Cleaning the seat covers
General notes
!Do not use microfiber cloths to clean gen-
uine leather, artificial leather or DINAMICA
covers. If used often, these can damage the
cover.
iNote that regular care is essential to
ensure that the appearance and comfort of
the covers is retained over time.
Genuine leather seat covers
!To retain the natural appearance of the
leather, observe the following cleaning
instructions:
RClean genuine leather covers carefully
with a damp cloth and then wipe the cov-
ers down with a dry cloth.
RMake sure that the leather does not
become soaked. It may otherwise
become rough and cracked.
ROnly use leather care agents that have
been tested and approved by Mercedes-
Benz. You can obtain these from a quali-
fied specialist workshop.
Leather is a natural product.
It exhibits natural surface characteristics, for
example:
Rdifferences in the texture
Rmarks caused by growth and injury
Rslight nuances of color
These are characteristics of leather and not
material defects.
Seat covers of other materials
!Observe the following when cleaning:
Rclean artificial leather covers with a cloth
moistened with a solution containing 1%
detergent (e.g. dish washing liquid).
Rclean cloth covers with a microfiber cloth
moistened with a solution containing 1%
detergent (e.g. dish washing liquid). Ru b
ca
refully and always wipe entire seat sec-
tions to avoid leaving visible lines. Leave
the seat to dry afterwards. Cleaning
results depend on the type of dirt and
how long it has been there.
Rclean DINAMICA covers with a damp
cloth. Make sure that you wipe entire
seat sections to avoid leaving visible
lines.
Cleaning the seat belts
GWARNING
Seat belts can become severely weakened if
bleached or dyed. This could cause the seat
belts to tear or fail, for instance, in the event of an accident. This poses an increased risk of
injury or fatal injury.
Never bleach or dye the seat belts.
!Do not clean the seat belts using chemical
cleaning agents. Do not dry the seat belts
by heating at temperatures above 176 ‡
(80 †) or in direct sunlight.
XUse clean, lukewarm water and soap solu-
tion.

ded additives can be obtained from any
authorized Mercedes-Benz Center.
Mercedes-Benz recommends that you use
branded fuels that have additives.
The quality of the fuel available in some coun-
tries may not be sufficient. Residue could
build up in the injection system as a result. In
such cases, and in consultation with an
authorized Mercedes-Benz Center, the gaso-
line may be mixed with the cleaning additive
recommended by Mercedes-Benz. You must
observe the notes and mixing ratios specified
on the container.
Engine oil
General notes
!Never use engine oil or an oil filter of a
specification other than is necessary to ful-
fill the prescribed service intervals. Do not
change the engine oil or oil filter in order to
achieve longer replacement intervals than
those prescribed. You could otherwise
cause engine damage or damage to the
exhaust gas aftertreatment.
Follow the instructions in the service inter-
val display regarding the oil change. Other-
wise, you may damage the engine and the
exhaust gas aftertreatment.
When handling engine oil, observe the impor-
tant safety notes on service products
(
Ypage 347).
The engine oils are matched to the perform-
ance 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.
For a list of approved engine oils and oil filters,
consult an authorized Mercedes-Benz Cen-
ter. Or visit the website
http://bevo.mercedes-benz.com.
The table shows which engine oils have been
approved for your vehicle.
ModelMB-Freigabe or MB-
Approval
All models229.5
Mercedes ‑AMG vehicles: use only
SAE 0W-40 or SAE 5W-40 engine oils.
iMB approval is indicated on the oil con-
tainers.
Filling capacities
The following values refer to an oil change
including the oil filter.
ModelCapacity

SLK 3506.9 US qt (6.5l)
Mercedes‑AMG
SLK 5510.0 US qt (9.5 l)
Additives
!Do not use any additives in the engine oil.
This could damage the engine.
Engine oil viscosity
Viscosity describes the flow characteristics
of a fluid. If an engine oil has a high viscosity,
this means that it is thick; a low viscosity
means that it is thin.
Select an engine oil with an SAE classification
(viscosity) suitable for the prevailing outside

temperatures. The table shows you which
SAE classifications are to be used. The low-
temperature characteristics of engine oils
can deteriorate significantly, e.g. as a result
of aging, soot and fuel deposits. It is therefore
strongly recommended that you carry out reg-
ular oil changes using an approved engine oil
with the appropriate SAE classification.
Brake fluid
GWARNING
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
fluid is too low, vapor pockets may form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There is a risk of an accident.
You should have the brake fluid renewed at
the specified intervals.
When handling brake fluid, observe the
important safety notes on service products
(
Ypage 347).
The brake fluid change intervals can be found
in the Maintenance Booklet.
Only use brake fluid approved by Mercedes-
Benz in accordance with MB-Freigabe or MB-
Approval 331.0.
Information about approved brake fluid can
be obtained at any qualified specialist work-
shop or on the Internet at
http://bevo.mercedes-benz.co m.
iHave the brake fluid regularly replaced at
a qualified specialist workshop and the
replacement confirmed in the Maintenance
Booklet.
Coolant
Important safety notes
GWARNING
If antifreeze comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Let the engine cool down before you add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly clean the
antifreeze from components before starting
the engine.
!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 BeVo 310.1, e.g.
on the Internet at
http://bevo.mercedes-benz.com. Or con-
tact 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.
iHave the coolant regularly replaced at a
qualified specialist workshop and the
replacement confirmed in the Maintenance
Booklet.
Comply with the important safety precautions
for service products when handling coolant
(
Ypage 347).
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
Rcorrosion protection
Rantifreeze protection
Rraising the boiling point
If the coolant has antifreeze protection down
to -35 ‡(-37 †), the boiling point of the cool-
