Nothing major has been revised for the 2010 Chevrolet Avalanche, with changes including standard USB connectivity in the center console and the now-standard single-speed transfer case for 4WD-equipped models. A two-speed transfer case is optional. The 1LT package now includes dual-zone automatic climate control, power-adjustable pedals, remote vehicle start, and a heavy-duty locking rear differential. New exterior colors include Taupe Gray Metallic and Sheer Silver Metallic, both of which replace Dark Blue Metallic, Silver Birch Metallic, and Graystone Metallic.
