2. Sierra HD Pro Safety

The Sierra HD Pro Safety package takes assistive driving to the next level by using a combination of functions to monitor your Sierra’s surroundings. Functions in the Sierra HD Pro Safety package include:

  • Following Distance Indicator
  • Lane Departure Warning

This package contains a hitch, a 2.5-inch receiver hitch, a trailering hitch platform, a 7-wire electrical harness, a 7-pin sealed connector, and Hitch Guidance. Hitch Guidance comes in handy when it’s time to attach your trailer to the hitch because it shows you an in-cabin display of your hitch with a digital guideline for aligning the two perfectly.

Pair your phone to the truck to make hands-free phone calls or send text messages as you drive.
