Electronic Brake Force Distribution (EBD)
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 Anti-Lock Brake System
(ABS) before the front axle.
Electronic Roll Mitigation (ERM)
ERM anticipates the potential for wheel lift by
monitoring the driver's steering wheel input and
the speed of the vehicle. When Electronic Roll
Mitigation (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 any time the ESC is in "Full Off"
mode (if equipped). For a complete explanation
of the available ESC modes, see Ú page 307.
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.
Electronic Stability Control (ESC)
ESC enhances directional control and stability
of the vehicle under various driving conditions.
Electronic Stability Control (ESC) corrects for
oversteering or understeering of the vehicle by
applying the brake of the appropriate wheel(s)
to counteract the above conditions. Engine
power may also be reduced to help the vehicle
maintain the desired path.
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.
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.
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.
