Maintenance and care

A qualified specialist workshop, e.g. an
authorized Mercedes-Benz Center, will reset
the ASSYST PLUS service interval display
after the service work has been carried out.
You can also obtain further information on
maintenance work, for example.
Special service requirements
The specified maintenance interval takes only
the normal operation of the vehicle into
account. Under arduous operating
conditions
or increased load on the vehicle,
maintenance work must be carried out more
frequently, for example:
R regular city driving with frequent
intermediate stops
R if the vehicle is primarily used to travel
short distances
R use
in mountainous terrain or on poor road
surfaces
R if the engine is often left idling for long
periods
Under these or similar conditions, have, for
example, the air filter, engine oil and oil filter
replaced or changed more frequently. Under
arduous operating conditions, the tires must
be checked more often. Further information
can be obtained at a qualified specialist
workshop, e.g. an authorized Mercedes-Benz
Center.
Driving abroad An extensive Mercedes-Benz Service network
is also available in other countries. You can
obtain further information from any
authorized Mercedes-Benz Center. Engine compartment

General notes on the oil level Depending on the driving style, the vehicle
consumes up to 0.9 US qt
(0.8 liters) of oil
over a
distance of

600 miles (1,000 km). The300
Engine compartment
Maintenance and care

oil consumption may be higher than this when
the vehicle is new
or
if you frequently drive at
high engine speeds.
Depending on the engine, the oil dipstick may
be in a different location.
When checking the oil level:
R park the vehicle on a level surface.
R the engine should be switched off for
approximately five minutes if the engine is
at normal operating temperature.
R if the engine is not at normal operating
temperature, e.g. if the engine was only
started briefly: wait about 30 minutes
before carrying out the measurement.
Checking the oil level using the oil
dipstick Example: vehicles with a gasoline engine
Example: vehicles with a diesel engine
X
Park the vehicle on a level surface. To check the oil level with the engine at
operating temperature, switch the engine
off
and wait for
approximately
five minutes.
X Pull oil dipstick 0043 out of the dipstick
guide
tube.
X Wipe off oil dipstick 0043.
X Slowly slide oil dipstick 0043 into the guide
tube to the stop, and take it out again.
If the level is between MIN mark 0087 and
MAX mark 0044, the oil level is correct.
X If the oil level has dropped to MIN mark
0087 or below, add 1.1 US qt (1.0 liter) of
engine oil.
Adding engine oil G
WARNING
If engine oil comes into contact with hot
components in the engine compartment, it
