When you move the gear selector into
REVERSE with ParkSense turned off, the
instrument cluster display will show "Off" on
the vehicle graphic arcs 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 prop
-
erly. 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.
Ensure the ParkSense system is off if objects
such as bicycle carriers, trailer hitches, etc.,
are placed within 18 inches (45 cm) of the
rear fascia/bumper while driving the vehicle.
Failure to do so can result in the system
misinterpreting a close obstacle as a sensor
problem, causing the "Rear ParkSense
Unavailable Service Required" message to
appear in the instrument cluster display.
On vehicles equipped with a tailgate, Park -
Sense should be disabled when the tailgate
is in the lowered or open position and the
vehicle is in REVERSE. A lowered tailgate
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 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 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 indica -
tion 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.

2. Insert DEF fill adapter/nozzle into DEF tank filler neck.
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 autho -
rized 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 line 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.
Excessive overfilling of the DEF tank can
result in a MIL lamp/fault code and inac-
curate level readings. 3. Stop filling the DEF tank immediately when
any of the following happen: DEF stops
flowing from the fill bottle into the DEF tank,
DEF splashes out the filler neck, or a DEF
pump nozzle automatically shuts off.
4. Reinstall cap onto DEF tank.
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
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 over -
filled and freezes, the system could be
damaged.
When DEF is spilled, clean the area imme -
diately 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
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 Gallons (295 Liters) 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
is has only been used for adding DEF.
Mopar provides an attachable nozzle with
its DEF for this purpose.

STARTING AND OPERATING345
After Driving Off-Road
Off-road operation puts more stress on your
vehicle than does most on-road driving. After
going off-road, it is always a good idea to check
for damage. That way you can get any problems
taken care of right away and have your vehicle
ready when you need it.
Completely inspect the underbody of your
vehicle. Check tires, body structure, steering,
suspension, and exhaust system for damage.
Inspect the radiator for mud and debris and
clean as required.
Check threaded fasteners for looseness,
particularly on the chassis, drivetrain compo -
nents, steering, and suspension. Retighten
them, if required, and torque to the values
specified in the Service Manual.
Check for accumulations of plants or brush.
These things could be a fire hazard. They
might hide damage to fuel lines, brake hoses,
axle pinion seals, and propeller shafts.
After extended operation in mud, sand,
water, or similar dirty conditions, have the
radiator, fan, brake rotors, wheels, brake
linings, and axle yokes inspected and
cleaned as soon as possible.If you experience unusual vibration after
driving in mud, slush or similar conditions,
check the wheels for impacted material.
Impacted material can cause a wheel imbal-
ance and freeing the wheels of it will correct
the situation.
WARNING!
Abrasive material in any part of the brakes
may cause excessive wear or unpredictable
braking. You might not have full braking
power when you need it to prevent a collision.
If you have been operating your vehicle in
dirty conditions, get your brakes checked and
cleaned as necessary.

SOS Call System Limitations
Vehicles sold in Mexico DO NOT have SOS Call
system capabilities. SOS or other emergency line operators in
Mexico may not answer or respond to SOS
system calls.
If the SOS Call system detects a malfunction,
any of the following may occur at the time the
malfunction is detected, and at the beginning of
each ignition cycle:
The overhead console light located between
the ASSIST and SOS buttons will continuously
be illuminated red.
The Device Screen will display the following
message: “Vehicle device requires service.
Please contact an authorized dealer.”
An In-Vehicle Audio message will state
“Vehicle device requires service. Please
contact an authorized dealer.”
Even if the SOS Call system is fully functional,
factors beyond FCA US LLC’s control may
prevent or stop the SOS Call system operation.
These include, but are not limited to, the
following factors:Delayed accessories mode is active.
The ignition is in the OFF position.
The vehicle’s electrical systems are not
intact.
The SOS Call system software and/or hard
-
ware are damaged during a crash.
The vehicle battery loses power or becomes
disconnected during a vehicle crash.
The SOS Call system is embedded into the
vehicle’s electrical system. Do not add
aftermarket electrical equipment to the
vehicle’s electrical system. This may
prevent your vehicle from sending a signal
to initiate an emergency call. To avoid inter -
ference that can cause the SOS Call system
to fail, never add aftermarket equipment
(e.g., two-way mobile radio, CB radio, data
recorder, etc.) to your vehicle’s electrical
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 SOS 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.
