STARTING AND OPERATING163
CLEANING THE PARKSENSE SYSTEM
Clean the Rear Park Assist 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.
PARKSENSE SYSTEM USAGE
P
RECAUTIONS
NOTE:
 Ensure that the rear fascia/bumper is 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 off, the instrument 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.
 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 the fascia/bumper, or it could provide
a false indication that an obstacle is behind the fascia/
bumper. 
Use the ParkSense switch to turn the ParkSense
system off if objects such as bicycle carriers, trailer
hitches, etc. are placed within 12 inches (30 cm) of 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.
PARKVIEW REAR BACK UP CAMERA
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.
Manual Activation Of The Rear View Camera

1. Press the Controls button located on the bottom of
the Uconnect display.

2. Press the Back Up Camera button to turn the Rear View Camera system on.
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 respon -
sible for safety and must continue to pay attention 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 be
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 vehicle 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.
 The vehicle must be driven slowly when using Park -
Sense 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 Park -
Sense.

Fuel Filler Door

WARNING!

Never have any smoking materials lit in or near the
vehicle when the fuel door is open or the tank is being
filled.
 Never add fuel when the engine is running. This is in
violation of most state and federal fire regulations and
may cause the Malfunction Indicator Light to turn on.
 A fire may result if fuel is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place fuel containers on the ground
while filling.

CAUTION!
Damage to the fuel system or emission control
system could result from using an improper fuel filler
cap. A poorly fitting cap could let impurities into the
fuel system. Also, a poorly fitting aftermarket cap can
cause the Malfunction Indicator Light (MIL) to illumi -
nate, due to fuel vapors escaping from the system.
 To avoid fuel spillage and overfilling, do not “top off”
the fuel tank after filling.
CAUTION!

168STARTING AND OPERATING
System Overview
This vehicle is equipped with a Diesel Exhaust Fluid (DEF)
injection system and a Selective Catalytic Reduction (SCR)
catalyst to meet the emission requirements.
The DEF injection system consists of the following
components:
DEF tank
 DEF pump
 DEF injector
 Electronically-heated DEF Lines
 NOx sensors
 Temperature sensors
 SCR catalyst
The DEF injection system and SCR catalyst enable the
achievement of diesel emission requirements; while
maintaining outstanding fuel economy, drivability, torque
and power ratings.
For system messages and warnings see
Úpage 108.
NOTE:
 Your vehicle is equipped with a DEF injection system.
You may occasionally hear an audible clicking noise
from under the vehicle at a stop. This is normal opera -
tion.
 The DEF pump will run for a period of time after engine
shutdown to purge the DEF system. This is normal
operation and may be audible from the rear of the
vehicle.
Diesel Exhaust Fluid Storage
Diesel Exhaust Fluid (DEF) is considered a very stable
product with a long shelf life. If DEF is kept in
temperatures between 10° and 90°F (-12° and 32°C), it
will last a minimum of one year.
DEF is subject to freezing at the lowest temperatures. For
example, DEF 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 DEF, it is important to know that:
Any containers or parts that come into contact with DEF
must be DEF compatible (plastic or stainless steel).
Copper, brass, aluminum, iron or non-stainless steel
should be avoided as they are subject to corrosion by
DEF.
 If DEF is spilled, it should be wiped up completely.
Adding Diesel Exhaust Fluid
The DEF gauge (located on the instrument cluster display)
will display the level of DEF remaining in the tank
Úpage 108.
NOTE:Driving conditions (altitude, vehicle speed, load, etc.) will
affect the amount of DEF that is used in your vehicle.
DEF FILL PROCEDURE
NOTE:
For the correct DEF fluid type see Úpage 374.

1. Remove cap from DEF fill inlet (located in fuel door).

Fuel and Diesel Exhaust Fluid Fill Location

2. Insert DEF fill adapter/nozzle into DEF fill inlet.
NOTE:
 The DEF gauge may take up to five seconds to
update after adding a gallon or more of Diesel
Exhaust Fluid (DEF) to the DEF tank. If you have a
fault related to the DEF system, the gauge may not
update to the new level. See an authorized dealer
for service.
 The DEF gauge may also not immediately update
after a refill if the temperature of the DEF fluid is
below 12°F (-11°C). The DEF tank heater will

2 — Diesel Exhaust Fluid Filler

23_JL_OM_EN_USC_t.book Page 168

STARTING AND OPERATING169
possibly warm up the DEF fluid and allow the
gauge to update after a period of run time. Under
very cold conditions, it is possible that the gauge
may not reflect the new fill level for several drives.
 Excessive overfilling of the DEF tank can result in
a MIL lamp/fault code and inaccurate level read -
ings.
Refilling With Nozzles
You can fill up at any DEF distributor.
Proceed as follows:
 Insert the DEF nozzle in the filler, start refilling and
stop refilling at the first shut-off (the shut-off indi -
cates that the DEF tank is full). Do not proceed
with the refilling, to prevent spillage of DEF.
 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 DEF tank.
 If systems which cannot be screwed in (e.g. tanks)
are used for refilling, after the indication appears
on the instrument panel display
Úpage 104 fill
the DEF tank with no more than 2 gal (8 L).
 If containers which can be screwed to the filler are
used, the reservoir is full when the DEF level in the
container stops pouring out. Do not proceed
further. 3. Stop filling the DEF tank immediately when any of the
following happen: DEF stops flowing from the fill
bottle into the DEF fill inlet, DEF splashes out the fill
inlet, or a DEF pump nozzle automatically shuts off.
4. Reinstall cap onto DEF fill inlet.
VEHICLE LOADING
CERTIFICATION LABEL
As required by National Highway Traffic Safety
Administration regulations, your vehicle has a certification
label affixed to the driver's side door or pillar.
This label contains the month and year of manufacture,
Gross Vehicle Weight Rating (GVWR), Gross Axle Weight
Rating (GAWR) front and rear, and Vehicle Identification
Number (VIN). A Month-Day-Hour (MDH) number is
included on this label and indicates the Month, Day and
Hour of manufacture. The bar code that appears on the
bottom of the label is your VIN.
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total permissible weight of your vehicle
including driver, passengers, vehicle, options and cargo.
The label also specifies maximum capacities of front and
rear axle systems (GAWR). Total load must be limited so
GVWR and front and rear GAWR are not exceeded.
CAUTION!
 To avoid DEF spillage, and possible damage to the
DEF tank from overfilling, do not “top off” the DEF
tank after filling.
 DO NOT OVERFILL. DEF will freeze below 12ºF
(-11ºC). The DEF system is designed to work in
temperatures below the DEF freezing point, however,
if the tank is overfilled and freezes, the system could
be damaged.
 When DEF is spilled, clean the area immediately with
water and use an absorbent material to soak up the
spills on the ground.
 Do not attempt to start your engine if DEF is acciden -
tally added to the diesel fuel tank as it can result in
severe damage to your engine, including but not
limited to failure of the fuel pump and injectors.
 Never add anything other than DEF to the tank –
especially any form of hydrocarbon such as diesel
fuel, fuel system additives, gasoline, or any other
petroleum-based product. Even a very small amount
of these, less than 100 parts per million or less than
1 oz. per 78 gal (295 L) will contaminate the entire
DEF system and will require replacement. If owners
use a container, funnel or nozzle when refilling the
tank, it should either be new or one that has only
been used for adding DEF. Mopar® provides an
attachable nozzle with its DEF for this purpose.
