Driving
• gear selection matches vehicle uphill
direction (i.e., vehicle facing uphill is
in forward gear; vehicle backing
uphill is in reverse gear).
HSA will work in R (Reverse) and all
forward gears when the activation
criteria have been met.
The system will not activate if the gear
is placed in N (Neutral) or P (Park).
Roll-Over Mitigation (ROM)
This system anticipates the potential
for wheel lift by monitoring the
driver's steering wheel input and the
speed of the vehicle. When ROM
determines that the rate of change of
5 the steering wheel angle and vehicle's
speed are sufficient 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.
ROM will only intervene during very
severe or evasive driving maneuvers.
ROM 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 and off-road conditions,
leaving the roadway, or striking
objects or other vehicles.

WARNING!
Many factors, suchas vehicle loading,
road and off-road conditions, and
driving conditions, influence the
chance that wheel lift or rollover may
occur. ROM cannot prevent all wheel
lift or roll-overs, especially those that
involve leaving the roadway or
striking objects or other vehicles. The
capabilities of a ROM-equipped
vehicle must never be exploited in a
reckless ordangerous manner, which
could jeopardize the user's safety or
the safety of others.
Trailer Sway Mitigation (TSM)
TSM uses sensors in the vehicle to
recognize an excessively swaying
trailer and will take the appropriate
actions to attempt to stop the sway.
The system may reduce engine power
and apply the brake of the
appropriate wheel(s) to counteract the
sway of the trailer. TSM will become
active automatically once an
excessively swaying trailer is
recognized.
TSM cannot stop all trailers from
swaying. Always use caution when
towing a trailer and follow the trailer
tongue weight recommendations.
Refer to "Trailer Towing" in this
section for further information. When
TSM is functioning, the "ESC
Activation/Malfunction Indicator
Light" will flash (see "Instrument
Cluster" in section "Dashboard
Instruments and Controls"), the engine
power may be reduced and you may
feel the brakes being applied to
individual wheels to attempt to stop
the trailer from swaying.
TSM is disabled when the ESC system is
partially deactivated (button
pressed, LED on).
WARNING!
If TSM activates while driving, slow
the vehicle down, stop at the nearest
safe location, and adjust the trailer
load to eliminate trailer sway.
Hill Descent Control (HDC)
HDC maintains vehicle speed while
descending hills during various driving
situations, by actively controlling the
brakes.
HDC is part of the ESC system and has
three possible states:
• Off: feature is not enabled and will
not activate.
