Safe Driving
■When front airbags should not deploy
Minor frontal crashes:  Front airbags were designed to supplement seat belts and 
help save lives, not to prevent minor scrapes, or even broken bones that might occur  
during a less than moderate-to-severe frontal crash.
Side impacts:  Front airbags can provide protection when a sudden deceleration 
causes a driver or front passenger to move towards the front of the vehicle. Side 
airbags and side curtain airbags have been specifically designed to help reduce the 
severity of injuries that can occur during a moderate-to-severe side impact which  
can cause the driver or passenger to move towards the side of the vehicle. 
Rear impacts:  Head restraints and seat belts are your best protection during a rear 
impact. Front airbags cannot provide any significant protection and are not designed  
to deploy in such collisions. 
Rollovers:  Seat belts and, in vehicles equipped with a rollover sensor, side airbags 
and side curtain airbags offer the best protection in a rollover. Because front airbags  
could provide little if any protection, they are not designed to deploy during a  
rollover. ■ When front airbags deploy with little or no visible damage
Because the airbag system senses sudden deceleration, a strong impact to the  
vehicle framework or suspension might cause one or more of the airbags to deploy. 
Examples include running into a curb, the edge of a hole, or other low fixed object  
that causes a sudden deceleration in the vehicle chassis. Since the impact is  
underneath the vehicle, damage may not be readily apparent. ■ When front airbags may not deploy, even though exterior damage  
appears severe
Since crushable body parts absorb crash energy during an impact, the amount of  
visible damage does not always indicate proper airbag operation. In fact, some  
collisions can result in severe damage but no airbag deployment because the airbags  
would not have been needed or would not have provided protection even if they 
had deployed.

Safe Driving
■When a side airbag deploys wi th little or no visible damage
Because the airbag systems senses sudden acceleration, a strong impact to the side  
of the vehicle's framework can cause a side airbag to deploy. In such cases, there  
may be little or no damage, but the side impact sensors detected a severe enough 
impact to deploy the airbag. ■ When a side airbag may not deploy, even though visible damage appears  
severe
It is possible for a side airbag to not deploy during an impact that results in 
apparently severe damage. This can occur when the point of impact was towards 
the far front or rear of the vehicle, or when the vehicle's crushable body parts  
absorbed most of the crash energy. In either case, the side airbag would not have  
been needed nor provided protection even if it had deployed.
