Manual Operation
The air delivery mode or fan speed can be manually
adjusted using these buttons:
DC(Fan):Use the fan buttons to manually adjust the
fan speed. To increase or decrease the airow,
press the
DorCbutton.
Pressing one of these buttons when the system is off
will turn the system on. Pressing one of these buttons
when in automatic control will place the fan under
manual control. The fan setting remains displayed,
AUTO is no longer displayed, and the AUTO button
indicator light turns off. The air delivery mode will
remain under automatic control.
HG(Mode):Use the mode buttons to manually
change the direction of the airow in the vehicle.
Repeatedly press the
HorGbutton until the desired
mode appears on the display. Pressing one of these
buttons when the system is off will change air delivery
mode without turning the system on. Pressing one
of these buttons when in automatic control will place
the mode under manual control.
The air delivery mode setting remains displayed,
AUTO is no longer displayed, and the AUTO button
indicator light turns off.
H(Vent):This setting will deliver air to the instrument
panel outlets.
)(Bi-Level):This mode directs half of the air to
the instrument panel outlets and the oor outlets.
The ow can be divided between vent and oor outlets
depending upon where the knob is placed between
the settings. A little air is directed towards the windshield
and side window outlets. Cooler air is directed to the
upper outlets and warmer air to the oor outlets.
6(Floor):This mode directs most of the air to the oor
outlets, with some of the air directed to the windshield,
side window outlets, and second row oor outlets. In this
mode, the system automatically selects outside air.
-(Defog):See “Defogging and Defrosting” later in
this section.
@(Recirculation):Press this button to turn the
recirculation mode on. When the button is pressed,
an indicator light will come on.
This mode keeps outside air from entering the vehicle.
It can be used to reduce outside air and prevent
odors from entering the vehicle. Recirculation may also
help cool the air inside the vehicle more quickly once
the temperature inside the vehicle is less than the
outside temperature.

The recirculation mode cannot be used with oor,
defrost, or defogging modes. If you try to select
recirculation in one of those modes, the indicator will
ash three times and turn off. The air conditioning
compressor will also come on when this mode is
activated. While in recirculation mode the windows
may fog when the weather is cold and damp.
To clear the fog, select either the defog or defrost
mode and increase the fan speed. Recirculation
mode can be turned off by pressing the button again,
or turning off the engine.
AUX:For vehicles with the rear heat and air
conditioning controls. Press the AUX button to turn
the rear climate control system on or off. SeeRear
Air Conditioning and Heating System and Electronic
Climate Controls on page 3-29.
;(Outside Air, If Equipped):Press this button
to turn on the outside air mode. When this mode
is selected, air from outside the vehicle circulates
throughout the vehicle. An indicator light on the button
comes on to show that it is activated. The outside
air mode can be used with all modes, but it cannot
be used with the recirculation mode.
Air Conditioning
#
(Air Conditioning):Press this button to turn the
air conditioning (A/C) compressor on and off. When air
conditioning is selected, an indicator light comes on
to show that the air conditioning has been activated.
Pressing this button when the outside temperature is
too cool for air conditioning will make the air conditioning
indicator ash three times and then turn off to let you
know the air conditioning mode is not available. 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 your 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 underneath
the vehicle while idling or after turning off the engine.
This is normal.

Outlet Adjustment
Your vehicle has air outlets that let you adjust the
direction and amount of airow inside the vehicle.
Use the thumbwheels located beside the air outlets to
direct the airow up and down. Use the thumbwheels
below the air outlets to direct the air left or right.
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
the windows.
Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
the vehicle.
Adding outside equipment to the front of the
vehicle, such as hood-air deectors, etc., may affect
the performance of the heating and air conditioning
system. Check with your dealer/retailer before
adding equipment to the outside of your vehicle.
Rear Air Conditioning and
Heating System and Electronic
Climate Controls
If your vehicle has this rear climate control system
there are rear seat audio controls located in the
center console.
The rear system can be controlled through the AUX
button on the front climate control panel. Press the
AUX button to turn the rear climate control system
on or off. An indicator light in the AUX button comes
on when the rear climate control system is on. The
direction, temperature, and speed of the airow for
the rear of the vehicle will be the same as those set
for the front of the vehicle.
Use the controls located in the rear of the front console,
to independently control the air ow for the rear of
the vehicle separately from that of the front of the
vehicle. To turn the system on, press any of the rear
air conditioning control buttons, except the
Cbutton.
To turn the system off, press and hold the
Cbutton.

Appearance Care
Interior Cleaning
Your vehicle’s interior will continue to look its best if it is
cleaned often. Although not always visible, dust and
dirt can accumulate on your upholstery. Dirt can damage
carpet, fabric, leather, and plastic surfaces. Regular
vacuuming is recommended to remove particles
from your upholstery. It is important to keep your
upholstery from becoming and remaining heavily soiled.
Soils should be removed as quickly as possible. Your
vehicle’s interior may experience extremes of heat
that could cause stains to set rapidly.
Lighter colored interiors may require more frequent
cleaning. Use care because newspapers and garments
that transfer color to your home furnishings may also
transfer color to your vehicle’s interior.
When cleaning your vehicle’s interior, only use cleaners
specically designed for the surfaces being cleaned.
Permanent damage may result from using cleaners
on surfaces for which they were not intended.Use glass cleaner only on glass. Remove any accidental
over-spray from other surfaces immediately. To prevent
over-spray, apply cleaner directly to the cleaning cloth.
Notice:If you use abrasive cleaners when cleaning
glass surfaces on your vehicle, you could scratch
the glass and/or cause damage to the rear window
defogger. When cleaning the glass on your
vehicle, use only a soft cloth and glass cleaner.
Many cleaners contain solvents that may become
concentrated in your vehicle’s breathing space.
Before using cleaners, read and adhere to all safety
instructions on the label. While cleaning your vehicle’s
interior, maintain adequate ventilation by opening
your vehicle’s doors and windows.
Dust may be removed from small buttons and knobs
using a small brush with soft bristles.
Your dealer/retailer has a product for cleaning your
vehicle’s glass. Should it become necessary, you can
also obtain a product from your dealer/retailer to remove
odors from your vehicle’s upholstery.
