light JEEP CHEROKEE TRAILHAWK 2018 Owner's Manual

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.
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, slip-
pery road surfaces only. Do not exceed 25 mph (40 km/h).
NOTE:Refer to “Selec-Terrain — If Equipped” for further
information on the various positions and their intended
usages.
Shifting Procedures
Shifting Into 4X4 LOW
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the
ignition in the ON mode and the engine running, shift the
transmission into NEUTRAL, and push 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 mes-
sage will flash from the instrument cluster display with
instructions on how to complete the requested shift. Refer
to “Instrument Cluster Display” in “Getting To know Your
Instrument Panel” for further information.
Shifting Out Of 4X4 LOW
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the
ignition in the ON mode and the engine running, shift the
transmission into NEUTRAL, and push 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 instrument cluster display with instruc-
tions on how to complete the requested shift. Refer to
“Instrument Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
• 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 properly
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

NOTE:
•Rock mode is only available on the vehicles equipped
with the Off-Road package.
• Activate the Hill Descent Control or Selec Speed Control
for steep downhill control. See “Electronic Brake Control
System” in “Safety” for further information.
Instrument Cluster Display Messages
When the appropriate conditions exist, a message will
appear in the instrument cluster. Refer to “Instrument
Cluster Display” in “Getting To Know Your Instrument
Panel” for further information.
POWER STEERING
The electric power steering system will give you good
vehicle response and increased ease of maneuverability in
tight spaces. The system will vary its assist to provide light
efforts while parking and good feel while driving. If the
electric steering system experiences a fault that reduces
assist or prevents the vehicle from providing assist, you
will still have the ability to steer the vehicle manually.

STARTING AND OPERATING 265

2. Open the fuel filler door, and remove the fuel filler cap.
NOTE:
•In certain cold conditions, ice may prevent the fuel door
from opening. If this occurs, lightly push on the fuel
door to break the ice buildup and re-release the fuel door
using the inside release button. Do not pry on the door.
• When the fuel nozzle “clicks” or shuts off, the fuel tank
is full.
• Tighten the gas cap about one quarter turn until you
hear one click. This is an indication that the cap is
properly tightened. •
If the gas cap is not tightened properly, the Malfunction
Indicator Light (MIL) will come on. Be sure the gas cap
is tightened every time the vehicle is refueled.

(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.
Driving In Snow, Mud And Sand
In heavy snow, when pulling a load, or for additional
control at slower speeds, shift the transmission to a low
gear and shift the 4WD system to the appropriate terrain
mode, using 4WD LOW if necessary. Refer to “Four-Wheel
Drive Operation” in “Starting And Operating” for further
information. Do not shift to a lower gear than necessary to
maintain headway. Over-revving the engine can spin the
wheels and traction will be lost.
Avoid abrupt downshifts on icy or slippery roads because
engine braking may cause skidding and loss of control.
Hill Climbing
NOTE:Before attempting to climb a hill, determine the
conditions at the crest and/or on the other side.
Before climbing a steep hill, shift the transmission to a
lower gear and shift the 4WD System to 4WD LOW. Use
first gear and 4WD LOW for very steep hills.
NOTE: Brakes should be applied at increased slippage, but
before coming to a stop to avoid digging into the loose
surface and rendering the operator of the vehicle stuck/
immobile.
If you stall or begin to lose headway while climbing a
steep hill, allow your vehicle to come to a stop and
immediately apply the brakes. Once stopped, shift to
REVERSE. Back slowly down the hill allowing the com-
pression braking of the engine to help regulate your speed.
If the brakes are required to control vehicle speed, apply
them lightly and avoid locking or skidding the tires.

