R
efficien tuse 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.
The vehicle will use more fuel than usual in
the following situations:
R at very low outside temperatures
R in urban traffic
R on short journeys
R in mountainous terrain
R when towing a trailer
i Only for certain countries: you can find
the current consumption and emission val-
ues of your vehicle in the COC documents
(EU CERTIFICATE OF CONFORMITY). These
documents are delivered with your vehicle.
The consumption figures were in each case
based on the currently applicable version:
R for vehicles that comply with standards
up to and including the EURO 4standard,
in accordance with EU Directive
80/1268/EEC
R for vehicles tha tcomply with or exceed
the EURO 5standard, in accordance with
Regulation (EC )No. 715/2007
Deviations from these values may occur
under normal operating conditions. Engine oil
General notes The quality of the engine oil is decisive for the
function and service life of an engine. After
extensive tests, Mercedes-Benz approves
engine oils that correspond to the current
technical standard.
Therefore, only Mercedes-Benz approved
engine oils may be used in Mercedes-Benz
engines. Further information on tested and approved
engine oils can be obtained from any
Mercedes-Benz Service Centre. Mercedes-
Benz recommends that you have the oil
change carried out at a qualified specialist
workshop. Mercedes-Benz approval is indica-
ted on the oil container by the inscription "MB
Approval" and the corresponding designa-
tion, e.g. MB Approval 229.51.
You can call up an overview of approved
engine oils on the Internet at:
http://bevo.mercedes-benz.com by enter-
ing the designation, e.g. 229.5.
The table shows which engine oils have been
approved for your vehicle. Petrol engines MB Approval

If the engine oils listed in the table are not
available, you may add the following engine
oils until the next oil change:
R vehicles with a petrol engine: MB
Approval 229.1 229.3 or ACEA A3
R diesel engines: MB Approval 229.1,
229.3, 229.5 or ACEA C3

quantity must not be greater than 1.0 l. Service products and capacities

Additives
!
Do no tuse any additives with the engine
oil. This could damage the engine.
Engine oil viscosity Viscosity describes the flow characteristics
of a fluid. If an engine oil has a high viscosity
rating, it flows slowly; the lower the viscosity,
the faster it flows. Engine oil selection is based on the respective
outside temperatures and in accordance with
the SAE classification (viscosity). The table
shows you which SAE classifications are to be
used. The low-temperature properties of
engine oils can be significantly impaired dur-
ing operation due to, for example, ageing or
soot and fuel accretion. It is therefore
strongly recommended to observe regularo il
changes using an approved engine oil with the
appropriate SA Eclassification. Brake fluid
G
WARNING
Over a period of time, the brake fluid absorbs
moisture fro mthe air; This lowers its boiling
point.
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 impairs braking effi-
ciency.
You should have the brake fluid renewed at
regular intervals. The brake fluid change inter-
vals can be found in the Service Booklet.
Only use brake fluid approved by Mercedes-
Benz according to MB Approval 331.0.
Information about approved brake fluid can
be obtained at any qualified specialist work-
shop or on the Internet at
http://bevo.mercedes-benz.com.
i Have the brake fluid renewed regularly at
a qualified specialist workshop. Coolant
Important safety notes G
WARNING
Antifreeze is highly flammable. Fire, naked
flames and smoking are prohibited when han-
dling antifreeze. 376
Service products and capacitiesTechnical data

If antifreeze comes into contact with hot
engine parts, it may ignite and you could burn
yourself. Do not spill any antifreeze on hot
engine parts.
! Only add coolant that has been premixed
with the desired antifreeze protection. You
could otherwise damage the engine.
Further information on coolants can be
found in the Mercedes-Benz Specifications
for Service Products, MB Specifications for
Service Products 310.1, e.g. on the Inter-
net at http://bevo.mercedes-benz.com.
Or contact a qualified specialist workshop.
! Always use a suitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosion and
overheating.
! The engine cooling system is filled with
coolant, which must be renewed after
15 years or after 250,000 kilometres at the
latest.
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
If antifreeze/corrosion inhibitor is present in
the correct concentration, the boiling point of
the coolant during operation will be around
130 †.
The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should:
R be at least 50 %. This will protect the engine
cooling system against freezing down to
around -37 †.
R not exceed 55 % (antifreeze protection
down to -45 †). Hea twill otherwise not be
dissipated as effectively.
If the vehicle has lost coolant, top it up with
equal amounts of water and antifreeze/cor- rosio
ninhibitor. Mercedes-Benz recom-
mends an antifreeze/corrosion inhibito rcon-
centrate in accordance with MB Specifica-
tions for Service Products 310.1.
The coolant is checked at every maintenance
interval at a qualified specialist workshop.
i When the vehicle is first delivered, it is fil-
led with a coolant mixture that ensures
adequate antifreeze and corrosion protec-
tion. Windscreen and headlam
pcleaning
system
Important safety notes G
WARNING
Windscreen washer fluid/antifreeze is highly
flammable. Avoid spilling windscreen washer
fluid/antifreeze on hot engine components as
it can ignite and burn. Severe burns could be
the result.
! Only use washer fluid that is suitable for
plastic lamp lenses, e.g. MB SummerFit or
MB WinterFit. Unsuitable washer fluid
could damage the plastic lense softhe
headlamps.
! Do not use distilled or de-ionised water in
the washer fluid reservoir. Otherwise, the
level sensor may be damaged.
! Only the washer fluids SummerFit and
WinterFit can be mixed. Otherwise, the
spraying nozzles could become blocked.
At temperatures above freezing:
X Fill the washer fluid reservoir with a mixture
of water and washer fluid, e.g. MB Sum-
merFit.
Mix 1 part MB SummerFit to 100 parts water. Service products and capacities

24 GHz radar sensor system (country overview)
The 24 GHz rada rsensor system requires separate approval for each country. If you are driving
in a country in which the radar sensor system is not approved, you must deactivate the system
using the on-board computer (Y page 245).
The current country overview can be obtained from a Mercedes-Benz Service Centre or on
the Internet at: http://www.mercedes-benz.de/betriebsanleitung.
Vehicles with anavigation system: the radar sensor system is deactivated automatically
near radio telescope facilities. Adisplay message appears in the multifunction display to tell
you that the radar sensor system is being switched off (Y page 263).
The currently active systems are automatically deactivated:
R DISTRONIC PLUS (Y page 188)
R Blind Spot Assist (Y page 210)
R Active Blind Spot Assist (Y page 214)
R BAS PLUS (Y page 65)
R PRE-SAFE ®
Brake (Y page 69)
If deactivation does not occur automatically, you must deactivate the radar sensor system
using the on-board computer (Y page 245).
Vehicles withou tnavigation and vehicles for Australia: you must deactivate the radar
sensor system using the on-board computer whe nyou are near a radio telescope facility
(Y page 245). 382
