General Notes
H
Environmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible man-
ner.
! For cleaning your vehicle, do not use any
of the following:
R dry, rough or hard cloths
R abrasive cleaning agents
R solvents
R cleaning agents containing solvents
Do not scrub.
Do not touch the surfaces or protective
films with hard objects, e.g. a ring or ice
scraper. You could otherwise scratch or
damage the surfaces and protective film.
! Do not park up the vehicle for an extended
period straight after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked up.
Regular care of your vehicle is a condition for
retaining the quality in the long term. Use care products and cleaning agents rec-
ommended and approved by Mercedes-Benz. Washing the vehicle and cleaning the
paintwork
Automatic car wash G
WARNING
Braking efficiency is reduced after washing
the vehicle. This could cause an accident. For
this reason, following a car wash, drive with
particular care until the brakes are dry. G
WARNING
The vehicle is braked when the HOLD function
or DISTRONIC PLUS is activated. Therefore,
deactivate the HOLD function and DISTRONIC
PLUS before the vehicle is washed in an auto-
matic car wash.
! Preferably use car washes with adjustable
high-pressure jets for pre-washing. This
corresponds with the specifications for
cabriolet programmes. In car washes that
use high water pressures, there is a risk
that a small amount of water may leak into
the vehicle.
! Cabriolet: do not treat the vehicle with
hot wax under any circumstances.
! Cabriolet: pull the key out of the ignition
lock when washing the vehicle. This
ensures that the wind deflector on the
windscreen is retracted. The wind deflector
may otherwise be damaged.
! Make sure that:
R the side windows and sliding sunroof or
soft top are closed completely.
R the blower for the ventilation/heating is
switched off (OFF button is depressed).
R the windscreen wiper switch is at posi-
tion 0.
The vehicle could otherwise be damaged. 312
CareMaintenance and care

!
Make sure that the automatic transmis-
sion is in position Nwhen washing your
vehicle in a tow-through car wash. The vehi-
cle could be damaged if the transmission is
in another position.
You can wash the vehicle in an automatic car
wash from the very start.
Wash off excess dirt before cleaning the vehi-
cle in an automatic car wash.
After using an automatic car wash, wipe off
wax from the windscreen and the wiper
blades. This will prevent smears and reduce
wiping noises caused by residue on the wind-
screen.
Washing by hand In some countries, washing by hand is only
allowed at specially equipped washing bays.
Observe the legal requirements for each indi-
vidual country.
X Do not use hot water and do not wash the
vehicle in direct sunlight.
X Use a soft sponge to clean.
X Use a mild cleaning agent, such as a car
shampoo approved by Mercedes-Benz.
X Thoroughly hose down the vehicle with a
gentle jet of water.
X Do not point the water jet directly towards
the air inlet.
X Use plenty of water and rinse out the
sponge frequently.
X Rinse the vehicle with clean water and dry
thoroughly with a chamois.
X Do not let the cleaning agent dry on the
paintwork.
When using the vehicle in winter, remove all
traces of road salt deposits carefully and as
soon as possible.
High-pressure cleaning equipment G
WARNING
Do not use high-pressure cleaners 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 a distance 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 gaps, joints etc.
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.
Cleaning the paintwork !
Do not affix:
R stickers
R films
R magnetic plates or similari tems
to painted surfaces .You could otherwise
damage the paintwork.
Scratches, corrosive deposits, areas affected
by corrosion and damage caused by inade-
quate care cannot always be completely
repaired. In such cases, visit a qualified spe-
cialist workshop.
X Remove impurities immediately, where
possible, whilst avoiding rubbing too hard.
X Soak insect remains with insect remover
and rinse off the treated areas afterwards. Care
313Maintenance and care Z

