trim level, available from 2002 to 2009, added extra luxury and convenience features to the base SLE trim, including a six-disc, in-dash CD changer, a Bose six-speaker premium amplified audio system, OnStar, polished aluminum-alloy wheels, luxury leather-trimmed seating surfaces, dual heated front bucket seats, Driver Information Center, faux wood interior trim panels, a universal garage door opener system with a travel note recorder, a dual-zone, automatic climate control system, and a driver's memory system for driver's seat, mirrors, and radio preset settings.
