Automatic Operation
AUTO (Automatic):When automatic operation is
active the system will control the inside temperature, the
air delivery, and the fan speed.
Use the steps below to place the entire system in
automatic mode:
1. Press the AUTO button.
When AUTO is selected, the display will change to
show the current temperature(s) and AUTO will
be lit on the display. The current delivery mode and
fan speed will also be displayed for approximately
5 seconds.
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 the vehicle. The light on the
button comes on in recirculation.
3-24

6(Floor):Air is directed to the oor outlets, with
some to the windshield, side window outlets, and second
row oor outlets. In this mode, the system automatically
selects outside air.
-(Defog):This mode clears the windows of fog or
moisture. Air is directed to the windshield, oor outlets,
and side window vents. In this mode, the system
turns off recirculation and runs the air conditioning
compressor unless the outside temperature is close to
freezing. The recirculation mode cannot be selected
while in the defrost mode.
0(Defrost):This mode removes fog or frost from the
windshield more quickly. Air is directed to the
windshield and side window vents, with some directed
to the oor vents. In this mode, the system automatically
forces outside air into the vehicle and runs the air
conditioning compressor unless the outside temperature
is close to freezing. The recirculation mode cannot be
selected while in the defrost mode.
Do not drive the vehicle until all the windows are clear.
#(Air Conditioning):Press to turn the air conditioning
(A/C) compressor on and off. An indicator light comes on
to show that the air conditioning is on.If this button is pressed when the air conditioning
compressor is unavailable, the indicator ashes three
times and then turns off. If the air conditioning is on and
the outside temperature drops below a temperature
which is too cool for air conditioning to be effective, the air
conditioning light turns off to show that the air
conditioning mode has been canceled.
On hot days, open the windows long enough to let hot
inside air escape. This helps to reduce the time it takes
for the vehicle to cool down. It also 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. This is
normal.
@(Recirculation):Press to turn the recirculation
mode on. An indicator light comes on to show that the
recirculation is on.
This mode recirculates and helps to quickly cool the air
inside the vehicle. It can be used to help prevent
outside air and odors from entering the vehicle.

Outlet Adjustment
Your vehicle has air outlets located in the center and on
the side of your instrument panel that allow you to adjust
the direction and amount of airow inside the vehicle.
Move the louvers up or down. Use the thumbwheel next
to or underneath the outlet to close the louvers. For the
most efficient airow and temperature control, keep the
outlet in the fully opened position.
Operation Tips

Keep the hood and front air inlets free of ice, snow,
or any other obstruction, such as leaves. The
heater and defroster will work far better, reducing
the chance of fogging the inside of your windows.
Keep the air path under the front seats clear of
objects. This helps air to circulate throughout your
vehicle.
Adding outside equipment to the front of your vehicle,
such as hood-air deectors, etc., may affect the
performance of the heating and air conditioning
system. Check with your dealer before adding
equipment to the outside of your vehicle.
Warning Lights, Gages, and
Indicators
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
the warning lights and gages could prevent injury.
Warning lights come on when there may be or is a
problem with one of the vehicle’s functions. Some
warning lights come on briey when the engine is started
to indicate they are working.
Gages can indicate when there may be or is a problem
with one of the vehicle’s functions. Often gages and
warning lights work together to indicate a problem with
the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gages shows there
may be a problem, check the section that explains what
to do. Follow this manual’s advice. Waiting to do
repairs can be costly and even dangerous.
