Checking the oil level using the oil
dipstick
ExampleXPull oil dipstickout of the dipstick guide
tube.
XWipe off oil dipstick.
XSlowly slide oil dipstickinto the guide
tube to the stop, and take it out again.
If the level is between MIN mark"and
MAX mark, the oil level is correct.
XIf the oil level has dropped to MIN mark
"or below, add 1.1 US qt (1.0 liter) of
engine oil.
Adding engine oil
GWARNING
If engine oil comes into contact with hot
components in the engine compartment, it
may ignite. There is a risk of fire and injury.
Make sure that engine oil is notspilled next
to the filler neck. Let the engine cool down
and thoroughly clean the engine oil off the
components before starting the engine.
HEnvironmental 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 that
have been approved for vehicles with a
service system. You can obtain a list of the
engine oils and oil filters tested and
approved in accordance with the
Mercedes-Benz Specifications for Service
Products at any Mercedes-Benz Service
center.
Damage to the engine or exhaust system is
caused by the following:
Rusing engine oils and oil filters that have
not been specifically approved for the
service system
Rreplacing engine oil and oil filters after
the interval for replacementspecified by
the service system has been exceeded
Rusing engine oil additives.
!Do not add too much oil. adding too much
engine oil can result in damage to the
engine or to the catalytic converter. Have
excess engine oil siphoned off.
Example: engine oil capXTurn capcounter-clockwise and remove
it.
XAdd engine oil.
If the oil level is at or below the MIN mark
on the oil dipstick, add 1.1 US qt(1.0 liter)
of engine oil.
XReplace capon the filler neck and turn
clockwise.
Ensure that the cap locks into place
securely.
XCheck the oil level againwith the oil
dipstick (Ypage 282).

Maintenance and care

Engine oil
General notes
!Never use engine oil or an oil filter of a
specificationotherthan 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. You could
otherwise cause engine damage or damage
to the exhaust gas aftertreatment.
Follow the instructions in the service
interval display regarding the oil change.
Otherwise, you may damage the engine and
the exhaust gas aftertreatment.
When handling engine oil, observe the
important safety notes on service products
(Ypage 345).
The engine oils are matched to the
performance of Mercedes-Benz engines and
service intervals. You should therefore only
use engine oils and oil filters that are
approved for vehicles with maintenance
systems.
For a list of approved engine oils and oil filters,
consult an authorized Mercedes-Benz
Center. Or visit the website
http://bevo.mercedes-benz.com.
The table shows which engine oils have been
approved for your vehicle.

Additives
!Do notuse any additives in the engine oil.
This could damage the engine.
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.
Select an engine oil with an SAE classification
(viscosity) suitable for the prevailing outside
temperatures. The table shows you which
SAE classifications are to be used. The low-
temperature characteristics of engine oils
can deteriorate significantly, e.g. as a result
of aging, soot and fuel deposits. It is therefore
strongly recommended that you carry out
regularoil changes using an approved engine
oil with the appropriate SAEclassification.
Brake fluid
GWARNING
The brake fluid constantly absorbs moisture
fromthe air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
fluid is too low, vapor pockets may form in the
brake system when the brakes are applied
