RUNNING OUT OF FUEL
Running out of fuel can cause damage not
covered by the vehicle Warranty.
If your vehicle runs out of fuel:
• Add a minimum of 1.3 gal (5 L) of fuel to
restart the engine.
• You may need to switch the ignition from
off to on several times after refueling to
allow the fuel system to pump the fuel
from the tank to the engine. When
restarting, cranking time takes a few
seconds longer than normal.
Note:If your vehicle is on a steep slope,
more fuel may be required.
Filling a Portable Fuel Container
WARNING: Flow of fuel through a
fuel pump nozzle can produce static
electricity. This can cause a fire if you are
filling an ungrounded fuel container.Use the following guidelines to avoid
electrostatic charge build-up, which can
produce a spark, when filling an ungrounded
fuel container:
• Only use an approved fuel container to
transfer fuel to your vehicle. Place the
container on the ground when filling it.
• Do not fill a fuel container when it is
inside your vehicle (including the cargo
area).
• Keep the fuel pump nozzle in contact
with the fuel container when filling it.
• Do not use a device that holds the fuel
pump nozzle lever in the fill position.
Adding Fuel From a Portable Fuel
Container
WARNING: Do not insert the nozzle
of a fuel container or an aftermarket funnel
into the fuel filler neck. This may damage
the fuel system filler neck or its seal and
cause fuel to run onto the ground.
WARNING: Do not try to pry open or
push open the capless fuel system with
foreign objects. This could damage the fuel
system and its seal and cause injury to you
or others.
WARNING: Do not dispose of fuel in
the household refuse or the public sewage
system. Use an authorized waste disposal
facility.
When refueling the vehicle fuel tank from a
fuel container, use the fuel filler funnel
included with your vehicle. See Fuel Filler
Funnel Location (page 224).
Note:Do not use aftermarket funnels as they
may not work with the capless fuel system
and can damage it.
When refueling the vehicle fuel tank from a
fuel container, do the following:
1. Fully open the fuel filler door.
2. Fully insert the fuel filler funnel into the
fuel filler inlet.

container.
4. Remove the fuel filler funnel.
5. Fully close the fuel filler door.
6. Clean the fuel filler funnel and place it
back in your vehicle or correctly dispose
of it.
Note:Extra funnels can be purchased from
an authorized dealer if you choose to
dispose of the funnel.

Refueling Your Vehicle
WARNING: When refueling always
shut the engine off and never allow sparks
or open flames near the fuel tank filler
valve. Never smoke or use a cell phone
while refueling. Fuel vapor is extremely
hazardous under certain conditions. Avoid
inhaling excess fumes.
WARNING: The fuel system may be
under pressure. If you hear a hissing sound
near the fuel filler inlet, do not refuel until
the sound stops. Otherwise, fuel may spray
out, which could cause serious personal
injury.
WARNING: Do not pry open the fuel
tank filler valve. This could damage the fuel
system. Failure to follow this instruction
could result in fire, personal injury or death.
WARNING: Do not remove the fuel
pump nozzle from its fully inserted position
when refueling.
WARNING: Stop refueling when the
fuel pump nozzle automatically shuts off
for the first time. Failure to follow this will
fill the expansion space in the fuel tank and
could lead to fuel overflowing.
WARNING: Do not overfill the fuel
tank. The pressure in an overfilled tank
may cause leakage and lead to fuel spray
and fire.
WARNING: Wait at least five seconds
before removing the fuel pump nozzle to
allow any residual fuel to drain into the fuel
tank.
WARNING: Read and follow all the
instructions on the pump island.
1. Fully open the fuel filler door.
2. Select the correct fuel pump nozzle for
your vehicle.

