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 trip. Slouching and leaning reduc e 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 be lts. Devices intended to improve comfort
or reposition the shoulder part of a seat be lt can reduce the protective capability
and increase the chance of serious injury in a crash.
The seat belt system includes an indicator on
the instrument panel to remind the driver or a
front passenger or both to fasten their seat
belts.
If you set the power mode to ON and a seat
belt is not fastened, a beeper will sound and
the indicator will blink. After a few seconds,
the beeper will stop and the indicator will
come on and remain illuminated until the seat
belt is fastened.
The beeper will periodically sound and the
indicator will blink while the vehicle is moving
until the seat belt is fastened.
■Seat Belt Reminder
1 About Your Seat Belts
Seat belts cannot complete ly protect you in every
crash. But in most cases, seat belts can reduce your
risk of serious injury.
Most states and all Canadian provinces and territories
require you to w ear seat belts.
The pickup bed is not equipp ed with seats or seat
belts. Do not let anyone ride in the pickup bed as they
can easily be thrown out and be killed or seriously
injured.
1 Seat Belt Reminder
The indicator will also co me on if a front passenger
does not fasten their seat be lt within six seconds after
the power mode is set to ON.
When no one is sitting in th e front passenger’s seat,
the indicator will not come on and the beeper will not
sound.
The indicator also may no t come on and the beeper
may not sound when the occupant is not heavy
enough to trigger the weight sensor. Such occupants
(e.g., infants and smaller children) should be moved
to the rear seat as a deploying front airbag likely will
injure or kill them. 2 Protecting Child Passengers P. 59

uuAirbags uAirbag System Components
Continued
Safe Driving
The front, 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.
bTwo side airbags, one for the driver and
one for the front passenger. The airbags
are stored in the outer edges of the seat-
backs. Both are marked SIDE AIRBAG.
cTwo side curtain ai rbags, 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, when the
power mode is in ON, continually
monitors information about the various
impact sensors, seat and buckle sensors,
rollover sensor, airbag activators, seat
belt tensioners, passenger seat weight
sensors, driver’s seat position sensor,
passenger airbag off indicator and other
vehicle information. During a crash event
the unit can record such information.
eSeat belt tensioners for the front seats. In
addition, the driver’s and front
passenger’s seat belt buckles incorporate
sensors that detect whether or not the
belts are fastened.
fDriver’s seat position sensor. This sensor
detects the driver’s s eat slide position to
help determine the optimal deployment
of the driver’s airbag.
gWeight sensors in the front passenger’s
seat. The sensors are used for occupant
classification to activate or deactivate the
front passenger’s airbag.
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.
jAn indicator on the instrument panel that
alerts you to a possib le problem with your
airbag system or seat belt tensioners.
kSafing Sensor
lA rollover sensor that can detect if your
vehicle is about to ro ll over and signal the
control unit to deploy both side curtain
airbags.

uuAirbags uFront Airbags (SRS)
48
Safe DrivingFront airbags are designed to inflate du ring 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 side curtain airbags deploy in a frontal collision
One or both side curtain ai rbags may also inflate in a moderate-to-severe angled
frontal collision.
Airbag System Indicators
If a problem occurs in the airbag system , the SRS indicator will come on and a
message appears on the mu lti-information display.
■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 s oon as possible. If you
don’t, your airbags and seat belt tensioners
may not work properly when they are needed.

Ignoring the SRS indicator can result in
serious injury or death if the airbag systems
or tensioners do not work properly.
Have your vehicle checked by a dealer as
soon as possible if th e SRS indicator alerts
you to a possible problem.
