    The air bag is designed to inflate in moderate-to-severe frontal or near-frontal crashes. The air bag will inflate only if the impact speed is above the system's designed "threshold level." If your vehicle goes straight into a wall that doesn't move or deform, the threshold level is about 14 to 18 mph (23 to 29 km/h). The threshold level can vary, however, with specific vehicle design, so that it can be somewhat above or below this range. If your vehicle strikes something that will move or deform, such as a parked car, the threshold level will be higher. Inflation is determined by the angle of the impact and the vehicle’s deceleration.

  • A:

    If the vehicle is equipped with seat-mounted side impact or roof rail-mounted head curtain air bags, those will deploy in a side impact. If the vehicle is equipped with rollover capable head curtain air bags, a rollover sensor will deploy the head curtain air bags in a rollover incident. The frontal air bags will not deploy in a side impact or rollover, unless there is also a front or front-corner impact of sufficient severity to trigger the frontal air bags. The air bags will not deploy in a rear impact.

    There are no specific child restraints that GM recommends or endorses, but we do have some information that might be helpful to you.

    GM's seats and safety belt systems are designed to accommodate child restraints. However, we cannot be certain that all child restraints will be compatible with GM vehicles. Our cars conform to SAE (Society of Automotive Engineers) J1819 standard, which is a recommended guideline for automotive safety belt and child restraint compatibility. Therefore, child restraints that conform to this standard will be more compatible with the seats and safety belt systems used in GM vehicles. Also, your GM dealer can install a tether anchor kit (at no charge to you) that will anchor front-facing child seats.

    We recommend you work with a child-safety seat manufacturer, or a local retail outlet that sells child restraint seats, for possible suggestions on what type of seat would be most appropriate for your needs. You could also take your child restraint to a checkup event or contact a local CPS technician for additional assistance. There are a couple of websites that have some good information on this topic.

    In addition, you might want to try checking with your local hospital, police department and fire department for any information they might have.
