2015 JEEP CHEROKEE engine

FOUR-WHEEL DRIVE OPERATION
1–SPEED FOUR-WHEEL DRIVE (4X4)
• This feature provides on-demand
Four-Wheel Drive (4X4) with no driver
inputs or additional driving skills re-
quired.
• Under normal driving conditions, the
front wheels provide most of the trac-
tion.
• If the front wheels begin to lose trac-
tion, power is shifted automatically to
the rear wheels.
NOTE:
On dry pavement under heavy throttle in-
put (where one may have no wheel spin),
torque will be sent to the rear wheels to
improve vehicle launch and performance
characteristics.
2–SPEED FOUR-WHEEL DRIVE (4X4)
•This electronically shifted Power Trans-
fer Unit provides three mode positions:
• Four-wheel drive low range
(4X4 LOW)
• REAR LOCK
• NEUTRAL (N)
• The 4X4 LOW range can be used when
additional traction is required to force
the front and rear wheels to rotate at
the same speed.
• 4X4 LOW is intended for loose, slip-
pery road surfaces only.
NOTE:
In 4X4 LOW the engine speed is approxi-
mately 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).

REAR ELECTRONIC LOCKER (E-LOCKER) SYSTEM
• 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:
• The 4WD system must be in 4WD LOW.
• The ignition switch in the ON position or the engine running.
• Vehicle speed must be below 15 MPH (24 km/h).
• 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:
• Rear E-Locker must be engaged, and the REAR LOCK indicator light on.
• The ignition switch in the ON position or the engine running.
• 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.
• 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.
OFF-ROAD CAPABILITIES

• 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
4X4 LOW range. If 4X4 LOW shift conditions/interlocks are not met, a message will
flash from the Electronic Vehicle Information Center (EVIC)/Driver Information
Display with instructions on how to complete the requested shift.
SELEC-TERRAIN™
• Selec-Terrain™ combines the capa-
bilities of the vehicle control systems,
along with driver input, to provide the
best performance for all terrains.
Rotate the mode control knob to select
the following Selec-Terrain™ positions:
•Auto— Fully automatic full time four-
wheel drive operation can be used on
and off road. Balances traction with
seamless steering feel to provide im-
proved handling and acceleration over
two-wheel drive vehicles.
•Snow— Tuning set for additional sta-
bility in inclement weather. Use on and
off road on loose traction surfaces such
as snow. When in SNOW mode (depending on certain operating conditions), the
transmission may use second gear (rather than first gear) during launches, to
minimize wheel slippage.
•Sport— This mode alters the transmission's automatic shift schedule for sportier
driving. Upshift speeds are increased to make full use of available engine power.
•Sand/Mud— Off road calibration for use on low traction surfaces such as mud,
sand, or wet grass. Driveline is maximized for traction. Some binding may be felt
on less forgiving surfaces. The electronic brake controls are set to limit traction
control management of throttle and wheel spin.
•Rock— Off-road calibration only available in 4WD LOW range. Traction based
tuning with improved steer-ability for use on high traction off-road surfaces.
Activate the Hill Descent Control for steep downhill control. Use for low speed
obstacles such as large rocks, deep ruts, etc.
NOTE:
SPORT mode is not available when 4X4 LOW is selected.

Shifting Into NEUTRAL (N)
WARNING!
You or others could be injured or killed if you leave the vehicle unattended with the
power transfer unit in the NEUTRAL (N) position without first fully engaging the
parking brake. The NEUTRAL (N) position disengages both the front and rear
driveshafts from the powertrain and will allow the vehicle to roll, even if the
transmission is in PARK. The parking brake should always be applied when the
driver is not in the vehicle.
Use the following procedure to prepare your vehicle for recreational towing.
