The passenger’s temperature setting can be set
to
match the driver’s temperature setting by pressing and
holding the AUTO button for four seconds. Both the
driver and passenger arrows will be displayed.
Automatic Operation
AUTO (Automatic): When automatic operation is
active the system will control the inside temperature, the
air delivery, and the fan speed.
0 (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 floor. 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.
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 driver’s set temperature, delivery
mode and fan speed. Press the AUTO button again
within five seconds
to display the passenger’s set
temperature.
If the driver and passenger’s temperature settings
are not the same, the opposite side temperature
setting will be displayed for an additional five
seconds. To make the passenger’s temperature the
same as the driver’s press and hold the AUTO
button for approximately four 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 approximately
40°F
(4°C). The air inlet will normally be set to outside air.
If it’s 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
illuminate in recirculation.

2 (Panel): This setting will deliver air to the
instrument panel outlets.
+2 (Bi-Level): This setting will deliver warmer air to the
floor and cooler air
to the instrument panel outlets.
(Floor): This setting will deliver air to the floor
outlets.
+3 (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 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.
If you select recirculation while in defrost, defog or
floor, the light on the button will flash and go out
to let
you know this is not allowed. This is
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. Be sure
A/C off
is not selected. You will want to allow the air
conditioning
to run automatically to help dehumidify
the air.

If you press the MODE button to select an air delivery
mode, the display will change to show you the selected
air delivery mode. After ten seconds, the display will
change to show the driver 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 ten 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 five seconds,
the current passenger’s set temperature setting and
an arrow for five seconds and
0 the automatic air delivery mode and fan speed.
3-22

If the driver’s and passenger’s temperature settings are
the same when AUTO
is pressed, the temperature
setting and both arrows will be displayed for five
seconds along with the automatic air delivery mode and
fan speed. After the five second update, the display
will change to show the temperature setting, both arrows
and AUTO.
Air Conditioning
a (Air Conditioning): Press this button to turn the air
conditioning compressor on and
off.
% (Air Conditioning Off): When you turn the air
conditioning
off, this symbol will appear on the display.
When air conditioning is selected or in AUTO mode,
the system will run the air conditioning automatically to
cool and dehumidify the air entering the vehicle.
If
you select A/C off while in front defrost or defog, the
A/C off symbol will flash to let you know this is not
allowed. This is
to prevent fogging.
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for
your vehicle to cool down. Then keep your windows
closed for the air conditioner to work its best. On
cool, but sunny days while using manual operation
of the automatic system, use bi-level
to deliver warm
air to the floor and cooler air to the instrument
panel outlets. To warm or cool the air delivered, turn the
temperature knob to the desired setting.
In AUTO mode the system will cool and dehumidify the
air inside the vehicle. Also while in AUTO mode, the
system will maximize its performance by using
recirculation as necessary.
Heating
On cold days when using manual operation of the
automatic system, choose floor mode to deliver air to
the floor outlets. To warm or cool the air delivered, turn
the temperature knob to the desired setting.
If you want to use the automatic mode, press
AUTO and adjust the temperature by turning the
temperature knob.
The heater works best
if you keep the windows closed
while using it.

patterns. When the transmission fluid temperature
returns
to normal, the display will turn off and the
transmission shifting patterns will return
to normal.
Notice: If you keep driving your vehicle with the
transmission
TRANS FLUID HOT message
displayed, you can damage the transmission. This
could lead to costly repairs that may not be covered
under your warranty.
The following situations can cause the transmission to
operate at higher temperatures:
Towing a trailer
@ Hot outside air temperatures
Hauling a large or heavy load
Low transmission fluid level
High transmission fluid level
Restricted air flow to the radiator.
A temporary solution
to hotter transmission operating
temperatures may be
to let the transmission cool down.
If the transmission is operated at higher temperatures
on a frequent basis, see Scheduled Maintenance
on page 6-5 for the proper transmission maintenance
intervals.
TRANS HOT IDLE ENGINE
