Hill Descent Control (HDC)
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.
HDC can be enabled or disabled on the
infotainment screen. Vehicle speed must be
below 35 km/h (22 mph).
The HDC light displays on the instrument
cluster when enabled.
HDC can maintain vehicle speeds between
1.
1 and 35 km/h (1 and 22 mph) on an incline
greater than or equal to a 10% grade. A blinking
HDC light indicates the system is actively
applying the brakes to maintain vehicle speed.
When HDC is activated, the initial HDC speed
is set to the current driving speed. It can be
increased or decreased by pressing +RES or
–SET on the steering wheel or by applying the
accelerator or brake pedal. This adjusted speed
becomes the new set speed.
HDC will remain enabled between 35 and 60
km/h (22 and 37 mph); however vehicle speed
cannot be set or maintained in this range. It
will automatically disable if the vehicle speed
is above 80 km/h (50 mph) or above 60 km/h
(37 mph) for at least 30 seconds. Press 5 again
to re-enable HDC.
Driver Mode Control
Driver Mode Control (DMC) allows the driver to
adjust the overall driving experience to better
suit driver preference by adjusting vehicle
systems to fit specific driving needs. Drive
mode availability and affected vehicle systems
are dependent on vehicle trim level, region, and
optional features.
