2018 JEEP CHEROKEE differential

For vehicles not equipped with an instrument
cluster display, perform the following steps:
1. Center the steering wheel (front wheelspointing straight forward).
2. Shift the transmission into PARK.
3. Apply the parking brake.
4. Start the engine.
5. Rotate the steering wheel slightly more than one-half turn to the left.
6. Push the “ESC Off” button located in the lower switch bank below the climate con-
trol four times within 20 seconds. The
“ESC Off Indicator Light” should turn on
and turn off two times.
7. Rotate the steering wheel back to center and then an additional slightly more than
one-half turn to the right.
8. Turn the ignition to the OFF mode and then back to ON. If the sequence was
completed properly, the “ESC Off Indica-
tor Light” will blink several times to con-
firm HSA is disabled.
9. Repeat these steps if you want to return this feature to its previous setting.Towing With HSA
HSA will also provide assistance to mitigate
roll back while towing a trailer.
WARNING!
• If you use a trailer brake controller withyour trailer, the trailer brakes may be
activated and deactivated with the brake
switch. If so, there may not be enough
brake pressure to hold both the vehicle
and the trailer on a hill when the brake
pedal is released. In order to avoid roll-
ing down an incline while resuming ac-
celeration, manually activate the trailer
brake or apply more vehicle brake pres-
sure prior to releasing the brake pedal.
• HSA is not a parking brake. Always apply
the parking brake fully when exiting your
vehicle. Also, be certain to place the
transmission in PARK.
• Failure to follow these warnings can re-
sult in a collision or serious personal
injury.
Traction Control System (TCS)
This system 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 re-
duce engine power to provide enhanced ac-
celeration and stability. A feature of the TCS,
Brake Limited Differential (BLD), functions
similar to a limited slip differential and con-
trols 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 en-
abled even if TCS and ESC are in a reduced
mode.
Electronic Stability Control (ESC)
This system enhances directional control and
stability of the vehicle under various driving
conditions. ESC corrects for oversteering or
understeering of the vehicle by applying the
brake of the appropriate wheel(s) to assist in
counteracting the oversteer or understeer
condition. Engine power may also be reduced
to help the vehicle maintain the desired path.

5. Shift the transmission into NEUTRAL.
6. Using a ballpoint pen or similar object,push and hold the recessed power transfer
unit NEUTRAL (N) button (located by the
selector switch) for four seconds. The
light behind the NEUTRAL (N) symbol
will blink, indicating shift in progress. The
light will stop blinking (stay on solid)
when the shift to NEUTRAL (N) is
complete. 7. After the shift is completed and the NEU-
TRAL (N) light stays on, release the NEU-
TRAL (N) button.
8. Start the engine.
9. Release the parking brake.
10. Shift the transmission into REVERSE.
11. Release the brake pedal (and clutch pedal on manual transmissions) for five
seconds and ensure that there is no
vehicle movement.
12. Shift the transmission to NEUTRAL.
13. Apply the parking brake.
14. Shift the automatic transmission into PARK, or place manual transmission in
gear (NOT in Neutral). Turn the engine
OFF, and remove the key fob.
Repeat steps 1-7 to shift out of NEUTRAL.Rear Electronic Locker (E-Locker) System
— If Equipped
The Rear E-Locker System features a me-
chanical 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 in the ON mode and the engine running.
3. Vehicle speed must be below 15 MPH (24 km/h).
4. To engage Rear E-Locker, push 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.
