Driver And Passenger Advanced Front Air Bag
Inflator Units
The Driver 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 (if
equipped). When the ORC detects a collision requiring
the Advanced 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 the collision type and sever-
ity. 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.
Enhanced Accident Response System
In the event of an impact causing air bag deployment, if
the communication network remains intact, and the
power remains intact, depending on the nature of the
event the ORC will determine whether to have the
Enhanced Accident Response System perform the follow-
ing functions:
• Cut off fuel to the engine.
• Flash hazard lights as long as the battery has power or
until the ignition key is turned off.
• Turn on the interior lights, which remain on as long as
the battery has power or until the ignition key is
removed.
• Unlock the doors automatically. 2 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 59

In order to reset the Enhanced Accident Response System
functions after an event, the ignition switch must be
changed from IGN ON to IGN OFF.
If A Deployment Occurs
The Advanced Front Air Bags are designed to deflate
immediately after deployment.
NOTE: Front 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 nylon air bag material may sometimes cause
abrasions and/or skin reddening to the driver and
front passenger 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 in-
structions for cleaning.60 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Do not drive your vehicle after the air bags have de-
ployed. If you are involved in another collision, the air
bags will not be in place to protect you.
WARNING!Deployed air bags cannot protect you in another
collision. Have the air bags replaced by an autho-
rized dealer immediately. Also, have the Occupant
Restraint Controller (ORC) system serviced as well. Maintaining Your Air Bag System
WARNING!• Modifications to any part of the air bag system
could cause it to fail when you need it. You could
be injured if the air bag system is not there to
protect you. Do not modify the components or
wiring, including adding any kind of badges or
stickers to the steering wheel hub trim cover or the
upper right side of the instrument panel. Do not
modify the front bumper, vehicle body structure,
or add aftermarket side steps or running boards.
• It is dangerous to try to repair any part of the air
bag system yourself. Be sure to tell anyone who
works on your vehicle that it has an air bag system.

WARNING! (Continued)• Do not attempt to modify any part of your air bag
system. The air bag may inflate accidentally or
may not function properly if modifications are
made. Take your vehicle to an authorized dealer
for any air bag system service. If your seat includ-
ing your trim cover and cushion needs to be
serviced in any way (including removal or
loosening/tightening of seat attachment bolts),
take the vehicle to your authorized dealer. Only
manufacturer approved seat accessories may be
used. If it is necessary to modify the air bag system
for persons with disabilities, contact your autho-
rized dealer. Air Bag Warning Light
You will want to have the air bags ready to
inflate for your protection in a collision. The
Air Bag Warning Light monitors the internal
circuits and interconnecting wiring associated
with air bag system electrical components. 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 turned to the 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.62 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

NOTE: If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. The air bags may
not be ready to inflate for your protection. Promptly
check the fuse block for blown fuses. Refer to the label
located on the inside of the fuse block cover for the
proper air bag fuses. See your authorized dealer if the
fuse is good.
Event Data Recorder (EDR)
This vehicle is equipped with an event data recorder
(EDR). The main purpose of an EDR is to record, in
certain crash or near crash-like situations, such as an air
bag deployment or hitting a road obstacle, data that will
assist in understanding how a vehicle’s systems per-
formed. The EDR is designed to record data related to
vehicle dynamics and safety systems for a short period of
time, typically 30 seconds or less. The EDR in this vehicle
is designed to record such data as:
• How various systems in your vehicle were operating; • Whether or not the driver and passenger safety belts
were buckled/fastened;
• How far (if at all) the driver was depressing the
accelerator and/or brake pedal; and,
• How fast the vehicle was traveling.
These data can help provide a better understanding of
the circumstances in which crashes and injuries occur.
NOTE: EDR data are recorded by your vehicle only if a
non-trivial crash situation occurs; no data are recorded by
the EDR under normal driving conditions and no per-
sonal data (e.g., name, gender, age, and crash location)
are recorded. However, other parties, such as law en-
forcement, could combine the EDR data with the type of
personally identifying data routinely acquired during a
crash investigation. 2 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 63
Page 66 of 502

To read data recorded by an EDR, special equipment is
required, and access to the vehicle or the EDR is needed.
In addition to the vehicle manufacturer, other parties,
such as law enforcement, that have the special equip-
ment, can read the information if they have access to the
vehicle or the EDR.
Child Restraints
Everyone in your vehicle needs to be buckled up all the
time, including babies and children. Every state in the
United States and all Canadian provinces require that
small children ride in proper restraint systems. This is the
law, and you can be prosecuted for ignoring it.
Children 12 years or younger should ride properly
buckled up in a rear seat, if available. According to crash
statistics, children are safer when properly restrained in
the rear seats rather than in the front. WARNING!In a collision, an unrestrained child, even a tiny baby,
can become a projectile inside the vehicle. The force
required to hold even an infant on your lap can
become so great that you could not hold the child, no
matter how strong you are. The child and others
could be badly injured. Any child riding in your
vehicle should be in a proper restraint for the child’s
size.
Infants And Child Restraints
Safety experts recommend that children ride rearward-
facing in the vehicle until they are two years old or until
they reach either the height or weight limit of their rear
facing child safety seat. Two types of child restraints can
be used rearward-facing: infant carriers and convertible
child seats.64 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
Page 67 of 502

