Example: adding liquid to the windshield
washer system
XTo open:pull cap:upwards by the tab and
open.
XAdd the premixed washer fluid.
XTo close: press cap :onto the filler neck
until it engages.
The washer fluid reservoir is used for both the
windshield washer system and the headlamp
cleaning system.
If the washer fluid level drops below the recom-
mended minimum of 3.7 US qt (3.5 l), a message
appears in the multifunction display prompting
you to add washer fluid (
Ypage 191).
Further information on washer fluid
(
Ypage 287).
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 stationary and on a level surface. The brake
fluid level is correct if the level is between MAX
mark :and MIN mark ;on the brake fluid
reservoir.
Maintenance
Service interval display
Service messages
You can obtain up-to-date information concern-
ing the servicing of your vehicle from a qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center or at
http://www.mbusa.com (USA only).
The ASSYST service interval display informs you
of the next service due date.
If a service due date has been exceeded, you
also hear a warning tone.
The multifunction display shows a service mes-
sage for several seconds, e.g.:
Service A In 999,999 km
Service A in .. Days
Service A Due
Service A Exceeded 999,999 km
Service A Exceeded .. Days
Maintaining the time-dependent service sched-
ule:
XBefore disconnecting the battery, note down
the service due date displayed.
or
XAfter reconnecting the battery, subtract the
battery disconnection periods from the ser-
vice date shown on the display.
The service interval display should not be con-
fused with the 4engine oil level display.
The symbol and the letter indicate which type of
service is due:
¯ Minor service A
±
Major service B
The ASSYST service interval display does not
take into account any periods of time during
which the battery is disconnected.

Maintenance and care
Z

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, heat will not be
dissipated as effectively.
Mercedes-Benz recommends an antifreeze/
corrosion inhibitor in accordance with MB Spec-
ifications for Service Products 310.1.
iWhen the vehicle is first delivered, it is filled
with a coolant mixture that ensures adequate
antifreeze and anti-corrosion protection.
iThe coolant is checked at specified intervals
at a qualified specialist workshop.
The engine cooling system is filled with coolant
at the factory which contains antifreeze/corro-
sion inhibitor that ensures protection down to
approximately -35 ‡ (-37 †).

Important safety notes
GWARNING
Windshield washer concentrate could ignite if it comes into contact with hot engine compo-
nents or the exhaust system. There is a risk of
fire and injury.
Make sure that no windshield washer con-
centrate is spilled next to the filler neck.
!Do not add distilled or de-ionized water to
the washer fluid container. Otherwise, the
level sensor may be damaged.
!Only MB SummerFit and MB WinterFit
washer fluid should be mixed together. The
spray nozzles may otherwise become
blocked.
Do not use distilled or de-ionized water. Other-
wise, the level sensor may give a false reading.
When handling washer fluid, observe the impor-
tant safety notes on service products
(
Ypage 283).
At temperatures above freezing:
XFill the washer fluid reservoir with a mixture of
water and windshield washer fluid, e.g. MB
SummerFit.
Add 1 part MB SummerFit to 100 parts water.
At temperatures below freezing:
XFill the washer fluid reservoir with a mixture of
water and washer fluid, e.g. MB WinterFit.
For the correct mixing ratio refer to the infor-
mation on the antifreeze reservoir.
iAdd windshield washer fluid, e.g. MB Sum-
merFit or MB WinterFit, to the washer fluid all
year round.
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 refilling with refrigerant or
replacing component parts, may only be carried
out by a qualified specialist workshop. All appli-
cable regulations must be adhered to, SAE
standard J639 included.
Always have work on the climate control system carried out at a qualified specialist workshop.
