Brake fluid level
!If you notice that the brake fluid level in the
brake fluid reservoir has fallen to the MIN
mark or less, check the brake system imme-
diately for leaks. Also check the thickness of
the brake linings. Visit a qualified specialist
workshop immediately.
Do not add brake fluid. This does not correct
the error.
Only check the brake fluid level when the vehicle
is on a level surface.
If the brake fluid level is between MIN mark :
and MAX mark ;on the brake fluid reservoir, it
is correct.

distances
240Maintenance
Maintenance and care
Cleaning the steering wheel and gear or
selector lever
XThoroughly wipe with a damp cloth or use
leather care agents that have been recom-
mended and approved by Mercedes-Benz.
Cleaning genuine wood and trim strips
!Do not use solvent-based cleaning agents
such as tar remover, wheel cleaners, polishes
or waxes. There is otherwise a risk of damag- ing the surface.
!Do not use chrome polish for trim strips. The
trim strips have a chrome look but are mostly
made of anodized aluminum and can lose
their shine if chrome polish is used. Use a
damp, lint-free cloth instead when cleaning
the trim strips.
If the chrome-plated trim strips are very dirty,
you can use a chrome polish. If you are unsure
as to whether the trim strips are chrome-
plated or not, consult an authorized
Mercedes-Benz Center.
XWipe the wooden trim and trim strips with a
damp, lint-free cloth, e.g. a microfiber cloth.
XHeavy soiling: use car care and cleaning
products recommended and approved by
Mercedes-Benz.
Cleaning the seat covers
General notes
!Do not use microfiber cloths to clean genu-
ine 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 cov-
ers 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 covers
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 qualified
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%
detergen
t (e.g. dish washing liquid). Rub
carefully 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 sec-
tions 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.

Climate control system refrigerant
Important safety notes
The climate control system of your vehicle is fil-
led with refrigerant R‑ 134a.
The instruction label regarding the refrigerant
type used can be found on the radiator cross
member.
!Only the refrigerant R ‑134a and the PAG oil
approved by Mercedes-Benz may be used.
The approved PAG oil may not be mixed with
any other PAG oil that is not approved for
R-134a refrigerant. Otherwise, the climate
control system may be damaged.
Service work, such as topping up refrigerant or
replacing components, may only be carried out
by a qualified specialist workshop. All applicable
regulations must be adhered to, SAE standard
J639 included.
Always have work on the climate control system
carried out at a qualified specialist workshop.

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 impor-
tant safety notes on service products
(
Ypage 289).
The brake fluid change intervals can be found in
the Maintenance Booklet.
Only use brake fluid approved by Mercedes-
Benz according to MB-Freigabe or MB Approval
331.0.
Information about approved brake fluid can be
obtained at any qualified specialist workshop or on the Internet at
http://bevo.mercedes-benz.com.
iHave the brake fluid regularly replaced at a
qualified specialist workshop and the replace-
ment 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 Ser-
vice Products, MB BeVo 310.1, e.g. on the
Internet 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.
iHave the coolant regularly replaced at a
qualified specialist workshop and the replace-
ment confirmed in the Maintenance Booklet.
Comply with the important safety precautions
for service products when handling coolant
(
Ypage 289).
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the fol-
lowin g t
asks:
Rcorrosion protection
Rantifreeze protection
Rraising the boiling point
If the coolant has antifreeze protection down to -35 ‡(-37 †), the boiling point of the coolant in
the pressurized system is approximately 266 ‡ (130 †). The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should:
Rbe at least 50%. This will protect the engine
cooling system against freezing down to
approximately -35 ‡ (-37 †).
Rnot exceed 55% (antifreeze protection down
to -49
‡[-45 †]) .Otherwise ,hea twill no tbe
dissipated as effectively.

Yo ur vehicle has a ran ge of alum
inum compo-
nents. Aluminum components in the engine
make itnecessary to use antifreeze/corrosion
inh ibit or that has been specific allyformulated to
protect the aluminum parts. Failure to use such
anticorrosion/antifreeze coolant willresult in a
significantly shortened service life.
The coolant must beused throughout the year in
order to maintain the necessary corrosion pro-
tection and to provide protection from over-
heating. Inthe Maintenance Booklet, you can
find information on the intervals for renewal.
The renewal interval is determined bythe cool-
ant type and the engine co oling system design.
The renewal interval in the Maintenance Booklet
is only valid if the coolant is renewed or added to
wit h Mercedes-Benz approved products. There-
fore, only use MB 326.0 antifreeze/corrosion
inh ibit or or another Mercedes-Benz approved
product of the same specification.
In formation on other products with the same
specifications that are approved byMercedes-
Benz can beobtained at an authorized
Mercedes-Benz Center or on the Internet at
ht tp://bevo.mercedes-benz.com .
If the coolant level is too low, MB 325.0 anti-
freeze/corrosion inh ibitor should beadded.
Have the engine co oling system c
hecked for
possible leaks.
