car rises above this level. 
Windscreen wipers
Windscreen wipers 
The windscreen wiper lever controls the windscreen wipers
and the automatic wash and wipe.
Fig. 99 Windscreen wip-
er lever
The windscreen wiper lever ⇒ 
Fig. 99 has the following settings: Short wipe
–
Move the lever down to position 1
to give the windscreen a
short wipe.
Intermittent wipe  / Rain sensor* (activate)
– Move the lever up to position 2
.
– Move the switch A
up or down to set the wiper intervals.
– In vehicles equipped with a rain sensor*, you can move the
switch A
up and down to set the sensitivity of the rain sensor.
Slow wipe
– Move the lever up to position 3
.
Continuous wipe
– Move the lever up to position 4
.
Automatic wash and wipe
– Pull the lever towards the steering wheel, 5
, to activate the
windscreen washer.
– Release the lever. The washer will stop and the wipers will keep
running for approximately 4 seconds.
Deactivating the windscreen wiper
– Pull the lever to basic position 0
.
General notes
The washers and wipers will work only when the ignition is switched on. 

129
Lights and visibility
If you stop briefly, e.g. at traffic lights, the wiper speed will automatically be
reduced. The rain sensor* will automatically be set to the intermittent wipe
function.
The windscreen washer jets are heated when the ignition is switched on.
The wiper intervals in the intermittent wipe setting are also varied automati-
cally according to the road speed (in addition to the manual delay setting).
When the lights are switched on you should only pull the lever briefly to
wash the windscreen, otherwise the headlight washers* will also be ena-
bled. This will use an unnecessary amount of fluid from the reservoir.
Rain sensor
The rain sensor* will only function in the intermittent wipe position. The in-
termittent wipe function is enabled automatically when it starts to rain.
If the windscreen wiper lever was in the intermittent wipe position when the
ignition was off, the rain sensor will not activate until you reach a speed of
6 km/h.
Use switch A
to set the sensitivity of the rain sensor*.
If you have selected a high sensitivity level for the rain sensor the wind-
screen wipers will react sooner to any moisture on the windscreen.
The wiper intervals in the intermittent wipe setting are also varied automati-
cally according to the road speed (in addition to the sensitivity setting).
WARNING
● For correct visibility and safe driving, the wiper must be in perfect
condition ⇒ page 213. Failure to do so could result in an accident.
● The rain sensor* is only intended to assist the driver. The driver is
still obliged to manually operate the windscreen wipers as required de-
pending on visibility.
● Do not use water-repellent coatings on the windscreen. In bad visibili-
ty 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 make noise.
CAUTION
● In the event of frost, check that the wiper blade has not frozen before
activating the windscreen wipers. Should the windscreen wiper system be
enabled when the blade is frozen, this could damage it or even the wind-
screen wiper system 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 trigger-
ing of the wipers and possible damage to the wiper system.
Note
● Check that the washer fluid reservoir is full before starting a long jour-
ney. Fill the reservoir ⇒ page 234.
● Worn or dirty wiper blades can cause smearing on the glass which can
also impair the effectiveness of the rain sensor*. Check the condition of
windscreen wiper blades at regular intervals. 

When the anti-dazzle function is enabled, the interior mirror will darken au-
tomatically according to the amount of light it receives. The anti-dazzle
function is disabled if:
● the interior lighting is switched on
● reverse gear is engaged
Sensors for automatic headlights*
When the light switch is set to the AUTO position, the dipped beam head-
lights are switched on and off automatically according to the ambient light
level with the aid of the sensors located in the interior mirror ⇒ page 116.
WARNING
Electrolyte fluid can leak from a broken mirror. This fluid can cause irrita-
tion to the skin, eyes and respiratory organs. Wash thoroughly with clean
water should you come into contact with this fluid. Seek medical assis-
tance if needed!
CAUTION
Electrolyte fluid leaking from a broken mirror can cause damage to plastic
surfaces. Use a sponge or similar to remove the fluid as soon as possible.
Note
● The interior mirror automatic anti-dazzle function* will only work proper-
ly if the sun blind* for the rear window is retracted and if there are no other
objects preventing light from reaching the 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 automatic headlight or anti-
dazzle function from working correctly or even from working at all. 

Retracting both exterior mirrors
–Turn the knob to position A
.
It is advisable to fold the exterior mirrors, for example when parking or when
driving through narrow spaces.
Heated mirrors
The mirrors are heated (depending on the outside temperature) when the
heated rear window ⇒ page 126 is switched on.
The exterior mirror heating is not activated at temperatures above approxi-
mately 20 °C.
Memory for exterior mirrors*
In vehicles with memory function for the driver seat, the setting of the exte-
rior mirrors is automatically stored together with the seat position
⇒ page 137.
Tilting function for exterior mirror on the passenger side* (only if equipped
with memory for exterior mirrors)
When reverse gear is engaged, the mirror surface tilts slightly downwards,
provided the mirror control is switched to the exterior mirror on the passen-
ger side (knob in position R
⇒ Fig. 102). This provides a better view of the
kerb when parking.
The mirror returns to its original position as soon as reverse gear is disen-
gaged and the vehicle is driven forwards at a speed above 15 km/h, or
when the mirror control is turned to position L
or to the neutral position
0.
CAUTION
● Rear view convex or aspheric* mirrors increase the field of vision, al-
though objects appear smaller and further away in the mirrors. Therefore,
you should not rely on these mirrors for judging the distance of vehicles be-
hind.
● If one of the mirror housings is knocked out of position (e.g. when park-
ing), the mirrors must first be fully retracted with the electric control. Do not
readjust the mirror housing by hand, as this will interfere with the mirror ad-
juster function.
Note
If the electrical adjustment ever fails to operate, the mirrors can be adjusted
by hand by lightly pressing the edge of the mirror glass. 
