Other notable new features for 2006 include the availability of a side-impact air bag system for first- and second-row outboard occupants, in addition to the standard dual-stage front driver and passenger air bags. The side-impact air bags are standard on Terraza CXL, and available on Terraza CX models.

With its ability to carry seven people in quiet comfort along with plenty of cargo, Terraza combines SUV styling and all-weather driving capability with the flexibility required by mid-van customers. Just as Rendezvous and Rainier have done in their respective segments, Terraza provides the Buick attributes of comfort, style, a silent ride and ample power.

Front-wheel drive is standard, while GM's exclusive Versatrak on-demand all-wheel drive system is available on both CX and CXL models to give Terraza even more capability. Front-wheel drive Terraza models include standard StabiliTrak, GM's advanced electronic stability control system that helps drivers maintain control during sudden maneuvers or low traction conditions. Traction control also is standard on FWD models.

Other standard features include a four-wheel anti-lock disc brake system, 17-inch wheels and tires, independent front and rear suspension and a 121-inch (308-cm) wheelbase, giving Terraza a smooth, car-like ride with excellent handling characteristics.
