Safety system 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 replaced by such "under-ride"
collisions.

• Front air bags may not inflate in
rollover accidents because front air
bag deployment would not provide
additional occupant protection.
However, if equipped with side impact
and curtain air bags, the air bags may
inflate in a rollover, when it is detected
by the rollover sensor.
Also, side and curtain air bags may
inflate when the vehicle is rolled over
by a side impact collision, if the vehicle
is equipped with side impact air bags
and curtain air bags.

• 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.
