windows down, or the sunroof (if equipped) in certain
open or partially open positions. This is a normal occur-
rence and can be minimized. If the buffeting occurs with
the rear windows open, open the front and rear windows
together to minimize the buffeting. 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 front passenger, and if
equipped, left and right window bags for the driver and
passengers seated next to a window and a driver inflat-
able knee blocker. If you will be carrying children too
small for adult-size seat belts, your seat belts or the
LATCH feature (refer to the Child Restraint section in this
manual), can be used to hold infant and child restraint
systems.If your vehicle is equipped with the Occupant Classifi-
cation System (OCS) there will be a Passenger Airbag
Disabled (PAD) Indicator Light located on the center of
the instrument panel.

Seat Belt Pretensioners
The seat belts for both front seating positions are
equipped with pretensioning devices that are designed to
remove slack from the seat belt in the event of a collision.
These devices improve the performance of the seat belt
by assuring that the belt is tight about the occupant early
in a collision. Pretensioners are designed to work for all
size occupants.
NOTE:These devices are not a substitute for proper seat
belt placement by the occupant. The seat belt still must be
worn snugly and positioned properly.
The pretensioners are triggered by the front airbag con-
trol module (see Airbag Section). Like the front airbags,
the pretensioners are single use items. After a collision
that is severe enough to deploy the airbags and preten-
sioners, both must be replaced.
Enhanced Driver Seat Belt Reminder System
(BeltAlert)
If the driver’s 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 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
chime and flash the Seat Belt Warning Light for 96
seconds or until the driver’s seat belt is buckled.
The Enhanced Warning System (BeltAlert) will be reacti-
vated if the driver’s seat belt is unbuckled for more than
10 seconds and the vehicle speed is greater than 5 mph (8
km/h).
The Enhanced Warning System (BeltAlert) can be en-
abled or disabled by your authorized dealer or by
following these steps:

How The Airbag System Works
•
TheOccupant Restraint Controller (ORC)determines
if a frontal collision is severe enough to require the
airbags to inflate. Based on the level of collisionseverity, the front control module determines the
proper rate of inflation. The front airbag inflators are
designed to provide different rates of airbag inflation.
•The ORC may modify the rate of inflation based on the
occupant size provided by the Occupant Classification
Module.
•The ORC will not detect side, roll over, or rear impacts.
•The ORC monitors the readiness of the electronic parts
of the system whenever the ignition switch is in the
START or RUN positions. These include all of the
items listed above except the steering wheel and
column, instrument panel and passenger knee bol-
sters. 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 ORC turns on the AIRBAG warning
light and PAD indicator light in the center of
the instrument panel for 6 to 8 seconds for a
self-check when the ignition is first turned on.
After the self-check, the AIRBAG warning light will turn
off. The PAD indicator light will function normally (Refer
to“Passenger Airbag Disable (PAD) Indicator Light”in
this section). If the ORC detects a malfunction in any part
of the system, it turns on the AIRBAG warning light
either momentarily or continuously. A single chime will
sound if the light comes on again after initial start up.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.
•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 and
impact sensors detects a collision requiring the air-
bags, it signals the inflator units. A large quantity of
nontoxic gas is generated to inflate the front airbags.
Different airbag inflation rates may be 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

•TheKnee Impact Bolstershelp protect the knees, and
position everyone for the best interaction with the
front airbag.
•If your vehicle contains a Passenger Airbag Disable
indicator light, it will be equipped with theOccupant
Classification System (OCS).The OCS system will
classify an occupant into a size category based on
sensor readings from within the seat cushion. Occu-
pants should try to remain in a normally seated
position. If the occupant’s weight is transferred to
another object in the vehicle (i.e. feet on the dash-
board), the OCS may not be able to properly approxi-
mate occupant size. Furthermore, the occupant size
may appear to increase or decrease due to objects
hanging on the seat, other passengers pushing on the
seat, or objects lodged underneath the seat.If there is a rapid change in temperature or humidity,
the OCS may not be able to properly approximate
occupant size. If your seat including your trim cover
and cushion needs to be serviced in any way (includ-
ing removal or loosening/tightening of seat attach-
ment bolts), take the vehicle to your authorized dealer.
Only manufacturer approved seat accessories may be
used.
If there is a fault present in the system, the AIRBAG
warning light will illuminate indicating that you should
take the vehicle to an authorized dealer. In the presence
of an occupant in the passenger seat, if both the PAD
indicator light and AIRBAG warning light are illumi-
nated the airbag will be disabled.

The ORC will not allow front airbag deployment in the
event of a collision for occupants classified into the
empty or child size categories. The PAD indicator light
will illuminate indicating that the Passenger Airbag is
OFF when the OCS has determined that the occupant size
category is a child. Also, when the seat is empty or an
object that weighs less than a predetermined threshold is
placed on the seat, the light will remain OFF. (The PAD
indicator light is an amber light located on the center of
the instrument panel above the climate controls.)

For almost all sizes of properly seated adults, the airbag
will be enabled in the event of a collision. For small
teenagers and some small adults, depending on size, the
airbag may or may not be enabled in the event of a
collision. Both drivers and passengers should always use
the PAD indicator light as an indication if the front
passenger is properly positioned or not. If the PAD
indicator light comes on when an adult is in the passen-
ger seat, have the passenger re-position themselves in the
seat until the light goes out.
Remember, if the PAD indicator light is illuminated the
passenger front airbag will not inflate. For properly
installed child restraint systems and children properly
seated on the front passenger seat, the airbag will be
disabled. If at all possible, place children 12 years and
younger in a back seat.
•TheOccupant Classification Module (OCM)is lo-
cated beneath the front passenger seat. The OCMclassifies the occupant into one of three size categories
based on the input from the Bladder Assembly and
Belt Tension Sensor. The size categories include empty,
child, and adult. The OCM sends the Occupant Clas-
sification to the ORC to identify if a front passenger
airbag is allowed. If a fault is present, the AIRBAG
warning light is illuminated.
•ThePassenger Airbag Disabled (PAD) Indicator
Lightindicates to the driver and passenger when the
airbag is turned OFF in the presence of a properly
seated occupant. When the PAD indicator light is
illuminated, the airbag is OFF. Also, when the Occu-
pant Classification System (OCS) detects either an
empty seat of a weight less than the predetermined
occupant threshold, the ORC will not illuminate the
PAD indicator light even though the airbag is turned
off. When the OCS detects an adult the PAD indicator
light will be off, and the airbag will be enabled.
