The 2010 Cadillac STS doesn't want for the latest features. All versions have standard climate control; AM/FM/XM/CD/MP3 audio systems; a heated, wood-trimmed steering wheel; and metallic and wood trim on the dash. Cars.com reports that power front seats, dual-zone automatic climate control, a keyless access system, an eight-speaker CD stereo, a power-adjustable steering wheel, and sonar rear parking sensors are all standard on the base STS Cadillac.
Available features include an Easy Key keyless entry system; Adaptive Remote Start system; a four-color head-up display (HUD); and heated and ventilated seats. OnStar turn-by-turn navigation is also an option, along with a moonroof and a heated steering wheel.
Most reviewers, including Kelley Blue Book, rave over the optional 15-speaker Bose 5.1 Surround Sound audio system, which "delivers great sound." But the STS's navigation system takes some heat. ConsumerGuide finds that "relatively few buttons" on the dash almost buries the functions on the radio and GPS, which can "complicate their use." Edmunds doesn't agree; they consider the "controls are straightforward and easy to use," though the memory setting procedure for many of the cabin controls are "confounding...frustrating and unnecessarily complicated."
On the well-equipped STS-V, the standard features list expands greatly. ForbesAutos lists "stiffer stabilizer bars and suspension springs, a quicker steering ratio, high-performance brakes, and a performance-tuned chassis," as distinct features, while Cars.com notes that the V's "10-spoke, painted aluminum-alloy wheels are exclusive." Edmunds tallies more standard features, such as "leather/suede upholstery," "heated leather-wrapped steering wheel," "power sunroof," and "navigation system w/voice recognition," while one of its very few options is a choice to delete the sunroof.
