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.

ning. This is in violation of most coun-
tries regulations and may cause the
“Malfunction Indicator Light” to turn
on.
• A fire may result if fuel is pumped into a
portable container that is inside of a
vehicle. You could be burned. Always
place fuel containers on the ground
while filling.

Avoid Using Contaminated Fuel
Fuel that is contaminated by water or dirt can
cause severe damage to the engine fuel sys-
tem. Proper maintenance of the engine fuelfilter and fuel tank is essential. Refer to
“Dealer Service” in “Servicing And Mainte-
nance” in your Owner’s Manual for further
information.
Bulk Fuel Storage — Diesel Fuel
If you store quantities of fuel, good mainte-
nance of the stored fuel is also essential. Fuel
contaminated with water will promote the
growth of “microbes.” These microbes form
“slime” that will clog the fuel filtration sys-
tem and lines. Drain condensation from the
supply tank and change the line filter on a
regular basis.
NOTE:
When a diesel engine is allowed to run out of
fuel, air is pulled into the fuel system.
If the vehicle will not start, refer to “Dealer
Service / Priming If The Engine Has Run Out
Of Fuel” in “Servicing And Maintenance” in
your Owner’s Manual for further information.
WARNING!
Do not open the high pressure fuel system
with the engine running. Engine operation
WARNING!
causes high fuel pressure. High pressure
fuel spray can cause serious injury or
death.
Diesel Exhaust Fluid
Your vehicle is equipped with a Selective
Catalytic Reduction system to meet the very
stringent diesel emissions standards required
by the Environmental Protection Agency.
The purpose of the SCR system is to reduce
levels of NOx (oxides of nitrogen emitted from
engines) that are harmful to our health and
the environment to a near-zero level. A small
quantity of Diesel Exhaust Fluid (DEF) is
injected into the exhaust upstream of a cata-
lyst where, when vaporized, it converts smog-
forming nitrogen oxides (NOx) into harmless
nitrogen (N2) and water vapor (H2O), two
natural components of the air we breathe.
You can operate with the comfort that your
vehicle is contributing to a cleaner, healthier
world environment for this and generations to
come.

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.
