Lincoln Aviator (2023 year). Manual in english - page 14

Answer

Question

In order to make sure that the climate control system can begin heating

the cabin or defrosting the windshield as soon as you request it, the

engine coolant temperature has to be kept sufficiently hot. Keeping

the engine on is required to maintain the correct coolant temperature.

Why does my engine stay on when it is extremely cold outside?

Your hybrid vehicle can use E15 fuel (15% ethanol, 85% gasoline), but

you could notice slightly reduced fuel economy because ethanol

contains less energy per gallon than gasoline. Your hybrid vehicle is

not designed to use E85 (85% ethanol).

Can I put E15 or E85 in my vehicle, and how will it affect my fuel

economy?

The high voltage battery system is designed to last the life of the

vehicle and requires no maintenance.

How long will my high voltage battery last? Does it need maintenance?

SAFETY PRECAUTIONS

WARNING: 

Do not overfill the fuel

tank. The pressure in an overfilled tank
may cause leakage and lead to fuel spray
and fire.

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: 

Fuels can cause serious

injury or death if misused or mishandled.

WARNING: 

Fuel may contain

benzene, which is a cancer-causing agent.

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.

Follow these guidelines when refueling:

•

Extinguish all smoking materials and any
open flames before refueling your
vehicle.

•

Always switch the engine off before
refueling.

•

Automotive fuels can be harmful or fatal
if swallowed. Fuel is highly toxic and if
swallowed can cause death or permanent
injury. If fuel is swallowed immediately
call a physician, even if no symptoms are
immediately apparent. The toxic effects
of fuel may not be apparent for hours.

•

Avoid inhaling fuel vapors.  Inhaling fuel
vapor can lead to eye and respiratory
tract irritation.  In severe cases, excessive
or prolonged breathing of fuel vapor can
cause serious illness and permanent
injury.

•

Avoid getting fuel in your eyes. If you
splash fuel in your eyes, immediately
remove contact lenses (if worn), flush with
water for 15 minutes and seek medical
attention.  Failure to seek proper medical
attention could lead to permanent injury.

•

Fuels can be harmful if absorbed through
the skin. If you splash fuel on your skin,
clothing or both, promptly remove
contaminated clothing and thoroughly
wash your skin with soap and water.
Repeated or prolonged skin contact
causes skin irritation.

•

Be particularly careful if you are taking
Antabuse or other forms of Disulfiram for
the treatment of alcoholism. Breathing
fuel vapors could cause an adverse
reaction, serious personal injury or
sickness. Immediately call a physician if
you experience any adverse reactions.

FUEL QUALITY

Choosing the Right Fuel

E161513

E161513

Your vehicle is designed to operate on
regular unleaded gasoline with a minimum
pump (R+M)/2 octane rating of 87.

Some fuel stations, particularly those in high
altitude areas, offer fuels posted as regular
unleaded gasoline with an octane rating
below 87. The use of these fuels could result
in engine damage that is not covered by the
vehicle warranty.

For best overall vehicle and engine
performance, premium fuel with an octane
rating of 91 or higher is recommended. The
performance gained by using premium fuel
is most noticeable in hot weather as well as
other conditions, for example when towing
a trailer.  See 

Towing

 (page 354).

Do not be concerned if the engine
sometimes knocks lightly.  However, if the
engine knocks heavily while using fuel with
the recommended octane rating, contact an
authorized dealer to prevent any engine
damage.

We recommend Top Tier detergent
gasolines, where available to help minimize
engine deposits and maintain optimal vehicle
and engine performance. For additional
information, refer to www.toptiergas.com.

Note:

Use of any fuel for which the vehicle

was not designed can impair the emission
control system, cause loss of vehicle
performance, and cause damage to the
engine which may not be covered by the
vehicle Warranty.

Do not use:

•

Diesel fuel.

•

Fuels containing kerosene or paraffin.

•

Fuel containing more than 15% ethanol
or E85 fuel.

•

Fuels containing methanol.

•

Fuels containing metallic-based additives,
including manganese-based compounds.

•

Fuels containing the octane booster
additive, methylcyclopentadienyl
manganese tricarbonyl (MMT).

•

Leaded fuel; using leaded fuel is
prohibited by law.

The use of fuels with metallic compounds
such as methylcyclopentadienyl manganese
tricarbonyl (commonly known as MMT), which
is a manganese-based fuel additives impair
engine performance and affect the emission
control system.

FUEL FILLER FUNNEL LOCATION

The fuel filler funnel is in the spare wheel
storage tray.

224

Fuel and Refueling

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 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.

233

Fuel and Refueling

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.

234

Engine Emission Control

•

An open or pinched sensor hose.

•

Incorrect engine oil level.

•

Incorrect fuel for climatic conditions.

•

Incorrect engine oil viscosity for climactic
conditions.

Note:

Some vehicles have a lifetime fuel filter

that is integrated with the fuel tank. Regular
maintenance or replacement is not needed.

Note:

If these checks do not help you correct

the concern, have your vehicle checked as
soon as possible.

Noise Emissions Warranty, Prohibited
Tampering Acts and Maintenance

On January 1, 1978, Federal regulation
became effective governing the noise
emission on trucks over 10,000 lb (4,536 kg)
Gross Vehicle Weight Rating (GVWR). The
preceding statements concerning prohibited
tampering acts and maintenance, and the
noise warranty found in the Warranty Guide,
are applicable to complete chassis cabs over
10,000 lb (4,536 kg) GVWR.

CATALYTIC CONVERTER

WARNING: 

Do not park, idle or drive

your vehicle on dry grass or other dry
ground cover. The emission system heats
up the engine compartment and exhaust
system, creating the risk of fire.

