CAPABILITY

To help with positioning, after backing up to a trailer hitch using available Hitch Guidance with Hitch View,^† Sierra Heavy Duty will automatically apply the electric parking brake upon shifting into Park to avoid unintentional rolling.

Prevents movement when shifting out of park on a hill and moving a foot from brake to accelerator pedal by automatically applying brakes at each wheel for an extended period of time while trailering.

Eases driver’s steering effort when manoeuvering at low speeds, reduces the steering effort needed to return the heavy-duty truck to centre, and adapts to crowned road surfaces, reducing the need to correct steering over long stretches of uneven road. It includes enhancements to help with driving response, especially when trailering or when carrying a heavy load.

Sierra is the first heavy-duty truck in its class to offer a 2-speed AutoTrac™ transfer case with an active automatic 4WD setting, which provides seamless shifting between two- and four-wheel drive based on road conditions.
