NOTE:ParkSense will reduce the volume of the radio, if
on, when the system is sounding an audio tone.
ParkSense Camera Activation
If the ParkSense system detects an obstacle, a
camera image will display in the radio. The camera
will continue to display as long as the ParkSense
system continues to detect an object. This can be
turned on or off in the Uconnect system
Úpage 199.
Front Park Assist Audible Alerts
ParkSense will turn off the Front Park Assist
audible alert (chime) after approximately three
seconds when an obstacle has been detected, the
vehicle is stationary, and brake pedal is applied.

The Front and Rear chime volume settings are
programmable through the Uconnect system
Ú page 199.
ENABLING AND DISABLING PARKSENSE
Front ParkSense can be enabled and
disabled with the Front ParkSense
switch.
Rear ParkSense can be enabled and disabled with
the Rear ParkSense switch.
When the gear selector is moved to REVERSE and
the Front or Rear system is disabled, the instrument cluster display will show a vehicle
graphic with an “Off” message overlay over the
system that is off (Front or Rear system). This
vehicle graphic will be displayed for as long as the
vehicle is in REVERSE.
The Front or Rear ParkSense switch LED will be on
when Front or Rear ParkSense is disabled or
requires service. The Front or Rear ParkSense
switch LED will be off when the Front or Rear
system is enabled. If the Front or Rear ParkSense
switch is pushed, and the system requires service,
the Front or Rear ParkSense switch LED will blink
momentarily, and then the LED will be on.
SERVICE THE PARKSENSE PARK ASSIST
S
YSTEM
During vehicle start-up, when the Front/Rear
ParkSense System has detected a faulted
condition, the instrument cluster display will show
the "Front/Rear ParkSense Unavailable Service
Required" or the "Front/Rear ParkSense
Unavailable Wipe Sensors" message.
When the gear selector is moved into REVERSE, a
vehicle graphic will show in the instrument cluster
display, along with the display overlay “Wipe
Sensors.” If the system needs service, the display
overlay will read “Service.” Under this condition,
ParkSense will not operate. If "Front/Rear ParkSense Unavailable Wipe
Sensors" appears in the instrument cluster display
make sure the outer surface and the underside of
the rear 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 "Front/Rear ParkSense Unavailable Service
Required" appears in the instrument cluster
display, see an authorized 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. Do not scratch or poke the sensors.
Otherwise, you could damage the sensors.
PARKSENSE SYSTEM USAGE
P
RECAUTIONS
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 vibra -
tions could affect the performance of
ParkSense.

23_DPF_OM_EN_USC_t.book Page 162

STARTING AND OPERATING163
When you move the gear selector to the
REVERSE position and Front or Rear ParkSense
is turned off, the instrument cluster display will
show "Off" on the vehicle graphic arcs. This
vehicle graphic will be displayed for as long as
the vehicle is in REVERSE.
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 placed within 18 inches
(45 cm) of the rear fascia/bumper. Failure to do
so can result in the system misinterpreting a
close obstacle as a sensor problem, causing the
“Front/Rear ParkSense Unavailable Service
Required” message to appear in the instrument
cluster display.
LANESENSE — IF EQUIPPED
LANESENSE OPERATION
The LaneSense system is operational at speeds
above 37 mph (60 km/h) and below 112 mph
(180 km/h). It uses a forward looking camera to
detect lane markings and measure vehicle
position within the lane boundaries.
When both lane markings are detected and the
driver drifts out of the lane (no turn signal has been
applied) OR the driver departs the lane on the
opposite side of the applied turn signal (if the left
turn signal is applied and the vehicle departs to the
right), the LaneSense system provides a haptic
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 attention to your
surroundings. Failure to do so can result in
serious injury or death.
Before using ParkSense, it is strongly recom -
mended 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
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.
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
ParkSense in order to be able to stop in time
when an obstacle is detected. It is recom -
mended that the driver looks over his/her
shoulder when using ParkSense.4

warning in the form of torque applied to the
steering wheel, as well as a visual warning in the
instrument cluster display to prompt the driver to
remain within the lane boundaries.
The driver may manually override the haptic
warning by applying torque to the steering wheel at
any time.
When only a single lane marking is detected and
the driver drifts across that lane marking (no turn
signal applied), the LaneSense system provides a
visual warning through the instrument cluster
display to prompt the driver to remain within the
lane.
When only a single lane marking is detected, a
haptic (torque) warning will not be provided.
NOTE:When operating conditions have been met, the
LaneSense system will monitor if the driver’s
hands are on the steering wheel and provide an
audible and visual warning to the driver if removed.
The system will cancel if the driver does not return
their hands to the wheel.
TURNING LANESENSE ON OR OFF
The LaneSense button is located on the
switch panel below the Uconnect display.
NOTE:If your vehicle is equipped with a 12–inch
Uconnect Display screen, the LaneSense button is
located above the display.
To turn the LaneSense system on, push the
LaneSense button (LED turns off). A “LaneSense
On” message is shown in the instrument cluster
display.
To turn the LaneSense system off, push the
LaneSense button again (LED turns on).
NOTE:The LaneSense system will retain the last system
state (on or off) from the last ignition cycle when
the ignition is changed to the ON/RUN position.
LANESENSE WARNING MESSAGE
The LaneSense system will indicate the current
lane drift condition through the instrument cluster
display.
When the LaneSense system is on, the lane lines
are gray when both of the lane boundaries have
not been detected and the LaneSense telltale
is solid white.
System ON (Gray Lines) With White Telltale

Left Lane Departure — Only Left Lane Detected
When the LaneSense system is on, the
LaneSense Telltale is solid white when only
the left lane marking has been detected and the
system is ready to provide visual warnings in the
instrument cluster display if an unintentional
lane departure occurs on the left side.
When the LaneSense system senses the lane
has been approached and is in a lane departure
situation, the visual warning in the instrument
cluster display will show the left lane line
flashing yellow (on/off). The LaneSense telltale
changes from solid white to flashing yellow.

