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 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.
• 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. 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 113

Vehicles Equipped with Remote Start
On models that are equipped with remote start, the
driver ’s heated seat and heated steering wheel 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 informa-
tion.
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,

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 approximately 60 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 approximately 45 min-
utes.
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.

To tilt the steering column, move the lever up or down as
desired. To lengthen or shorten the steering column, pull
the lever toward you or push the lever away from you as
desired.
NOTE:For vehicles equipped with Driver Memory Seat,
you can use your Remote Keyless Entry (RKE) transmit-
ter 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. 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
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 indicator.

5. Press and hold the programmed HomeLinkbutton
and observe the indicator light.
• If the indicator light stays on constantly, program-
ming is complete and the garage door/device should
activate when the HomeLink button is pressed.
• To program the remaining two HomeLink buttons,
repeat each step for each remaining button. DO NOT
erase the channels.
Reprogramming A Single HomeLink Button
To reprogram a channel that has been previously trained,
follow these steps:
1. Cycle the ignition to the ON/RUN position.
2. Press and hold the desired HomeLink button until
the indicator light begins to flash after 20 seconds. Do
not release the button.
3. Without releasing the button proceed with “Program-
ming A Non-Rolling Code” Step 2 and follow all
remaining steps.
Canadian/Gate Operator Programming
For programming transmitters in Canada/United States
that require the transmitter signals to “time-out” after
several seconds of transmission.
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.
1. Cycle the ignition to the ON/RUN position.
2.
Place the hand-held transmitter 1 to 3 in (3 to 8 cm)
away from the HomeLink button you wish to program
while keeping the HomeLink indicator light in view.

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 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 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.
