In the unusual event that the:
R engine oil brand
R grade (MB sheet number)
R SAE classification (viscosity )
corresponding to the oil used in your engine
is not available, you can use another min-
eral or synthetic engine oil approved by
Mercedes-Benz. Mixing oils reduces the advantages of
high–grade engine oil
.
! Do not use lubricant additives, since they
lead to increased wear and damage to the
mechanical assemblies. The use of lubri-
cant additives will result in a restriction of
your warranty. !
Engine oils for vehicles without a diese l
particle filter may also be used temporarily
in vehicles with a diesel particle filter if the
engine oil listed is not available. You must
then have an oil change carried out as soon
as possible.

369Coolant
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 poin t
i When the vehicle is first delivered, it is
topped up with a coolant that will ensure
adequate antifreeze and corrosion protec -
tion.
! Only top up with coolant that has been
premixed with the desired quantity of anti -
freeze protection. You could otherwise
damage the engine.
There is more information about coolant
and topping it up on Mercedes-Benz Spec-
ifications for Service Products Sheet
310.1.
! Always use a suitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the cooling system will not be
sufficiently protected from corrosion, and
the boiling point will be too low .If antifreeze/corrosion inhibitor is present in
the correct concentration, the boiling point of
the coolant will be around 130 °C.
The antifreeze/corrosion inhibitor concentra-
tion in the cooling system should:
R
be at least 50%. This will protect the coolin g
system against freezing down to around
-37 °C.
R not exceed 55% (antifreeze protection
down to -45 °C), otherwise heat will not be
effectively dissipated .
If the vehicle is losing coolant, top it up with
equal amounts of water and antifreeze/cor-
rosion inhibitor. Mercedes-Benz recom-
mends an antifreeze/corrosion inhibitor
which has been approved for Mercedes-Benz.
! The cooling system contains a lifetime
supply which must be renewed after 15
years, or after 250, 000 km at the latest.
Have the renewal confirmed in the Service
Booklet.
The warranty is only valid if you top up with
an antifreeze/corrosion inhibitor which
has been approved by Mercedes-Benz. Technical data

371Brake fluid
Over a period of time, the brake fluid absorbs
moisture from the air; this lowers its boiling
point. G
Risk of accident
If the boiling point of the brake fluid is too
low, vapour pockets may form in the brake
system when the brakes are applied hard
(e.g. when driving downhill). This woul d
impair braking efficiency.
Have the brake fluid renewed every two
years with a brake fluid that has been
approved by Mercedes-Benz and have this
confirmed in the Service Booklet.
i There is usually a notice in the engine
compartment to remind you when the next
brake fluid change is due. Windscreen washer system
The washer fluid reservoir holds approxi-
mately 4.0 litres.
The headlamp cleaning system* and the
windscreen washer system are both supplied
from the washer fluid reservoir.
X At temperatures above freezing point:
Top up the washer fluid reservoir with a
mixture of water and windscreen washer
concentrate (Y page 210).
X At temperatures below freezing point:
Top up the washer fluid reservoir with a
mixture of water, antifreeze and wind-
screen washer concentrate (Y page 210).
Adapt the mixing ratio to the outside tem-
peratures . G
Risk of fire
Windscreen washer concentrate is highly
flammable. Fire, naked flames and smoking
are prohibited when windscreen washe r
concentrate is being handled. Technical data
