Climate Controls
Dual Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
Automatic Operation
AUTO (Automatic):When this button is pressed and
the temperature is set, the system will automatically
control the inside temperature, the air delivery mode,
the air conditioning compressor and the fan speed.
AUTO will appear on the display.1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting
between 70°F (21°C) and 80°F (27°C).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool any
faster. If you set the system at the warmest
temperature setting, the system will remain in
manual mode at that temperature and it will not go
into automatic mode.
In cold weather, the system will start at reduced fan
speeds to avoid blowing cold air into your vehicle
until warmer air is available. The system will
start out blowing air at the oor but may change
modes automatically as the vehicle warms up
to maintain the chosen temperature setting.
The length of time needed for warm up will depend
on the outside temperature and the length of
time that has elapsed since your vehicle was last
driven.
3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature,
if necessary.

You can switch from English to metric units through the
Driver Information Center (DIC). If you have the Base
audio system, seeDIC Main Menu on page 3-60.Ifyou
have the Navigation system, see “Setup Menu” in the
Index of the Entertainment and Navigation System
Supplement.
The air-conditioning system removes moisture from the
air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling
or after turning off the engine. This is normal.
Do not cover the solar sensor located in the center of
the instrument panel, near the windshield. For more
information on the solar sensor, see “Sensors” later in
this section.
Manual Operation
yNz(Mode):Pressing the MODE switch and
changing the mode cancels automatic operation
and places the system in manual mode. Press AUTO to
return to automatic operation.
The outboard air outlets will always receive airow
regardless of the mode selected. SeeOutlet Adjustment
on page 3-31to change this airow from the outboard
outlets.To change the current mode, select one of the following:
Y(Vent):This mode directs air to the instrument
panel outlets.
\(Bi-Level):This mode directs approximately half of
the air to the instrument panel outlets, and then
directs most of the remaining air to the oor outlets.
Some air may be directed toward the windshield.
In automatic operation, cooler air is directed to the upper
outlets and warmer air to the oor outlets.
[(Floor):This mode directs most of the air to the
oor outlets with some air directed to the outboard
outlets (for the side windows), and a little air directed to
the windshield.
The MODE switch can also be used to select the defog
mode. Information on defogging and defrosting can
be found later in this section.
3-27

yAz(Fan):Press this switch to increase or
decrease the fan speed. Pressing this switch cancels
automatic operation and places the system in manual
mode. Press AUTO to return to automatic operation.
If the airow seems low when the fan speed is at
the highest setting, the passenger compartment air lter
may need to be replaced. For more information, see
Passenger Compartment Air Filter on page 3-34
andScheduled Maintenance on page 6-4.
h(Recirculation):This mode keeps outside air
from coming in the vehicle. It can be used to prevent
outside air and odors from entering your vehicle or
to help heat or cool the air inside your vehicle more
quickly. Press this button to turn the recirculation mode
on or off. The air-conditioning compressor also
comes on.
Recirculation is not available in the defrost mode and
will automatically turn off after 10 minutes when
defog is selected.Using recirculation for long periods of time may cause
the air inside your vehicle to become too dry or
stuffy. To prevent this from happening, after the air in
your vehicle has cooled, turn the recirculation mode off.
QPWRR(Power/Driver’s Temperature):Press
the PWR button located on the driver’s side of the
climate control panel to turn the entire climate control
system on or off. Press the up or down arrow on
the switch to increase or decrease the temperature
inside your vehicle.
QPWRR(Power/Passenger’s Temperature):Press
the PWR button located on the passenger’s side of
the climate control panel to turn the passenger’s climate
control system on. Press the up or down arrow on
the switch to increase or decrease the temperature for
the front passenger.
A/C OFF (Air Conditioning):Press this button to
manually turn off the air conditioning compressor.
Press AUTO to return to automatic operation or press
the A/C OFF button again.
3-28

Defogging and Defrosting
Fog on the inside of 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 clear fog
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.
yNz(Mode):Press this button until defog appears
on the display.
-(Defog):This mode directs the air between the
windshield, oor outlets and side windows. When you
select this mode, the system turns off recirculation
and runs the air-conditioning compressor unless
the outside temperature is at or below freezing.
The recirculation mode is cancelled when you enter
defog mode. If you select recirculation while in defog
mode, it will be cancelled after 10 minutes.If you have fogging on the side windows, turn the
thumbwheel on the outboard outlets to the side window
defog position. SeeOutlet Adjustment on page 3-31
for more information.
0(Defrost):Pressing defrost directs most of the air
to the windshield, with some air directed to the side
windows. In this mode, the system will automatically
turn off recirculation and run the air-conditioning
compressor, unless the outside temperature is at or
below freezing. Recirculation cannot be selected while
in the defrost mode.
This mode may also cause the fan speed and air
temperature to increase.
If you have fogging on the side windows, turn the
thumbwheel on the outboard outlets to the side window
defog position. SeeOutlet Adjustment on page 3-31
for more information. Do not drive the vehicle until all the
windows are clear.
