uuSeat Belts uAbout Your Seat Belts
Safe Driving
The 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 retracted, the seat belts are
slackened to their 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.

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.

uuAirbags uFront Airbags (SRS)
Safe Driving
Front 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 deployed until they see them lying in front of them.■

How the Front Airbags Work
1 How the Front Airbags Work
Although the driver’s and front passenger’s airbags
normally inflate within a split 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 protection, 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 prevent minor scrapes, 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 passen ger 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 mov e 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: Seat belts, and in vehicles equipped with a rollover sensor, side airbags,
and side curtain airbags offer the best protection in a rollover. 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 su dden 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 the vehicle chassis. Since the impact is
underneath the vehicle, damage may not be readily apparent.■When front airbags may not deploy, eve n 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 Driving
Your 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.
If the seat is too far forward, the airbag
inflates with less force, regardless of the
severity of the impact.
The passenger’s advanced front airbag system
has weight sensors.
Although we recommend against carrying an
infant or small child in front, 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 Airbags
1Advanced Airbags
If there is a problem with the driver’s seat position
sensor, the SRS indicator will come on and the airbag
will inflate with full (nor mal) 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 positioned objects can
interfere with the advanced airbag sensors.•All occupants should sit upright and wear their seat
belts properly.•Do not place any cover over the passenger side
dashboard.
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
sensors. 2 Floor Mats P. 437

■When side curtain airbags deploy in a frontal collision
One or both side curtain airbags may inflate in a moderate to severe angled frontal
collision.
In this case, the side curtain airbags will deploy slightly after the front airbags.Airbag System IndicatorsIf a problem occurs in the airbag system, the SRS indicator will come on and a
message appears on the MID.
■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 possible. If you
don’t, your airbags and seat belt tensioners
may not work properly when they are needed.

■When the passenger 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 front passenger’s weight
sensors detect 65 lbs (29 kg) or less, the
weight of an infant or small child, on the seat.
Infants and small children should always ride properly restrained in a back seat.
2 Child Safety P. 54Objects placed on the seat can also cause the indicator to come on.
If the front passenger seat is empty, the passenger’s front airbag will not deploy and
the indicator will not come on.■
Passenger Airbag Off Indicator
1 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 object pressing against the
rear of the seat-back.•A rear passenger pushing or pulling on the back of
the front passenger’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 the front passenger’s seat.
If none of these conditions exist, have your vehicle
checked by a dealer as soon as possible.
The passenger airba g off indicator may come on and
goes off repeatedly if the total weight on the seat is
near the airbag cutoff threshold.

Safe Driving
If a child is at least one year old and within the weight range indicated by the child
seat manufacturer, the child should be properly restrained in a firmly secured
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 the front seat can be hazardous, even with
advanced front airbags that automatically turn the passenger’s front airbag off. A
rear seat is the safest place for a child.

Protecting Smaller Children
1 Protecting Smaller Children
Educate yourself about the laws and regulations
regarding child seat use where you are driving, and
follow the child seat manufacturer’s instructions.
Many experts recommend use of a rear-facing seat
for a child up to two years old if the child’s height and
weight are appropriate for a re ar-facing seat.

WARNING
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.
