Engine oils
Engine oils are specifically tested for their
suitability in our engines and durability for
our service intervals. Therefore, only use
approved engine oils and oil filters re-
quired for vehicles with Maintenance
System (U.S. vehicles) or FSS (Canada
vehicles). For a listing of approved engine
oils and oil filters, refer to the Factory Ap-
proved Service Products pamphlet, or
contact an authorized Mercedes-Benz
Center.
Engine oil additives
Do not blend oil additives with engine oil.
They may damage the engine.
Damage or malfunctions resulting from
blending oil additives are not covered by
the Mercedes-Benz Limited Warranty.
Air conditioning refrigerant
R-134a (HFC) refrigerant and special PAG
lubricating oil are used in the air
conditioning system.
Never use R-12 (CFC) or mineral-based
lubricating oil. Otherwise damage to the
system will occur.
!Using engine oils and oil filters of specifica-
tion other than those expressly required for the
Maintenance System (U.S. vehicles. Canada ve-
hicles, depending on vehicle production date) or
FSS (Canada vehicles, depending on vehicle pro-
duction date), or changing of oil and oil filter at
change intervals longer than those called for by
the Maintenance System (U.S. vehicles. Canada
vehicles, depending on vehicle production date)
or FSS (Canada vehicles, depending on vehicle
production date) will result in engine or emission
control system damage not covered by the
Mercedes-Benz Limited Warranty. Please follow Maintenance System
(U.S. vehicles. Canada vehicles, depending on
vehicle production date) or FSS (Canada vehi-
cles, depending on vehicle production date)
recommendations 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.
