the way counterclockwise to turn the front system off.
Air Delivery Mode Control : Turn clockwise or
counterclockwise to change the direction of the airflow
inside the vehicle. The knob can be positioned between
two modes to select a combination of those modes.
Select from the following:
H (Vent) : Air is directed to the instrument panel outlets.
) (Bi-Level) : Air is divided between the instrument
panel and floor outlets.
6 (Floor) : Air is directed to the floor outlets, with some
air directed to the windshield and side window outlets.
In this mode, the system automatically selects outside
air. Recirculation cannot be selected in floor mode.
- (Defog) : This mode clears the windows of fog or
moisture. Air is directed to the windshield, floor outlets,
and side window vents. 0
(Defrost) : This mode removes fog or frost from the
windshield more quickly. Air is directed to the
windshield and the side window vents, with some air
directed to the floor vents. The system automatically
forces outside air into the vehicle.
The recirculation mode cannot be selected in the defog
or defrost mode. When either mode is selected, the
system runs the air conditioning compressor, unless the
outside temperature is close to freezing.
Do not drive the vehicle until all the windows are clear.
:(Outside Air): Press to turn the outside air mode
on. An indicator light comes on to show that outside air
is on. In this mode outside air circulates throughout the

?(Recirculation):Press to turn the recirculation
mode on. An indicator light comes on to show that
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.
The recirculation mode cannot be used with floor, defog
or defrost modes. If recirculation is selected with one of
these modes, the indicator light flashes three times and
then turns off. 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.
The recirculation mode can be turned off by pressing
the outside air button, or by turning off the ignition.
# (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 switch is on.
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.Rear Window Defogger
For vehicles with a rear window defogger, a warming
grid is used to remove fog from the rear window.
< (Rear) : Press to turn the rear window defogger on
or off. An indicator light on the button comes on to show
that the rear window defogger is on.
The rear window defogger only works when the ignition
is in ON/RUN. The rear window defogger stays on for
approximately 10 minutes after the button is pressed,
unless the ignition is turned to ACC/ACCESSORY or
LOCK/OFF. The defogger can also be turned off by
turning off the engine.
Notice: Do not use anything sharp on the inside of
the rear window. If you do, you could cut or damage
the warming grid, and the repairs would not be
covered by the vehicle warranty. Do not attach a
temporary vehicle license, tape, a decal or anything
similar to the defogger grid.

6(Floor):Air is directed to the floor outlets, with some
to the windshield, side window outlets, and second row
floor 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, floor 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 floor 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.
The passenger temperature control cannot be activated
while in defrost mode. If the PASS button is pressed,
the button indicator flashes three times and will not
work. If the passenger temperature buttons are
adjusted, the driver temperature indicator changes. The
passenger temperature will not be displayed. If vent, bi-level, or floor mode is selected again, the
climate control system displays the previous
temperature settings.
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 due to outside conditions, the
indicator flashes 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.
The recirculation mode cannot be used with floor, defog,
or defrost modes. If recirculation is selected with one of
those modes, the indicator light flashes three times and
then turns off. The air conditioning compressor also
comes 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.
The recirculation mode can be turned off by pressing
the outside air button, or by turning off the ignition.
;(Outside Air): Press to turn the outside air mode
on. An indicator light on the button comes on to show
that outside is on. When selected, air from outside the

Appearance Care
Interior Cleaning
The vehicle's interior will continue to look its best if it is
cleaned often. Although not always visible, dust and dirt
can accumulate on the upholstery. Dirt can damage
carpet, fabric, leather, and plastic surfaces. Regular
vacuuming is recommended to remove particles from
the upholstery. It is important to keep the upholstery
from becoming and remaining heavily soiled. Soils
should be removed as quickly as possible. The
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 home furnishings may also transfer
color to the vehicle's interior.
When cleaning the vehicle's interior, only use cleaners
specifically 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:
Using abrasive cleaners when cleaning
glass surfaces on the vehicle, could scratch the
glass and/or cause damage to the rear window
defogger. When cleaning the glass on the vehicle,
use only a soft cloth and glass cleaner.
Many cleaners contain solvents that may become
concentrated in the vehicle's breathing space. Before
using cleaners, read and adhere to all safety
instructions on the label. While cleaning the vehicle's
interior, maintain adequate ventilation by opening the
vehicle's doors and windows.
Dust may be removed from small buttons and knobs
using a small brush with soft bristles.
Products that remove odors from the vehicle's
upholstery and clean the vehicle's glass can be
obtained from your dealer/retailer.
Do not clean the vehicle using:
.A knife or any other sharp object to remove a soil
from any interior surface.
.A stiff brush. It can cause damage to the vehicle's
interior surfaces.
.Heavy pressure or aggressive rubbing with a
cleaning cloth. Use of heavy pressure can damage
the interior and does not improve the effectiveness
of soil removal.
