Driver and Passenger Advanced Front Airbag
Inflator Units
TheDriver and Passenger Advanced Front Airbag In-
flator Units are located in the center of the steering wheel
and the right side of the instrument panel. When the
ORC detects a collision requiring the Advanced Front
Airbags, it signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the Advanced Front
Airbags. Different airbag inflation rates are possible
based on collision severity and type. The steering wheel
hub trim cover and the upper right side of the instrument
panel separate and fold out of the way as the airbags
inflate to their full size. The airbags fully inflate in about
50 to 70 milliseconds. This is about half of the time it
takes to blink your eyes. The airbags then quickly deflate
while helping to restrain the driver and front passenger. The Advanced Front Airbag gas is vented through the
vent holes in the sides of the airbag. In this way, the
airbags do not interfere with your control of the vehicle.
Along with seat belts and pretensioners, Advanced Front
Airbags work with the knee bolsters to provide improved
protection for the driver and front passenger. Side airbags
also work with seat belts to improve occupant protection.
Supplemental Side Airbag Inflatable Curtains
(SABIC)
The
Supplemental Side Airbag Inflatable Curtains
(SABIC) may deploy during rollovers and collisions
where the impact is confined to a particular area of the
side of the vehicle, depending on the severity and type of
collision. In these events, the ORC will deploy the SABIC
only on the impact side of the vehicle. Because airbag
sensors estimate deceleration over time, vehicle speed
and damage by themselves are not good indicators of
whether or not an airbag should have deployed.
68 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

A quantity of non-toxic gas is generated to inflate the side
curtain airbag. The inflating side curtain airbag pushes
the outside edge of the headliner out of the way and
covers the window. The airbag inflates in about 30
milliseconds (about one quarter of the time it takes to
blink your eyes) with enough force to injure you if you
are not belted and seated properly, or if items are
positioned in the area where the side curtain airbag
inflates. This especially applies to children. The side
curtain airbag is only about 3
12inches (9 cm) thick when
it is inflated.
The system includes side impact sensors adjacent to both
front and rear seat occupants that are calibrated to deploy
the SABIC airbags during impacts that require airbag
occupant protection.
WARNING!
If your vehicle is equipped with left and right
Supplemental Side Airbag Inflatable Curtains
(SABIC), do not stack luggage or other cargo up high
enough to block the location of the SABIC. The area
where the SABIC is located should remain free from
any obstructions.
The front passenger seat assembly contains critical com-
ponents that affect the front passenger airbag deploy-
ment. Correctly functioning front passenger seat compo-
nents are critical for the Occupant Classification System
(OCS) to properly classify the front passenger and calcu-
late the proper airbag deployment. Do not make any
modifications to the front passenger seat components,
assembly, or to the seat cover.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 69

Airbag Warning Light
You will want to have the airbag system ready to inflate
for your protection in an impact. The airbag warning
light monitors the internal circuits and interconnecting
wiring associated with airbag system electrical compo-
nents. The airbag system is designed to be maintenance
free. If any of the following occurs, have an authorized
dealer service the system promptly:
•Does not come on during the four to eight seconds
after the ignition switch is first turned ON.
•Remains on after the four to eight second interval.
•Comes on for any period of time while driving.
Event Data Recorder (EDR)
In the event of a collision, your vehicle is designed to
record up to five seconds of specific vehicle data param-
eters (see list below) in an event data recorder prior to the
moment of airbag deployment, or near deployment (ifapplicable), and up to a quarter second of either high-
speed deceleration data or change in velocity during
and/or after airbag deployment or near-deployment.
EDR data is ONLY recorded if an airbag deploys, or
nearly deploys, and is otherwise unavailable.
NOTE:
1. A near-deployment event occurs when the airbag
sensor detects severe vehicle deceleration usually indica-
tive of a crash, but not severe enough to warrant airbag
deployment.
2. Under certain circumstances, EDR data may not be
recorded (e.g., loss of battery power).
In conjunction with other data gathered during a com-
plete accident investigation, the electronic data may be
used by Chrysler Group LLC and others to learn more
about the possible causes of crashes and associated
injuries in order to assess and improve vehicle perfor-
mance. In addition to crash investigations initiated by

System Usage Precautions
NOTE:
•Ensure that the rear bumper is free of snow, ice, mud,
dirt and debris to keep ParkSenseoperating properly.
•Jackhammers, large trucks, and other vibrations could
affect the performance of ParkSense.
•When you turn ParkSenseoff, the instrument cluster
will display “PARK ASSIST DISABLED.” Further-
more, once you turn ParkSense off, it remains off
until you turn it on again, even if you cycle the ignition
key.
•When you move the shift lever to the REVERSE
position and ParkSense is turned off, a single chime
will sound once per ignition cycle and the instrument
cluster will display “PARK ASSIST DISABLED.”
•ParkSense, when on, will MUTE the radio when it is
sounding a tone.
•If a ParkSense system malfunction occurs, a single
chime will sound once per ignition cycle. In addition,
the Electronic Vehicle Information Center (EVIC) will
display “SERVICE PARK ASSIST SYSTEM” and the
LED in the ParkSense Rear Park Assist switch will
illuminate. If this occurs after making sure the rear
bumper is free of snow, ice, mud, dirt and debris, see
your authorized dealer for service.
CAUTION!
•ParkSense is only a parking aid and it is unable
to recognize every obstacle, including small ob-
stacles. Parking curbs might be temporarily de-
tected or not detected at all. Obstacles located
above or below the sensors will not be detected
when they are in close proximity.

