What this light means

This light means hill descent control (which automatically modulates brake pressure to control speed on steep descents, mainly off-road) is unavailable or has detected a fault.

Possible systems involved

Possible systems are not yet verified.

Common triggers

  • A brake-system sensor or module fault feeding this feature
  • A fault shared with the broader stability/traction control system

Check this before driving

  1. Use manual, low-gear braking technique on steep descents until resolved
  2. Avoid relying on this feature for steep off-road descents until confirmed working
  3. Have it scanned, especially if other stability lights are also on

Frequently asked questions

Is this only relevant off-road?

It is most relevant on steep, low-traction descents, which are more common off-road, but the underlying fault can be worth checking regardless of how the vehicle is used.
