Driving and Operating
At speeds below 30 km/h, press
button
5
. The green control
indicator
5
will turn on in the
instrument panel. The green control
indicator
5
will flashes in the
instrument panel when the HDC is
in operation. HDC will neither
activate nor operate at speeds
above 30 km/h, even if the button is
pressed.
HDC can maintain vehicle speeds
between minimum speed of
approximately 7 km/h and 30 km/h
(manual transmission) or
approximately 4 km/h and 30 km/h
(automatic transmission) on an
incline greater than or equal to a 5%
grade. A blinking HDC light
indicates that the system is actively
applying the brakes to maintain
vehicle speed. When HDC is set,
that is the initial set speed. It can be
increased or decreased by applying
the accelerator or brake pedal. This
adjusted speed becomes the new
set speed. When enabled, if the
vehicle is at a speed above 30 km/h
and below than 50 km/h, the
message "Reduce Speed for Hill
Descent Control" will display
on DIC.
When the HDC is active and the
vehicle speed exceeds 30 km/h, the
green control indicator will turn off,
while the HDC function remains on
stand by.
Once the vehicle speed goes below
30 km/h, the green control indicator
will illuminate, indicating that the
system is activated again.
When the HDC is on stand by, and
the vehicle speed exceeds 50 km/h,
the HDC deactivates. Following this
the system will need to be
reactivated through the HDC switch
once the vehicle speed falls below
30 km/h.
Deactivation
While HDC is active and the vehicle
speed is below 30 km/h, press
button
5
to deactivate the system.
The green control indicator will turn
off indicating the system is no
longer active. The system will
automatically deactivate once the
vehicle speed exceeds 50 km/h.
System Protection
Operated continuously for long
periods of time may increase
temperatures within the brake
system. If this occurs the system will
be automatically put on hold,
temporarily disabling HDC.
In this mode, all other braking
functions will continue to operate
normally. When this occurs the
system gradually releases the
brakes and the green control
indicator will turn off.
Once the system returns to normal
operating temperatures, the system
will be able to be reactivated using
the HDC switch at speeds below
30 km/h as usual.
