rence and can be minimized. If the buffeting occurs with
the sunroof open, adjust the sunroof opening to minimize
the buffeting.
OCCUPANT RESTRAINTS
Some of the most important safety features in your
vehicle are the restraint systems. These include the front
and rear seat belts for the driver and all passengers, front
airbags for both the driver and right front passenger, and,
if equipped, window bags for the driver and passengers
seated next to a window. If you will be carrying children
too small for adult-size belts, your seat belts also can be
used to hold infant and child restraint systems.
NOTE:The front airbags have a multi stage inflator
design. This allows the airbag to have different rates of
inflation that are based on collision severity.Please pay close attention to the information in this
section. It tells you how to use your restraint system
properly to keep you and your passengers as safe as
possible.WARNING!
In a collision, you and your passengers can suffer
injuries, including fatalities, if you are not properly
buckled up. You can strike the interior of your
vehicle or other passengers, or you can be thrown out
of the vehicle. Always be sure you and others in your
vehicle are buckled up properly.
Buckle up even though you are an excellent driver, even
on short trips. Someone on the road may be a poor driver
and cause a collision which includes you. This can
happen far away from home or on your own street.

Seat Belt Extender
If a seat belt is too short, even when fully extended and
when the adjustable upper shoulder belt anchorage (if
equipped) is in its lowest position, your authorized
dealer can provide you with a seat belt extender. This
extender should be used only if the existing belt is not
long enough. When it is not required, remove the ex-
tender and store it.
WARNING!
Using a seat belt extender when not needed can
increase the risk of injury in a collision. Only use
when the lap belt is not long enough when it is worn
low and snug, and in the recommended seating
positions. Remove and store the extender when not
needed.
Driver And Front Passenger Supplemental
Restraint Systems (SRS)
This vehicle has airbags for both the driver and right
front passenger as a supplement to the seat belt restraint
systems. The driver's front airbag is mounted in the
steering wheel. The passenger side airbag is mounted in

the instrument panel, above the glove compartment. The
words SRS/AIRBAG are embossed on the airbag covers.
NOTE:The front airbags are certified to the Federal
regulations that allow less forceful deployment.
The front airbags have a multi stage inflator design. This
allows the airbag to have different rates of inflation that
are based on collision severity.
This vehicle may also be equipped with window bags to
protect the driver, front, and rear passengers sitting next
to a window. If the vehicle is equipped with window
bags, they are located above the side windows. Their
covers are also labeled SRS/AIRBAG.NOTE:Airbag covers may not be obvious in the interior
trim; but they will open to allow airbag deployment.

WARNING!
²Do not put anything on or around the front airbag
covers or attempt to manually open them. You may
damage the airbags and you could be injured be-
cause the airbags are not there to protect you. These
protective covers for the airbag cushions are de-
signed to open only when the airbags are inflating.
²If your vehicle is equipped with window bags, do
not stack luggage or other cargo up high enough to
block the location of the window bag. The area
where the window bag is located should remain
free from any obstructions.
²If your vehicle is equipped with window bags, do
not have any accessory items installed which will
alter the roof, including adding a 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.
²Do not cover or place items on the airbag covers.
These items may cause serious injury during infla-
tion.
The front airbags have a multi stage inflator design. This
allows the airbag to have different rates of inflation that
are based on collision severity. Along with the seat belts,
front airbags work with the instrument panel knee bol-
sters to provide improved protection for the driver and
front passenger. Window bags also work with seat belts
to improve occupant protection.
The seat belts are designed to protect you in many types
of collisions. The front airbags deploy in moderate to
severe frontal collisions. If your vehicle is so equipped,
the window bag on the crash side of the vehicle is
triggered in moderate to severe side collisions. In certain
types of collisions, both the front and side airbags may be
triggered. But even in collisions where the airbags work,
you need the seat belts to keep you in the right position
for the airbags to protect you properly.
Here are some simple steps you can take to minimize the
risk of harm from a deploying airbag.

