Adaptive head lights (AHL)*
Switch on Adaptive headlights (AHL)*
– Turn the light switch ⇒page 54, fig. 42 into position
.
The outer illumination switches on if:
•the light sensor recognizes the low light intensity,
•no reverse gear is engaged,
•the operation “tourist light” is not switched on.
The light sensor switches on the full ou ter illumination at low light intensity,
System AHL* makes it possible to change the length and width of illumination of
the headlight. The length and width of illumination changes automatically in rela-
tion to the vehicle speed and the use of the windscreen wiper.
System AHL* operates in the following modes.
Mode out of town
The mode “out of town” is a basic mode. The dispersion of the cone of light in front
of the vehicle is similar to the low beam. Th e mode is active if none of the following
modes are active.
Mode rain
In the mode “rain” the dispersion of the cone of light in front of the vehicle is wider
and the width of illumination is shorter, so that during bad weather (rain) the
dazzling of the oncoming drivers can be re duced. The mode is activated at speeds
of 15 - 70 km/h and if the windscreen wi pers continuously operate for a period of
time longer than 2 minutes. The mode is deactivated when dropping below or
exceeding the set speed limit or if the windscreen wipers have been switched off for
a period of time longer than 8 minutes.

Fast wipe
– Position the lever up into position .
Automatic wipe/wash for windscreen
– Pull the lever towards the steering wheel into sprung position , the wash system sprays immediately, the windscreen wiper starts wiping
a little later. The wash system and the windscreen wiper operate
simultaneously at a speed of more than 120 km/h.
– Release the lever. The windscreen wash system stops and the wiper continues for another 3 - 4 wiper stro kes (depending on the period of
spraying of the windscreen). At a speed of more than 2 km/h, the wiper
wipes once again* 5 seconds after the last wiper stroke in order to
wipe the last drops from the windsc reen. This function can be acti-
vated/deactivated by a specialist garage.
Rain sensor*
– Move the lever into position .
– You can set the sensitivity of the sensor individually with switch .
Switching windscreen wipers off
– Move the lever back into its home position .
After the windscreen wiper switches off each time or the ignition switches off for
the third time, the position of the windscreen wiper changes, this counteracts an
early fatigue of the wiper rubbers.
The windscreen wipers and the wash system only operate if the ignition is switched
on and the bonnet is closed.
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 windscreen washer nozzles are heated* when the ignition is switched on. Top up with wash liquid
⇒page 220.
Winter position
If the windscreen wipers are in rest posi tion, they cannot be folded out from the
windscreen. For this reason we recommend adjusting the windscreen wipers in
winter so that they can be folded out fr om 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 as a winter position.
WARNING
•Properly maintained windscreen wiper blades are essential for clear visi-
bility and safe driving ⇒page 67.
•Do not use the windscreen washer system 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 manu-
ally depending on the visibility conditions.
Caution
In frosty weather, please first 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 65, fig. 58
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 cont inues to block the wiper, the wiper stops after 5 cycles,
in order to avoid a damage to the wiper. Remove the obstacle and and switch on
the wiper again.
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 ma in beam are switched on and the wind-
screen wiper lever was he ld in the position ⇒page 65, fig. 58 for about 1
second.
The headlight washer nozzles are moved forward out of the bumper by the water
pressure for cleaning the headlights.
You should remove stubborn dirt (such as insect residues) from the headlight
lenses at regular intervals, for example when refuelling. Please refer to the following
guidelines.
You should remove any snow from the fixt ures 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 fo r the windscreen wipers
One cannot fold out the wiper arms in the rest position from the wind-
screen. Before replacing the wiper arms you must put them into the
service position.
Service position for changing wiper blades
– Close the bonnet.
– Switch the ignition on and then again off.
– Then press the windscreen wiper lever in the position ⇒page 65,
fig. 58 within 10 seconds - the wiper arms move into the service posi-
tion.
Taking off the wiper blade
– Fold windscreen wiper arm away from the windscreen.
– Press the locking button, in order to unlock the wiper blade and pull off in the direction of arrow ⇒fig. 59 .
Attaching a wiper blade
– Push the wiper blade until it locks up to the stop.
– Check whether the wiper blade is correctly attached.
– Fold the windscreen wiper arm back onto the windscreen.
The wiper arms return to the rest position after switching on the ignition and
changing the position of the window wiper lever or when driving at a speed greater
than 6 km/h.
Wiper blades in proper condition are esse ntial 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 automatic vehicle wash systems. It is
therefore important to degrease the lips of the wiper blades after every pass
through an automatic vehicle wash system .
