SAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN THE
CARGO AREA.
WARNING!
•Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
• It is extremely dangerous to ride in a cargo
area, inside or outside of a vehicle. In a
collision, people riding in these areas are
more likely to be seriously injured or killed.
• Do not allow people to ride in any area of
your vehicle that is not equipped with seats
and seat belts.
• Be sure everyone in your vehicle is in a
seat and using a seat belt properly.
Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you uncon-
scious and can eventually poison you. To
avoid breathing (CO) follow these safety tips:
Do not run the engine in a closed garage or in
confined areas any longer than needed to
move your vehicle in or out of the area.
If it is necessary to sit in a parked vehicle with
the engine running, adjust your heating or
cooling controls to force outside air into the
vehicle. Set the blower at high speed.
If you are required to drive with the trunk/liftgate
open, make sure that all windows are closed
and the climate control BLOWER switch is set
at high speed. DO NOT use the recirculation
mode. The best protection against carbon monoxide
entry into the vehicle body is a properly main-
tained engine exhaust system.
Whenever a change is noticed in the sound of
the exhaust system, when exhaust fumes can
be detected inside the vehicle, or when the
underside or rear of the vehicle is damaged,
have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas
for broken, damaged, deteriorated, or misposi-
tioned parts. Open seams or loose connections
could permit exhaust fumes to seep into the
passenger compartment. In addition, inspect
the exhaust system each time the vehicle is
raised for lubrication or oil change. Replace as
required.

Front Passenger Seat Fold-Flat
Feature — If Equipped
To fold the seatback to the flat load-floor posi-
tion, lift the recline lever and push the seatback
forward. To return to the seating position, raise
the seatback and lock it into place.
Heated Seats — If EquippedOn some models, the front and rear seats may
be equipped with heaters in both the seat
cushions and seatbacks.
WARNING!
•Persons who are unable to feel pain to the
skin because of advanced age, chronic
illness, diabetes, spinal cord injury, medi-
cation, alcohol use, exhaustion or other
physical condition must exercise care when
using the seat heater. It may cause burns
even at low temperatures, especially if
used for long periods of time.
• Do not place anything on the seat that
insulates against heat, such as a blanket or
cushion. This may cause the seat heater to
overheat. Sitting in a seat that has been
overheated could cause serious burns due
to the increased surface temperature of the
seat.
CAUTION!
Repeated overheating of the seat could dam-
age the heating element and/or degrade the
material of the seat. Vehicles Equipped with Remote Start
On models that are equipped with remote start,
the driver’s heated seat can be programmed to
come on during a remote start. Refer to “Re-
mote Starting System — If Equipped” in
“Things to Know Before Starting Your Vehicle”
for further information.
Front Heated Seats
There are two heated seat switches that allow
the driver and passenger to operate the seats
independently. The controls for each heater are
located near the bottom center of the instru-
ment panel (below the climate controls).
You can choose from HIGH, LOW or OFF heat
settings. Amber indicator lights in each switch
indicate the level of heat in use. Two indicator
lights will illuminate for HIGH, one for LOW and
none for OFF.
Press the switch once to select
HIGH-level heating. Press the
switch a second time to select
LOW-level heating. Press the
switch a third time to shut the heat-
ing elements OFF.

NOTE:
Once a heat setting is selected, heat will be
felt within two to five minutes.
When the HIGH-level setting is selected, the
heater will provide a boosted heat level during
the first four minutes of operation. Then, the
heat output will drop to the normal HIGH-level.
If the HIGH-level setting is selected, the system
will automatically switch to LOW-level after ap-
proximately 30 minutes of continuous opera-
tion. At that time, the number of illuminated
LEDs changes from two to one, indicating the
change. The LOW-level setting will turn OFF
automatically after approximately 30 minutes.
Rear Heated Seats
On some models, the two outboard seats are
equipped with heated seats. There are two
heated seat switches that allow the rear pas-
sengers to operate the seats independently.
The heated seat switches for each heater are

