236 SAFETY
Electronic Roll Mitigation (ERM)
Electronic Roll Mitigation (ERM) 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
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.
NOTE:
ERM is disabled anytime the ESC is in "Full Off" mode (if
equipped). Refer to "Electronic Stability Control (ESC)" in
this section 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. ERM cannot prevent all wheel
lift or roll overs, 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)
Electronic Stability Control (ESC) enhances directional
control and stability of the vehicle under various driving
conditions. ESC corrects for oversteering or understeering of
the vehicle by applying the brake of the appropriate wheel(s)
to assist in counteracting the oversteer or understeer condi-
tion. Engine power may also be reduced to help the vehicle
maintain the desired path.
