590 STARTING AND OPERATING
Feedback to the driver:
The instrument cluster has a HDC icon and a HDC
switch which has an LED which offers feedback to the
driver about the state HDC is in.
• While HDC is Enabled or Active the gear position
typically associated with ERS manual mode will indi-
cate target set speed not the top gear limit which is
typical of ERS manual mode.
• The cluster icon and switch lamp will illuminate and
remain on solid when HDC is enabled or activated.
This is the normal operating condition for HDC.
• 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.
• The cluster icon and switch lamp will flash when HDC
deactivates due to overheated brakes. The flashing will
stop and HDC will activate again once the brakes have
cooled sufficiently.
WARNING!
HDC is only intended to assist the driver in control-
ling vehicle speed when descending hills. The driver
must remain attentive to the driving conditions and
is responsible for maintaining a safe vehicle speed.
