If Adaptive Highbeam Assist is active, it auto-
matically controls activation and deactivation of
the high-beam headlamps (
Ypage 113).

cally if an air bag is deployed.
The hazard warning lamps still operate if the
ignition is switched off.
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.
Cornering light function with traffic circle
function:
The cornering light function is activated on both
sides before entering a traffic circle through an
evaluation of the current GPS position of the
vehicle. It remains active until after the vehicle
has left the traffic circle. In this way, pedestrians
crossing the road, for example, are illuminated
by your vehicle in good time.
Only vehicles with the COMAND multimedia sys-
tem have this function.
Adaptive Highbeam Assist
General notes
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 head-
lamps from high beam to low beam.
Exterior lighting113
Lights and windshield wipers
Z
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.
Important safety notes
GWARNING
Adaptive Highbeam Assist does not recognize
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
On very rare occasions, Adaptive Highbeam
Assist may fail to recognize other road users
that have lights, or may recognize them too
late. In this, or in similar situations, the auto-
matic high-beam headlamps will not be deac-
tivated 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 cannot take into
account road, weather or traffic conditions.
Adaptive Highbeam Assist is only an aid. You are responsible for adjusting the vehicle's lighting
to the prevailing light, visibility and traffic con-
ditions.
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
on/off
XTo switch on: turn the light switch to the
à position.
XPress the combination switch forwards
beyond the pressure point (Ypage 112).
The _ indicator lamp on the multifunction
display lights up when it is dark and the light
sensor switches on the low-beam headlamps. If you are driving at speeds above approx-
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 Kindicator lamp on the
instrument cluster also lights up.
If you are driving at speeds below approx-
imately 16 mph (25 km/h) or other road users are detected or the roads are adequately lit:
The high-beam headlamps are switched off
automatically. The Kindicator lamp on the
instrument cluster goes out. The _indi-
cator lamp on the multifunction display
remains lit.
XTo switch off: move the combination switch
back to its normal position or move the light
switch to another position.
The K indicator lamp on the instrument
cluster goes out.
Headlamps fogged up on the inside
Certain climatic and physical conditions may
cause moisture to form in the headlamp. This
moisture does not affect the functionality of the
headlamp.

Protect bulbs from moisture during operation.
Do not allow bulbs to come into contact with
liquids.
Replace only the bulbs listed (
Ypage 116).
Have the bulbs that you cannot change yourself
replaced at a qualified specialist workshop.
If you require assistance replacing bulbs, con-
sult a qualified specialist workshop.
If the new bulb still does not light up, consult a
qualified specialist workshop.
Headlamps and lights 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.
Vehicles with LED headlamps: the front and
rear light clusters of your vehicle are equipped
with LED bulbs. Do not replace the bulbs your-
self. Contact a qualified specialist workshop
which has the necessary specialist knowledge
and tools to carry out the work required.

Head-up display
General notes
The head-up display projects information from
the navigation system and the driver assistance
system above the dashboard into the driver's
field of vision. The head-up display allows the
driver to see all of the information without hav-
ing to take their eyes off the road.
A requirement for the display of the contents is that the following functions are available in the
vehicle and are switched on:
RCruise control
RDISTRONIC PLUS
RTraffic Sign Assist
RNavigation
Important safety notes
The head-up display is only an aid and is not a
substitute for attentive driving.
The visibility of the head-up display is influencedby the following conditions:
Rthe driver's seat position
Rthe positioning of the display image
Rthe general ambient light
Rsunglasses with polarization filters
Rwet roads
Rblocking of sunlight by objects on the display
cover
In the event of extreme sunlight, sections of the
display may fade. This can be reversed by
switching the head-up display off and on again.
iVehicles with the head-up display are equip-
ped with a special windshield. Should repairs
be necessary, have the windshield replaced at
a qualified specialist workshop.
