Short answer: On an LT, the usual build is Cold Weather + Driver Confidence + Convenience, and they require each other. On RS, adaptive cruise comes only in the Adaptive Cruise & Sound Package, which requires the sunroof plus Convenience and Driver Confidence. ACTIV includes Convenience and Driver Confidence.
Prices are MSRP before destination. 2027 Trailblazer Limited prices are from GM order data; new 2027 prices are from Chevrolet's preproduction announcement (Oct 2026). Confirm final pricing and destination on the window sticker.

On the new 2027
Chevrolet says adaptive cruise, front and rear park assist, Blind Zone Steering Assist and Rear Cross Traffic Braking become standard; an AutoSense power liftgate, wireless charging, heated seats and wheel and a panoramic sunroof (RS) become available.
