Mercedes Benz 2003 e 320 User Manual

Engine oils are specifically tested for their 
suitability in our engines. Therefore, use 
only engine oils recommended by 
Mercedes-Benz. Information on recom-
mended brands is available in the Factory 
Approved Service Products Pamphlet, or at 
your authorized Mercedes-Benz Center.

Please follow FSS recommendations for 
scheduled oil changes. Failure to do so 
could result in engine damage not covered 
by the Mercedes-Benz Limited Warranty.

Do not blend oil additives with engine oil. 
They may be harmful to the engine opera-
tion.

Damage or malfunctions resulting from 
blending oil additives are not covered by 
the Mercedes-Benz Limited Warranty.

R-134a (HFC) refrigerant and special PAG 
lubricating oil is used in the air conditioner 
system.

Never use R-12 (CFC) or mineral-based lu-
bricating oil. Otherwise damage to the 
system will occur.

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 re-
placed every two years, preferably in the 
spring.

Only brake fluid approved by 
Mercedes-Benz is recommended. Your au-
thorized Mercedes-Benz Center will pro-
vide you with additional information.
