Risk of accident
Th ev ehicle is braked when th eHOLDfunction
or DISTRONI CPLUSisa ctivated. Therefore,
dea ctivate th eHOLD function and DISTRONIC
PLU Sbefor ethe vehicle is washed in an auto-
matic car wash.
You can wash the vehicle in an automatic car
wash from the ver ystart.
! We recommend automatic car washes
with an adjustable 40
high-pressure pre-
cleaning program. In car washes that use
hig hw ater pressures, there is adanger that
as mall quantity of water may leak int othe
vehicle.
! Cabriolet: do not treat the vehicle with
hot wax under any circumstan ces.
! Cabriolet: pull the key out of the ignition
lock when washing the vehicle .This
ensures that the win ddeflector on the
windscreen is retracted. The wind deflector
may otherwise be damaged.
If the vehicle is ver ydirty, pre-wash it before
cleaning it in an automatic car wash.
! In car washes with atowing mechanism,
make sure that the automatic transmission
is in transmission position N,otherwis ethe
vehicle could be damaged.
! Make sur ethat the side windows ar ecom-
pletel yclosed, that the ventilation/heater
blowe risfully turned off and that the wind-
screen wiper switch is set to 0.Otherwi se,
the rain/light senso rmay be activated, trig-
gering unintended wiper movemen ts.T his
could cau se damage to the vehicle.
After using an automatic car wash, wip eoff
wax from th ewindscreen and the wiper
blades. This will prevent smears and reduce
wiping noises caused by residue on the wind-
screen. High-pressur
ecleaners G
Risk of accident
Do not use high-pressur ecleaners with circu-
lar-jet nozzles (dirt grinders) to clean your
vehicle, in particular the tyres. You could oth-
erwise damage the tyres and cause an acci-
dent.
! Always maintain adistance of at least
30 cm between the vehicle and the high-
pressure cleaner nozzle. Information about
the correct distance is available from the
equipment manufacturer.
Move the high-pressure cleaner nozzle
around when cleaning your vehicle.
Do not aim directly at any of the following:
R tyres
R door joint
R soft top (Cabriolet)
R wind deflector net (Cabriolet)
R electrical components
R battery
R connectors
R lights
R seals
R trim elements
R ventilation slots
Damaged seals or electrical components
can lead to leaks or failures.
Cleanin gthe whee ls !
Do not use acidic whee lcleaning products
to remov ebrake dust .This could damage
wheel bolts and brake componen ts.
! Do not park up the vehicle for an extended
perio dstraight after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosio nofthe brake discs and
brake pads/linings. For this reason, you
should drive for afew minutes after clean-
ing. Brakin gheats the brak ediscs and

essary specialis tknowledge and tool stocarry
out the work required. The faulty tyre must be
replaced in every case.
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose .Inp articular, work relevant to safety or
on safety-related systems must be carried out
at aq ualified specialist workshop.
i Whe nreplacing one or all tyres, make
sure that you only use tyres marked
MOExtended and of the specified size for
the vehicle.
i Vehicles featuring the MOExtended run-
flat system are not equipped with the
TIREFI Tkit. It is therefor erecommended
that you additionally equip your vehicle
with the TIREFI Tkit if you fit tyres that do
not featur erun-flat properties ,e.g. winter
tyres .You can obtain aTIREFIT kit from a
Mercedes-Benz Service Centre ,for exam-
ple. Ba
ttery Important safety notes
In order for the battery to achieve the maxi-
mum possible service life, it must always be
sufficiently charged.
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. To prevent damage from corrosion, only
replace the battery with one that has
acentral
ven tilation cover.
Only replace abattery with abattery that has
been recommended by Mercedes-Benz.
Consult aMercedes-Benz Servic eCentr eif
you wish to leave your vehicle parked up for
al ong period of time. G
Risk of inju
ry

Risk of inju
ry
Fo rs afety reasons, Mercedes-Benz recom-
mends that you only use batteries which have
been tested and approved for your vehicle by
Mercedes-Benz. Thes ebatteries provide
increased impact protection to prevent vehi-
cle occupant sfrom suffering aci dburns
should the battery be damaged in the event
of an accident.
To prevent acid burns, observe the following
safety notes when handling batteries:
R do not lean over the battery.
R do not place any metal objects on abattery.
Otherwise ,you coul dcause ashort circuit
and the battery's gas mixtur ecould ignite.
R mak esure that you do not create an elec-
trostatic charge, e.g. by wearing synthetic
clothing or as aresult of friction on fabrics.
Therefore, you should not pull or slide the
batter yover carpets or other synthetic
materials.
R neve rtouch the battery first. To discharge
ap ossible electrostatic charge, step out of
the vehicle first and touc hthe bodywork.
R do not wipe the battery usin gacloth. The
battery may explode as aresult of electro-
static charge or due to flying sparks.
! Switc hoff th eengine and remove the key
before disconnectin gthe termi nalclamps
from the battery .Onvehicles with KEY-
LE SS -GO, make sure that the ignition is
switched off. Check that all the indicator
lamps in the instrument cluste rare off.
Otherwise, yo umay destroy electronic
components, such as the alternator.
i Remove the key if you park the vehicle
and do not require any electrical consum-
ers. The vehicle will then use very little
energy, thus conserving battery power.
Mercedes-Benz recommends that you do not
carr yout work on batteries yourself, e.g.
removing, charging or replacing. Always have this work performed at
aqualified specialist
workshop, e.g. aMercedes-Ben zService
