The 2009 Chevrolet Avalanche is a full-size crew-cab pickup with a removable rear window and exclusive midgate. There are four trim levels: LS, LT1, LT2 and premium LTZ. The basic LS features a composite cargo bed, a removable three-piece cargo cover, full power accessories, a front 40/20/40-split bench seat with center storage, cloth trim, a power driver seat with manual lumbar control, an auto-dimming rearview mirror, Bluetooth, basic OnStar capability and a stereo with a single-CD player, an auxiliary jack and satellite radio. The LT1 is similar to the LS, but has standard front bucket seats, rear audio controls and enhanced OnStar with turn-by-turn navigation.Moving up to the LT2 package provides dual-zone automatic climate control, power-adjustable pedals, a six-CD changer, rear park assist and remote vehicle starting. The top-drawer LTZ offers 20-inch wheels, chrome exterior accents, an adaptive suspension, rain-sensing wipers, heated and cooled leather seats and a premium Bose audio system. Most of these upper-trim-level features are available as options on the lower trims.
Add the Z71 Off Road Package and you get specialized springs and shock absorbers, upgraded 18-inch off-road tires, an automatically locking rear differential, front recovery hooks, a skid plate and a high-capacity air cleaner. The Z71 looks different too, thanks to large color-keyed wheel flares, an aggressive front fascia and chrome assist steps.
Depending on the trim level, other stand-alone or packaged options include a navigation system, power running boards, 20-inch wheels, an integrated rearview camera, a rear-seat DVD entertainment system and a sunroof. This year's heavy-duty towing package includes an integrated trailer brake controller.
