3. Active (feature is enabled and actively con-
trolling vehicle speed).
Enabling HDC
HDC is enabled by pushing the HDC switch, but
the following conditions must also be met to
enable HDC:
•
Driveline is in 4WD Low Range.
•
Vehicle speed is below 7.5 mph (12 km/h).
•
Electric Park Brake (EPB) is released.
•
Driver’s door is closed.
Activating HDC
Once HDC is enabled, it will activate automati-
cally if driven down a grade of sufficient magni-
tude (greater than approximately 8%). The set
speed for HDC is selectable by the driver and
can be adjusted within the thresholds by using
throttle or brake application.
Driver Override:
The driver may override HDC activation speed
with throttle or brake application at anytime.
Deactivating HDC
HDC will be deactivated but remain available if
any of the following conditions occur:
•
Driver overrides HDC set speed with a speed
exceeding 7.5 mph (12 km/h) but remains
below 25 mph (40 km/h).
•
Vehicle is on a downhill grade of insufficient
magnitude (less than approximately 8%), is
on level ground, or is on an uphill grade.
•
Vehicle is shifted to PARK.
Disabling HDC
HDC will be deactivated and disabled if any of
the following conditions occur:
•
The driver pushes the HDC switch.
•
The driveline is shifted out of 4WD Low
Range.
•
Driver’s door opens.
•
The vehicle is driven greater than 25 mph
(40 km/h) (HDC exits immediately.)
Feedback To The Driver:
The instrument cluster has an HDC icon and the
HDC switch has an LED which offer feedback to
the driver about the state HDC is in.
•
The cluster icon and switch lamp will illumi-
nate and remain solid when HDC is enabled
or activated. This is the normal operating
condition for HDC.
•
The switch lamp will flash for several seconds
then extinguish when the driver pushes the
HDC switch when enable conditions have not
been met.
The Hill Descent Switch is located within the
Selec-Terrain knob in the upper right position.
WARNING!
HDC is only intended to assist the driver in
controlling vehicle speed when descending
hills. The driver must remain attentive to the
driving conditions and is responsible for
maintaining a safe vehicle speed.
Hill Start Assist (HSA)
The HSA system is designed to mitigate roll
back from a complete stop while on an incline. If
the driver releases the brake while stopped on
an incline, HSA will continue to hold the brake
pressure for a short period. If the driver does not
apply the throttle before this time expires, the
system will release brake pressure and the
vehicle will roll down the hill as normal.
The following conditions must be met in order
for HSA to activate:
•
The feature must be enabled.
•
The vehicle must be stopped.
•
Park brake must be off.
•
Driver door must be closed.
•
The vehicle must be on a sufficient grade.
•
The gear selection must match vehicle uphill
direction (i.e., vehicle facing uphill is in for-
ward gear; vehicle backing uphill is in RE-
VERSE gear).
