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

Cleaning the plastic trim G
Risk of injury
When cleaning the steering wheel boss and
dashboard, do not use cockpit sprays or
cleaning agents containing solvents. Cleaning
agents containing solvents cause the surface
to become porous, and as aresult plastic
part smay break away and be thrown around
the interior when an airbag is deployed, which
may result in severe injuries.
! Do not affix the following to plastic surfa-
ces:
R stickers
R films
R scented oil bottles or similar items
You can otherwise damage the plastic.
! Do not allow cosmetics, insect repellent
or sunscreen to come in contact with the
plastic trim .This maintain sthe high-quality
look of the surfaces.
X Wipe the plastic trim with adamp, lint-free
cloth, e.g. amicrofibre cloth.
X Heavy soiling: use car care and cleaning
products recommended and approved by
Mercedes-Benz.
The surface may change colour tempora-
rily. Wait until the surface is dry again. Cleanin
greal wood and trim strips X

such as tar remover, wheel cleaners, pol-
ishes or waxes. There is otherwise arisk of
damaging the surface.
Cleanin gthe seat covers !
Do not us emicrofibre cloths to clean gen-
uine leather, artificial leather or
Alcantara ®

damage the cover.
! Observ ethe followin gwhen cleaning:
R clea ngenuin eleather covers carefully
with adamp cloth and then wipe the cov-
ers down with adry cloth .Make sure that
the leather does not become soaked .It
may otherwise become rough and
cracked .Only use leather care agents
that have bee ntested and approved by
Mercedes-Benz. You can obtain these
from aqualified specialist workshop, e.g.
aM ercedes-Ben zService centre.
R clean artificial leather covers with acloth
moistened with asolution con taining 1%

R When parking your vehicle, make sure that
the tyres do not ge tdeformed by the kerb
or other obstacles. If it is necessary to drive
over kerbs, speed humps or simila releva-
tions, try to do so slowly and at an obtuse
angle. Otherwise, the tyres, particularly the
sidewalls, can get damaged. Maintenance and care of wheels and
tyres
Checking wheels and tyres
R Regularly chec kthe wheels and tyres of
your vehicle for damage (e.g. cuts, punctu-
res, tears, bulges on tyres and deformation,
crack sorseverecorrosion on wheels), at
least ever y14d ays, as well as after driving
off-road or on rough roads. Damaged
wheels can cause aloss of tyr epressure.
R Regu larly check th etyre tread depth and
the conditio nofthe tread across the whole
widt hofthe tyr e(Ypage 299). If neces-
sary, tur nthe front wheels to full lock in
orde rtoi nspect the inner sid eofthe tyre
surface.
R All wheels must hav eavalve cap to protect
the valve against dirt and moisture. Do not
fit anything onto the valve (such as tyre
pressure monitorin gsystems) othe rthan
the standar dvalve cap or other valve caps
approved by Mercedes-Ben zfor your vehi-
cle.
R Regularly chec kthe pressur eofall the tyres
including the emergenc yspare wheel or the
spare wheel, particularly prior to long trips,
and correc tthe pressur easnecessary
(Y page 299). Ty
re tr ead G
Risk of accident
Bear in mind that:
R tyre grip decreases rapidly on wet roads
when the tread depth is less than 3mm.
Thus ,you should repl acet yres that have
insufficient tread.
R winter tyres sho uld bereplaced when the
trea ddepth is 4mmorl ess as they will no
longer provide adequat egrip.
R thet rea donat yre may not wear evenly.
Thus ,you should regularly chec kthe tread
depth and the condition of the tread across
the entire widt hofall tyres. If necessary,
turn the steerin gwheel so that you can see
the tyr etrea dm ore easily.
You coul dotherwise los econtrol of the vehi-
cle and cause an acciden tdue to the reduced
grip of the tyres on the road. Storing tyres
Store tyres that are not being used in acool,
dry and preferably dar kplace. Protect the
tyres against oil, grease, petrol and diesel. Cleaning tyres
! Do not use ahigh pressure jet with circu-
lar jet nozzles (concentrated-power jets) to
clean the tyres. The high pressure of the
water jet could damage the tyres. Always
replace damaged tyres. Tyr
epressures Recommended ty
repressures
You will find atable of tyre pressures for var-
ious operating conditions on the inside of
your vehicle's fuel filler flap.
The applicable value for the emergency spare
wheel is stated on the spare wheel and in the
