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 or
the driver’s knee airbag.
Are the motor-powered pretensioners that
start to retract the front seat belts when the
CMBS
TM, brake assist system, or VSA ® system
is in operation. They may also activate when
you steer the vehicle hard, or the vehicle is
impacted. After being retracted, the seat belts
are slackened to thei r original positions.
As convenient features, the e-pretensioners
slightly retract the seat belts when you latch
the seat belt buckle, depress the brake pedal
more aggressively than you normally do, or
make a sharp turn, and fully retract when you
release the seat belt buckle.
■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.
■Seat Belt e-pretensioners1Seat Belt e-pretensioners
If only the e-pretensione rs were activated, no
components need to be replaced.
The e-pretensioners may not work if:
•Supplemental Restraint System Indicator is on.•Vehicle Stability Assist (VSA® ) System Indicator is
on.
•A warning message for e- pretensioners appears on
multi-information display.

uuAirbags uAirbag System Components
Safe Driving
The front, driver’s knee, front 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.
bDriver’s knee airbag. The knee airbag is
stored under the steering column. It is
marked SRS AIRBAG.
cTwo side airbags, one for the driver and
one for a 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, above the side windows.
The front and rear pillars are marked
SIDE CURTAIN AIRBAG.
eAn electronic control unit that, when the
vehicle is on, continually monitors
information about the various impact
sensors, seat and buckle sensors, rollover
sensor, airbag activators, seat belt
tensioners, and other vehicle
information. During a crash event the
unit records such information.
fAutomatic front seat belt tensioners. In
addition, the driver's and front
passenger's seat belt buckles incorporate
sensors that detect whether or not the
belts are fastened.
The front seat belt tensioners also include
the e-pretensioners.
gA driver’s seat position sensor. If the seat
is too far forward, the airbag will inflate
with less force.
hWeight sensors in the front passenger’s
seat. The front passenger’s airbag will be
turned off if the weight on the seat is
approximately 65 lbs (29 kg) or less (the
weight of an infant or small child).
iImpact sensors that can detect a
moderate-to-severe front or side impact.
jAn indicator on the dashboard that alerts
you that the front passenger’s front
airbag has been turned off.
kAn indicator on the instrument panel that
alerts you to a possible problem with your
airbag system or seat belt tensioners.
lSafing Sensor
mA rollover sensor that can detect if your
vehicle is about to roll over and signal the
control unit to deploy both side curtain
airbags.

uuAirbags uFront Airbags (SRS)
Safe DrivingFront airbags are designed to inflate duri ng 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.

Safe Driving
■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 du ring 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: Seat belts, and in vehicl es equipped with a rollover sensor, side curtain
airbags offer the best protection in a ro llover. Because front airbags could provide
little if any protection, they are not designed to deploy during a rollover.
■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 DrivingYour front airbags have advanced features to help reduce the likelihood of airbag
related injuries to smaller occupants.
The driver’s advanced front 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 passenger’s advanced front airbag system
has weight sensors.
Although we recommend against letting
children under the age of 12 sit in passenger
seat, if the sensors detect the weight of a child
(up to about 65 lbs or 29 kg), the system will
automatically turn off the passenger’s front
airbag.
■Advanced Airbags1 Advanced Airbags
If there is a problem with the driver’s seat position
sensor, the SRS indicator wi ll come on and the airbag
will inflate with full (normal) force, regardless of the
driver’s seating position.
For both advanced front 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 place any cover over the passenger side
dashboard. 2Passenger Airbag Off Indicator P. 56
Make sure the floor mat behind the front passenger's
seat is hooked to the floor mat anchor. An improperly
placed mat can interfere with the advanced airbag

Safe Driving■When the passen ger airbag off
indicator comes on
The indicator comes on to alert you that the
passenger’s front airbag has been turned off.
This occurs when the weight sensors detect
about 65 lbs (29 kg) or less, the weight of an
infant or small child, on the seat.
Children under the age of 12 should always ride properly restrained in a back seat.
2Child Safety P. 58
Objects placed on the seat can also cause the indicator to come on.
If the front passenger seat is empty, the pa ssenger’s front airbag will not deploy and
the indicator will not come on.
■Passenger Airbag Off Indicator1 Passenger Airbag Off Indicator
If the indicator comes on with no front passenger and
no objects on the passenger’s seat, or with an adult
riding there, something may be interfering with the
weight sensors, such as:
•An object hanging on the seat or in the seat-back
pocket.
•A child seat or other obj ect pressing against the
rear of the seat-back.
•A rear passenger pushing or pulling on the back of
the front passe nger’s seat.
•The front seat or seat-back is forced back against
an object on the seat or floor behind it.
•An object placed under th e front passenger’s seat.
If none of these conditions exist, have your vehicle
checked by a dealer as soon as possible.
The passenger airbag off indicator may come on and
goes off repeatedly if the to tal weight on the seat is
near the airbag cutoff threshold.

uuChild Safety uSafety of Infants and Small Children
Safe DrivingIf a child is at least one year old and has exceeded the weight and height limitations
of a rear-facing child seat, the child should be properly restrained in a firmly secured
forward-facing child seat until they exceed the weight and height limitations for the
forward-facing child seat.
■Forward-facing child seat placement
We strongly recommend placing a forward-
facing child seat in a rear seating position.
Placing a forward-facing child seat in th e front seat can be hazardous, even with
advanced front airbags that automatically turn the passeng er’s front airbag off. A
rear seat is the safest place for a child.
■Protecting Smaller Children1 Protecting Smaller Children
Educate yourself about th e laws and regulations
regarding child seat use wh ere you are driving, and
follow the child seat manufacturer’s instructions.
Many experts recommend us e of a rear-facing seat
for a child up to two years old if the child’s height and
weight are appropriate for a rear-facing seat.
3WARNING
Placing a forward-facing child seat in the
front seat can result in serious injury or
death if the front airbag inflates.
If you must place a forward-facing child
seat in front, move the vehicle seat as far
back as possible, and properly restrain the
child.
