Safe Driving■Front seats
The seat belt system in cludes 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 Reminder1 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 not come on and the
beeper may not sound when the occupant is not
heavy enough to trigger th e 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.

The driver information interface uses colors to aid the
driver in checking the st atus of the passengers.
For the front seating positions:
•Green indicates the seat belt is fastened.
•An unfastened gray graphic indicates the seat belt
is not fastened and an occupant has not been
detected.
•An unfastened red graphic i ndicates the seat belt is
unfastened and an occupa nt has been detected.

■Rear seats
Your vehicle monitors rear seat belt use.
A driver information interface notifies you if
any of the rear seat belts are not used.
The display appears when:
• Any of the rear passengers' seat belts are
unfastened when the power mode is
turned to ON.
• A rear door is opened and then closed.
• Any of the rear passengers fastens or
unfastens their seat belt.
The seat belt reminder indicator blinks and
beeper sounds if any rear passenger's seat belt
is unfastened while driving.

The system will not detect a passenger in the rear
seats who has not fastened the seat belt.
The driver should check the status of the rear
passengers' seat belts at th e start of each trip and
each time a passenger is seated in the rear seats,
using the driver information interface as an aid.
An alert will sound if a pa ssenger in the rear seats
unfastens the seat belt whil e the vehicle is in motion

was unfastened recently.
The system does not monito r harnesses that are part
of a child seat, the anchors of the LATCH system, or

While the system can inform you that a seat belt
buckle is fastened, it ca nnot determine whether the

uuAirbags uAirbag System Components
Safe Driving
The front, driver's knee, front passenger's
knee, side, and side curtain airbags are
deployed according to the direction and
severity of impact. Both side curtain airbags
are deployed in a ro llover. 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 knee airbags. Th e driver's knee
airbag is stored under the steering
column; the front passenger's knee
airbag is stored under the glove box.
Both are marked SRS AIRBAG.
cFour side airbags, one for the driver, one
for the front passenger and two for the
rear outboard. The front airbags are
stored in the outer edges of the seat-
backs and the rear airbags are stored next
to the outer rear seating positions. All 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
power mode is in 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 can record such information.
fAutomatic seat belt tensioners for the
front seats and outer rear seats. In
addition, the driver's and front
passenger's seat belt buckles incorporate
sensors that detect whether or not the
belts are fastened.
gDriver's seat position sensor. This sensor
detects the driver's seat slide position to
help determine the optimal deployment
of the driver's airbag.
hWeight sensors in the front passenger's
seat. The sensors are used for occupant
classification to activa te or deactivate the
front passenger's airbag.
iImpact sensors that can detect a
moderate-to-severe front or side impact.
jAn indicator on the center console 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 possib le problem with your
airbag system or seat belt tensioners.
lA 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.
