Certain power accessory plugs may not be
compatible to the accessory power outlet and

If you experience a problem, see your dealer for
additional information on the accessory power
plugs.
Notice:Adding any electrical equipment to
your vehicle may damage it or keep other
components from working as they should.
The repairs would not be covered by your
warranty. Do not use equipment exceeding
maximum amperage rating of 20 amperes.
Check with your dealer before adding electrical
equipment.
When adding electrical equipment, be sure to
follow the proper installation instructions included
with the equipment.
Notice:Improper use of the power outlet can
cause damage not covered by your warranty.

Mode Control
To change the current mode, select one of the
following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs half of the air to
the instrument panel outlets; then directs most
of the remaining air to the oor outlets. A little air
is directed toward the windshield and the side
window outlets. Cooler air is directed to the upper
outlets and warmer air to the oor outlets.
6(Floor):This mode directs most of the air to
the oor outlets with a little air directed to the
windshield and the side window outlets.
h(Recirculation):The recirculation mode is
used to recirculate the air inside of your vehicle.
Use this mode to help prevent outside odors
and/or dust from entering your vehicle or to help
cool the air inside of your vehicle more quickly.
Press this button to turn the recirculation mode on
or off. The light on the recirculation button will
illuminate. Recirculation cannot be used in oor,
defog or defrost modes. An indicator on the button
will light up, ash three times and turn off when
recirculation is selected in these modes. The
air-conditioning compressor will also come on when
this mode is activated. While in recirculation mode
the windows may fog when the weather is cold and
damp. To clear the fog, select either the defog or
defrost mode and increase fan speed.

Temperature Control
Driver’s Side:The lever on the left side of the
climate control panel is used to raise or lower the
temperature on the driver’s side of the vehicle.
This lever also adjusts the temperature to
the center console outlets, if the vehicle has them.
Passenger’s Side:The lever on the right side
of the climate control panel is used to raise
or lower the temperature on the passenger’s side
of the vehicle.
#(Air Conditioning):Press this button to turn
the air-conditioning system on or off. When
the button is pressed, an indicator light will come
on and the system will begin to cool and
dehumidify the air inside of your vehicle. You may
notice a slight change in engine performance
when the air conditioning compressor shuts off and
turns on again. This is normal.
Defogging and Defrosting
Fog on the inside of the 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 choose from to clear fog or frost
from your windshield. Use the defog mode to clear
the windows of fog or moisture and warm the
passengers. Use the defrost mode to remove fog
or frost from the windshield more quickly.
Turn the right knob to select one of the following
modes:
-(Defog):This mode directs the air to the oor
outlets, windshield and the side window outlets.
The air conditioning compressor will run
automatically to dehumidify the air to prevent
window fogging. The recirculation mode cannot be
selected while in the defog mode.
233

1(Defrost):This mode directs most of the air to
the windshield and the side window outlets, with
only a little air directed to the oor outlets. The air
conditioning compressor will run automatically
to dehumidify the air to prevent window fogging.
The recirculation mode cannot be selected while in
defrost mode.
Do not drive the vehicle until all the windows are
clear.
Rear Window Defogger
If your vehicle has this feature, the rear window
defogger uses a warming grid to remove fog from
the rear window.
If your vehicle has a sliding rear window, you will
not have a rear window defogger.
<(Rear):Press this button to turn the rear
window defogger on or off. An indicator light in the
button will come on to let you know that the
rear window defogger is activated. This button will
also activate the heated mirrors, if the vehicle

off several minutes after the button is pressed.
Pressing the button while the defogger is running
can also turn off the defogger.
W(Mirror):If your vehicle does not have a rear
defogger and has heated mirrors, your vehicle
will have this button to activate the heated mirrors.
Notice:Do not use anything sharp on the
inside of the rear window. If you do, you could
cut or damage the warming grid, and the
repairs would not be covered by your warranty.
Do not attach a temporary vehicle license,
tape, a decal or anything similar to the
defogger grid.
234

When AUTO is selected, the air conditioning
operation and air inlet will be automatically
controlled. The air conditioning compressor will
run when the outside temperature is over
about 40°F (4°C). The air inlet will normally be
set to outside air. If it is hot outside, the air
inlet may automatically switch to recirculate
inside air to help quickly cool down your
vehicle. The light on the button will come on in
recirculation.
2. Set the driver’s and passenger’s temperature.
To nd your comfort setting, start with a 74°F
(23°C) temperature setting and allow about
20 minutes for the system to regulate. Turn the
driver’s or passenger’s side temperature
knob to adjust the temperature setting as
necessary. If you choose the temperature
setting of 60°F (15°C) the system will remain
at the maximum cooling setting. If you
choose the temperature setting of 90°F (32°C)
the system will remain at the maximum
heat setting. Choosing either maximum setting
will not cause the vehicle to heat or cool
any faster.Be careful not to cover the solar sensor
located on the top of the instrument panel
near the windshield. This sensor regulates air
temperature based on sun intensity. It also
turns on the headlamps. For more information
on the solar sensor, see “Sensors” later in
this section.
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 engine coolant temperature.
Pressing the fan switch will override this delay
and change the fan to a selected speed.
9(Off):Press this button to turn off the entire
climate control system. Outside air will still
enter the vehicle, and will be directed to the oor.
This direction can be changed by pressing the
mode button. The temperature can also be
adjusted using either temperature knob. Press the
up or down arrows on the fan switch, the defrost
button, the AUTO button, or the air conditioning
button to turn the system on when it is off.
