Getting into the back seat is simpler because the passenger doesn't have to duck under belts, and the belts fit the same no matter how the front seats are adjusted. Seat travel is about one-third greater than the old truck. Cupholders big enough to hold any drink fold out from the center. A Driver Message Center monitors 18 functions and warns if the transmission gets too hot, as it might during towing. Heating and cooling capacity has been increased by 40 percent, yet the sound has been reduced.
Heat ducts direct warm air to rear-seat passengers' feet.
The forward view is panoramic. Side mirrors and side windows are both larger than the old truck. The third way the Sierra differs from last year's truck is its hydroformed frame composed of three distinct sections. It is 28 pounds lighter than the old one, is stronger and absorbs more energy in a crash. A side benefit is that it should be easier and less costly to repair crash damage.
