Downloaded from www.Manualslib.com manuals search engine Temperature Knob Mode Knob - Automatic Operation
The middle knob on the control panel lets you select the
desired air temperature in your vehicle. This knob will
allow
you to adjust the interior air temperature
independently
of the function knob setting. Move the
knob to the right toward
82 for warmer air. Move the
knob to the left toward 66 for cooler air.
Full Hot: If you turn the temperature knob past 82°F
(28”C), the system will go into the
“full hot” mode. The
system will remain at that maximum heating setting and
the fan will blow at the speed the fan knob is set to. If
the fan is in AUTO, it will run at
full speed.
Full Cold: If you turn the temperature knob past 66°F
(1 9”C), the system will go into the “full cold” mode.
The system will remain at that maximum cooling setting
and the fan will blow at the speed the fan knob is set to. \
If the fan is in AUTO, it will run at
full speed.
Choosing either maximum setting will
not cause the
system to heat or cool any faster. The right knob
on the control panel allows you to
choose the direction of air delivery. When the system is
set for automatic operation, sensors will control the air
delivery mode. Air will come primarily from the floor or
instrument panel outlets, with some air directed to the
windshield
to prevent fogging.
When the system is
in AUTO mode, the air conditioning
light
will turn on, and the recirculation and outside air
lights turn off. With the system in full auto control (both
the fan and mode knobs in AUTO), you still have the ability to override any function. However, continually
overriding the outside air or the A/C compressor will
limit the ability of the system
to cool the
vehicle quickly.
If
you push a button for a function which is not
available,
the light next to that button will flash three
times
to alert you that it’s not available.
To find your comfort zone, start with the
74°F (23°C)
setting and allow about 20 minutes for the system to
adjust the temperature
if necessary.
3-4

Downloaded from www.Manualslib.com manuals search engine 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 the floor
outlets.
As the interior temperature approaches a desired
setting, the blower speed will decrease. To maintain
interior comfort, the airflow will adjust between the
instrument panel air outlets and floor outlets. On bright
sunny days in cool weather, the airflow may come out of
the air conditioning and floor outlets (bi-level mode) to
maintain comfort and prevent stuffiness.
To avoid blowing cold air in cold weather, the system
will delay turning on the fan until warm air is available.
The length of delay depends on the outside air
temperature, engine coolant temperature or the time
since the engine was last started. As the coolant warms
up, the blower fan speed will gradually increase and air
will flow from the heater outlets, with some airflow to
the windshield to prevent fogging under most
normal conditions.
If your vehicle
is sitting out on a warm day and you
have the fan set
on AUTO, the air will first flow out of
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. Be careful
not to put anything over the solar sensor
located around the center of the instrument panel.
This sensor is used by the automatic system to
regulate temperature.
Mode Knob - Manual Operation
The right knob on the control panel allows you to
choose the direction of air delivery.
You can choose to set the climate control system
operations yourself, or let the system work for
you
by placing the system in AUTO mode. See “Mode
Knob
- Automatic Operation” earlier in this section.

system to use outside air. Press it again to close off the
outside air.
Pressing the OUTSIDE AIR button
will cancel the
RECIRCULATION button.
RECIRCULATION: Press this button to limit
the amount of fresh air entering your vehicle. This is
helpful when you are trying to limit odors entering your
vehicle. In the AUTO mode, the system
will use
recirculation as necessary
to cool the air. Pressing the
recirculation button
will change the operation to a
manual mode and the air will recirculate non-stop. Press
this button again to turn off the recirculation feature. RECIRCULATION may be selected
with the fan control
in OFF to limit odors, outside
air and dust from entering
your vehicle.
Pressing the RECIRCULATION button
will cancel the
OUTSIDE AIR button.
A/C: Press this button to turn the air conditioning
on and
off. The system will cool and dehumidify the air
inside the vehicle when the A/C light
is on.
Air conditioning
will be automatically disabled when
the outside temperature drops below a level which air
conditioning is ineffective.
Remember that
in order for the automatic system to perform
well,
it needs A/C to provide cooling performance.

Downloaded from www.Manualslib.com manuals search engine 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.
For quick cool-down on very hot days, use MAX A/C
with the temperature knob turned to the left. This setting
should be used to keep odors and/or dust from entering
the vehicle. For normal cooling
on hot days, use A/C
with the temperature knob turned to the left.
On vehicles equipped with the Electronic Climate
Control system, this same performance can be achieved
as long as the A/C is enabled and the outside air button
is not active.
Heating
On cool but sunny days, use BI-LEVEL A/C to deliver
warm air to the
floor and cooler air to the instrument
panel outlets.
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.
The heater works best if you keep your windows closed
while using it. On cold days,
use HEATER with the
temperature knob turned
to the right. BLEND is useful
in cool weather when
you have fog or ice on the
windshield or side windows.
If you use the optional engine coolant heater before starting your engine, your heating system will produce
warmer air faster to heat the passenger compartment in
cold weather. See “Engine Coolant Heater” in the Index.
Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use
VENT to direct outside air
through your vehicle. Airflow is through the instrument
panel outlets.
Your vehicle’s ventilation system supplies outside air to
the inside
of your vehicle when it is moving. When the
vehicle is
not moving, you can get outside air to flow
through by selecting any mode and any fan speed.

Downloaded from www.Manualslib.com manuals search engine You will find air outlets in the center and on the sides of
your instrument panel.
You can direct the airflow side-to-side by rotating the
thumbwheel located in the center of the vent. The vent
can be tilted
up and down also. To control the amount of
airflow through the outlets, rotate the thumbwheel
below the vent.
Ventilation Tips
Keep the hood and front air inlet free of ice, snow or
any other obstruction (such
as leaves). The heater
and defroster will work far better, reducing the
chance
of fogging the inside of your windows.
When you enter a vehicle in cold weather, move the
fan control to high for
a few moments before driving
off. This helps clear the intake ducts of snow and
moisture, and reduces the chance of fogging the
inside of your windows.
objects. This helps air to circulate throughout
your vehicle.
Keep the air path under the front seats clear of
Defogging and Defrosting
On cool, humid days, use BLEND to keep the
windshield and side windows clear.
Use DEFROST to remove fog or ice from the
windshield quickly in extreme humid or cold conditions.
Turn the temperature knob to the right and move the fan
control toward high.
