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 additivesAir 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

not covered by the Mercedes-Benz Limited

dations for scheduled oil changes. Failure to do 
so will result in engine or emission control sys-
tem damage not covered by the Mercedes-Benz 
Limited Warranty.

They may damage the engine. Damage or mal-
functions resulting from blending oil additives
