Notes on service products and capaci-
ties
Service products are:
R fuels
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
alevel of quality or aspecification in
accordanc ewith 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

Al ist of engine oils tested and approved in accordanc ewith the Mercedes-Benz Specification sfor Service Products is available from any
Mercedes-Benz Service Centre. Oils approved by Mercedes-Benz are indicated by the MB Sheet Number on the oil container. The table shows

In the event that the

R grade (MB sheet number)
R SAE classification (viscosity) of the oil currently in your vehicle is not
available, you can use another mineral or
synthetic engine oil which has been
approved by Mercedes-Benz.
Mixing oils reduces the benefits of high-
grade engine oil. !
Do not use lubricant additives, since they
can lead to increased wear and damage to
the mechanical assemblies. The use of
lubricant additives will result in arestriction
of your warranty.

Coolant
The coolant is amixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
R anti-corrosion protection
R antifreez eprotection
R raising the boiling point
i When the vehicle is first delivered, it is
topped up with acoolant that will ensure
adequate antifreez eand corrosion protec-
tion.
! Only top up with coolant that has been
premixed with the desired antifreez epro-
tection. 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 asuitable 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 correctc oncentration, 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 freezingd own 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 afilling
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 Technical data
