Vehicle equipment
i This manual describes all the standard
and optional equipment of your vehicle
which was available at the time of
purchase. Country-specific differences are
possible. Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
relevant systems and functions.
Exterior lighting
Important safety 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. In these countries, the daytime
running lamps are automatically switched on
when the engine is started.
Information about driving abroad
Converting to symmetrical low beam
when driving abroad: switch the headlamps
to symmetrical low beam in countries in
which traffic drives on the opposite side of the
road to the country where the vehicle is
registered. This prevents glare to oncoming
traffic. Symmetrical lights do not illuminate
as large an area of the edge of the road.
Have the headlamps converted at a qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center, as close to the border
as possible before driving in these countries.
Converting to asymmetrical low beam
after returning: have the headlamps
converted back to asymmetrical low beam at
a qualified specialist workshop, e.g. an
authorized Mercedes-Benz Center, as soon as
possible after crossing the border when
returning.

Halogen bulbs are pressurized and could
explode when you change them, particularly
if they are very hot. You should therefore wear
eye protection and gloves when you are
changing them.
There are bulbs other than the Xenon bulbs
that you cannot replace. Replace only the
bulbs listed ( Y page 97). Have the bulbs that
you cannot replace yourself changed at a
qualified specialist workshop.
Mercedes-Benz recommends that you use an
authorized Mercedes-Benz Center for this
purpose. In particular, work relevant to safety
or on safety-related systems must be carried
out at a qualified specialist workshop.
If you require assistance changing bulbs,
consult a qualified specialist workshop.
Do not touch the glass tube of new bulbs with
your bare hands. Even minor contamination
can burn into the glass surface and reduce
the service life of the bulbs. Always use a lint-
free cloth or only touch the base of the bulb
when installing.
Only use bulbs of the correct type.
If the new bulb still does not light up, consult
a qualified specialist workshop.
Bulbs and lamps 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.
Before changing bulbs
Have the following bulbs changed at a
qualified specialist workshop, e.g. an
authorized Mercedes-Benz Center:
R additional turn signals in the exterior
mirrors
R high-mounted brake lamp
R high-beam/low-beam headlamps (Xenon
bulbs)
R parking lamp/standing lamp
R license plate lamp
i Individual segments of the license plate
lamp LEDs may fail without a display
message appearing in the multifunction
display. Check the license plate lamp
regularly. Consult a qualified specialist
workshop if necessary.
You can replace the following bulbs:
R fog lamp/cornering light with fog lamp

R turn signal lamp (front)
R brake/tail lamp
R turn signal lamp (rear)
