The base price includes cloth-covered seating for five with manual lumbar adjustment for the front seats, and a second-row seat that is split 60/40 and can be folded down to expand the cargo floor. Also standard are a tilt-adjustable steering column, power windows and locks, remote keyless entry, an audio system with a CD player, cruise control, air conditioning, daytime running lights, fog lights, an electronic rearview mirror with temperature and compass readings, and a year's subscription of the OnStar telematics system. Base H3 models roll on 265/75R16 Goodyear all-terrain tires mounted on 16-inch wheels, and come with a full-size spare tire.

Safety features that come standard include StabiliTrak electronic stability control, antilock brakes (ABS), traction control, frontal and side-impact airbags (torso protection) for the driver and front-seat passenger, and a tire-pressure monitoring system. Side airbag curtains ($495) are optional and we recommend them for the head protection they can provide to you and your passengers in the event of a side impact or rollover. New child safety locks for the rear doors were introduced during the '07 model year, so don't assume a particular vehicle has them without checking.
