4-44TEMPERATURE CONTROL
KNOBThe temperature control knob (C) is the
round knob closest to the passenger side
of the ventilation control panel. To
change the air temperature in the
passenger compartment, turn the knob
either clockwise for warm to hot air or
counterclockwise for cooler air.
AIR INTAKE
CONTROL SWITCHThis is used to select fresh outside air or
recirculation inside air.
RECIRCULATED AIR
POSITION When the air intake control
switch is depressed (switch indicator
illuminates), almost all outside air flow
into the vehicle is shut off and air inside
the vehicle is recirculated.
This position can be used temporarily for
maximum heating or cooling (if
equipped with air conditioning ) and to
help prevent undesirable outside air flow
into the vehicle.
WARNING
• Continued climate control
system operation in the
recirculated air position may
allow humidity to increase
inside the vehicle which may
fog the glass and obscure
visibility.
 Don’t sleep in a vehicle with
the air conditioning system
on. This could cause serious
harm or death to passengers
due to the depletion of
oxygen and lowering of body
temperature.

• The air conditioning system includes
a function that will automatically turn
the A/C compressor OFF if engine
coolant temperature approaches an
overheating level. A/C compressor
operation will resume once engine
coolant temperature returns to the
“normal” range. Also, the A/C
compressor is automatically turned
off for a few seconds when the
accelerator is fully depressed.
• When operating the air conditioning
system use the outside (fresh) air
position.
• Operating the air conditioning system
in the recirculated air position does
provide maximum cooling, however,
continual operation in this mode may
cause the air inside the vehicle to
become stale.

4-52AIR CONDITIONING
SYSTEM OPERATING
TIPS:• If the vehicle has been parked in
direct sunlight during hot weather,
open the windows for a short time to
let hot air inside the vehicle escape.
• To help reduce moisture on the inside
of windows on rainy, humid days,
decrease the humidity inside the
vehicle by operating the air
conditioning system.
• During air conditioning system
operation, you may occasionally
notice a slight change in engine
speed at idle as the A/C compressor
cycles ON. This is a normal system
operating characteristic.
• Use the air conditioning system every
month if only for a few minutes.
• After air conditioning system use,
you may notice clear water dripping
(or even puddling) on the ground
under the passenger side of the
vehicle. This is a normal system
operating characteristic.• The air conditioning system includes
a function that will automatically turn
the A/C compressor OFF if engine
coolant temperature approaches an
overheating level. A/C compressor
operation will resume once engine
coolant temperature returns to the
“normal” range. Also, the A/C
compressor is automatically turned
off for a few seconds when the
accelerator is fully depressed.
• When operating the air conditioning
system use the outside (fresh) air
position.
• Operating the air conditioning system
in the recirculated air position does
provide maximum cooling, however,
continual operation in this mode may
cause the air inside the vehicle to
become stale.

CAUTION
Do not use defrost position
during cooling operation in
extremely humid weather. The dif-
ference between the temperature of
the outside air and that of the
windshield could cause the outer
surface of the windshield to fog up,
causing loss of visibility. In this
case, set the mode selection knob to
the position and fan speed con-
trol knob to the lower speed.
