lever. For information on using the rear win-
dow wiper/washer, refer to “Rear Window
Wiper/Washer” in this section for more infor-
mation.
Windshield Wiper Operation
Rotate the end of the lever upward to the
second detent past the intermittent settings
for low-speed wiper operation. Rotate the end
of the lever upward to the third detent past
the intermittent settings for high-speed wiper
operation.
CAUTION!
In cold weather, always turn off the wiper
switch and allow the wipers to return to the
park position before turning off the engine.
If the wiper switch is left on and the wipers
freeze to the windshield, damage to the
wiper motor may occur when the vehicle is
restarted.
Intermittent Wiper System
Use the intermittent wiper when weather con-
ditions make a single wiping cycle, with a
variable pause between cycles, desirable. Ro-
tate the end of the lever to the first detent
position for one of five intermittent settings.
The delay cycle can be set anywhere between
1 to 18 seconds.
NOTE:
The wiper delay times depend on vehicle
speed. If the vehicle is moving less than
10 mph (16 km/h), delay times will be
doubled.
Windshield Washers
To use the washer, pull the lever toward you
and hold while spray is desired. If the lever is
pulled while in the delay range, the wiper will
start and continue to operate for two or three
wipe cycles after the lever is released. Then,
the intermittent interval previously selected
will resume.
If the lever is pulled while in the off position,
the wipers will operate for two or three wipe
cycles. Then, the wipers will turn off.
WARNING!
Sudden loss of visibility through the wind-
shield could lead to a collision. You might
not see other vehicles or other obstacles.
To avoid sudden icing of the windshield
during freezing weather, warm the wind-
shield with the defroster before and during
windshield washer use.
Mist Feature
Push down on the wiper lever to activate a
single wipe to clear off road mist or spray
from a passing vehicle. As long as the lever is
held down, the wipers will continue to oper-
ate.
NOTE:
The mist feature does not activate the washer
pump; therefore, no washer fluid will be
sprayed on the windshield. The wash func-
tion must be used in order to spray the
windshield with washer fluid.

position for rear wiper operation.
Rotate the switch upward past the first detent
to activate the rear washer. The washer pump
and the wiper will continue to operate as long
as the switch is held. Upon release, the wiper
will cycle two to three times before returning
to the set position.
If the rear wiper is operating when the igni-
tion is turned to the LOCK position, the wiper
will automatically return to the “park” posi-
tion. When the vehicle is restarted, the wiper
will resume function at whichever position
the switch is set at.

be used when outside conditions such as smoke, odors, dust, or high humidity are present.
NOTE:
• Continuous use of the Recirculation mode may make the inside air stuffy and window fogging may occur. Extended
use of this mode is not recommended.
• The use of the Recirculation mode in cold or damp weather could cause windows to fog on the inside, because of
moisture buildup inside the vehicle. Select the outside air position for maximum defogging.
• Recirculation can be used in all modes except for Defrost.
• The A/C can be deselected manually without disturbing the mode control selection.
Rear Defrost Button
Push and release the Rear Defrost Control button to turn on the rear window defroster and the heated outside mirrors
(if equipped). An indicator will illuminate when the rear window defroster is on. The rear window defroster automati-
cally turns off after ten minutes.

Icon Description
Temperature Control
Use this control to regulate the temperature of the air inside the passenger compartment. Rotating the knob counter-
clockwise, from top center into the blue area of the scale, indicates cooler temperatures. Rotating the knob clockwise,
into the red area, indicates warmer temperatures.
Blower Control
There are seven blower speeds. Use this control to regulate the amount of air forced through the system in any mode
you select. The blower speed increases as you move the control clockwise from the off position.
NOTE:
Depending on the configuration, your vehicle may be equipped with four blower speeds.
Modes Control
Turn the knob to adjust airflow distribution. The airflow distribution mode can be adjusted so air comes from the instru-
ment panel outlets, floor outlets, defrost outlets and demist outlets. The Mode settings are as follows:
Panel Mode
Panel Mode
Air comes from the outlets in the instrument panel. Each of these outlets can be individually adjusted to direct the flow
of air. The air vanes of the center outlets and outboard outlets can be moved up and down or side to side to regulate
airflow direction.
Bi-Level Mode
Bi-Level Mode
Air comes from the instrument panel outlets and floor outlets. A slight amount of air is directed through the defrost and
side window demister outlets.
NOTE:
Bi-Level mode is designed under comfort conditions to provide cooler air out of the panel outlets and warmer air from
the floor outlets.

