Climate control system refrigerant
Important safety notes
The climate control system of your vehicle is
filled with refrigerant R‑134a.
The instruction label regarding the refrigerant
type used can be found on the left, on the
underside of the hood.
! 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. Other-
wise, the climate control system may be
damaged.
Service work, such as topping up refrigerant
or replacing components, may only be carried
out by a qualified specialist workshop. All
applicable regulations must be adhered to,

Always have work on the climate control sys-
tem carried out at a qualified specialist work-
