Participating is easy: you have to own a digital OnStar-equipped vehicle and press the blue OnStar button in your vehicle from now through May 31, 2011. The best thing is that you don't even need to be a subscriber to enter.
"More than 6 million customers currently take advantage of OnStar's advanced technology while they're on the road," said Terry Inch, director of subscriber services. "Yet there are many more drivers out there who may not realize all the services OnStar offers, like having access to a live advisor at the push of a button or getting monthly emails with key information specific to their vehicle that can help them save money."
According to General Motors, over the past 15 years, OnStar Advisors have answered 346 million button pushes, responded to more than 160,000 vehicle crashes, unlocked more than 5 million doors remotely, provided 2.6 million subscribers with roadside assistance and routed customers' turn by turn to their destination more than 70 million times.
"The 'Push On' sweepstakes is our way to remind drivers with OnStar in their vehicles, just how powerful the system is, yet so easy to use," said Sam Mancuso, OnStar chief marketing officer. "Just push a button and you're connected."
