Front Air Bags
This vehicle has front air bags and lap/shoulder belts for
both the driver and front passenger. The front air bags are a
supplement to the seat belt restraint systems. The driver
front air bag is mounted in the center of the steering wheel.
The passenger front air bag is mounted in the instrument
panel, above the glove compartment. The words “SRS
AIRBAG” or “AIRBAG” are embossed on the air bag covers.Front Air Bag/Knee Bolster Locations Driver And Passenger Front Air Bag Features
2500 Series Truck
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.

2 — Driver And Passenger Knee Impact Bolsters
WARNING!
• Being too close to the steering wheel or instrument panel during front air bag deployment could cause
serious injury, including death. Air bags need room to
inflate. Sit back, comfortably extending your arms to
reach the steering wheel or instrument panel.
• 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.
• Never install a rear-facing child restraint in the front seat of a vehicle. Only use a rear-facing child restraint in the
rear seat. If the vehicle does not have a rear seat, do not
transport a rear-facing child restraint in that vehicle.

248 SAFETY
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 Advanced
Front Air Bags.
This vehicle may be equipped with driver and/or front
passenger seat track position sensors that may adjust the
inflation rate of the Advanced Front Air Bags based upon
seat position.

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 colli -
sion 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.

SAFETY 249
Front Air Bag Operation
Front Air Bags are designed to provide additional protection
by supplementing the seat belts. Front air bags are not
expected to reduce the risk of injury in rear, side, or rollover
collisions. The front air bags will not deploy in all frontal
collisions, including some that may produce substantial
vehicle damage — for example, some pole collisions, 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 passenger
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 occupants 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 Side Air Bags
Supplemental Seat-Mounted Side Air Bags (SABs)
This vehicle is equipped with Supplemental Seat-Mounted
Side Air Bags (SABs).
Supplemental Seat-Mounted Side Air Bags (SABs) are
located in the outboard side of the front seats. The SABs are
marked with “SRS AIRBAG” or “AIRBAG” on a label or on
the seat trim on the outboard side of the seats.
The SABs may help to reduce the risk of occupant injury
during certain side impacts, in addition to the injury reduc-
tion potential provided by the seat belts and body structure. Supplemental Seat-Mounted Side Air Bag Label
When the SAB deploys, it opens the seam on the outboard
side of the seatback’s trim cover. The inflating SAB deploys
through the seat seam into the space between the occupant
and the door. The SAB moves at a very high speed and with
such a high force that it could injure occupants if they are not
seated properly, or if items are positioned in the area where
the SAB inflates. Children are at an even greater risk of injury
from a deploying air bag.

SAFETY 251
Supplemental Side Air Bag Inflatable Curtains (SABICs)
This vehicle is equipped with Supplemental Side Air Bag
Inflatable Curtains (SABICs).
Supplemental Side Air Bag Inflatable Curtains (SABICs) are
located above the side windows. The trim covering the
SABICs is labeled “SRS AIRBAG” or “AIRBAG.”Supplemental Side Air Bag Inflatable Curtain (SABIC)
Label Location
SABICs may help reduce the risk of head and other injuries
to front and rear seat outboard occupants in certain side
impacts, in addition to the injury reduction potential
provided by the seat belts and body structure.
The SABIC deploys downward, covering the side windows.
An inflating SABIC pushes the outside edge of the headliner
out of the way and covers the window. The SABICs inflate
with enough force to injure occupants if they are not belted
and seated properly, or if items are positioned in the area
where the SABICs inflate. Children are at an even greater
risk of injury from a deploying air bag.
WARNING!
Do not use accessory seat covers or place objects between
you and the Side Air Bags; the performance could be
adversely affected and/or objects could be pushed into
you, causing serious injury.

252 SAFETY
(Continued)
The SABICs may help reduce the risk of partial or complete
ejection of vehicle occupants through side windows in
certain side impact events.
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 severity
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!
• Do not mount equipment, or stack luggage or other cargo up high enough to block the deployment of the
SABICs. The trim covering above the side windows
where the SABIC and its deployment path are located
should remain free from any obstructions.
• In order for the SABICs to work as intended, do not install any accessory items in your vehicle which could
alter the roof. Do not add an aftermarket sunroof to
your vehicle. Do not add roof racks that require perma -
nent attachments (bolts or screws) for installation on
the vehicle roof. Do not drill into the roof of the vehicle
for any reason.
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 windows, or area
where the side air bags inflate, even if they are in an
infant or child restraint.

SAFETY 253
NOTE:
Air bag covers may not be obvious in the interior trim, but
they will open during air bag deployment.Rollover Events
Side Air Bags are designed to activate in certain rollover
events. The Occupant Restraint Controller (ORC) determines
whether the deployment of the Side Air Bags in a particular
rollover event is appropriate, based on the severity and type
of collision. 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 rollover events. The
rollover sensing system determines if a rollover event may
be in progress and whether deployment is appropriate. In
the event the vehicle experiences a rollover or near rollover
event, and deployment of the Side Air Bags is appropriate,
the rollover sensing system will also deploy the seat belt
pretensioners on both sides of the vehicle.
The SABICs may help reduce the risk of partial or complete
ejection of vehicle occupants through side windows in
certain rollover or side impact events.
• 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 restrained in a child restraint or
booster seat that is appropriate for the size of the child.
WARNING!
• Side Air Bags need room to inflate. Do not lean against the door or window. Sit upright in the center of the seat.
• Being too close to the Side Air Bags during deployment could cause you to be severely injured or killed.
• Relying on the Side Air Bags alone could lead to more severe injuries in a collision. The Side Air Bags work with
your seat belt to restrain you properly. In some collisions,
Side Air Bags won’t deploy at all. Always wear your seat
belt even though you have Side Air Bags.

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 gymna -
sium 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 imme -
diately.
• As the air bags deflate, you may see some smoke-like parti -
cles. 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
