PARKSENSE FRONT AND
REAR PARK ASSIST — IF
EQUIPPED
The ParkSense Park Assist system provides
visual and audible indications of the
distance between the rear and/or front fascia
and a detected obstacle when backing up or
moving forward (e.g. during a parking
maneuver). The vehicle brakes may be auto-
matically applied and released when
performing a reverse parking maneuver if the
system detects a possible collision with an
obstacle.
Refer to “ParkSense System Usage Precau -
tions” in “Starting And Operating” in the
Owner’s Manual for limitations of this system
and recommendations.
ParkSense will retain the last system state
(enabled or disabled) from the last ignition
cycle when the ignition is changed to the ON/
RUN position.
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.
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.

will also operate in this manner when only a
single lane marking is detected and the driver
unintentionally drifts across the lane marking
(no turn signal applied).

The driver may manually override the haptic
warning by applying torque into the steering
wheel at any time.
When only a single lane marking is detected
and the driver unintentionally drifts across
the lane marking (no turn signal applied), the
LaneSense system provides a haptic 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.
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 when the driver’s hands are not
detected on the steering wheel. The system
will cancel if the driver does not return their
hands to the wheel.Turning LaneSense On Or Off
The default status of LaneSense is “off”.
The LaneSense button is located on the
switch panel below the Uconnect 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 once (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. Base Instrument Cluster Display — If Equipped
When the LaneSense system is on, the lane
lines are gray when both of the lane bound
-
aries have not been detected and the Lane -
Sense telltale is solid white.
Left Lane Departure — Only Left Lane Detected
When the LaneSense system senses a lane
drift situation, the left thick lane line and
left thin lane line turn solid white. The
LaneSense telltale changes from solid
green to solid yellow. At this time, torque
is applied to the steering wheel in the
opposite direction of the lane boundary.
For example: If approaching the left side
of the lane, the steering wheel will turn
right.
When the LaneSense system senses the
lane has been approached and is in a lane
departure situation, the LaneSense
system will show a solid white left line, a
solid gray right line, and a solid yellow tell-
tale.
NOTE:
The LaneSense system operates with the
similar behavior for a right lane departure
when only the right lane marking has been
detected.

Adblue® (UREA) — If Equipped
The vehicle is equipped with an UREA injec-
tion system and Selective Catalytic Reduc -
tion to meet emission standards. These two
systems ensure compliance with the diesel
emissions requirements; at the same time,
they ensure fuel-efficiency, handling, torque
and power. For messages and system warn -
ings, refer to the “Warning Lights And
Messages” in the “Getting To Know Your
Instrument Panel” section. AdBlue® (UREA)
is a very stable product with a long shelf life.
Stored at temperatures LOWER than 90 °F
(32 °C), it has a shelf life of at least one year.
For more information on the AdBlue® liquid
type, see the “Fluids and lubricants” in the
“Technical specifications” section. The
vehicle is equipped with an automatic
AdBlue® heating system when the engine
starts allowing the system to work correctly
at temperatures lower than 12 °F (-11 °C).
NOTE:
AdBlue® freezes at temperatures lower than
12 °F (-11 °C).
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 in the OFF
position.
Open the fuel door, undo and remove the
cap (blue) from the AdBlue® (UREA)

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 1.6 Gallons (6 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.
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 to RUN (it is not neces-
sary to start the engine).
