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 radiator cross
member.

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.
Service work, such as topping-up refrigerant
or replacing components, may only be carried
out by a qualified specialist workshop. All
