The driver's and right front passenger's frontal airbags are designed to inflate in moderate to severe frontal or near-frontal crashes. But they are designed to inflate only if the impact exceeds a predetermined deployment threshold. Deployment thresholds take into account a variety of desired deployment and non-deployment events and are used to predict how severe a crash is likely to be in time for the airbags to inflate and help restrain the occupants. Whether your frontal airbags will or should deploy is not based on how fast your vehicle is traveling. It depends largely on what you hit, the direction of the impact and how quickly your vehicle slows down.
Frontal airbags may inflate at different crash speeds. For example:
| • | If the vehicle hits a stationary object, the airbags could inflate at a different crash speed than if the vehicle hits a moving object. |
| • | If the vehicle hits an object that deforms, the airbags could inflate at a different crash speed than if the vehicle hits an object that does not deform. |
| • | If the vehicle hits a narrow object (like a pole), the airbags could inflate at a different crash speed than if the vehicle hits a wide object (like a wall). |
| • | If the vehicle goes into an object at an angle, the airbags could inflate at a different crash speed than if the vehicle goes straight into the object. |
The frontal airbags (driver and right front passenger) are not intended to inflate during vehicle rollovers, rear impacts, or in many side impacts.
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. Inflation is determined by what the vehicle hits, the angle of the impact, and how quickly the vehicle slows down.
The airbag system is designed to work properly under a wide range of conditions, including off-road usage. Observe safe driving speeds, especially on rough terrain. As always, wear your safety belt. See Off-Road Driving for more tips on off-road driving.
Single Stage vs. Dual Stage Airbags
Depending on the weight of your vehicle, you will have either "Single Stage Airbags" or "Dual Stage Airbags." Vehicles that have a passenger sensing system also have dual stage airbags. If the rearview mirror in your vehicle has a passenger airbag status indicator, your vehicle has the passenger sensing system and therefore, it has dual stage airbags. If the rearview mirror in your vehicle does not have a passenger airbag status indicator, then your vehicle does not have the passenger sensing system and it has single stage airbags. See Passenger Airbag Status Indicator or Passenger Sensing System .
Single Stage Airbags
If your vehicle has frontal airbags with single stage deployment and your vehicle goes straight into a wall that does not move or deform, the threshold level is about 13 to 16 mph (20 to 25 km/h). The threshold level can vary, however, with specific vehicle design, so that it can be somewhat above or below this range.
Dual Stage Airbags
If your vehicle has frontal airbags with dual stage deployment, the amount of restraint will adjust according to crash severity. Your vehicle has electronic frontal sensors which help the sensing system distinguish between a moderate and a more severe frontal impact. For moderate frontal impacts, these airbags inflate at a level less than full deployment. For more severe frontal impacts, full deployment occurs. If the front of your vehicle goes straight into a wall that does not move or deform, the threshold level for the reduced deployment is about 10 to 16 mph (16 to 25 km/h), and the threshold level for a full deployment is about 20 to 30 mph (32 to 48 km/h). The threshold level can vary, however, with specific vehicle design, so that it can be somewhat above or below this range.
Vehicle's with dual stage airbags also have special sensors which enable the sensing system to monitor the position of both the driver and passenger front seats. The seat position sensor provides information which is used to determine if the airbags should deploy at a reduced level or at full deployment.
