Asc light on

what is an asc light?

My best guess is that this warning light has something to do with the stability control (anti-skid) system on that car.

But why take my word for it?. Open the glove compartment, take out the Owner’s Manual, and read the information that GM provided regarding this warning light.

When all else fails, read the directions.

It’s your Automatic Stability Control. The system helps to minimize a loss of control when needed.
