RADIO OPERATION AND MOBILE PHONES
Under certain conditions, the mobile phone being on in
your vehicle can cause erratic or noisy performance from
your radio. This condition may be lessened or eliminated
by relocating the mobile phone antenna. This condition is
not harmful to the radio. If your radio performance does
not satisfactorily “clear” by the repositioning of the
antenna, it is recommended that the radio volume be
turned down or off during mobile phone operation when
not using Uconnect® (if equipped).
CLIMATE CONTROLS
The Climate Control System allows you to regulate the
temperature, amount, and direction of air circulating
throughout the vehicle. The controls are located on the
instrument panel below the radio.
Manual Climate Controls Without Touchscreen —
If Equipped
The controls for the manual heating and air conditioning
system in this vehicle consist of a series of outer rotary
dials and inner push knobs. These comfort controls can
be set to obtain desired interior conditions.

Front Blower Control
There are four 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: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.
358 UNDERSTANDING YOUR INSTRUMENT PANEL

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.

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.

Electronic Speed Control — If Equipped
•Do not use in hilly terrain or with heavy loads.
• When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
• Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, shift the trans-
mission into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed. Air Conditioning
Turn off temporarily.
Air Suspension System
To aid in attaching/detaching the trailer from the vehicle,
the air suspension system can be used. Refer to “Air
Suspension System” in “Starting and Operating” for
further information.
NOTE:
The vehicle must remain in the engine running
position while attaching a trailer for proper leveling of
the air suspension system.
SNOWPLOW
1500 Models Only
NOTE: Do not use this model vehicle for snowplow
applications.
