Service The ParkSense Park Assist System
During vehicle start up, when the ParkSense
System has detected a faulted condition, the
instrument cluster will actuate a single
chime, once per ignition cycle, and it will
display the “PARKSENSE UNAVAILABLE
WIPE REAR SENSORS”, “PARKSENSE
UNAVAILABLE WIPE FRONT SENSORS” or
“PARKSENSE UNAVAILABLE SERVICE
REQUIRED” message. When the gear
selector is moved to REVERSE and the
system has detected a faulted condition, the
instrument cluster display will display a car
graphic with an overlay saying “Wipe Off” or
“Service”. Under this condition, ParkSense
will not operate. Refer to “Instrument Cluster
Display” in “Getting To Know Your Instru-
ment Panel” for further information.
If “PARKSENSE UNAVAILABLE WIPE REAR
SENSORS” or “PARKSENSE UNAVAILABLE
WIPE FRONT SENSORS” appears in the
instrument cluster display make sure the
outer surface and the underside of the rear
fascia/bumper and/or front fascia/bumper is
clean and clear of snow, ice, mud, dirt or
other obstruction and then cycle the ignition.
If the message continues to appear, see an
authorized dealer. If the “PARKSENSE UNAVAILABLE
SERVICE REQUIRED” message appears in
the instrument cluster display, see an autho
-
rized dealer.
Cleaning The ParkSense System
Clean the ParkSense sensors with water, car
wash soap, and a soft cloth. Do not use rough
or hard cloths. In washing stations, clean
sensors quickly keeping the vapor jet/high
pressure washing nozzles at least 4 inches
(10 cm) from the sensors. Do not scratch or
poke the sensors. Otherwise, you could
damage the sensors.
ParkSense System Usage Precautions
NOTE:
Ensure that the front and rear bumpers are
free of snow, ice, mud, dirt and debris to
keep the ParkSense system operating
properly.
Jackhammers, large trucks, and other
vibrations could affect the performance of
ParkSense.
When you turn ParkSense System off, the
instrument cluster display will show the
“ParkSense Off” message for two seconds.
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 System
is turned off, the instrument cluster
display will show the “ParkSense Off”
message. This message will be displayed
for as long as the vehicle is in REVERSE.
NOTE:
The “ParkSense Off” message will not
display while the vehicle is in 4LO position.
ParkSense, when on, will reduce the
volume of the radio when it is sounding a
tone.
Clean the ParkSense sensors regularly,
taking 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 or in front of the
fascia/bumper, or it could provide a false
indication that an obstacle is behind or in
front of the fascia/bumper.
Use the ParkSense switch to turn the
ParkSense system off if obstacles such as
bicycle carriers, trailer hitches, etc. are
2020_JEEP_JL_WRANGLER_UG_RHD_UK.book Page 166

(Continued)
(Continued)
placed within 30 cm from the rear fascia/
bumper. Failure to do so can result in the
system misinterpreting a close obstacle as
a sensor problem, causing the “PARK
-
SENSE UNAVAILABLE SERVICE
REQUIRED” message to appear in the
instrument cluster display.
ParkSense should be disabled when the
swing gate is in the open position. An open
swing gate could provide a false indication
that an obstacle is behind the vehicle.
PARKVIEW REAR BACK UP
CAMERA — IF EQUIPPED
The ParkView Rear Back Up Camera allows
you to see an on-screen image of the rear
surroundings of your vehicle whenever the
gear selector is put into REVERSE. The
image will be displayed in the touchscreen
display along with a caution note to “check
entire surroundings” across the top of the
screen. After five seconds this note will
disappear. The ParkView camera is located
on the rear of the vehicle in the center of the
spare tire. 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 contin -
uous 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.
CAUTION!
ParkSense is only a parking aid and it is
unable to recognize every obstacle,
including small obstacles. Parking curbs
might be temporarily detected or not
detected at all. Obstacles located above
or below the sensors will not be detected
when they are in close proximity.
WARNING! (Continued)
The vehicle must be driven slowly when
using ParkSense in order to be able to
stop in time when an obstacle is
detected. It is recommended that the
driver looks over his/her shoulder when
using ParkSense.
CAUTION! (Continued)

builds up on the camera lens, clean the lens,
rinse with water, and dry with a soft cloth. Do
not cover the lens.
WARNING!
Drivers must be careful when backing up
even when using the ParkView Rear Back
Up Camera. Always check carefully behind
your vehicle, and be sure to check for
pedestrians, animals, other vehicles,
obstructions, or blind spots before backing
up. You are responsible for the safety of
your surroundings and must continue to
pay attention while backing up. Failure to
do so can result in serious injury or death.
CAUTION!
To avoid vehicle damage, ParkView
should only be used as a parking aid. The
ParkView camera is unable to view every
obstacle or object in your drive path.
To avoid vehicle damage, the vehicle

NOTE:
When the fuel nozzle “clicks” or shuts off,
the fuel tank is full.
Tighten the fuel filler cap about a quarter
turn until you hear one click. This is an
indication that the cap is properly tight-
ened.

If the fuel filler cap is not tightened properly,
the MIL will come on. Be sure the cap is
tightened every time the vehicle is refueled.

