Adding engine oilHEnvironmental note
When adding oil, take care not to spill any. If
oil enters the soil or waterways, it is harmful
to the environment.
! Only use engine oils and oil filters which
have been approved for vehicles with a
service system. A list of the engine oils and
oil filters that have been tested and
approved according to the Mercedes-Benz
specifications for service products can be
found on the Internet at http://
www.mbusa.com (USA only). Further
information on tested and approved engine
oils and oil filters can be obtained from any
authorized Mercedes-Benz Center.
The following causes engine failure or
damage to the exhaust system:
Rusing engine oils and oil filters that are
not specifically approved for the service
system
Rreplacing the engine oil and oil filter later
than the specified replacement interval
required by the service system
Rusing engine oil additives
Example: engine oil cap
Engine oil cap (AMG vehicles)
XTurn cap : counter-clockwise and remove
it.
XAdd the amount of oil required.
Fill carefully to the maximum mark on the oil
dipstick.
iThe difference in quantity between the
MIN mark and the MAX mark on the
dipstick is (depending on the engine)
approximately 1.6 to 2.1 US qt. (1.5 to 2 l).
! Do not add too much oil. If the oil level is
above the MAX mark on the dipstick, too
much oil has been added. This can lead to
damage to the engine or the catalytic
converter. Have excess oil siphoned off.
Further information on engine oil
(Y page 308).
XReplace cap : on the filler neck and
tighten clockwise.
Ensure that the cap locks into place
securely.
Checking and adding other service
products
Checking the coolant level
Only check the coolant level when the vehicle
is on a level surface and the engine has cooled
down.
XTurn the SmartKey to position
2(Y page 131) in the ignition lock.

All of these mix fuels must fulfill the fuel
requirements, e.g.:
R knock resistance
R boiling point
R vapor pressure
Additives in gasoline
One of the major problems in engine design
is the creation of carbon deposits during the
process of burning fuel. Mercedes-Benz
recommends that you use fuel brands that
have the additives which prevent the build up
of carbon deposits.
If you use fuels without these additives for a
longer period of time, there may be a build up
of carbon deposits, especially on the inlet
valves and in the combustion chamber.
This could lead to engine running problems,
e.g.:
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,
Mercedes-Benz recommends the use of
additives approved for use in Mercedes-Benz
vehicles.
Consult an authorized Mercedes-Benz Center
or visit http://www.mbusa.com (USA only)
to view a list of approved products. Observe
the instructions for use on the product label.
Do not mix other fuel additives with fuel. This
causes unnecessary costs and could damage
the engine.
! Do not refuel with low-grade fuel and do
not use fuel additives that are not tested
and approved for Mercedes-Benz vehicles.
Damage or malfunctions can result that are
not covered:
R by the Mercedes-Benz Limited Warranty
R by an existing Limited Warranty
R by an extended Limited Warranty
Engine oil
Points to remember
The engine oils are matched to the
performance of Mercedes-Benz engines and
service intervals. For this reason, only use
engine oils and oil filters that are approved for
vehicles with a service system.
Contact an authorized Mercedes-Benz Center
or visit http://www.mbusa.com (USA only)
for a list of approved engine oils and oil filters.
! Never use engine oil or an oil filter of a
specification other than is necessary to
fulfill the prescribed service intervals. Do
not change the engine oil or oil filter in
order to achieve longer replacement
intervals than those prescribed. Otherwise,
you may cause damage to the engine or
exhaust gas aftertreatment; this is not
covered by the Mercedes-Benz Limited
Warranty.
Follow the instructions in the service
interval display regarding the oil change.
Otherwise, you may damage the engine and
the exhaust gas aftertreatment.
Mercedes-Benz recommends MOBIL OIL.
The table shows which engines oil have been
approved for your vehicle.

Lubricant additives
! Do not mix any lubricant additives with
the engine oil. This could damage the
engine. Damage resulting from the use of
such lubricant additives in the engine oil is
not covered by the Mercedes-Benz Limited
Warranty.
Engine oil viscosity
Viscosity describes the flow characteristics
of a fluid. If an engine oil has a high viscosity,
this means that it is thick; a low viscosity
means that it is thin.
Using the table below, make sure that the SAE
classification (viscosity) is sufficient for the
temperatures at which the vehicle is
operated. The low temperature
characteristics of engine oils can deteriorate
significantly, e.g. by aging, soot and fuel
deposits. It is therefore recommended that
you carry out oil changes regularly using an
approved engine oil with the appropriate SAE
classification.
Refrigerant of the air-conditioning
system
The air-conditioning system is filled with
R134a refrigerant and a special PAG
lubricant.
! Never use refrigerant R 12 (CFC) or
mineral lubricants. Otherwise, you could
damage the air-conditioning system.
Brake fluid
GWarning!
The brake fluid constantly absorbs moisture
from the air; this lowers its boiling point.
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 (e.g. when
driving downhill). This would impair braking
efficiency.
You should have the brake fluid renewed at
regular intervals. The brake fluid change
intervals can be found in the Service Booklet.
Only use brake fluid approved by Mercedes-
Benz. Information about approved brake
fluids can be obtained from any authorized
Mercedes-Benz Center.
