ynotes
For reasons of safety, Mercedes-Ben zrecom-
mends that you driv ewith the lights switched
on even during the daytime. In some coun-
tries, operation of the headlamps varies due
to legal requirement sand self-imposed obli-
gations. In these countries, the daytime driv-
ing lights are automatically switche donwhen
the engin eisstarted. Notes on driving abroad
Converting to symmetrical dipped beam
when drivin gabroad: switch the headlamps
to symmetrical dipped beam in countries in
which traffic drives on the opposite side of the
road to the countr ywhere the vehicle is reg-
istered. This prevents oncomi ngtraffic from
being dazzled .Symmetrical lights do not illu-
minate as large an area of the edg eofthe
carriageway.
Convert the headlamps as close to the border
as possible before drivin ginthese countries
(Y page 206).
Converting to asymmetrica ldipped beam
after retu rning: conver tthe headlamps back
to asymmetrical dipped beam as soon as pos-
sible after crossing the border when returning
(Y page 206).
Vehicle swith Intelligent Light System: if
the headlamps are converted to symmetrical
dipped beam, not all light functions are avail- able. "Motorway mode" and the "extended
range foglamps" are deactivated. Light switch

Changing bulbs
Important safety notes
Xenon bulbs If your vehicle is equipped wit
hxenon bulb s,
you ca nrecognise this by th efollowing: the
cone of light from th exenon bulbs moves
from th etop to the bottomand back again
whe nyou star tthe engine. Fo rthis to be
observed ,the lights must be switched on
before startin gthe engine. G
Risk of injury
Xenon bulb scarry ahigh voltage. You could
get an electric shock and be seriously or even
fatally injured if you touch the electric con-
tacts on xenon bulbs. Therefore, never
remov ethe cover from xenon bulbs.
Do not change xenon bulbs yourself, but have
them replaced at aqualified specialist work-
sho pwhich has the necessar yspecialist
knowledge and tools to carry out the work
required.
Mercedes-Ben zrecom mends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at aq ualified specialist workshop.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that thes efunction correctly at all times.
Have the headlamp setting checked regularly.

Risk of injury
Bulbs and lights can become very hot. For this
reason, allow them to cool down before
changin gthem. Otherwise, you coul dburn
yourself when you touch them.
Keep bulbs out of the reach of children. Oth-
er wise ,they could damage them, for example,
and inj uret hemselves.
Never use abulbw hich ha sbeend ropped.
Suc hab ulbm ay explod eand injure you. Halogen bulb
sare pressu rised and could
explode when yo uchange them, especiall yif
the yarever yhot. Yo ushould therefor ewear
eye protec tion 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 113). Hav ethe bulbs that
you cannot replac eyourself changed at a
qualified specialist workshop.
Mercedes-Ben zrecom mends that you use a

If you require assistanc echangi ngbulbs, con-
sult aqualified specialist workshop.
Do not touch the glass tube of new bulbs with
your bare hands. Even minor contamination
can burn int othe glass surface and reduce
the servic elife of the bulbs. Always use alint-
free clot horonly touch the bas eofthe bulb
when fit ting.
Only use bulb softhe cor rect type.
If the new bul bstill doe snot light up, consult
