CONTROLS
AND EQUIPMENT
AIR
CONDITIONER*

WARNING
• Good
visibility
comes
with
windows

free
of fog, condensation and
frost.

• For clear
visibility
and safe
driving
it
is
extremely
important
that
you
thor­

oughly
familiarize
yourself
with
and fol­ low the
operating
instructions
pertain­

ing to the proper use and
function
of
the
ventilation/heating,
defogging/de-

frosting
and air conditioning system in

this
manual. If in
doubt,
consult your
Volkswagen
dealer.

The
air conditioning unit is installed under
the roof of the driver's cab. Ten air outlets permit interior cooling throughout the

vehicle.

Two
climate control switches are located
on the instrument panel.

The
unit operates on the air recirculation
principle.
Air is sucked in through the two
large
air intake grilles at the rear portion of
the unit.

Because
the air conditioner is not nor­mally used at low ambient temperatures it

is
designed to operate only when outside
temperature is above 41° F or + 5° C.
When
the air conditioner is on, tempera­
ture as well as humidity inside the vehicle

is
controlled. During high outside humidi­
ty you can prevent windshield and win­

dows
from fogging by setting the controls
accordingly.

Maximum
cooling is maintained with

standard
heating/ventilation controls
turned off and the windows
closed.

However,
when the vehicle interior is very
hot from standing in the sun, open a win­
dow for a few minutes to permit hot air to

escape.
