ous driving situations. HDC controls vehicle
speed by actively controlling the brakes.
HDC has three states:
1. Off (feature is not enabled and will not acti-
vate).
2. Enabled (feature is enabled and ready but
activation conditions are not met, or driver is
actively overriding with brake or throttle ap-
plication).
3. Active (feature is enabled and actively con-
trolling vehicle speed).
Enabling HDC
HDC is enabled by pressing the HDC switch,
but the following conditions must also be met to
enable HDC:
•
Driveline is in 4WD Low Range
•
Vehicle speed is below 5mph (8 km/h)
•
Parking brake is released
•
Driver 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 by using the paddle shifter. The
following summarizes the HDC set speeds:
•
P = No set speed. HDC may be enabled but
will not activate.
•
R = 0.6 mph (1 km/h)
•
N = 1.2 mph (2 km/h)
•
1st = 0.6 mph (1 km/h)
•
2nd = 1.2 mph (2 km/h)
•
3rd = 1.8 mph (3 km/h)
•
4th = 2.5 mph (4 km/h)
•
5th = 3.1 mph (5 km/h)
•
6th = 3.7 mph (6 km/h)
•
7th = 4.3 mph (7 km/h)
•
8th = 5.0 mph (8 km/h)
NOTE:
•
During HDC the +/- paddle shifter input is
used for HDC target speed selection and
will put the transmission into ERS but will
not affect the gear chosen by the trans-
mission unless in Driver Override. During
HDC the transmission will shift appropri-
ately for the driver-selected set speed and
corresponding driving conditions.
•
HDC performance is influenced by the Ter-
rain Select mode. This difference may be
notable to the driver and may be perceived
as a varying level of aggressiveness.
Driver Override:
The driver may override HDC activation with
throttle or brake application at any time. While in
driver override the transmission will be in ERS
which is a top gear limiter and the vehicle will
shift from 1st through the gear that is being
displayed.
