AIR CONDITIONING
263

The “Floor/Windshield” air flow mode may be applied
automatically, if the outside temperature is lowered
down to below 0C (32F).
This is not a malfunct ion. The “Floor/Windshield” air
flow mode turns on the defogging and defrosting
function with the purpose of clearing your front view
for safe driving.
If the “Floor” air flow mode is desired with the main
purpose of heating, “Floor” air flow mode can be
selected manually by touching the air flow control
switch.
G21004
2. Use the “TEMP” or ”PASSENGER TEMP” buttons to set
the desired vehicle interior temperature.
The “TEMP” or “PASSENGER TEMP” (“
”, “”) buttons are
used to set the desired interior temperature. The interior
temperature will be controlled on the driver and passenger side
simultaneously or individually.
To increase the interior temperature, push the “
” button, to
decrease it, push the “” button.
If quick heating or cooling is desired—
“LO” appears when you hold “
” until maximum cooling, and
“HI” appears when you hold “” until maximum heating.
“TEMP” buttons—Changes the temperature on the driver
and passenger sides simultaneously or the driver side only.
“PASSENGER TEMP” buttons—Changes the temperature
settings separate from the driver side.

AIR CONDITIONING
264“DUAL” switch—
This switch is used to set the temperatures independently for
the driver’s seat and front passenger seat.
Touching the switch changes from the independent mode to
the linked mode.

Independent mode: Temperatures can be set
independently for the driver’s seat and front passenger’s
seat. The indicator light will come on to show that the
independent mode has been selected.
 Linked mode: The same temperature is set for the driver’s
seat and front passenger’s seat. The indicator light will turn
off to show that the simultaneous temperature setting mode
has been selected.
When the temperature for the front passenger’s seat is
changed in linked mode, the mode is changed automatically to
independent mode.
INFORMATION
Knowledge for the twotemperature selector operation
This air conditioning system has two independent
temperature selectors: left and right (for the use of
driver and front passenger respectively).
 There are cases where the temperature of the air flow
may not accurately correlate on the driver and front
passenger side according to circumstances, even if
the left and right temperature selectors are set at the
same temperature. If this situation occurs, use the
fine tune operation to adjust the air temperature on
one side.
 There are cases where one or both of the air flow
temperatures may not accurately correlate with the
set temperature according to circumstances, when
the air flow temperature settings on the left and right
are substantially different. For example, if the left
controller is set at central or neutral temperature
while the right one is set at maximum heating or
maximum cooling, or vice versa. If this situation
occurs, use the fine tune operation to adjust the air
temperature on each side.

AIR CONDITIONING
267
To prevent fogging up of the windshield, the air intake mode
may change automatically to the OUTSIDE AIR mode
depending on the condition of the air conditioning system.
For example, when the ambient temperature is low, the air
intake mode may change automatically to the OUTSIDE AIR
mode. This is not a malfunction.
When the air conditioning is on, if the engine coolant
temperature becomes extremely high, the RECIRCULATED
AIR mode is automatically selected. This is not a malfunction.
When
the engine coolant temperature is lowered, the previous
mode resumes.
Turning off the air conditioning manually will cancel the
EXHAUST GAS AUTOMATIC mode. If you select the “AUTO”
mode during fan operating, the air conditioning turns on and
the EXHAUST GAS AUTOMATIC mode will operate.
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. To change the sensitivity of the sensor switching between
the RECIRCULATED AIR and OUTSIDE AIR in the
AUTOMATIC mode, push the air intake control button and
hold it for a few seconds. The display changes to the one
illustrated below.
The sensitivity of the sensor can be adjusted only while the
vehicle has been stopped.
G21023
The sensitivity of the switches is set to be higher toward “HI”
and lower toward “LO”.
Touch the desired switch on the screen.
When
you push any button except the air intake control button,
the above screen goes off.
