Chevrolet has just launched an ad campaign to promote its distinction as the first carmaker to integrate Siri into its vehicles.

Chevrolet announced in November last year that it would be integrating Siri into its Spark and Sonic LTZ and RS car models. Then last month, the 2013 car models made their debut, equipped with Chevrolet’s MyLink infotainment system with Siri Eyes Free integration.

And now, Chevrolet has released “Buttons,” a TV ad featuring the Chevrolet Sonic and the “button to end all buttons.”

The end-all button in question is none other than the special steering wheel button that activates Siri Eyes Free integration on Chevrolet’s MyLink system. Upon activation, drivers can ask Siri questions and initiate commands without taking their eyes off the road.

As noted by MacRumors:

iSpot.tv founder and CEO Sean Muller tells us that the ad first aired last Thursday on VH1′s morning Jump Start block, with the site’s tracking showing that the ad has already aired 82 times on national TV networks.

You can also check out a more detailed demonstration of the feature in the video below, with my colleague Dom interviewing Brad of Chevrolet at this year’s CES.

Siri Eyes Free integration was introduced by Apple at last year’s Worldwide Developer Conference. Apple’s car manufacturing partners are BMW, Mercedes, Land Rover, Jaguar, Audi, Toyota, Chrysler, Honda, Hyundai, and, of course, Chevrolet’s parent company, General Motors.
