Exterior lighting
Important safety notes
For reasons of safety, Mercedes-Benz recom-
mends that you drive with the lights switched
on even during the daytime. In some coun-
tries, operation of the headlamps varies due
to legal requirements and self-imposed obli-
gations.
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 sym-
metrical 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 asym- metrical low-beam headlamps at a qualified
specialist workshop as soon as possible after
crossing the border again.

Replacing bulbs
Important safety notes
GDANGER
Xenon bulbs carry a high voltage. You can get
an electric shock if you remove the cover of
the Xenon bulb and touch the electrical con-
tacts. There is a risk of fatal injury.
Never touch the parts or the electrical con-
tacts of the Xenon bulb. Always have work on
the Xenon bulbs carried out at a qualified spe-
cialist workshop.
GWARNING
Bulbs, lamps and connectors can get very hot when operating. If you change a bulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these components to cool down beforechanging a bulb.
Do not use a bulb that has been dropped or if
its glass tube has been scratched.
92Replacing bulbs
Lights and windshield wipers

The bulb may explode if:
R you touch it
R it is hot
R you drop it
R you scratch it
Only operate bulbs in enclosed lamps
designed for that purpose. Only install spare
bulbs of the same type and the specified volt- age.
Marks on the glass tube reduce the service
life of the bulbs. Do not touch the glass tube
with your bare hands. If necessary, clean the
glass tube when cold with alcohol or spirit and
rub it off with a lint-free cloth.
Protect bulbs from moisture during opera-
tion. Do not allow bulbs to come into contact
with liquids.
Xenon bulbs
If your vehicle is equipped with Xenon bulbs,
you can recognize this by the following: the
cone of light from the Xenon bulbs moves
from the top to the bottom and back again
when you start the engine. For this to be
observed, the lights must be switched on
before starting the engine.
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.
LED lamps
You can replace neither Xenon bulbs nor LED
bulbs. Have LED bulbs changed at 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 replaced at a quali-
fied specialist workshop:
R Additional turn signals in the exterior mir-rors
R High-mounted brake lamp R
High-beam/low-beam headlamps (Xenonbulbs)
R Daytime running lamps
R Parking lamps/standing lamps
R License plate lamp
iIndividual segments of the license plate
lamp LEDs may fail without a display mes-
sage appearing in the multifunction dis-
play. Regularly check the license plate
lamp. If necessary, visit a qualified special-
ist workshop.
You can replace the following bulbs:
R Fog lamp/cornering light with fog lamp
function
R Turn signal lamp (front)
R Brake/tail lamp

that you cannot replace yourself. Only replace the bulbs listed ( Ypage 94). Have the bulbs
that you cannot replace yourself replaced at a
qualified specialist workshop.
If you require assistance replacing bulbs, con-
sult 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.
