When HDC is properly enabled, the message “HILL
DESCENT CONTROL” will appear in the EVIC and the
light in the switch will be illuminated. HDC will auto-
matically apply the brakes to control downhill speed
when necessary. HDC has the capability to sense terrain
and will only activate when the vehicle is descending a
hill. It will usually not activate on level ground.
The HDC speed may be adjusted by the driver to suit the
driving conditions. The speed corresponds to the trans-
mission gear selected.
•
1st = 1 mph (1.6 km/h)
•
2nd = 2.5 mph (4 km/h)
•
3rd = 4 mph (6 km/h)
•
4th = 5.5 mph (9 km/h)
•
5th = 7.5 mph (12 km/h)
•
REVERSE = 1 mph (1.6 km/h)
•
NEUTRAL = 2.5 mph (4 km/h)
•
PARK = HDC will not function
HDC also has the capability to sense rough terrain, and
will automatically adjust to a slightly slower set speed
(about 0.3 mph (0.5 km/h) than normal.
HDC operation can be overridden with brake application
to slow the vehicle down below the HDC control speed.
Conversely, if more speed is desired during HDC control,
the accelerator pedal will increase vehicle speed in the
usual manner. When either the brake or the accelerator is
released, HDC will control the vehicle back to the origi-
nal set speed.
