led with refrigerant R‑134a.
The instruction label regarding the refrigerant
type used can be found on the radiator cross

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
