WARNING
cThe air conditioner cooling function
operates only when the engine is
running.
cDo not leave children, unreliable
adults, or pets alone in your vehicle.
On hot, sunny days, temperatures in
a closed vehicle could quickly be-
come high enough to cause severe
or possibly fatal injuries to people or
animals.
cDo not use the recirculation mode
for long periods as it may cause the
interior air to become stale and the
windows to fog up.
cPositioning of the heater and air con-
ditioner controls should not be done
while driving, in order that full atten-
tion may be given to the driving
operation.

the passenger compartment under cold out-
side conditions before the engine is warmed
up.
Air recirculation button
Fresh position (indicator light off):
Outside air is drawn into the passenger
compartment.
Use this position for normal heater or air
conditioner operation.
Recirculate position (indicator light on):
Interior air is recirculated inside the vehicle.
Activate the air recirculation button when
driving on a dusty road or to help keep out
traffic fumes.
Activate the air recirculation button for im-
proved air conditioner performance under high
temperature and high humidity conditions.
If the system is operating in theormode, the system does not allow the
air recirculate mode to be selected.
CAUTION
Do not use the recirculation mode for
long periods as it may cause the inte-
rior air to become stale and the win-
dows to fog up.
Air conditioner button
Start the engine, move the fan control dial to
the desired (one to four) position, select an
air control button and push the air conditioner
button to turn on the air conditioner. The
indicator light comes on when the air condi-
tioner is on. To stop the air conditioner, push
the button again; the indicator light goes off.
The air conditioner cooling function op-
erates only when the engine is running.
HEATER OPERATION
Heating
This mode is used to direct most of the hot
air to the floor outlets.
Push the air recirculation button to the off
position for normal heating.
1. Push the
button in.
2. Turn the fan control dial to select speed.3. Move the temperature control dial to the
desired position.
Ventilation
This mode directs air to the side and center
vents.
1. Push the
button in.
2. Turn the fan control dial to select speed.
3. Move the temperature control dial to the
desired position.
Defrosting or defogging
This mode is used to defrost/defog the
windows.
1. Push the
button in.
2. Turn the fan control dial to select speed.
3. Move the temperature control dial to the
desired position.
When the
button is pushed, the air
conditioner automatically turns on to de-
fog the windshield. The air recirculation
mode automatically turns off to reduce
window fogging.
When
is selected, the air condi-
tioner indicator light does not illuminate
4-4Heater, air conditioner and audio systems
ZX

unless illuminated in the previously se-
lected mode. However, the air condi-
tioner operates to dehumidify if the out-
side temperature is more than 40ÉF
(4ÉC), whether or not the A/C button has
been pressed. Manual selection and illu-
mination of the A/C button does not
override the automatic dehumidifying
which occurs when
is selected.
Operating Tips
Clear snow and ice from the wiper blades
and air inlet in front of the windshield.
This improves defrosting/defogging op-
eration.
Bi-level heating/cooling
The bi-level mode directs air to the side and
center vents and to the floor outlets.
Bi-level is also a cooling mode when high
sun load conditions are present with cool
temperatures.
With the A/C system in operation, this mode
can be used to cool the passenger's or
driver's feet under high temperature condi-
tions.
With the A/C system in operation under high
temperature conditions, improved coolingcan be obtained by pushing the air recircu-
lation button to the on position.
Push the air recirculation button to the off
position when heating is required.
1. Push the
button in.
2. Turn the fan control dial to the desired
position.
3. Move the temperature control dial to the
desired position.
Heating and defogging
This mode heats the interior and defogs the
windshield.
1. Push the
button in.
2. Turn the fan control dial to the desired
position.
3. Move the temperature control dial to the
desired position.
When the
button is pushed, the air
recirculation mode automatically turns
off. Outside air is drawn into the passen-
ger compartment to improve the defog-
ging performance.
Operating tips
cClear snow and ice from the wiper
blades and air inlet in front of the
windshield. This improves heater op-
eration.
cTo defog the side windows more effec-
tively when in bi-level or ventilation
mode, close the center vent and direct
the side vents toward the side windows.
cA slight delay may be experienced when
changing air control buttons. This is not a
problem, it is only the system motors and
solenoids switching from one outlet to
another.
AIR CONDITIONER OPERATION
Start the engine, move the fan control dial to
the desired (one to four) position, and select
an air control button before pushing in the
air conditioner button to activate the air
conditioner. When the air conditioner is on,
cooling and dehumidifying functions are
added to the system operation.
The air conditioner cooling function op-
erates only when the engine is running.
NOTE: When switching air flow outlets, the
A/C system remains activated unless the

A/C button is pressed again to turn it off.
The indicator light on the A/C button re-
mains illuminated unless the button is
pressed to turn it off, or the OFF air control
button is pressed.
Cooling
This mode is used to cool and dehumidify.
1. Push the
button in.
2. Turn the fan control dial to select speed.
3. Push the air conditioner button. The indi-
cator light comes on.
4. Move the temperature control dial to the
desired position.
cFor quick cooling when the outside tem-
perature is high, push the air recirculation
button to the on position. Be sure to
return the air recirculation button to the
off position for normal cooling.
cOpening the windows helps to vent heat
buildup when parked in the sun.
Dehumidified heating
This mode is used to heat and dehumidify.
1. Push the air recirculation button to the off
position.2. Push the
button in.
3. Turn the fan control dial to select speed.
4. Push the air conditioner button. The indi-
cator light comes on.
5. Move the temperature control dial to the
desired position.
Dehumidified defogging
This mode is used to defog the windows
and dehumidify.
1. Push the
button in.
2. Turn the fan control dial to the desired
speed.
3. Move the temperature control dial to the
desired position.
When the
button is pushed, the air
conditioner automatically turns on to de-
fog the windshield, (however, the light
does not illuminate unless illuminated in
the previously selected mode) and the air
recirculation mode automatically turns
off.
Operating tips
cKeep windows and sun roof closed while
the air conditioner is in operation.cAfter parking in the sun, drive for two or
three minutes with the windows open to
vent hot air from the passenger compart-
ment. Then, close the windows. This
allows the air conditioner to cool the
interior more quickly.
cThe air conditioning system should be
operated for about ten minutes at
least once a month. This helps pre-
vent damage to the system due to lack
of lubrication.
cIf the engine coolant temperature gauge
exceeds the H (hot) position, turn the air
conditioner off. See ``If your vehicle over-
heats'' in the ``In case of emergency''
section for additional information.
