VOICE COMMAND — IF EQUIPPED
Voice Command System Operation
This Voice Command system al-
lows you to control your AM, FM
radio, disc player, and a memo
recorder.
NOTE:
Take care to speak into the Voice Interface
System as calmly and normally as possible.
The ability of the Voice Interface System to
recognize user voice commands may be
negatively affected by rapid speaking or a
raised voice level.
WARNING!
Any voice commanded system should be
used only in safe driving conditions following
local laws. All attention should be kept on the
roadway ahead. Failure to do so may result in
a collision causing serious injury or death. When you press the Voice Command
button, you will hear a beep. The beep is your
signal to give a command.
NOTE:
If you do not say a command within a few
seconds, the system will present you with a
list of options.
If you ever wish to interrupt the system while it
lists options, press the Voice Command
button, listen for the beep, and say your com-
mand.
Pressing the Voice Command
button
while the system is speaking is known as
“barging in.” The system will be interrupted,
and after the beep, you can add or change
commands. This will become helpful once you
start to learn the options.
NOTE:
At any time, you can say the words “Can-
cel”, “Help” or “Main Menu”. These commands are universal and can be
used from any menu. All other commands can
be used depending upon the active applica-
tion.
When using this system, you should speak
clearly and at a normal speaking volume.
The system will best recognize your speech if
the windows are closed, and the heater/air
conditioning fan is set to low.
At any point, if the system does not recognize
one of your commands, you will be prompted to
repeat it.
To hear the first available Menu, press the Voice
Command
button and say “Help” or
“Main Menu”.
CommandsThe Voice Command system understands two
types of commands. Universal commands are
available at all times. Local commands are
available if the supported radio mode is active.

which mode you are in.
The following describes the left-hand control
operation in each mode.
Radio OperationPressing the top of the switch will “Seek” up for
the next listenable station and pressing the
bottom of the switch will “Seek” down for the
next listenable station.
The button located in the center of the left-hand
control will tune to the next preset station that
you have programmed in the radio preset
pushbutton.
CD PlayerPressing the top of the switch once will go to
the next track on the CD. Pressing the bottom of
the switch once will go to the beginning of the
current track, or to the beginning of the previ-
ous track if it is within one second after the
current track begins to play.
If you press the switch up or down twice, it
plays the second track; three times, it will play
the third, etc.The center button on the left side rocker switch
has no function for a single-disc CD player.
However, when a multiple-disc CD player is
equipped on the vehicle, the center button will
select the next available CD in the player.
CD/DVD DISC MAINTENANCETo keep a CD/DVD in good condition, take the
following precautions:
1. Handle the disc by its edge; avoid touching
the surface.
2. If the disc is stained, clean the surface with
a soft cloth, wiping from center to edge.
3. Do not apply paper or tape to the disc; avoid
scratching the disc.
4. Do not use solvents such as benzene, thin-
ner, cleaners, or anti-static sprays.
5. Store the disc in its case after playing.
6. Do not expose the disc to direct sunlight.
7. Do not store the disc where temperatures
may become too high.
NOTE:
If you experience difficulty in playing a par-
ticular disc, it may be damaged (i.e.,
scratched, reflective coating removed, a
hair, moisture or dew on the disc) oversized,
or have protection encoding. Try a known
good disc before considering disc player
service.
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 condi-
tion may be lessened or eliminated by relocat-
ing the mobile phone antenna. This condition is
not harmful to the radio. If your radio perfor-
mance does not satisfactorily “clear” by the
repositioning of the antenna, it is recom-
mended that the radio volume be turned down
or off during mobile phone operation.
CLIMATE CONTROLSThe Air Conditioning and Heating System is
designed to make you comfortable in all types
of weather.
185

Dual-Zone Manual Heating and Air
Conditioning
The Dual-Zone Manual Climate Controls allow
both driver and front passenger seat occu-
pants to select individual comfort settings. The
controls consist of a series of outer rotary dials
and inner push knobs.Blower Control
Rotate this control to
regulate the amount of
air forced through the
ventilation system in
any mode. The blower
speed increases as you
move the control to the
right from the “O” (OFF)
position. There are
seven blower speeds.
Temperature Controls
• Driver Temperature Control
Rotate this control to
regulate the tempera-
ture of the air inside the
passenger compart-
ment for the left front
seat occupant. Rotating
the dial left into the blue
area of the scale indi-
cates cooler tempera-
tures while rotating right
into the red area indicates warmer tempera-
tures. •
Passenger Temperature Control
Rotate this control to
regulate the tempera-
ture of the air inside the
passenger compart-
ment for the right front
seat occupant. Rotating
the dial left into the blue
area of the scale indi-
cates cooler tempera-
tures while rotating right
into the red area indicates warmer tempera-
tures.
NOTE:
If your air conditioning performance seems
lower than expected, check the front of the
A/C condenser located in front of the radia-
tor for an accumulation of dirt or insects.
Clean with a gentle water spray from behind
the radiator and through the condenser.
Fabric front fascia protectors may reduce
airflow to the condenser, reducing air con-
ditioning performance.
186

