When checking the oil level:
R
park the vehicle on a level surface.
R the engine should be switched off for approx-
imately five minutes if the engine is at normal
operating temperature.
R if the engine is not at normal operating tem-
perature, e.g. if the engine was only started
briefly, wait about 30 minutes before carrying
out the measurement.
Checking the engine oil level using the
oil dipstick Example: vehicles with a gasoline engine
X Pull out oil dipstick 0043.
X Wipe off oil dipstick 0043.
X Slide oil dipstick 0043into the dipstick guide
tube as far as it will go and take it out again.
If the level is between MIN mark 0087and MAX
mark 0044, the engine oil level is correct.
X If the engine oil level has dropped to MIN mark
0087 or below, add 1.1 US qt (1.0 liter) of engine
oil.
Adding engine oil H
Environmental note
When adding oil, take care not to spill any. If
oil enters the soil or waterways, it is harmful to the environment.
! Use only engine oils and oil filters that are
approved for vehicles with a service system. A list of the engine oils and oil filters that have
been tested and approved in accordance with
Mercedes-Benz Specifications for Service
Products is available at any authorized
Mercedes-Benz Center. The following cause engine failure or damage
to the exhaust system:
R Use of engine oils and oil filters that have
not been expressly approved for the service
system
R Replacement of engine oil and oil filter after
the replacement interval specified by the
service system has expired
R Use of 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 cap
X Turn cap 0043counter-clockwise and remove it.
X Add 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.
X Replace cap 0043on the filler neck and tighten
clockwise.
Ensure that the cap locks into place securely.
X Check the oil level again with the oil dipstick
(Y page 323).
