184STARTING AND OPERATING
When the condition that deactivated the system is
no longer present, the system will return to the
“Adaptive Cruise Control Off” state and will resume
function by simply reactivating it.
NOTE:
If the “ACC/FCW Unavailable Wipe Front Radar
Sensor” message occurs frequently (e.g. more
than once on every trip) without any snow, rain,
mud, or other obstruction, have the radar
sensor realigned at an authorized dealer.
Installing a snow plow, front-end protector, an
aftermarket grille or modifying the grille is not
recommended. Doing so may block the sensor
and inhibit ACC/FCW operation.
“CLEAN FRONT WINDSHIELD” WARNING
The “ACC/FCW Limited Functionality Clean Front
Windshield” warning will display and a chime will
sound when conditions temporarily limit system
performance. This most often occurs at times of
poor visibility, such as in snow or heavy rain and
fog. The ACC system may also become temporarily
blinded due to obstructions, such as mud, dirt, or
ice on windshield, driving directly into the sun and
fog on the inside of glass. In these cases, the
instrument cluster display will show “ACC/FCW
Limited Functionality Clean Front Windshield” and
the system will have degraded performance. This message can sometimes be displayed while
driving in adverse weather conditions. The ACC/
FCW system will recover after the vehicle has left
these areas. Under rare conditions, when the
camera is not tracking any vehicles or objects in its
path this warning may temporarily occur.
If weather conditions are not a factor, the driver
should examine the windshield and the camera
located on the back side of the inside rear view
mirror. They may require cleaning or removal of an
obstruction.
When the condition that created limited
functionality is no longer present, the system will
return to full functionality.
NOTE:If the “ACC/FCW Limited Functionality Clean Front
Windshield” message occurs frequently (e.g. more
than once on every trip) without any snow, rain,
mud, or other obstruction, have the windshield and
forward facing camera inspected at an authorized
dealer.
SERVICE ACC/FCW WARNING
If the system turns off, and the instrument cluster
displays “ACC/FCW Unavailable Service Required”
or “Cruise/FCW Unavailable Service Required”,
there may be an internal system fault or a
temporary malfunction that limits ACC
functionality. Although the vehicle is still drivable under normal conditions, ACC will be temporarily
unavailable. If this occurs, try activating ACC again
later, following an ignition cycle. If the problem
persists, see an authorized dealer.
Precautions While Driving With ACC
NOTE:
Aftermarket add-ons such as snow plows, lift
kits, and brush/grille bars can hinder module
performance. Ensure the radar/camera has no
obstructions in the field of view.
Height modifications can limit module perfor
-
mance and functionality.
Do not put stickers or easy passes over the
camera/radar field of view.
Any modifications to the vehicle that may
obstruct the field of view of the radar/camera
are not recommended.
In certain driving situations, ACC may have
detection issues. In these cases, ACC may brake
late or unexpectedly. The driver needs to stay alert
and may need to intervene. The following are
examples of these types of situations:

190STARTING AND OPERATING
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.
Adjustable Chime Volume Settings
The Front and Rear chime volume settings are
programmable through the Uconnect system
Ú page 234.
ENABLING AND DISABLING FRONT

instrument cluster display will show a vehicle
graphic with “OFF” on the corresponding side. This
vehicle graphic will be displayed for as long as the
vehicle is in REVERSE.
NOTE:Arc alerts from the enabled ParkSense system, will
interrupt the five second messages, and the
instrument cluster display will show the vehicle
graphic with the corresponding arcs and “OFF”
message.
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 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 the "PARKSENSE
UNAVAILABLE SERVICE REQUIRED" message for
five seconds. When the gear selector is moved to
REVERSE and the system has detected a faulted condition, the instrument cluster display will
display a "WIPE OFF" message on the
corresponding blocked system while the vehicle is
in REVERSE. The system will continue to provide
arc alerts for the side that is functioning properly.
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.
NOTE:Water from a car wash or road slush in freezing
weather may also cause sensors to become
blocked.
If the "PARKSENSE UNAVAILABLE SERVICE
REQUIRED" message appears in the instrument
cluster display, see your 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.

22_DT_OM_EN_USC_t.book Page 190

STARTING AND OPERATING191
PARKSENSE SYSTEM USAGE
P
RECAUTIONS
NOTE:
Ensure that the front and rear fascias/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 Park -
Sense.
When you turn Front or Rear ParkSense off, the
instrument cluster display will show a vehicle
graphic of the Front or Rear ParkSense on/off
state for two seconds. Furthermore, once you
turn Front or Rear 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 Front or Rear ParkSense
is turned off, the instrument cluster display will
show a vehicle graphic with "OFF" in the corre -
sponding side. 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 near the rear
fascia/bumper. Failure to do so can result in the
system misinterpreting a close obstacle as a
sensor problem, causing the “PARKSENSE
UNAVAILABLE SERVICE REQUIRED” message to
be appear in the instrument cluster display.
ParkSense should be disabled when the tailgate
is in the lowered or open position. A lowered tail -
gate could provide a false indication that an
obstacle is behind the vehicle and could also
cause a false braking event.
The Rear ParkSense system will automatically
disable when the system detects that a trailer
with trailer brakes has been connected to the
Integrated Trailer Brake Module.
The Front ParkSense system will automatically
disable if a snow plow has been connected to
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 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/bumper 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, and give a
false indication that an obstacle is behind the
vehicle, and could cause false braking.

Diesel Exhaust Fluid (DEF) Fill Procedure
NOTE:
For the correct fluid type Úpage 473.

1. Remove cap from Diesel Exhaust Fluid (DEF) tank which is located next to the diesel fuel
filler.

DEF Filler Cap And Fuel Fill
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
(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 condi -
tions, it is possible that the gauge may not
reflect the new fill level for several drives.
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 indicates 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 114 fill the DEF 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
DEF level in the container stops pouring out.
Do not proceed further.
1 — Diesel Exhaust Fluid (DEF) Fill Location
2 — Diesel Fuel Fill Location
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.

232STARTING AND OPERATING
OFF-ROAD DRIVING TIPS
Care should be taken when attempting to climb
steep hills or driving diagonally across a hill or
slope. If natural obstacles force you to travel
diagonally up or down a hill, choose a mild angle
and keep as little side tilt as possible. Keep the
vehicle moving and make turns slowly and
cautiously.
If you must back down a hill, back straight down
using REVERSE gear. Never back down in
NEUTRAL or diagonally across the hill.
When driving over sand, mud, and other soft
terrain, shift to low gear and drive steadily. Apply
the accelerator slowly to avoid spinning the
wheels.
Do not reduce the tire pressures for this type of
driving.
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, partic -
ularly on the chassis, drivetrain components,
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 mate -
rial can cause a wheel imbalance 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.