WARNING!(Continued)
can cause the 9-1-1 Call system to fail, never add
aftermarket equipment (e.g., two-way mobile radio,
CB radio, data recorder, etc.) to your vehicle’s electri-
cal system or modify the antennas on your vehicle.
IF YOUR VEHICLE LOSES BATTERY POWER FOR
ANY REASON (INCLUDING DURING OR AFTER
AN ACCIDENT), THE UCONNECT FEATURES,
APPS AND SERVICES, AMONG OTHERS, WILL
NOT OPERATE.
• Modifications to any part of the 9-1-1 Call system
could cause the air bag system to fail when you need
it. You could be injured if the air bag system is not
there to help protect you.
9-1-1 Call System Limitations
Vehicles sold in Canada and Mexico DO NOThave 9-1-1
Call system capabilities.
9-1-1 or other emergency line operators in Canada and
Mexico may not answer or respond to 9-1-1 system calls.
If the 9-1-1 Call system detects a malfunction, any of the
following may occur at the time the malfunction is de-
tected, and at the beginning of each ignition cycle: •
The Rearview Mirror light located between the ASSIST
and 9-1-1 buttons will continuously be illuminated red.
• The Device Screen will display the following message
“Vehicle device requires service. Please contact your
dealer.”
• An In-Vehicle Audio message will state “Vehicle device
requires service. Please contact your dealer.”

NOTE:On vehicles equipped with HID headlamps, when
the headlamps are turned on, there is a blue hue to the
lights. This diminishes and becomes more white after
approximately 10 seconds, as the system charges.

NOTE:•For vehicles so equipped, do not attempt to install a
center cap or wheel cover on the compact spare.
• Refer to “Compact Spare Tire” and to “Limited-Use
Spare” under “Tires—General Information” in “Servic-
ing And Maintenance” for additional warnings, cau-
tions, and information about the spare tire, its use, and
operation.
9. Install the wheel bolts with the threaded end of the wheel bolt toward the wheel. Lightly tighten the wheel
bolts.

Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact with
oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressures. The manu-
facturer strongly recommends that you use tires equivalent
to the originals in size, quality and performance when
replacement is needed. Refer to the paragraph on “Tread
Wear Indicators” in this section. Refer to the Tire and
Loading Information placard or the Vehicle Certification
Label for the size designation of your tire. The Load Index
and Speed Symbol for your tire will be found on the
original equipment tire sidewall.
See the Tire Sizing Chart example found in the “Tire Safety
Information” section of this manual for more information
relating to the Load Index and Speed Symbol of a tire.
It is recommended to replace the two front tires or two rear
tires as a pair. Replacing just one tire can seriously affect
your vehicle’s handling. If you ever replace a wheel, make
sure that the wheel’s specifications match those of the
original wheels.It is recommended you contact an authorized tire dealer or
original equipment dealer with any questions you may
have on tire specifications or capability. Failure to use
equivalent replacement tires may adversely affect the
safety, handling, and ride of your vehicle.

WARNING!
The temperature grade for this tire is established for
a tire that is properly inflated and not overloaded.
Excessive speed, under-inflation, or excessive load-
ing, either separately or in combination, can cause
heat buildup and possible tire failure.
STORING THE VEHICLE
If the vehicle should remain stationary for more than a
month, observe the following precautions:
• Park your vehicle in a covered, dry and possibly airy
location the windows open slightly.
• Check that the Electric Park Brake is not engaged.
• Disconnect the negative (-) terminal from the battery
post and be sure that the battery is fully charged. During
storage check battery charge quarterly.
• If you do not disconnect the battery from the electrical
system, check the battery charge every 30 days.
• Clean and protect the painted parts by applying protec-
tive waxes. •
Clean and protect polished metal parts by applying
protective waxes.
• Apply talcum powder to the front and rear wiper blades
and leave raised from the glass.
• Cover the vehicle with an appropriate cover taking care
not to damage the painted surface by dragging across
dirty surfaces. Do not use plastic sheeting which will not
allow the evaporation of moisture present on the surface
of the vehicle.
• Inflate the tires at a pressure of +7.25 psi (+0.5 bar)
higher than recommended on the tire placard and check
it periodically.
• Do not drain the engine cooling system.
• Whenever you leave the vehicle is stationary for two
weeks or more, run idle the engine for approximately
five minutes, with the air conditioning system on and
high fan speed. This will ensure a proper lubrication of
the system, thus minimizing the possibility of damage to
the compressor when the vehicle is put back into opera-
tion.
