Exterior lighting
General notes
For reasons of safety, Mercedes-Benz recom-
mends that you drive with lights switched on
even during the daytime. In some countries,
operation of the headlamps varies due to legal
requirements and voluntary recommendations. Driving abroad
Vehicles with halogen or static LED
headlamps It is not necessary to switch your headlamps to
symmetrical dipped beam when driving in coun- tries where vehicles are driven on the opposite
side of the road to the country in which the vehi-
cle is registered. Legal requirements are fulfilled
without switching the headlamps to symmetri-
cal dipped beam.
Vehicles with Intelligent Light System It is necessary to switch your headlamps to sym-
metrical dipped beam before crossing the bor-
der into countries where vehicles are driven on
the opposite side of the road. This prevents
oncoming traffic from being dazzled.
You can switch the headlamps to symmetrical or
asymmetrical dipped beam using the "dipped-
beam headlamps for driving on the right/left"
function via the on-board computer
(Y page 236). This must be switched back to
asymmetrical dipped beam upon your return.
Symmetrical lights do not illuminate as large an
area of the edge of the carriageway. In this case,
"highway mode" and "extended-range fog
lamps" are not available. Setting the exterior lighting
Setting options Exterior lighting can be set using the:

ogen headlamps (Y page 116)

combination switch, only the indicator lamp
on the corresponding side of the vehicle will
flash.
The hazard warning lamps switch on automati-
cally if:
R an airbag has been triggered or
R the vehicle decelerates rapidly from a speed
of above 70 km/h and comes to a standstill
The hazard warning lamps switch off automati-
cally if the vehicle reaches a speed of above
10 km/h again after a full brake application.
The hazard warning lamps continue to operate
even if the ignition is switched off. Intelligent Light System
General notes The Intelligent Light System is a system that
adjusts the headlamps to suit the prevailing
driving and weather conditions. It offers
advanced functions for improved illumination of
the road surface, e.g. depending on the vehicle
speed or weather conditions. The system
includes the active light function, cornering light
function, motorway mode and extended-range
fog lamps. The system is active only when it is
dark.
You can activate/deactivate the Intelligent Intelligent
Light System
Light System function using the on-board
computer (Y page 235).
Active light function The active light function is a system that moves
the headlamps according to the steering move- ments of the front wheels. In this way, relevant
areas remain illuminated while you are driving.
This allows you to recognise pedestrians,
cyclists and animals sooner.
Active: when the lights are switched on.
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 be acti-
vated only when the dipped-beam headlamps
are switched on. Active:
R if you are driving at speeds below 40 km/h
and switch on the turn signal or turn the steer-
ing wheel
R if you are driving at speeds between 40 km/h
and 70 km/h and turn the steering wheel
The cornering light function may remain lit for a short time, but is automatically switched off
after no more than three minutes.
Motorway mode Motorway mode increases the range of the
beam.
Active:if you are driving at a speed above
110 km/h and do not make any large steering
movements for at least 1000 m or if you are
driving at a speed above 130 km/h.
Not active: if you are driving at speeds below
80 km/h following activation.
Extended range fog lamps The extended-range fog lamps reduce the glare
experienced by the driver and improve the illu-
mination of the edge of the carriageway.
Active: if you are driving at speeds below
70 km/h and you switch on the rear fog lamp.
Not active: if, following activation, you are driv-
ing at speeds above 100 km/h or if you switch
off the rear fog lamp. Adaptive Highbeam Assist Plus
General notes With Adaptive Highbeam Assist Plus, you can
automatically switch between dipped-beam,
partial main-beam and main-beam headlamps.
Partial main-beam illumination is a form of illu-
mination whereby the main beam is directed
past other road users. Other road users are kept
out of the main beam. This prevents glare. If
there is a vehicle in front, for example, the main-
beam headlamps illuminate the areas to its right
and left, and the vehicle in front is illuminated by the dipped-beam headlamps.
The system automatically adapts the dipped-
beam headlamp range depending on the dis-
tance to the other vehicle. Once the system no
longer detects any other vehicles, it switches on the main-beam headlamps again. Exterior lighting
117Lights andwindscreen wipers Z

If the main-beam or partial main-beam head-
lamps are causing too much reflection from traf- fic signs, the lights are automatically dimmed
and glare for the driver caused by the reflectionsis thus avoided.
The system's optical sensor is located behind
the windscreen near the overhead control
panel.
Important safety notes G
WARNING
Adaptive Highbeam Assist Plus does not rec-
ognise 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
Plus may not recognise road users who do
have lights, or may recognise them too late. In this, or in similar situations, the automatic
main-beam headlamps will not be deactivated
or will be activated despite the presence of
other road users. There is a risk of an acci-
dent.
Always carefully observe the traffic conditions and switch off the main-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 in the case of:
R poor visibility, e.g. due to fog, heavy rain or
snow
R dirt on the sensors or obscured sensors Switching Adaptive Highbeam Assist
Plus on/off X
To switch on: turn the light switch to the
à position.
X Press the combination switch forwards
beyond the pressure point (Y page 116).
The indicator lamp _on the multifunction
display lights up when it is dark and the light
sensor switches on the dipped-beam head-
lamps.
At speeds above approx. 25 km/h: the head- lamp range is automatically controlled
according to the distance to other road users.
At speeds above approximately 30 km/h:
R if no other road users are detected, the
main-beam headlamps are automatically
switched on
R if other road users are detected, the partial
main-beam headlamps are automatically
switched on
The K indicator lamp on the instrument
cluster also lights up.
At speeds below approx. 25 km/h or when
there is sufficient street lighting:
R the partial main-beam headlamps are
switched off automatically
R the main-beam headlamps are switched off
automatically
The K indicator lamp on the instrument
cluster goes out. The _indicator lamp on
the multifunction display remains lit.
X To switch off:move the combination switch
back to its normal position or move the light
switch to another position.

General notes The Head-up Display projects information from
the navigation system and the driver assistance
systems above the dashboard into the driver's
field of vision. This way, the Head-up Display
enables drivers to see information without hav-
ing to take their eyes off the road.
A requirement for the display of the content is
that the following functions are available in the
vehicle and are switched on:
R Cruise control
R SPEEDTRONIC
R DISTRONIC PLUS
R Traffic Sign Assist
R Navigation
Important safety notes The head-up display is only an aid and is not a
substitute for attentive driving.
Speed limits and overtaking restrictions are not
always correctly displayed. Traffic signs always
have priority over the Traffic Sign Assist display.
The visibility of the head-up display is influenced by the following conditions:
R the driver's seat position
R the positioning of the display image
R the general light conditions R
sunglasses with polarisation filters
R wet road surfaces
R blocking 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.
