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.

The sensitivity of the switches is set to be higher toward “HI”
and lower toward “LO”.

If air flow control is not satisfactory, check the center
vents, side vents and rear vents. They may be opened or
closed as shown.
When outside temperature is low like a winter season, air flow
temperature from the center vents, side vents and rear vents
may not be warmed up enough for a while until the engine
coolant temperature becomes high enough.
If air flow from the center vents, side vents and rear vents is not
satisfactory, air flow direction can be changed manually by
adjusting the vents fin direction or the vents may be closed.
