WARNING
● Worn and dirty wiper blades reduce visibility and safety levels while
driving.
● In cold conditions, you should not use the wash/wipe system unless
you have warmed the windscreen with the heating and ventilation sys-
tem. The windscreen washer fluid could otherwise freeze on the wind-
screen and obscure your view of the road.
● Always note the corresponding warnings on ⇒ page 245.
CAUTION
In icy conditions, always check that the wiper blades are not frozen to the
glass before using the wipers for the first time. If you switch on the wind-
screen wipers when the wiper blades are frozen to the windscreen, you
could damage both the wiper blades and the wiper motor.
Note
● The windscreen wipers will only work when the ignition is switched on.
● In certain versions of vehicles with alarms, the windscreen wiper will on-
ly work when the ignition is on and the bonnet closed.
● When in use, the wipers do not go as far as the rest position. When the
lever is moved to position 0, they are totally hidden.
● The next speed down will automatically be selected if wiper speed 2
⇒ Fig. 83 or 3 is selected when the vehicle stops. The set speed will be
resumed when the vehicle starts again
● The windscreen will be wiped again after approximately five seconds
once the “automatic wipe/wash system” has been operated, provided the
vehicle is in transit (drip function). If you activate the wipers less than three
seconds after the drip function, a new wash sequence will begin without the
last wipe. For the “drip” function to work again, you have to turn the ignition
off and then on again. ●
When the “interval wipe function” is on, the intervals are directly propor-
tional to the speed. This way, the higher the vehicle speed the shorter the
intervals.
● The wiper will try to wipe away any obstacles that are on the windscreen.
The wiper will stop moving if the obstacle blocks its path. Remove the ob-
stacle and switch the wiper back on again.
● Before removing any objects that may be trapped in the side areas of
the windscreen, always move the wiper arms to the service position (hori-
zontal).
● The heat output of the heated jets is controlled automatically when the
ignition is switched on, depending upon the outside temperature.

Rain sensor*
The rain sensor controls the frequency of the windscreen
wiper intervals, depending on the amount of rain.
Fig. 84 Rain sensor*
Fig. 85 Windscreen wip-
er lever Switching on the rain sensor
–
Move the windscreen wiper lever into position 1
⇒ Fig. 85.
– Move the control A
to the left or right to set the sensitivity of
the rain sensor. Control to the right: highly sensitive. Control to
the left: less sensitive.
The rain sensor is part of the interval wipe function. You will have to switch
the rain sensor back on if you switch off the ignition. This is done by switch-
ing the wiper interval wipe function off and back on.
Note
● Do not put stickers on the windscreen in front of the rain sensor. This
may cause sensor disruption or faults.

Rear window wiper
The window wiper lever operates the windscreen wiper and
the wash and wipe system for the rear window.
Fig. 86 Windscreen wip-
er and windscreen wash
lever: rear window wiper
Switching on the interval wipe
– Press the lever forwards to position 6
⇒ Fig. 86. The wiper will
wipe the window approximately every 6 seconds.
Switching off the interval wipe function
– Pull the lever back from position 6
towards the steering wheel.
The wiper will continue to function for a short period if you
switch off whilst the wipers are in motion.
Switching on the windscreen wiper and washer system
– Press the lever fully forwards to position 7
⇒ Fig. 86. The wash
function will start immediately and the wiper will start with a
slight delay. The windscreen wash system will function as long
as you hold the lever in this position. –
Release the lever. The wiper then wipes for approximately 4 sec-
onds, and then in intervals again.
– Release the lever. The washer system stops and the wipers
function.
WARNING
● A worn or dirty wiper blade will obstruct visibility and reduce safety.
● Always note the corresponding warnings on ⇒ page 245.
CAUTION
In icy conditions, always check that the wiper blade is not frozen to the
glass before using the wiper for the first time. If you switch on the wiper
when the wiper blade is frozen to the glass, this could damage both the
wiper blade and the wiper motor.
Note
● The windscreen wiper will only function when the ignition is switched on
and the rear lid is closed.
● In reverse gear, with the windscreen wipers switched on, the rear wind-
screen wiper will make one wipe.
Headlight washer*
The headlight washers clean the headlight lenses. The headlight washers are activated automatically when the windscreen
washer is used and the window wiper lever is pulled towards the steering
wheel for at least 1.5 seconds – provided the dipped beam headlights or
main beams are switched on. Clean off stubborn dirt (insects, etc.) from the
headlights at regular intervals, for instance when filling the fuel tank.

Note
● To ensure that the headlight washers work properly in winter, keep the
nozzle holders in the bumper free of snow and remove any ice with a de-icer
spray.
● To remove water, the windscreen wipers will be activated from time to
time, the headlight washers will be activated every three cycles.

darken automatically according to the amount of light it receives. The anti-
dazzle function is cancelled if reverse gear is engaged.

Note
● The automatic anti-dazzle function will only work properly if the sun
blind* for the rear window is retracted and there are no other objects pre-
venting light from reaching the interior rear vision mirror.
● If you have to stick any type of sticker on the windscreen, do not do so in
front of the sensors. Doing so could prevent the anti-dazzle function from
working well or even from working at all.
Exterior mirrors
The exterior mirrors can be adjusted using the rotary knob
in the centre console.

rior mirrors
Basic setting of exterior mirrors
1. Turn knob ⇒

Heating the exterior mirrors*
– Turn the knob forwards so that the heated rear view mirrors
warm up and the heated windscreen* in the wiper blade rest
area is activated ⇒ page 127.
– The exterior mirror heating is not activated in temperatures
above approximately +20 °C (+68 °F).
Folding in exterior mirrors*
– Turn the control ⇒ Fig. 88 to position to fold in the exterior
mirrors. You should always fold in the exterior mirrors if you are
driving through an automatic car wash. This will help prevent
damage.
Folding exterior mirrors with convenience closing*

ience closing (with the remote or the key).

mirror will be adjusted at the same time (synchronised).
WARNING
● Convex or aspheric mirrors increase the field of vision however the
objects appear smaller and further away in the mirrors. If you use these
mirrors to estimate the distance to vehicles behind you when changing
lane, you could make a mistake. Risk of accident.
● If possible, use the rear vision mirror to estimate distances to vehi-
cles behind you.
● Make sure that you do not get your finger trapped between the mirror
and the mirror base when folding back the mirrors. Risk of injury!
For the sake of the environment
The exterior mirror heating should be switched off when it is no longer nee-
ded. Otherwise, it is an unnecessary fuel waste.
Note
● If the electrical adjustment ever fails to operate, the mirrors can be ad-
justed by hand by lightly pressing the edge of the mirror glass.
● In vehicles with electric exterior mirrors, the following points should be
observed: if, due to an external force (e.g. a knock while manoeuvring), the
adjustment of the mirror housing is altered, the mirror will have to be com-
pletely folded electrically. Do not readjust the rear vision mirror housing by
hand, as this will interfere with the mirror adjuster function.
● The rear vision mirrors can be adjusted separately or simultaneously, as
described before.
● The fold-in function on the exterior mirrors is not active at speeds over
40 km/h (25 mph).
