2014 GMC Sierra Towing Technology

The 2014 GMC Sierra is available with technologies that will make life easier for those who need, or want, to tow stuff.
 
Whether you’re a contractor who needs to tow a trailer for work, or a sports enthusiast who needs to tow a trailer packed with all the must-have toys for an unforgettable weekend getaway, the 2014 GMC Sierra promises to make towing safer than ever.
 
GMC has packed the Sierra with technologies like Hill Start Assist, that automatically applies the brakes while you’re standing still on a grade to prevent the trailer from rolling backwards. It’s a great tool for touchy situations, like climbing out of a boat launch.
 
Then there’s the Tow-Haul mode, which is activated by a button on the shift lever. When engaged it “re-maps” the transmission’s shift points to allow you to take advantage of engine power, keeping in mind the extra weight you’re towing behind you.
 
When slowing down, Tow-Haul mode allows downshifts to happen sooner, which in turn promotes engine braking, while at the same time reducing brake wear, as well as controlling brake rotor temperatures.
 
To prevent the trailer from getting out of control, Trailer Sway Control works in conjunction with the truck’s own traction control system, sensing trailer sway, and taking proactive measures to avoid disaster by braking and/or reduced engine power to bring the trailer under control and keep it on its intended path.
 
It also uses the electric trailer brakes, when a trailer is plugged into the standard wiring harness of the truck. If you don’t like the way the Sierra applies the brakes, you can fine tune the setting with the Integrated Trailer Brake Controller, which allows the driver to modify trailer braking force based on the weight of a trailer.
