The CTS comes in a single trim level but numerous option packages enable buyers to add varying levels of additional luxury- and sport-oriented features. Standard equipment includes leather seating, side and head-protecting side-curtain airbags, an eight-way power-adjustable driver seat, dual-zone climate control, a CD player, the OnStar communications system, ABS and traction control. Upgrades through the Luxury package include items like a power passenger seat, a two-driver memory package, heated front seats, HomeLink and wood trim on the steering wheel and shift lever. Additional options include a sunroof and an upgraded Bose audio package with a DVD-based navigation system and satellite radio.
