Electronic Brake Control System; Traction Control System (Tcs); Anti-Lock Brake System (Abs) - Jeep 2011 WK2 Grand Cherokee Owner's Manual

WARNING! (Continued)
• Be sure the parking brake is fully disen-
gaged before driving; failure to do so can
lead to brake failure and an accident.
• Always fully apply the parking brake when
leaving your vehicle, or it may roll and
cause damage or injury. Also be certain to
leave the transmission in PARK. Failure to
do so may allow the vehicle to roll and
cause damage or injury.
CAUTION!
If the "Brake Warning Light" remains on with
the parking brake released, a brake system
malfunction is indicated. Have the brake sys-
tem serviced by an authorized dealer imme-
diately.
ELECTRONIC BRAKE CONTROL
SYSTEM
Your vehicle is equipped with an advanced
electronic brake control system that includes
the Anti-Lock Brake System (ABS), Traction
Control System (TCS), Brake Assist System
(BAS), Electronic Roll Mitigation (ERM), and
Electronic Stability Control (ESC). All five of
these systems work together to enhance ve-
hicle stability and control in various driving
conditions.
Also, your vehicle is equipped with Trailer Sway
Control (TSC), Hill Start Assist (HSA), Brake
Lock Differential (BLD), Ready Alert Braking,
Rain Brake Support and, if it has four-wheel
drive with the MP 3023 two-speed transfer
case, Hill Descent Control (HDC).

Anti-Lock Brake System (ABS)

This system aids the driver in maintaining ve-
hicle control under adverse braking conditions.
The system controls hydraulic brake pressure
to prevent wheel lock-up and help avoid skid-
ding on slippery surfaces during braking.
WARNING!
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can it
increase the traction afforded by prevailing
road conditions. The ABS cannot prevent ac-
cidents, including those resulting from exces-
sive speed in turns, driving on very slippery
surfaces, or hydroplaning. The capabilities of
an ABS-equipped vehicle must never be ex-
ploited in a reckless or dangerous manner
which could jeopardize the user's safety or the
safety of others.

Traction Control System (TCS)

This system monitors the amount of wheel spin
of each of the driven wheels. If wheel spin is
detected, brake pressure is applied to the
slipping wheel(s) and engine power is reduced
to provide enhanced acceleration and stability.
A feature of the TCS system, 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 sys-
