Operation Manual

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 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 conditions, 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
applies the brake of the appropriate wheel to assist in
counteracting the condition of over-steer or under-
steer.
• Over-steer - when the vehicle is turning more than
appropriate for the steering wheel position.
• Under-steer - when the vehicle is turning less than
appropriate for the steering wheel position.
WARNING!
• Electronic Stability Control (ESC)
cannot prevent the natural laws of phys-
ics from acting on the vehicle, nor can it increase
the traction afforded by prevailing road condi-
tions.
