Cornering light function
The cornering light function improves the illu-
mination of the road over a wide angle in the
direction you are turning, enabling better visi-
bility in tight bends, for example. It can only be
activated when the low-beam headlamps are
switched on.
Active:
Rif you are driving at speeds below 25 mph
(40 km/h) and switch on the turn signal or
turn the steering wheel
Rif you are driving at speeds between 25 mph
(40 km/h) and 45 mph (70 km/h) and turn
the steering wheel
The cornering lamp may remain lit for a short
time, but is automatically switched off after no
more than three minutes.
Adaptive Highbeam Assist Plus
General notes
With Adaptive Highbeam Assist Plus, you can
automatically switch between low-beam, partial
high-beam and high-beam headlamps.
Partial high-beam is a form of illumination
whereby the high-beam is directed past other
road users. Other road users are kept out of the
high-beam. This prevents glare. When there is a
vehicle in front, for example, the high-beam
headlamps illuminate the areas to its right and
left. The vehicle in front is illuminated by the low-
beam headlamps.
The system automatically adapts the low-beam
headlamp range depending on the distance to
the other vehicle. Once the system no longer
106Exterior lighting
Lights and windshield wipers

detects any other vehicles, it reactivates the
high-beam headlamps.
If the reflected light from the high-beam head-
lamps or partial high-beam headlamps from traf-
fic signs is too strong, the lights are automati-
cally dimmed. Glare for the driver caused by the
reflections is thus avoided.
The system's optical sensor is located behind
the windshield near the overhead control panel.
Important safety notes
GWARNING
Adaptive Highbeam Assist Plus does not react
to road users:
Rwho have no lights, e.g. pedestrians
Rwho have poor lighting, e.g. cyclists
Rwhose lighting is blocked, e.g. by a barrier
In very rare cases, Adaptive Highbeam Assist
Plus may not react to road users who do have
lights, or may recognize them too late. In this,
or in similar situations, the automatic high-
beam headlamps will not be deactivated or
will be 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.
Adaptive Highbeam Assist Plus cannot take into
account road, weather or traffic conditions.
Adaptive Highbeam Assist Plus is only an aid.
You are responsible for adjusting the vehicle's
lighting to the prevailing light, visibility and traf-
fic conditions.
In particular, the detection of obstacles can be
impaired if:
Rthere is poor visibility, e.g. due to fog, heavy
rain or snow
Rthere is dirt on the sensors or anything else
covering the sensors
Switching Adaptive Highbeam Assist
Plus on/off
XTo switch on: turn the light switch to the

imately 16 mph (25 km/h):
The headlamp range is set automatically
depending on the distance between the vehi-
cle and other road users.
If you are driving at speeds above approx-
imately 19 mph (30 km/ h)and no other road
users are detected:
The high-beam headlamps are switched on
automatically. The 0057indicator lamp on the
instrument cluster also lights up.
If other road users are detected, the partial
high-beam headlamps are automatically
switched on.
If you are driving at speeds below approx-
imately 16 mph (25 km/h) or the roads are
adequately illuminated:
