Useful information
i This Owner's Manual describes all models
and all standard and optional equipment
available to your vehicle at the time of pub-
lication of the Owner's Manual. Country-
specific deviation sare possible. Please
not ethat your vehicle may not be equipped
with all feature sdescribed. This also
applies to safety-relevan tsystems and
functions.

Important safet
ynotes
Fo rreasons of safety, Mercedes-Benzr ecom-
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 requirement sand self-imposed obli-
gations. Notes on driving abroad
Convert to symmetrical dipped beam
when driving abroad: switch the headlamps
to symmetrical dipped beam in countries in
which traffic drives on the opposite side of the
road to the country where the vehicle is reg-
istered. This prevents glare to oncoming traf-
fic. Symmetrical lights do not illuminate as
large an area of the edge of the carriageway.
Convert the headlamps as close to the border
as possible before driving in these countries
(Y page 227).
Convert to asymmetrical dipped beam
after returning: convert the headlamps back
to asymmetrical dipped beam as soon as pos-
sible after crossing the border when returning
(Y page 227). If the headlamps are converted to symmetri-
cal dipped beam, the "motorway mode" and
"extended range foglamps" function
s(Intelli-
gent Light System )are not available. Light switch

The system may be impaired or deactivated:
R
if there is poor visibility, e.g. due to snow,
rain, fog or spray
R if the area of the windscreen around the
optical sensor is dirty, misted up or covered
up, e.g. by asticker
The system may not recognise the following
road users:
R road users that have no lighting, e.g. pedes-
trians
R road users that have poor lighting, e.g.
cyclists
R road users whose lighting is not clearly visi-
ble, e.g. road users behind acrash barrier
R on rare occasions :road users that have
lights that may be recognised too late or not
at all
The automatic main-beam headlamps will not
be deactivated, or they may be activated
despite road users travelling in front of or
approaching the vehicle.
Thus, you could cause an accident and injure
yourself and others. Always observe traffic
conditions and, if necessary, dip the lights
manually. Headlamps misted up inside
The headlamps may mist up on the inside if
there is high atmospheric humidity.
X Drive with the headlamps switched on.
The level of moisture diminishes, depend-
ing on the length of the journey and the
weather conditions (humidity and temper-
ature).
If the level of moisture does not diminish:
X Have the headlamps checked at aqualified
specialist workshop. Interior lighting

Mercedes-Ben
zrecommends the use of an
approved exterior aerial. This ensures:
R optimal mobile phone reception quality in
the vehicle
R mutual influences between the vehicle
electronics and mobile phones are mini-
mised
An exterior aerial has the following advan-
tages:
R it conducts the electromagnetic fields gen-
erated by awireless device to the exterior.
R the field strengt hinthe vehicle interior is
lower than in avehicle that does not have
an exterior aerial.
