Engine oils
Engine oils are specifically tested for
their suitability in our engines and durabil-
ity for our service intervals. Therefore, only
use approved engine oils and oil filters
required for vehicles with
Maintenance System. For a listing of ap-
proved engine oils and oil filters, refer to
the Factory Approved Service Products
pamphlet (USA only), or contact an
authorized Mercedes-Benz Center.
Engine oil additives Air conditioning refrigerant
R-134a (HFC) refrigerant and special
PAG lubricating oil are used in the air con-
ditioning system.
! Using engine oils and oil filters of specifica-
tion other than those expressly required for the
Maintenance System, or changing of oil and oil
filter at change intervals longer than those called
for by the Maintenance System will result in
engine or emission control system damage
not covered by the Mercedes-Benz Limited
Warranty.
Please follow Maintenance System recommen-
dations for scheduled oil changes. Failure to do
so will result in engine or emission control
system damage not covered by the
Mercedes-Benz Limited Warranty.

Do not blend oil additives with engine oil.
They may damage the engine. Damage or mal-
functions resulting from blending oil additives
are not covered by the Mercedes-Benz Limited
