Diesel
Fuel grade
GWARNING
If you mix diesel fuel with gasoline, the flash
point is lower than that of pure diesel fuel.
When the engine is running, exhaust system
components could overheat without being
noticed. There is a risk of fire.
Never refuel with gasoline. Never mix gasoline with diesel fuel.
!Filter the fuel before transferring it to the
vehicle if you are refueling the vehicle from
barrels or containers. This will prevent malfunctions in the fuel sys-
tem due to contaminated fuel.
!You will damage the diesel engine if you do
not refuel with ULSD or a diesel fuel with a
sulfur content of more than 15 ppm.
!Do not use the following:
Rmarine diesel
Rheating oil
Rvegetable oil
Rgasoline
Rparaffin
Rkerosene
Do not mix such fuels with diesel fuel and do
not use any special additives. This can other-
wise lead to engine damage. This does not
include flow improvers. For further informa-
tion, see "Flow improvers".
Usually you will find information about the fuel
grade on the filling pump. If there is no identifi-
cation on the filling pump, consult a gas station
attendant.

Diesel at very low outside temperatures
GWARNING
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, maximum sulfur
content 15 ppm), which fulfills the ASTM D975
standard.
The flow properties of diesel may be inadequate
at low outside temperatures due to paraffin sep-
aration.
iMalfunctions resulting from paraffin sepa-
ration 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 bet-
ter 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 preheating
system. This improves the flow properties of the
diesel by approximately 14.5 ‡ (8 †). ULTRA-
LOW SULFUR DIESEL can be used without risk
of malfunction down to an outside temperature
of approximately 14 ‡ (Ò10 †).
Fuel additives
!Do not add gasoline or kerosene to diesel
fuel to improve its flow characteristics. Gas-
oline or kerosene impairs the lubricating
properties of the diesel fuel. This can result in
damage to the fuel injection system, for
example.
B20 fuels with bio-diesel content
!Continuous use of fuels with bio-diesel con-
tent over 5% (B20 fuels) can lead to fuel filter
clogging. Deposits may also form on the fuel
injector. This may reduce the engine output.
Unburned fuel can get into the oil pan. This
causes the engine oil level to rise. This can
cause engine mechanical damage.
To avoid damages and performance degrada-
tion, observe the following points:
RFill up with fuels with bio-diesel content of
5% (ULSD) or less, whenever possible.
RRegularly monitor your engine oil level if
you use B20 fuels on a regular basis.
RStrictly follow the oil change intervals quo-
ted in the instrument cluster and within
your maintenance booklet.
RUse only engine oils and filters approved for
use in your vehicle.
RIf you do not plan to drive your vehicle for
several weeks, completely fill the fuel tank
in advance with ULSD fuel.
For more information, consult the gas station
staff. The identification of fuels with bio-diesel
content (ULSD or B20) must be clear. If the
marking does not make this clear, do not refuel
from that pump.
Do not refuel with any fuels that have not been
approved for your vehicle.

Information on fuel consumption
HEnvironmental 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:
Refficient use of the fuel by the engine
Rdriving style
Rother 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.
Fuel consumption depends on:
Rthe vehicle version
Rthe style of driving
Rthe operating conditions
Rthe type or quality of the fuel used
The vehicle will use more fuel than usual in the
following situations:
Rat very low outside temperatures
Rin city traffic
Rduring short journeys
Ron mountainous terrain
Rwhen towing a trailer
To keep fuel consumption low, observe the
advice in the "Protection of the environment"
section (
Ypage 25).
The following components of the different vehi-
cle versions influence fuel consumption:
Rtire sizes, tire tread, tire pressure, tire condi-
tion
Rbody
Rtransmission ratios for the drive assemblies
Radditional equipment (e.g. air-conditioning
system, auxiliary heating system)
For these reasons, the actual consumption fig-
ures for your vehicle may deviate from the con-
sumption figures determined according to EU
Directive 80/1268/EE C.
Data concerning fuel consumption are recorded in the on-board computer; use the steering

