Electronic Brake Force Distribution (EBD)
Electronic Brake Force Distribution (EBD)
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)
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.
Electronic Stability Control (ESC)
This 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 posi-
tion.
Understeer — when the vehicle is turning less
than appropriate for the steering wheel posi-
tion.
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 TCS 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 vehi-
cles. 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.