CAUTION! (Continued)
•The vehicle must be driven slowly when using
ParkSenseto be able to stop in time when the
obstacle is detected. It is recommended that the
driver looks over his/her shoulder when using
ParkSense.
•Clean the ParkSense sensors with water, car wash
soap, and a soft cloth. Do not use rough or hard
cloths. Do not scratch or poke the sensors. Other-
wise, you could damage the sensors.
WARNING!
•Drivers must be careful when backing up even
when using the ParkSense Rear Park Assist Sys-
tem. Always check carefully behind your vehicle,
look behind you, and be sure to check for pedes-
trians, animals, other vehicles, obstructions, and
blind spots before backing up. You are responsible
for safety and must continue to pay attention to
your surroundings. Failure to do so can result in
serious injury or death.

WARNING! (Continued)
•Before using the ParkSenseRear Park Assist
System, it is strongly recommended that the ball
mount and hitch ball assembly is disconnected
from the vehicle when the vehicle is not used for
towing. Failure to do so can result in injury or
damage to vehicles or obstacles because the hitch
ball will be much closer to the obstacle than the
rear fascia when the warning display turns the red
LEDs ON. Also, the sensors could detect the ball
mount and hitch ball assembly, depending on its
size and shape, giving a false indication that an
obstacle is behind the vehicle.
Enabling and Disabling ParkSense
There are times when you may want to disable Park-
Sense, such as when towing a trailer.
Vehicles Equipped With the Electronic Vehicle
Information Center (EVIC)
You can turn ParkSense on or off through the EVIC.
Refer to “Electronic Vehicle Information Center (EVIC)/
Personal Settings (Customer-Programmable Features)” in
“Understanding Your Instrument Panel” for further
information.
Vehicles Equipped with ParkSense Rear Park
Assist Switch
You can turn ParkSense on or off by pressing
the ParkSense Rear Park Assist switch located
on the lower switch bank below the climate
controls.

ParkSenseOperation
ParkSenseuses four sensors located in the rear bumper
fascia to scan for obstacles up to 79 in (200 cm) away from
the rear bumper fascia. The warning display located
above the rear window provides both visible and audible
warnings to indicate the range of the object. The warning display contains two sets of yellow and red
LEDs, one set to warn of obstacles behind the left rear of
the vehicle and the other set to warn of obstacles behind
the right rear of the vehicle. The driver can view the LEDs
either through the rear view mirror or by looking at the
display above the rear window.
When the ignition is turned to the ON position, and the
system is enabled, the warning display will turn on all of
its LEDs for approximately one second. Then, the system
dimly illuminates the two inner most LEDs when it is
detecting no obstacles.
ParkSense
is active when the ignition is in the ON
position, and the system is enabled, and the driver shifts
the transmission into the REVERSE position, and the
vehicle speed is less than 11 mph (18 km/h). The
following chart shows the warning display operation
when the system is detecting an obstacle:

CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can, or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
26. Odometer / Trip Odometer Display Area
The odometer shows the total distance the vehicle has
been driven. The trip odometer shows individual trip
mileage. Refer to “Trip Odometer Button” for additional
information. NOTE:
U.S. Federal regulations require that upon trans-
fer of vehicle ownership, the seller certify to the pur-
chaser the correct mileage that the vehicle has been
driven. If your odometer needs to be repaired or serviced,
the repair technician should leave the odometer reading
the same as it was before the repair or service. If s/he
cannot do so, then the odometer must be set at zero, and
a sticker must be placed in the door jamb stating what the
mileage was before the repair or service. It is a good idea
for you to make a record of the odometer reading before
the repair/service, so that you can be sure that it is
properly reset, or that the door jamb sticker is accurate if
the odometer must be reset at zero.

•Magnetic materials should be kept away from the top
of the right rear quarter window. This is where the
compass sensor is located.
To Set the Variance
Start the engine and leave the transmission gear selector
lever in the PARK position. Press and hold the CMTCreset button (for approximately ten seconds) until the
current variance zone number is displayed. To change the
zone, press and release the CMTC reset button to increase
the variance one step. Repeat as necessary until the
desired variance is achieved.
NOTE:
The factory default zone is 8. During program-
ming, the zone value will wrap around from zone 15 to
zone 1.
Manual Compass Calibration
If the compass appears erratic inaccurate or abnormal,
you may wish to calibrate the compass. Prior to calibrat-
ing the compass, make sure the proper zone is selected.
1. Start the engine and leave the transmission in the
PARK position.
2. Press and hold the CMTC reset button (for approxi-
mately 10 seconds) until the current variance zone num-
ber is displayed.

5. Complete one or more 360–degree turns (in an area
free from large metal or metallic objects) until the CAL
indicator turns off. The compass will now function
normally.
Compass Variance
Compass Variance is the difference between Magnetic
North and Geographic North. To compensate for the
differences, the variance should be set for the zone where
the vehicle is driven, per the zone map. Once properly
set, the compass will automatically compensate for the
differences and provide the most accurate compass head-
ing.
NOTE:Magnetic materials should be kept away from
the top of the right rear quarter window. This is where
the compass sensor is located. 1. Turn the ignition switch ON.
2. Press and hold the COMPASS button for approxi-
mately two seconds.