Diesel Exhaust Fluid (DEF)
General notes
When opening the DEF tank filler cap at high
outside temperatures, ammonia vapors may
escape.
Ammonia vapors have a pungent smell and pri-
marily cause irritation of the:
Rskin
Rmucous membranes
Reyes
You may experience a burning sensation in your
eyes, nose and throat, as well as coughing and
watering of the eyes.
Do not inhale ammonia vapors. Avoid contact
with DEF.
Do not allow DEF to come into direct contact
with your skin; it is hazardous to your health.
Rinse any affected areas off with plenty of clean water. Consult a doctor if necessary.
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.
To conform to emission regulations, you must
operate the vehicle with DEF and refill the supply
regularly. The engine management recognizes
attempts to operate the vehicle without DEF,
with thinned DEF or with another reducing
agent. After previous warning messages, the
engine management then prevents a further
engine start.
When the number of remaining engine starts is 0
the engine management prevents the vehicle
from being driven at a speed exceeding 5 mph
(8 km/h). The multifunction display shows the
Idle Mode
message.
DEF consumption
DEF consumption depends on operational and
driving conditions and it is not necessary to wait
until the next scheduled service to replenish the
fluid. Therefore, refill the DEF supply tank regu-
larly during vehicle operation or, at the latest,
after receiving the first warning message via the
on-board computer.
Low ambient temperatures
DEF freezes at a temperature of approximately
12‡(Ò11 †). The vehicle is equipped with a DEF
preheating system at the factory. Winter oper-
ation is therefore also guaranteed at tempera-
tures under 12 ‡ (Ò11 †).
iIf you add DEF at temperatures below 12 ‡
(Ò11 †) it is possible that the level is not
shown correctly due to the frozen DEF.
Drive for at least 20 minutes (heating phase in
the fuel tank activated) and then stop the
vehicle for at least 30 seconds. The level is
then shown correctly.
Additives
!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 Vehi-
cle Limited Warranty.
Storage
!Containers made of aluminum, copper, cop-
per alloys as well as unalloyed or galvanized
steel are not suitable for storing DEF. If stored
in these types of containers, DEF could cause
constituents of these metals to dissolve and
cause irreparable damage to the exhaust gas
aftertrea tment.
Da
mage caused by such impurities in the DEF
will invalidate the New Vehicle Limited War-
ranty.
Only store DEF in containers made of high-alloy
Cr‑ Ni steel or Mo ‑Cr‑Ni steel in accordance with
DIN EN 10 088 ‑1/2/3 or plastic containers
made of polypropylene or polyethylene.
Purity
!Impurities in DEF (e.g. caused by other ser-
vice products, cleaning agents, dust, etc.)
result in increased emissions, malfunctions,
catalytic converter damage or engine dam-
age.
The purity of DEF is essential to prevent mal-
functions in the exhaust gas aftertreatment.
If DEF is pumped out of the DEF tank, e.g. during
repair work, the same liquid must not be used to
refill the tank. Its purity is no longer guaranteed.

Multi-gr ade engine oils of the prescribed SAE
class (viscosity) may be used all year round, tak-
ing the outside temperatures into account.
Engine oil viscosity
!If the SAE viscosity class of the engine oil
used does not cover the outside temperature
range in which you are operating the vehicle,
it must be changed in good time, in particular
before the cold season commences. Using an
engine oil that does not have adequate tem-
perature characteristics can lead to engine
damage.
The temperature range information of the SAE
classification always refers to that of fresh oil.
The temperature characteristics of the engine
oil may deteriorate significantly due to aging
in use, especially at low outside tempera-
tures.
We recommend that you change the engine
oil before the cold season commences. Use
an approved engine oil of the specified SAE
class.

Engine oil SAE classification
Viscosity indicates the flow characteristics of a
fluid. If an engine oil has a high viscosity, this
means that it is thick; a low viscosity means thatit is thin.
Depending on the respective outside tempera-
tures, select an engine oil according to SAE
classification (viscosity). The table displays the
SAE classification to be used. The low temper-
ature characteristics of engine oils can notice-
ably deteriorate during operation, e.g. from
aging, soot and fuel accretion. For this reason,
regular oil changes using an approved engine oil
from the suitable SAE classification are urgently
recommended.
Additives
!Do not use any additives in the engine oil.
This could damage the engine.
Miscibility of engine oils
!Mixing oils reduces the benefits of using
high grade engine oils.
We recommend that you only add engine oil of
the same quality grade and SAE class as used
when the engine oil was last changed.
If, in exceptional cases, oil of the type in the
engine is not available, top up using another
approved mineral or synthetic engine oil.
If the quality grade is not available for diesel
engines, you may also add engine oils meeting
the requirements in MB Sheet Number 228.5,
229.3 or 229.5. The quantity to be added is then
limited to a maximum of 1 qt (1 l).
Engine oils are differentiated according to:
Rengine oil brand
Rquality grade (sheet number)
RSAE class (viscosity) Subsequently have the engine oil changed at the
earliest possible opportunity.
Interval for oil change
The on-board computer automatically shows
the date for the next oil change as an event
message in the display.
Only by using engine oil with a particularly high
quality grade, e.g. according to Sheet Number
228.51 of the Mercedes-Benz Specifications for
Service Products, can the maximum interval for
oil change be achieved.
We recommend having the oil changed at a
qualified specialist workshop.

