located on the climate
control panel.

2. Press the PASS button or the up or down arrows
on the passenger side to turn the passenger
temperature set on and off. When turned on, the
passenger temperature will be the same as
the driver setting. Press the up or down arrow on
passenger side to adjust the passenger temperature
setting.
When the passenger temperature set is off, the
passenger display will be off and the driver’s
set temperature will be for the driver and passenger.
In cold weather, the system will start at reduced
fan speeds to avoid blowing cold air into the vehicle
until warmer air is available. The system will start
out blowing air at the oor but may change
modes automatically as the vehicle warms up to
maintain the chosen temperature setting. The length
of time needed for warm up will depend on the
outside temperature and the length of time that has
elapsed since the vehicle was last driven.
3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then, adjust the temperature, if
necessary.
Do not cover the solar sensor located in the center
of the instrument panel, near the windshield. For
more information on the solar sensor, see “Sensors”
later in this section.4. Press OFF to turn the climate control system off.
Only the rear defog and heated seats will function.
Press AUTO or any other button except the
heated seats or rear defog to turn the climate
control system back on.
This control has 4 types of operation.
Automatic can set/change the temperature
only. AUTO and temperature only will appear
on the display.
Semi-Automatic Fan can set/change the
temperature and mode. The fan operates
automatically. The temperature and mode will
appear on the display.
Semi-Automatic Mode can set/change the
temperature and fan speed. The mode operates
automatically. The fan speed and temperature will
appear on the display.
Manual can set/change the temperature, mode and
fan. The fan speed, temperature and mode will
appear on the display.
If your vehicle has the remote start feature, the climate
control system will automatically regulate the inside
temperature of your vehicle when the remote start
system is activated. Normal operation and the last
setting of the climate control system will return after the
key is turned to the ON position.

Recirculation is not available while in the defrost or
oor/defog modes. Using recirculation for long periods of
time may cause the air inside your vehicle to become too
dry. To prevent this from happening, after the air in your
vehicle has cooled, turn the recirculation mode off.
#(Air Conditioning):Press this button to turn the
air conditioning compressor on and off. The indicator
light on the button will come on when the air
conditioning is on.
((Heated Seats):Press this button to turn the driver
or passenger heated seats on and off. SeeHeated
Seats on page 1-5for additional information.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control system is
used properly. There are two modes to clear fog or frost
from your windshield. Use the oor/defog mode to
clear the windows of fog or moisture and warm
the passengers. Use defrost to remove fog or frost from
the windshield more quickly.
-(Floor/Defog):Press this button to direct the air
between the windshield, oor outlets and side windows.
When you select this mode, the system turns
recirculation off and runs the air conditioning compressorunless the outside temperature is near or below
freezing. Pressing the recirculation button will have no
effect other than turning on the telltale light while in
oor/defog mode.
1(Defrost):Press this button to direct most of the
air to the windshield, with some air directed to the
side windows. In this mode, the system will automatically
turn off the recirculation and run the air conditioning
compressor, unless the outside temperature is near or
below freezing. Pressing the recirculation button will
have no effect other than turning on the telltale
light while in defrost mode.
Do not drive the vehicle until all windows are clear.
Sensors
The solar sensor on the vehicle monitors the solar heat
and the air inside of the vehicle. This information is
used to maintain the selected temperature by initiating
needed adjustments to the temperature, the fan
speed, and the air delivery system. The system may
also supply cooler air to the side of the vehicle facing the
sun. The recirculation mode will also be activated, as
necessary. Do not cover the solar sensor located in the
center of the instrument panel, near the windshield,
or the system will not work properly.
