Viscosity grades for engine oils
Using the chart below, select oil viscosity
according to the lowest air temperature
expected before the next oil change.
Engine oil additives
! Do not blend oil additives with engine oil.
They may damage the engine. Damage or
malfunctions resulting from blending oil
additives are not covered by the Mercedes-
Benz Limited Warranty.
Air conditioning refrigerant
R134a (HFC) refrigerant and special PAG
lubricating oil are used in the air conditioning
system.
! Never use R 12 (CFC) or mineral-based
lubricating oil. Otherwise damage to the
system will occur.
Brake fluid
GWarning!
During vehicle operation, the boiling point of
the brake fluid is continuously reduced
through the absorption of moisture from the
atmosphere.
Under extremely strenuous operating
conditions, this moisture content can lead to
the formation of bubbles in the system, thus
reducing the system’s efficiency.
Therefore, the brake fluid must be replaced
regularly. Refer to your vehicle’s Maintenance
Booklet for replacement interval.
Only brake fluid approved by Mercedes-Benz
is recommended. Any authorized Mercedes-
Benz Center will provide you with additional
information.
Premium unleaded gasoline
GWarning!
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious
personal injury.
Never allow sparks, flames or smoking
materials near gasoline!
Turn off the engine before refueling.
Whenever you are around gasoline, avoid
inhaling fumes and any skin or clothing
contact. Extinguish all smoking materials.
51Restriction: Only SAE 0W-40/SAE 5W-40 engine oils may be used.362Fuels, coolants, lubricants, etc.Technical data

Direct skin contact with fuels and the
inhalation of fuel vapors are damaging your
health.
! To maintain the engine’s durability and
performance, premium unleaded gasoline
must be used.
If premium unleaded gasoline is not
available and low octane gasoline is used,
follow these precautions:
R Have the fuel tank only partially filled
with unleaded regular gasoline and fill up
with premium unleaded gasoline as soon
as possible.
R Avoid full throttle driving and abrupt
acceleration.
R Do not exceed an engine speed of
3 000 rpm if the vehicle is loaded with a
light load such as two persons and no
luggage.
R Do not exceed 2
/ 3 of maximum
accelerator pedal position if the vehicle
is fully loaded or operating in
mountainous terrain.
Fuel requirements
Only use premium unleaded gasoline. The
octane number (posted at the pump) must be
91 min. It is an average of both the Research
Octane Number (RON) and the Motor Octane
Number (MON): (RON+MON)/2. This is also
known as the ANTI-KNOCK INDEX.
Reformulated gasolines (RFG) and/or
unleaded gasoline containing oxygenates
such as ethanol, TAME, ETBE, IPA, IBA, and
TBA can be used provided the ratio of any one
of these oxygenates to gasoline does not
exceed 10%; MTBE must not exceed 15%.
The ratio of methanol to gasoline must not
exceed 3% plus additional cosolvents.
Using mixtures of ethanol and methanol is not
allowed. Gasohol, which contains 10%
ethanol and 90% unleaded gasoline, can be
used.
These blends must also meet all other fuel
requirements, such as resistance to spark
knock, boiling range, vapor pressure, etc.
Diesel engine
Only use commercially available vehicular
ULTRA-LOW SULFUR HIGHWAY DIESEL FUEL
(ULSD, 15 ppm SULFUR MAXIMUM) that
meets the ASTM D975 standard. Failure to
use ULTRA-LOW SULFUR HIGHWAY DIESEL
FUEL (ULSD) can severely damage the
vehicle’s exhaust after-treatment device.
To prevent malfunctions, diesel fuel with
improved cold flow characteristics is offered
in the winter months. Check with your fuel
retailer.
! Do not fill the tank with gasoline. Do not
blend diesel fuel with gasoline or kerosene.
The fuel system and engine will otherwise
be damaged, which is not covered by the
Mercedes-Benz Limited Warranty.
For further information on diesel fuel pump
labeling, contact an authorized Mercedes-
Benz Center or visit www.mbusa.com (USA
only).
Biodiesel (FAME = Fatty Acid Methyl
Ester) containing fuels
Mercedes-Benz USA approves the use of B5
(standard ULSD which may contain a
maximum of 5% biodiesel) in all Common-rail
injection (CDI) and BlueTEC diesel engines.
Diesel fuels containing a higher percentage of
biodiesel, e.g. B20, as well as straight
biodiesel may cause severe damage to your
engine/fuel system and are not approved.
Please ask your service station personnel for
further information. If the B5 biodiesel blend
is not sufficiently labeled to clearly indicate
that it meets the ULSD standard, please do
not use it.

not meeting Mercedes-Benz approved fuel
standards.
Gasoline additives
A major concern among engine
manufacturers is carbon build-up caused by
gasoline. Mercedes-Benz recommends only
the use of quality gasoline containing
additives that prevent the build-up of carbon
deposits.
After an extended period of using fuels
without such additives carbon deposits can
build up, especially on the intake valves and
in the combustion area, leading to engine
performance problems such as:
R Warm-up hesitation
R Unstable idle
R Knocking/pinging
R Misfire
R Power loss
In areas where carbon deposits may be
encountered due to lack of availability of
gasoline which contains these additives, the
use of Mercedes-Benz approved additives is
recommended.
Contact an authorized Mercedes-Benz Center
or visit www.mbusa.com (USA only) for a
listing of approved products. Follow
directions on the product label.
Do not blend other fuel additives with fuel.
This only results in unnecessary cost and may
be harmful to the engine operation.
! Damage or malfunction resulting from
poor fuel quality or from blending additional
fuel additives other than those tested and
approved by us for use on Mercedes-Benz
vehicles are not covered by the Mercedes-
Benz Limited Warranty or by any pre-owned
or Extended Limited Warranties.
AdBlue ®
AdBlue ®
is a non-flammable, non-toxic,
colorless and odorless, water-soluble liquid.
! Only use AdBlue ®
complying with
ISO 22241. Do not blend with additives.
! Rinse surfaces that have come into
contact with AdBlue ®
, or remove AdBlue ®
with a moist cloth and cold water
immediately. If AdBlue ®
has crystallized
already, use cold water and a sponge.
AdBlue ®
residues will crystallize and soil
the affected surfaces.
High ambient temperatures
If AdBlue ®
in the reservoir heats up to above
122‡ (50†) for a long period of time, for
example due to direct sunlight, ammonia gas
vapors may escape when opening the
AdBlue ®
tank.
GWarning!
When opening the filler cap of the AdBlue ®
tank ammonia gas vapors may escape. Refill
AdBlue ®
in a well ventilated area only.
Ammonia gas vapors have a pungent odor and
are particularly irritating for your skin,
mucous membranes, and eyes. Inhaling
ammonia gas vapors will cause burning eyes,
nose, and throat, as well as coughing and
watering eyes.
Low ambient temperatures
AdBlue ®
freezes at a temperature of
approximately 12‡ (-11†). Your vehicle is
factory equipped with an AdBlue ®
preheating
system. The vehicle can thus be operated at
temperatures below 12‡ (-11†).
Special additives
! Only use AdBlue ®
complying with
ISO 22241. Do not add additives to
AdBlue ®
and do not dilute AdBlue ®
with
