RNING
The windscree nwill 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 twic
eayear, 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
scratc hthe glass if wipin gtakes 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 washe rfluid.
! 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. Clean the
windscreen with washer fluid after an auto-
matic car wash.
! Intermit tentwiping 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 scratc hthe wind-
screen.
For this reason, you should always switch
off the windscreen wiper sind ry weather. Combinatio

Alway suseasuitabl ecoolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the engin ecooling system is not
sufficiently protected from corrosion and
overheating.
! The engin ecooling system is filled with
coolant, which must be renewed after
15 years or after 250,000 kilometres at the
latest.
The coolant is amixtur eofw ater and anti-
freeze/corrosio ninhibitor. It performs the
following tasks:
R anti-corrosio nprotection
R antifreeze protection
R raising th eboiling point
If antifreeze/ corrosion inhibitor is presen tin
the correct concentration, the boil ingp oint of
the coolant during operation will be approx-
imately 13 0†.
The antifreeze/ corrosion inhibitor concentra-
tion in the engin ecooling system should:
R be at least 50%. This will protect the engine
coolin gsystem against freezing down to
approximatel y-37 †.
R not exceed 55% (antifreeze protection
down to -45 †). Hea twill otherwise not be
dissipated as effectively.
If the vehicle has lost coolant, top it up with
equa lamounts of water and antifreeze/cor-
rosio ninhibitor. Mercedes-Benz recom-
mends an antifreeze/corrosion inhibito rcon-
cen trate in accordance with MB Specifica-
tions for Service Products 310.1.
The coolant is checked at every maintenance
interval at aqualified special istworkshop.

led with acoolant mixtur ethat ensures

tion. Windscreen washe
