•The cluster icon and switch lamp will flash for several
seconds then extinguish when the driver presses the
HDC switch but enable conditions are not met.
• The cluster icon and switch lamp will flash for several
seconds then extinguish when HDC deactivates due to
excess speed.

stop and HDC will activate again once the brakes have
cooled sufficiently.