Mode Control (Air Direction)
Push the mode control buttons to choose from
several patterns of air distribution.
PanelAir is directed through the outlets in the
instrument panel. These outlets can be
adjusted to direct airflow.
NOTE:
The center instrument panel outlets can be
aimed so that they are directed toward the
rear seat passengers for maximum airflow
to the rear.
Bi-Level Air is directed through the panel and
floor outlets.
NOTE:
For all settings except full cold or full hot,
there is a difference in temperature between
the upper and lower outlets. The warmer air
flows to the floor outlets. This feature gives
improved comfort during sunny but cool
conditions. Floor
Air is directed through the floor outlets
with a small amount flowing through the
defrost and side window demist outlets.
Mix 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 to the
windshield. This setting is good for maintaining
comfort while reducing moisture on the wind-
shield.
Defrost Air is directed through the windshield
and side window demist outlets. Use
this mode with maximum blower and
temperature settings for best windshield and
side window defrosting.
NOTE:
• In Floor, Mix and Defrost modes a small
amount of air will flow through the out-
board panel outlets for occupant comfort.
• The air conditioning compressor oper-
ates in Mix, Defrost, or a blend of these
modes, even if the Air Conditioning (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 Pressing the Recirculation Control
button will put the system in recir-
culation mode. This can be used
when outside conditions such as
smoke, odors, dust, or high humid-
ity are present. Activating recircu-
lation will cause the LED in the control button to
illuminate.
NOTE:
• Continuous use of the recirculation mode
may make the inside air stuffy and win-
dow 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 Out-
side Air position for maximum defogging.
• The A/C will engage automatically to pre-
vent fogging when the recirculation but-
187

ton is pressed and the mode control is set
to panel or panel / floor.
• The A/C can be deselected manually with-
out disturbing the mode control selection.
• When the ignition switch is turned to the
LOCK position or the ignition switch
START/STOP button is cycled to OFF, the
recirculation feature will be cancelled.
Air Conditioning Control Press this button to en-
gage the Air Condition-
ing. A light will illumi-
nate when the Air
Conditioning System is
engaged. Rotating the
dial left into the blue
area of the scale indi-
cates cooler tempera-
tures while rotating right
into the red area indicates warmer tempera-
tures.
NOTE:
The air conditioning compressor will not
engage until the engine has been running
for about 10 seconds. •
MAX A/C
For maximum cooling use the A/C and recircu-
lation buttons at the same time.
• ECONOMY MODE
If economy mode is desired, press the A/C
button to turn OFF the indicator light and the
A/C compressor. Then, move the temperature
control to the desired temperature.

allows both driver and front passenger seat
occupants to select individual comfort set-
tings.
• When occupants in the vehicle select an
Auto mode operation, Auto blower operation
is set by using a push button on the control
unit and a comfort temperature setting by
using the temperature up and down buttons.
• The system provides set-and-forget opera-
tion for optimum comfort and convenience.
• The system can be controlled manually, if
desired. The ATC system automatically maintains the
interior comfort level desired by the driver and
passenger.

Automatic Temperature Control (ATC) Panel
188

NOTE:
In many temperature positions, the BI-
LEVEL mode is designed 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 ModeAir comes from the floor, defrost and
side window demist outlets. This mode
works best in cold or snowy conditions.
It allows you to stay comfortable while
keeping the windshield clear.
Defrost Mode Air comes from the windshield and side
window demist outlets. Use Defrost
mode with maximum temperature set-
tings for best windshield and side window
defrosting. When the defrost mode is selected,
the blower will automatically default to medium-
high unless the blower is controlled manually. NOTE:
While operating in the other modes, the
system will not automatically sense the
presence of fog, mist or ice on the wind-
shield. Defrost mode must be manually se-
lected to clear the windshield and side
glass.
Air Conditioning (A/C)
The Air Conditioning (A/C) button allows the
operator to manually activate or deactivate the
air conditioning system. When in A/C mode and
the ATC is set to a cool temperature, dehumidi-
fied air flows through the air outlets. If Economy
mode is desired, press the A/C button to turn
off the A/C mode in the ATC display and
deactivate the A/C system.
NOTE:
•
If the system is in Mix, Floor or Defrost
Mode, the A/C can be turned off, but the
A/C system shall remain active to prevent
fogging of the windows.
• If fog or mist appears on the windshield or
side glass, select Defrost mode and in-
crease blower speed. 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 but-
ton. Recirculation mode should
only be used temporarily. The recirculation LED
will illuminate 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 the
Floor/Defrost Mix and Defrost modes to im-
prove window clearing operation. Recircula-
tion will be disabled automatically if these
modes are selected.

