Bi-level heating
HB5014AA
This setting allows you to direct air of different temperatures from the
instrument panel and foot outlets. The air from the foot outlets is
slightly warmer than from the instrument panel outlets.
1. Set the air inlet selection button to the “OFF” position.
2. Set the air flow control dial to the “
” position.
3. Set the temperature control dial to the desired temperature level.
4. Set the fan speed control dial to the desired speed.
Setting the temperature control dial fully turned to the red area or blue
area decreases the temperature difference between the air from the
instrument panel outlets and the air from the foot outlets. Ventilation
WARNING
Continued operation in the “ON” position may fog up the win-
dows. Switch to the “OFF” position as soon as the outside dusty
condition clears.

HB5015AA
To force outside air through the instrument panel outlets:
1. Set the air inlet selection button to the “OFF” position.
2. Set the air flow control dial to the “
” position.
3. Set the temperature control dial all the way left.
4. Set the fan speed control dial to the desired speed.
When driving on a dusty road, set the air inlet control lever to the “ON”
position.
Air conditioner operation Cooling or dehumidifying

HB5011BB
To direct warm air to the windshield and front door windows:
1. Set the air outlet control dial to the “ ” position.
2. Set the temperature control dial to the red area.
3. Set the fan speed control dial at the highest speed.

4-12Automatic climate control system (if equipped) NOTE
Operate the automatic climate control system when the engine is
running. When the engine coolant is cold, for instance in cold weather, the
air flows through the windshield defroster outlets and the blowerruns at the lowest speed to prevent cold air from blowing directly
against the driver and front passenger. In the “AUTO” mode, if the air temperature in the passenger
compartment is cooled down to the specified temperature, the air
conditioner compressor stops automatically. For efficient defogging
or dehumidifying in cold weather, press the “A/C” switch on.
Even when cooling is not necessary, setting the temperature
much lower than the current outlet air temperature turns on the airconditioner compressor automatically and the “A/C” indicator light
on the control panel comes on.
The automatic climate control system automatically controls outlet air
temperature, fan speed, air flow distribution air-inlet control, and air con-
ditioner compressor operation. It activates when the “AUTO” switch is
pressed, and is used in conjunction with the Temperature control dial to
maintain a constant, comfortable climate within the passenger compart-ment.
The temperature can be set within a range of 65 – 85 F (18 – 32 C).
NOTE
The temperature is shown in units of Fahrenheit for US model and in Centigrade for Canadian model.

AUTO mode operation:
The Automatic Climate Control system automatically controls the air
temperature of the passenger compartment in the AUTO mode. Whenthe “AUTO” switch is pressed, the indicator light “AUTO” on the con-
trol panel comes on. In this state, outlet air temperature, fan speed, air
flow distribution, air-inlet control, and air conditioner compressor op-
eration are automatically controlled.

4-14ECON (economy) mode:
When you press the
“AUTO” switch while the system is in the AUTO
mode, it selects the ECON (economy) mode, turning on the“
ECON ” indicator light. In the ECON mode, the compressor runs to
be thrifty with energy consumption. Interior windows tend to fog in this
energy-saving operation. It is therefore recommended that the AUTOmode be used only in high humidity conditions. Manual mode operation:
When the Automatic Climate Control system is operating in the AUTO
mode, pressing the “
”, “”, “MODE”, “A/C” or
“
” switch shifts the operation into the “MANUAL” mode and the
indicator light “AUTO” on the control panel will go out.
When the “
”, “”, “MODE”, “A/C” or “”
switch is pressed, the corresponding function can be controlled inde-
pendently, while automatic control of the other functions are main-tained.
To change the system back to the AUTO mode, press the “AUTO”
switch. n OFF switch
The Automatic Climate Control system turns off (the air conditioner
compressor and fan turn off) when the “OFF” switch is pressed.
When the “OFF” switch is pressed, the outside air introduction mode
(“
” position) is automatically selected.
NOTE Display illumination dimness cancellation (BRIGHT): Setting the light switch to the “p ” or “ a ” position causes the
illuminating icons on the display panel to dim. When travelingwith the lights on in gloomy daylight or in twilight, press the OFFswitch for 1 second or longer if you feel it is too hard to identify
the icons clearly. The brightness comes back to normal.If you wish to dim the icons again, hold down the OFF switchagain or if you can safely do so, turn the light switch OFF andthen place it in the “p ” or “a ” position.

OUT.TEMP switch
To check the outside air temperature, push the “OUT.TEMP” switch.
The outside air temperature will be displayed for five seconds, and
then the display automatically changes back to the inside air temper-
ature.
The display changes over from the inside air temperature to the out-
side air temperature as its normal indication if you keep the switch
pressed for more than 2 seconds. NOTE The outside air temperature display shows the outside air tem-
perature in a range from –22F to 131 F ( –30 C to 55 C).
You can check the outside air temperature even when the Au-
tomatic Climate Control is off. (The ignition switch should be in the “ON” position.)
In the following cases, the display can indicate a higher tem-
perature than the actual outside air temperature: – In direct sunlight
– When the vehicle is parked for a long period of time with the
engine kept running.– During stop and go driving
n
— Defroster switch
To defrost or dehumidify the windshield and side window, push the
defroster switch “
”. When the “” switch is pushed, re-
gardless whether the air conditioner is operating or not, outside air is
drawn into the passenger compartment, the air conditioner compres-
sor turns on, air flow is directed towards the windshield and side win-dows, and the indicator light “
” on the control panel comes on.
Even with the defroster switch pushed, you can turn the air condition-
er ON/OFF and select interior air recirculation or outside air introduc-
tion as desired.
After eliminating the fogging from the windshield, set the air condition-er back in the AUTO mode by pushing the “AUTO” switch or turn off
by pushing the “OFF” switch or “
” switch.

Fan speed control switch
HB5021BB
The fan speed control switch has the 5 positions: AUTO position and
4 different fan speed positions.
With the fan speed control switch in the AUTO position, the fan speed
changes automatically corresponding to various conditions: air tem-
perature inside and outside of the passenger compartment, intensityof the sunlight, etc.
Use this switch to select desired fan speed. Fan speed increases with
each press of the switch and returns to the AUTO position. n A/C — Air conditioner switch
NOTE The air conditioner compressor does not operate when the out- side air temperature is below 32 F (0 C).
If the windshield starts to fog when the air conditioner is operated in
the AUTO mode, push the air conditioner switch “A/C” to defog and
dehumidify.
When this switch is pushed, the air conditioner compressor turns onand the indicator light “A/C” on the control panel comes on. After
eliminating the fogging from the windshield, set the air conditionerback in the AUTO mode by pushing the “AUTO” switch.

(Heat-def) : Air flows through the windshield defroster out- lets and foot outlet.
NOTE When the “
” mode is selected, the air conditioner compres-
sor operates automatically regardless of the position of the air
conditioner button to defog the windshield quickly. At the sametime, the air inlet selection is automatically set to “