4. Hold the fuel pump nozzle in position B
when refueling. Holding the fuel pump
nozzle in position A can affect the flow

5. Operate the fuel pump nozzle within the
area shown.

6. When the nozzle shuts off, wait at least
5 seconds, then slightly raise the fuel
pump nozzle and slowly remove it.
7. Fully close the fuel filler door.Do not attempt to start the engine if you have
filled the fuel tank with incorrect fuel.
Incorrect fuel use could cause damage that
the vehicle Warranty may not cover. See your
authorized dealer immediately.
Refueling System Warning (If Equipped)
If the fuel tank filler valve does not fully close,
a message could appear in the information
display.
Message
Check Fuel Fill Inlet
If the message appears, do the following:
1. Stop your vehicle as soon as it is safe to
do so and switch the engine off.
2. Shift into park (P) or neutral (N).
3. Apply the parking brake.
4. Fully open the fuel filler door.
5. Check the fuel tank filler valve for any
debris that may be restricting its
movement.
228
Fuel and Refueling

6. Remove any debris from the fuel tank
filler valve.
7. Fully insert a fuel pump nozzle or the fuel
filler funnel provided with your vehicle
into the fuel filler pipe. See Fuel Filler
Funnel Location (page 224). This action
should dislodge any debris that may be
preventing the fuel tank filler valve from
fully closing.
8. Remove the fuel pump nozzle or fuel filler
funnel from the fuel filler pipe.
9. Fully close the fuel filler door.
Note:The message may not immediately
reset. If the message continues to appear
and a warning lamp illuminates, see your
authorized dealer as soon as possible.REFUELING - PLUG-IN HYBRID

FUEL CONSUMPTION
Advertised Capacity
The advertised capacity is the maximum
amount of fuel that you can add to the fuel
tank when the fuel gauge indicates empty.
See Capacities and Specifications (page
465).
In addition, the fuel tank contains an empty
reserve. The empty reserve is an unspecified
amount of fuel that remains in the fuel tank
when the fuel gauge indicates empty.
Note:The amount of fuel in the empty
reserve varies and should not be relied upon
to increase driving range.
Calculating Fuel Economy
Your vehicle calculates fuel economy figures
through the trip computer average fuel
function. See Information Displays (page
136).The first 1,000 mi (1,600 km) of driving is the
break-in period of the vehicle. Resetting
average fuel in your trip computer after
2,000–3,000 mi (3,200–4,800 km) provides
a more accurate measurement.
Conditions Influencing Fuel Efficiency

EMISSION LAW
WARNING: Do not remove or alter
the original equipment floor covering or
insulation between it and the metal floor
of the vehicle. The floor covering and
insulation protect occupants of the vehicle
from the engine and exhaust system heat
and noise. On vehicles with no original
equipment floor covering insulation, do not
carry passengers in a manner that permits
prolonged skin contact with the metal floor.
Failure to follow these instructions may
result in fire or personal injury.
U.S. federal laws and certain state laws
prohibit removing or rendering inoperative
emission control system components. Similar
federal or provincial laws may apply in
Canada. We do not approve of any vehicle
modification without first determining
applicable laws.
Tampering with emissions control
systems including related sensors
or the Diesel Exhaust Fluid system
can result in reduced engine power and the
illumination of the service engine soon light.
Tampering With a Noise Control
System
Federal laws prohibit the following acts:
• Removal or rendering inoperative by any
person other than for purposes of
maintenance.
• Repair or replacement of any device or
element of the design incorporated into
a new vehicle for the purpose of noise
control prior to its sale or delivery to the
ultimate purchaser or while it is in use.
• The use of the vehicle after any person
removes or renders inoperative any
device or element of the design.The U.S. Environmental Protection Agency
may presume to constitute tampering as
follows:
• Removal of hood blanket, fender apron
absorbers, fender apron barriers,
underbody noise shields or acoustically
absorptive material.
• Tampering or rendering inoperative the
engine speed governor, to allow engine
speed to exceed manufacturer
specifications.
If the engine does not start, runs rough,
experiences a decrease in engine
performance, experiences excess fuel
consumption or produces excessive exhaust
smoke, check for the following:
• A plugged or disconnected air inlet
system hose.
• A plugged engine air filter element.
• Water in the fuel filter and water
separator.
• A clogged fuel filter.
• Contaminated fuel.
• Air in the fuel system, due to loose
connections.
