WARNING!
Many factors, such as vehicle loading,
road conditions, and driving conditions,
influence the chance that wheel lift or
rollover may occur. Electronic Roll Mitiga-
tion (ERM) cannot prevent all wheel lift or
rollovers, especially those that involve
leaving the roadway or striking objects or
other vehicles. The capabilities of an
ERM-equipped vehicle must never be ex-
ploited in a reckless or dangerous manner,
which could jeopardize the user's safety or
the safety of others.
Traction Control System (TCS)
This system monitors the amount of wheel
spin of each of the driven wheels. If wheel
spin is detected, brake pressure is applied to
the slipping wheel(s) and engine power is
reduced to provide enhanced acceleration
and stability. A feature of the TCS system,
Brake Limited Differential (BLD), functions
similar to a limited slip differential and con-
trols the wheel spin across a driven axle. If
one wheel on a driven axle is spinning faster
than the other, the system will apply the
brake of the spinning wheel. This will allow
more engine torque to be applied to the wheel
that is not spinning. This feature remains
active even if TCS and ESC are in the “Partial
Off” mode or the “Full Off” mode. Refer to
“Electronic Stability Control (ESC)” in this
section for further information.
Dynamic Steering Torque (DST)
The DST function uses the integration of the
ESC system with the electric power steering
to increase the safety level of the whole car.
In critical situations (understeering, over-
steering, braking with different grip condi-
tions), through the DST function the ESC
system controls the steering to implement an
additional torque contribution on the steering
wheel, to suggest the most correct maneuver
to the driver. The coordinated action of
brakes and steering increases the safety and
car control feeling.
NOTE:
The DST is a driving aid system and does not
replace the driver’s actions while driving the
car.
Hill Descent Control (HDC) — If Equipped
HDC is intended for low speed off road driv-
ing while in 4WD Low Range. HDC maintains
vehicle speed while descending hills during
various driving situations. HDC controls ve-
hicle speed by actively controlling the brakes.
HDC has three states:
1. Off (feature is not enabled and will not
activate).
