open or partially open positions. This is a normal occur-
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.

WARNING!
•The belt and retractor assembly must be replaced
if the seat belt assembly “automatic locking re-
tractor” feature or any other seat belt function is
not working properly when checked according to
the procedures in the Service Manual.
•Failure to replace the belt and retractor assembly
could increase the risk of injury in collisions.
Seat Belt Pretensioners
The driver and front passenger seat belts are equipped
with a pretensioning device that is designed to remove
any slack from the seat belt systems in the event of a
collision. This device improves the performance of the
seat belt by assuring that the belt is tight around the
occupant early in a collision. Pretensioners work for all
size occupants, including those in child restraints.NOTE:These devices are not a substitute for proper seat
belt placement by the occupant. The seat belt must still be
worn snugly and positioned properly.
The pretensioners are triggered by the Occupant Re-
straint Control (ORC) Module. Like the front airbags, the
pretensioners are a single use item. After a collision that
is severe enough to deploy the airbags and pretensioners,
they must be replaced.
Enhanced Seat Belt Use Reminder System
(BeltAlert)
If the driver or front passenger seat belt has not been
buckled within 60 seconds of starting the vehicle and if
the vehicle speed is greater than 5 mph (8 km/h), the
Enhanced Warning System (BeltAlert) will alert the
driver or front passenger to buckle their seat belt. The
driver should also instruct all other occupants to buckle
their seat belts. Once the warning is triggered, the
Enhanced Warning System (BeltAlert) will continue to

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 multistage inflator design. This
may allow the airbag to have different rates of inflation
that are based on collision severity and occupant size.
Also, the front passenger airbag is certified to the Federal
regulations that define Occupant Classification (Refer to
Occupant Classification Systemin this section).

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!
•Do 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 no longer functional. These
protective covers for the airbag cushions are de-
signed to open only when the airbags are inflating.
•If 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.
•If 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.
•Do not cover or place items on the airbag covers. These
items may cause serious injury during inflation.
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.
NOTE:The passenger front airbag may not deploy even
when the driver front airbag has if the Occupant Classi-
fication System (refer toOccupant Classification System
in this section) has determined the passenger seat is
empty or is occupied by someone that is classified in the
small childcategory.
44 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 deployment 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 “Child Restraint” 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.
5. If the airbag system in this vehicle needs to be
modified to accommodate a disabled person, contact the
Customer Center. Phone numbers are provided under “If
You Need Assistance” in Section 9 of this manual.WARNING!
•Relying 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.
•Being 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.
•If the vehicle has left and right side curtain
airbags, they also need room to inflate. Do not
lean against the door or window. Sit upright in the
center of the seat.

How The Airbag System Works
•
TheOccupant Restraint Control (ORC) Modulede-
termines if a frontal, side, or rollover collision is severe
enough to require the front and/or side airbags to
inflate. The front airbag inflators are designed to
provide different rates of airbag inflation from direc-
tion provided by the ORC. The ORC may also modify
the rate of inflation based on the occupant size pro-
vided by the Occupant Classification Module. The
ORC will detect roll overs, not rear impacts.
