2023 JEEP CHEROKEE differential

STARTING AND OPERATING87
Shifting Out Of 4X4 LOW
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the
ignition in the ON/RUN position and the engine running,
shift the transmission into NEUTRAL (N), and push the
4WD LOW button once. The 4WD LOW indicator light in the
instrument cluster will flash and go out when the shift is
complete.
NOTE:
If shift conditions/interlocks are not met, a message
will flash from the instrument cluster display with
instructions on how to complete the requested shift
Úpage 63.
 Shifting into or out of 4WD LOW is possible with the
vehicle completely stopped; however, difficulty may
occur due to the mating clutch teeth not being properly
aligned. Several attempts may be required for clutch
teeth alignment and shift completion to occur. The
preferred method is with the vehicle rolling 0 to 3 mph
(0 to 5 km/h). If the vehicle is moving faster than
3 mph (5 km/h), the 4WD system will not allow the
shift.
REAR ELECTRONIC LOCKER SYSTEM —
I
F EQUIPPED
The Rear Electronic 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 Electronic Locker System
To activate the Rear Electronic Locker System, the
following conditions must be met:

1. The 4WD system must be in 4WD LOW.

2. The ignition in the ON/RUN position and the engine
running.
3. Vehicle speed must be below 15 mph (24 km/h). 4. To engage the Rear Electronic Locker, push the REAR LOCK button once.

Rear Lock Button

Deactivating The Rear Electronic Locker System
To deactivate the Rear Electronic Locker System, the
following conditions must be met:

1. Rear Electronic Locker must be engaged, and the REAR LOCK indicator light on.

2. The ignition in the ON/RUN position and the engine running.
3. To disengage Rear Electronic Locker, push the REAR LOCK button once.
NOTE:
It may also be necessary to drive slowly steering back
and forth to complete engagement and disengage -
ment of the Electronic Locker.
 When engaging Rear Electronic Locker, the indicator
lights in the instrument cluster and on the REAR LOCK
button will begin to flash. When the shift is complete
the REAR LOCK indicator lights will remain on.
 When disengaging Rear Electronic Locker, the indi -
cator lights in the instrument cluster and on the REAR
LOCK button will begin to flash. When the shift is
complete the REAR LOCK indicator lights will remain
off.
 Shifting into or out of Rear Electronic Locker is possible
with the vehicle completely stopped; however, difficulty
may occur due to the mating clutch teeth not being
properly aligned. Several attempts may be required for
clutch teeth alignment and shift completion to occur.
The preferred method is for the vehicle to be rolling,
below 15 mph (24 km/h), while including right and left
steering maneuvers to allow for the clutch teeth to
align.
 The Rear Electronic Locker System must be disen -
gaged prior to taking the vehicle out of 4WD LOW
range. If 4WD LOW shift conditions/interlocks are not
met, a message will flash from the instrument cluster
display with instructions on how to complete the
requested shift.

150SAFETY
Disabling SSC
SSC will deactivate and be disabled if any of the following
conditions occur:
The driver pushes the SSC button.
 The driveline is shifted out of 4WD Low.
 The parking brake is applied.
 The driver door opens.
 The vehicle is driven greater than 20 mph (32 km/h)
for greater than 70 seconds.
 The vehicle is driven greater than 40 mph (64 km/h)
(SSC exits immediately).
Feedback To The Driver:
The instrument cluster has an SSC icon and the SSC
button has an LED which offers feedback to the driver
about the state SSC is in.
 The cluster icon and button lamp will illuminate and
remain on solid when SSC is enabled or activated. This
is the normal operating condition for SSC.
 The cluster icon and button lamp will flash for several
seconds then extinguish when the driver pushes the
SSC button but enable conditions are not met.
 The cluster icon and button lamp will flash for several
seconds then extinguish when SSC disables due to
excess speed.
 The cluster icon and button lamp will flash then extin -
guish when SSC deactivates due to overheated brakes.
Traction Control System (TCS)
The 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 similarly 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 reduced modes.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an
excessively swaying trailer and will take the appropriate
actions to attempt to stop the sway.
NOTE:
TSC cannot stop all trailers from swaying. Always use
caution when towing a trailer and follow the trailer tongue
weight recommendations
Úpage 114.
When TSC is functioning, the ESC Activation/Malfunction
Indicator Light will flash, the engine power may be reduced
and you may feel the brakes being applied to individual wheels to attempt to stop the trailer from swaying. TSC is
disabled when the ESC system is in the “Partial Off” or
“Full Off” modes.
AUXILIARY DRIVING SYSTEMS
BLIND SPOT MONITORING (BSM) —
I
F EQUIPPED
BSM uses two radar sensors, located inside the rear
fascia/bumper, to detect highway licensable vehicles
(automobiles, trucks, motorcycles, etc.) that enter the
blind spot zones from the rear/front/side of the vehicle.

Rear Detection Zones

WARNING!
SSC is only intended to assist the driver in controlling
vehicle speed when driving in off road conditions. The
driver must remain attentive to the driving conditions
and is responsible for maintaining a safe vehicle speed.
WARNING!
If TSC activates while driving, slow the vehicle down,
stop at the nearest safe location, and adjust the trailer
load to eliminate trailer sway.
