Fog Lamps
If your vehicle has fog lamps, use them for better vision
in foggy or misty conditions.
The fog lamp button is
located on the left side of
the instrument panel.
Your parking lamps and/or low-beam headlamps must
be on for your fog lamps to work.Press the button to turn the fog lamps on. Press the
button again to turn them off. An indicator light will glow
in the button when the fog lamps are on.
Remember, fog lamps alone will not give off as much
light as your headlamps. Never use your fog lamps
in the dark without turning on your headlamps.
The fog lamps will go off whenever your high-beam
headlamps come on. When the high beams go off, the
fog lamps will come on again.
The fog lamps will be cancelled after the ignition is
turned off. If you still want to use the fog lamps after
you restart the vehicle, you will need to press the
fog lamp button again.
Some localities have laws that require the headlamps to
be on along with the fog lamps.

Dual Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
Turn the knob to the off position to turn off the fan.
If the knob is in off outside air will still enter the vehicle,
and will be directed based on the position of the
mode knob. The temperature can also be adjusted
using the temperature levers.
Turn the right knob clockwise or counterclockwise to
direct the airow inside of your vehicle.To change the current mode, select one of the following:
H(Vent):This mode directs air to the instrument
panel vents.
)(Bi-Level):This mode directs half of the air to
the instrument panel vents; then directs most of the
remaining air to the oor vents. A little air is directed
toward the windshield and the side window vents.
Cooler air is directed to the upper vents and warmer
air to the oor vents.
6(Floor):This mode directs most of the air to the
oor vents with a little air directed to the windshield and
the side window vents.
@(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.
3-23

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 equipped).
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 vents.
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.
1(Defrost):This mode directs most of the air to the
windshield and the side window vents, with only a
little air directed to the oor vents. 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.
3-24

Rear Window Defogger
The lines you see on the rear window warm the glass.
The rear window defogger uses a warming grid to
remove fog from the rear window.
<(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.
The rear window defogger will automatically turn off
several minutes after the button is pressed. Pressing the
button while the defogger is running can also turn off
the defogger.
If your vehicle is equipped with heated mirrors this
button will activate them.
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.
Dual Automatic Climate Control
System
With this system, you can control the heating, cooling
and ventilation in your vehicle. Your vehicle also has
a ow-through ventilation system described later in this
section.
You can select different climate control settings for the
driver and passengers.

speed.
w9x(Fan):The switch with the fan symbol allows
you to manually adjust the fan speed. Press the up arrow
to increase fan speed and the down arrow to decrease
fan speed.
Pressing this button when the system is off will turn the
system on.

display will go blank after displaying the current status of
the system.
H(Panel):This setting will deliver air to the
instrument panel outlets.
)(Bi-Level):This setting will deliver warmer air to the
oor and cooler air to the instrument panel outlets.

outlets.
-(Defog):See “Defogging and Defrosting” later in
this section.
@(Recirculation):Press this button to limit the
amount of outside air entering your vehicle. The light on
the recirculation button will glow. This is helpful when you
are trying to limit odors entering your vehicle and for
maximum air conditioning performance in hot weather.
Press this button again to allow outside air to enter the
vehicle. The light on the recirculation button will go off.
Pressing this button also cancels the auto recirculation
feature. To resume the auto recirculation function, press
the AUTO button. Each time the vehicle is started, the
system will revert to the auto recirculation function.
3-28

If you select recirculation while in defrost, defog or oor,
the light in the button will ash and then go out to let you
know that this is not allowed. This is normal and helps to
prevent fogging.
When the weather is cool or damp, operating the system
in recirculation for extended periods of time may cause
fogging of the vehicle’s windows. To clear the fog, select
either defog or front defrost.
You may also notice that the A/C compressor will run
while in recirculation mode. This is normal and helps to
prevent fogging.
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.

mode, the display will change to show you the selected
air delivery mode. After 10 seconds, the display will
change to show the driver’s temperature setting and the
selected mode.
If you press the up or down arrows on the fan switch,
the display will change to show the selected fan speed.
After 10 seconds, the display will change to show the
driver temperature setting and the selected mode.
Whenever you press AUTO, the display will change to
show the following:
The current driver’s set temperature and an arrow
for ve seconds
