Notes on service products and capaci-
ties
Service products are:
R fuels (e.g. petrol, diesel)
R lubricants
(e.g. engine oil, transmission oil)
R coolant
R brake fluid
R windscreen washer fluid
Mercedes-Benz recommends that you only
use those products which have been tested
and specially approved by Mercedes-Benz for
your vehicle and are listed in the Mercedes-
Benz Owner's Manual in the relevant chapter
since:
R parts and service products are matched
R damage caused by the use of non-approved
service products is not covered by the war-
ranty
You can recognise service products approved
by Mercedes-Benz by the following inscrip-
tion on the containers:
R MB-Freigabe (e.g. MB-Freigabe 229.51)
R MB Approval (e.g. MB Approval 229.51) Other designations or recommendations that
relate

to a level of quality or a specification in
accordance with an MB Approval have not
necessarily been approved by Mercedes-
Benz.
You can obtain further information from any
Mercedes-Benz Service Centre. G
Risk of injury
When handling, storing and disposing of
any service products, please observe the
relevant regulations, as you could other-
wise endanger yourself and others.
Keep

service products away from children.
To protect your health, do not allow service
products to come into contact with your
eyes or open wounds. See a doctor imme-
diately if any service product is swallowed. H
Environmental note
Dispose of service products in an environ-
mentally-responsible manner. Fuels
G
Risk of explosion
Fuel is highly flammable. Fire, naked flames
and
smoking are therefore prohibited when
handling fuels.
Before refuelling, turn off the engine and
the auxiliary heating*. G
Risk of injury
Do not allow fuel to come into contact with
skin or clothing.
Allowing fuels to come into direct contact
with your skin or inhaling fuel vapours is
damaging to your health.

injection system. Damage resulting from
adding
the wrong fuel is not covered by the
warranty.
More information about refuelling and fuels
can be found in the "Operation" section. Introduction to fuel consumption
The vehicle will use more fuel than usual in
the following situations: R
at very low temperatures
R in urban traffic
R on short trips
R in mountainous terrain
! Do not use any special additives, as they
can cause malfunctions and engine dam-
age.
Damage resulting from the use of such
additives is not covered by the Mercedes-
Benz warranty. H
Environmental note
CO 2 (carbon dioxide) is the gas which sci-
entists
believe to be principally responsible
for global warming (the greenhouse effect).
Your vehicle's CO 2 emissions are directly
related to fuel consumption and therefore
depend on: R
efficient use of the fuel by the engine
R driving style
R other

non-technical factors, such as envi-
ronmental influences or road conditions
You can minimise your vehicle's CO 2 emis-
sions by driving carefully and having it serv-
iced regularly. Technical data

316 Coolant
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
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 cooling
system against freezing down to around –
37 °C.
R not exceed 55% concentration (antifreeze
protection down to –45 °C), otherwise heat
will not be effectively dissipated.
If the vehicle has lost coolant, top it up with
equal amounts of water and antifreeze/cor-
rosion inhibitor. Mercedes-Benz recom-
mends using an antifreeze/corrosion inhibi-
tor 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

Brake 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 would
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 4.5 litres; on vehicles with the head-
lamp cleaning system* it holds 7 litres.
The headlamp cleaning system*
and the
windscreen washer system are both supplied
from the washer fluid reservoir.
