Air conditioning refrigerant
R-134a (HFC) refrigerant and special PAG
lubricating oil are used in the air conditioning
system.
!
Never use R-12 (CFC) or mineral-based
lubricating oil. Otherwise damage to the
system will occur.
Brake fluid
G
Warning!
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
conditions, this moisture content can lead
to the formation of bubbles in the system,
thus reducing the system’s efficiency.
Therefore, the brake fluid must be replaced
regularly. Refer to your vehicle’s
Maintenance Booklet for replacement
interval.
Only brake fluid approved by Mercedes-Benz
is recommended. Any authorized Mercedes-
Benz Center will provide you with additional
information.
