Risk of accident
Only have a trailer coupling retrofitted at a
qualified specialist workshop which has the
necessary specialist knowledge and tools
to carry out the work required. Mercedes-
Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety
or on safety-related systems must be car-
ried out at a qualified specialist workshop.
! If you have a trailer tow hitch retrofitted,
changes to the cooling system may be nec-
essary, depending on the vehicle type.
If you have a trailer tow hitch retrofitted,
observe the anchorage points on the chas-
sis frame. Anchorage points for the trailer coupling

Notes on service products and capaci-
ties
Service products are:
R fuels (e.g. petrol, diesel)
R lubricants (e.g. engine oil, transmission oil,
grease)
R coolant
R brake 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 Specifications for Service Products
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 obtain further information from any
Mercedes-Benz Service Centre. G
Risk of accident
When handling, storing and disposing of
any service products, please observe the
relevant regulations. Failure to do so could endanger other persons and the environ-
ment.
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. Tank capacity Total capacity Approximately 96 l

Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel
vehicles with a petrol engine. Never mix
diesel with petrol. Even small amounts of
the wrong fuel result in damage to the
injection system. Damage resulting from
adding the wrong fuel is not covered by the
warranty.

277Notes on 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 when towing a trailer
R in mountainous terrain
The consumption figures have been deter-
mined according to EU Directive
RL 80 /1268 /EEC.
i Only for certain countries: the respective
current consumption and emission values of your vehicle can be found in the COC
papers (EC CERTIFICATE OF CONFORM-
ITY). These documents are supplied when
the vehicle is delivered.
! 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 2emissions 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 2emis-
sions by driving carefully and having it serv-
iced regularly. Technical data

279Engine oil
A list of engine oils tested and approved in accordance with the Mercedes-Benz Specifications for Service Products is available from any
Mercedes-Benz Service Centre. Engine oils which have been approved by Mercedes-Benz have the MB Sheet number indicated on the oil
container. The table shows which MB Sheet Number applies to which engine: G 500 G 320 CDI G 55 AMG

In the event that the:
R engine oil brand
R grade (MB Sheet number)
R SAE classification (viscosity)
is not available, you can use another min-
eral 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 as they can
lead to increased wear and damage to
mechanical assemblies. The use of lubri- cant additives will result in a restriction of
your warranty.
! Engine oils for vehicles without a diesel
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.

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 antifreeze pro-
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 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 vehicles.
! The cooling system contains a filling
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, and
observe the recommended mixing ratios. Technical data
