What the Hill Descent Control Light Means on a GMC Canyon
On the GMC Canyon, 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?
Urgency level for this indicator on the GMC Canyon: low. Reading the colour is the fastest gut-check — a red symbol asks you to stop and investigate quickly, while amber or yellow means schedule a check soon rather than immediately. Green and blue symbols are simply telling you a system is active. Whatever the colour, the safest habit is to note when the Hill Descent Control Light appeared, how the GMC Canyon is behaving, and whether the light is steady or flashing, because a flashing warning almost always means act now.
