2014 JEEP CHEROKEE engine

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

NOTE:Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur. If the transmission cannot be reset, authorized
dealer service is required.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear. For example, if
you shift the transmission into 5 (fifth gear), the trans-
mission will not shift above fifth gear, but will shift
through the lower gears normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the shift lever is in the DRIVE
position, the transmission will operate automatically,
shifting between all available gears. Moving the shift lever to the ERS position (beside
DRIVE) will activate ERS mode, display the current gear
in the instrument cluster, and maintain that gear as the
top available gear. Once in ERS mode, moving the shift
lever forward (-) or rearward (+) will change the top
available gear.
To exit ERS mode, simply return the shift lever to the
DRIVE position.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid, causing a collision or
personal injury.
434 STARTING AND OPERATING

NOTE:To select the proper gear position for maximum
deceleration (engine braking), simply press and hold the
shift lever forward (-). The transmission will shift to the
range from which the vehicle can best be slowed down.
FOUR-WHEEL DRIVE OPERATION
1-Speed Four-Wheel Drive (4WD) — If Equipped
This feature provides on-demand four-wheel drive
(4WD). The system is automatic with no driver inputs or
additional driving skills required. Under normal driving
conditions, the front wheels provide most of the traction.
If the front wheels begin to lose traction, power is shifted
automatically to the rear wheels. The greater the front
wheel traction loss, the greater the power transfer to the
rear wheels. Additionally, on dry pavement under heavy throttle
input (where one may have no wheel spin), torque will be
sent to the rear in a pre-emptive effort to improve vehicle
launch and performance characteristics.
1-Speed 4WD Switch

STARTING AND OPERATING 435

When additional traction is required, the 4WD LOW
range position can be used to provide an additional gear
reduction which allows for increased torque to be deliv-
ered to both the front and rear wheels. 4WD LOW is
intended for loose, slippery road surfaces only. Driving in
4WD LOW on dry, hard-surfaced roads may cause in-
creased tire wear and damage to driveline components.
When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the normal
driving mode at a given road speed. Take care not to
overspeed the engine and do not exceed 25 mph
(40 km/h).
Proper operation of four-wheel drive vehicles depends
on tires of equal size, type, and circumference on each
wheel. Any difference will adversely affect shifting and
cause damage to the driveline components.Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
Shift Positions
For additional information on the appropriate use of each
4WD system mode position, see the information below:
NEUTRAL
This range disengages the driveline from the powertrain.
It is to be used for flat towing behind another vehicle.
Refer to “Recreational Towing” in “Starting and Operat-
ing” for further information.5
STARTING AND OPERATING 437

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.

STARTING AND OPERATING 439

•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
