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.
Using engine oils and oil filters of specifica-
tion other than those expressly required 
for the Maintenance System (U.S. vehi-
cles) or FSS PLUS (Canada vehicles), or 
changing of oil and oil filter at change inter-
vals 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 scheduled oil chang-
es. Failure to do so could result in engine 
damage not covered by the 
Mercedes-Benz Limited Warranty.
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. Under extremely strenu-
ous operating conditions, this moisture 
content can lead to the formation of bub-
bles in the system, thus reducing the sys-
tem’s efficiency. Therefore, the brake fluid 
must be replaced every two years, prefera-
bly in the spring.Only brake fluid approved 
by Mercedes-Benz is recommended. Your 
authorized Mercedes-Benz Center will pro-
vide you with additional information.
