the necessary service work has been carried
out.
You can obtain further information, e.g.
regarding service work, fro maMercedes-
Benz Service Centre or directly from
Mercedes-Benz.
! If the ASSYST PLUS service interval dis-
play has been inadvertently reset, this set-
ting can be corrected at a Mercedes-Benz
Service Centre.
Have service work carried out as described
in the Service Booklet. This may otherwise
lead to increased wear and damage to the
major assemblies or the vehicle.
Driving abroad
An extensive Mercedes-Benz Service network
is also available in other countries. The
Service Hotline's current telephone numbers
for use when you are abroad are to be found
in the "Mercedes-Benz Service24h" section
of the Service Booklet. Care
Notes on care
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.
! 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. H
Environmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible man-
ner.
! 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. Care of the exterior
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.
You can wash the vehicle in an automatic car
wash from the very start.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
! 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.
! Make sure that:
R the side windows and sliding sunroof 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.
After using an automatic car wash, wipe off
wax from the windscreen and the wiper Care
327Maintenance and care Z

X
Remove coolant, brake fluid, tree resin,
oils, fuels and greases by rubbing gently
with a cloth soaked in petroleum ether or
lighte rfluid.
X Use tar remover to remove tar stains.
X Use silicone remover to remove wax.
! Do not affix:
R stickers
R films
R magnetic plates or similar items
to painted surfaces. You could otherwise
damage the paintwork.
Care and treatment of matt paintwork If your vehicle has a clear mat
tfinish, observe
the following instructions in order to avoid
damage to the paintwork due to incorrect
care.
These notes also apply to light alloy wheels
with a clear mat tfinish.
! 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. 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 the windows G
WARNING
Switch off the windscreen wipers and remove
the key from the ignition lock before cleaning
the windscreen or the wiper blades. On vehi-
cles with KEYLESS-GO, press the Start/Stop
button repeatedly until all indicator lamps in
the instrument cluster have gone off. The
windscreen wipers could otherwise move and
injure you.
! Only fold the windscreen wipers away
from the windscreen when vertical. Other-
wise, you will damage the bonnet.
X Clean the inside and outside of the win-
dows with a damp cloth and a cleaning
agent that is recommended and approved
by Mercedes-Benz.
! Do not use dry cloths, abrasive products,
solvents or cleaning agents containing sol-
vents to clean the inside of the windows.
Do not touch the insides of the windows
with hard objects, e.g. an ice scraper or
ring. There is otherwise a risk of damaging
the windows.
! Clean the water drainage channels of the
windscreen and the rear window at regular
intervals. Deposits such as leaves, petals
and pollen may under certain circumstan-
ces prevent water from draining away.T his
can lead to corrosion damage and damage
to electronic components.

therefore strongly recommended to observe
regular oil changes using an approved engine
oil with the appropriate SAE classification. Brake fluid
G
WARNING
Ove raperiod of time, the brake fluid absorbs
moisture from the air; This lowers its boiling
point.
If the boiling point of the brake fluid is too low,
vapour pockets may form in the brake system
when the brakes are applied hard (e.g. when
driving downhill). This impairs braking effi-
ciency.
You should have the brake fluid renewed at
regular intervals. The brake fluid change inter-
vals can be found in the Service Booklet.
Only use brake fluid approved by Mercedes-
Benz. Information about approved brake flu-
ids can be obtained from any Mercedes-Benz
Service Centre or on the Internet at
http://bevo.mercedes-benz.com
i There is usually a notice in the engine
compartment to remind you when the next
brake fluid change is due. Coolant
Important safety notes 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
i When the vehicle is first delivered, it is fil-
led with a coolant mixture that ensures
adequate antifreeze and corrosion protec-
tion.
! Only add coolant that has been premixed
with the desired antifreeze protection. The
engine could otherwise be damaged.
Further information on coolants and on fill-
ing can be found in the Mercedes-Benz
Specifications for Service Products, MB
Approval 310.1, e.g. on the Internet at
http://bevo.mercedes-benz.com .You can
also consult a Mercedes-Benz Service
Centre.
! 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.
If antifreeze/corrosion inhibitor is present in
the correc tconcentration, 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 protec tthe engine
cooling system against freezing down to
around -37 †.
R not exceed 55% (antifreeze protection
down to -45 †); otherwise, heat will not be
dissipated as effectively.
If the vehicle has lost coolant, top it up with
equal amounts of water and antifreeze/cor- Service products and capacities
