kept constant under varying climatic condi-
tions.

is
automatically
mixed by
means
o, air
flaps operated
by
a
servo
motor. The servo
motor
is controlled by
a

sor, an
ambient temperature sensor
and
a
temperature sensor
located
in
the air

Conditioner
AF
The
air
conditioning system
works
only
when the
engine is
running. lts refrigerating
capacity depends on engine speed.
lf
a
high
refrigerating
capacity is desired,
it is neces-
sary
to rev up the engine
-
particularly
in
city
or bumper-to-bumPer
traff ic.
The
air
conditioning system can be turned
on at
any
air
distribution
position
by
pressing
the air
conditioner switch. When
the system is
turned on. the air
conditioning
compressor
is
activated
via
a
magnetic
clutch.
Optimal
cooling
is
achieved
when the
fan
control switch is
at position 4, the windows
are closed and
the lateral as
well as the
