the engine is running (Y page 121). When you
switch off the ignition, the automatic
headlamp cleaning system is reset and

113Lights and windshield wipers Z

The active light function is a system that
moves the headlamps according to the
steering movements of the front wheels. In
this way, relevant areas remain illuminated
while driving. This allows you to recognize
pedestrians, cyclists and animals.
Active: when the lights are switched on. Cornering light function
The cornering light function improves the
illumination of the road over a wide angle in
the direction you are turning, enabling better
visibility in tight bends, for example. The
cornering light function can only be activated
when the low-beam headlamps are switched
on.
Active:
R
if you are driving at speeds below
25mph (40 km/h) and switch on the turn
signal or turn the steering wheel.
R if you are driving at speeds between
25 mph (40 km/h) and 45 mph (70 km/h)
and turn the steering wheel.
Not active: if you are driving at speeds above
25 mph (40 km/h) or switch off the turn
signals or turn the steering wheel to the
straight-ahead position.
The cornering light function may remain lit for
a short time, but is automatically switched off
after no more than three minutes. Adaptive Highbeam Assist
G
WARNING
Adaptive Highbeam Assist does not recognize
road users:
R who have no lights, e.g. pedestrians
R who have poor lighting, e.g. cyclists
R whose lighting is blocked, e.g. by a barrier
In very rare cases, Adaptive Highbeam Assist
may fail to recognize other road users that
have lights, or may recognize them too late.
In this or similars ituations, the automatic
high-beam headlamps will not be deactivated
or activated regardless. There is a risk of an
accident.
Always carefully observe the traffic conditions
and switch off the high-beam headlamps in
good time.
You can use this function to set the
headlamps to change betwee nlow beam and
high beam automatically. The system
recognizes vehicles with their lights on, either
approaching from the opposite direction or
traveling in front of your vehicle, and
consequently switches the headlamps from
high beam to low beam.
The system automatically adapts the low-
beam headlamp range depending on the
distance to the other vehicle. Once the
system no longer detects any other vehicles,
it reactivates the high-beam headlamps.
The system's optical sensor is located behind
the windshield near the overhead control
panel. 114

Important safety notes
Xenon bulbs G
DANGER
Xenon bulbs carry a high voltage. You can get
an electric shock if you remove the cover of
the Xenon bulb and touch the electrical
contacts. There is a risk of fatal injury.
Never touch the parts or the electrical
contacts of the Xenon bulb. Always have work
on the Xenon bulbs carried out at a qualified
specialist workshop.
If your vehicle is equipped with Xenon bulbs,
you can recognize this by the following: the
cone of light from the Xenon bulbs moves
from the top to the bottom and back again
when you start the engine. For this to be 116

observed, the lights must be switched on
before starting the engine.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times.
Have the headlamp setting checked regularly.
Other bulbs G
WARNING
Bulbs, lamps and connectors can get very hot
when operating. If you change a bulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these components to cool down before
changing a bulb.
There are bulbs other than the Xenon bulbs
that you cannot replace. Replace only the
bulbs listed (Y page 117). Have the bulbs that
you cannot replace yourself changed at a
qualified specialist workshop.
If you require assistance changing bulbs,
consult a qualified specialist workshop.
Do not touch the glass tube of new bulbs with
your bare hands. Even minor contamination
can burn into the glass surface and reduce
the service life of the bulbs. Always use a lint-
free cloth or only touch the base of the bulb
when installing.
Only use bulbs of the correc ttype.
If the new bulb still does no tlight up, consult
a qualified specialist workshop.

Windshield wipers
Switching the windshield wipers on/

! Do not operate the windshield wipers
whe nthe 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 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.

X Switch on the ignition.
X Turn the combination switch to the

! 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
windshield.
For this reason, you should always switch
off the windshield wipers in dry weather.
In the 0001or0002 position, the appropriate
wiping frequency is set automatically
according to the intensity of the rain. In
the 0002 position, the rain sensor is more
sensitive than in the 0001position, causing
the windshield wipers to wipe more
frequently.
If the wiper blades are worn, the windshield
will no longer be wiped properly. This could
prevent you from observing the traffic
conditions. Replace the wiper blades twice a
year, ideally in spring and fall. Replacing the wiper blades
Important safety notes G
WARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you could
be trapped by the wiper arm. There is a risk
of injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
! Never open the hood if a windshield wiper
arm has been folded away from the
windshield.
Never fold a windshield wiper arm without
a wiper blade back onto the windshield.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release
the windshield wiper arm without a wiper
blade and it falls onto the windshield, the
windshield may be damaged by the force of
the impact.
