Enhanced Seat Belt Use Reminder System
(BeltAlert®)
BeltAlert® is a feature intended to remind the driver and
front passenger (if equipped with front passenger
BeltAlert®) to fasten their seat belts. The feature is active
whenever the ignition is on. If the driver or front seat
passenger is unbelted, the Seat Belt Reminder Light will
turn on and remain on until both front seat belts are
fastened.
The BeltAlert® warning sequence begins after the vehicle
speed is over 5 mph (8 km/h), by blinking the Seat Belt
Reminder Light and sounding an intermittent chime.
Once the sequence starts, it will continue for the entire
duration or until the respective seatbelts are fastened.
After the sequence completes, the Seat Belt Reminder

hand, depending on the type and location of impact,
Advanced Front Air Bags and Supplemental Driver Side
Knee Air Bag may deploy in crashes with little vehicle
front-end damage but that produce a severe initial decel-
eration.
The side air bags will not deploy in all side collisions.
Side air bag deployment will depend on the severity and
type of collision.
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 colli-
sions, and also are needed to help keep you in position,
away from an inflating air bag.
The ORC monitors the readiness of the electronic parts of
the air bag system whenever the ignition switch is in theSTART or ON/RUN position. If the key is in the OFF
position, in the ACC position, or not in the ignition, the
air bag system is not on and the air bags will not inflate.
The ORC contains a backup power supply system that
may deploy the air bags even if the battery loses power or
it becomes disconnected prior to deployment.
Also, the ORC turns on the Air Bag Warning
Light in the instrument panel for approxi-
mately four to eight seconds for a self-check
when the ignition is first turned on. After the
self-check, the Air Bag Warning Light will turn off. If the
ORC detects a malfunction in any part of the system, it
turns on the Air Bag Warning Light, either momentarily
or continuously. A single chime will sound if the light
comes on again after initial startup.
It also includes diagnostics that will illuminate the instru-
ment cluster Air Bag Warning Light if a malfunction is

noted that could affect the air bag system. The diagnos-
tics also record the nature of the malfunction.
WARNING!
Ignoring the Air Bag Warning Light in your instru-
ment panel could mean you won’t have the air bags
to protect you in a collision. If the light does not come
on as a bulb check when the ignition is first turned
on, stays on after you start the vehicle, or if it comes
on as you drive, have an authorized dealer service the
air bag system immediately.
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.
When the ORC detects a collision requiring the Ad-
vanced Front Air Bags, it signals the inflator units. A largequantity of non-toxic gas is generated to inflate the
Advanced Front Air Bags. Different air bag inflation rates
are possible, based on several factors, including the
collision type and severity. 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.
Supplemental Seat-Mounted Side Air Bag (SAB)
Inflator Units
The Supplemental Seat-Mounted Side Air Bags are de-
signed to activate only in certain side collisions.

enough force to injure you if you are not belted and
seated properly, or if items are positioned in the area
where the SABIC inflates. This especially applies to
children. The SABIC is only about 3-1/2 in (9 cm) thick
when it is inflated.
Because air bag sensors estimate deceleration over time,
vehicle speed and damage are not good indicators of
whether or not an air bag should have deployed.
NOTE:In a rollover the pretensioners and/or SAB and
SABIC air bags, and driver/passenger knee air bags may
deploy on both sides of the vehicle.
Front And Side Impact Sensors
In front and side impacts, impact sensors can aid the
ORC in determining appropriate response to impact
events.
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 77

In order to reset the Enhanced Accident Response System
functions after an event, the ignition switch must be
changed from IGN ON/RUN to IGN OFF.
If A Deployment Occurs
The Advanced 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 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.
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.
78 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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, 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 the air bag system for persons with dis-
abilities, contact your authorized 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 is first
cycled to the ON/RUN.
• 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.
80 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Safety Checks You Should Make Inside The
Vehicle
Seat Belts
Inspect the seat belt system periodically, checking for
cuts, frays, and loose parts. Damaged parts must be
replaced immediately. Do not disassemble or modify the
system.
Front seat belt assemblies must be replaced after a
collision. Rear seat belt assemblies must be replaced after
a collision if they have been damaged (i.e., bent retractor,
torn webbing, etc.). If there is any question regarding seat
belt or retractor condition, replace the seat belt.
Air Bag Warning Light
The light should come on and remain on for
four to eight seconds as a bulb check when the
ignition switch is first turned ON. If the light isnot lit during starting, see your authorized dealer. If the
light stays on, flickers, or comes on while driving, have
the system checked by an authorized dealer.
Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield. See your
authorized dealer for service if your defroster is inoper-
able.
Floor Mat Safety Information
Always use floor mats designed to fit the footwell of your
vehicle. Use only floor mats that leave the pedal area
unobstructed and that are firmly secured so that they
cannot slip out of position and interfere with the pedals
or impair safe operation of your vehicle in other ways.
