Fan speed at low
2Fan speed at high
The fan speed can be set to your desired
speed by touching the appropriate air flow
control switch. The higher the fan speed is,
the more air is delivered. Pushing the “OFF”
button turns of f the fan.
To remove exterior windshield frost, use the
high speed setting.
The selected mode is highlighted in green. If manual switching of air intake is desired

The air intake control button is used to switch
the air intake between the OUTSIDE AIR
mode and RECIRCULATED AIR mode.
With the button in the OUTSIDE AIR mode,
the OUTSIDE AIR mode indicator light will
come on and the system will take fresh out-
side air into the vehicle.
If quick circulation of cooled air is desired,
push the air intake control button for RECIR-
CULATED AIR. The RECIRCULATED AIR
mode indicator light will come on.
For normal use, it is best to keep
the air intake
control button set to OUTSIDE AIR mode. If
recirculated air is used during heating, the
windows will fog up more easily. If the engine coolant temperature becomes
extremely high, the RECIRCULATED AIR
mode is
automatically selected. This is not a
malfunction. When the engine coolant tem-
perature is lowered, the previous mode re-
sumes.
In the following cases, the RECIRCULATED
mode may change to the OUTSIDE AIR
mode automatically to prevent interior fog.
When the outside temperature becomes
lower than 4 C (39F).
When the air conditioning compressor
malfunctions.
When the air conditioning cooler refriger-
ant decreases.

If manual on off of the air conditioning is
desired
Push the “A/C”
switch to turn the air condi-
tioning on and push it again to turn the air
conditioning off. If you turn off the air condi-
tioning manually, the EXHAUST GAS AUTO-
MATIC mode will be cancelled.
If the outside temperature is lowered down to
around 0 C (32 F), the air conditioning will
turn off automatically. At this time, the indica-
tor on the A/C button is off and the EXHAUST
GAS AUTOMATIC indicator light remains on.
However, the EXHAUST GAS AUTOMATIC
mode does not operate. When the air condi-
tioning turns on as with the raised tempera-
ture, the EXHAUST GAS AUTOMATIC mode
resumes.
If the system is used for ventilation, heating in
dry weather or removing frost or exterior fog
on the windshield, turn the air conditioning off
once it is no longer required. This will improve
fuel economy. The air conditioning can be
used for year−round automatic temperature
control including cooling and dehumidifying
operation.
(b) Windshield defogging and de-
frosting
To remove interior fog on the windshield
Push the “FRONT WINDSHIELD” button.
To remove frost or exterior fog on the
windshield
1. Push the upper side of the temperature
control button until maximum figure appears
on the temperature display.
2. Push the “FRONT WINDSHIELD” but-
ton.
3. Push the “HI” of the air flow control switch
to obtain a maximum air flow.
4. Leave the air conditioning on −off button
off.
For further information for removing frost and
fog, see “Lower vent” on page 139. When the
“FRONT WINDSHIELD” button is
pushed while operating in automatic mode,
the air conditioning is set to operate and the
OUTSIDE AIR mode is set.
Push the “A/C” switch for dehumidified heat-
ing or cooling. This setting clears the front
view more quickly.
If you push the “FRONT WINDSHIELD” but-
ton once again while in the FRONT WIND-
SHIELD mode, the mode then returns to the
last mode used.
CAUTION
Do not use the “FRONT WINDSHIELD”
button during cooled air operation in ex-
tremely humid weather. The difference
between the temperature of the outside
air and that of the windshield could
cause the outer surface of the wind-
shield to fog up blocking your vision.
