Safety features of your vehicle
• 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 "under-ride" situation
because deceleration forces that are
detected by sensors may be signifi-
cantly reduced by such “under-ride”
collisions.
• Air bags may not inflate in rollover acci-
dents because air bag deployment
would not provide protection to the
occupants.
However, if equipped with side impact
or curtain air bags, the air bag(s) may
inflate when the vehicle is rolled over
by a side impact collision.
• Air bags may not inflate if the vehicle
collides with objects such as utility
poles or trees, where the point of
impact is concentrated to one area and
the full force of the impact is not deliv-
ered to the sensors.
