When is the SRS frontal airbag unlikely to de-
ploy? There are many types of collisions which might not
necessarily require SRS frontal airbag deployment. If
the vehicle strikes an object, such as a telephone pole
or sign pole, or if it slides under a truck’s load bed, or
if it sustains an oblique offset frontal impact, the SRS
frontal airbag may not deploy depending on the level
of accident forces involved.

"When will the SRS frontal airbag not deploy?
The SRS frontal airbag is basically not designed to de-
ploy if the vehicle is struck from side or from behind, or
if it rolls onto its side or roof, or if it is involved in a low-
speed frontal collision. 1) First impact
2) Second impact
In an accident where the vehicle is impacted more
than once, the SRS frontal airbag deploys only once.
Example: In the case of a double collision, first with an-
other vehicle, then against a concrete wall in immedi-
ate succession, once the SRS frontal airbag is activat-
ed on the first impact, it will not be activated on the second.

SRS side airbag (if equipped)
The SRS side airbag is stored in the door side of each
front seatback, which bears an “SRS AIRBAG” label.
In a moderate to severe side impact collision, the SRS
side airbag on the impacted side of the vehicle de-
ploys between the occupant and the door panel and
supplements the seatbelt by reducing the impact on
the occupant’s chest and head.
The SRS side airbag is designed as only a sup-
plement to the primary protection provided by
the seatbelt. It does not do away with the need
to fasten seatbelts. It is also important to wear
your seatbelt to help avoid injuries that can re-
sult when an occupant is not seated in a proper
upright position.
Do not sit or lean unnecessarily close to either
front door. The SRS side airbag is stored in
both front seat seatbacks next to the door, and
it provides protection by deploying rapidly
(faster than the blink of an eye) in the event of a
side impact collision. However, the force of
SRS side airbag deployment may cause injuries
if your head or other body parts are too close to
the SRS side airbag.

Do not rest your arm on either front door or its
internal trim. It could be injured in the event of
SRS side airbag deployment.

Seat, seatbelt and SRS airbags
Never allow a child to kneel on the front pas-
senger’s seat facing the side window or to wrap
his/her arms around the front seatback. In the
event of an accident, the force of the SRS side
airbag deployment could injure the child seri-
ously because his/her head or arms or other
body parts are too close to the SRS side airbag.
Since your vehicle is also equipped with a pas-
senger’s SRS frontal airbag, children aged 12
and under should be placed in the rear seat
anyway and should be properly restrained at all
times.
Do not attach accessories to the door trim or
near either SRS side airbags and do not place
objects near the SRS side airbags. In the event
of the SRS side airbag deployment, they could
be propelled dangerously toward the vehicle’s
occupants and cause injuries.

Do not put any kind of cover or clothes or other
objects over either front seatback and do not
attach labels or stickers to the front seat sur-
face on or near the SRS side airbag. They could
prevent proper deployment of the SRS side air-
bag, reducing protection available to the front
seat’s occupant. !
Operation
A) SRS side airbag deploys as soon as a collision oc- curs.
B) SRS side airbag protects the front passenger’s head and chest.

C) After deployment, SRS side airbag starts to deflate im-
mediately.
The SRS side airbag can function only when the igni-
tion switch is in the “ON” position.
The driver’s and front passenger’s SRS side airbags
deploy independently of each other since each has its
own impact sensor. Also, the SRS side airbag deploys
independently of the frontal airbags in the steering
wheel and instrument panel.
An impact sensor is incorporated into each of the ve-
hicle’s center pillars. If either sensor detects a certain
predetermined amount of force during a side impact
collision, the control module sends a signal to the side
airbag module on the impacted side of the vehicle, in-
structing it to inflate the SRS side airbag. Then the
side airbag module produces gas, which instantly in-
flates the SRS side airbag. After the deployment, the
SRS side airbag immediately starts to deflate. The
time required from detecting impact to the deflation of
the SRS side airbag after deployment is shorter than
the blink of an eye.
The SRS side airbag deploys even when no one occu-
pies the seat on the side on which an impact is ap-
plied. When the SRS side airbag deploys, a sudden, fairly
loud inflation noise will be heard and some smoke will
be released. These occurrences are normal result of
the deployment. This smoke does not indicate a fire in
the vehicle.
Do not touch the SRS side airbag system com-
ponents around the front seatback with bare
hands right after deployment. Doing so can
cause burns because the components can be
very hot as a result of deployment.
The SRS side airbag is designed to deploy in the event
of an accident involving a moderate to severe side im-
pact collision. It is basically not designed to deploy in
lesser side impact. Also, it is basically not designed to
deploy in frontal or rear impacts because SRS side air-
bag deployment would not help the occupant in those
situations.
Each SRS side airbag is designed to function on a one-time-only basis.
SRS side airbag deployment depends on the level of
force experienced in the passenger compartment dur-
ing a side impact collision. That level differs from one

type of collision to another, and it may have no bearing
on the visible damage done to the vehicle itself. "When will the SRS side airbag most likely de-
ploy?
A severe side impact near the front seat activates the
SRS side airbag.
