• 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" in-
dicates the customer has elected to
have the Electronic Stability Control
(ESC) in a reduced mode.
Electronic Roll Mitigation (ERM)
This system anticipates the potential for wheel
lift by monitoring the driver's steering wheel
input and the speed of the vehicle. When ERM
determines that the rate of change of the steer-
ing wheel angle and vehicle's speed are suffi-
cient to potentially cause wheel lift, it then
applies the appropriate brake and may also
reduce engine power to lessen the chance that
wheel lift will occur. ERM can only reduce the
chance of wheel lift occurring during severe or
evasive driving maneuvers; it cannot prevent
wheel lift due to other factors, such as road
conditions, leaving the roadway, or striking ob-
jects or other vehicles.
NOTE:
ERM is disabled anytime the ESC is in "Full
Off" mode (if equipped). Refer to "Electronic
Stability Control (ESC)" in this section for a
complete explanation of the available ESC
modes.
WARNING!
Many factors, such as vehicle loading, road
conditions and driving conditions, influence
the chance that wheel lift or rollover may
occur. ERM cannot prevent all wheel lift or
roll overs, especially those that involve leav-
ing the roadway or striking objects or other
vehicles. The capabilities of an ERM-
equipped vehicle must never be exploited in
a reckless or dangerous manner which could
jeopardize the user's safety or the safety of
others.
Hill Descent Control (HDC) — If Equipped
This system maintains vehicle speed while de-
scending hills during off-road driving situations.
HDC will automatically apply the brakes to con-
trol downhill speed to between 4 mph (7 km/h)
and 6 mph (9 km/h) depending on terrain. The
system is activated by placing the vehicle in
"Off-Road" mode and placing the gear selector
in LOW or REVERSE. Refer to "Off-Road Driv-
ing Tips" in "Starting And Operating" for further
information.
When HDC is properly enabled, the
"Hill Decent Control Light" in the
instrument cluster
illuminated.
HDC has the capability to sense terrain and will
only activate when the vehicle is descending a
hill. It will not activate on level ground. If desired,
HDC can be fully deactivated by putting the
vehicle into ESC "Full Off" mode. This is done by
pushing and holding the "ESC Off" button for five
seconds. Refer to "Electronic Stability Control
(ESC)" in this section of the manual.
HDC operation can be overridden with brake
application to slow the vehicle down below the
HDC control speed. Conversely, if more speed
is desired during HDC control, the accelerator
pedal will increase vehicle speed like normal.
When either the brake or the accelerator is
released, HDC will control the vehicle back to
the original set speed.
HDC is only intended for low speed off-road
driving. At vehicle speeds above 31 mph
(50 km/h), HDC will no longer function. If the
"HDC Indicator Light" begins to flash, this indi-
cates that the brakes are getting too hot and the
vehicle should be stopped to allow the brakes to
cool.
