compressor. The indicator light above the button will
glow when the button is pressed. ,You don't have to press

it will already be running in these modes.
Air Conditioning
On very hot days, open the windows long enough to let
hot, inside air escape. This reduces the time for the
vehicle
to cool down.
For quick cool-down on very hot days, use
MAX with
the temperature knob all the way in the blue area.
If this
setting is used
for long periods of time, the air in your
vehicle may become too dry.
For normal cooling on hot days, use UPPER with the
temperature knob in the blue area and the
A/C button
pushed in. The system will bring in outside
air and cool it.
On cool, but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
You can use BI-LEVEL with the temperature knob in
the middle and the A/C button pushed in. The system
will bring in outside air and direct it to your upper body,
while sending slightly warmed air to your lower body.
You may notice this temperature difference more at
some times than others.

Automatic Control Dual Zone Button Light
For the most efficient operation, you should set the
system temperature and press AUTO. The system will
select the best fan speed and airflow settings to keep you
comfortable. The air conditioning compressor will run if
the outside temperature is above
38 OF (3.3 O C). You may
notice a delay of three to four minutes before the fan
comes on.
Driver's Temperature Knob
The left knob sets the temperature for the entire system
when the light on DUAL button isn't lit.
If the light is
lit, the knob sets the temperature for the driver. Turn the
knob toward red (clockwise) to raise the desired cabin
temperature. Turn it toward blue (counterclockwise) to
lower the temperature. The display will show your
selection for a few seconds, then the outside temperature
will show or be displayed.
Passenger's Temperature Knob
The right knob sets the desired cabin temperature for the
passenger and will automatically force the system into a
dual zone operation, lighting the dual zone button light.
Turn the right knob toward red (clockwise) to raise the
temperature. Turn it toward blue (counterclockwise) to
lower the temperature. The
dual zone button light indicates whether the system
is in single zone
or dual zone operation. When there is
no desire for dual zone operation, push the lit dual zone
button to return to single zone operation. The dual zone
button light will
go off.
The system will operate to achieve your comfort set
point as quick as possible. If you set the temperature for
60°F (16°C)
or 90°F (32"C), the fan will go to it's
highest speed, unless you manually select a lower speed.
The system will maintain full cold or full hot operation
at these settings.
Cold Weather Example: (When you start the vehicle in
cold weather, below freezing or after being parked
overnight). If your Driver Set Temperature is 73°F
(23 "C) and you are in Full Automatic mode, the system
will automatically move the temperature doors to full
hot. The blower will start out at a low speed and the
blower speed will increase
as the engine warms up. The
air will be delivered to the floor. As the interior of the
vehicle warms up to your desired comfort point, the
blower will decrease and
the temperature door will
move to a cooler position to maintain your desired
comfort. As the cabin warms
up or the sun load
increases, the system could switch to air delivered
to the windshield and the floor. (Defog mode)
