2014 JEEP CHEROKEE light

When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain, traveling into strong head winds, or
while towing heavy trailers), use the Electronic Range
Select (ERS) shift control (refer toElectronic Range Select
(ERS) Operation in this section) to select a lower gear
range. Under these conditions, using a lower gear range
will improve performance and extend transmission life
by reducing excessive shifting and heat buildup.
If the transmission operating temperature exceeds nor-
mal operating limits, the transmission controller may
modify the transmission shift schedule, reduce engine
torque, and/or expand the range of torque converter
clutch engagement. This is done to prevent transmission
damage due to overheating. If the transmission becomes extremely hot, the “Trans-
mission Temperature Warning Light” may illuminate and
the transmission may operate differently until the trans-
mission cools down.
During cold temperatures, transmission operation may
be modified depending on engine and transmission
temperature as well as vehicle speed. This feature im-
proves warm up time of the engine and transmission to
achieve maximum efficiency. Engagement of the torque
converter clutch, and shifts into 8th or 9th gear, are
inhibited until the transmission fluid is warm (refer to the
“Note” under “Torque Converter Clutch” in this section).
Normal operation will resume once the transmission
temperature has risen to a suitable level.
432 STARTING AND OPERATING

SPORT — IF EQUIPPED
This mode alters the transmission’s automatic shift
schedule for sportier driving. Upshift speeds are in-
creased to make full use of available engine power.
SPORT mode is activated using the rotary switch on the
center console. Refer toSelec-Terrainin this section for
further information.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission remains
in fourth gear regardless of which forward gear is
selected. PARK, REVERSE, and NEUTRAL will continue
to operate. The Malfunction Indicator Light (MIL) may be illuminated. Limp Home Mode allows the vehicle to be
driven to an authorized dealer for service without dam-
aging the transmission.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition switch to the LOCK/OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no
longer detected, the transmission will return to normal
operation.5
STARTING AND OPERATING 433

WARNING!
You or others could be seriously or fatally injured if
you leave the vehicle unattended with the power
transfer unit in the NEUTRAL (N) position without
first fully engaging the parking brake. The NEU-
TRAL (N) position disengages both the front and rear
drive shafts from the powertrain and will allow the
vehicle to move regardless of the transmission posi-
tion. The parking brake should always be applied
when the driver is not in the vehicle.
4WD LOW
This range is for low speed four-wheel drive. It provides
an additional gear reduction which allows for increased
torque to be delivered to both the front and rear wheels
while providing maximum pulling power for loose,
slippery road surfaces only. Do not exceed 25 mph
(40 km/h).NOTE:
Refer to “Selec-Terrain® – If Equipped” for fur-
ther information on the various positions and their
intended usages.
Shifting Procedures
Shifting Into 4WD LOW
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the
ignition switch in the ON position or the engine running,
shift the transmission into NEUTRAL, and press the
“4WD LOW” button once. The “4WD LOW” indicator
light in the instrument cluster will begin to flash and
remain on solid when the shift is complete.
438 STARTING AND OPERATING

NOTE:If shift conditions/interlocks are not met a mes-
sage will flash from the Electronic Vehicle Information
Center (EVIC) with instructions on how to complete the
requested shift. Refer to “Electronic Vehicle Information
Center (EVIC)” in “Understanding Your Instrument
Panel” for further information.
Shifting Out Of 4WD LOW
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the
ignition switch in the ON position or the engine running,
shift the transmission into NEUTRAL, and press 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 Electronic Vehicle Information
Center (EVIC) with instructions on how to complete
the requested shift. Refer to “Electronic Vehicle Infor-
mation Center (EVIC)” in “Understanding Your In-
strument Panel” for further information.

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

•When engaging Rear E-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 E-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 off.
• Shifting into or out of Rear E-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 E-Locker System must be disengaged prior to
taking the vehicle out of 4WD LOW range. If 4WD
LOW shift conditions/interlocks are not met, a mes-
sage will flash from the Electronic Vehicle Information
Center (EVIC) with instructions on how to complete
the requested shift.
SELEC-TERRAIN™
Description

control systems, along with driver input, to provide the
best performance for all terrains.
Rotate the Selec-Terrain™ knob to select the desired
mode.5
STARTING AND OPERATING 443

Avoid abrupt downshifts on icy or slippery roads be-
cause engine braking may cause skidding and loss of
control.
Hill Climbing
NOTE:Before attempting to climb a hill, determine the
conditions at the crest and/or on the other side.
Before climbing a steep hill, shift the transmission to a
lower gear and shift the 4WD System to 4WD LOW. Use
first gear and 4WD LOW for very steep hills.
If you stall or begin to lose headway while climbing a
steep hill, allow your vehicle to come to a stop and
immediately apply the brakes. Restart the engine and
shift to REVERSE. Back slowly down the hill allowing the
compression braking of the engine to help regulate your
speed. If the brakes are required to control vehicle speed,
apply them lightly and avoid locking or skidding the
tires.
WARNING!
If the engine stalls or you lose headway or cannot
make it to the top of a steep hill or grade, never
attempt to turn around. To do so may result in
tipping and rolling the vehicle. Always back straight
down a hill in REVERSE gear carefully. Never back
down a hill in NEUTRAL using only the brake.
Remember, never drive diagonally across a hill - drive
straight up or down.
If the wheels start to slip as you approach the crest of a
hill, ease off the accelerator and maintain headway by
turning the front wheels slowly left and right. This may
provide a fresh “bite” into the surface and will usually
provide traction to complete the climb.
