Activation/Deactivation
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. If
your vehicle is equipped with an Automatic
Transmission, the vehicle brakes may be au-
tomatically applied and released when per-
forming a reverse parking maneuver if the
system detects a possible collision with an
obstacle.
ParkSense can be active only when the gear
selector is in REVERSE or DRIVE. If
ParkSense is enabled at one of these gear
selector positions, the system will remain
active until the vehicle speed is increased to
approximately 7 mph (11 km/h) or above. A
display warning will appear in the instrument
cluster display indicating the vehicle is aboveParkSense operating speed. The system will
become active again if the vehicle speed is
decreased to speeds less than approximately
6 mph (9 km/h).
Engagement/Disengagement
To disengage the system, push the ParkSense
switch, located on the switch panel below the
Uconnect display.
When the system passes from engaged to
disengaged and vice versa, it is always ac-
companied by a dedicated message in the
instrument cluster display.
System engaged:ParkSense switch LED off.
System disengaged:ParkSense switch LED on
constantly.
The ParkSense switch LED lights up also in
the case of a ParkSense system failure. If the
button is pushed with a system failure, the
ParkSense switch LED flashes for about five
seconds, then it stays on constantly.After the ParkSense has been disengaged, it
will stay in this condition until the following
engagement, even if the ignition device
passes from ON/RUN to OFF and then again
to ON/RUN.Operation With A Trailer
The operation of the sensors is automatically
deactivated when the trailer's electric plug is
inserted in the vehicle's tow hook socket. The
sensors are automatically reactivated when
the trailer's cable plug is removed.
General Warnings
If “PARKSENSE UNAVAILABLE WIPE REAR
SENSORS" or "PARKSENSE UNAVAILABLE
WIPE FRONT SENSORS” appears in the in-
strument cluster display, 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 ACTIVE PARK
ASSIST SYSTEM — IF
EQUIPPED
The ParkSense Active Park Assist system is
intended to assist the driver during parallel
and perpendicular parking maneuvers by
identifying a proper parking space, providing
audible/visual instructions, and controlling
the steering wheel. The ParkSense Active
Park Assist system is defined as “semi-
automatic” since the driver maintains control
of the accelerator, gear selector and brakes.
Depending on the driver's parking maneuver
selection, the ParkSense Active Park Assist
system is capable of maneuvering a vehicle
into a parallel or a perpendicular parking
space on either side (i.e., driver side or pas-
senger side).
NOTE:
• The driver is always responsible for control-
ling the vehicle, responsible for any sur-
rounding objects, and must intervene as
required.• The system is provided to assist the driver
and not to substitute the driver.
• During a semi-automatic maneuver, if the
driver touches the steering wheel after be-
ing instructed to remove their hands from
the steering wheel, the system will cancel,
and the driver will be required to manually
complete the parking maneuver.
• The system may not work in all conditions
(e.g. environmental conditions such as
heavy rain, snow, etc., or if searching for a
parking space that has surfaces that will
absorb the ultrasonic sensor waves).
• New vehicles from the dealership must
have at least 30 miles (48 km) accumu-
lated before the ParkSense Active Park
Assist system is fully calibrated and per-
forms accurately. This is due to the sys-
tem’s dynamic vehicle calibration to im-
prove the performance of the feature. The
system will also continuously perform the
dynamic vehicle calibration to account for
differences such as over or under inflated
tires and new tires.Enabling And Disabling The ParkSense Active
Park Assist System
The ParkSense Active Park Assist system can
be enabled and disabled with the ParkSense
Active Park Assist switch, located on the
switch panel below the Uconnect display.
To enable the ParkSense Active Park Assist
system, push the ParkSense Active Park As-
sist switch once (LED turns on).
To disable the ParkSense Active Park Assist
system, push the ParkSense Active Park As-
sist switch again (LED turns off).

When the ParkSense Active Park Assist sys-
tem is enabled the “Active ParkSense
Searching - Push OK to Switch to Perpen-
dicular” message will appear in the instru-
ment cluster display. You may switch to per-
pendicular parking if you desire. Push the OK
button on the left side steering wheel switch
to change your parking space setting. You
may switch back to parallel parking if you
desire.
When searching for a parking space, use the
turn signal indicator to select which side of
the vehicle you want to perform the parking
maneuver.
NOTE:
If the turn signal is not activated, the
ParkSense Active Park Assist system will au-
tomatically search for a parking space on the
passenger's side of the vehicle.
Refer to your Owner's Manual for further
information.LANESENSE
LaneSense Operation
The LaneSense system is operational at
speeds above 37 mph (60 km/h) and below
112 mph (180 km/h). The LaneSense system
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 unintentionally drifts out of the
lane (no turn signal applied), the LaneSense
system provides a haptic warning in the form
of torque applied to the steering wheel to
prompt the driver to remain within the lane
boundaries. If the driver continues to unin-
tentionally drift out of the lane, the Lane-
Sense system provides a visual warning
through 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 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 visual and haptic
warnings through the instrument cluster dis-
play 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
provides an audible 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
LED in LaneSense button will be illuminated
while the system is deactivated.
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 “Lane-
Sense On” message is shown in the instru-
ment 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.

