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 gear shift lever.
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)
• D = 0.6 mph (1 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)
• 9th = 5.6 mph (9 km/h)
NOTE:
• During HDC the ERS +/- shifter input is
used for HDC target speed selection but
will not affect the gear chosen by the
transmission. During HDC the transmis-
sion will shift appropriately for the driver-
selected set speed and corresponding
driving conditions.
• HDC performance is influenced by the
Terrain Select mode. This difference may
be notable to the driver and may be per-
ceived as a varying
aggressiveness.
Driver Override:
The driver may override HDC activation with
throttle or brake application at anytime.
