7. Blower Control
Blower control is used to regulate the amount of air
forced through the climate system. There are seven
blower speeds available. Adjusting the blower will cause
automatic mode to switch to manual operation. The
speeds can be selected using either hard-keys or soft-keys
as follows:
Hard-Key
The blower speed increases as you turn the control
clockwise from the lowest blower setting. The blower
speed decreases as you turn the knob counterclockwise.
Soft-Key
Use the small blower icon to reduce the blower setting
and the large blower icon to increase the blower setting.
Blower can also be selected by pressing the blower bar
area between the icons.8. Climate Control OFF Button
Press and release this button to turn the Climate Control
ON/OFF.
9. Temperature Control Down Button
Push the button for cooler temperature settings. On the
touchscreen, slide the temperature bar towards the blue
arrow soft-key for cooler temperature settings.
10. Temperature Control Up Button

pressing the RECIRCULATION control button. Recircu-
lation mode should only be used temporarily. The recir-
culation LED will illuminate on the blower control knob
when this button is selected. Push the button 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
mode is not allowed in Defrost mode to improve window
clearing operation. Recirculation will be disabled auto-
matically if these modes are selected.Automatic Climate Controls With Touchscreen —

Operation” for more information.5. Front Defrost Button
Press and release to change the current airflow setting to
Defrost mode. The indicator illuminates when this fea-
ture is ON. Air comes from the windshield and side
window demist outlets. When the defrost button is
selected, the blower level will increase. Use Defrost mode

will automatically exit this feature.
10. Blower Control
Blower control is used to regulate the amount of air forced
through the climate system. There are seven blower speeds
available. Adjusting the blower will cause automatic mode
to switch to manual operation. The speeds can be selected
using either hard-keys or soft-keys as follows:
Hard-Key
The blower speed increases as you turn the control

11. Modes
The airflow distribution mode can be adjusted so air
comes from the instrument panel outlets, floor outlets,
demist 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
demist outlets. This mode works best in cold or
snowy conditions. 12. Climate Control OFF Button
Press and release this button to turn the Climate Control
ON/OFF.
13. Driver Temperature Control Down Button
Provides the driver with independent temperature con-
trol. Push the hard-key button for cooler temperature
settings or on the touchscreen, press and slide the soft-
key temperature bar towards the blue arrow soft-key for
cooler temperature settings.
NOTE:
In Sync mode, this button will also automatically
adjust the passenger temperature setting at the same
time.

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.
