8Index

Check the antifreeze/corrosion inhibitor con-
centration inthe coolant every six months.
The percentage of corrosion inh ibitor/ant i-
freeze additiveinthe engine co oling system
should:
Rbe at least 50 %.This way, the engine co oling
system isprotected against freezing downto
approximate ly-35 ‡ (-37 †).
Rnot exceed 55% (antifreeze protection down
to -49 ‡ [-45 †]). Other wise, heat will not be
dissipated as effectively.
Mercedes-Benz recommends an antifreeze and
corrosion inhibitor that meets the requirements
in the Mercedes-Benz Specifications for Service
Products Sheet Number 325.
More information can be obtained at any quali-
fied specialist workshop.

Important safety notes
The climate control system of your vehicle is fil-
led with the refrigerant R‑ 134a.
The warning label for the refrigerant being used
can be found on the radiator cross member.
!Only the refrigerant R ‑134a and the PAG oil
approved by Mercedes-Benz may be used.
The approved PAG oil may not be mixed with
any other PAG oil that is not approved for
R-134a refrigerant. Otherwise, the climate
control system may be damaged. Maintenance work such as adding refrigerant or
replacing components may only be carried out
by a qualified specialist workshop. All applicable
regulations thereto and the SAE standard J639
must be adhered to.
All work on the climate control system should
always be carried out at qualified specialist
workshop.
