2010 GMC Terrain: Thumb-wheel Cruise Control

July 15, 2010

Our long-term 2010 GMC Terrain has an interesting cruise control setup on the face of its steering wheel. There's a one-way rocker Master switch, but the speed setting switch is a momentary two-way quarter-turn thumbwheel. I haven't seen this setup before.

When the Master switch is turned on, a white telltale in the tach illuminates. The telltale turns green when the cruise speed is set.

The speed setting thumbwheel works just fine: no better or worse than a rocker switch, although I would think it costs more than a rocker.

I believe GMC chose this route for design symmetry with the thumbwheel voice/audio control on the other side of the wheel, which has become increasingly popular.

On a related note, myself and others I've spoken with no longer use cruise control as a driver workload-reducing convenience.

We instead use it to avoid traffic citations.
