2017 JEEP CHEROKEE transfer unit

CAUTION!(Continued)
•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 disen-
gages 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 shift the 4WD system into
NEUTRAL (N).
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.
1. Bring the vehicle to a complete stop and shift the transmission to PARK.
2. Turn the engine OFF.
3. Turn the ignition to the ON/RUN mode, 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, push and hold the recessed NEUTRAL (N) button (located by the
selector switch) for four seconds. The light behind the N
symbol will blink, indicating shift in progress. The light
will stop blinking (stay on solid) when the shift to
NEUTRAL (N) is complete.
382 STARTING AND OPERATING

•The ignition must be in the ON/RUN mode for a shift to
take place and for the position indicator lights to be
operable. If the ignition is not in the ON/RUN mode, the
shift will not take place and no position indicator lights
will be on or flashing.
• A flashing NEUTRAL (N) position indicator light indi-
cates that shift requirements have not been met.
Shifting Out Of NEUTRAL (N)
Use the following procedure to prepare your vehicle for
normal usage.
1. Bring the vehicle to a complete stop, leaving it con- nected to the tow vehicle.
2. Apply the parking brake.
3. Turn the ignition to the ON/RUN mode, 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, push and hold the recessed power transfer unit NEUTRAL (N) button
(located by the selector switch) for one second. 7. When the NEUTRAL (N) indicator light turns off,
release the NEUTRAL (N) button.
8. After the NEUTRAL (N) button has been released, the power transfer unit will shift to the position indicated
by the selector switch.
NOTE: When shifting the power transfer unit out of
NEUTRAL (N), the engine should remain OFF to avoid
gear clash.
9. Shift the transmission into PARK.

Off-Road Driving Tips
Driving Through Water
Although your vehicle is capable of driving through water,
there are a number of precautions that must be considered
before entering the water:
NOTE:When driving through water, do not exceed 5 mph
(8 km/h). Always check water depth before entering as a
precaution, and check all fluids afterward. Driving through
water may cause damage that may not be covered by the
New Vehicle Limited Warranty.
Driving through water more than a few inches/centimeters
deep will require extra caution to ensure safety and pre-
vent damage to your vehicle. If you must drive through
water, try to determine the depth and the bottom condition
(and location of any obstacles) prior to entering. Proceed
with caution and maintain a steady controlled speed less
than 5 mph (8 km/h) in deep water to minimize wave
effects.
Flowing Water
If the water is swift flowing and rising (as in storm run-off)
avoid crossing until the water level recedes and/or the
flow rate is reduced. If you must cross flowing-water,
avoid depths in excess of 9 inches (22 cm). The flowing water can erode the streambed causing your vehicle to sink
into deeper water. Determine exit point(s) that are down-
stream of your entry point to allow for drifting.
Standing Water
Avoid driving in standing water deeper than 16 inches
(40.5 cm), and reduce speed appropriately to minimize
wave effects. Maximum speed in 16 inches (40.5 cm) of
water is less than 5 mph (8 km/h).
(Trailhawk only): Avoid driving in standing water deeper
than 19 inches (48 cm), and reduce speed appropriately to
minimize wave effects. Maximum speed in 19 inches (48
cm) of water is less than 5 mph (8 km/h).
Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine, transmission, Power Transfer
Unit and Rear Drive Module) to assure they have not been
contaminated. Contaminated fluids and lubricants (milky,
foamy in appearance) should be flushed/changed as soon
as possible to prevent component damage.

Front-Wheel Drive (FWD) Models
The manufacturer recommends towing your vehicle with
all four wheelsOFFthe ground using a flatbed.
If flatbed equipment is not available, this vehicle must
towed with the front wheels OFF the ground (using a
towing dolly, or wheel lift equipment with the front wheels
raised).
Ensure that the Electric Park Brake is released, and remains
released, while being towed.
CAUTION!
Towing this vehicle in violation of the above require-
ments can cause severe transmission damage. Damage
from improper towing is not covered under the New
Vehicle Limited Warranty.
4x4 Models With 1–Speed Power Transfer Unit
The manufacturer requires towing with all four wheels
OFF the ground.
Acceptable methods are to tow the vehicle on a flatbed, or
with one end of vehicle raised and the opposite end on a
towing dolly.
CAUTION!
• DO NOT tow this vehicle with ANY of its wheels on
the ground. Damage to the drivetrain will result.
•
Front or rear wheel lifts must not be used. Internal
damage to the transmission or power transfer unit will
occur if a front or rear wheel lift is used when towing.
•Towing this vehicle in violation of the above require-
ments can cause severe transmission and/or power
transfer unit damage. Damage from improper towing is
not covered under the New Vehicle Limited Warranty.
