Safety and Technology The 2006 Hummer H3’s dual-stage front airbags include occupant sensing for front passengers and electronics can disable the passenger-side airbag when a small occupant or no passenger is present. Curtain airbags are optional and stretch to the beltline of both rows.

Aside from the 2006 Hummer H3’s robust ladder-type construction and all-steel body panels, several safety features work to protect occupants in the event of an accident. Dual-stage front airbags include occupant sensing for front passengers and electronics can disable the passenger-side airbag when a small occupant or no passenger is present. Curtain airbags are optional and stretch to the beltline of both rows. In addition to regular impacts, these units are also activated by a rollover sensing system for increased protection. Tire pressure monitoring and StabiliTrak stability control are also available.

Hummer’s electronically controlled full-time transfer case, regardless of the gear ratio, includes several modes of operation in the H3. For normal cruising, 4High-range Open should be engaged. When conditions deteriorate, or should you choose to foray into the backcountry, 4High-range Locked allows torque to be transferred to each axle, as needed. Locked 4Low-range should be used for difficult rock crawling or when traversing deep snow or sand. This mode also includes driver-selectable rear differential locking. With the available 4.03:1 gearing, this engineering boost provides crawling on par with the H1 and H2. Finally, Neutral allows the H3 to be towed flat.

But the H3 is not simply a terrain-busting machine, as evidenced by the four available stereo systems, XM satellite radio, and On Star telematics system. The top stereo includes a 6.5-inch touch-screen linked to a DVD-based navigation system, and includes separate slots for DVDs and CDs.
