What the Hill Descent Control Light Means on a Citroen C4 Cactus
On the Citroen C4 Cactus, this symbol means hill descent control is engaged. It uses the brakes to manage speed downhill; it typically only works below a certain speed and turns off above it.
How Urgent Is the Hill Descent Control Light?
In terms of priority, treat this as a low concern on your Citroen C4 Cactus. The single most useful thing you can observe is whether the Hill Descent Control Light is steady or blinking: a steady light generally allows a careful drive to a safe location or a workshop, whereas a flashing light signals an active fault that can cause damage if you continue. Pay attention to changes in how the Citroen C4 Cactus drives, sounds, or smells, since those symptoms sharpen the diagnosis considerably.