Back-Up Camera image will be displayed on
the Uconnect Display, located on the center
stack of the instrument panel.
If the Uconnect Display appears foggy, clean
the camera lens located on the rear of the
vehicle above the rear license plate.
Rear Camera — Viewing At Speed
When the vehicle is in PARK, NEUTRAL or
DRIVE, the Rear View Camera can be acti-
vated with the “Rear View Camera” button in
the Controls menu. This feature allows the
customer to monitor the area directly behind
the vehicle (or trailer, if equipped) for up toten seconds while at speed. If the vehicle
speed remains below 8 mph (13 km/h), the
Rear View Camera image will be displayed
continuously until deactivated via the “X”
button on the touchscreen.
Refer to “ParkView Rear Back-Up Camera” in
“Starting And Operating” in your Owner's
Manual for further details.
WARNING!
Drivers must be careful when backing up;
even when using the ParkView Rear
Back-Up Camera. Always check carefully
behind your vehicle, and be sure to check
for pedestrians, animals, other vehicles,
obstructions, or blind spots before backing
up. You must continue to pay attention
while backing up. Failure to do so can
result in serious injury or death.
STARTING AND OPERATING

System Overview
This vehicle is equipped with a Diesel Ex-
haust 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 emissions
requirements; while maintaining outstanding
fuel economy, drivability, torque and power
ratings.Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for
system messages and warnings.
NOTE:
• Your vehicle is equipped with a DEF injec-
tion system. You may occasionally hear an
audible clicking noise from under the ve-
hicle at a stop. This is normal operation.
• 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 tem-
peratures. 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 con-
tact 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.
STARTING AND OPERATING
182

Adding Diesel Exhaust Fluid
The DEF gauge (located on the instrument
cluster display) will display the level of DEF
remaining in the tank. Refer to “Instrument
Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
NOTE:
Driving conditions (altitude, vehicle speed,
load, etc.) will effect the amount of DEF that
is used in your vehicle.
DEF Fill Procedure
NOTE:
Refer to “Fluids And Lubricants” in the
“Technical Specifications” section for the
correct fluid type.
1. Remove cap from DEF fill inlet (located in
fuel door).
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 immedi-
ately update after a refill if the tempera-
ture of the DEF fluid is below 12F
(-11C). The DEF line heater will possi-
bly 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.

Checking Oil Level — Gasoline Engine
To assure proper lubrication of your vehicle’s
engine, the engine oil must be maintained at
the correct level. Check the oil level at regular
intervals, such as every fuel stop. The best
time to check the engine oil level is about five
minutes after a fully warmed up engine is
shut off.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil
level readings. Always maintain the oil level
within the SAFE zone on the dipstick. Adding
one quart of oil when the reading is at the
bottom of the SAFE zone will result in a
reading at the top of the safe zone on these
engines.
CAUTION!
Overfilling or underfilling the crankcase
will cause aeration or loss of oil pressure.
This could damage your engine.
Checking Oil Level — 3.0 Diesel Engine
To assure proper lubrication of your vehicle's
engine, the engine oil must be maintained at
the correct level. Check the oil level at regular
intervals. The best time to check the oil level
is before starting the engine after it has been
parked overnight. When checking oil after
operating the engine, first ensure the engine
is at full operating temperature, then wait for
five minutes after engine shutdown to check
the oil.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil
level readings. Add oil only when the level on
the dipstick is below the “MIN” mark. The
total capacity from the MIN mark to the MAX
mark is 1 qt (1 L).
CAUTION!
Overfilling or underfilling the crankcase
will cause oil aeration or loss of oil pres-
sure. This could damage your engine.NOTE:
It is possible for your oil level to be slightly
higher than a previous check. This would be
due to diesel fuel that may temporarily be in
the crankcase due to operation of the diesel
particulate filter regeneration strategy. This
fuel will evaporate out under normal opera-
tion.
Never operate the engine with oil level below
the “MIN” mark or above the upper “MAX”
mark.
Adding Washer Fluid
The instrument cluster display will indicate
when the washer fluid level is low. When the
sensor detects a low fluid level, the wind-
shield will light on the vehicle graphic outline
and the “WASHER FLUID LOW” message
will be displayed.
The fluid reservoir for the windshield washers
and the rear window washer is shared. The
fluid reservoir is located in the engine com-
partment, be sure to check the fluid level at
regular intervals. Fill the reservoir with wind-
shield washer solvent only (not radiator anti-
freeze). When refilling the washer fluid reser-
