ELECTRONIC STABILITY CONTROL (ESC)
The ESC stability system is an optional
feature for ABS-equipped vehicles that
reduces the risk of rollovers and loss of
control. The ESC system features include
the RSP Roll Stability Program and Yaw
Control.
The RSP system counteracts the tendency
of a vehicle to tip over while changing
direction (typically, while turning).
To reduce the risk of rollover, the RSP
system detects potential rollover conditions
and slows the vehicle both by reducing
engine throttle (and hence, engine torque)
and by applying service brakes as needed at
the appropriate wheels.
During an RSP system intervention, you can
always use your service brake pedal to
increase the braking pressure that will be
applied. However, if you were to apply less
braking pressure than needed or even if you
release the brake pedal entirely during an
intervention, the RSP system will continue to
apply the necessary amount of braking
pressure automatically to the appropriate
wheels to mitigate a potential rollover.
Yaw Control is a feature that reduces the
risk of loss of control. If a vehicle’s tires start
to slide during a turn, Yaw Control
counteracts the tendency of that vehicle to
spin (or yaw), thereby reducing the risk of
loss of control. Many factors, including road
conditions, load distribution and driving
behavior, can contribute to the development
of a spin.
WARNING
During an RSP system intervention, the
vehicle automatically decelerates . The
RSP system can slow the vehicle with or
without you applying the brake pedal,
and even when you are applying the
throttle .
!
WARNING
In the case where a vehicle equipped with
the ESC system pulls a trailer, the latter
must be equipped with ABS.
