Driver And Passenger Advanced Front Air Bag
Inflator Units
TheDriver And Passenger Advanced Front Air Bag
Inflator Units are located in the center of the steering
wheel and on the right side of the instrument panel.
When the ORC detects a collision requiring the Ad-
vanced Front Air Bags, it signals the inflator units. A large
quantity of non-toxic gas is generated to inflate the
Advanced Front Air Bags. Different air bag 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 air bags inflate to their full size. The air bags fully
inflate in about 50 to 70 milliseconds. This is about half of
the time it takes to blink your eyes. The air bags then
quickly deflate while helping to restrain the driver and
front passenger. The Advanced Front Air Bag gas is vented through the
vent holes in the sides of the air bag. In this way, the air
bags do not interfere with your control of the vehicle.
Along with seat belts and pretensioners, Advanced Front
Air Bags work with the knee bolsters to provide im-
proved protection for the driver and front passenger. Side
air bags also work with seat belts to improve occupant
protection.
Supplemental Side Air Bag Inflatable Curtains
(SABIC)
The
Supplemental Side Air Bag 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 air bag
sensors estimate deceleration over time, vehicle speed

and damage by themselves are not good indicators of
whether or not an air bag should have deployed.
A quantity of non-toxic gas is generated to inflate the side
curtain air bag. The inflating side curtain air bag pushes
the outside edge of the headliner out of the way and
covers the window. The air bag 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 air bag
inflates. This especially applies to children. The side
curtain air bag is only about 3
12inches (9 cm) thick when
it is inflated.
The system includes side impact sensors that are cali-
brated to deploy the side air bags during impacts that
require air bag occupant protection.
WARNING!
If your vehicle is equipped with left and right
Supplemental Side Air Bag 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 air bag 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 air bag 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 71

The following requirements must be strictly adhered to:
•Do not modify the front passenger seat assembly or
components in any way.
•Do not use prior or future model year seat covers not
designated for the specific model being repaired. Al-
ways use the correct seat cover specified for the
vehicle.
•Do not replace the seat cover with an aftermarket seat
cover.
•Do not add a secondary seat cover other than those
approved by Chrysler Group LLC/Mopar.
•At no time should any Supplemental Restraint System
(SRS) component or SRS related component or fas-
tener be modified or replaced with any part except
those which are approved by Chrysler Group
LLC/Mopar.
WARNING!
Unapproved modifications or service procedures to
the front passenger seat assembly, its related compo-
nents or seat cover may inadvertently change the air
bag deployment in case of a frontal crash. This could
result in death or serious injury to the front seat
passenger if the vehicle is involved in a collision. A
modified vehicle may not comply with required
Federal Motor Vehicle Safety Standards (FMVSS)
and/or Canadian Motor Vehicle Safety Standards
(CMVSS).
Front And Side Impact Sensors
In front and side impacts, impact sensors can aid the
ORC in determining appropriate response to impact
events.

PARKSENSEREAR PARK ASSIST —
IF EQUIPPED
The ParkSense Rear Park Assist system provides visual
and audible indications of the distance between the rear
fascia and a detected obstacle when backing up, e.g.
during a parking maneuver. Refer to ParkSense System
Usage Precautions for limitations of this system and
recommendations.
ParkSense will retain the last system state (enabled or
disabled) from the last ignition cycle when the ignition is
changed to the ON/RUN position.
ParkSense can be active only when the shift lever is in
REVERSE. If ParkSense is enabled at this shift lever
position, the system will remain active until the vehicle
speed is increased to approximately 11 mph (18 km/h) or
above. The system will become active again if the vehicle
speed is decreased to speeds less than approximately
10 mph (16 km/h).
ParkSense 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 from approximately 12 in (30 cm) up to 79 in
(200 cm) from the rear fascia/bumper in the horizontal
direction, depending on the location, type and orienta-
tion of the obstacle.
ParkSense Warning Display
The ParkSense Warning screen will only be displayed if
Sound and Display is selected from the Customer- Pro-
grammable Features section of the Electronic Vehicle
Information Center (EVIC). Refer to “Electronic Vehicle
Information Center (EVIC)/Personal Settings (Customer-
Programmable Features)” in “Understanding Your In-
strument Panel” for further information.

Cleaning The ParkSenseSystem
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. Otherwise, you could dam-
age the sensors.
ParkSense System Usage Precautions
NOTE:
•Ensure that the rear bumper is free of snow, ice, mud,
dirt and debris to keep the ParkSense system operat-
ing properly.
•Jackhammers, large trucks, and other vibrations could
affect the performance of ParkSense.
•When you turn ParkSense off, the instrument cluster
will display “PARK ASSIST OFF.” Furthermore, 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, the instrument
cluster will display “PARK ASSIST OFF” message for
as long as the vehicle is in REVERSE.
•ParkSense, when on, will MUTE the radio when it is
sounding a tone.
•Clean the ParkSense sensors regularly, taking care
not to scratch or damage them. The sensors must not
be covered with ice, snow, slush, mud, dirt or debris.
Failure to do so can result in the system not working
properly. The ParkSense system might not detect an
obstacle behind the fascia/bumper, or it could provide
a false indication that an obstacle is behind the fascia/
bumper.
•Objects such as bicycle carriers, trailer hitches, etc.,
must not be placed within 12 in (30 cm) from the rear
fascia/bumper while driving the vehicle. Failure to do
so can result in the system misinterpreting a close
