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 on page 366 for more tips on off-road driving. 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 on page 248 or Passenger Sensing System on page 103. 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. 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 96
