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 eooler 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
ENGNET
(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.

Downloaded from www.Manualslib.com manuals search engine Electronic Solar Sensor
The sensor monitors the sun’s solar radiation and is
located
on top of the instrument panel near the
windshield. The
ECC system uses this information to
automatically
make the necessary temperature and
airflow adjustments to maintain your
comfort.
Air Conditioning
On hot days, open the windows long enough to let hot
inside
air escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed for the air conditioner to work its best.
Press the
AUTO/ECON button to assist in cooling air
and in maintaining proper airflow. Adjust the
temperature
to a comfortable setting by pressing the
blue button to cool your vehicle
and pressing the red
button to
warm your vehicle. Press the fan button arrows
up or down
to adjust the fan speed.
When the air conditioner is on, you may sometimes
notice slight changes in your vehicle’s engine speed and
power. This is normal because the system is designed to
cycle the compressor on and off to keep the desired
temperature.

Reinstall the clean air duct
over the mass airflow
sensor. Make sure that the duct is secure around the
entire outer edge of the sensor.
Tighten the air duct clamp. Reconnect the
IAT sensor.
Refer to the Maintenance Schedule
to determine when to
replace the air filter.
See “Scheduled Maintenance Services”
in the
Maintenance Schedule booklet.
I A CAUTION:
Operating the engine with the air cleaner off can
cause you or others to be burned. The
air cleaner
not only cleans the air, it stops flames if the
engine backfires.
If it isn’t there, and the engine
backfires, you could be burned. Don’t drive with
it
off, and be careful working on the engine with
the
air cleaner off.
NOTICE:
If the air cleaner is off, a backfire can cause a
damaging engine fire. And, dirt can easily get
into your engine, which will damage it.
Always
have the air cleaner in place when you’re driving.