ing. Adjusting the steering column while driv-
ing or driving with the steering column un-
locked, could cause the driver to lose control
of the vehicle. Be sure the steering column is
locked before driving your vehicle. Failure to
follow this warning may result in serious injury
or death.
HEATED STEERING WHEEL —
IF EQUIPPED
The steering wheel contains a heating element
that helps warm your hands in cold weather.
The heated steering wheel has only one tem-
perature setting. Once the heated steering
wheel has been turned on it will operate for
approximately 58 to 70 minutes before auto-
matically shutting off. The heated steering
wheel can shut off early or may not turn on
when the steering wheel is already warm.
The heated steering wheel switch is located on
the switch bank below the climate controls.Press the switch to turn
on the heated steering
wheel. The light on the
switch will illuminate to
indicate the steering
wheel heater is on.
Pressing the switch a
second time will turn off
the heated steering
wheel and light indica-
tor.
NOTE:
The engine must be running for the heated
steering wheel to operate.
Vehicles Equipped with Remote Start

the heated steering wheel and seat can be
programmed to come on during a remote start.
Refer to “Remote Starting System — If
Equipped” in “Things to Know Before Starting
Your Vehicle” for further information.
WARNING!
• Persons who are unable to feel pain to the
skin because of advanced age, chronic
illness, diabetes, spinal cord injury, medi-
cation, alcohol use, exhaustion, or other
physical conditions must exercise care
when using the steering wheel heater. It
may cause burns even at low tempera-
tures, especially if used for long periods.
• Do not place anything on the steering
wheel that insulates against heat, such as a
blanket or cushion. This may cause the
steering wheel heater to overheat.
ELECTRONIC SPEED CONTROLWhen engaged, the Electronic Speed Control
takes over accelerator operations at speeds
greater than 25 mph (40 km/h).
The Electronic Speed Control buttons are lo-
cated on the right side of the steering wheel.

If the liftgate flipper glass is open, the rear
window wiper/washer functionality is inter-
rupted and the wiper stops at that “park” posi-
tion. When the liftgate flipper glass is closed,
the rear wiper will resume wiper/washer func-
tionality after five seconds.
Rear Window Defroster
The rear window defroster button is
located on the climate control panel.
Press this button to turn on the rear
window defroster and the heated outside mir-
rors (if equipped). An indicator in the button will
illuminate when the rear window defroster is on.
The rear window defroster automatically turns
off after approximately 10 minutes. For an ad-
ditional five minutes of operation, press the
button a second time.
NOTE:
To prevent excessive battery drain, use the
rear window defroster only when the engine
is operating.
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 win-
dow. Use a soft cloth and a mild washing
solution, wiping parallel to the heating ele-
ments. Labels can be peeled off after soak-
ing with warm water.
• Do not use scrapers, sharp instruments, or
abrasive window cleaners on the interior
surface of the window.
• Keep all objects a safe distance from the
window.
ROOF LUGGAGE RACK —
IF EQUIPPED
The crossbars and siderails are designed to
carry the weight on vehicles equipped with a
luggage rack. The load must not exceed
150 lbs (68 kg), and should be uniformly dis-
tributed over the luggage rack crossbars. NOTE:
If not equipped with crossbars, your autho-
rized dealer can order and install MOPAR

crossbars built specifically for this roof rack
system.
Distribute cargo weight evenly on the roof rack
crossbars. The roof rack does not increase the
total load carrying capacity of the vehicle. Be
sure the total load of cargo inside the vehicle
plus that on the external rack does not exceed
the maximum vehicle load capacity.
The optional crossbars must be installed using
the correct orientation (the longer crossbar
toward the front).
To move the crossbars, loosen the attach-
ments, located at the upper edge of each
crossbar, approximately eight turns using the
anti-theft wrench provided with the MOPAR 
crossbars. Then, move the crossbar to the
desired position, keeping the crossbars paral-
lel to the rack frame. Once the crossbar is in the
desired position, retighten the with the wrench
to lock the crossbar into position.

