Hill Start Assist (Hsa); Electronic Roll Mitigation (Erm) - Jeep 2015 Cherokee Operating Information Manual

WARNING! (Continued)
on the vehicle, nor can it increase the trac-
tion afforded by prevailing road conditions.
BAS cannot prevent collisions, including
those resulting from excessive speed in
turns, driving on very slippery surfaces, or
hydroplaning. The capabilities of a BAS-
equipped vehicle must never be exploited in
a reckless or dangerous manner, which
could jeopardize the user's safety or the
safety of others.

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 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
maneuvers. It cannot prevent wheel lift due to
other factors, such as road conditions, leaving
the roadway, or striking objects or other ve-
hicles.
NOTE:
ERM is disabled anytime the ESC is in "Full
Off" mode. Refer to Electronic Stability Con-
trol (ESC) 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. Electronic Roll Mitigation (ERM) can-
not prevent all wheel lift or rollovers, espe-
cially those that involve leaving 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 Start Assist (HSA)

The HSA system is designed to help the driver
accelerate the vehicle from a complete stop while
on an incline. If the driver releases the brake while
stopped on an incline, HSA will continue to hold
the brake pressure for a short period. If the driver
does not apply the throttle before this time ex-
pires, the system will release brake pressure and
the vehicle will roll down the hill as normal. The
system will release brake pressure in proportion
to amount of throttle applied.
The following conditions must be met in order
for HSA to activate:
• The vehicle must be stopped.
• The vehicle must be on a 7% (approximate)
grade or greater hill.
• The gear selection must match vehicle uphill
direction (i.e., vehicle facing uphill is in for-
ward gear; vehicle backing uphill is in RE-
VERSE gear).
• For vehicles equipped with an automatic
transmission, the HSA will work in REVERSE
gear and all forward gears. The system will
not activate if the transmission is in PARK.
