Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.
i Read the information on qualified
specialist workshops: (Y page 27).Exterior lighting
General notes
For reasons of safety, Mercedes-Benz
recommends that you drive with the lights
switched on even during the daytime. In some
countries, operation of the headlamps varies
due to legal requirements and self-imposed
obligations. Notes on driving abroad
Conversion to symmetrical low beam Switch the headlamps to symmetrical low
beam in countries in which traffic drives on
the opposite side of the road from the country
where the vehicle is registered. This prevents
glare to oncoming traffic. When using
symmetrical lights, the edge of the road is not
lit as widely and as far ahead as normal.
Have the headlamps converted at a qualified
specialist workshop as close to the border as
possible before driving in these countries.
Conversion to asymmetrical low beam
after returning Have the headlamps converted back to
asymmetrical low-beam headlamps at a
qualified specialist workshop as soon as
possible after crossing the border again. Setting the exterior lighting

visibility of your vehicle during the day. To do
this, the daytime running lamps function must
be switched on using the on-board computer
(Y page 231).
If the engine is running and you turn the light
switch to TorL, the manual settings
take precedence over the daytime running
lamps.
Low-beam headlamps G

Exterior lightingLights and windshield wipers

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
Important safety notes 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 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.
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 conditions.
In particular, the detection of obstacles can
be restricted if there is:
R poor visibility, e.g. due to fog, heavy rain or
snow
R dirt on the sensors or the sensors are
obscured
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 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 the116
Exterior lightingLights and windshield wipers

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. Switching Adaptive Highbeam Assist

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
Kindicator 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 Kindicator lamp in
the instrument cluster goes out. The _
indicator lamp in the multifunction display
remains lit.
X To deactivate: move the combination
switch back to its normal position.
