Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos-

ist workshops: (Y page 23). 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
General notes If your journey takes you to countries where
vehicles are driven on the opposite side of the
road to the country in which the vehicle is
registered, your headlamps must be switched
to symmetrical dipped beam as soon as pos-
sible after crossing the border. This prevents
oncoming traffic from being dazzled. Sym-
metrical lights do not illuminate as large an
area of the edge of the carriageway. Vehicles with halogen headlamps X
Switch off the lights.
X Open the bonnet.
X Turn housing cover :anti-clockwise and
pull it out.
X Push switchover lever ;down.
X Insert housing cover :and turn it clock-
wise.
Conver tthe headlamps back to asymmetrical
dipped beam as soon as possible after return-
ing across the border.
Vehicles with Intelligent Light System X
Before crossing the border, set the head-
lamps to symmetrical dipped beam and
when returning to asymmetrical dipped-
beam using the "Dipped-beam headlamps
for driving on the right or left" function on
the on-board computer (Y page 243).
If the headlamps are converted to symmetri-
cal dipped beam, the "motorway mode" and
"extended range foglamps" functions are not
available. Setting the exterior lighting

Switching the windscreen wipers on/

WARNING
The windscreen will not longer be wiped prop-
erly if the wiper blades are worn. This could
prevent you from observing the traffic condi- tions, thereby causing an accident. Replace
the wiper blades twice a year, ideally in spring
and autumn.
! Do not operate the windscreen wipers
when the windscreen is dry, as this could
damage the wiper blades. Moreover, dust
that has collected on the windscreen can
scratch the glass if wiping takes place when
the windscreen is dry.
If it is necessary to switch on the wind-
screen wipers in dry weather conditions,
always operate them using washer fluid.
! If the windscreen wipers leave smears on
the windscreen after the vehicle has been
washed in an automatic car wash, this may
be due to wax or other residue. Cleant he
windscreen with washer fluid after an auto-
matic car wash.
! Intermittent wiping with rain sensor: due
to optical influences and the windscreen
becoming dirty in dry weather conditions,
the windscreen wipers may be activated
inadvertently. This could damage the wind-
screen wiper blades or scratch the wind-
screen.
For this reason, you should always switch
off the windscreen wipers in dry weather. Combination switch

screen wipers to wipe more frequently. Replacing the wiper blades
Important safety notes G
WARNING
The wiper arms could start moving and cause
an injury if you leave the windscreen wipers
switched on.
Remove the key from the ignition lock before
replacing the wiper blades.
! Never open the bonnet if a windscreen
wiper arm has been folded away from the
windscreen.
Never fold a windscreen wiper arm without
a wiper blade back onto the windscreen.
Hold the windscreen wiper arm firmly when
you change the wiper blade.Ify ou release
the windscreen wiper arm without a wiper
blade and it falls onto the windscreen, the
windscreen may be damaged by the force
of the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at aqualified
specialist workshop.

blades, make sure that you touch only the
wiper arm of the windscreen wiper. Replacing the wiper blades Removing the wiper blades

sports mode
General notes The most important part of the dynamic han-
dling package with sports mode is the adjust-
able damping system. This automatically con-
trols and adapts the suspension to the
respective driving situation.
The calibration of the suspension depends
on:
R
your driving style
R the road surface conditions
R your individual selection; see the following
description
If your vehicle is equipped with automatic
transmission, the dynamic handling package
with sports mode also includes steering
wheel gearshift paddles (Y page 170) with a
manual drive program (Y page 171).
Sports tuning Example: position of dynamic handling package
with sports mode button
The firmer setting of the suspension tuning in
sports mode ensures even better contact Driving systems
