Air conditioning
The air conditioning is operational while
the engine is running and cools the interior

Condensation may drip out from under-

midified.

The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs
which are harmful to the ozone layer.

ditioning is losing refrigerant. The com-
pressor has turned itself off.
Have the air conditioning checked at
