gether to enhance both vehicle stability and
control in various driving conditions.
Your vehicle may also be equipped with Ready
Alert Braking (RAB), Rain Brake Support (RBS),
Trailer Sway Control (TSC), and Dynamic Steer-
ing Torque (DST).
Traction Control System (TCS)
This system monitors the amount of wheel spin
of each of the driven wheels. If wheel spin is
detected, the TCS may apply brake pressure to
the spinning wheel(s) and/or reduce vehicle
power to provide enhanced acceleration and
stability. A feature of the TCS, Brake Limited
Differential (BLD), functions similar to a limited
slip differential and controls the wheel spin
across a driven axle. If one wheel on a driven
axle is spinning faster than the other, the system
will apply the brake of the spinning wheel. This
will allow more vehicle torque to be applied to
the wheel that is not spinning. BLD may remain
enabled even if TCS and ESC are in a reduced
mode.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s
braking capability during emergency braking
maneuvers. The system detects an emergency
braking situation by sensing the rate and
amount of brake application and then applies
optimum pressure to the brakes. This can help
reduce braking distances. The BAS comple-
ments the anti-lock brake system (ABS). Apply-
ing the brakes very quickly results in the best
BAS assistance. To receive the benefit of the
system, you must apply continuous braking
pressure during the stopping sequence, (do not
“pump” the brakes). Do not reduce brake pedal
pressure unless braking is no longer desired.
Once the brake pedal is released, the BAS is
deactivated.
WARNING!
The Brake Assist System (BAS) cannot pre-
vent the natural laws of physics from acting
on the vehicle, nor can it increase the traction
afforded by prevailing road conditions. BAS
cannot prevent collisions, including those re-
sulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning.
The capabilities of a BAS-equipped vehicle
must never be exploited in a reckless or
dangerous manner, which could jeopardize
the user’s safety or the safety of others.
Brake System Warning Light
The red “Brake System Warning Light” will turn
on when the ignition is turned to the ON/RUN
mode and may stay on for as long as four
seconds.
If the “Brake System Warning Light” remains on
or comes on while driving, it indicates that the
brake system is not functioning properly and
that immediate service is required. If the “Brake
System Warning Light” does not come on when
the ignition is turned to the ON/RUN mode, have
the light repaired as soon as possible.
Dynamic Steering Torque (DST)
Dynamic Steering Torque is a feature of the ESC
and Electric Power Steering (EPS) modules that
provides torque at the steering wheel for certain
driving conditions in which the ESC module is
detecting vehicle instability. The torque that the
steering wheel receives is only meant to help
the driver realize optimal steering behavior in
order to reach/maintain vehicle stability. The
only notification the driver receives that the
feature is active is the torque applied to the
steering wheel.
NOTE:
The DST feature is only meant to help the driver
realize the correct course of action through
small torques on the steering wheel, which
means the effectiveness of the DST feature is
highly dependent on the driver’s sensitivity and
overall reaction to the applied torque. It is very
important to realize that this feature will not steer
the vehicle, meaning the driver is still respon-
sible for steering the vehicle.
Electronic Brake Force Distribution (EBD)
This 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)
This system anticipates the potential for wheel
lift by monitoring the driver’s steering wheel
