2007 H3 incorporates structural enhancements and advanced safety systems to assist in crash avoidance and protection, including a reinforced passenger compartment safety cage that helps provide protection in the event of side and frontal impacts. The strong, rigid steel structure surrounds the passenger compartment, runs from the A-pillars to the roof rail, back to the D-pillars and includes the bottom rocker panels, under-floor longitudinals and frame. The all-steel body panels and exceptionally strong frame further help protect occupants in a collision. The fully welded, ladder-type frame optimizes crash performance, in addition to standing up to rigorous off-road requirements.

Additional crash protection is provided by a standard frontal dual-stage air bag system. 2007 HUMMER H3 has GM's Passenger Sensing System, which uses weight-sensing technology to turn the front passenger air bag on or off as appropriate. If the sensor system detects an unoccupied front passenger seat or the presence of a smaller occupant, the front passenger air bag is designed to automatically turn off so it would not deploy in the event of a frontal collision. Even with this system, GM strongly recommends restraining child passengers 12 and under in an appropriate child seat or, for older children, lap-and-shoulder belts in the second or third row of the vehicle.

Optional roof rail-mounted, side curtain air bags drop down to the belt line to help provide head and rollover protection for the driver and front passenger. A rollover protection sensing system also helps protect occupants against impending rollovers by triggering side curtain air bags to increase the likelihood of occupant containment in a rollover event. Seat belt pretensioners help keep occupants in the proper position, reducing their likelihood making contact with the inside of the vehicle.

*Horsepower and torque SAE certified. A new voluntary power and torque certification procedure developed by the SAE Engine Test Code committee was approved March 31, 2005 . This procedure (J2723) ensures fair, accurate ratings for horsepower and torque by allowing manufacturers to certify their engines through third-party witness testing. GM was the first auto manufacturer to begin using the procedure and expects to use it for all newly rated engines in the future.
