• 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 the fascia/
bumper, or it could provide a false indica-
tion that an obstacle is behind the fascia/
bumper.
• Use the ParkSense switch to turn the ParkSense system OFF if objects such as
bicycle carriers, trailer hitches, etc. are
placed within 12 in (30 cm) from the rear
fascia/bumper. Failure to do so can result
in the system misinterpreting a close ob-
ject as a sensor problem, causing the
“PARKSENSE UNAVAILABLE SERVICE
REQUIRED” message to appear in the
instrument cluster display.
• ParkSense should be disabled when the liftgate is in the open position and the
vehicle is in REVERSE. An open liftgate
could provide a false indication that an
obstacle is behind the vehicle.WARNING!
• Drivers must be careful when backing upeven 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 continuous 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 isunable to recognize every obstacle, in-
cluding 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 de-
tected. It is recommended that the
driver looks over his/her shoulder when
using ParkSense.
PARKSENSE FRONT AND
REAR PARK ASSIST
Sensors
The four ParkSense sensors, located in the
rear fascia/bumper, monitor the area behind
the vehicle that is within the sensors field of
view. The sensors can detect obstacles from
approximately 12 inches (30 cm) up to

WARNING!
• Never have any smoking materials lit inor near the vehicle when the fuel door is
open or the tank is being filled.
• Never add fuel when the engine is run-
ning. This is in violation of most state
and federal fire 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.
CAUTION!
To avoid fuel spillage and overfilling, do
not “top off” the fuel tank after 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 fuel filter and fuel tank is essential. Refer to
“Dealer Service” in “Servicing And Mainte-
nance” 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” for
further information.
WARNING!
Do not open the high pressure fuel system
with the engine running. Engine operation
causes high fuel pressure. High pressure
WARNING!
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 re-
quired 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. Small
quantities 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.

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 infuel 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 your autho-
rized 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.
CAUTION!
•To avoid DEF spillage, and possible dam-
age to the DEF tank from overfilling, do
not “top off” the DEF tank after filling.
• DO NOT OVERFILL. DEF will freeze be- low 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.
• When DEF is spilled, clean the area immediately with water and use an ab-
sorbent material to soak up the spills on
the ground.
• Do not attempt to start your engine if DEF is accidentally added to the diesel
fuel tank as it can result in severe dam-
age to your engine, including but not
limited to failure of the fuel pump and
injectors.

Bulb Replacement
High Intensity Discharge Headlamps (HID)
—
If Equipped
The headlamps are a type of high voltage
discharge tube. High voltage can remain in
the circuit even with the headlamp switch off
and the key removed. Because of this, you
should not attempt to service a headlamp bulb
yourself. If a headlamp bulb fails, take your
vehicle to an authorized dealer for service.
WARNING!
A transient high voltage occurs at the bulb
sockets of High Intensity Discharge (HID)
headlamps when the headlamp switch is
turned ON. It may cause serious electrical
shock or electrocution if not serviced prop-
erly. See your authorized dealer for ser-
vice. NOTE:
On vehicles equipped with High Intensity
Discharge (HID) headlamps, when the head-
lamps are turned on, there is a blue hue to
the lamps. This diminishes and becomes
more white after approximately 10 seconds,
as the system charges.
Halogen Headlamps — If Equipped
1. Open the hood.
2. Turn the low or high beam bulb one–
quarter turn counterclockwise to remove
from housing.
3. Disconnect the electrical connector and replace the bulb.
CAUTION!
Do not touch the new bulb with your fin-
gers. Oil contamination will severely
shorten bulb life. If the bulb comes in
contact with any oily surface, clean the
bulb with rubbing alcohol.
Front Turn Signal Lamp
1. Open the hood.
2. Turn the turn signal bulb one–quarter turncounterclockwise to remove from
housing.
3. Disconnect the electrical connector and replace the bulb.

FUSES
WARNING!
• When replacing a blown fuse, always usean appropriate replacement fuse with
the same amp rating as the original fuse.
Never replace a fuse with another fuse of
higher amp rating. Never replace a
blown fuse with metal wires or any other
material. Failure to use proper fuses may
result in serious personal injury, fire
and/or property damage.
• Before replacing a fuse, make sure that
the ignition is off and that all the other
services are switched off and/or disen-
gaged.
• If the replaced fuse blows again, contact
an authorized dealer.
• If a general protection fuse for safety
systems (air bag system, braking sys-
tem), power unit systems (engine sys-
tem, gearbox system) or steering system
blows, contact an authorized dealer.
General Information
The fuses protect electrical systems against
excessive current.
When a device does not work you must check
the electrical circuit inside the fuse for a
break/melt.
Also please be aware that when using power
outlets for extended periods of time with the
engine off may result in vehicle battery dis-
charge.
Underhood Fuses
The Power Distribution Center is located in
the engine compartment near the battery.
This center contains cartridge fuses, micro
fuses, relays, and circuit breakers. A descrip-
tion of each fuse and component may be
stamped on the inside cover, otherwise the
cavity number of each fuse is stamped on the
