SAFETY 123
Electronic Brake Force Distribution (EBD)
The 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 the 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 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, striking objects or other vehicles.
Electronic Stability Control (ESC)
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 these 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 position.
Understeer — when the vehicle is turning less than
appropriate for the steering wheel position.
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.
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.
WARNING!
Electronic Stability Control (ESC) cannot prevent the
natural laws of physics from acting on the vehicle, nor can
it increase the traction afforded by prevailing road condi-
tions. ESC cannot prevent accidents, including those
resulting from excessive speed in turns, driving on very
slippery surfaces, or hydroplaning. ESC also cannot
prevent accidents resulting from loss of vehicle control
due to inappropriate driver input for the conditions. Only
a safe, attentive, and skillful driver can prevent accidents.
The capabilities of an ESC equipped vehicle must never
be exploited in a reckless or dangerous manner which
could jeopardize the user’s safety or the safety of others.
Vehicle modifications, or failure to properly maintain
your vehicle, may change the handling characteris-
tics of your vehicle, and may negatively affect the
performance of the ESC system. Changes to the
steering system, suspension, braking system, tire
type and size or wheel size may adversely affect ESC
performance. Improperly inflated and unevenly worn
tires may also degrade ESC performance. Any vehicle
modification or poor vehicle maintenance that
reduces the effectiveness of the ESC system can
increase the risk of loss of vehicle control, vehicle
rollover, personal injury and death.
