Downloaded from www.Manualslib.com manuals search engine Fan Button
The button with the fan symbol adjusts the fan speed.
Press the up arrow to increase fan speed and the down
arrow to decrease fan speed.
Temperature Button
The red and blue temperature buttons adjust the air
temperature coming through the system. Press the blue
button for
a cooler setting or the red button for a warmer
setting. The outside temperature
is always displayed
when your vehicle
is running. You can change it from
Fahrenheit
to Celsius by pressing the ENG/MET
(English/metric) button on the
DIC.
Mode Controls
The AUTO/ECON button automatically controls the
direction of air delivery for air conditioning and non-air
conditioning modes.
Automatic Operation
When the system is set for AUTO, 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
75°F (24°C)
setting, allow about 20 minutes for the system to
regulate. Press the red or blue temperature buttons to
adjust the temperature if necessary. If you choose 60°F
(1 6"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 this 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 the floor outlets.
As the interior temperature approaches a desired setting,
the blower 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 A/C outlets (A/C mode) to maintain
comfort and prevent stuffiness.
