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.

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 Lincoln,
Motorcraft or Lincoln-authorized parts for
maintenance replacements or for service of
components affecting emission control, such
non-Lincoln parts should be equivalent to
genuine Lincoln 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 214).
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.

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.

Note:
Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the engine
cooling or heating systems. Resulting
component damage may not be covered by
the vehicle Warranty.
It is very important to use prediluted coolant
approved to the correct specification in order
to avoid plugging the small passageways in
the engine cooling system. See Capacities
and Specifications (page 435). Do not mix
different colors or types of coolant in your
vehicle. Mixing of engine coolants or using
an incorrect coolant may harm the engine or
cooling system components and may not be
covered by the vehicle Warranty.
Note: If prediluted coolant is not available,
use the approved concentrated coolant
diluting it to 50/50 with distilled water.
See
Capacities and Specifications (page 435).
Using water that has not been deionised
may contribute to deposit formation,
corrosion and plugging of the small cooling
system passageways. Note:
Coolants marketed for all makes and
models may not be approved to our
specifications and may cause damage to
the cooling system. Resulting component
damage may not be covered by the vehicle
Warranty.
If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
To top up the coolant level do the following:
1. Unscrew the cap slowly. Any pressure escapes as you unscrew the cap.
2. Add prediluted coolant approved to the correct specification. See Capacities and
Specifications
(page 435).
3. Add enough prediluted coolant to reach
the correct level.
4. Replace the coolant reservoir cap. Turn the cap clockwise until it contacts the
hard stop.
5. Check the coolant level in the coolant reservoir the next few times you drive
your vehicle. If necessary, add enough
prediluted engine coolant to bring the
coolant level to the correct level. If you have to add more than
1.1 qt (1 L) of
engine coolant per month, have your vehicle
checked as soon as possible. Operating an
engine with a low level of coolant can result
in engine overheating and possible engine
damage.
In case of emergency, you can add a large
amount of water without engine coolant in
order to reach a vehicle service location. In
this instance, qualified personnel:
1. Must drain the cooling system.
2. Chemically clean the coolant system.
3. Refill with engine coolant as soon as possible.
Water alone, without engine coolant, can
cause engine damage from corrosion,
overheating or freezing.
Do not use the following as a coolant
substitute:
• Alcohol.
• Methanol.
• Brine.
• Any coolant mixed with alcohol or
methanol antifreeze.
