What the Hill Descent Control Light Means on a Chevrolet Aveo
The hill descent control light on a Chevrolet Aveo confirms the system is active, automatically holding a slow, steady speed on steep off-road or slippery descents so you can focus on steering.
How Urgent Is the Hill Descent Control Light?
How worried should you be? For the Hill Descent Control Light on a Chevrolet Aveo, the urgency is low. A good rule technicians rely on is 'colour plus behaviour': match the warning colour against how the car is actually performing.

Is It Safe to Drive With the Hill Descent Control Light On?
Whether it is safe to keep driving your Chevrolet Aveo with the Hill Descent Control Light on comes down to urgency (low) and behaviour. As a rule, if the light is red or flashing, or the Chevrolet Aveo is running poorly, stop somewhere safe and arrange help rather than pushing on.