WARNING: 

The normal operating

temperature of the exhaust system is very
high. Never work around or attempt to
repair any part of the exhaust system until
it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short period
of engine operation and stays hot after the
engine is switched off.

WARNING: 

Exhaust leaks may result

in entry of harmful and potentially lethal
fumes into the passenger compartment. If
you smell exhaust fumes inside your
vehicle, have your vehicle inspected
immediately. Do not drive if you smell
exhaust fumes.

Your vehicle has various emission control
components and a catalytic converter that
enables it to comply with applicable exhaust
emission standards.

To make sure that the catalytic converter and
other emission control components continue
to work properly:

•

Do not crank the engine for more than
10 seconds at a time.

•

Do not run the engine with a spark plug
lead disconnected.

•

Do not push-start or tow-start your
vehicle. Use booster cables.  See 

Jump

Starting the Vehicle

 (page 366).

•

Use only the specified fuel listed.

•

Do not switch the ignition off when your
vehicle is moving.

•

Avoid running out of fuel.

•

Have the items listed in scheduled
maintenance information performed
according to the specified schedule.

Note:

Resulting component damage may

not be covered by the vehicle Warranty.

235

Engine Emission Control

The scheduled maintenance items listed in
scheduled maintenance information are
essential to the life and performance of your
vehicle and to its emissions system.

If you use anything other than Ford,
Motorcraft or Ford-authorized parts for
maintenance replacements or for service of
components affecting emission control, such
non-Ford parts should be equivalent to
genuine Ford Motor Company parts in
performance and durability.

Illumination of the service engine soon
indicator, charging system warning light or
the temperature warning light, fluid leaks,
strange odors, smoke or loss of engine
power could indicate that the emission
control system is not working properly.

An improperly operating or damaged exhaust
system may allow exhaust to enter the
vehicle. Have a damaged or improperly
operating exhaust system inspected and
repaired immediately.

Do not make any unauthorized changes to
your vehicle or engine. By law, vehicle
owners and anyone who manufactures,
repairs, services, sells, leases, trades
vehicles, or supervises a fleet of vehicles are
not permitted to intentionally remove an
emission control device or prevent it from
working. Information about your vehicle’s
emission system is on the Vehicle Emission
Control Information Decal located on or near
the engine. This decal also lists engine
displacement.

Please consult your warranty information for
complete details.

On-Board Diagnostics (OBD-II)

Your vehicle has a computer known as the
on-board diagnostics system (OBD-II) that
monitors the engine’s emission control
system. The system protects the environment
by making sure that your vehicle continues
to meet government emission standards. The
OBD-II system also assists a service
technician in properly servicing your vehicle.

When the service engine soon
indicator illuminates, the OBD-II
system has detected a malfunction.

Temporary malfunctions may cause the
service engine soon indicator to illuminate.
Examples are:

1.

Your vehicle has run out of fuel—the
engine may misfire or run poorly.

2. Poor fuel quality or water in the fuel—the

engine may misfire or run poorly.

3. The fuel fill inlet may not have closed

properly.  See 

Refueling

 (page 229).

4. Driving through deep water—the

electrical system may be wet.

You can correct these temporary
malfunctions by filling the fuel tank with good
quality fuel, properly closing the fuel fill inlet
or letting the electrical system dry out. After
three driving cycles without these or any
other temporary malfunctions present, the
service engine soon indicator should stay off
the next time you start the engine. A driving
cycle consists of a cold engine startup
followed by mixed city and highway driving.
No additional vehicle service is required.

236

Engine Emission Control

If the service engine soon indicator remains
on, have your vehicle serviced at the first
available opportunity. Although some
malfunctions detected by the OBD-II may not
have symptoms that are apparent, continued
driving with the service engine soon indicator
on can result in increased emissions, lower
fuel economy, reduced engine and
transmission smoothness and lead to more
costly repairs.

Readiness for Inspection and
Maintenance (I/M) Testing

Some state and provincial and local
governments may have
Inspection/Maintenance (I/M) programs to
inspect the emission control equipment on
your vehicle. Failure to pass this inspection
could prevent you from getting a vehicle
registration.

If the service engine soon indicator
is on or the bulb does not work,
your vehicle may need service.

See On-Board Diagnostics.

Your vehicle may not pass the I/M test if the
service engine soon indicator is on or not
working properly (bulb is burned out), or if
the OBD-II system has determined that some
of the emission control systems have not
been properly checked. In this case, the
vehicle is not ready for I/M testing.

If the vehicle’s engine or transmission has
just been serviced, or the battery has
recently run down or been replaced, the
OBD-II system may indicate that the vehicle
is not ready for I/M testing. To determine if
the vehicle is ready for I/M testing, turn the
ignition key to the on position for 15 seconds
without cranking the engine. If the service
engine soon indicator blinks eight times, it
means that the vehicle is not ready for I/M
testing; if the service engine soon indicator
stays on solid, it means that your vehicle is
ready for I/M testing.

The OBD-II system checks the emission
control system during normal driving. A
complete check may take several days.

If the vehicle is not ready for I/M testing, you
can perform the following driving cycle
consisting of mixed city and highway driving:

1.

15 minutes of steady driving on an
expressway or highway followed by 20
minutes of stop-and-go driving with at
least four 30-second idle periods.

2. Allow your vehicle to sit for at least eight

hours with the ignition off. Then, start the
vehicle and complete the above driving
cycle. The vehicle must warm up to its
normal operating temperature. Once
started, do not turn off the vehicle until
the above driving cycle is complete.

If the vehicle is still not ready for I/M testing,
you need to repeat the above driving cycle.
