Defogging and Defrosting
Fog on the inside of the vehicle is a result of high
humidity causing moisture to condense on the cool
window glass. This can be minimized if the climate
control system is used properly. There are
two modes to clear frost or fog from the windshield.
Use the defog mode to clear the windows of
condensation and to warm the vehicle’s occupants.
Use the defrost mode to remove frost or
condensation from the windshield quickly.
See “Rear Window Defogger” later in this section
for information on clearing the rear window of
fog or ice.
.(Floor/Defog):Use the oor/defog mode to
clear the windows of fog or moisture and to
warm the passengers. This mode directs the air
equally between the windshield and the oor
outlets, along with some directed to the side
window outlets.
This mode will automatically use outside air. The
air conditioning compressor will be engaged
unless the outside temperature is 40°F (4°C) or
below. Recirculation cannot be selected when
in this mode even though the indicator light comes
on when the recirculation button is pressed.
1(Defrost):Use the defrost mode to remove
fog or frost from the windshield more quickly. This
mode directs most of the air to the windshield
and the side window outlets, with some air directed
to the oor outlets. This mode has a timer and
will shut off after ve minutes.
This mode will automatically use outside air. The
air conditioning compressor will be engaged
unless the outside temperature is 40°F (4°C) or
below. Recirculation cannot be selected when
in this mode even though the indicator light comes
on when the recirculation button is pressed.
Temperature
The knob on the right of the climate control panel
is the temperature adjustment that can be used
with any of the climate control modes.
Turn the knob clockwise for warmer settings and
counterclockwise for colder settings.

Air Conditioning
#
(Air Conditioner):Press this button to turn
the air conditioning compressor on or off. An
indicator light to the right of the button will come
on. This button has no control over the air
conditioning compressor when in Floor/Defog and
Defrost modes. The instrument panel brightness
control may have to be adjusted to the highest
setting in order to see the indicator. See
Instrument Panel Brightness on page 147for
additional information.
On hot days during the vehicle’s initial start-up,
open the windows to let hot inside air escape; then
close them. This helps to reduce the time it
takes for the vehicle to cool down. It also helps
the system to operate more efficiently.
For quicker cool down on hot days, do the
following:
1. Select any mode setting between vent and
the setting before defrost.
2. Select the air conditioner.
3. Select the coolest temperature.
4. Select the highest climate control fan speed.Using these settings will set recirculation for quicker
cool down (the light indicator will not turn on).
If outside air is desired, press the recirculation
button twice.
Using these settings together for long periods of
time may cause the air inside the vehicle to
become too dry. To prevent this from happening,
after ve minutes the recirculation door will
open slightly to allow some outside air into the
vehicle.
The air conditioning system removes moisture
from the air, so sometimes there may be a small
amount of water dripping underneath the
vehicle while it is idling or after the engine is
turned off. This is normal.
Recirculation
h
(Recirculation):Press this button to
activate the recirculation mode. With this selection,
inside air is recirculated into the vehicle. This
mode reduces outside air and odors from entering
the vehicle. It may also help to heat or cool the
air inside the vehicle more quickly.
