Driving and Operating
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.
Press

to enable or disable HDC. Vehicle
speed must be below 50 km/h (31 mph).
The HDC light displays on the instrument
cluster when enabled.
HDC can maintain vehicle speeds between
3 and 22 km/h (2 and 14 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 22 and
60 km/h (14 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.

better suit preference by adjusting multiple
subsystems. Driver Mode availability and
affected vehicle subsystems are dependent

future ignition cycles. If the vehicle is in any
other mode, it will return to Tour Mode
when the vehicle is restarted. When a mode
