2018 JEEP CHEROKEE service

WARNING!
• When entering a turn lane or highway offramp; when driving on roads that are
winding, icy, snow-covered, slippery, or
have steep uphill or downhill slopes.
• When towing a trailer up or down steep
slopes.
• When circumstances do not allow safe
driving at a constant speed.
The Cruise Control system has two control
modes:
•
Adaptive Cruise Control mode for main-
taining an appropriate distance between
vehicles.
• Normal (Fixed Speed) Cruise Control
mode for cruising at a constant preset
speed. For additional information, refer
to “Normal (Fixed Speed) Cruise Control
Mode” in your Owner’s Manual for fur-
ther information.
Normal (Fixed Speed) Cruise Control will not
react to preceding vehicles. Always be aware
of the mode selected. You can change the
mode by using the Cruise Control buttons.
The two control modes function differently.
Always confirm which mode is selected.
PARKSENSE REAR PARK
ASSIST
ParkSense Sensors
The four ParkSense sensors, located in the
rear fascia/bumper, monitor the area behind
the vehicle that is within the sensors’ field of
view. The sensors can detect obstacles from
approximately 12 inches (30 cm) up to
79 inches (200 cm) from the rear fascia/
bumper in the horizontal direction, depend-
ing on the location, type and orientation of
the obstacle.
Enabling And Disabling ParkSense
ParkSense can be enabled and disabled with
the ParkSense switch, located on the switch
panel below the Uconnect display.
When the ParkSense switch is pushed to
disable the system, the instrument cluster
display will show the “PARKSENSE OFF”
message for approximately five seconds. Re-
fer to “Instrument Cluster Display” in “Get-
ting To Know Your Instrument Panel” in your Owner’s Manual for further information.
When the gear selector is moved to REVERSE
and the system is disabled, the instrument
cluster display will show the “PARKSENSE
OFF” message for as long as the vehicle is in
REVERSE.
The ParkSense switch LED will be on when
ParkSense is disabled or requires service.
The ParkSense switch LED will be off when
the system is enabled. If the ParkSense
switch is pushed, and requires service, the
ParkSense switch LED will blink momen-
tarily, and then the LED will be on.
Instrument Cluster Display — Warning
The ParkSense Warning screen will only be
displayed if Sound and Display is selected
from the Customer - Programmable Features
section of the Uconnect System. Refer to
"Uconnect Settings” in “Multimedia” in your
Owner's Manual for further information.
147

The ParkSense Warning screen is located
within the instrument cluster display. It pro-
vides visual warnings to indicate the distance
between the rear fascia/bumper and the de-
tected obstacle. Refer to “Instrument Cluster
Display” in your Owner's Manual for further
information.
ParkSense System Usage Precautions
• Ensure that the rear bumper is free of snow,ice, mud, dirt and debris to keep the
ParkSense system operating properly.
• Jackhammers, large trucks, and other vi- brations could affect the performance of
ParkSense.
• When you turn ParkSense off, the instru- ment cluster display will read
“PARKSENSE OFF”. Furthermore, once
you turn ParkSense off, it remains off until
you turn it on again, even if you cycle the
ignition.
• When you move the gear selector to the REVERSE position and ParkSense is
turned off, the instrument cluster display
will show a “PARKSENSE OFF” message
for as long as the vehicle is in REVERSE. • ParkSense, when on, will reduce the vol-
ume of the radio when it is sounding a tone.
• Clean the ParkSense sensors regularly, tak- ing care not to scratch or damage them.
The sensors must not be covered with ice,
snow, slush, mud, dirt or debris. Failure to
do so can result in the system not working
properly. The ParkSense system might not
detect an obstacle behind the fascia/
bumper, or it could provide a false indica-
tion that an obstacle is behind the fascia/
bumper.
• Use the ParkSense switch to turn the ParkSense system OFF if objects such as
bicycle carriers, etc. are placed within
12 inches (30 cm) from the rear fascia/
bumper. Failure to do so can result in the
system misinterpreting a close object as a
sensor problem, causing the “PARKSENSE
UNAVAILABLE SERVICE REQUIRED”
message to be displayed in the instrument
cluster display.
• ParkSense should be disabled when the liftgate is in the open position and the
vehicle is in REVERSE. An open liftgate
could provide a false indication that an
obstacle is behind the vehicle.
WARNING!
• Drivers must be careful when backing up
even when using ParkSense. Always
check carefully behind your vehicle,
look behind you, and be sure to check
for pedestrians, animals, other vehicles,
obstructions, and blind spots before
backing up. You are responsible for
safety and must continue to pay atten-
tion to your surroundings. Failure to do
so can result in serious injury or death.
• Before using ParkSense, it is strongly
recommended that the ball mount and
hitch ball assembly is disconnected
from the vehicle when the vehicle is not
used for towing. Failure to do so can
result in injury or damage to vehicles or
obstacles because the hitch ball will be
much closer to the obstacle than the
rear fascia when the loudspeaker sounds
the continuous tone. Also, the sensors
could detect the ball mount and hitch
ball assembly, depending on its size and
shape, giving a false indication that an
obstacle is behind the vehicle.

