uuAirbags uFront Airbags (SRS)
Safe DrivingFront airbags are designed to inflate durin g 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 deployed until th ey 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 to save lives, not to prevent minor scrapes, or even broken bones that might
occur during a less than modera te-to-severe frontal crash.
Side impacts: Front airbags can provide protection when a sudden deceleration
causes a driver or front passenger to move towards the front of the vehicle. Side
airbags and side curtain airbag s have been specifically designed to help to reduce
the severity of injuries that can occur dur ing a moderate-to-severe side impact which
can cause the driver or passenger to move towards 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 se at belt and a side curtain airbag. Front
airbags, however, are not designed to deploy 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.

51
uuAirbags uFront Airbags (SRS)
Safe DrivingThe airbags have advanced features to he lp 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 ad vanced airbag system
has weight sensors.
We advise against allowi ng a child age 12 or
under to ride in the front passenger’s seat.
However, if you do allow a child age 12 or
under to ride in the front passenger’s
seat, note that the system will automatically
turn off the front passenger’s airbag if the
sensors detect that the child is approximately
65 lbs (29 kg) or less.
■Advanced Airbags1 Advanced Airbags
If there is a problem with the driver’s seat position
sensor, the SRS indicator wi ll come on, and in the
event of a crash, the airbag will deploy (regardless of
the driver’s seating position) with a force
corresponding to the se verity of the impact.
For the advanced airbags to work properly:
•Do not spill any liquid on or under the seats.
•Do not put any object under the passenger’s seat.
•Make sure any objects are positioned properly on
the floor. Improperly pos itioned objects can
interfere with the advanced airbag sensors.
•All occupants should sit upri ght and wear their seat
belts properly.
•Do not cover the passenger ’s side dashboard with
a cloth, towel, cover, etc. 2 Passenger Front Airbag Off Indicator P. 59

Knee Airbags
The knee SRS airbags inflates in a moderate -to-severe frontal collision to help keep
the driver and/or front passenger in the proper position and to help maximize the
benefit provided by the vehicle’s other safety features.
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 driver’s knee airbag is housed under the
steering column.
The front passenger’s knee airbag is housed
under the glove box.
Both are marked SRS AIRBAG.
■Housing Locations
1Knee Airbags
Do not attach accessories on or near the knee
airbags. They can interfer e with the proper operation
of the airbags, or hurt someone if an airbag inflates.
The driver and fr ont passenger should not store any
items under the seat or be hind their feet. The items
can interfere with proper airbag deployment in the
event of a moderate to se ver frontal collision and may
result in inadequate protection.

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.

■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.

Side Curtain Airbags
The side curtain airbags help protect the heads of the driver and passengers in the
outer seating positions during a moderate-to -severe side impact. The side curtain
airbags equipped in this vehicle are also de signed to help reduce the likelihood of
partial and complete ejection of vehicle occupants through side windows in crashes,
particularly rollover crashes.
The side curtain airbags are located in the
ceiling above the side windows on both sides
of the vehicle.
The side curtain airbag is designed to deploy
in a rollover or a moderate-to-severe side
impact.
■Housing Locations
1 Side Curtain Airbags
To get the best protecti on from the side curtain
airbags, occupants should wear their seat belts
properly and sit upr ight and well back in their seats.
Do not attach any objects to the side windows or roof
pillars as they can interfere with the proper operation
of the side curtain airbags.
If the impact is on the passenger’s side, the
passenger’s side curtain airbag deploys even if there
are no occupants on that side of the vehicle.
If the SRS control unit sens es that your vehicle is
about to rollover, it imme diately deploys both side
curtain airbags and activates both front seat belt
tensioners.

Airbag System Indicators
If a problem occurs in the airbag syst em, the SRS indicator will come on and a
message appears on the Driver information interface.
■When the power mode is set to ON
The indicator comes on for a few seconds,
then goes off. This tells you the system is
working properly.
If the indicator comes on at any other time, or does not come on at all, have the
system checked by a dealer as soon as possi ble. If you don’t, your airbags and seat
belt tensioners may not work properly when they are needed.
