Safe Driving■Front seats
The seat belt system includes an indicator on
the instrument panel to remind the driver or a
front passenger or both to fasten their seat
belts.
If you set the power mode to ON and a seat
belt is not fastened, a beeper will sound and
the indicator will blink. After a few seconds,
the beeper will stop and the indicator will
come on and remain illuminated until the seat
belt is fastened.
When the vehicle is mo ving, the beeper will
sound and the indicator will blink for a while
until the seat belt is fastened.
Then, the beeper will st op and the indicator
will stay on.
■Seat Belt Reminder1 Seat Belt Reminder
The indicator will also co me on if a front passenger
does not fasten their seat belt after the power mode
is set to ON.
When no one is sitting in th e front passenger’s seat,
the indicator will not come on and the beeper will not
sound.
The indicator also may no t come on and the beeper
may not sound when the occupant is not heavy
enough to trigger the weight sensor. Such occupants
(e.g., infants and smaller children) should be moved
to the rear seat as a deploying front airbag likely will
injure or kill them. 2 Protecting Child Passengers P. 64
The multi-information display uses colors to aid the
driver in checking the st atus of the passengers.

The front, driver’s kn ee, front passenger’s
knee, side, and side curtain airbags are
deployed according to the direction and
severity of impact. Both side curtain airbags
are deployed in a rollover. The airbag
system includes:
aTwo SRS (Supplemental Restraint System)
front airbags. The driver’s airbag is stored
in the center of the steering wheel; the
front passenger’s airbag is stored in the
dashboard. Both are marked SRS
AIRBAG.
bTwo knee airbags. The driver’s knee
airbag is stored under the steering
column; the front passenger’s knee
airbag is stored under the glove box.
Both are marked SRS AIRBAG.
cTwo side airbags, one for the driver and
one for the front passenger. The airbags
are stored in the outer edges of the seat-
backs. Both are marked SIDE AIRBAG.
dTwo side curtain airbags, one for each
side of the vehicle. The airbags are stored
in the ceiling, abov e the side windows.

Safe DrivingFront airbags are designed to inflate during moderate-to-severe frontal collisions.
When the vehicle decelerates suddenly, the sensors send information to the control
unit which signals one or both front airbags to inflate.
A frontal collision can be either head-on or angled between two vehicles, or when a
vehicle crashes into a stationary object, such as a concrete wall.
While your seat belt restrains your torso, the
front airbag provides supplemental protection
for your head and chest.
The front airbags deflate immediately so that
they won’t interfere with the driver’s visibility
or the ability to steer or operate other
controls.
The total time for inflation and deflation is so fast that most occupants are not
aware that the airbags depl oyed until they see them lying in front of them.
■Operation
■How the Front Airbags Work1How the Front Airbags Work
Although the driver’s and fr ont passenger’s airbags
normally inflate within a spli t second of each other, it
is possible for only one airbag to deploy. This can
happen if the severity of a collision is at the margin,
or threshold, that determines whether or not the
airbags will deploy. In such cases, the seat belt will
provide sufficient protec tion, and the supplemental
protection offered by the airbag would be minimal.

■When front airbags should not deploy
Minor frontal crashes: Front airbags were designed to supplement seat belts and
help save lives, not to prev ent minor scrapes, or even br oken bones that might occur
during a less than moderate-to-severe frontal crash.
Side impacts: Front airbags can provide protecti on when a sudden deceleration
causes a driver or front passenger to move toward the front of the vehicle. Side
airbags and side curtain airbags have been specifically designed to help reduce the
severity of injuries that can occur during a moderate-to-severe side impact which
can cause the driver or passenger to move toward the side of the vehicle.
Rear impacts: Head restraints and seat belts ar e your best protection during a rear
impact. Front airbags cannot provide any si gnificant protection and are not designed
to deploy in such collisions.
Rollovers: In a rollover, your best form of protection is a seat belt or, if your vehicle
is equipped with a rollover sensor, both a seat belt and a side curtain airbag. Front
airbags, however, are not designed to depl oy in a rollover as they would provide
little if any protection.
■When front airbags deploy with little or no visible damage
Because the airbag system senses sudden deceleration, a strong impact to the
vehicle framework or suspension might cause one or more of the airbags to deploy.
Examples include running into a curb, the edge of a hole, or other low fixed object
that causes a sudden deceleration in th e vehicle chassis. Since the impact is
underneath the vehicle, damage may not be readily apparent.
■When front airbags may not deploy , even though exterior damage
appears severe
Since crushable body parts absorb crash energy during an impact, the amount of
visible damage does not always indicate proper airbag operation. In fact, some
collisions can result in severe damage but no airbag deployment because the airbags
would not have been needed or would not have provided protection even if they
had deployed.

