Servicing the brakes
!If the red brake warning lamp lights up in
the instrumentcluster and you hear a
warningtonewhile the engine is running,
the brakefluid level may be too low.
Observe additional warningmessages in
the multifunction display.
The brakefluid level may be too low due to
brakepad wear or leakingbrakelines.
Have the brakesystem checked
immediately. This work should be carried
out ataqualified specialist workshop.
!Vehicles with 4MATIC:function or
performancetests may only be carried out
ona2-axle dynamometer. If you are
planning to have the vehicle tested on such
adynamometer, contactanauthorized
Mercedes-BenzCenter to obtain further
information first. Otherwise, you could
damage the drive train or the brakesystem.
!Vehicles with 4MATIC:as the ESP®
system operates automatically, the engine
and the ignition must be switched off
(SmartKey in position0or1in the ignition
lock or Start/Stop button in position0or

All checksand maintenance work on the
brakesystem must be carried out at a
qualified specialist workshop. Consult a
qualified specialist workshoptoarrangethis.
Havebrakepads installed and brakefluid
replacedataqualified specialist workshop.
If thebrakesystem has only been subject to
moderateloads,you should test the
functionalityofyour brakes at regular
intervals. To do so, press firmly on thebrake
pedal when driving atahigh speed. This
improvesthegripofthebrakepads.
You can findadescription of Brake Assist
(BAS) on (Ypage 67)orofBASPLUSon
(Ypage 67).
The braking characteristics of thevehiclecan
be seriouslyimpaired if:
Rbrakepads other than those recommended
are installed
Rtherecommended brakefluid is notused
Safe braking can no longer be guaranteed.
AMG high-performance and ceramic
brakes
The high-performance brake system is
installed only on the CLS 63 AMG.
The AMG brake systems are designed for
heavy loads. This may lead to noise when
braking. This will depend on:
RSpeed
RBraking force
REnvironmental conditions, such as
temperature and humidity
The wear of individualcomponentsofthe
brake system, such as the brake pads/linings
or brake discs, depends on the individual
driving style and operating conditions.
For this reason, it is impossibletostate a
mileage that will be valid under all
circumstances. An aggressive driving style
will lead to high wear. You can obtain further
information aboutthis from your authorized
Mercedes-BenzCenter.

Cleaning the paintwork
!Do not affix:
Rstickers
Rfilms
Rmagnetic plates or similar items
to painted surfaces.You could otherwise
damage the paintwork.
Scratches, corrosive deposits, areas affected
by corrosion and damage caused by
inadequate care cannot always be completely
repaired. In such cases, visitaqualified
specialist workshop.
XRemove dirt immediately, where possible,
while avoiding rubbing too hard.
XSoak insect remains with insect remover
and rinse off the treated areas afterwards.
XSoak bird droppings with water and rinse
off the treated areas afterwards.
XRemove coolant, brake fluid, tree resin,
oils, fuels and greases by rubbing gently
withacloth soaked in petroleum ether or
lighter fluid.
XUse tar remover to remove tar stains.
XUse silicone remover to remove wax.
If water no longer forms "beads" on the paint
surface, use the paint care products
recommended and approved by Mercedes-
Benz.This is the case approximately every
three to five months, depending on the
climate conditionsand the care product used.
If dirt has penetrated the paint surface or if
the paint has become dull, the paint cleaner
recommended and approved by Mercedes-
Benz should be used.
Do not use these care products in the sun or
on the hood while the hood is hot.
XUseasuitable touch-up stick,e.g. MB
Touch-Up Stick, to repair slight damage to
the paintwork quickly and provisionally.
Mattefinish care
!Never polish the vehicle or the light alloy
wheels. Polishing causes the finish to
shine.
!The following may cause the paint to
become shiny and thus reduce the matte
effect:
RVigorous rubbing with unsuitable
materials.
RFrequent use of car washes.
RWashing the vehicle in direct sunlight.
!Never use paint cleaner, buffing or
polishing products, or gloss preserver, e.g.
wax. These products are only suitable for
high-gloss surfaces. Their use on vehicles
with matte finish leads to considerable
surface damage (shiny, spotted areas).
Always have paintwork repairs performed
ataqualified specialist workshop, e.g. an
authorized Mercedes-BenzCenter.
!Do not use wash programs withahot wax
treatment under any circumstances.
Observe these notes if your vehicle has a
clear mattefinish. This will help you to avoid
damage to the paintwork due to incorrect
treatment.
These notes also apply to light alloy wheels
withaclear mattefinish.
iThe vehicle should preferably be washed
by hand usingasoft sponge, car shampoo
and plenty of water.
iUse only insectremover and car shampoo
from the range of recommended and
approved Mercedes-Benz care products.

The engine oils are matched to the
performance of Mercedes-Benz engines and
service intervals. You should therefore only
use engine oils and oil filters that are
approved for vehicles with maintenance
systems.
Foralist of approved engine oils and oil filters,
consult an authorized Mercedes-Benz
Center. Or visit the website
http://bevo.mercedes-benz.com.
The table shows which engine oils have been
approved for your vehicle.

Use only SAE 0W-40orSAE 5W-40 engine oils
for AMG vehicles.
iMB approval is indicated on the oil
containers.
Fillingcapacities
The following values refer to an oil change
including the oil filter.
ModelCapacity

All models (AMG

cooler: 9.0 US qt
(8.5 l)
Additives
!Do not use any additives in the engine oil.
This coulddamage the engine.
Engine oil viscosity
Viscosity describes the flow characteristics
ofafluid. If an engine oil hasahigh viscosity,
this means that it is thick;alow viscosity
means that it is thin.
Select an engine oil with an SAE classification
(viscosity) suitable for the prevailing outside
temperatures. The table showsyou which
SAE classifications are to be used. The low-
temperature characteristics of engine oils
can deteriorate significantly, e.g. asaresult
of aging, soot and fuel deposits. It is therefore
strongly recommendedthat you carry out
regular oil changes using an approved engine
oil with the appropriate SAE classification.
Brake fluid
GWARNING
The brake fluidconstantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
fluidistoo low,vaporpocketsmay form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There isarisk of an accident.
You should have the brake fluid renewed at
the specified intervals.
Comply with the important safety notes for
service products when handling brake fluid
(Ypage 373).
The brake fluid change intervals can be found
in the Maintenance Booklet.
