Differential (BLD), functions similar to a
self-locking differential and controls the
wheel spin across a driven axle. If one
wheel on the same 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.

BAS (Brake Assist System)
The BAS is designed to optimise the
braking capability car during emergency
braking manoeuvres. 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
complements the Anti-Lock braking
system (ABS). Applying 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 light
The red warning light or symbol
will turn on when the ignition device is
turned to the ENGINE position and may
stay on for as long as four seconds.
If the warning light or symbol remains
on, or it turns on while driving, the
braking system is not working correctly.
Contact a Jeep Dealership as soon as
possible to have it repaired. If the
warning light does not come on when the
ignition device is turned to the ENGINE
position, contact a Jeep Dealership
immediately to have it repaired.
DST (Dynamic Steering Torque) SYSTEM
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 car instability. The torque
that the steering wheel receives is
only meant to help the driver achieve
optimal steering behaviour in order to
reach/maintain car stability. The only
notification the driver receives that the
feature is active is the torque applied to
the steering wheel.
NOTE The DST system is only meant
to help the driver achieve the correct
course of action through small torques
on the steering wheel, which means the
effectiveness of the DST system is highly
dependent on the drivers sensitivity and
overall reaction to the applied torque. It
is very important to understand that this
feature will not steer the car, meaning
the driver is still responsible for steering
the car.
EBD (Electronic Brake Force Distribution)
SYSTEM
This system 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 car
instability, and to prevent the rear axle
from entering ABS before the front axle.
ERM (Electronic Rollover Mitigation)
SYSTEM
This system calculates the potential for
wheel lift by monitoring the driver's
steering wheel input and the speed of
the car. When variations in steering
wheel rotation and car speed, that could
potentially cause the wheels to lift off
the ground, are detected, the system
applies the brakes appropriately and if
required reduces the engine power in
order to reduce the possibility of wheels
lifting. The ERM system limits the
possibility of the wheels lifting off the
ground during extreme manoeuvres but it
cannot always prevent all wheel lift or
rollovers, especially those that involve
leaving the roadway or striking objects or
other cars.
