Hill Descent Control (Hdc) - If Equipped - Jeep Compass 2015 Operating Information Manual

ing wheel angle and vehicles speed are suffi-
cient to potentially cause wheel lift, it applies the
brake of the appropriate wheel and may also
reduce engine power to lessen the chance that
wheel lift will occur. ERM will only intervene
during very severe or evasive driving maneu-
vers.
ERM can only reduce the chance of wheel lift
occurring during severe or evasive driving ma-
neuvers. It can not prevent wheel lift due to
other factors such as road conditions, leaving
the roadway or striking objects or other
vehicles.
NOTE:
Anytime the ESC system is in the "Full Off"
mode, ERM is disabled. 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
control 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 shift
lever in LOW or REVERSE. Refer to "Safe
Off-Road Driving" in "Starting and Operating" for
further information.
(Continued)
When HDC is properly enabled,
the "Hill Decent Control Light" in
the instrument cluster will be
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 pressing and holding the "ESC Off" button for
five seconds. Refer to "Electronic Stability Con-
trol (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 indicates
