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 after
having exceeded the interval for
replacement prescribed by the
maintenance system
Rusing engine oil additives
Engine oil cap (example)
Engine oil cap (AMG vehicles, example: 8-cylinderengine)
XTurn cap : counter-clockwise and remove
it.
XAdd the amount of oil required.
Observe the specifications in the on-board
computer when doing so or fill carefully to the
maximum mark on the oil dipstick.
iVehicles with a dipstick: the 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).
iAMG vehicles with 8-cylinder engines: the
difference in quantity between the MIN
mark and the MAX mark on the dipstick is
approximately 1.6 US qt (1.5 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 471).
XReplace cap : on the filler neck and
tighten clockwise.
Ensure that the cap locks into place
securely.
Checking and adding other service
products
Check coolant level
Only check the coolant level when the vehicle
is on a level surface and the engine has cooled
down.
XTurn the key to position 2 (Y page 267) in
the ignition lock.
On vehicles with KEYLESS-GO, press the
Start/Stop button twice (Y page 267).
XCheck the coolant temperature display in
the instrument cluster.
The coolant temperature must be below
158 ‡ (70 †).
GWarning
In order to avoid any potentially serious burns:
Ruse extreme caution when opening the
hood if there are any signs of steam or
coolant leaking from the cooling system, or
if the coolant temperature display indicates
that the coolant is overheated.
Rdo not remove the pressure cap on the
coolant reservoir if the coolant temperature
is above 158 ‡ (70 †). Allow the engine to
cool down before removing the cap. The

RETBE

R TBA
For MTBE, the concentration should not
exceed 15%.
The concentration of methanol in gasoline
including other additives must not exceed 3%.
Using mixtures of methanol and ethanol is not
permitted. Gasohol, a mixture of 10% ethanol
and 90% unleaded gasoline can be used.
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:

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.
