top of the instrument panel near the
windshield or the sensor grille below
the climate control faceplate. These
two sensors help regulate the inside
air temperature.
AUTO (Automatic Fan):
Turn the
fan knob to AUTO for the system to
automatically adjust the fan speed
to reach the desired inside
temperature.

8-6 Climate Controls
AUTO (Automatic Air Delivery
Mode):Turn the air delivery mode
knob to AUTO for the system to
automatically control the direction of
the airflow to help reach the desired
inside temperature.
The system automatically controls
the air inlet to supply the outside air
or recirculated inside air needed to
heat or cool the vehicle faster. The
recirculation button indicator light is
lit whenever the recirculation mode
is on.
Press the outside air button to
change to outside air. However, the
recirculation mode may turn back on
automatically.
In cold weather, if the fan and air
delivery modes are in automatic, the
system starts at lower fan speeds to
avoid directing cold air into the
vehicle until warmer air is available. The climate control system
directs air to the floor, but may
automatically change modes as the
vehicle warms up to maintain the
chosen temperature setting. The
length of time needed to warm the
interior depends on the outside
temperature and inside temperature
of the vehicle.
Manual Operation
A
(Fan Control): Turn clockwise or
counterclockwise to increase or
decrease the fan speed. To turn the
fan off, turn the left knob to the
9
position. In any setting other than
off, the fan runs continuously with
the ignition on. The fan must be
turned on to run the air conditioning
compressor. There will be some
airflow noticeable from the various
outlets when driving, even with the
fan in the off position. To turn off the
air completely, turn the fan to
9
and select the recirculation button. Temperature Control:
Turn
clockwise or counterclockwise to
increase or decrease the
temperature. Select the desired
cabin air temperature between
60‐90°F (16‐32°C). Typically, the
best setting is near 75°F (23°C).
Choosing the coldest or warmest
temperature setting does not cause
the system to heat or cool any
faster.
Air Delivery Mode Control: Turn
clockwise or counterclockwise to
change the current airflow mode.
Select from the following air delivery
modes:
H (Vent): Air is directed to the
instrument panel outlets.
) (Bi-Level): Air is divided
between the instrument panel
outlets and the floor outlets.
6 (Floor): Air is directed to the
floor outlets with some air directed
to the windshield.

Climate Controls 8-7
When this mode is selected, the
system turns the recirculation mode
off. Recirculation mode cannot be
selected while in floor mode. This is
to help prevent window fogging.
-(Defog):Clears the windows of
fog or moisture. Air is directed to the
floor outlets, with some air directed
to the windshield and side window
outlets. In this mode, the system
turns the recirculation mode off and
runs the air conditioning compressor
unless the outside air is at or below
freezing. Recirculation mode cannot
be selected while in defog mode.
This helps prevent window fogging.
0(Defrost): Removes fog or frost
from the windshield more quickly.
Air is directed to the windshield and
the side window outlets. In this
mode, the system turns the
recirculation mode off automatically
and runs the air conditioning
compressor unless the outside air is
at or below freezing. Recirculation
mode cannot be selected while in
defrost mode. This helps prevent
window fogging. For best results, clear all snow and
ice from the windshield before
defrosting.
#(Air Conditioning):
Press to turn
the air conditioning system on or off.
An indicator light comes on to show
that the air conditioning is on. The
air conditioning can be selected in
any mode as long as the fan is on
and the outside temperature is
above freezing. A flashing indicator
light indicates that the air
conditioning compressor is currently
not available.
On hot days, use the automatic fan
and automatic air delivery mode
settings and the vehicle will reach
the desired temperature more
quickly. The desired fan and air
delivery mode settings can still be
adjusted manually. Open the
windows to let the hot inside air
escape, then close them. This helps
reduce the time it takes for the
vehicle to cool down and helps the
system to operate more efficiently. The air conditioning system
removes moisture from the air, so a
small amount of water might drip
under the vehicle while idling or
after turning off the engine.
;(Outside Air):
Press to turn the
outside air mode on. An indicator
light comes on to show that outside
air is on. Air from outside the vehicle
will circulate throughout the vehicle.
The outside air mode can be used
with all modes, but it cannot be
used with the recirculation mode.
Pressing this button will cancel the
recirculation mode.

@(Recirculation): Press to turn
on the recirculation mode. An
indicator light comes on to show
that recirculation is on. This mode
recirculates and helps to quickly
cool or heat the air inside the
vehicle. It can be used to prevent
outside air and odors from entering
the vehicle. Avoid using the
recirculation mode during high
periods of humidity and cool outside
temperatures since this may result
in increased window fogging.
If window fogging is experienced,
select the defrost mode.
Recirculation mode is not available
in floor, defog or defrost modes and
will shut off automatically and
change to outside air. If the button is
selected in any of these modes, the
indicator will flash. This helps
prevent window fogging and
moisture building up inside the
vehicle.Rear Window Defogger

{WARNING
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
carbon monoxide (CO) which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle is stuck in the snow:
.Clear away snow from around
the base of your vehicle,
especially any that is blocking
the exhaust pipe.
.Check again from time to
time to be sure snow does
not collect there.
.Open a window about 5 cm
(two inches) on the side of
the vehicle that is away from
the wind to bring in fresh air.(Continued)
WARNING (Continued)
.Fully open the air outlets on
or under the instrument
panel.
.Adjust the Climate Control
system to a setting that
circulates the air inside the
vehicle and set the fan speed
to the highest setting. See
Climate Control System in the
Index.
For more information about
carbon monoxide, see Engine
Exhaust on page 9‑34.
Snow can trap exhaust gases
under your vehicle. This can
cause deadly CO (carbon
monoxide) gas to get inside. CO
could overcome you and kill you.

WARNING (Continued)
around the base of your vehicle,
especially any that is blocking the
exhaust.
Run the engine for short periods
only as needed to keep warm, but
be careful.
To save fuel, run the engine for only
short periods as needed to warm
the vehicle and then shut the engine
off and close the window most of
the way to save heat. Repeat this
until help arrives but only when you
feel really uncomfortable from the
cold. Moving about to keep warm
also helps.
If it takes some time for help to
arrive, now and then when you run
the engine, push the accelerator
pedal slightly so the engine runs
faster than the idle speed. This
keeps the battery charged to restart
the vehicle and to signal for help
with the headlamps. Do this as little
as possible to save fuel.
