Useful information
iThis 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 notethat your vehicle may
not be equipped with all features
described. This also applies to safety-
related systemsand functions.
iRead the information on qualified
specialist workshops: (Ypage 26).
Exterior lighting
Generalnotes
For reasonsofsafety, Mercedes-Benz
recommends that you drive with the lights
switched on even during the daytime.
Therefore, your vehicle is equipped with
special daytime running lamps. In some
countries, operation of the headlamps varies
due to legal requirements and self-imposed
obligations.
If you wish to drive during the daytime without
lights, switchoff the daytime running lamps
function in the on-board computer
(Ypage 230).
Driving abroad
Symmetrical low-beam headlamps
Switchthe 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 ataqualified
specialist workshop as close to the border as
possible before drivinginthesecountries.
Asymmetrical low beam
Have the headlamps converted back to
asymmetrical low-beam headlamps at a
qualified specialist workshop as soon as
possible after crossing the border again.

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(40km/h)and 45 mph(70km/h)
and turn the steering wheel

Adaptive Highbeam Assist
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. byabarrier
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 isarisk 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 betweenlow 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 detectsany other vehicles,
it reactivates the high-beam headlamps.
The system's optical sensor is located behind
the windshield near the overhead control
panel.
