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/rear window is dry,
as this could damage the wiper blades.
Moreover, dust that has collected on the
windscreen/rear window can scratch the
glass if wiping takes place when the wind-
screen/rear window is dry.
If it is necessary to operate the windscreen
wipers/rear window wiper in dry weather
conditions, always use washer fluid.
! If the windscreen wipers leave smears on
the windscreen/rear window after the vehi-
cle has been washed in an automatic car
wash, this may be due to wax or other res-
idue. Clean the windscreen/rear window
with washer fluid after an automatic 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

In order for the battery to achieve the maxi-
mum possible service life, it must always be
sufficiently charged.
Comply with safety precautions and take pro-
tective measures when handling batteries. WARNING
Avoid the creation of sparks and
heat.
Avoid fire, naked flames and smok-
ing. Creation of sparks.
Battery acid is caustic.
Avoid contact with the skin, eyes
or clothing.
Wear eye protection.
Keep childre
naway. Observe this Owner's Manual.
The vehicle battery, like other batteries, can
discharge over time if you do not use the
vehicle. In such cases, have the battery dis-
connected at a qualified specialist workshop.
You can also charge the battery with a
charger recommended by Mercedes-Benz.
For more information, please contac taquali-
fied specialist workshop.
Explosive gases are created during charging
and jump-starting.
For safety reasons, Mercedes-Benz recom-
mends that you only use batteries which have
been tested and approved for your vehicle by
Mercedes-Benz .These batteries provide
increased impact protection to prevent vehi-
cle occupants from suffering acid burns
should the battery be damaged in the event
of an accident.
Have the battery charge checked more fre-
quently if you use the vehicle mainly for short trips or if you leave it standing idle for a
lengthy period. Consult a qualified specialist
workshop if you wish to leave your vehicle
parked up for a long period of time.
i
When you park the vehicle, remove the
key if you do not require any electrical con-
sumers. The vehicle will then use very little
energy, thus conserving battery power.
i If the power supply has been interrupted,
e.g. due to a discharged battery, you will
have to:
R set the clock. Information on setting the
clock can be found in the separate oper-
ating instructions.
On vehicles with COMAND Online and a
navigation system, the clock is set auto-
matically.
R reset the head restraints on the front
seats (Y page 93).
R reset the function for folding the exterior
mirrors in/out automatically, by folding
the mirrors out once (Y page 100). Charging the battery

WARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is a
risk of an explosion.
Particularly avoid fire, naked flames, creating
sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting.
Do not lean over a battery. G
WARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with the skin, eyes or clothing.
Do not inhale any battery gases. Do not lean
over the battery. Keep children away from
