You wouldn't use it. Most of people don't. It didn't know what it was for the first few months... It's a feature that's usually found on more luxury cars... kind of funny to see it on an Aveo. I like the facelift of the new one, It's that I wasn't able to get one for under 4k as I got mine with only 28k miles on it, otherwise I'd go for it.Originally Posted by petrified.rabbit