Safe DrivingThe airbags have advanced features to help reduce the likelihood of airbag related
injuries to smaller occupants.
The driver’s advanced airbag system includes a
seat position sensor.
Based on information from this sensor and the
severity of the impact, the advanced airbag
system determines the optimal deployment of
the driver’s airbag.
The front passenger’s advanced airbag system
has weight sensors. The sensors are used for
occupant classification to activate or
deactivate the front passenger’s airbag.
For adult size occupants, the system will
automatically activate the front passenger’s
airbag. If a small adul t sits in the front
passenger seat and the system does not
recognize him/her as an adult, see
2 Passenger Airbag Off Indicator P. 61
■Advanced Airbags1Advanced Airbags
If there is a problem with the driver’s seat position
sensor or the passenger’s s eat weight sensors, the
SRS indicator will come on, and in the event of a
crash, the airbag will deploy (regardless of the driver’s
seating position or passenger’s occupant
classification) with a force corresponding to the
severity of the impact. 2 Supplemental Restraint System (SRS)
Indicator P. 60
For the advanced front airbags to work properly,
confirm that:
•The occupant is sitting in an upright position,
wearing the seat belt prope rly and the seat-back is
not excessively reclined.
•The occupant is not leaning against the door or
center console.
•The occupant’s feet are plac ed on the floor in front
of them.
•There are no objects ha nging from the front
passenger’s seat.
•Only small, lightweight objects are in the seat-back
pocket.
•The steering wheel and passenger’s side dashboard
are not obstructed by any object.
•No liquid has been spille d on or under the seat.

We advise against allowing a child age 12 or under to ride in the front passenger’s
seat. However, if you do allow a small child or infant to ride in the front passenger’s
seat, the system is designed to automatically deactivate the front passenger’s airbag.
Do not let a small child or infant ride in th e front passenger’s seat if the airbag does
not automatically deactivate.1 Advanced Airbags
•There is no child seat or other object pressing
against the rear of the seat or seat-back.
•There is no rear passenger pushing or pulling on
the back of the front passenger’s seat.
•There are no objects placed under or beside the
front passenger’s seat . Improperly positioned
objects can interfere with the advanced airbag
sensors.
•The head restraint is not contacting the roof. 2Passenger Airbag Off Indicator P. 61
•The floor mat behind the front passenger’s seat is
set in the correct position evenly on the floor. An

Side Airbags
The side airbags help protect the torso and pelvis of the driver or a front passenger
during a moderate-to-severe side impact.
The side airbags are housed in the outside
edge of the driver’s and passenger’s seat-
backs.
Both are marked SIDE AIRBAG.
When the sensors detect a moderate-to-
severe side impact, the control unit signals the
side airbag on the impact side to immediately
inflate.
■Housing Locations
1 Side Airbags
Make sure you and your front seat passenger always
sit upright. Leaning into the path of a side airbag can
prevent the airbag from deploying properly and
increases your risk of serious injury.
Do not attach accessories on or near the side airbags.
They can interfere with the proper operation of the
airbags, or hurt someone if an airbag inflates.
Do not cover or replace the front seat-back covers
without consulting a dealer.
Improperly replac ing or covering front seat-back
covers can prevent your si de airbags from properly
deploying during a side impact.

Safe Driving
■When a side airbag deploys with little or no visible damage
Because the airbag system senses sudden acceleration, a strong impact to the side
of the vehicle’s framework can cause a side airbag to deploy. In such cases, there
may be little or no damage, but the side impact sensors detected a severe enough
impact to deploy the airbag.
■When a side airbag may not deploy, even though visible damage appears
severe
It is possible for a side airbag not to deploy during an impact that results in
apparently severe damage. This can occur when the point of impact was toward the
far front or rear of the vehicle, or when the vehicle’s crushable body parts absorbed
most of the crash energy. In either case , the side airbag would not have been
needed nor provided protection even if it had deployed.
