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 Sys-
tem (U.S. vehicles) or FSS PLUS (Canada 
vehicles). For a listing of approved engine 
oils and oil filters, refer to the Factory Ap-
proved Service Products pamphlet, or con-
tact 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 condition-
ing system.
Never use R-12 (CFC) or mineral-based lu-
bricating oil. Otherwise damage to the 
system will occur.
Brake fluid
During vehicle operation, the boiling point 
of the brake fluid is continuously reduced 
through the absorption of moisture from 
the atmosphere.
Only brake fluid approved by 
Mercedes-Benz is recommended. Your au-
thorized Mercedes-Benz Center will pro-
vide you with additional information.
!Using engine oils and oil filters of spec-
ification other than those expressly re-
quired for the Maintenance System 
(U.S. vehicles) or FSS PLUS (Canada 
vehicles), or changing of oil and oil filter 
at change intervals longer than those 
called for by the Maintenance System 
(U.S. vehicles) or FSS PLUS (Canada 
vehicles) will result in engine damage 
not covered by the Mercedes-Benz 
Limited Warranty.
Please follow Maintenance System 
(U.S. vehicles) or FSS PLUS (Canada 
vehicles) recommendations for sched-
uled oil changes. Failure to do so could 
result in engine damage not covered by 
the Mercedes-Benz Limited Warranty.
Warning!
G
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.
