2016 JEEP CHEROKEE transmission

When servicing your rear brakes, it may be necessary for
you or your technician to push the rear piston into the
rear caliper bore. With the electric park brake system, this
can only be done after retracting the Electric Park Brake
actuator. Fortunately, actuator retraction can be done
easily by entering the Brake Service Mode through the
Uconnect Settings in your vehicle. This menu based
system will guide you through the steps necessary to
retract the EPB actuator in order to perform rear brake
service.
Service Mode has requirements that must be met in order
to be activated:
•The vehicle must be at a standstill.
• The park brake must be unapplied.
• The transmission must be in Park or Neutral.
While in service mode, the Electric Park Brake fault lamp
will flash continuously while the ignition switch is ON. When brake service work is complete, the following steps
must be followed to reset the park brake system to
normal operation:
•
Ensure the vehicle is at a standstill.
• Press the brake pedal with moderate force.
• Apply the Electric Park Brake Switch.
WARNING!
You can be badly injured working on or around a
motor vehicle. Do only that service work for which you
have the knowledge and the right equipment. If you
have any doubt about your ability to perform a service
job, take your vehicle to a competent mechanic.
518 STARTING AND OPERATING

•Park brake must be off.
• Driver door must be closed.
• The vehicle must be on a sufficient grade.
• The gear selection must match vehicle uphill direction
(i.e., vehicle facing uphill is in forward gear; vehicle
backing uphill is in REVERSE gear).
• HSA will work in REVERSE gear and all forward
gears. The system will not activate if the transmission
is in PARK or NEUTRAL. For vehicles equipped with
a manual transmission if the clutch is pressed HSA will
remain active.
WARNING!
There may be situations where the Hill Start Assist
(HSA) will not activate and slight rolling may occur,
(Continued)
WARNING! (Continued)
such as on minor hills or with a loaded vehicle, or
while pulling a trailer. HSA is not a substitute for
active driving involvement. It is always the driver ’s
responsibility to be attentive to distance to other
vehicles, people, and objects, and most importantly
brake operation to ensure safe operation of the ve-
hicle under all road conditions. Your complete atten-
tion is always required while driving to maintain
safe control of your vehicle. Failure to follow these
warnings can result in a collision or serious personal
injury.
Towing With HSA
HSA will also provide assistance to mitigate roll back
while towing a trailer.
524 STARTING AND OPERATING

WARNING!
•If you use a trailer brake controller with your
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 rolling down an
incline while resuming acceleration, manually ac-
tivate the trailer brake or apply more vehicle brake
pressure prior to releasing the brake pedal.
• HSA is not a parking brake. Always apply the
parking brake fully when leaving your vehicle.
Also, be certain to leave the transmission in PARK.
• Failure to follow these warnings can result in a
collision or serious personal injury.
Disabling And Enabling HSA
This feature can be turned on or turned off. To change the
current setting, proceed as follows:
• For vehicles equipped with the Electronic Vehicle
Information Center (EVIC) or Driver Information Dis-
play (DID), refer to “Electronic Vehicle Information
Center (EVIC)” or “Driver Information Display (DID)”
in “Understanding Your Instrument Panel” for further
information.
• If disabling HSA using Uconnect Settings, refer to
“Uconnect Settings” in “Understanding Your Instru-
ment Panel” for further information.
For vehicles not equipped with the EVIC/DID, perform
the following steps:
1. Center the steering wheel (front wheels pointing straight forward).
5
STARTING AND OPERATING 525

2. Shift the transmission into PARK.
3. Apply the parking brake.
4. Start the engine.
5. Rotate the steering wheel slightly more than one-halfturn to the left.
6. Push the “ESC Off” button located in the lower switch bank below the climate control four times within
twenty 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 slighty more than one-half turn to the right.
8. Turn the ignition switch to the OFF position and then back to the ON position. If the sequence was com-
pleted properly, the “ESC Off Indicator Light” will
blink several times to confirm HSA is disabled. 9. Repeat these steps if you want to return this feature to
its previous setting.
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
reduce engine power to provide enhanced acceleration
and stability. A feature of the TCS, Brake Limited Differ-
ential (BLD), functions similar to a limited slip differen-
tial 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 ESC are in a reduced mode.
526 STARTING AND OPERATING

