Air conditioning

The air conditioning is operational while
the engine is running and cools the interior
air to the temperature set by the operator.
In addition, the air conditioning dehumidi-
fies the interior air at outside temperatures
above 41°F (5° C) and helps prevent
window fogging.
i
Condensation may drip out from under-
neath the vehicle. This is normal and
not an indication of a malfunction.
Warning!
If you turn off the cooling function, the
interior air is not dried. The windows can fog
up more quickly. Window fogging may im-
pair visibility and endanger you and others.
