Types of Airbags
Your vehicle is equipped with 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) indicates 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 passenger. Both airbags are marked SRS AIRBAG.
■Housing Locations
1Types of Airbags
The airbags can inflate whenever the ignition switch
is in ON

1Front Airbags (SRS)
Dual-Stage, Multiple-Threshold Front Airbags (SRS)
Your vehicle is equipped with dual-stage, multiple-
threshold 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, depending on the severity of the
crash, whether or not the seat 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.

uuAirbagsuFront Airbags (SRS)
Safe DrivingYour front airbags have advanced features to reduce the likelihood of airbag related injuries to smaller occupants.The driver's advanced front airbag system
includes a seat position sensor.
If the seat is too far forward, the airbag
inflates with less force, regardless of the
severity of the impact.
The passenger's advanced front airbag system
has weight sensors.
Although Honda recommends against
carrying an infant or small child in front, if the
sensors detect the weight of a child (up to
about 65 lbs or 29 kg), the system will
automatically turn off the passenger's front
airbag.
■Advanced Airbags1Advanced Airbags
If there is a problem with the driver's seat position
sensor, the SRS indicator will come on and the airbag
will inflate with full (normal) force, regardless of the
driver's seating position.
For both advanced front airbags to work properly: • Do not spill any liquid on or under the seats.
• Do not put any object under the passenger’s seat.
• Make sure any objects are positioned properly on
the floor. Improperly positioned objects can
interfere with the advanced airbag sensors.
• All occupants should sit upright and wear their seat
belts properly.

Safe DrivingTo reduce the likelihood that a front passenger may be injured by an inflating side
airbag, the passenger side airbag is automatically turned off when: • The height sensors detect a child or short-statured adult is seated in the front
passenger seat.
• The position sensor detects that the front passenger is leaning into the
deployment path of the side airbag.
When the side airbag cutoff system is activated, the side airbag off indicator comes
on. 2 Side Airbag Off Indicator P. 48
If the side airbag off indicator comes on, have the passenger sit upright. A few
seconds after the passenger is sitting properly, the side airbag will automatically be
turned on, and the indicator will go off.
If the front passenger is a child, stop when it is safe to do so, and have the child sit
properly restrained in a rear seat.
