The airbag control unit monitors the readiness of the electronic
parts of the system whenever the ignition switch is in the “ON”
or “START” position. These include all of the items listed
above and all related wiring.
The airbags will operate only when the ignition switch is in the
“ON” or “START” position. When the impact sensors detect a sufficient front or side impact
to deploy the airbag(s), the appropriate airbag(s) will be
deployed.
When airbags deploy, some smoke is released accompanied by
a loud noise. The smoke is not harmful, but do not intentionally
inhale the smoke as it may cause temporary irritation to people
with respiratory problems.
After deployment, the airbags will quickly deflate, so quickly
that some people may not even realize the airbags inflated.
Airbag inflation does not prevent the driver from seeing or
being able to steer the vehicle, and does not prevent people
from leaving the vehicle.10- Side airbag modules

CAUTION
!

Airbags inflate very quickly and with great force. In
certain situations, contact with an inflating airbag
may cause small cuts, abrasions, and bruises.

Event Data Recording
N00418600171
Your vehicle is equipped with an “EDR” - Event Data
Recorder which is capable of collecting and storing data in the
event of an airbag deployment.
The EDR may record the following information:

Condition of specific vehicle systems;


Diagnostic code(s)
Driver’s seat position sensor
N00417900180
The driver’s seat position sensor is attached to the seat rail and
provides the airbag control unit with information on the seat’s
fore-aft position. The airbag control unit controls deployment
of the driver’s front airbag in accordance with the information
it receives from this sensor.
If there is a problem involving the driver’s seat position sensor,
the SRS warning in the instrument panel will come on. Refer to
“SRS warning light/display” on page 2-46.

Passenger’s seat weight sensors
N00418000292
The passenger’s seat weight sensors are attached to the seat
rails and provide the airbag control unit with information
regarding the weight on the front passenger seat. The airbag
control unit controls deployment of the passenger’s front air-
bag in accordance with the information it receives from this
sensor.
The passenger’s front airbag will not deploy in an impact when
the weight on the seat is sensed to be less than approximately
66 pounds (30 kg). In this case, the passenger’s airbag off indi-
cator will come on.
Refer to “Passenger’s airbag off indicator” on page 2-45.
If there is a problem involving the passenger’s seat weight sen-
sors, the SRS warning in the instrument panel will come on.

Passenger’s airbag off indicator
N00418100251
The passenger’s airbag off indicator is located in the instru-
ment panel.
The indicator normally comes on when the ignition switch is
turned to the “ON” position and goes out a few seconds later.

The driver’s airbag is located under the padded cover in the
middle of the steering wheel. The front passenger’s airbag is
contained in the instrument panel above the glove compart-
ment. The driver’s airbag and the front passenger’s airbag are
designed to deploy at the same time. However, the front pas-
senger’s airbag does not deploy when the front passenger seat
is not occupied or when the weight sensor in the front passen-
ger seat senses a weight on the seat of less than approximately
66 pounds (30 kg).

Deployment of front airbags
N00408000550
The front airbags and driver’s knee airbag ARE DESIGNED TO DEPLOY when… The front airbags and driver’s knee airbag are designed to
deploy when the vehicle suffers a moderate to severe frontal
impact. A typical condition is shown in the illustration to the
left.
The front airbags and driver’s knee airbag are designed to
deploy only in certain moderate to severe frontal collisions
within the shaded area between the arrows in the illustration to
the right.
The front airbags and driver’s knee airbag will deploy if the
impact to the vehicle’s main structure is above a specific
threshold level. The threshold level is approximately 15 mph
(25 km/h) for a frontal collision straight into a solid flat wallthat does not bend or deform. If the impact to the vehicle’s
main structure is below this threshold level, the front airbags
and driver’s knee airbag may not deploy. This threshold level
may also be higher if the vehicle hits something that absorbs
the impact, either by bending or moving (for example, another
stationary vehicle, a pole or a guard rail).
The beginning stage of airbag inflation is the most forceful,
and can cause serious injuries or death if you are too close to
the deploying airbag. Accordingly, it is important that you
always wear the available seat belt.

The front airbags and driver’s knee airbag MAY NOT
DEPLOY when … In certain types of front collisions, the front airbags and
driver’s knee airbag may not deploy, even if the deformation of
the body seems to be large, because the vehicle’s body struc-
ture is designed to absorb the impact and deform in order to
help protect the occupants. Some typical situations where the
front airbags and driver’s knee airbag may not deploy are
shown in the illustrations.
Because the front airbags and driver’s knee airbag do not pro-
tect the occupant in all types of frontal collisions, be sure to
always wear your seat belts properly.
