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.
3500 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.

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.

254 SAFETY
Air Bag System Components
NOTE:
The Occupant Restraint Controller (ORC) monitors the
internal circuits and interconnecting wiring associated with
electrical Air Bag System Components listed below:
• Occupant Restraint Controller (ORC)
• Air Bag Warning Light
• Steering Wheel and Column
• Instrument Panel
• Knee Impact Bolsters
• Driver and Front Passenger Air Bags
• Seat Belt Buckle Switch
• Supplemental Side Air Bags
• Front and Side Impact Sensors — If Equipped
• Seat Belt Pretensioners
• Seat Track Position SensorsIf 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 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

SAFETY 289
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts and
cracks. Inspect sidewalls for cuts, cracks, and bulges. Check
the wheel bolts for tightness. Check the tires (including
spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight parking for
fuel, coolant, oil, or other fluid leaks. Also, if gasoline fumes
are detected or if fuel, or brake fluid leaks are suspected. The
cause should be located and corrected immediately.
• ALWAYS make sure objects cannot fall or slide into the
driver’s side floor area when the vehicle is moving.
Objects can become trapped under accelerator, brake,
or clutch pedals and could cause a loss of vehicle
control.
• NEVER place any objects under the floor mat (e.g., towels, keys, etc.). These objects could change the posi -
tion of the floor mat and may cause interference with
the accelerator, brake, or clutch pedals.
• If the vehicle carpet has been removed and re-installed, always properly attach carpet to the floor and check the
floor mat fasteners are secure to the vehicle carpet.
Fully depress each pedal to check for interference with
the accelerator, brake, or clutch pedals then re-install
the floor mats.
• It is recommended to only use mild soap and water to clean your floor mats. After cleaning, always check
your floor mat has been properly installed and is
secured to your vehicle using the floor mat fasteners by
lightly pulling mat.

Only
AutoPark is a supplemental feature to assist in placing the
vehicle in PARK should the situations on the following
pages occur. It is a back up system and should not be relied
upon as the primary method by which the driver shifts the
vehicle into PARK.
The conditions under which AutoPark will engage are
outlined on the following pages.
WARNING!

• Driver inattention could lead to failure to place the vehicle in PARK. ALWAYS DO A VISUAL CHECK that your
vehicle is in PARK by verifying that a solid (not blinking)
“P” is indicated in the Instrument Cluster Display and
near the gear selector. If the "P" indicator is blinking, your
vehicle is not in PARK. As an added precaution, always
apply the parking brake when exiting the vehicle.
