SAFETY 149
NOTE:
The “ESC Activation/Malfunction Indicator
Light” and the “ESC Off Indicator Light” come
on momentarily each time the ignition is
turned ON.
Each time the ignition is turned ON, 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.
The “ESC OFF Indicator Light” indi-
cates the customer has elected to
have the Electronic Stability Control
(ESC) in a reduced mode.
Hill Descent Control (HDC) — If Equipped
Hill Descent Control (HDC) is intended for low
speed off road driving while in 4L Range. HDC
maintains vehicle speed while descending 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 acti-
vate)
2. Enabled (feature is enabled and ready but
activation conditions are not met, or driver
is actively overriding 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 following conditions must also be met to
enable HDC:
Driveline is in 4L Range
Vehicle speed is below 5 mph (8 km/h)
Park brake is released
Driver door is closed (If doors are attached,
then door must be closed. If doors are
detached, then driver seatbelt must be
buckled)
Activating HDC
Once HDC is enabled it will activate automati-
cally if driven down a grade of sufficient magni-
tude. The set speed for HDC is selectable by the
driver, and can be adjusted by using the gear
shift +/-. The following summarizes 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)
