the instrument panel to remind the driver or a
front passenger or both to fasten their seat
belts. If the ignition switch is turned to ON
(w*1 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.
The beeper will periodically sound and the
indicator will blink while the vehicle is moving
until the seat belt is fastened.

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.

uuSeat Belts uAbout Your Seat Belts
Safe DrivingThe front seats are equipped with automatic seat belt tensioners to enhance safety.
The tensioners automatically tighten the front seat belts during a moderate-to-
severe frontal collision, sometimes even if the collision is not severe enough to
inflate the front airbags.
■Automatic Seat Belt Tensioners1 Automatic Seat Belt Tensioners
The seat belt tensioners can only operate once.
If a tensioner is activated, the SRS indicator will come
on. Have a dealer replace the tensioner and
thoroughly inspect the seat belt system as it may not
offer protection in a subsequent crash.
During a moderate-to-severe side impact, the
tensioner on that side of the vehicle also activates.

Safe DrivingAirbags can pose serious hazards. To do their job, airbags must inflate with
tremendous force. So, while airbags help save lives, they can cause burns, bruises,
and other minor injuries, sometimes even fatal ones if occupants are not wearing
their seat belts properly and sitting correctly.
What you should do: Always wear your seat belt properly, and sit upright and as
far back from the steering wheel as possi ble while allowing full control of the
vehicle. A front passenger should move their seat as far back from the dashboard as
possible.
Remember, however, that no safety system can prevent all injuries or deaths that
can occur in a severe crash, even when seat belts are properly worn and the airbags
deploy.
Do not place hard or sharp objects between yourself and a front airbag.
Carrying hard or sharp objects on your lap, or driving with a pipe or other sharp
object in your mouth, can result in in juries if your front airbag inflates.
Do not attach or place object s on the front airbag covers. Objects on the
covers marked SRS AIRBAG could interfere with the proper operation of the airbags
or be propelled inside the vehicle an d hurt someone if the airbags inflate.
■Important Facts About Your Airbags1Important Facts About Your Airbags
Do not attempt to deactivate your airbags. Together,
airbags and seat belts pr ovide the best protection.
When driving, keep hands and arms out of the
deployment path of the fro nt airbag by holding each
side of the steering wheel. Do not cross an arm over
the airbag cover.

Safe Driving
Types of Airbags
Your vehicle is equipped wi th three types of airbags:
• Front airbags: Airbags in front of the driver’s and front passenger’s seats.
• Side airbags: Airbags in the driver’s and front passenger’s seat-backs.
• Side curtain airbags: Airbags above the side windows.
Each is discussed in the following pages.
Front Airbags (SRS)
The front SRS airbags inflate in a moderate-to-severe frontal collision to help protect
the head and chest of the driver and/or front passenger.
SRS (Supplemental Restraint System) indica tes that the airbags are designed to
supplement seat belts, not replace them . Seat belts are the occupant's primary
restraint system.
The front airbags are housed in the center of the steering wheel for the driver, and
in the dashboard for the front pass enger. Both airbags are marked SRS AIRBAG.
*1: Models with the smart entry system have an ENGINE START/STOP button instead of an
ignition switch.
■Housing Locations
1 Types of Airbags
The airbags can inflate whenever the ignition switch
is in ON
(w*1.
After an airbag inflates in a crash, you may see a
small amount of smoke. This is from the combustion
process of the infl ator material and is not harmful.
People with respiratory pr oblems may experience
some temporary discomfort. If this occurs, get out of
the vehicle as soon as it is safe to do so.
1 Front Airbags (SRS)
During a frontal crash severe enough to cause one or
both front airbags to deploy, the airbags can inflate
at different rates, dependi ng on the severity of the
crash, whether or not the se at belts are latched, and/
or other factors. Frontal airbags are designed to
supplement the seat belts to help reduce the
likelihood of head and chest injuries in frontal
crashes.

uuAirbags uFront Airbags (SRS)
52
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 protection 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 are 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 caus e 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.

uuAirbags uFront Airbags (SRS)
54
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 Front 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 objec ts 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.•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.
