injection system. Damage resulting from
adding the wrong fuel is not covered by the
warranty.
Further information on refuelling and on fuels
(Y page 144).
Notes 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 in accordance with 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 scien-
tists 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. 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.co m and
en tering 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: GLK 280 4MATIC

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 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.
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

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. Otherwise, you could damage the
engine.
Further information on coolants and on fill-
ing can be found in the Mercedes-Benz
Specifications for Service Products, sheet Service products and capacities

310.1, or at any Mercedes-Benz Service
Centre.
! 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 an antifreeze/corrosion inhibitor
which has been approved for Mercedes-Benz.
!
The cooling system contains a supply
which must be renewed after 15 years, or
after 250, 000 km at the latest.
The warranty is only valid if you top up with
an antifreeze/corrosion inhibitor which
has been approved by Mercedes-Benz and
the recommended mixture ratio is
observed.

system capacities.

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. 248 Service products and capacitiesTechnical data

Tyres and wheels
Points to remember
! For safety reasons, Mercedes-Benz rec-
ommends that you only use tyres which
have been approved specifically for your
vehicle by Mercedes-Benz. These tyres are
specially adapted for use with the control systems, such as ABS or ESP
®
, and are
marked as follows:
R MO = Mercedes-Benz Original
If you use other tyres, Mercedes-Benz can-
not accept any responsibility for damage
which may occur. Information about tyres
can be obtained from any Mercedes-Benz
Service Centre.
! If you fit tyres other than those tested and
recommended by Mercedes-Benz, charac-
teristics such as handling, noise levels and
fuel consumption, etc. may be adversely
affected. In addition, when driving with a
load, tyre dimensional variations could
cause the tyres to come into contact with
the bodywork and axle components. This
could result in damage to the tyres or the
vehicle.
i Further information about tyres and
wheels can be obtained from any
Mercedes-Benz Service Centre.
You will find a table of tyre pressures on the
inside of your vehicle's fuel filler flap. You
will find further information about tyre pres-
sures in the "Operation" section
(Y page 152).

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 purpose. In particular,
work relevant to safety or on safety-related
systems must be carried 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
