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

Mercedes-Benz Center.

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

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.
!
Never use R-12 (CFC) or mineral-based 
lubricating 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 
Maintenance Booklet for replacement inter-
val.
