Air bag inflation conditions
ODN8039048LODN8039048L
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.
ODN8A039049ODN8A039049
ODN8039050ODN8039050
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 of impact resulting from a side
impact collision.
Although the driver’s and front
passenger’s air bags are designed to
inflate only 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 only in side
impact collisions or rollover situations,
but they may inflate in other collisions
if the side impact sensors detect a
sufficient impact.
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
ODN8039051LODN8039051L
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.

03
3-55
ODN8039052LODN8039052L
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.
ODN8A039053ODN8A039053
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 may
inflate depending on the severity of
impact.
ODN8039059ODN8039059
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.
ODN8039054ODN8039054
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.

CAUTION
• The system does not actually detect
objects or people in the rear seat. By
using a rear door opened and closed
history, the system indicates that
there may be something in the rear
seat.
• The rear door opened and closed
history will be initialized only when
the doors are locked after turning off
the engine. Therefore, there could be
alarms even though the back doors
are locked.
ex) When you get in and drive your vehicle without locking the doors after
the alarm sounds, there could be the
alarm sounds if you turn off the engine
and open the driver’s seat door.
WARNING
It does not use the actual sensors but it
provides the alarm sounds by checking
the rear door lock/unlock status as a
reminder.
