Safe Driving
Safety Checklist
For the safety of you and your passengers, make a habit of checking these items
each time before you drive.
• After everyone has entered the vehicle, be sure all doors and the hatch are closed
and locked. Locking the doors and the hatch helps prevent an occupant from
being ejected and an outsider from unexpectedly opening a door or the hatch.
2 Locking/Unlocking the Doors from the Inside P. 156
•Adjust your seat to a position suitable for driving. Be sure the front seats are
adjusted as far to the rear as possible while allowing the driver to control the
vehicle. Sitting too close to a front airbag can result in serious or fatal injury in a
crash.
2 Adjusting the Seats P. 193
•Adjust head restraints to the proper position. Head restraints are most effective
when the center of the head restraint alig ns with the center of your head. Taller
persons should adjust their head restraint to the highest position.
2Adjusting the Front Head Restraints Positions P. 196
•Always wear your seat belt, and make sure you wear it properly. Confirm that any
passengers are properly belted as well.
2 Fastening a Seat Belt P. 44
•Protect children by using seat belts or child seats according to a child’s age, height
and weight.
2 Child Safety P. 64
1Safety Checklist
If the door and hatch open message appears on the
driver information interfac e, a door and/or the hatch
is not completely closed. Close all doors and the
hatch tightly until th e message disappears.

Safe DrivingThe 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 the ignition switch is turned to ON
(w*1 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.
*1: Models with the smart entry system have an ENGINE START/STOP button instead of an
ignition switch.
■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 ignition switch is turned to ON
( w*1.
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.

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 a 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, abov e the side windows.
The front and rear pillars are marked
SIDE CURTAIN AIRBAG .
dAn electronic control unit that, when the
ignition switch is in ON
(w*1, 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.
eAutomatic 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.
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.
kA 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 uTypes of Airbags
Continued
Safe Driving
Types of Airbags
Your vehicle is equipped wi th three types of airbags:
• Front airbags: Airbags in front of the driver’s and front passenger’s seats.
• Side airbags: Airbags in the driver’s and front passenger’s seat-backs.
• Side curtain airbags: Airbags above the side windows.
Each is discussed in the following pages.
Front Airbags (SRS)
The front SRS airbags inflate in a moderate-to-severe frontal collision to help protect
the head and chest of the driver and/or front passenger.
SRS (Supplemental Restraint System) indica tes that the airbags are designed to
supplement seat belts, not replace them . Seat belts are the occupant's primary
restraint system.
The front airbags are housed in the center of the steering wheel for the driver, and
in the dashboard for the front pass enger. Both airbags are marked SRS AIRBAG.
*1: Models with the smart entry system have an ENGINE START/STOP button instead of an
ignition switch.
■Housing Locations
1 Types of Airbags
The airbags can inflate whenever the ignition switch
is in ON
(w*1.
After an airbag inflates in a crash, you may see a
small amount of smoke. This is from the combustion
process of the infl ator material and is not harmful.
People with respiratory pr oblems may experience
some temporary discomfort. If this occurs, get out of
the vehicle as soon as it is safe to do so.
1 Front Airbags (SRS)
During a frontal crash severe enough to cause one or
both front airbags to deploy, the airbags can inflate
at different rates, dependi ng on the severity of the
crash, whether or not the se at belts are latched, and/
or other factors. Frontal airbags are designed to
supplement the seat belts to help reduce the
likelihood of head and chest injuries in frontal
crashes.
