Air Bag Warning Light
The ORC monitors the readiness of the electronic
parts of the air bag system whenever the ignition
switch is in the AVV/START or MAR/ACC/
ON/RUN position. If the ignition switch is in the
STOP/OFF/LOCK position the air bag system is not on
and the air bags will not inflate.
The ORC contains a backup power supply system that may
deploy the air bag system even if the battery loses power or
it becomes disconnected prior to deployment. The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight seconds
for a self-check when the ignition switch is in the MAR/
ACC/ON/RUN position. After the self-check, the Air Bag
Warning Light will turn off. If the ORC detects a malfunc-
tion in any part of the system, it turns on the Air Bag
Warning Light, either momentarily or continuously. A
single chime will sound to alert you if the light comes on
again after initial startup.
The ORC also includes diagnostics that will illuminate the
instrument panel Air Bag Warning Light if a malfunction is
detected that could affect the air bag system. The diagnos-
tics also record the nature of the malfunction. While the air
bag system is designed to be maintenance free, if any of the
following occurs, have an authorized dealer service the air
bag system immediately.
•
The Air Bag Warning Light does not come on during the
four to eight seconds when the ignition switch is first in
the MAR/ACC/ON/RUN position.
• The Air Bag Warning Light remains on after the four to
eight-second interval.
• The Air Bag Warning Light comes on intermittently or
remains on while driving.
118 SAFETY

WARNING!(Continued)
•Never place a rear-facing child restraint in front of an
air bag. A deploying passenger front air bag can
cause death or serious injury to a child 12 years or
younger, including a child in a rear-facing child
restraint.
• Only use a rear-facing child restraint in a vehicle
with a rear seat.
Driver and Passenger Front Air Bag Features
The Advanced Front Air Bag system has multistage driver
and front passenger air bags. This system provides output
appropriate to the severity and type of collision as deter-
mined by the Occupant Restraint Controller (ORC), which
may receive information from the front impact sensors (if
equipped) or other system components.
The first stage inflator is triggered immediately during an
impact that requires air bag deployment. A low energy
output is used in less severe collisions. A higher energy
output is used for more severe collisions.
This vehicle may be equipped with a driver and/or front
passenger seat belt buckle switch that detects whether the
driver or front passenger seat belt is buckled. The seat belt buckle switch may adjust the inflation rate of the Ad-
vanced Front Air Bags.
WARNING!
•
No objects should be placed over or near the air bag
on the instrument panel or steering wheel because
any such objects could cause harm if the vehicle is in
a collision severe enough to cause the air bag to
inflate.
• Do not put anything on or around the air bag covers
or attempt to open them manually. You may damage
the air bags and you could be injured because the air
bags may no longer be functional. The protective
covers for the air bag cushions are designed to open
only when the air bags are inflating.
• Relying on the air bags alone could lead to more
severe injuries in a collision. The air bags work with
your seat belt to restrain you properly. In some
collisions, air bags won’t deploy at all. Always wear
your seat belts even though you have air bags.
Front Air Bag Operation
Front Air Bags are designed to provide additional protec-
tion by supplementing the seat belts. Front air bags are not
expected to reduce the risk of injury in rear, side, or
120 SAFETY

rollover collisions. The front air bags will not deploy in all
frontal collisions, including some that may produce sub-
stantial vehicle damage — for example, some pole colli-
sions, truck underrides, and angle offset collisions.
On the other hand, depending on the type and location of
impact, front air bags may deploy in crashes with little
vehicle front-end damage but that produce a severe initial
deceleration.
Because air bag sensors measure vehicle deceleration over
time, vehicle speed and damage by themselves are not good
indicators of whether or not an air bag should have deployed.
Seat belts are necessary for your protection in all collisions,
and also are needed to help keep you in position, away
from an inflating air bag.
When the ORC detects a collision requiring the front air
bags, it signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the front air bags.
The steering wheel hub trim cover and the upper right side
of the instrument panel separate and fold out of the way as
the air bags inflate to their full size. The front air bags fully
inflate in less time than it takes to blink your eyes. The front
air bags then quickly deflate while helping to restrain the
driver and front passenger.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees of the
driver and front passenger, and position the front occu-
pants for improved interaction with the front air bags.
WARNING!
•Do not drill, cut, or tamper with the knee impact
bolsters in any way.
• Do not mount any accessories to the knee impact
bolsters such as alarm lights, stereos, citizen band
radios, etc.
Supplemental Driver Knee Air Bag
This vehicle is equipped with a Supplemental Driver Knee
Air Bag mounted in the instrument panel below the
steering column. The Supplemental Driver Knee Air Bag
provides enhanced protection during a frontal impact by
working together with the seat belts, pretensioners, and
front air bags.
Supplemental Side Air Bags
Supplemental Seat-Mounted Side Air Bags (SABs)
This vehicle is equipped with Supplemental Seat-Mounted
Side Air Bags (SABs).

