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.

Safe DrivingThe airbags have advanced features to help reduce the likelihood of airbag related
injuries to smaller occupants.
The driver’s advanced airbag system includes a
seat position sensor.
Based on information from this sensor and the
severity of the impact, the advanced airbag
system determines the optimal deployment of
the driver’s airbag.
The front passenger’s advanced airbag system
has weight sensors. The sensors are used for
occupant classification to activate or
deactivate the front passenger’s airbag.
For adult size occupants, the system will
automatically activate the front passenger’s
airbag. If a small adul t sits in the front
passenger seat and the system does not
recognize him/her as an adult, see
2 Passenger Front Airbag Off Indicator P. 61
■Advanced Airbags1Advanced Airbags
If there is a problem with the driver’s seat position
sensor or the passenger’s s eat weight sensors, the
SRS indicator will come on, and in the event of a
crash, the airbag will deploy (regardless of the driver’s
seating position or passenger’s occupant
classification) with a force corresponding to the
severity of the impact. 2 Supplemental Restraint System (SRS)
Indicator P. 60
For the advanced front airbags to work properly,
confirm that:
•The occupant is sitting in an upright position,
wearing the seat belt prope rly and the seat back is
not excessively reclined.
•The occupant is not leaning against the door or
center console.
•The occupant’s feet are plac ed on the floor in front
of them.
•There are no objects ha nging from the front
passenger’s seat.
•Only small, lightweight objec ts are in the seat back
pocket.
•The steering wheel and passenger’s side dashboard
are not obstructed by any object.
•No liquid has been spille d on or under the seat.•There is no child seat or other object pressing
against the rear of the seat or seat back.
•There is no rear passenger pushing or pulling on
the back of the front passenger’s seat.
