2014 JEEP CHEROKEE differential

Rear Electronic Locker (E-Locker) System —
If Equipped
The Rear E-Locker System features a mechanical locking
rear differential to provide better traction in the 4WD
LOW position. The “REAR LOCK” button is on the
Selec-Terrain Knob.
Activating The Rear E-Locker
To activate the Rear E-Locker System, the following
conditions must be met:
1. The 4WD system must be in 4WD LOW.
2. The ignition switch in the ON position or the enginerunning.
3. Vehicle speed must be below 15 MPH (24 km/h).
4. To engage Rear E-Locker, press the REAR LOCK button once. Deactivating The Rear E-Locker System
To deactivate the Rear E-Locker System, the following
conditions must be met:
1. Rear E-Locker must be engaged, and the REAR LOCK
indicator light on.
2. The ignition switch in the ON position or the engine running.
3. To disengage Rear E-Locker, press the REAR LOCK button once.
NOTE:
• It may also be necessary to drive slowly steering back
and forth to complete engagement and disengagement
of the E-Locker.
442 STARTING AND OPERATING

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 TCS and ESC are in the “Partial Off” mode
or the “Full Off” mode. Refer to “Electronic Stability
Control (ESC)” in this section for further information.
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 sens-
ing 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 brake system (ABS). Applying the brakes very
quickly results in the best BAS assistance. To receive the
benefit of the system, you must apply continuous brak-
ing 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.
