SAFETY 177
Traction Control System (TCS)
The Traction Control System (TCS) 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 engine 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 engine torque to be applied to the wheel that
is not spinning. BLD may remain enabled even if TCS and
Electronic Stability Control (ESC) are in a reduced mode.
Rain Brake Support (RBS)
Rain Brake Support (RBS) may improve braking perfor-
mance in wet conditions. It will periodically apply a small
amount of brake pressure to remove any water buildup on
the front brake rotors. It functions when the windshield
wipers are in LO or HI speed. When Rain Brake Support is
active, there is no notification to the driver and no driver
interaction is required.
Ready Alert Braking (RAB)
Ready Alert Braking (RAB) may reduce the time required to
reach full braking during emergency braking situations. It
anticipates when an emergency braking situation may occur
by monitoring how fast the throttle is released by the driver.
The EBC will prepare the brake system for a panic stop.
Hill Descent Control (HDC) — If Equipped
Hill Descent Control (HDC) is intended for low speed
off-road driving while in 4L Range. HDC maintains vehicle
speed while descending hills during various driving situa-
tions. HDC controls vehicle speed by actively controlling the
brakes.
HDC Has Three States:
1. Off (feature is not enabled and will not activate).
2. Enabled (feature is enabled and ready but activation
conditions are not met, or driver is actively overriding
with brake or throttle application).
3. Active (feature is enabled and actively controlling vehicle
speed).
