G
WARNING
The engine cooling system is pressurized, par-
ticularly when the engine is warm. When
opening the cap, you could be scalded by hot
coolant spraying out. There is a risk of injury.
Let the engine cool down before opening the
cap. Wear eye and hand protection when
opening the cap. Open the cap slowly half a
turn to allow pressure to escape.
Only check the coolant level and/or fill the
coolant if the vehicle is on a level surface and
the engine has cooled down. The coolant tem-
perature must be below 122 ‡ (50 †).
! Check the engine cooling and heating sys-
tem regularly for leaks.
If a large quantity of coolant is lost, have
the cause traced and rectified at a qualified
specialist workshop. G
WARNING
Coolant contains glycol and is therefore toxic.
Do not swallow the coolant. See a doctor
immediately if you swallow coolant.
Make sure that coolant does not come into
contact with skin, eyes or clothing. In case of
contact with eyes, rinse immediately with
plenty of clean water. Clean affected areas of
skin and clothing with soap and water imme-
diately. Change any affected clothing imme-
diately. G
WARNING
If antifreeze comes into contact with hot com-
ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Let the engine cool down before you add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly clean the
antifreeze from components before starting
the engine.

Important safety notes G
WARNING
Fuel is highly flammable. Improper handling
of fuel creates a risk of fire and explosion. Avoid fire, open flames, smoking and creating
sparks under all circumstances. Switch off the
engine and, if applicable, the auxiliary heating
before refueling.
G
WARNING
Fuel is poisonous and hazardous to health.
There is a risk of injury.
You must make sure that fuel does not come
into contact with your skin, eyes or clothing
and that it is not swallowed. Do not inhale fuel
vapors. Keep fuel away from children.
If you or others come into contact with fuel,
observe the following:
R Wash away fuel from skin immediately
using soap and water.
R If fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance with-
out delay.
R If fuel is swallowed, seek medical assis-
tance without delay. Do not induce vomit-
ing.
R Immediately change out of clothing which
has come into contact with fuel.
When handling, storing and disposing of fuels,
please observe the relevant regulations. Service products and capacities
321Technical data Z
R
diesel fuel with a bio-diesel content of
more than 7%
R diesel fuel with a bio-diesel content of up
to 7%, which does not fulfill the require-
ments stated under "Fuel grade"
The sulfur content of the diesel fuel may not
exceed the following values: Euro 6 diesel engine 50 ppm
Euro 5 diesel engine ≥ 50 ppm
Euro 4 diesel engine ≥ 500 ppm
Euro 3 diesel engine ≥ 2500 ppm
You will generally find information about the
fuel grade on the filling pump. If there is no
identification on the filling pump, consult a
gas station attendant.
For more information about refueling
(Y
page 148).
i You can obtain information about modifi-
cation options for operation with alterna-
tive fuels (bio-diesel fuels) from any author-
ized Mercedes-Benz Center.
Diesel at very low outside temperatures G
WARNING
If you heat fuel system components, e.g. with
a hot-air gun or open flame, these compo-
nents could be damaged. This can cause fuel
to escape and ignite. Depending on the type
of damage, fuel may also not escape until the
engine is running. There is a risk of fire and
explosion.
Never heat fuel system components. Contact
a qualified specialist workshop to rectify the
malfunction.
Refill only with commercially available
ULTRA-LOW SULFUR DIESEL (ULSD, maxi-
mum sulfur content 15 ppm), which fulfills the
ASTM D975 standard.
The flow properties of diesel may be inade-
quate at low outside temperatures due to
paraffin separation. i
Malfunctions resulting from paraffin sep-
aration can only be rectified by heating the
entire fuel system. Park the vehicle in a
heated garage, for example.
To prevent operating problems, diesel with
better flow qualities is available during the
winter months. You can obtain information at
the gas station or from your fuel supplier.
Your vehicle is equipped with a fuel preheat-
ing system. This improves the flow properties
of the diesel by approximately 46 ‡ (8 †).
ULTRA-LOW SULFUR DIESEL can be used
without risk of malfunction down to an out-
side temperature of approximately 14 ‡
(00F810 †).
Fuel additives
! Do not add gasoline or kerosene to diesel
fuel to improve its flow characteristics.
Gasoline or kerosene impairs the lubricat-
ing properties of the diesel fuel. This can
result in damage to the fuel injection sys-
tem, for example.
Information on fuel consumption 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, road conditions or
traffic flow
You can minimize your vehicle's CO 2emis-
sions by driving carefully and having it serv-
iced regularly.
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- Service products and capacities
323Technical data Z
ITY). These documents are supplied when
the vehicle is delivered.
Consumption figures were found in the cur-
rently valid respective version:
R for vehicles from the Euro 5 standard
according to regulation (EC) no.
715/2007
R for vehicles from the Euro 6 standard
according to regulation (EC) no.
595/2009
Fuel consumption depends on:
R the vehicle version
R the style of driving
R the operating conditions
R the type or quality of the fuel used
The vehicle will use more fuel than usual in
the following situations:
R at very low outside temperatures
R in city traffic
R during short journeys
R on mountainous terrain
R when towing a trailer
To keep fuel consumption low, observe the
advice in the "Protection of the environment"
section (Y page 22).
The following components of the different
vehicle versions influence fuel consumption:
R tire sizes, tire tread, tire pressure, tire con-
dition
R body
R transmission ratios for the drive assem-
blies
R additional equipment (e.g. air-conditioning
system, auxiliary heating system).
For these reasons, the actual consumption
figures for your vehicle may deviate from the
consumption figures determined according
to EU Directive 80/1268/EEC.
Data concerning fuel consumption are
recorded in the on-board computer; use the
steering wheel buttons to call up the Trip
computer menu (Ypage 197). Diesel Exhaust Fluid (DEF) General notes
!
Only use DEF in accordance with
ISO 22241. The exhaust gas aftertreatment
system may otherwise be damaged.
Observe the MB Specifications for Service
Products, Sheet No. 352.0.
Damage caused by the use of other reduc-
ing agents will invalidate the New Vehicle
Limited Warranty.
! If DEF comes into contact with a painted
or aluminum surface, wash the surface off
immediately with plenty of water.
High ambient temperatures
When opening the DEF tank filler cap at high
outside temperatures, ammonia vapors may
escape. Ammonia vapors have a pungent
odor and are particularly irritating for your
skin, respiratory organs and eyes. This may
result in burning eyes, nose and throat, as
well as coughing and watering eyes. Do not
inhale ammonia vapors.
If DEF heats up, e.g. in direct sunlight, in the
DEF supply reservoir for some time to over
122 ‡ (50 †), ammonia vapor will develop.
Low ambient temperatures
DEF freezes at a temperature of approx-
imately 12 ‡(00F811 †). The vehicle is equipped
with a DEF preheating system at the factory.
Winter operation is therefore also guaranteed
at temperatures under 12 ‡ (00F811 †).
Additives and tap water
! Do not mix DEF with any additives and do
not dilute DEF with tap water. Otherwise,
the exhaust gas aftertreatment may be
damaged.
Observe the MB Specifications for Service
Products, Sheet No. 352.0.
Damage that arises through the use of addi-
tives or tap water will invalidate the New
Vehicle Limited Warranty. 324
