2014 JEEP CHEROKEE clutch

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

•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 prop-
erly 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.
NEUTRAL Shift Procedure
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

WARNING! (Continued)
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.
1. Bring the vehicle to a complete stop and shift the transmission to PARK.
2. Turn OFF the ignition.
3. Turn the ignition switch to the ON/RUN position, but do not start the engine.
4. Press and hold the brake pedal.
5. Shift the transmission into NEUTRAL.
6. Using a ballpoint pen or similar object, press and hold the recessed power transfer unit NEUTRAL (N) button
(located above the selector switch) for four seconds.
440 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.

STARTING AND OPERATING 443

Safehold
Safehold is a safety feature of the Electric Park Brake
System that will engage the park brake automatically if
the vehicle is left unsecured while the ignition switch is
in RUN.
For automatic transmissions, the park brake will auto-
matically engage if all of the following conditions are
met:
•The vehicle is at a standstill
• There is no attempt to depress the brake pedal or
accelerator pedal
• The seat belt is unbuckled
• The driver door is open For manual transmissions, the park brake will automati-
cally engage if all of the following conditions are met:
•
The vehicle is at a standstill
• There is no attempt to depress the brake pedal or
accelerator pedal
• The clutch pedal is not pressed
• The seat belt is unbuckled
• The driver door is open
Safehold can be temporarily bypassed by pressing the
Electric Park Brake Switch while the driver door is open.
Once manually bypassed, Safehold will be enabled again
once the vehicle reaches 12 mph (20 km/h) or the ignition
is turned to the OFF position and back to ON again.
456 STARTING AND OPERATING

CAUTION!
•Racing the engine or spinning the wheels may lead
to transmission overheating and failure. Allow the
engine to idle with the transmission in NEUTRAL
for at least one minute after every five rocking-
motion cycles. This will minimize overheating and
reduce the risk of clutch or transmission failure
during prolonged efforts to free a stuck vehicle.
• When “rocking” a stuck vehicle by shifting be-
tween DRIVE/2nd gear and REVERSE, do not spin
the wheels faster than 15 mph (24 km/h), or drive-
train damage may result.
• Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure.
It can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no trans-
mission shifting occurring).
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause damage, or
even failure, of the axle and tires. A tire could
explode and injure someone. Do not spin your vehi-
cle’s wheels faster than 30 mph (48 km/h) or for
longer than 30 seconds continuously without stop-
ping when you are stuck and do not let anyone near
a spinning wheel, no matter what the speed.
RECOVERY STRAP — IF EQUIPPED
Your vehicle may be included with a recovery strap.
Recovery straps do not act like traditional tow straps,
chains, or winch cables.
