All redesigned Chevrolet Tahoe models include forward-collision warning with pedestrian detection and automatic emergency braking. The latter system works by first warning of a potential frontal collision. If necessary, the vehicle can then automatically apply the brakes to prevent or lessen the impact of a frontal crash. As mentioned before, though optional, the Driver Alert Package ($790) is recommended. It adds lane-keeping assist, blind-spot monitoring with rear cross-traffic alert and rear parking sensors. Note that those enhanced safety features are standard on the Premier and High Country trims. Also available on the High Country is adaptive cruise control, which can pace the vehicle ahead. Crash-test ratings for the new Chevrolet Tahoe are still to be determined.
