Automatic Operation
When the system is set for automatic operation,
sensors will control the air delivery mode. Air will
come from the floor, middle or windshield outlets.
The fan speed will vary as the system maintains the
selected temperature setting.
Be careful not to put anything over the solar sensor
located in the middle of the instrument panel near the
windshield. This sensor is used by the automatic system
to regulate temperature.
To find your comfort zone, start with the 75
_F (24_C)
setting and allow about 30 minutes for the system to
regulate. Turn the TEMP/AUTO knob to adjust the
temperature if necessary. If you choose 60
_F (16_C),
the system will remain at that maximum cooling setting
and will not regulate fan speed. If you choose the
temperature of 90
_F (32_C), the system will remain
at that maximum heating setting and will not regulate
fan speed. Choosing either maximum setting will not
cause the system to heat or cool any faster.
With the automatic setting, the air conditioning
compressor automatically cycles when needed to cool
the air. In cold weather, when the system senses the
need for heat, the airflow will be directed out of the
floor outlets. As the interior temperature approaches a
desired setting, the fan speed will decrease. To maintain
interior comfort, the airflow may move to the instrument
panel air outlets and floor outlets (bi
-
level mode).
On bright sunny days in cold weather, the airflow may
come out of the air conditioning outlets (AC mode) to
maintain comfort and prevent stuffiness.
If your vehicle is sitting out on a hot day and you
have it set on AUTO, the air will first flow out the
floor air outlets for a few seconds. That is normal.
This is to expel hot air from the air outlets. As the
air is cooled, the airflow will move through the air
conditioning outlets. If you start your vehicle with the
fan setting on HI, it will skip the air conditioning purge.