X
Soa kbird droppings with water and rinse
off the treated areas afterwards.
X Remove coolant, brake fluid, tree resin,
oils, fuels and greases by rubbing gently
with a cloth soaked in petroleum ether or
lighter fluid.
X Use tar remover to remove tar stains.
X Use silicone remover to remove wax.
Care and treatment of matt paintwork !
Neve rpolish the vehicle or the light alloy
wheels. Polishing makes the paintwork
shiny.
! The following may cause the paint to
become shiny and thus reduce the matt
effect:
R Vigorous rubbing with unsuitable mate-
rials.
R Frequent use of car washes.
R Washing the vehicle in direct sunlight.
! Never use paint cleaner, buffing or pol-
ishing products, or gloss preserver, e.g.
wax. These products are only suitable for
high-gloss surfaces. Their use on vehicles
with matt finish leads to considerable sur-
face damage (shiny, spotted areas).
Always have paintwork repairs performed
at a qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre.
! Do not use wash programs with a hot wax
treatment under any circumstances.
Observe these notes if your vehicle has a
clear matt finish. This will help you to avoid
damage to the paintwork due to incorrect
treatment.
These notes also apply to light-alloy wheels
with a clear matt finish.
i The vehicle should preferably be washed
by hand using a soft sponge, car shampoo
and plenty of water. i
Use only insect remover and car shampoo
from the range of recommended and
approved Mercedes-Benz care products. Cleaning vehicle parts
Cleaning the Cabriolet soft top !
Never use any of the following to clean the
soft top:
R petrol
R thinner
R tar or stain remover
R other organic solvents
! Remove bird droppings immediately as
they are corrosive and, therefore, can make
the soft-top fabric leak. Do not use high-
pressure cleaning equipment to clean the
vehicle. Do not use sharp-edged equipment
to remove ice and snow.
X Light soiling: you can clean the soft top
while it is dry or rinse it with clear water.
X Normal to heavy soiling: clean the roof
with a brush and clear water. Clean stains
and other dirt with a brush and a Mercedes-
Benz recommended and approved cleaning
agent. Always brush from front to back in
the direction of the fabric.
Frequent cleaning reduces the soft top's
resistance to dirt.
To restore this resistance to dirt, clean the
soft top using soft-top cleaning agents that
have been recommended and approved by
Mercedes-Benz.
Incorrect cleaning and care, as well as ageing,
can cause the soft-top seams to leak. Have
the soft-top seams sealed at a qualified spe-
cialist workshop, e.g. at a Mercedes-Benz
Service Centre.
i Cover the soft top appropriately if you
plan to leave the vehicle outside for a long
period of time. 314

Raising the vehicle
G
WARNING
If you do not position the jack correctly at the
appropriate jacking point of the vehicle, the
jack could tip ove rwith the vehicle raised.
There is a risk of injury.
Only position the jac katthe appropriate jack-
ing point of the vehicle. The base of the jack
must be positioned vertically, directly under
the jacking point of the vehicle.
The following must be observed when raising
the vehicle:
R to raise the vehicle, only use the vehicle-
specific jack that has been tested and
approved by Mercedes-Benz. If the jack is
used incorrectly, it could tip over while the
vehicle is raised.
R the jack is designed only to raise and hold
the vehicle for a short time while a wheel
is being changed. It is not suited for per-
forming maintenance work under the vehi-
cle.
R avoid changing the wheel on uphill and
downhill slopes.
R before raising the vehicle, secure it from
rolling away by applying the parking brake
and inserting wheel chocks. Never disen-
gage the parking brake while the vehicle is
raised.
R the jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a
large, load-bearing underlay must be used.
On a slippery surface, a non-slip underlay
must be used, e.g. rubber mats.
R do not use wooden blocks or similar
objects as a jack underlay.O therwise, the
jack will not be able to achieve its load-
bearing capacity due to the restricted
height.
R make sure tha tthe distance between the
underside of the tyres and the ground does
not exceed 3 cm.
R never place your hands or feet under the
raised vehicle. R
never lie under the raised vehicle.
R never start the engine when the vehicle is
raised.
R never open or close a door or the boot lid
when the vehicle is raised.
R make sure that no persons are present in
the vehicle when the vehicle is raised. X
Using wheel wrench :, loosen the bolts on
the wheel you wish to change by about one
full turn. Do not unscrew the bolts com-
pletely. Jacking points (example: Coupé)
The jacking points are located just behind the
front wheel arches and just in front of the rear
wheel arches (arrows).

If antifreeze comes into contact with hot
engine parts, it may ignite and you could burn
yourself. Do not spill any antifreeze on hot
engine parts.
! Only add coolant that has been premixed
with the desired antifreeze protection. You
could otherwise damage the engine.
Further information on coolants can be
found in the Mercedes-Benz Specifications
for Service Products, MB Specifications for
Service Products 310.1, e.g. on the Inter-
net at http://bevo.mercedes-benz.com.
Or contact a qualified specialist workshop.
! Always use a suitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosion and
overheating.
! The engine cooling system is filled with
coolant, which must be renewed after
15 years or after 250,000 kilometres at the
latest.
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
R anti-corrosion protection
R antifreeze protection
R raising the boiling point
If antifreeze/corrosion inhibitor is present in
the correct concentration, the boiling point of
the coolant during operation will be around
130 †.
The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should:
R be at least 50 %. This will protect the engine
cooling system against freezing down to
around -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
equal amounts of water and antifreeze/cor- rosio
ninhibitor. Mercedes-Benz recom-
mends an antifreeze/corrosion inhibito rcon-
centrate in accordance with MB Specifica-
tions for Service Products 310.1.
The coolant is checked at every maintenance
interval at a qualified specialist workshop.
i When the vehicle is first delivered, it is fil-
led with a coolant mixture that ensures
adequate antifreeze and corrosion protec-
tion. Windscreen and headlam
