object, the chime rate will change from single
1/2 second tone (for rear only), to slow (for
rear only), to fast, to continuous.
Enabling And Disabling ParkSense
ParkSense can be enabled and disabled with
the ParkSense switch.
When the ParkSense switch is
pushed to disable the system, the
instrument cluster will display the
“PARKSENSE OFF” message for
approximately five seconds. When the gear
selector is moved to REVERSE and the sys-
tem is disabled, the instrument cluster dis-
play will display the “PARKSENSE OFF”
message for as long as the vehicle is in
REVERSE.
Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” in
your Owner’s Manual for further information.
NOTE:
When ParkSense is disabled and the gear
selector is moved to the DRIVE position, no
warning message will be displayed.The ParkSense switch LED will be on when
ParkSense is disabled or requires service.
The ParkSense switch LED will be off when
the system is enabled. If the ParkSense
switch is pushed, and the system requires
service, the ParkSense switch LED will blink
momentarily, and then the LED will be on.
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.
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 controlof 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).

quantity AdBlue (UREA) is injected into the
exhaust upstream of a catalyst 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 AdBlue
(UREA) injection system and a Selective
Catalytic Reduction (SCR) catalyst to meet
the emission requirements.
The AdBlue (UREA) injection system con-
sists of the following components:
• AdBlue (UREA) Tank
• AdBlue (UREA) Pump
• AdBlue (UREA) Injector
• Electronically-heated AdBlue (UREA)
Lines
• NOx sensors• Temperature sensors
• SCR catalyst
The AdBlue (UREA) injection system and
SCR catalyst enable the achievement of die-
sel emissions requirements; while maintain-
ing 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 AdBlue
(UREA) injection system. You may occa-
sionally hear an audible clicking noise from
under the vehicle at a stop. This is normal
operation.
• The AdBlue (UREA) pump will run for a
period of time after engine shutdown to
purge the AdBlue (UREA) system. This is
normal operation and may be audible from
the rear of the vehicle.
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 con-
tact 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.

Example: If garage temperature = 68°F
(20°C) and the outside temperature = 32°F
(0°C) then the cold tire inflation pressure
should be increased by 3 psi (21 kPa), which
equals 1 psi (7 kPa) for every 12°F (7°C) for
this outside temperature condition.
Tire pressure may increase from 2 to 6 psi
(13 to 40 kPa) during operation. DO NOT
reduce this normal pressure build up or your
tire pressure will be too low.
Tire Pressures For High Speed Operation
The manufacturer advocates driving at safe
speeds and within posted speed limits.
Where speed limits or conditions are such
that the vehicle can be driven at high speeds,
maintaining correct tire inflation pressure is
very important. Increased tire pressure and
reduced vehicle loading may be required for
high-speed vehicle operation. Refer to an
authorized tire dealer or original equipment
vehicle dealer for recommended safe operat-
ing speeds, loading and cold tire inflation
pressures.
WARNING!
High speed driving with your vehicle under
maximum load is dangerous. The added
strain on your tires could cause them to
fail. You could have a serious collision. Do
not drive a vehicle loaded to the maximum
capacity at continuous speeds above
75 mph (120 km/h).
Radial Ply Tires
WARNING!
Combining radial ply tires with other types
of tires on your vehicle will cause your
vehicle to handle poorly. The instability
could cause a collision. Always use radial
ply tires in sets of four. Never combine
them with other types of tires.
Tire Repair
If your tire becomes damaged, it may be
repaired if it meets the following criteria:
• The tire has not been driven on when flat.
•
The damage is only on the tread section of
your tire (sidewall damage is not repairable).
• The puncture is no greater thana¼ofan
inch (6 mm).
Consult an authorized tire dealer for tire re-
pairs and additional information.
Damaged Run Flat tires, or Run Flat tires that
have experienced a loss of pressure should be
replaced immediately with another Run Flat
tire of identical size and service description
(Load Index and Speed Symbol). Replace the
tire pressure sensor as well as it is not de-
signed to be reused.
Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive
50 miles (80 km) at 50 mph (80 km/h) after
a rapid loss of inflation pressure. This rapid
loss of inflation is referred to as the Run Flat
mode. A Run Flat mode occurs when the tire
inflation pressure is of/or below 14 psi
(96 kPa). Once a Run Flat tire reaches the
run flat mode it has limited driving capabili-
ties and needs to be replaced immediately. A
Run Flat tire is not repairable. When a run flat
tire is changed after driving with underin-
241

flated tire condition, please replace the TPM
sensor as it is not designed to be reused when
driven under run flat mode (14 psi (96 kPa))
condition.
NOTE:
TPM Sensor must be replaced after driving
the vehicle on a flat tire condition.
It is not recommended driving a vehicle
loaded at full capacity or to tow a trailer while
a tire is in the run flat mode.
See the tire pressure monitoring section for
more information.
Tire Spinning
When stuck in mud, sand, snow, or ice con-
ditions, do not spin your vehicle's wheels
above 30 mph (48 km/h) or for longer than
30 seconds continuously without stopping.
Refer to “Freeing A Stuck Vehicle” in “In
Case Of Emergency” for further information.
WARNING!
Fast spinning tires can be dangerous.
Forces generated by excessive wheel
WARNING!
speeds may cause tire damage or failure. A
tire could explode and injure someone. Do
not spin your vehicle's wheels faster than
30 mph (48 km/h) for more than 30 sec-
onds continuously when you are stuck,
and do not let anyone near a spinning
wheel, no matter what the speed.
Tread Wear Indicators
Tread wear indicators are in the original
equipment tires to help you in determining
when your tires should be replaced.These indicators are molded into the bottom
of the tread grooves. They will appear as
bands when the tread depth becomes a
1/16 of an inch (1.6 mm). When the tread is
worn to the tread wear indicators, the tire
should be replaced.
Refer to “Replacement Tires” in this section
for further information.
Life Of Tire
The service life of a tire is dependent upon
varying factors including, but not limited to:
• Driving style.
• Tire pressure - Improper cold tire inflation
pressures can cause uneven wear patterns
to develop across the tire tread. These ab-
normal wear patterns will reduce tread life,
resulting in the need for earlier tire replace-
ment.
• Distance driven.
• Performance tires, tires with a speed rating
of V or higher, and Summer tires typically
have a reduced tread life. Rotation of these
tires per the vehicle scheduled mainte-
nance is highly recommended.
