermittent wipe is switched on, the intervals are also controlled depending on speed. The rain sensor* automatically regulates
the break between the individual wiper
strokes depending on the intensity of the rain. The rear window will be wiped again if the front window wipers are on when reverse gear is selected. The windscreen washer nozzles are heated* when the ignition is switched on.Top up with wash liquid
⇒page 214.
Winter position If the windscreen wipers are in rest positi
on, they cannot be folded out from the wind-
screen. For this reason we recommend adjusting the windscreen wipers in winter so that they can be folded out from the windscreen easily. You can set this rest position as follows:•
Switch on the windscreen wipers.
•
Switch off the ignition. The windscreen wipers remain in the position in which they
were when switching off the ignition. You can also use the service position
⇒page 65 as a winter position.
WARNING
•
Properly maintained wind
screen wiper blades are essential for clear visi-
bility and safe driving
⇒page 65.
•
Do not use the windscreen washer sy
stem at low temperatures, without
heating the windscreen beforehand.
Otherwise the window cleaner could
freeze on the windscreen and re
strict the view to the front.
•
The rain sensor only operates as a support. The driver is not released from
the responsibility to set the function of the windscreen wipers manually depending on the visibility conditions.
Caution
In frosty weather, please firs
t of all check whether the windscreen wiper blades are not
frozen to the windscreen before switching them on. Switching on windscreen wipers when the blades are frozen to the windscreen may result in damage both to the blades and the motor of the windscreen wipers!
Note
•
If the slower or the faster wiper setting is switched on
⇒page 63, fig. 57
and
the vehicle speed decreases to below 4 km/h, the lower wiper step is switched on automatically. At a speed increase of more
than 8 km/h the previous wiper setting is
established again.•
If there is an obstacle on the windscre
en, the wiper will try to push away the
obstacle. If the obstacle continues to block
the wiper, the wiper stops after 5 cycles, in
order to avoid a damage to the wiper. Re
move the obstacle and and switch on the
wiper again.Automatic rear window wiper*If the windshield wiper lever is in the posi
tion or , the rear window wiper carries
out a wiping process every 30 seconds or
10 seconds at a speed above 5 km/h.
When the rain sensor* is active (the lever
is in the position ) the function is only
active if the front window wipers continue
to operate (no break between each wiping
process). Activation/deactivation The function of the automatic rear window wiper is activated/deactivated in the infor- mation display* in the menu: „
Setup „
Lights & Vision (Lights & Vision) „
Rear wiper
Note
The function of the automatic rear window
wiper is only valid for vehicles which are
equipped with the information display*. The function is activated in the factory.
9)On vehicles which do not have
a contact switch for the bonnet, the windshield wiper and wash
system operates also when
the bonnet is opened.

Alternative park position of the rear window wiperEach time after switching off the engine for
the second time, the wi
per blade of the rear
window wiper is tilted when the park position
is activated. Thus, the life of the wiper
blade is prolonged.Activating– Switch on the ignition - position
⇒page 109.
– Push the operating level in the position
⇒page 63, fig. 57
five times in succes-
sion within 5 seconds.
– Switch off the ignition. After switching on
the ignition again, the alternative park
position of the rear window wiper is activated.
– For deactivating the alternative park position of the rear window wiper, proceed in
the same way.
Headlight cleaning system*The headlights are being cleaned after the windscreen has been sprayed for the first time and fifth time, the low beam or main beam are switched on and the windscreen wiper lever was held in the position
⇒page 63, fig. 57
for about 1 second.
The headlight washer nozzles are moved forward out of the bumper by the water pres- sure for cleaning the headlights. You should remove stubborn dirt (such as in
sect residues) from the headlight lenses at
regular intervals, for example when refuelling
. Please refer to the following guidelines
⇒ page 196, “The headlight lenses”. You should remove any snow from the fixtur
es of the washer nozzles and clear ice in
winter with a de-icing spray in order to
ensure proper operation of the cleaning
system.
Replacing wiper blades for the windscreen wipersOne cannot fold out the wiper arms in the re

66Wiper blades in proper
condition are essential to obtain
good visibility
. Wiper blades
should not be allowed to become dirtied by
dust, insect remains and preserving wax.
Juddering or smearing of the
wiper blades could then be
due to wax residues left on
the windscreen by vehicle washing in automa
tic vehicle wash systems. It is therefore
important to
degrease
the lips of the wi
per blades after every pass through an
auto-
matic vehicle wash system
.
WARNING
•
If the windscreen wipers are handled carelessly, there is a risk of damage to
the windscreen.•
You should clean the wiper blades regu
larly with a windscreen cleaner in
order to avoid any smears. Clean a wiper blad
e with a sponge or cloth if it is very
dirty, for example from insect residues.•
Replace the wiper blades once or twice a year for safety reasons. The wiper
blades are available from specialist garages.Replacing the wiper blade on the rear window wiperTaking off the wiper blade– Fold windscreen wiper arm

WARNING
•
Convex (curved outward) or spherical (differently curved) exterior mirrors
increase the vision field. They do, however, make objects appear smaller in the mirror. These mirrors are only of limited
use, therefore, for estimating distances
to the following vehicles.•
Use whenever possible the interior rear
mirror, for estimating the distances
to the following vehicles.
Note
•
Do not touch the surfaces of the exterior
mirrors if the exterior

Technical Data
Seats and StowageFront seatsBasic informationThe front seats have a wide range of differ
ent settings and can thus be matched to the
physical characteristics of the driver and
front passenger. Correct adjustment of the
seats is particularly important for:•
safely and quickly reaching the controls;
•
a relaxed, fatigue-free body position;
•
achieving the maximum protection offered by the seat belts and the airbag
system.
WARNING
•
Never transport more occupants than the maximum seating in the vehicle.
•
Each occupant must correctly fasten the seat belt belonging to the seat.
Children must be fastened
⇒page 156, “Transporting children safely” with a
suitable restraint system.•
The front seats and the head restraints must always be adjusted to match
the body size of the seat occupant as well as the seat belts must always be correctly fastened in order to provide an optimal protection for you and your occupants.•
Always keep your feet in the footwell
when the vehicle is being driven -
never place your feet on the instrument panel, out of the window or on the surfaces of the seats. This is particular
ly important for the front seat passenger.
You will be exposed to increased risk of
injury if it becomes necessary to apply
the brake or in the event of an accident.
If an airbag is deployed, you may suffer
fatal injuries when adopting an incorrect seated position!•
It is important for the driver and front
passenger to maintain
a distance of at
least 25 cm from the steering wheel or
dash panel. Not maintaining this
minimum distance will mean that the airbag
system will not be able to properly
protect you - hazard! The front seats and the head restraints must always also be correctly adjusted to match the body size of the occupant.
•
Ensure that there are no objects in
the footwell as any objects may get
behind the pedals during a driving or braking manoeuvre. You would then no longer be able to operate the clutch, to brake or accelerate.•
Do not transport any objects on the front passenger seat except those
provided for this purpose (e.g. child safety seat) - risk of accident!Adjusting the front seatsAdjusting a seat in a forward/back direction–Pull the lever
⇒fig. 62
up and push the seat into the desired position.
– Release the lever and push the seat further until the lock is heard to engage.Adjusting height of seat– Lift the seat if required by pulling or pumping lever upwards.– Lower the seat if required by pushing or pumping lever downwards.Adjust the angle of the seat backrest– Relieve any pressure on the seat backrest (do not lean on it) and turn the hand-
