2013 JEEP GRAND CHEROKEE differential

Anti-Lock Brake System (ABS)
This system aids the driver in maintaining vehicle control
under adverse braking conditions. The system controls
hydraulic brake pressure to prevent wheel lock-up and
help avoid skidding on slippery surfaces during braking.
Refer to “Anti-Lock Brake System” in “Starting and
Operating” for further information.
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 collisions, including those result-
ing from excessive speed in turns, driving on very
slippery surfaces, or hydroplaning. The capabilities of
an ABS-equipped vehicle must never be exploited 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
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. This feature remains active even if
ESC system is in the “Partial Off” mode. Refer to “Elec-
tronic Stability Control (ESC)” in this section for further
information.
474 STARTING AND OPERATING

WARNING!
In the ESC “Full Off” mode, the engine torque
reduction and stability features are cancelled. There-
fore, the enhanced vehicle stability offered by ESC is
unavailable.
NOTE: When the ESC is switched OFF, a feature of the
system remains active. This feature controls wheel spin
across an axle quite similarly to a limited slip differential.
If one wheel on an axle is spinning faster than the other,
the system will apply the brake of the spinning wheel
and allow more engine torque to be applied to the wheel
that is not spinning. To improve the vehicle’s traction
when driving with tire chains, or when starting off in
deep snow, sand, or gravel, it may be desirable to switch
to the “Partial Off” mode by momentarily pressing the
“ESC Off” switch.
WARNING!
With the ESC switched OFF, the enhanced vehicle
stability offered by ESC is unavailable. In an emer-
gency evasive maneuver, the ESC system will not
engage to assist in maintaining stability. The “Full
Off” ESC mode is intended for off-highway or off-
road only.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an exces-
sively swaying trailer and will take the appropriate
actions to attempt to stop the sway. The system may
reduce engine power and apply the brake of the appro-
priate wheel(s) to counteract the sway of the trailer. TSC
will become active automatically once an excessively
swaying trailer is recognized. No driver action is re-
quired. Note that TSC cannot stop all trailers from
