If the front passenger seat is damaged in any way, it
should only be serviced by an authorized dealer. If the
seat is removed (or even if the seat attachment bolts are
loosened or tightened in any way), take the vehicle to an
authorized dealer.
If there is a fault present in the OCS, the “Airbag Warning
Light” (a red light located in the center of the instrument
cluster directly in front of the driver) will be turned on.
This indicates that you should take the vehicle to an
authorized dealer. The “Airbag Warning Light” is turned
on whenever there is fault that can affect the operation of
the airbag system. If there is a fault present in the OCS,
both the “PAD Indicator Light” and the “Airbag Warning
Light” are illuminated to show that the passenger airbag
is turned off until the fault is cleared. If an object is
lodged under the seat and interferes with operation of
the weight sensors, a fault will occur which turns on both
the “PAD Indicator Light” and the “Airbag WarningLight.” Once the lodged object is removed, the fault will
be automatically cleared after a short period of time.
•TheDriver and Passenger Airbag/Inflator Unitsare
located in the center of the steering wheel and the right
side of the instrument panel. When the ORC detects a
collision requiring the airbags, it signals the inflator
units. A large quantity of nontoxic gas is generated to
inflate the front airbags. Different airbag inflation rates
are possible, based on collision severity and occupant
size. The steering wheel hub trim cover and the upper
right side of the instrument panel separate and fold
out of the way as the bags inflate to their full size. The
bags fully inflate in about 50–70 milliseconds. This is
about half of the time it takes to blink your eyes. The
bags then quickly deflate while helping to restrain the
driver and front passenger.
The driver front airbag gas is vented through the vent
holes in the sides of the airbag. The passenger front
46 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
Unapproved modifications or service procedures to
the front passenger seat assembly, its related compo-
nents, or seat cover may inadvertently change the
airbag 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 an acci-
dent. A modified vehicle may not comply with
required Federal Motor Vehicle Safety Standards
(FMVSS).
If A Deployment Occurs
The airbag system is designed to deploy when the
Occupant Restraint Control (ORC) Module detects a
moderate-to-severe frontal collision, to help restrain the
driver and front passenger, and then to immediately
deflate.NOTE:A frontal collision that is not severe enough to
need airbag protection will not activate the system. This
does not mean something is wrong with the airbag
system.
If you do have a collision which deploys the airbags, any
or all of the following may occur:
•The nylon airbag material may sometimes cause abra-
sions and/or skin reddening to the driver and front
passenger as the airbags 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 airbags deflate you may see some smoke-like
particles. The particles are a normal by-product of the
process that generates the nontoxic gas used for airbag
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 instruc-
tions for cleaning.
•It is not advisable to drive your vehicle after the
airbags have deployed. If you are involved in another
collision, the airbags will not be in place to protect you.
WARNING!
Deployed airbags and seat belt pretensioners cannot
protect you in another collision. Have the airbags,
seat belt pretensioner, and seat belt retractor assem-
bly, replaced by an authorized dealer as soon as
possible. Also, have the Occupant Classification
System serviced as well.
Enhanced Accident Response Feature
If the airbags deploy after an impact and the electrical
system remains functional, vehicles equipped with
power door locks will unlock automatically. In addition,
approximately 5 seconds after the vehicle has stopped
moving, the interior lights will illuminate to aid visibility.
NOTE:The interior lights can only be deactivated if the
key is removed from the ignition switch or the vehicle is
driven.
50 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Maintaining Your Airbag System
WARNING!
•Modifications to any part of the airbag system could cause it to fail
when you need it. You could be injured if the airbag 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 or vehicle body structure.
•Do not attempt to modify any part of your advanced airbag system.
The airbag may inflate accidentally or may not function properly if
modifications are made. Take your vehicle to an authorized dealer for
any advanced airbag system service. If your seat including 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 an advanced airbag system
for persons with disabilities, contact your authorized dealer.
•Do not place or hang any items such as add-on video players on the
right front passenger seat back. The additional weight may cause
the Occupant Classification System to be unable to correctly classify
the right front occupant. This could allow the passenger frontal
airbag to inflate when it is not desired.
•You need proper knee impact protection in a collision. Do not mount
or locate any aftermarket equipment on or behind the knee bolsters.
•It is dangerous to try to repair any part of the airbag system yourself.
Be sure to tell anyone who works on your vehicle that it has an
airbag system.
Airbag Warning Light
You will want to have the airbag system ready to inflate
for your protection in an impact. 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 6 to 8 seconds after the
ignition switch is first turned on.
•Remains on after the 6 to 8 second interval.
•Comes on for any period of time while driving.
Event Data Recorder (EDR)
In the event of an airbag deployment, your vehicle is
designed to record up to 2-seconds of specific vehicle
data parameters (see list below) in an event data recorder
prior to the moment of airbag deployment. Please note
that such data are ONLY recorded if an airbag deploys,
and are otherwise unavailable. In conjunction with other

Data Parameters that May Be Recorded:
•Diagnostic trouble code(s) and warning lamp status
for electronically-controlled safety systems, including
the airbag system
•Airbag disable lamp status (if equipped)
•Timeof airbag deployment (in terms of ignition
cycles and vehicle mileage)
•Airbag deployment level (if applicable)
•Seatbelt status
•Brake status (service and parking brakes)
•Accelerator status (including vehicle speed)
•Engine control status (including engine speed)
•Cruise control status
•Traction/stability control status
Child Restraint
Everyone in your vehicle needs to be buckled up all the
time — babies and children, too. 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 and under should ride properly buck-
led 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.
There are different sizes and types of restraints for
children from newborn size to the child almost large
enough for an adult safety belt. Always check the child
seat Owner’s Manual to ensure you have the right seat
for your child. Use the restraint that is correct for your
child:
