Standard safety features on the Sierra 2500HD are limited, but hitch guidance and General Motors' Teen Driver system are included.
Front and rear parking sensors, lane departure warning, and blind-spot monitoring are available on the Sierra, SLE, SLT, and AT4 trims as part of the $890 Driver Alert Package I.
On the SLT and AT4, a surround view camera, a bed view camera, and a 15-inch head-up display require the $2,125 Technology Package. The SLT and AT4 also make the Driver Alert Package II available for $645, which brings automatic emergency braking, forward collision warning, and lane departure warning, among other features.
The range-topping Denali trim adds automatic emergency braking, front and rear parking sensors, rear cross-traffic alert, lane departure warning, blind-spot monitoring, and forward collision warning as standard. The Technology Package is still available for $1,875.