Loose Fuel Filler Cap Message
After fuel has been added, the vehicle diag -
nostic system can determine if the fuel filler
cap is possibly loose, improperly installed,
or damaged. If the system detects a
malfunction, the “gASCAP” message will
display in the odometer display. Tighten the
gas cap until a "clicking" sound is heard.
This is an indication that the gas cap is
properly tightened. Push the odometer reset
button to turn the message off. If the
problem persists, the message will appear
the next time the vehicle is started. This
might indicate a damaged cap. If the
problem is detected twice in a row, the
system will turn on the MIL. Resolving the
problem will turn the MIL off.
REFUELING THE VEHICLE —
DIESEL
The fuel filler cap is located on the
passenger's side of the vehicle. If the fuel

AdBlue® (UREA) Storage
AdBlue® (UREA) is considered a very stable
product with a long shelf life. If AdBlue®
(UREA) is kept in temperatures between 10°
and 90°F (-12° and 32°C), it will last a
minimum of one year.
AdBlue® (UREA) is subject to freezing at the
lowest temperatures. For example, AdBlue®
(UREA) may freeze at temperatures at or
below 12°F (-11°C). The system has been
designed to operate in this environment.
NOTE:
When working with AdBlue® (UREA), it is
important to know that:
Any containers or parts that come into
contact with AdBlue® (UREA) must be
AdBlue® (UREA) compatible (plastic or
stainless steel). Copper, brass, aluminum,
iron or non-stainless steel should be
avoided as they are subject to corrosion by
AdBlue® (UREA).
If AdBlue® (UREA) is spilled, it should be
wiped up completely.
Adding AdBlue® (UREA)
Preliminary Conditions
AdBlue® (UREA) freezes at temperatures
lower than 12°F (-11°C). If the car stands for
a long time at this temperature refilling
could be difficult. For this reason, it is
advised to park the vehicle in a garage and/
or heated environment and wait for the urea
to return to liquid state before topping up.
Proceed as follows:
Park the car on flat ground and stop the
engine by placing the ignition to the OFF
position.
Open the fuel door, undo and remove the
cap (blue) from the AdBlue® (UREA)
filler.
Refilling With Nozzles
You can fill up at any AdBlue® (UREA)
distributor.
Proceed as follows:
Insert the AdBlue® (UREA) nozzle in the
filler, start refilling and stop refilling at the
first shut-off (the shut-off indicates that the AdBlue® (UREA) tank is full). Do not
proceed with the refilling, to prevent
spillage of AdBlue® (UREA).
Extract the nozzle.
Refilling With Containers
Proceed as follows:
Check the expiration date.
Read the advice for use on the label before
pouring the content of the bottle into the
AdBlue® (UREA) tank.
If systems which cannot be screwed in
(e.g. tanks) are used for refilling, after the
indication appears on the instrument
panel display refer to “Warning lights And
Messages” in the “Getting To Know Your
Instrument Panel” for further information,
fill the AdBlue® (UREA) tank with no
more than 2 Gallons (8 liters).
If containers which can be screwed to the
filler are used, the reservoir is full when
the AdBlue® (UREA) level in the
container stops pouring out. Do not
proceed further.
2020_JEEP_JL_WRANGLER_UG_RHD_UK.book Page 172

173
Operations After Refilling
Proceed as follows:
Fit the cap back on the AdBlue® (UREA)
filler by turning it clockwise and screwing
it completely.
Place the ignition in RUN (it is not neces-
sary to start the engine).

Wait for the indication on the instrument
panel to switch off before moving the car.
The indication may stay on for a few seconds
to approximately half a minute. If the engine
is started and the car is moved, the indica-
tion will remain on for longer. This will not
compromise engine operation.

If the AdBlue® (UREA) was topped up
when the tank was empty, wait for
2 minutes before starting the engine.
NOTE:
If AdBlue® (UREA) is spilled out of the
filler neck, clean up well the area and
proceed to filling up again. If the liquid
crystallizes, eliminate it with a sponge and
warm water.
DO NOT EXCEED THE MAXIMUM LEVEL:
this could cause damage to the reservoir.
AdBlue® (UREA) freezes at under 12°F
(-11°C). Although the system is designed
to operate below the freezing point of the
AdBlue® (UREA), it is advisable not to fill
the tank beyond the maximum level
because if the AdBlue® (UREA) freezes
the system can be damaged. Follow the
instructions in this section.
If the AdBlue® (UREA) is spilled on
painted surfaces or aluminum, immedi -
ately clean the area with water and use
absorbent material to collect the fluid that
has been spilled on the ground.
Do not try to start the engine if AdBlue®
(UREA) was accidentally added to the
diesel fuel tank, this can result in serious
engine damage, contact an authorized
dealer.
Do not add additives or other fluids to
AdBlue® (UREA), doing so could damage
the system.
The use of non-conforming or degraded
AdBlue® (UREA) may lead to indications
appearing on the instrument panel display
refer to “Warning Lights And Messages” in
the “Getting To Know Your Instrument
Panel” for further information.
Never pour AdBlue® (UREA) into another
container: it could be contaminated.
If the AdBlue® (UREA) runs out, see refer
to “Warning Lights And Messages” in the
“Getting To Know Your Instrument Panel”
for further information to continue using
the car normally.