Activating HDC
Once HDC is enabled it will activate automatically if
driven down a grade of sufficient magnitude. The set
speed for HDC is selectable by the driver, and can be
adjusted by using the gear shift +/-. The following
summarizes the HDC set speeds:
HDC Target Set Speeds
•P = No set speed. HDC may be enabled but will not
activate
• R = 0.6 mph (1 km/h)
• N = 1.2 mph (2 km/h)
• D = 0.6 mph (1 km/h)
• 1st = 0.6 mph (1 km/h)
• 2nd = 1.2 mph (2 km/h)
• 3rd = 1.8 mph (3 km/h) •
4th = 2.5 mph (4 km/h)
• 5th = 3.1 mph (5 km/h)
• 6th = 3.7 mph (6 km/h)
• 7th = 4.3 mph (7 km/h)
• 8th = 5.0 mph (8 km/h)
• 9th = 5.6 mph (9 km/h) – If Equipped
NOTE: During HDC the +/- shifter input is used for
HDC target speed selection but will not affect the gear
chosen by the transmission. When actively controlling
HDC the transmission will shift appropriately for the
driver-selected set speed and corresponding driving con-
ditions.
Driver Override
The driver may override HDC activation with throttle or
brake application at anytime.

STARTING AND OPERATING 535

•Vehicle speed is below 5 mph (8 km/h)
• Parking brake is released.
• Driver door is closed.
• Driver is not applying throttle.
Activating SSC
Once SSC is enabled it will activate automatically once
the following conditions are met:
• Driver releases throttle.
• Driver releases brake.
• Transmission is in any selection other than P.
• Vehicle speed is below 20 mph (32 km/h)
The set speed for SSC is selectable by the driver, and can
be adjusted by using the gear shift +/-. Additionally, the
SSC set speed may be reduced when climbing a grade and the level of set speed reduction depends on the
magnitude of grade. The following summarizes the SSC
set speeds:
SSC Target Set Speeds
•
1st = .6 mph (1 km/h)
• 2nd = 1.2 mph (2 km/h)
• 3rd = 1.8 mph (3 km/h)
• 4th = 2.5 mph (4 km/h)
• 5th = 3.1 mph (5 km/h)
• 6th = 3.7 mph (6 km/h)
• 7th = 4.3 mph (7 km/h)
• 8th = 5 mph (8 km/h)
• 9th = 5.6 mph (9 km/h) – If Equipped
• REVERSE = .6 mph (1 km/h)
538 STARTING AND OPERATING

•NEUTRAL = 1.2 mph (2 km/h)
• PARK = SSC remains enabled but not active
NOTE:
• During SSC the +/- shifter input is used for SSC target
speed selection but will not affect the gear chosen by
the transmission. While actively controlling SSC the
transmission will shift appropriately for the driver-
selected set speed and corresponding driving condi-
tions.
• SSC performance is influenced by the Terrain Select
mode. This difference may be notable to the driver and
may be perceived as a varying level of aggressiveness.
Driver Override:
The driver may override SSC activation with throttle or
brake application at any time. Deactivating SSC
SSC will be deactivated but remain available if any of the
following conditions occur:
•
Driver overrides SSC set speed with throttle or brake
application.
• Vehicle speed exceeds 20 mph (32 km/h) but remains
below 40 mph (64 km/h).
• Vehicle is shifted to PARK.
Disabling SSC
SSC will deactivate and be disabled if any of the follow-
ing conditions occur:
• The driver pushes the SSC switch.
• The driveline is shifted out of 4WD Low Range.
• The parking brake is applied.
• Driver door opens.
