WARNING
Windshield washer concentrate could ignite if
it comes into contact with hot engine compo-
nents or the exhaust system. There is a risk of
fire and injury.
Make sure that no windshield washer con-
centrate is spilled next to the filler neck.

led with refrigerant R‑134a.
The instruction label regarding the refrigerant
type 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.
Service work, such as topping up refrigerant or
replacing components, may only be carried out
by a qualified specialist workshop. All applicable
regulations, as well as SAE standard J639, must
be adhered to.
