Air conditioning
The air conditioning is operational while
the engine is running and cools the interior
air to the temperature set by the operator.

cle will then no longer be cooled or dehu-
midified.

to continue to heat or ventilate the interior
for up to 30 minutes. This feature makes
use of the residual heat produced by the
engine.

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

If the AC
OFF
button on the automatic
climate control panel starts to blink,
this indicates that the air conditioning
system is losing refrigerant. The com-
pressor has turned itself off. The air
conditioning cannot be turned on
again.
Have the air conditioning system
checked at the nearest authorized
Mercedes-Benz Center.
