How do you activate the traction control on a Chevrolet impala 2007?

The 2007 Chevrolet Impala doesn't have a button to turn traction control (TC) on or off. The system is automatically active. If it's malfunctioning, it will likely illuminate a warning light on the dashboard (often an icon depicting a car skidding). If that light is on, you should have it checked by a mechanic as the system may need repair.
