Lights 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 too recognize other road users that
have lights, or may recognize them too late.
In this or similar situations, 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 between low 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

lights up.
If you are driving at speeds above
approximately 28 mph (45 km/h):
The headlamp range is set automatically
depending on the distance between the
vehicle and other road users.
If you are driving at speeds above
approximately 35 mph (55 km/h) and no
other road users have been detected:
The high-beam headlamps are switched on
automatically. The 0057 indicator lamp in
the instrument cluster also lights up.
If you are driving at speeds below
approximately 30 mph (45 km/h) or other
road users have been detected or the roads
are adequately lit:
The high-beam headlamps are switched off
automatically. The 0057 indicator lamp in
the instrument cluster goes out. The 00CEindicator lamp in the instrument cluster
stays on.
X To deactivate: move the combination
switch back to its normal position.
The 00CE indicator lamp in the instrument
cluster goes out. Headlamps fogged up on the inside
The headlamps may fog up on the inside if
there is high atmospheric humidity.
X Switch on the lights and drive off.
The level of moisture diminishes,
depending on the length of
the journey and
the weather conditions (humidity and
temperature).
If the level of moisture does not diminish:
