Brake fluid
G
WARNING
The brake fluid continuously absorbs mois-
ture from the air. This results in the boiling
point of the brake fluid lowering. If the boiling
point of the brake fluid is too low, vapour
pockets may form when the brakes are sub-
jected to a heavy load. This would impair brak- ing efficiency. There is a risk of an accident.
Have the brake fluid renewed at the prescri-
bed intervals.
Comply with the important safety notes for ser- vice products when handling brake fluid
(Y page 381).
The brake fluid change intervals can be found in the Service 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.
i Have the brake fluid regularly replaced at a
qualified specialist workshop in accordance
with the replacement intervals and the
replacement confirmed in the Service Book-
let. Coolant
Important safety notes G
WARNING
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 top up
the antifreeze. 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 Specifications for Service
Products 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.
i Have the coolant regularly replaced at a
qualified specialist workshop and the replace-
ment confirmed in the Service Booklet.
Observe the important safety notes for service
products when handling coolant (Y page 381).
The coolant is a mixture of water and anti-
freeze/anti-corrosion additive. It is responsible
for the following:
R corrosion protection
R antifreeze protection
R raising the boiling point
If antifreeze/corrosion inhibitor is present in the
correct concentration, the boiling point of the
coolant during operation will be approximately
130 †.
The antifreeze/anti-corrosion additive concen-
tration in the engine cooling system should:
R be at least 50%. This will protect the engine
cooling system against freezing down to
approximately -37 †.
R not exceed 55% (antifreeze protection down
to -45 †). Heat will otherwise not be dissipa- ted as effectively.
Mercedes-Benz recommends an antifreeze/
anti-corrosion additive concentrate in accord-
ance with MB Specifications for Service Prod-
ucts 310.1.
i When the vehicle is first delivered, it is filled
with a coolant mixture that ensures adequate
antifreeze and corrosion protection.
i The coolant is checked at every mainte-
nance interval at a qualified specialist work-
shop. 386

Windscreen washer system
Important safety notes G
WARNING
If windscreen washer concentrate comes into contact with hot components of the engine or
the exhaust system, it can ignite. There is a
risk of fire and injury.
Make sure the windscreen washer concen-
trate does not come into contact with 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 the washer fluids SummerFit and Win-
terFit can be mixed. Otherwise, the spraying
nozzles could become blocked.
Do not use distilled or de-ionised water. Other-
wise, the level sensor may give a false reading.
When handling washer fluid, observe the impor- tant safety notes on service products
(Y page 381).
At temperatures above freezing:
X Fill the washer fluid reservoir with a mixture of
water and washer fluid, e.g. MB SummerFit.
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 WinterFit.
For the correct mixing ratio refer to the infor- mation on the antifreeze reservoir.
i Add washer fluid concentrate, e.g. MB Sum-
merFit or MB WinterFit, to the washer fluid all
year round. Vehicle data

Fording depth
! The depth of water must not exceed the
value specified in the table. Note that the
possible fording depth is less in flowing water. The table shows fording depth
:when the
vehicle is loaded and ready to drive.
Loaded and ready to drive means: a full tank, all fluids topped up and the driver is in the vehicle.
On vehicles with the AIRMATIC package or the
Off-Road Engineering package, loads up to the
maximum permissible load have no influence on fording capability.

ity
Note that the vehicle's gradient-climbing capa-
bility depends on the off-road conditions and the road surface conditions.
Vehicles with the ON&OFFROAD package:
the maximum gradient climbing ability is 100 %
when the LOW RANGE off-road gear is selected.
Vehicles without the ON&OFFROAD pack-
age: the maximum gradient climbing ability is
80 %.
Carefully depress the accelerator pedal and
make sure that the wheels do not spin when
driving on steep terrain. Vehicle data for off-road driving

i
If the load on the front axle is reduced when
pulling away on a steep uphill slope, the front
wheels have a tendency to spin. 4ETS recog-
nises this and brakes the wheels accordingly. The rear wheel torque is increased and it is
easier to pull away.
For further information about maximum gradi-
ent-climbing capability, see (Y page 180).Trailer tow hitch
Trailer loads
Trailer loads, noseweights and axle
loads !
Use a drawbar noseweight as close as pos-
sible to the maximum permissible nose-
weight. Do not use a noseweight of less than
50kg, otherwise the trailer may come loose.
Note that the payload and the rear axle load
are reduced by the actual payload.