5 seconds, then it stays on constantly.
After the ParkSense has been disengaged, it
will stay in this condition until the following
engagement, even if the ignition device
passes from ON/RUN to OFF and then again
to ON/RUN.
Operation With A Trailer
The operation of the sensors is automatically
deactivated when the trailer's electric plug is
inserted in the vehicle's tow hook socket. The
sensors are automatically reactivated when
the trailer's cable plug is removed.
General Warnings
If “PARKSENSE UNAVAILABLE WIPE REAR
SENSORS" or "PARKSENSE UNAVAILABLE
WIPE FRONT SENSORS” appears in the in-
strument cluster display, clean the

Bi-Xenon High Intensity Discharge (HID)
Headlamps — If Equipped
The headlamps contain a type of high voltage
discharge light source. High voltage can re-
main in the circuit even with the headlamp
switch off. Because of this, you should not
attempt to service a HID headlamp light source yourself. If an HID headlamp light
source fails, take your vehicle to an autho-
rized dealer for service.
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.
WARNING!
A transient high voltage occurs at the bulb
sockets of HID headlamps when the head-
lamp switch is turned ON. It may cause
serious electrical shock or electrocution if
not serviced properly. See your authorized
dealer for service.

FUSES
WARNING!
• When replacing a blown fuse, always usean appropriate replacement fuse with
the same amp rating as the original fuse.
Never replace a fuse with another fuse of
higher amp rating. Never replace a
blown fuse with metal wires or any other
material. Do not place a fuse inside a
circuit breaker cavity or vice versa. Fail-
ure to use proper fuses may result in
serious personal injury, fire and/or prop-
erty damage.
• Before replacing a fuse, make sure that
the ignition is off and that all the other
services are switched off and/or disen-
gaged.
• If the replaced fuse blows again, contact
an authorized dealer.
WARNING!
• If a general protection fuse for safetysystems (air bag system, braking sys-
tem), power unit systems (engine sys-
tem, transmission system) or steering
system blows, contact an authorized
dealer.
General Information
The fuses protect electrical systems against
excessive current.
When a device does not work, you must check
the fuse element inside the blade fuse for a
break/melt.
Also, please be aware that when using power
outlets for extended periods of time with the
engine off may result in vehicle battery dis-
charge.
Underhood Fuses
The Power Distribution Center is located in
the engine compartment near the battery.
This center contains cartridge fuses, mini-
fuses and relays. A label that identifies each
component is printed on the inside of the
cover.

JACKING AND TIRE
CHANGING
WARNING!
• Do not attempt to change a tire on theside of the vehicle close to moving traf-
fic. Pull far enough off the road to avoid
the danger of being hit when operating
the jack or changing the wheel.
• Being under a jacked-up vehicle is dan-
gerous. The vehicle could slip off the
jack and fall on you. You could be
crushed. Never put any part of your body
under a vehicle that is on a jack. If you
need to get under a raised vehicle, take
it to a service center where it can be
raised on a lift.
• Never start or run the engine while the
vehicle is on a jack.
• The jack is designed to be used as a tool
for changing tires only. The jack should
not be used to lift the vehicle for service
purposes. The vehicle should be jacked
on a firm level surface only. Avoid ice or
slippery areas.
Jack Location/Spare Tire Stowage
The jack, wheel chocks and spare tire are
stowed under the load floor behind the rear
seat.
1. Open the liftgate.
2. Lift the access cover using the load floor handle. 3. Remove the hook from the stowed posi-
tion on the back side of the load floor and
place the hook over the top body flange
and weather seal. This will hold the load
floor up while obtaining the jack and spare
tire.
4. Remove the fastener securing the jack and spare tire.
5. Remove the chocks.
6. Remove the scissors jack and wheel bolt wrench from the spare wheel as an assem-
bly. Turn the jack screw to the left to
loosen the wheel bolt wrench, and remove
the wrench from the jack assembly.
NOTE:
The jack handle attaches to the side of the
jack with two attachment points. When
the jack is partially expanded, the tension
between the two attachment points holds
the jack handle in place.
7. Remove the spare tire.

WARNING!
A loose tire or jack thrown forward in a
collision or hard stop could endanger the
occupants of the vehicle. Always stow the
jack parts and the spare tire in the places
provided. Have the deflated (flat) tire re-
paired or replaced immediately.
Preparations For Jacking
1. Park the vehicle on a firm level surface asfar from the edge of the roadway as pos-
sible. Avoid icy or slippery areas.
WARNING!
Do not attempt to change a tire on the side
of the vehicle close to moving traffic. Pull
far enough off the road to avoid being hit
when operating the jack or changing the
wheel.
2. Turn on the Hazard Warning flasher.
3. Apply the parking brake.
4. Place the gear selector into PARK (auto- matic transmission) or REVERSE (manual
transmission). 5. Turn the ignition off to the LOCK position.
6. Chock both the front and rear of the wheel
diagonally opposite of the jacking posi-
tion. For example, if changing the right
front tire, chock the left rear wheel.
NOTE:
Passengers should not remain in the vehicle
when the vehicle is being jacked.
