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, abov e the side windows. 
The front and rear pillars are marked 
SIDE CURTAIN AIRBAG .
dAn electronic control unit that, when the 
vehicle is 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.
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.
fA driver’s seat position sensor. This 
sensor detects the driver’s seat 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.

Safe DrivingAirbags can pose serious hazards. To do  their job, airbags must inflate with 
tremendous force. So, while airbags help save lives, they can cause burns, bruises, 
and other minor injuries, sometimes even  fatal ones if occupants are not wearing 
their seat belts properly and sitting correctly.
What you should do:  Always wear your seat belt  properly, and sit upright and as 
far back from the steering wheel as possi ble while allowing full control of the 
vehicle. A front passenger should move their seat as far back from the dashboard as 
possible.
Remember, however, that no safety system  can prevent all injuries or deaths that 
can occur in a severe crash,  even when seat belts are properly worn and the airbags 
deploy.
Do not place hard or sharp objects  between yourself and a front airbag.  
Carrying hard or sharp objects on your lap,  or driving with a pipe or other sharp 
object in your mouth, can result in in juries if your front airbag inflates.
Do not attach or place object s on the front airbag covers. Objects on the 
covers marked SRS AIRBAG  could interfere with the proper operation of the airbags 
or be propelled inside the vehicle an d hurt someone if the airbags inflate.
■Important Facts About Your Airbags1Important Facts About Your Airbags
Do not attempt to deactivate your airbags. Together, 
airbags and seat belts pr ovide the best protection.
When driving, keep hands and arms out of the 
deployment path of the fro nt airbag by holding each 
side of the steering wheel.  Do not cross an arm over 
the airbag cover.

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.
