conjunction with the driving safety systems
on your vehicle such as the ABS or the
ESP ®
. Tires specially developed for your
vehicle and tested and approved by
Mercedes-Benz can be identified by finding
the following on the tire’s sidewall:
R MO =
Mercedes-Benz Original
equipment tires
R MO1 =
Mercedes-Benz Original
equipment tires (applicable to selected
tire sizes only)
R MOE =

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 the 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).
! Using engine oils and oil filters of a
specification other than those expressly
required 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 damage notcovered by the Mercedes-Benz Limited
Warranty.
Please follow Maintenance System
recommendations for scheduled oil
changes. Failure to do so will result in
engine or emission control system damage
not covered by the Mercedes-Benz Limited
Warranty.
Mercedes-Benz recommends MOBIL OIL.

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 fluidGWarning!
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.
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:
RHave the fuel tank only partially filled
with unleaded regular gasoline and fill up
43Restriction: Only SAE 0W-40/SAE 5W-40 engine oils may be used.306Fuels, coolants, lubricants, etc.Technical data

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.
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.
Coolants
The engine coolant is a mixture of water and
anticorrosion/antifreeze, which provides:
R Corrosion protection
R Freeze protection
R Boiling protection (by increasing the boiling
point)
The cooling system was filled at the factory
with a coolant providing freeze protection to
