Electronic Brake Force Distribution (EBD)
The Electronic Brake Force Distribution
(EBD) function manages the distribution of
the braking torque between the front and
rear axles, by limiting braking pressure to the
rear axle. This is done to prevent overslip of
the rear wheels to avoid vehicle instability,
and to prevent the rear axle from entering
ABS before the front axle.
Electronic Roll Mitigation (ERM)
The Electronic Roll Mitigation (ERM) 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 can
only reduce the chance of wheel lift occur
-
ring during severe or evasive driving maneu
-
vers; it cannot prevent wheel lift due to other
factors, such as road conditions, leaving the
roadway, 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.
Electronic Stability Control (ESC)
The Electronic Stability Control (ESC)
system 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
condition. Engine power may also be
reduced to help the vehicle maintain the
desired path.
ESC uses sensors in the vehicle to determine
the vehicle path intended by the driver and
compares it to the actual path of the vehicle.
When the actual path does not match the
intended path, ESC applies the brake of the
appropriate wheel to assist in counteracting
the oversteer or understeer condition.
Oversteer — when the vehicle is turning
more than appropriate for the steering
wheel position.
Understeer — when the vehicle is turning
less than appropriate for the steering
wheel position.
The “ESC Activation/Malfunction Indicator
Light” located in the instrument cluster will
start to flash as soon as the ESC system
becomes active. The “ESC Activation/
Malfunction Indicator Light” also flashes
when the Traction Control System is active.
If the “ESC Activation/Malfunction Indicator
Light” begins to flash during acceleration,
ease up on the accelerator and apply as little
throttle as possible. Be sure to adapt your
speed and driving to the prevailing road
conditions.
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.