STARTING AND OPERATING177
REFUELING THE VEHICLE— GASOLINE
ENGINE
If the fuel filler cap is lost or damaged, be sure the
replacement cap is the correct one for this vehicle.

1. Remove the fuel cap by rotating it counter -
clockwise.

2. Insert the refueling nozzle into the filler pipe.
3. Fill the vehicle with fuel.
NOTE:
When the fuel nozzle “clicks” or shuts off,
the fuel tank is full.
Wait five seconds before removing the fuel
nozzle to allow excess fuel to drain from the
nozzle.
4. Remove the refueling nozzle, reinstall the fuel cap.
NOTE:Tighten the gas cap a 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 will come on. Be sure
the gas cap is tightened every time the vehicle is
refueled.
LOOSE FUEL FILLER CAP MESSAGE
If the vehicle diagnostic system determines that
the fuel filler cap is loose, improperly installed, or
damaged, a loose gASCAP indicator will display in
the instrument cluster telltale display area
Ú
page 89. Tighten the fuel filler cap properly and
push the RIGHT button to turn off the message. If
the problem continues, the message will appear
the next time the vehicle is started.
REFUELING THE VEHICLE — DIESEL ENGINE
If the fuel filler cap is lost or damaged, be sure the
replacement cap is the correct one for this vehicle.

1. Remove the fuel cap by rotating it counter -
clockwise.

2. Insert the refueling nozzle into the filler pipe.
3. Fill the vehicle with fuel.
The inlet for the engine air intake is located
behind the passenger side headlamp and
receives air through the grille.
WARNING!WARNING!
Never have any smoking materials lit in or
near the vehicle when the gas cap is removed
or the tank is being filled.
Never add fuel to the vehicle when the engine
is running. This is in violation of most state
and federal fire regulations and may cause
the MIL to turn on.
CAUTION!
Damage to the fuel system or emissions
control system could result from using an
improper fuel tank filler tube cap (fuel filler
cap). A poorly fitting cap could let impurities
into the fuel system. Also, a poorly-fitted after
-
market cap can cause the Malfunction Indi -
cator Light (MIL) to illuminate due to fuel
vapors escaping from the system.
A poorly fitting fuel filler cap may cause the
MIL to turn on.
To avoid fuel spillage and overfilling, do not
“top off” the fuel tank after filling.
WARNING!
A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on
the ground while filling.

STARTING AND OPERATING179
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 (DEF)
The DEF gauge (located on the instrument cluster)
will display the level of DEF remaining in the tank
Úpage 89.
NOTE:
Driving conditions (altitude, vehicle speed, load,
etc.) will effect the amount of DEF that is used in
your vehicle.
Another factor is that outside temperature can
affect DEF consumption. In cold conditions,
12°F (-11°C) and below, the DEF gauge needle
can stay on a fixed position and may not move
for extended periods of time. This is a normal
function of the system.
There is an electric heater inside the DEF tank
that automatically works when necessary. If the
DEF supply does freeze, the truck will operate
normally until it thaws.
DEF FILL PROCEDURE
NOTE:
For the correct fluid type Ú page 419.
Remove cap from DEF tank (located on drivers side
of the vehicle or in fuel door).

DEF Filler Cap And Fuel Fill Chassis Cab Models

NOTE:
The DEF gauge may take up to five seconds to
update after adding a gallon or more of 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 39°F (4°C). The DEF tank
heater will 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.
At 40°F (4°C) you could see some increase in
the DEF gauge due to the tank thawing. The
gauge and level sensor are working properly and
are just updating with proper thawed DEF.
Excessive overfilling of the DEF tank can result
in a MIL lamp/fault code and inaccurate level
readings.
Refilling With Nozzles
You can fill up at any DEF distributor.
Proceed as follows:
Insert the DEF nozzle in the filler tube, start
refilling and stop refilling at the first shut-off (the
shut-off indicates that the DEF tank is full). DO
NOT proceed with the refilling, to prevent
spillage of DEF.
Extract the nozzle.

(Continued)
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.

After the indication appears on the instrument
cluster display
Úpage 89 fill the DEF tank with
no more than 6 gal (22 L).
Stop filling the DEF tank immediately if DEF
splashes or wells back in the filler neck.
Reinstall cap onto DEF filler tube.
Filling The Def Tank In Cold Climates
Since DEF will begin to freeze at 12°F (-11°C),
your vehicle is equipped with an automatic DEF
heating system. This allows the DEF injection
system to operate properly at temperatures below
12°F (-11°C). If your vehicle is not in operation for
an extended period of time with temperatures
below 12°F (-11°C), the DEF in the tank may
freeze. If the tank is overfilled and freezes, it could
be damaged. Therefore, do not overfill the DEF
tank. Extra care should be taken when filling with
portable containers to avoid overfilling. Note the
level of the DEF gauge in your instrument cluster.
You may safely add a maximum of 2 gal (7.5 L) of
DEF from portable containers when your DEF
gauge is reading ½ full.VEHICLE LOADING
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.
PAYLOAD
The payload of a vehicle is defined as the allowable
load weight a truck can carry, including the weight
of the driver, all passengers, options and cargo.
GROSS AXLE WEIGHT RATING (GAWR)
The GAWR is the maximum permissible load on the
front and rear axles. The load must be distributed
in the cargo area so that the GAWR of each axle is
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 immedi -
ately with water and use an absorbent mate -
rial to soak up the spills on the ground.
Do not attempt to start your engine if DEF is
accidentally 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 replace -
ment. 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.
