TRAILERING

The Sierra and Yukon are both made with trailering capability in mind. Beyond the strength and capability built into these powerful GMCs, there’s technology. The combination helps create a confident, comfortable driving experience. Whether you’re a novice setting off on your first adventure or a seasoned pro, the available in-vehicle trailering technology can help make the process easy.

The available In-Vehicle Trailering App1,2 — standard on Sierra AT4/AT4X, Denali/Denali Ultimate and available on Yukon AT4 Ultimate and Denali Ultimate — offers a smart approach to towing with integrated tools. You can access the app through the trailering icon on the vehicle’s center display.

Here is some of what the in-vehicle trailering app has to offer:

  • Custom trailer profiles that can be created based on trailer name, trailer type and trailer hitch type
  • Trailer Light Sequence, which includes automatic lighting test sequence
  • Maintenance reminders
  • Step-by-step pre-departure checklists
  • Steps to help launch your boat (Yukon only)
