Does the VSA automatically turn itself on when you
start the car? There's a Triangle w/exclamation point
in it.

when I start the car on its not light up. but after I
press the button it lights up? When its light up
is it actually on or off?

 

It automatically comes on when you start the car. When you press the VSA OFF button, the ! light will illuminate telling you that the system is off.

However, when the system is on and the light blinks while driving it's telling you that the system is active at that time helping reduce wheelspin and/or unwanted lateral movement.