non-essential electrical devices or increase en-
gine speed (if at idle). If the charging system
light remains on, it means that the vehicle is
experiencing a problem with the charging sys-
tem. Obtain SERVICE IMMEDIATELY. See an
authorized dealer.
If jump starting is required, refer to “Jump
Starting Procedures” in “What To Do In Emer-
gencies”.
•Electronic Throttle Control (ETC) Light
This light informs you of a problem
with the Electronic Throttle Control
(ETC) system. The light will come
on when the ignition is first turned
ON and remain on briefly as a bulb
check. If the light does not come
on during starting, have the system checked by
an authorized dealer.
If a problem is detected, the light will come on
while the engine is running. Cycle the ignition
key when the vehicle has completely stopped
and the shift lever is placed in the PARK
position. The light should turn off.
If the light remains lit with the engine running
your vehicle, will usually be drivable, however, see an authorized dealer for service as soon as
possible. If the light is flashing when the engine
is running, immediate service is required and
you may experience reduced performance, an
elevated/rough idle or engine stall and your
vehicle may require towing.
•
Engine Temperature Warning Light
This light warns of an overheated en-
gine condition. As temperatures rise
and the gauge approaches H,this
indicator will illuminate and a single
chime will sound after reaching a set threshold.
Further overheating will cause the temperature
gauge to pass H,the indicator will continuously
flash and a continuous chime will occur until
the engine is allowed to cool.
If the light turns on while driving, safely pull
over and stop the vehicle. If the A/C system is
on, turn it off. Also, shift the transmission into
NEUTRAL and idle the vehicle. If the tempera-
ture reading does not return to normal, turn the
engine off immediately and call for service.
Refer to “If Your Engine Overheats” in “What To
Do In Emergencies” for more information. •
Transmission Temperature Light
This light indicates that there is
excessive transmission fluid tem-
perature that might occur with se-
vere usage such as trailer towing.
It may also occur when operating
the vehicle in a high torque con-
verter slip condition, such as 4-wheel-drive
operation (e.g., snow plowing, off- road opera-
tion). If this light comes on, stop the vehicle and
run the engine at idle or faster, with the trans-
mission in NEUTRAL until the light goes off.
CAUTION!
Continuous driving with the Transmission
Temperature Indicator illuminated will eventu-
ally cause severe transmission damage or
transmission failure.

the left-hand control is different depending on
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

Overdrive Operation
The automatic transmission includes an elec-
tronically controlled Overdrive (fifth gear for
3.6L and 3.0L Diesel engine, fourth and fifth
gears for 5.7L engine). The transmission will
automatically shift to Overdrive, if the following
conditions are present:
•the shift lever is in DRIVE;
• the engine coolant has reached normal op-
erating temperature;
• vehicle speed is above approximately
30 mph (48 km/h);
• the TOW/HAUL switch has not been acti-
vated;
• transmission has reached normal operating
temperature.
NOTE:
If the vehicle is started in extremely cold
temperatures, the transmission may not
shift into Overdrive and will automatically
select the most desirable gear for operation
at this temperature. Normal operation will
resume when the transmission fluid tem-
perature has risen to a suitable level. Refer to the “Note” under “Torque Converter
Clutch” in this section.
During cold temperature operation you may
notice delayed upshifts, depending on en-
gine and transmission temperature. This
feature improves the warm-up time of the
engine and transmission.
If the transmission temperature gets ex-
tremely hot, the transmission will automati-
cally select the most desirable gear for op-
eration at this temperature. If the
transmission temperature becomes hot
enough, the “TRANSMISSION OVER TEMP”
message may display, and the transmission
may downshift out of Overdrive until the
transmission cools down. After cool down,
the transmission will resume normal opera-
tion.
The transmission will downshift from Overdrive,
to the most desirable gear, if the accelerator
pedal is fully pressed at vehicle speeds above
approximately 35 mph (56 km/h).
When to Use TOW/HAUL Mode –
If Equipped
When driving in hilly areas, towing a trailer,
carrying a heavy load, etc., and frequent trans-
mission shifting occurs, press the TOW/HAUL
switch. This will improve performance and re-
duce the potential for transmission overheating
or failure due to excessive shifting. When oper-
ating in TOW/HAUL mode, the transmission will
shift into direct gear and Overdrive will be
enabled under steady cruise conditions.
