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 
required for vehicles with Maintenance 
System. For a listing of approved 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 condition-
ing system. 
Brake fluid
Only brake fluid approved by 
Mercedes-Benz is recommended. Any au-
thorized Mercedes-Benz Center will pro-
vide you with additional information.
!Using engine oils and oil filters of 
specification other than those expressly 
required for the Maintenance System, or chang-
ing 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 Lim-
ited Warranty.
Please follow Maintenance System recommen-
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.
!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 
Warranty.
!Never use R-12 (CFC) or mineral-based lu-
bricating oil. Otherwise damage to the system 
will occur.
Warning!G
During vehicle operation, the boiling point of 
the brake fluid is continuously reduced 
through the absorption of moisture from the 
atmosphere. 
Under extremely strenuous operating condi-
tions, this moisture content can lead to the 
formation of bubbles in the system, thus re-
ducing the system’s efficiency.
Therefore, the brake fluid must be replaced 
regularly. Refer to your vehicle’s Mainte-
nance Booklet for replacement interval.
