(c) Air intake selector
1RECIRCULATED — Recirculates the
air inside the vehicle.
2FRESH — Draws outside air into the
system.
Each time you push the air intake control
button.
The mode changes in order from the RECIR-
CULATED mode to FRESH mode, then back
to the RECIRCULATED mode.
Each indicator light shows which mode is now
selected.
If quick circulation of cooled air is desired,
push the air intake selector button for RECIR-
CULATED mode.For normal use, it is best to keep the air intake
selector button set to the FRESH mode. If re-
circulated air is used during heating, the win-
dows will fog up more easily.
To prevent fogging up of the windshield, the
air intake mode may change automatically to
the FRESH mode depending on the condition
of the air conditioning system.
For example, when the ambient temperature
is low, the air intake mode may change auto-
matically to the FRESH mode. This is not a
malfunction.
When the air conditioning is ON, if the engine
coolant temperature becomes extremely
high, the RECIRCULATED mode is automati-
cally selected. This is not a malfunction.
When the engine coolant temperature is low-
ered, the previous mode resumes.(d) Onoff of the air conditioning
Touch the “A/C” switch.
To turn the air conditioning on and touch it
again to turn the air conditioning off.
The air conditioning does not work if the out-
side temperature is lowered down to around
0C (32F).
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.
If the air conditioning compressor does not
operate, the display light of the “A/C” switch
will blink. If the display light of the “A/C” switch
blinks even when the “A/C” switch is touched
again, have the compressor checked by your
nearest dealer.
If the engine coolant temperature becomes
extremely high, the air conditioning may shut
off automatically to resolve emergency situa-
tion for engine cooling. This is not a malfunc-
tion. When the engine coolant temperature is
lowered, the air conditioning comes on auto-
matically.

164 For manual operation —
Fan speed — To the desired fan speed
Temperature — Towards high temperature
to heat;
low temperature to cool
Air intake — FRESH (outside air)
Air flow — WINDSHIELD
When the windshield air flow button is
pushed, air flows mainly from the windshield
vents and turns on the defogging function with
the purpose of clearing the front view.
Pushing this button once again returns the air
flow mode to the last one used.
This button allows the air intake to select
FRESH mode automatically. This is to clean
up the front view more quickly.
It is not possible to return to RECIRCULATE
in this mode.
Touch the “A/C” switch for dehumidified heat-
ing or cooling. This setting clears the front
view more quickly.
On humid days, do not blow cold air on the
windshield — the difference between the
outside and inside temperatures could
make the fogging worse.— The outside of the windshield
For best results, set controls to:
For automatic operation —
Temperature — Towards high temperature
Air intake — FRESH (outside air)
Air flow — WINDSHIELDFor manual operation —
Fan speed — To the desired fan speed
Temperature — Towards high temperature
Air intake — FRESH (outside air)
Air flow — WINDSHIELD
When the windshield air flow button is
pushed, air flows mainly from the windshield
vents and turns on the defrosting function with
the purpose of clearing the front view.
Pushing this button once again returns the air
flow mode to the last one used.
This button allows the air intake to select
FRESH mode automatically. This is to clean
up the front view more quickly.
It is not possible to return to RECIRCULATE
in this mode.
Touch the “A/C” switch for dehumidified heat-
ing or cooling. This setting clears the front
view more quickly.
To heat the vehicle interior while defrost-
ing the windshield, choose floor/wind-
shield air flow.
— Side vents
If air flow control is not satisfactory, check
the side vents. The side vents may be
opened or closed as shown.
When outside temperature is cold like a winter
season, air flow temperature from the side
vents may not be warmed up enough for a
while until that the engine coolant tempera-
ture becomes high enough.
If air flow from the side vents is not satisfacto-
ry, air flow direction can be changed manually
by adjusting the vents fin direction or the vents
may be closed.