Information about oil consumption
!If the vehicle is predominantly used for
short-distance driving, this could lead to a
malfunction in the automatic cleaning func-
tion for the diesel particle filter. As a result,
fuel may accumulate in the engine oil and
cause engine failure.
Therefore, if you mainly drive short distances,
you should drive on a highway or on rural
roads for 20 minutes every 310 miles
(500 km). This ensures sufficient regenera-
tion of the diesel particle filter.
Service products and capacities283
Technical data

Page 286 of 294

Depending on the driving style, the vehicle con-
sumes a maximum of 1.0 qt (1.0l)of engine oil
over a distance of 620 miles (1000 km).
Oil consumption may be higher if:
RThe vehicle is new.
RYou mainly operate the vehicle under arduous
operating conditions.
RYou frequently drive at high engine speeds.
Regular maintenance is one of the preconditions
for moderate rates of consumption.
You can only estimate the oil consumption after
you have driven a considerable distance.
Check the engine oil level on a regular basis, e.g.
weekly or each time you refuel (
Ypage 221).

Brake fluid
GWARNING
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
fluid is too low, vapor pockets may form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There is a risk of an accident.
You should have the brake fluid renewed at
the specified intervals.
!Brake fluid corrodes paint, plastic and rub-
ber. If paint, plastic or rubber has come into
contact with brake fluid, rinse with water
immediately.
When handling, storing and disposing of brake
fluid, please observe the relevant regulations
and the important safety notes for service prod-
ucts.
Over a period of time, the brake fluid absorbs
moisture from the air. This reduces its boiling
point.
Have the brake fluid replaced at specified inter-
vals by a qualified specialist workshop.
iThere is usually a notice in the engine com-
partment to remind you when the next brake
fluid change is due.
Only use brake fluid approved by Mercedes-
Benz in accordance with MB-Freigabe or MB-
Approval 331.0.

Coolant
Important safety notes
GWARNING
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.
!Take care not to spill any coolant on painted
surfaces. You could otherwise damage the
paintwork.
When handling coolant, observe the important
safety notes for service products (
Ypage 278).
Coolant additive with antifreeze
requirements
!Use only approved antifreeze/corrosion
inhibitor that complies with MB Specification for Service Products, Sheet Number 325.
Using other, non-approved antifreeze/corro-
sion inhibitors may cause damage to the cool-
ant system and reduce the engine's service
life.
Coolant is a mixture of water and antifreeze/
corrosion inhibitor. It performs the following
tasks:
RAnti-corrosion protection
RAntifreeze protection
RRaises the boiling point
When the vehicle is first delivered, it is filled with
a coolant mixture that ensures adequate anti-
freeze/corrosion protection. Coolant must be
used in the system all year round to ensure anti-
corrosion protection and a raised boiling point –
even in countries with high outside tempera-
tures. To prevent damage to the engine cooling sys-
tem, use only approved corrosion inhibitor/anti-
freeze that comply with the Mercedes-Benz
Specifications for Service Products.
We recommend corrosion inhibitor/antifreeze
that meets the requirements in MB Specifica-
tions for Service Products Sheet Number 325.
Check the antifreeze/corrosion inhibitor con-
centration in the coolant every six months.
The percentage of corrosion inhibitor/anti-
freeze additive in the engine cooling system
should:
Rbe at least 50%. This way, the engine cooling
system is protected against freezing down to
approximately -35 ‡ (-37 †).
Rnot exceed 55 % otherwise heat will not be
dissipated as effectively. At 55 %,the engine
cooling system is protected against freezing
down to approximately -49 ‡ (-45 †).
If there has been coolant loss, do not refill only
with water. If the vehicle has lost coolant, add
equal parts water and corrosion inhibitor/anti-
freeze additive. The water used as part of the
coolant mixture must fulfill certain require-
ments; these are usually fulfilled by drinking
water. If the water quality is not s
ufficient, you
must treat the water.
