Roof-rail airbags are not intended to inflate in rear impacts. Both roof-rail airbags will deploy when either side of the vehicle is struck or if the sensing system predicts that the vehicle is about to roll over, or in a severe frontal impact. Your vehicle has a seat position sensor which enables the sensing system to monitor the position of the driver's seat. The seat position sensor provides information that is used to determine if the airbags should deploy at a reduced level or at full deployment. In any particular crash, no one can say whether an airbag should have inflated simply because of the damage to a vehicle or because of what the repair costs were. For frontal airbags, inflation is determined by what the vehicle hits, the angle of the impact, and how quickly the vehicle slows down. For roof-rail airbags, deployment is determined by the location and severity of the side impact. In a rollover event, roof-rail airbag deployment is determined by the direction of the roll. What Makes an Airbag Inflate? In a deployment event, the sensing system sends an electrical signal triggering a release of gas from the inflator. Gas from the inflator fills the airbag causing the bag to break out of the cover and deploy. The inflator, the airbag, and related hardware are all part of the airbag module. Frontal airbag modules are located inside the steering wheel and instrument panel. For vehicles with roof-rail airbags, there are airbag modules in the ceiling of the vehicle, near the side windows that have occupant seating positions. How Does an Airbag Restrain? In moderate to severe frontal or near frontal collisions, even belted occupants can contact the steering wheel or the instrument panel. In moderate to severe side collisions, even belted occupants can contact the inside of the vehicle. Airbags supplement the protection provided by safety belts. Frontal airbags distribute the force of the impact more evenly over the occupant's upper body, stopping the occupant more gradually. Roof-rail airbags distribute the force of the impact more evenly over the occupant's upper body. 1-68

Roof-rail airbags are not intended to inflate in rear

impacts. Both roof-rail airbags will deploy when either

side of the vehicle is struck or if the sensing system

predicts that the vehicle is about to roll over, or in

a severe frontal impact.

Your vehicle has a seat position sensor which enables

the sensing system to monitor the position of the

driver’s seat. The seat position sensor provides

information that is used to determine if the airbags

should deploy at a reduced level or at full deployment.

In any particular crash, no one can say whether an

airbag should have inflated simply because of the

damage to a vehicle or because of what the repair costs

were. For frontal airbags, inflation is determined by

what the vehicle hits, the angle of the impact, and how

quickly the vehicle slows down. For roof-rail airbags,

deployment is determined by the location and severity of

the side impact. In a rollover event, roof-rail airbag

deployment is determined by the direction of the roll.

What Makes an Airbag Inflate?

In a deployment event, the sensing system sends

an electrical signal triggering a release of gas from the

inflator. Gas from the inflator fills the airbag causing

the bag to break out of the cover and deploy. The

inflator, the airbag, and related hardware are all part of

the airbag module.

Frontal airbag modules are located inside the

steering wheel and instrument panel. For vehicles

with roof-rail airbags, there are airbag modules in the

ceiling of the vehicle, near the side windows that

have occupant seating positions.

How Does an Airbag Restrain?

In moderate to severe frontal or near frontal collisions,

even belted occupants can contact the steering wheel or

the instrument panel. In moderate to severe side

collisions, even belted occupants can contact the inside

of the vehicle.

Airbags supplement the protection provided by safety

belts. Frontal airbags distribute the force of the

impact more evenly over the occupant’s upper body,

stopping the occupant more gradually. Roof-rail airbags

distribute the force of the impact more evenly over

the occupant’s upper body.