The infant carrier is only used rearward-facing in the
vehicle. It is recommended for children from birth until
they reach the weight or height limit of the infant carrier.
Convertible child seats can be used either rearward-
facing or forward-facing in the vehicle. Convertible child
seats often have a higher weight limit in the rearward-
facing direction than infant carriers do, so they can be
used rearward-facing by children who have outgrown
their infant carrier but are still less than at least two years
old. Children should remain rearward-facing until they
reach the highest weight or height allowed by their
convertible child seat. Both types of child restraints are
held in the vehicle by the lap/shoulder belt or the
LATCH child restraint anchor system. Refer to “Lower
Anchors and Tether for CHildren (LATCH)”. WARNING!Rearward-facing child seats must never be used in
the front seat of a vehicle with the front passenger air
bag. An air bag deployment could cause severe
injury or death to infants in this position.
Older Children And Child Restraints
Children who are two years old or who have outgrown
their rear-facing convertible child seat can ride forward-
facing in the vehicle. Forward-facing child seats and
convertible child seats used in the forward-facing direc-
tion are for children who are over two years old or who
have outgrown the rear-facing weight or height limit of
their rear-facing convertible child seat. Children should
remain in a forward-facing child seat with a harness for
as long as possible, up to the highest weight or height
allowed by the child seat. These child seats are also held 2 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 65
Page 68 of 502

in the vehicle by the lap/shoulder belt or the LATCH
child restraint anchorage system. Refer to “Lower An-
chors and Tether for CHildren (LATCH)”.
All children whose weight or height is above the
forward-facing limit for the child seat should use a
belt-positioning booster seat until the vehicle’s seat belts
fit properly. If the child cannot sit with knees bent over
the vehicle’s seat cushion while the child’s back is against
the seatback, they should use a belt-positioning booster
seat. The child and belt-positioning booster seat are held
in the vehicle by the lap/shoulder belt.
NOTE: For additional information, refer to
www.seatcheck.org or call 1–866–SEATCHECK. Cana-
dian residents should refer to Transport Canada’s web-
site for additional information: http://www.tc.gc.ca/
roadsafety/safedrivers/childsafety/index.htm WARNING!• Rearward-facing child seats must never be used in
the front seat of a vehicle with a front passenger
air bag. An air bag deployment could cause severe
injury or death to infants in this position.
• Improper installation can lead to failure of an
infant or child restraint. It could come loose in a
collision. The child could be badly injured or
killed. Follow the manufacturer’s directions ex-
actly when installing an infant or child restraint.
• A rearward-facing child restraint should only be
used in a rear seat.
Here are some tips for getting the most out of your child
restraint:
• Before buying any restraint system, make sure that it
has a label certifying that it meets all applicable Safety
Standards. Chrysler Group LLC also recommends that66 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
Page 69 of 502

you make sure that you can install the child restraint in
the vehicle where you will use it before you buy it.
• The restraint must be appropriate for your child’s
weight and height. Check the label on the restraint for
weight and height limits.
• Carefully follow the instructions that come with the
restraint. If you install the restraint improperly, it may
not work when you need it.
• In the rear seat, you may have trouble tightening the
lap/shoulder belt on the child restraint because the
buckle or latch plate is too close to the belt path
opening on the restraint. Disconnect the latch plate
from the buckle and twist the short buckle-end belt
several times to shorten it. Insert the latch plate into
the buckle with the release button facing out. • If the belt still can’t be tightened, or if pulling and
pushing on the restraint loosens the belt, disconnect
the latch plate from the buckle, turn the latch plate
around, and insert the latch plate into the buckle
again. If you still can’t make the child restraint secure,
try a different seating position.
• Buckle the child into the seat according to the child
restraint manufacturer’s directions.
WARNING!• Improper installation can lead to failure of an
infant or child restraint. It could come loose in a
collision. The child could be badly injured or
killed. Follow the manufacturer’s directions ex-
actly when installing an infant or child restraint.

WARNING! (Continued)• When your child restraint is not in use, secure it in
the vehicle with the seat belt or remove it from the
vehicle. Do not leave it loose in the vehicle. In a
sudden stop or accident, it could strike the occu-
pants or seatbacks and cause serious personal
injury.
Children Too Large For Booster Seats
Children who are large enough to wear the shoulder belt
comfortably, and whose legs are long enough to bend
over the front of the seat when their back is against the
seat back should use the lap/shoulder belt in a rear seat.
• Make sure that the child is upright in the seat.
• The lap portion should be low on the hips and as snug
as possible. • Check belt fit periodically. A child’s squirming or
slouching can move the belt out of position.
If the shoulder belt contacts the face or neck, move the
child closer to the center of the vehicle. Never allow a
child to put the shoulder belt under an arm or behind
their back.
Lower Anchors and Tether for CHildren (LATCH)
Each vehicle is equipped with the child restraint anchor-
age system called LATCH, which stands for Lower
Anchors and Tether for CHildren. The LATCH system
provides for the installation of the child restraint without
using the vehicle seat belt, instead securing the child
restraint using lower anchorages and upper tether straps
from the child restraint to the vehicle structure. LATCH
child restraint anchorage systems are installed in the
Quad Cab , Mega Cab and Crew Cab rear seat outboard
positions. LATCH equipped seating positions feature
both lower anchor bars, located at the back of the seat68 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
