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 Lim-
ited Differential (BLD), functions similar to a limited
slip differential and controls 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. Refer to “Electronic Stability Con-
trol (ESC)” for further information.
ELECTRONIC ROLL MITIGATION (ERM)
This system anticipates the potential for wheel lif t by
monitoring the driver’s steering wheel input and the
speed of the vehicle. When ERM determines that the
rate of change of 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. ERM will only intervene during very severe or
evasive driving maneuvers. 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 vehicles.
WARNING!
Many factors, such as vehicle loading,
road con
ditions, and driving conditions,
influence the chance that wheel lift or rollover
may occur. 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 exploited in a reckless or dangerous
manner, which could jeopardize the user's safety
or the safety of others.
ELECTRONIC STABILITY CONTROL (ESC)
This system enhances directional control and stability
of the vehicle under various driving conditions. ESC
corrects for over-steering and under-steering the ve-
hicle by applying the brake of the appropriate wheel.
Engine power may also be reduced to help the vehicle
maintain the desired path.
The ESC uses sensors in the vehicle to determine the
path that the driver intends to steer the vehicle and
compares it to the actual path of the vehicle. When the
actual path does not match the intended path, the ESC
