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.
OBH038062
Front air bags may not inflate in 
rollover accidents because front air bag 
deployment would not provide additional 
occupant protection.
 Information
With rollover sensor
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.
OIK030082
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.
