the engine is running and cools the interior

Condensation may drip out from under-
neath the vehicle. This is normal and
not an indication of a malfunction.

on again, this indicates that the air con-
ditioning is losing refrigerant. The com-
pressor has turned itself off.
Have the air conditioning checked at
the nearest authorized Mercedes-Benz
