Spare wheel
! Compare the recommended tire inflation pressure for your vehicle with the tire inflation
pressure on the yellow label located on the spare wheel rim.
If
the tire inflation pressure on the yellow label on the spare wheel rim differs from the values
given in this Operator’s Manual, inflate the tire to the recommended tire inflation pressure
given on the yellow label on the spare wheel rim.
i Please note that the tire inflation pressure of the spare wheel differs from the tire inflation
pressure of the road tires. CLS 550 (all models) CLS 63 AMG CLS 63 AMG

products tested and approved by Mercedes-
Benz.
For information on tested and approved
products, contact an authorized Mercedes-
Benz Center or visit www.mbusa.com (USA
only). G
Warning!
Comply with all valid regulations with respect
to handling, storing, and disposing of service fluids. Otherwise you could endanger persons
or the environment.
Keep service fluids out of the reach of
children.
For health reasons, you should prevent
service

fluids from coming into direct contact
with your skin or clothing.
If a service fluid is swallowed, contact a
physician immediately.

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 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 not
covered 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.

MB sheet numbers are printed on the
outside of oil containers. 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
G
Warning!
During vehicle operation, the boiling point of
the brake fluid is continuously reduced
through the absorption of moisture from the
atmosphere.
36 Restriction: Only SAE 0W-40/SAE 5W-40 engine oils may be used. 298

Version: 2.11.8.1 2009-05-11T16:21:02+02:00 - Seite 298

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
G
Warning!
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:
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. 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. Fuels, coolants, lubricants, etc.
