Engine number
The engine number is stamped on the crank-
case. More information can be obtained from
any Mercedes-Benz Service Centre. Service products and capacities
Service products include the following:
R fuels (e.g. petrol, diesel)
R exhaust gas aftertreatment additive
(AdBlue ®
)
R lubricants (e.g. engine oil, transmission oil)
R coolant
R brake fluid
R windscreen washer concentrate
Mercedes-Benz recommends that you only
use products which have been tested and
specially approved by Mercedes-Benz for
your vehicle and which are listed in this
Mercedes-Benz Owner's Manual in the rele-
vant 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
implied warranty.
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 Sheet number (such
as MB 229.5) 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 otherwise 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 immediately if
any service product is swallowed.
H
Environmental note
Dispose of service products in an environ-
mentally-responsible manner. Fuel
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.

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
implied warranty.

Low outside temperatures
AdBlue
®
freezes at a temperature of approx-
imately –11 †. The vehicle is equipped with
an AdBlue ®
preheating system at the factory.
Winter operation is therefore also guaranteed
at temperatures below –11 †.
Special additives !
Only use AdBlue ®
compliant with
ISO 22241. Do not add any special addi-
tives to AdBlue ®
and do not dilute it with
water. Doing so may destroy the BlueTEC
exhaust gas aftertreatment system.
Damage resulting from the use of such
additives or from water is not covered by
the Mercedes-Benz implied warranty.
Purity The purity of AdBlue
®
is particularly important
for avoiding malfunctions in the exhaust gas
aftertreatment system.
If AdBlue ®
is pumped out of the AdBlue ®
tank,
e.g. during repair work, it must not be
returned to the tank as the purity of the fluid
can no longer be guaranteed.
! Impurities in AdBlue ®
(e.g. due to other
service products, cleaning agents or dust) lead to increased emission values, system
malfunctions, catalytic converter damage
or damage to the BlueTEC system. Vehicle model Total capacity of
the AdBlue ®
tank GL 350 BlueTEC 31.7 l
Engine oil
Only Mercedes-Benz approved engine oils
may be used in Mercedes-Benz engines.
A list of the engine oils tested and approved
in accordance with the Mercedes-Benz Spec-
ifications for Service Products can be called
up by visiting http://bevo.daimler.com and
entering the MB Sheet number. Further infor-
mation on tested and approved engine oils
can be obtained 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
under the "MB approval" notice. The table
shows which MB Sheet number applies to
which engine: GL 450 4MATIC

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. You must
then have an oil change carried out at the
earliest possible opportunity.
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 oil viscosity
Viscosity describes the flow characteristics
of a fluid. If an engine oil has a high viscosity,
this means it is thick; a low viscosity means
that it is thin.
Select the SAE classification (viscosity) of the
engine oil according to the outside tempera-
ture. The following table shows you the vis-
cosity classes to be used depending on the
average air temperature. Capacities
The following values refer to an oil change
including the oil filter. Vehicle model Capacity including
