Mercedes-Benz. Information on approved
engine oils is available in the Factory Ap-
proved Service Products pamphlet, or at
your authorized Mercedes-Benz Light
Truck Center.Please follow the FSS and Service Booklet
recommendations for scheduled oil chang-
es. Failure to do so could result in engine

1Use MB Windshield Washer Concentrate “S” and water for temperatures above freezing point or MB Windshield Washer Concentrate “S” and commercially available
premixed windshield washer solvent / antifreeze for temperatures below freezing point. Follow suggested mixing ratios (page 339).
!Always check the oil filler cap
(page 232) for important informa-
tion pertaining to the engine oil need-
ing 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 deter-
mine the next service interval and will
result in engine damage not covered by
the Mercedes-Benz Limited Warranty.
