Approved engine oils
Engine oils are specifically tested for their
suitability in our engines and durability for
our service intervals. Therefore, only use
approved engine oils and oil filters
required for vehicles with Maintenance
System.
Conventional petroleum-based oils must
not be used for vehicles with Maintenance
System.
For a listing of approved engine oils and oil
filters, contact an authorized
Mercedes-Benz Center or visit
www.mbusa.com (USA only).
Mercedes-Benz recommends
MOBIL 1 OIL. Use the MB sheet number
229.3 and only SAE 5W-50 engine oils.
MB sheet numbers are printed on the out-
side of oil containers.
Engine oil additives
!
Using engine oils and oil filters of
specification other than those expressly re-
quired for the Maintenance System, or changing
of oil and oil filter at change intervals longer than
those called for by the Maintenance System will
result in engine or emission control system dam-
age not covered by the Mercedes-Benz Limited
Warranty.
Please follow Maintenance System recommen-
dations for scheduled oil changes. Failure to do
so will result in engine or emission control sys-
tem damage not covered by the Mercedes-Benz
Limited Warranty.
!
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.

396 Technical dataFuels, coolants, lubricants, etc.Air conditioning refrigerant
R134a (HFC) refrigerant and special PAG
lubricating oil are used in the air condition-
ing system.
Brake fluid
Only brake fluid approved by
Mercedes-Benz is recommended. Any au-
thorized Mercedes-Benz Center will
provide you with additional information.
Premium unleaded gasoline
!
Never use R12 (CFC) or mineral-based
lubricating oil. Otherwise damage to the system
will occur.
Warning!
G
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 Mainte-
nance Booklet for replacement interval.
Warning!
G
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious
personal injury.
Never allow sparks, flame or smoking
materials near gasoline!
Turn off the engine before refueling.
Whenever you are around gasoline, avoid
inhaling fumes and skin or cloth contact,
extinguish all smoking materials.
Direct skin contact with fuels and the
inhalation of fuel vapors are damaging to
your health.

Fuel requirements
Only use premium unleaded fuel:

The octane number (posted at the
p um p) m us t be 91 mi n. It i s an a vera ge
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.
Unleaded gasoline containing oxygenates
such as ethanol, 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.
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:

Warm-up hesitation


Unstable idle


Knocking/pinging


Misfire


Power loss
!
To maintain the engine’s durability and per-
formance, premium unleaded gasoline must be
used. If premium unleaded is not available and
low octane fuel is used, follow these precau-
tions:


Have the fuel tank only partially filled with
unleaded regular gasoline and fill up with
premium unleaded gasoline as soon as
possible.


Avoid full throttle driving and abrupt acceler-
ation.


Do not exceed an engine speed of 3000 rpm
if the vehicle is loaded with a light load such
as two persons and no luggage.


Do not exceed
2/3 of maximum accelerator
pedal position if the vehicle is fully loaded or
operating in mountainous terrain.

398 Technical dataFuels, coolants, lubricants, etc.In areas where carbon deposits may be
encountered due to lack of availability of
gasolines which contain these additives,
Mercedes-Benz recommends the use of
additives approved by us for use on
Mercedes-Benz vehicles. Contact an au-
thorized Mercedes-Benz Center or visit
www.mbusa.com (USA only) for a listing of
approved product(s). Follow directions on
product label.
Do not blend other fuel additives with fuel.
This only results in unnecessary cost and
may be harmful to engine operation.
Coolants
The engine coolant is a mixture of water
and anticorrosion/antifreeze, which pro-
vides:

corrosion protection


freeze protection


boiling protection (by increasing the
boiling point)
The cooling system was filled at the factory
with a coolant providing freeze protection
to approximately -35°F (-37°C) and
corrosion protection.
If the antifreeze mixture is effective to
-35°F (-37°C), the boiling point of the cool-
ant in the pressurized cooling system is
reached at approximately 266°F (130°C).The coolant solution must be used year
round to provide the necessary corrosion
protection and increase in the boil-over
protection. Refer to Maintenance Booklet
for replacement interval.
Coolant system design and coolant used
determine the replacement interval. The
replacement interval published in the
Maintenance Booklet is only applicable if
MB 325.0 Anticorrosion/Antifreeze solu-
tion or other Mercedes-Benz approved
products of equal specification are used to
renew the coolant concentration or bring it
back up to the proper level.
For information on other Mercedes-Benz
approved products of equal specification,
contact an authorized Mercedes-Benz
Center or visit www.mbusa.com
(USA only).
!
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 war-
ranties.
!
Add premixed coolant solution only. Adding
water and MB 325.0 Anticorrosion/Antifreeze
separately from each other, could cause engine
damage not covered by the Mercedes-Benz
Limited Warranty.

399 Technical data
Fuels, coolants, lubricants, etc.
To provide important corrosion protection,
the solution must be at least 50% anticor-
rosion/antifreeze (equivalent to freeze
protection to approximately
-35°F [-37°C]). If you use a solution that is
more than 55% anticorrosion/antifreeze
(freeze protection to approximately
-49°F [-45°C]), the engine temperature
will increase due to the lower heat transfer
capability of the solution. Therefore, do not
use more than this amount of
anticorrosion/antifreeze.If the coolant level is low, water and
MB 325.0 Anticorrosion/Antifreeze
should be used to bring it up to the proper
level (have cooling system checked for
signs of leakage). Please make sure the
mixture is in accordance with label instruc-
tions.
The water in the cooling system must meet
minimum requirements, which are usually
satisfied by normal drinking water. If you
are not sure about the water quality, con-
sult an authorized Mercedes-Benz Center.

400 Technical dataFuels, coolants, lubricants, etc.Anticorrosion/antifreeze
Your vehicle contains a number of alumi-
num parts. The use of aluminum compo-
nents in motor vehicle engines
necessitates that anticorrosion/antifreeze
coolant used in such engines be specifical-
ly formulated to protect the aluminum parts. Failure to use such anticorro-
sion/antifreeze coolant will result in a
significantly shortened service life.
Therefore, the following product is strongly
recommended for use in your vehicle:
MB 325.0 Anticorrosion/Antifreeze agent.Before the start of the winter season (or
once a year in hot southern regions), you
should have the anticorrosion/antifreeze
concentration checked. The coolant is also
regularly checked each time you bring your
vehicle to an authorized Mercedes-Benz
Center for service.
