The ESC OFF Indicator Light indicates the
customer has elected to have the Electronic
Stability Control (ESC) in a reduced mode.
NOTE:
•
The ESC Activation/Malfunction Indicator Light and
the ESC OFF Indicator Light come on momentarily
each time the ignition is placed in the ON position.
•
Each time the ignition is place in the ON position,
the ESC system will be on even if it was turned off
previously.
•
The ESC system will make buzzing or clicking
sounds when it is active. This is normal; the sounds
will stop when ESC becomes inactive following the
maneuver that caused the ESC activation.
Hill Descent Control (HDC) — If Equipped
HDC is intended for low speed off-road driving while in
4WD Low. HDC maintains vehicle speed while descend-
ing hills during various driving situations. HDC controls
vehicle speed by actively controlling the brakes.
HDC has three states:
1. Off (feature is not enabled and will not activate).
2. Enabled (feature is enabled and ready but activation
conditions are not met, or driver is actively overrid-
ing with brake or throttle application).
3. Active (feature is enabled and actively controlling
vehicle speed).
Enabling HDC
HDC is enabled by pushing the HDC switch, but the fol-
lowing conditions must also be met to enable HDC:
•
The driveline is in 4WD Low.
•
The vehicle speed is below 5 mph (8 km/h).
•
The parking brake is released.
•
The driver door is closed. (If doors are attached,
then door must be closed. If doors are detached,
then driver seat belt must be buckled.)
Activating HDC
Once HDC is enabled it will activate automatically if
driven down a grade of sufficient magnitude. The set
speed for HDC is selectable by the driver, and can be
adjusted by using the gear shift +/-. The following sum-
marizes the HDC set speeds:
HDC Target 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) – If Equipped
NOTE:
During HDC the +/- shifter input is used for HDC target
speed selection, but will not affect the gear chosen by the
transmission. When actively controlling HDC the transmis-
sion will shift appropriately for the driver-selected set
speed and corresponding driving conditions.
Driver Override
The driver may override HDC activation with throttle or
brake application at any time.
Deactivating HDC
HDC will be deactivated but remain available if any of
the following conditions occur:
•
Driver overrides HDC set speed with throttle or
brake application.
•
Vehicle speed exceeds 20 mph (32 km/h) but
remains below 40 mph (64 km/h).
•
Vehicle is on a downhill grade of insufficient magni-
tude, 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 fol-
lowing conditions occur:
•
The driver pushes the HDC switch.
•
The driveline is shifted out of 4WD Low.
•
The parking brake is applied.
•
The driver door opens. (Driver door opens if doors
are attached or driver seat belt is unbuckled if doors
are detached.)
•
The vehicle is driven greater than 20 mph
(32 km/h) for greater than 70 seconds.
•
The vehicle is driven greater than 40 mph
(64 km/h) (HDC exits immediately).
•
HDC detects excessive brake temperature.