Automatic Temperature Control (ATC) —
If Equipped
Automatic Operation
1. Push the AUTO button on the faceplate on
the Automatic Temperature Control (ATC)
Panel.
2. Next, adjust the temperature you would
like the system to maintain by adjusting
the driver and passenger temperature
control buttons. Once the desired tem-
perature is displayed, the system will
achieve and automatically maintain that
comfort level.
3. When the system is set up for your comfort
level, it is not necessary to change the
settings. You will experience the greatest
efficiency by simply allowing the system
to function automatically.
NOTE:
• It is not necessary to move the temperature
settings for cold or hot vehicles. The system
automatically adjusts the temperature,
mode, and blower speed to provide comfort
as quickly as possible.To provide you with maximum comfort in the
Automatic mode during cold start-ups, the
blower fan will remain on low until the engine
warms up. The blower will increase in speed
and transition into Auto mode.
Manual Operation Override
This system offers a full complement of
manual override features. The AUTO symbol
in the front ATC display will be turned off
when the system is being used in the manual
mode.
Operating Tips
Summer Operation
The engine cooling system must be protected
with a high-quality antifreeze coolant to pro-
vide proper corrosion protection and to pro-
tect against engine overheating. OAT coolant
(conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and de-
froster performance, make sure the engine
cooling system is functioning properly and
the proper amount, type, and concentrationof coolant is used. Use of the Air Recircula-
tion mode during Winter months is not rec-
ommended, because it may cause window
fogging.
Vacation/Storage
Before you store your vehicle, or keep it out of
service (i.e., vacation) for two weeks or more,
run the air conditioning system at idle for
about five minutes, in fresh air with the
blower setting on high. This will ensure ad-
equate system lubrication to minimize the
possibility of compressor damage when the
system is started again.
Window Fogging
Vehicle windows tend to fog on the inside in
mild, rainy, and/or humid weather. To clear
the windows, select Defrost or Mix mode and
increase the front blower speed. Do not use
the Recirculation mode without A/C for long
periods, as fogging may occur.
37

CAUTION!
Failure to follow these cautions can cause
damage to the heating elements:
• Use care when washing the inside of
the rear window. Do not use abrasive
window cleaners on the interior surface
of the window. Use a soft cloth and a
mild washing solution, wiping parallel
to the heating elements. Labels can be
peeled off after soaking with warm
water.
• Do not use scrapers, sharp instru-
ments, or abrasive window cleaners on
the interior surface of the window.
• Keep all objects a safe distance from
the window.
Outside Air Intake
Make sure the air intake, located directly in
front of the windshield, is free of obstruc-
tions, such as leaves. Leaves collected in the
air intake may reduce airflow, and if they
enter the plenum, they could plug the water
drains. In Winter months, make sure the air
intake is clear of ice, slush, and snow.
Cabin Air Filter
The climate control system filters out dust
and pollen from the air. Contact an autho-
rized dealer to service your cabin air filter,
and to have it replaced when needed.
POWER WINDOWS — IF
EQUIPPED
The power window switches are located on
the instrument panel below the radio. Push
the switch downward to open the window and
upward to close the window.
The top left switch controls the left front
window and the top right switch controls the
right front window.
WARNING!
Never leave children unattended in a ve-
hicle, and do not let children play with
power windows. Do not leave the key fob in
or near the vehicle, or in a location acces-
sible to children. Occupants, particularly
WARNING!
unattended children, can become en-
trapped by the windows while operating
the power window switches. Such entrap-
ment may result in serious injury or death.
