Hill Descent
Control (HDC)
If equipped, HDC can be used when
driving downhill. It sets and
maintains vehicle speed while
descending a very steep incline in a
forward or reverse gear.
The HDC switch is on the center
stack, below the climate controls.
Press
5 to enable or disable HDC.
Vehicle speed must be below
60 km/h (37 mph).
The HDC light displays on the
instrument cluster when enabled.
HDC can maintain vehicle speeds
between 4 and 30 km/h (3 and
19 mph) on an incline greater than
or equal to a 10% 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. Smaller
HDC speed control adjustments are
accomplished using the cruise up or
down buttons. Each tap of the
+RES will increase the set speed by
0.8 km/h (0.5 mph), while each tap
of the SET– will decrease the set
speed by 0.8 km/h (0.5 mph). This
adjusted speed becomes the new
set speed.