Operating Tips
Window Fogging
Windows will fog on the inside when the humid-
ity inside the vehicle is high. This often occurs
in mild or cool temperatures when it’s rainy or
humid. In most cases, turning the air condition-
ing (pressing the A/C button) on will clear the
fog. Adjust the temperature control, air direc-
tion, and blower speed to maintain comfort.
As the temperature gets colder, it may be
necessary to direct air onto the windshield.
Adjust the temperature control and blower
speed to maintain comfort. Higher blower
speeds will reduce fogging. Interior fogging on
the windshield can be quickly removed by
selecting the DEFROST mode.Regular cleaning of the inside of the windows
with a non-filming cleaning solution (vinegar
and water works very well) will help prevent
contaminates (cigarette smoke, perfumes, etc.)
from sticking to the windows. Contaminates
increase the rate of window fogging.
Summer Operation
NOTE:
In some cases during high temperature
trailer tow operation the Air Conditioning
system performance may be reduced. This
is to help protect the engine from overheat-
ing during the high load condition.
Your air conditioning system is also equipped
with an automatic recirculation system. When
the system senses a heavy load or high heat
conditions, it may use partial Recirculation A/C
mode to provide additional comfort.Winter Operation
When operating the system during the winter
months, make sure the air intake, located di-
rectly in front of the windshield, is free of ice,
slush, snow, or other obstructions.
Vacation Storage
Anytime 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 the fresh air and high blower
setting. This will ensure adequate system lubri-
cation to minimize the possibility of compressor
damage when the system is started again.

sive shifting and heat buildup. This action
will also provide better engine braking.
The transmission fluid and filter should be
changed if you REGULARLY tow a trailer for
more than 45 minutes of continuous operation.
Refer to “Maintenance Schedule” for the proper
maintenance intervals.
NOTE:
Check the transmission fluid level before
towing (5.7L engine).
To help maintain a comfortable operating
temperature for your transmission, it is rec-
ommended that when towing a maximum
loaded trailer up steep grades with switch
backs, you should use the ERS function on
the transmission shifter to lock your vehicle
into first gear (5.7L Models Only).
Electronic Speed Control – If Equipped
Do not use in hilly terrain or with heavy loads.
When using the speed control, if you expe-rience 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
overheating, take the following actions:
City Driving
When stopped for short periods of time, shift
the transmission into NEUTRAL and increase
engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
Trailer Hitch Attaching Points
Your vehicle will require extra equipment to tow
a trailer safely and efficiently. The trailer tow
hitch must be attached to your vehicle using
the provided attaching points on the vehicle’s
frame. Refer to the following chart to determine
the accurate attaching points. Other equip-
ment, such as trailer sway controls and braking
equipment, trailer equalizing (leveling) equip-
ment and low profile mirrors, may also be
required or strongly recommended.
Trailer Tow Hitch Attaching Points And Overhang Dimensions
Fixed, Detach
and Retractable Hitch
A 1.85 ft. (565 mm)
B 2.09 ft. (636 mm)

CAUTION!
•It is essential when replacing the cables on
the battery that the positive cable is at-
tached to the positive post, and the nega-
tive cable is attached to the negative post.
Battery posts are marked (+) positive and
(-) negative and identified on the battery
case.
• If a “fast charger” is used while battery is in
the vehicle, disconnect both vehicle battery
cables before connecting the charger to the
battery. Do not use a “fast charger” to
provide starting voltage.
Air Conditioner MaintenanceFor best possible performance, your air condi-
tioner should be checked and serviced by an
authorized dealer at the start of each warm
season. This service should include cleaning of
the condenser fins and a performance test.
Drive belt condition should also be checked at
this time.
CAUTION!
Do not use chemical flushes in your air con-
ditioning system as the chemicals can dam-
age your air conditioning components. Such
damage is not covered by the New Vehicle
Limited Warranty.
WARNING!
• Use only refrigerants and compressor lubri-
cants approved by the manufacturer for
your air conditioning system. Some unap-
proved refrigerants are flammable and can
explode, injuring you. Other unapproved
refrigerants or lubricants can cause the
system to fail, requiring costly repairs.
• The air conditioning system contains refrig-
erant under high pressure. To avoid risk of
personal injury or damage to the system,
adding refrigerant or any repair requiring
lines to be disconnected should be done by
an experienced repairman. NOTE:
Use only manufacturer approved A/C Sys-
tem Sealers, Stop Leak Products, Seal Con-
ditioners, Compressor Oil, and Refrigerants.
Refrigerant Recovery and Recycling
R-134a Air Conditioning Refrigerant is a hydro-
fluorocarbon (HFC) that is endorsed by the
Environmental Protection Agency (EPA) and is
an ozone-saving product. However, the manu-
facturer recommends that air conditioning ser-
vice be performed by authorized dealers or
other service facilities using recovery and recy-
cling equipment.
Body LubricationLocks and all body pivot points, including such
items as seat tracks, door hinge pivot points
and rollers, liftgate, tailgate, sliding doors and
hood hinges, should be lubricated periodically
with a lithium based grease, such as MOPAR

Spray White Lube or equivalent to assure quiet,
easy operation and to protect against rust and
wear. Prior to the application of any lubricant,
the parts concerned should be wiped clean to
remove dust and grit; after lubricating excess
oil and grease should be removed. Particular
