More information on engine oil can be

Transmission fluid level
The transmission fluid level does not need
to be checked. If you notice transmission
fluid loss or gear shifting malfunctions,
have an authorized Mercedes-Benz Center
check the automatic transmission.
!Only use approved engine oils. For a
listing of approved engine oils, refer to
the Factory Approved Service Products
pamphlet in your vehicle literature
portfolio.
In addition, check the oil filler cap for
important information pertaining to the
engine oil needing to meet a specific
Mercedes-Benz specification
(e.g. MB 229.5). If such information is
printed on the oil filler cap, only use an
engine oil from the list of approved
engine oils in the Factory Approved
Service Products pamphlet that meets
the specification indicated on the oil
filler cap. Using engine oils of other
specification may cause the FSS to
incorrectly determine the next service
interval and will result in engine dam-
age not covered by the Mercedes-Benz
Limited Warranty.
!Excess oil must be siphoned or drained
off. It could cause damage to the
engine and catalytic converter not
covered by the Mercedes-Benz Limited
Warranty.