SAFETY 121

Side Impacts
The Side Air Bags are designed to activate in certain side
impacts. The Occupant Restraint Controller (ORC) deter-
mines whether the deployment of the Side Air Bags in a
particular impact event is appropriate, based on the sever-
ity and type of collision. The side impact sensors aid the
ORC in determining the appropriate response to impact
events. The system is calibrated to deploy the Side Air Bags
on the impact side of the vehicle during impacts that
require Side Air Bag occupant protection. In side impacts,
the Side Air Bags deploy independently; a left side impact
deploys the left Side Air Bags only and a right-side impact
deploys the right Side Air Bags only. Vehicle damage by
itself is not a good indicator of whether or not Side Air
Bags should have deployed.
The Side Air Bags will not deploy in all side collisions,
including some collisions at certain angles, or some side
collisions that do not impact the area of the passenger
compartment. The Side Air Bags may deploy during
angled or offset frontal collisions where the front air bags
deploy.Side Air Bags are a supplement to the seat belt restraint
system. Side Air Bags deploy in less time than it takes to
blink your eyes.
WARNING!
•
Occupants, including children, who are up against or
very close to Side Air Bags can be seriously injured
or killed. Occupants, including children, should
never lean on or sleep against the door, side win-
dows, or area where the side air bags inflate, even if
they are in an infant or child restraint.
• Seat belts (and child restraints where appropriate)
are necessary for your protection in all collisions.
They also help keep you in position, away from an
inflating Side Air Bag. To get the best protection
from the Side Air Bags, occupants must wear their
seat belts properly and sit upright with their backs
against the seats. Children must be properly re-
strained in a child restraint or booster seat that is
appropriate for the size of the child.

If A Deployment Occurs
The front air bags are designed to deflate immediately after
deployment.
NOTE: Front and/or side air bags will not deploy in all
collisions. This does not mean something is wrong with the
air bag system.
If you do have a collision which deploys the air bags, any
or all of the following may occur:
• The air bag material may sometimes cause abrasions
and/or skin reddening to the occupants as the air bags
deploy and unfold. The abrasions are similar to friction
rope burns or those you might get sliding along a carpet
or gymnasium floor. They are not caused by contact with
chemicals. They are not permanent and normally heal
quickly. However, if you haven’t healed significantly
within a few days, or if you have any blistering, see your
doctor immediately. •
As the air bags deflate, you may see some smoke-like
particles. The particles are a normal by-product of the
process that generates the non-toxic gas used for air bag
inflation. These airborne particles may irritate the skin,
eyes, nose, or throat. If you have skin or eye irritation,
rinse the area with cool water. For nose or throat
irritation, move to fresh air. If the irritation continues,
see your doctor. If these particles settle on your clothing,
follow the garment manufacturer ’s instructions for
cleaning.
Do not drive your vehicle after the air bags have deployed.
If you are involved in another collision, the air bags will
not be in place to protect you.
WARNING!
Deployed air bags and seat belt pretensioners cannot
protect you in another collision. Have the air bags, seat
belt pretensioners, and the seat belt retractor assem-
blies replaced by an authorized dealer immediately.
Also, have the Occupant Restraint Controller System
serviced as well.

STARTING THE ENGINE
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.
WARNING!
•Never leave children alone in a vehicle, or with
access to an unlocked vehicle.
• Allowing children to be in a vehicle unattended is
dangerous for a number of reasons. A child or others
could be seriously or fatally injured. Children
should be warned not to touch the parking brake,
brake pedal or the transmission gear selector.
• Do not leave the key fob in or near the vehicle (or in
a location accessible to children). A child could
operate power windows, other controls, or move the
vehicle.
Automatic Transmission
The gear selector must be in the PARK or NEUTRAL
position before you can start the engine. Press the brake
pedal before shifting to any driving gear.
NOTE: You must press the brake pedal before shifting out
of PARK.
Normal Starting
NOTE: Normal starting of either a cold or a warm engine
is obtained without pumping or pressing the accelerator
pedal.
Turn the ignition switch to the AVV (START) position and
release it when the engine starts. If the engine fails to start
within 10 seconds, turn the ignition switch to the STOP
(OFF/LOCK) position, wait 10 to 15 seconds, then repeat
the “Normal Starting” procedure.
Cold Weather Operation
To ensure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your authorized dealer) is recommended.
To prevent possible engine damage while starting at low
temperatures, this vehicle will inhibit engine cranking
when the ambient temperature is less than -31°F (-35° C)
and the oil temperature sensor reading indicates an engine
block heater has not been used. The message “plug in
engine heater” will be displayed in the instrument cluster
when the ambient temperature is below -25°F (-32° C) at
the time the engine is shut off as a reminder.

PARKSENSE REAR PARK ASSIST — IF EQUIPPED
The ParkSense system provides an audible indication of
the distance between the rear fascia/bumper and a de-
tected obstacle when backing up, e.g. during a parking
maneuver. Refer to “ParkSense Rear Park Assist System
Usage Precautions” for limitations of this system and
recommendations.
The ParkSense system is automatically activated when the
transmission is placed into REVERSE. As the distance from
an obstacle behind the vehicle decreases, the audible alert
becomes more frequent.
Interaction With Trailer Towing
The ParkSense system is automatically deactivated when a
trailer equipped by Mopar is hitched to the vehicle. The
system will be automatically activated as soon as the trailer
is removed. If it does not happen, turning the key ignition
switch to OFF and then to ON again would be needed. In
case of a non Mopar trailer hitches are mounted the sensor
deactivation cannot be guaranteed.
ParkSense Rear Park Assist Sensors
The four ParkSense sensors, located in the rear fascia/
bumper, monitor the area behind the vehicle that is within
the sensors’ field of view. The sensors can detect obstacles,in the horizontal direction, from approximately 12 inches
(30 cm) up to 55 inches (140 cm) from the center of the rear
fascia/bumper and up to 24 inches (60 cm) from the
corners of the rear fascia/bumper, depending on the loca-
tion, type and orientation of the obstacle.
If several obstacles are detected, the ParkSense system
indicates the nearest obstacle.
The minimum height of a detectable obstacle corresponds
to the maximum height of an obstacle that would clear the
underside of the vehicle during the parking maneuver.
