■When front airbags should not deploy
Minor frontal crashes: Front airbags were designed to supplement seat belts and
help save lives, not to prevent minor scrape s, or even broken 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 airbag s 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 significant 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.

uuAirbags uFront Airbags (SRS)
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.
■Advanced Airbags1 Advanced 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. 59
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.

Safe Driving
The front passenger’s ad vanced 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
2Passenger Airbag Off Indicator P. 60
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 the front
passenger’s seat if the airbag does not
automatically deactivate.

Knee Airbags
The knee SRS airbags inflate in a moderate -to-severe frontal collision to help keep
the driver and/or front passenger in the pr oper 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 knee airbag for the driver and the one for
the front passenger are housed under the
steering column and the glove box
respectively.
Both are marked SRS AIRBAG.
■Housing Locations
1Knee Airbags
Do not attach accessories on or near the knee airbags
as they can interfere with the proper operation of the
airbags, or even hurt someone if the airbags inflate.
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 vere frontal collision and
may result in inadequate protection.

uuAirbags uSide Airbags
Safe Driving
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.
Side airbag deployment is controlled by a pressure
sensor inside each front door . Damage or changes to
the inside or outside of the doors may negatively
affect side airbag deployme nt. Contact an authorized
dealer before ch anging or repairing a front door.

uuAirbags uSide Airbags
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.

uuAirbags uSide Curtain Airbags
Safe Driving
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 th is vehicle are also designed 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
1Side 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 the seat belt tensioners
for the front seats and the second row outer seats.
