I don't know if this has been asked before..but what does VDC on or off mean?? I just noticed that after having my car for 4 months,well 3 of those months it's been parked..any info would be appreciated

 

Well, it's in the manual, but it stands for "vehicle dynamic control"....stops your car from sliding/spinning/etc.

With it off, you can spin your tires all day long.

Seriously, you should read the manual cover to cover, you will learn alot about your car!
