Air bag inflation conditions
OTM030014
Front air bags
Front air bags are designed to inflate
in a fr
ontal collision depending on the
severity of impact of the front collision.
OTM030013
OTM030033
Side and curtain air bags
Side and curtain air bags are designed
t
o inflate when an impact is detected
by side collision sensors depending on
the severity, speed or angles of impact
resulting from a side impact collision.
Although the driver’s and front
passenger’s air bags are designed to
inflate in frontal collisions, they also may
inflate in other types of collisions if the
front impact sensors detect a sufficient
impact. Side and curtain air bags are
designed to inflate in side impact
collisions, but they may inflate in other
collisions if the side impact sensors
detect a sufficient impact.
Also, the side and curtain air bags are
designed to inflate when a rollover
is detected by a rollover sensor. (if
equipped with rollover sensor)
If the vehicle chassis is impacted by
bumps or objects on unimproved roads,
the air bags may deploy. Drive carefully
on unimproved roads or on surfaces not
designed for vehicle traffic to prevent
unintended air bag deployment.

Air bag non-inflation conditions
OTM030015
In certain low-speed collisions the air
bags may not deploy. The air bags are
designed not to deploy in such cases
because they may not provide benefits
beyond the protection of the seat belts.
OTM030016
Front air bags are not designed to inflate
in rear collisions, because occupants
are moved backward by the force of the
impact. In this case, inflated air bags
would not provide any additional benefit.
OTM030017
Front air bags may not inflate in side
impact collisions, because occupants
move in the direction of the collision,
and thus in side impacts, front air bag
deployment would not provide additional
occupant protection.
However, side and curtain air bags
and front center air bag may inflate
depending on the severity of impact.
OTM030034
In an angled collision, the force of impact
may direct the occupants in a direction
where the air bags would not be able to
provide any additional benefit, and thus
the sensors may not deploy any air bags.

OTM030018
Just before impact, drivers often brake
heavily. Such heavy braking lowers the
front portion of the vehicle causing it
to “ride” under a vehicle with a higher
ground clearance. Air bags may not
inflate in this “underride” situation
because deceleration forces that are
detected by sensors may be significantly
reduced by such “underride” collisions.
OTM030041
Front air bags may not inflate in
rollover accidents because front air bag
deployment would not provide additional
occupant protection.
However, the side and curtain air bags
and front center air bag may inflate in a
rollover situation, when it is detected by
the rollover sensor.
OTM030019
Air bags may not inflate if the vehicle
collides with objects such as utility poles
or trees, where the point of impact is
concentrated and the collision energy is
absorbed by the vehicle structure.
