Your Vehicle's Safety Features
The following checklist will help you take an active role in protecting yourself and
your passengers.
1 Your Vehicle's Safety Features
Your vehicle is equipped wi th many features that
work together to help protect you and your
passengers during a crash.
Some features do not require any action on your part.
These include a strong steel framework that forms a
safety cage around the passenger compartment,
front and rear crush zones, a collapsi ble steering
column, and tensioners that tighten the front seat
belts in a sufficient crash.
However, you and your passe ngers cannot take full
advantage of these features unless you remain seated
in the correct position and always wear your seat
belts. In fact, some safety features can contribute to
injuries if they are not used properly.

uuSeat Belts uAbout Your Seat Belts
Safe Driving
■Proper use of seat belts
Follow these guidelines for proper use:
• All occupants should sit upright, well back in the seat, and remain in that position
for the duration of the tr ip. Slouching and leaning re duces the effectiveness of
the belt and can increase the chance of serious injury in a crash.
• Never place the shoulder part of a lap/shoulder seat belt under your arm or
behind your back. This could cause very serious injuries in a crash.
• Two people should never use the same seat belt. If they do, they could be very
seriously injured in a crash.
• Do not put any accessories on the seat belt s. Devices intended to improve comfort
or reposition the shoulder part of a seat belt can reduce the protective capability
and increase the chance of serious injury in a crash.
Your vehicle monitors front seat belt use. If
the power mode is set to ON before the
driver's seat belt is fastened, a beeper will
sound and the indicator will blink. If the driver
does not fasten the belt before the beeper
stops, the indicato r will remain on.
The beeper will also periodically sound and
the indicator will blink while driving until the
driver's and front passenger’s seat belts are
fastened.
■Seat Belt Reminder
1 About Your Seat Belts
If a rear seat passenger moves around and extends
the seat belt, the lockable retractor may activate. If
this happens, release the retractor by unfastening the
seat belt and allow the belt to retract completely.
Then refasten the belt.
1 Seat Belt Reminder
The indicator will also co me on if a front passenger
does not fasten their seat be lt within 6 seconds after
the power mode is set to ON.
When no one is sitting in th e front passenger's seat,
or a child or small adult is riding there, the indicator
will not come on.
This is because the weight sensors in the seat cannot
detect their presence.

uuAirbags uAirbag System Components
Safe Driving
The front, front side, and side curtain
airbags are deployed according to the
direction and severity of impact. 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.
bTwo 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 .
cTwo 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.
dAn electronic control unit that continually
monitors and can re cord information
about the sensors, the airbag activators,
the seat belt tensioners, and driver and
front passenger seat belt use when the
power mode is in ON.
eAutomatic front seat belt tensioners. The
driver's and front passenger's seat belts
incorporate sensors that detect whether
or not they are fastened.
fA driver's seat position sensor. If the seat
is too far forward, the airbag will inflate
with less force.
gWeight sensors in the front passenger's
seat. The front passenger's airbag will be
turned off if the weight on the seat is 65
lbs (29 kg) or less (the weight of an infant
or small child).
hImpact sensors that can detect a
moderate to severe front or side impact.
iAn indicator on the dashboard that alerts
you that the front passenger's front
airbag has been turned off.
jSensors that can detect if a child or small
statured adult is in the deployment path
of the front passenger's side airbag.
kAn indicator on the instrument panel that
alerts you to a possible problem with your
airbag system or seat belt tensioners.
lAn indicator on the instrument panel that
alerts you that the fr ont passenger's side
airbag has been turned off.

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.

uuAirbags uFront Airbags (SRS)
Safe Driving
■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 passenger to move towards 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 durin g 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 airbags
and side curtain airbags offer the best prot ection 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 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.
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 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.
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. 299

uuAirbags uSide Airbags
Safe Driving
Side Airbags
The side airbags help protect the upper to rso 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
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.
If the impact is on the passenger side, the airbag
deploys even if there is no passenger’s in the
passenger seat.
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.

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 to not deploy during an impact that results in
apparently severe damage. This can occu r when the point of impact was towards
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 protec tion even if it had deployed.

Safe DrivingTo reduce the likelihood that a front passeng er may be injured by an inflating side
airbag, the passenger side airbag is automatically turned off when:
• The height sensors detect a child or sho rt-statured adult is seated in the front
passenger seat.
• The position sensor detects that the front passenger is leaning into the
deployment path of the side airbag.
When the side airbag cutoff system is acti vated, the side airbag off indicator comes
on.
2 Side Airbag Off Indicator P. 46
If the side airbag off indicator comes on, have the passenger sit upright. A few
seconds after the passenger is sitting properly, the side airbag will automatically be
turned on, and the indicator will go off.
If the front passenger is a child, stop when it is safe to do so, and have the child sit
properly restrained in a rear seat.

uuAirbags uAirbag System Indicators
Safe Driving■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 ri de properly restrained in a back seat.
2Child Safety P. 48
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 wi th 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.