1. Children 12 years and under should always ride
buckled up in a rear seat.
Infants in rear facing child restraints shouldNEVERride
in the front seat of a vehicle with a passenger airbag. An
airbag deplyment could cause severe injury or death to
infants in that position.
Children that are not big enough to properly wear the
vehicle seat belt should be secured in the rear seat, in a
child restraint or belt-positioning booster seat. Older
children who do not use child restraints or belt-
positioning booster seats should ride properly buckled
up in the rear seat. Never allow children to slide the
shoulder belt behind them or under their arm.
If a child from 1 to 12 years old must ride in the front
passenger seat because the vehicle is crowded, move the
seat as far back as possible, and use the proper child
restraint. See ªChild Restraintº in this section.You should read the instructions provided with your
child restraint to make sure that you are using it properly.
2. All occupants should use their lap and shoulder belts
properly.
3. The driver and front passenger seats should be moved
back as far as practical to allow the front airbags room to
inflate.
4. If your vehicle has window bags, do not lean against
the door or window, airbags will inflate forcefully into
the space between you and the door.

WARNING!
²Relying on the airbags alone could lead to more
severe injuries in a collision. The airbags work
with your seat belt to restrain you properly. In
some collisions the airbags won't deploy at all.
Always wear your seat belts even though you
have airbags.
²Being too close to the steering wheel or instru-
ment panel during airbag deployment could cause
serious injury. Airbags need room to inflate. Sit
back, comfortably extending your arms to reach
the steering wheel or instrument panel.
²If the vehicle has window bags, they also need
room to inflate. Do not lean against the door or
window. Sit upright in the center of the seat.
Airbag System Components
The airbag system consists of the following:
²Airbag Control Module (ACM)
²Airbag Warning Light
²Driver Airbag
²Passenger Airbag
²Window Bags above Side Windows (If Equipped)
²Side Impact Sensors (If Equipped)
²Steering Wheel and Column
²Instrument Panel
²Crash Sensor
²Interconnecting Wiring

How The Airbag System Works
²
TheAirbag Control Module (ACM)determines if a
frontal collision is severe enough to require the airbags
to inflate. Based on the level of collision severity, the
front control module determines the proper rate of
inflation. The front airbag inflators are designed to
provide different rates of airbag inflation.
²The ACM, along with the remote side impact sensors
detects side impact.
²The ACM will not detect roll over, or rear impacts.
²The ACM monitors the readiness of the electronic
parts of the system whenever the ignition switch is in
the START or ON positions. These include all of the
items listed above except the steering wheel and
column and the knee bolsters. If the key is in the OFF
position, in the ACC position, or not in the ignition,
the airbags are not on and will not inflate.Also, the ACM turns on the AIRBAG warning light in
the instrument panel for 6 to 8 seconds when the
ignition is first turned on, then turns the light off. If it
detects a malfunction in any part of the system, it turns
on the light either momentarily or continuously.
WARNING!
Ignoring the AIRBAG warning light in your instru-
ment panel could mean you won't have the airbags
to protect you in a collision. If the light does not
come on, stays on after you start the vehicle, or if it
comes on as you drive, have the airbag system
checked right away.
²TheDriver and Passenger Airbag/Inflator Unitsare
located in the center of the steering wheel and the right
side of the instrument panel. When the ACM 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, these rates are determined by the front
airbag control module based on collision 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 bags inflate to their full size. The bags fully
inflate in about 30±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
airbag material towards the instrument panel. The
passenger front airbag gas is vented through the
airbag material on the sides of the airbag. In this way,
the airbags do not interfere with your control of the
vehicle.²TheSide Impact SRS Window Bagsare designed to
activate only in certain side collisions. When the airbag
control module (ACM), along with the remote side
impact sensors detects a side impact collision requir-
ing the window bags to inflate, it signals the inflators
on the crash side of the vehicle. A quantity of nontoxic
gas is generated to inflate the window bag. The
inflating window bag pushes the outside edge of the
headliner out of the way and covers the window. The
airbag inflates in about 30 milliseconds (about one
quarter of the time it takes to blink your eyes) with
enough force to injure you if you are not belted and
seated properly, or if items are positioned in the area
where the window bag inflates. This especially applies
to children. The window bag is only about 3
1¤2inches
(9 cm) thick when it is inflated.
²TheKnee Impact Bolstershelp protect the knees of
the driver and the front passenger's, and position
everyone for the best interaction with the front airbag.
