NOTE:For vehicles equipped with Remote Start, the
climate controls will not function during Remote Start
operation if the blower control is left in the OFF position.
Temperature Control
Use this control to regulate the tem-
perature of the air inside the passenger
compartment. Rotating the knob coun-
terclockwise, from top center into the
blue area of the scale, indicates cooler
temperatures. Rotating the knob clock-
wise, into the red area, indicates
warmer temperatures.
Air Conditioning Operation
Push the A/C button to engage the Air
Conditioning (A/C). A LED will illu-
minate when the A/C system is
engaged.
MAX A/C
For maximum cooling, when MAX A/C is selected the
A/C is turned on automatically and the air is
recirculated.

NOTE:A/C cannot be deselected when in MAX A/C
position. The LED will blink three times if the A/C
button is pushed. If your air conditioning performance
seems lower than expected, check the front of the A/C
condenser (located in front of the radiator), for an accu-
mulation of dirt or insects. Clean with a gentle water
spray from behind the radiator and through the con-
denser. Fabric front fascia protectors may reduce airflow
to the condenser, reducing air conditioning performance.
Mode Control (Air Direction)
Mode control allows you to choose
from several patterns of air distribu-
tion. You can select either a primary
mode, as identified by the symbols, or
a blend of two of these modes. The closer the control is to a particular mode, the more air
distribution you receive from that mode.
Panel Mode
Air is directed through the outlets in the instru-
ment panel. These outlets can be adjusted to direct
airflow.
Bi-Level Mode
Air is directed through the panel and floor outlets.
NOTE: There is a difference in temperature (in
any conditions other than full cold or full hot), between
the upper and lower outlets for added comfort. The
warmer air goes to the floor outlets. This feature gives
improved comfort during sunny but cool conditions.

Floor Mode
Air is directed through the floor outlets with a
small amount through the defrost and side win-
dow demist outlets.
Mix Mode
Air is directed through the floor, defrost and side
window demist outlets. This setting works best in
cold or snowy conditions that require extra heat at the
windshield. This setting is good for maintaining comfort,
while reducing moisture on the windshield.
Defrost Mode
Air is directed through the windshield and side
window demist outlets. Use the DEFROST mode with maximum blower and warm temperature settings
for best windshield and side window defrosting.
NOTE:
The air conditioning compressor operates in MIX
and DEFROST, or a blend of these modes even if the A/C
button is not pressed. This dehumidifies the air to help
dry the windshield. To improve fuel economy, use these
modes only when necessary.
Recirculation Control
Press the Recirculation Control button to
choose between outside air intake or recircula-
tion of the air inside the vehicle. A LED will
illuminate when you are in Recirculation
mode. Only use the Recirculation mode to temporarily
block out any outside odors, smoke, or dust, and to cool
the interior rapidly upon initial start-up in very hot or
humid weather.

6. Modes
The airflow distribution mode can be adjusted so air
comes from the instrument panel outlets, floor outlets,
demister outlets and defrost outlets. The Mode settings
are as follows:
•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.
There is a shut off wheel located below the air vanes to
shut off or adjust the amount of airflow from these
outlets.
• 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 con-
ditions to provide cooler air out of the panel outlets and
warmer air from the floor outlets.
• Floor Mode
Air comes from the floor outlets. A slight amount
of air is directed through the defrost and side
window demister outlets.
• Mix Mode
Air comes from the floor, defrost and side window
demister outlets. This mode works best in cold or
snowy conditions.
NOTE: The air conditioning compressor operates in MIX
and DEFROST modes even if the A/C button is not
pressed. This dehumidifies the air to help dry the wind-
shield. To improve fuel economy, utilize these modes
only when required.

on low until the engine warms up. The blower will
increase in speed and transition into Auto mode.
Recirculation Control
When outside air contains smoke, odors, or
high humidity, or if rapid cooling is desired,
you may wish to recirculate interior air by
pressing the RECIRCULATION control button.
Recirculation mode should only be used temporarily. The
recirculation LED will illuminate on the soft and hard
keys when either button is selected. Push either soft or
hard key a second time to turn off the Recirculation mode
LED and allow outside air into the vehicle.
NOTE: In cold weather, use of Recirculation mode may
lead to excessive window fogging. The recirculation
feature may be unavailable (soft-key button greyed out)
if conditions exist that could create fogging on the inside
of the windshield. On systems with Manual Climate Controls, the recirculation mode is not allowed in Defrost
mode to improve window clearing operation. Recircula-
tion will be disabled automatically if this mode is se-
lected. Attempting to use Recirculation while in this
mode will cause the LED in the control button to blink
and then turn off.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corro-
sion protection and to protect against engine overheating.
OAT coolant (conforming to MS-12106) is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is function-
ing properly and the proper amount, type, and concen-
tration of coolant is used. Refer to “Maintenance
374 UNDERSTANDING YOUR INSTRUMENT PANEL

Procedures” in “Maintaining Your Vehicle” for proper
coolant selection. Use of the air Recirculation mode
during Winter months is not recommended because it
may cause window fogging.
Vacation/Storage
Any time 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 in high. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
Window Fogging and Frosting
Vehicle windows tend to fog on the inside of the glass in
mild, rainy and/or humid weather. Windows may frost
on the inside of the glass in very cold weather. To clear
the windows, select Defrost or Mix mode and increasethe front blower speed. Do not use the Recirculation
mode without A/C for long periods, as fogging may
occur.
NOTE:
Automatic Temperature Controls (ATC) will au-
tomatically adjust the climate control settings to reduce
or eliminate window fogging on the front windshield.
When this occurs, recirculation will be unavailable.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves. Leaves
collected in the air intake may reduce airflow, can cause
odor, 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.

Autostop, the Climate Controls system may automati-
cally adjust airflow to maintain cabin comfort. Customer
settings will be maintained upon return to an engine
running condition.
Possible Reasons The Engine Does Not AUTO
STOP
Prior to engine shut down, the system will check many
safety and comfort conditions to see if they are fulfilled.
In following situations the engine will not stop:
•Driver ’s seat belt is not buckled
• Driver ’s door is not closed
• Outside temperature is less than 1°F (–17°C) or greater
than 104°F (40°C)
• Battery temperature too warm or cold
• The vehicle is on a steep grade •
Cabin heating or cooling is in process and an accept-
able cabin temperature has not been achieved
• HVAC is set to full defrost mode at a high blower
speed
• Engine has not reached normal operating temperature
• Battery discharged
• The transmission is not in DRIVE
• Hood is open
• Vehicle is in 4LO transfer case mode
Other factors which can inhibit AutoStop include: fuel
level, accelerator pedal input, engine temp too high and
steering angle.
It may be possible for the vehicle to be driven several
times without the STOP/START system going into a
STOP/START READY state under more extreme condi-
tions of the items listed above.
