Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO), which is colorless and odorless.
Breathing it can make you unconscious 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 maintained 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 mispositioned 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.2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 97

Heated Seats — If Equipped
On 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, medication, alcohol use, ex-
haustion 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 damage 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 “Remote 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 instrument panel (below the climate con-
trols).

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 heating 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 a
maximum of 55 minutes of continuous operation. 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 a maximum of 45 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 passengers to operate the seats indepen-
dently. The heated seat switches for each heater are
located on the rear of the center console.

Ventilated Seats — If Equipped
On some models, both the driver and passenger seats are
ventilated. Located in the seat cushion and seatback are
small fans that draw the air from the passenger compart-
ment and blow air through fine perforations in the seat
cover to help keep the driver and front passenger cooler
in higher ambient temperatures.
There are two ventilated seat switches that allow the
driver and passenger to operate the seats independently.
The ventilated seat switches are located on the switch
bank in the center stack of the instrument panel, just
below the climate controls.

NOTE:For vehicles equipped with Driver Memory
Seat, you can use your Remote Keyless Entry (RKE)
transmitter or the memory switch on the driver’s door
trim panel to return the tilt/telescopic steering column to
pre-programmed positions. Refer to “Driver Memory
Seat” in this section for further information.
WARNING!
Do not adjust the steering column while driving.
Adjusting the steering column while driving or driv-
ing with the steering column unlocked, could cause
the driver to lose control of the vehicle. Be sure the
steering column is locked before driving your ve-
hicle. 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 temperature setting. Once the heated
steering wheel has been turned on it will operate for
approximately 58 to 70 minutes before automatically shut-
ting 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 indicator.
NOTE: The engine must be running for the heated
steering wheel to operate.

Gate Operator/Canadian Programming
Canadian radio frequency laws require transmitter sig-
nals to time-out (or quit) after several seconds of trans-
mission – which may not be long enough for HomeLink
to pick up the signal during programming. Similar to this
Canadian law, some U.S. gate operators are designed to
time-out in the same manner.
It may be helpful to unplug the device during the cycling
process to prevent possible overheating of the garage
door or gate motor.
If you are having difficulties programming a garage door
opener or a gate operator, replace “Programming
HomeLink” Step 3, with the following: 3. Continue to press and hold the HomeLink
button,
while you press and release (“cycle”), your handheld
transmitter every two seconds until HomeLink has
successfully accepted the frequency signal. The indica-
tor light will flash slowly and then rapidly when fully
trained.
If you unplugged the device for training, plug it back in
at this time.
Then proceed with Step 4 under “Programming
HomeLink,” earlier in this section.
Using HomeLink
To operate, press and release the programmed
HomeLink button. Activation will now occur for the
trained device (i.e., garage door opener, gate operator,
security system, entry door lock, home/office lighting,
etc.,). The handheld transmitter of the device may also be
used at any 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 window. Use a soft cloth
and a mild washing solution, wiping parallel to
the heating elements. Labels can be peeled off
after soaking with warm water.
•Do not use scrapers, sharp instruments, or abra-
sive 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 distributed over the luggage rack crossbars.
NOTE: If not equipped with crossbars, your authorized
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.
