Important safety notes G
WARNING
Antifreeze is highly flammable. Fire, naked
flames and smoking are prohibited whe nhan-
dling antifreeze.
If antifreeze comes into contact with hot
engine parts, it may ignite and you could burn
yourself. Do no tspill any antifreeze on hot
engine parts.
! 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 Specifications for
Service Products 310.1, e.g. on the Inter-
net 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.
! The engine cooling system is filled with
coolant, which must be renewed after
15 years or after 250,000 kilometres at the
latest. The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
R
anti-corrosion protection
R antifreeze protection
R raising the boiling point
If antifreeze/corrosion inhibito ris present in
the correct concentration, the boiling point of
the coolant during operation will be around
130 †.
The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should:
R be at least 50%. This will protect the engine
cooling system against freezing down to
around -37 †.
R not exceed 55% (antifreeze protection
down to -45 †). Otherwise, heat will not be
dissipated as effectively.
If the vehicle has lost coolant, top it up with
equal amounts of water and antifreeze/cor-
rosion inhibitor. Mercedes-Benz recom-
mends an antifreeze/corrosion inhibitor con-
centrate in accordance with MB Specifica-
tions for Service Products 310.1.
i When the vehicle is first delivered, it is fil-
led with a coolant mixture that ensures
adequate antifreeze and corrosion protec-
tion. Washer fluid
G
WARNING
Windscreen washer fluid/antifreeze is highly
flammable.A void spilling windscreen washer
fluid/antifreeze on hot engine components as
it can ignite and burn. Severe burns could be
the result.
! Only use washer fluid that is suitable for
plastic lamp lenses, e.g. MB SummerFit or
MB WinterFit. Unsuitable washer fluid
could damage the plastic lenses of the
headlamps. 316

!
Do not use distilled or de-ionised water in
the washer fluid reservoir. Otherwise, the
level sensor may be damaged.
! Only the washer fluids SummerFit and
WinterFit can be mixed. Otherwise, the
spraying nozzles could become blocked.
At temperatures above freezing:
X Fill the washer fluid reservoir with a mixture
of water and washer fluid, e.g. MB Sum-
merFit.
X Mix 1 part MB SummerFit to 100 parts
water.
At temperatures below freezing:
X Fill the washer fluid reservoir with a mixture
of water and washer fluid, e.g. MB Winter-
Fit. Adapt the mixing ratio to the outside
temperatures.
X Down to Ò10 †: mix 1 part MB WinterFit
with 2parts water.
X Down to Ò20 †: mix 1 part MB WinterFit
with 1 part water.
X Down to Ò29 †: mix 2 parts MB WinterFit
with 1 part water.
i Add washe rfluid concentrate, e.g. MB
SummerFit or MB WinterFit, to the washer
fluid all year round. Vehicle data

necessary specialist knowledge and tools to
carry out the work required. Mercedes-Benz
recommends that you use aMercedes-Benz
Service Centre for this purpose. In particular,
work relevant to safety or on safety-related
systems must be carried out at a qualified

24-GHz radar sensor system (country overview)
The 24 GHz radar sensor system requires separate approval for each country. If you are driving
in a country in which the radar sensor system is not approved, you must deactivate the system
using the on-board computer (Y page 203).
The current country overview can be obtained from a Mercedes-Benz Service Centre.
Vehicles with anavigation system: the radar sensor system is deactivated automatically
near radio telescope facilities. Adisplay message appears in the multifunction display to tell
you that the radar sensor system is being switched off (Y page 222).
If Blind Spot Assist is active, it will be deactivated automatically (Y page 177).
If the deactivation does not occur automatically, you must deactivate the radar sensor system
using the on-board computer (Y page 203).
23 At a minimum gradient-climbing capability of 12% fro mastandstill.
24 The drawbarn oseweight is not included in the trailer load.
