The antifreeze concentrate/corrosion inhibitor
concentration 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 concentrate in accordance
with MB Specifications 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 with every mainte-
nance interval at a qualified specialist work-
shop.

Windshield washer system
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.
!Only use washer fluid that is suitable for
plastic lamp lenses, e.g. MB SummerFit or MB WinterFit. Unsuitable washer fluid could dam-
age the plastic lenses of the headlamps.
!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 361).
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, as well as SAE standard J639,
must be adhered to.
Always have work on the climate control system
carried out at a qualified specialist workshop.

!Use a drawbar noseweight as close as pos-
sible to the maximum permissible nose-
weight. Do not use a noseweight of less than
50 kg, otherwise the trailer may come loose.
Note that the payload and the rear axle load
are reduced by the actual payload.
The drawbar load reduces the permissible over-
all load and rear axle load.
The drawbar load acts from above onto the ball
head on the trailer tow hitch.
The drawbar noseweight is not included in the
trailer load.

The actual noseweight may not be higher than
the value which is given. The value can be found
on the trailer tow hitch or trailer identification
plates. The lowest weight applies.
The maximum permissible trailer drawbar nose-
weight is the maximum weight with which the
trailer drawbar can be loaded. The permissible
trailer drawbar noseweight is the limit for
Mercedes-Benz-approved trailer couplings.
