4WD JEEP CHEROKEE 2016 KL / 5.G User Guide

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 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.
NOTE:
On dry pavement under heavy throttle
input (where one may have 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 Transfer Unit provides three mode positions:
• Four Wheel Drive High (4WD)
• Neutral (N)
• Four Wheel Drive Low (4WDLOW)
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, slippery
road surfaces only.

The NEUTRAL position allows vehicles with 2-speed Four-Wheel Drive to be flat
towed (with all wheels on the ground) without damaging the drivetrain. Refer to
“Recreational Towing” for instructions on shifting into and out of NEUTRAL.
NOTE:
In 4X4 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).
Shifting Procedures
4X4 HI To 4X4 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.
NOTE:
If shift conditions/interlocks are not met a message will flash from the Electronic
Vehicle Information Center (EVIC)/Driver Information Display (DID) with instructions
on how to complete the requested shift. Refer to “Electronic Vehicle Information
Center (EVIC)/Driver Information Display (DID)” in “Understanding Your Instrument
Panel” on the DVD for further information.
4X4 LOW To 4X4 HI
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.

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, push 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 , push the REAR LOCK button once.
NOTE:
• It may also be necessary to drive slowly steering back and forth to completeengagement 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.
• 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 capabilities 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 (de-
pending on certain operating condi-
tions), the transmission may use sec-
ond 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.

Recreational Towing — 4X4 Models With 2-Speed Power Transfer Unit
The power transfer unit must be shifted into NEUTRAL (N) and the transmission
must be in PARK for recreational towing. The NEUTRAL (N) selection button is
adjacent to the 4WD selector switch. Shifts into and out of NEUTRAL (N) can take
place with the selector switch in any mode position.
CAUTION!
• DO NOT dolly tow any 4x4 vehicle. Towing with only one set of wheels on theground (front or rear) will cause severe transmission and/or power transfer unit
damage. Tow with all four wheels either ON the ground, or OFF the ground
(using a vehicle trailer).
• Tow only in a forward direction. Towing this vehicle backwards can cause severe
damage to the power transfer unit.
• The transmission must be in PARK for recreational towing.
• Before recreational towing, perform the procedure outlined under “Shifting
into NEUTRAL (N)” to be certain that the power transfer unit is fully in
NEUTRAL (N). Otherwise, internal damage will result.
• Towing this vehicle in violation of the above requirements can cause severe
transmission and/or power transfer unit damage. Damage from improper
towing is not covered under the New Vehicle Limited Warranty.
• Ensure that the Electric Park Brake is released, and remains released, while
being towed.
• Do not use a bumper-mounted clamp-on tow bar on your vehicle. The bumper
face bar will be damaged.
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
automatic transmission is in PARK (or manual transmission is in gear). 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.
CAUTION!
It is necessary to follow these steps to be certain that the power transfer unit is fully
in NEUTRAL (N) before recreational towing to prevent damage to internal parts.

- Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of an onboard diagnostic system called
OBD II that monitors engine and automatic transmission control systems. The light
will illuminate when the key is in the ON/RUN position before engine start. If the bulb
does not come on when turning the key from OFF to ON/RUN, have the condition
checked promptly.
Certain conditions, poor fuel quality, etc., may illuminate the light after engine start.
The vehicle should be serviced if the light stays on through several of your typical
driving cycles. In most situations, the vehicle will drive normally and will not require
towing.
CAUTION!
Prolonged driving with the Malfunction Indicator Light (MIL) on could cause
damage to the engine control system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic converter damage and power
loss will soon occur. Immediate service is required.
WARNING!
A malfunctioning catalytic converter, as referenced above, can reach higher
temperatures than in normal operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such as dry plants, wood,
cardboard, etc. This could result in death or serious injury to the driver, occupants
or others.
– SERV (Service) 4WD Indicator Light
If the light stays on or comes on during driving, it means that the 4WD system is not
functioning properly and that service is required. We recommend you drive to the
nearest service center and have the vehicle serviced immediately.
- Electronic Stability Control (ESC) Activation/Malfunction Indicator Light
If this indicator light flashes during acceleration, apply as little throttle as possible.
While driving, ease up on the accelerator. Adapt your speed and driving to the
prevailing road conditions. To improve the vehicle's traction when starting off in deep
snow, sand or gravel, it may be desirable to switch the ESC system off.
