2017 LINCOLN MKZ Emissions control system

Powertrain Fault
Illuminates when a powertrain or
an AWD fault has been detected.
Contact your authorized dealer as
soon as possible.
Service Engine Soon If the service engine soon indicator
light stays illuminated after the
engine is started, it indicates that
the On Board Diagnostics system (OBD) has
detected a malfunction of the vehicle
emissions control system. Refer to On board
diagnostics (OBD) in the Fuel and Refueling
chapter for more information about having
your vehicle serviced. See Emission Control
System (page 170).
If the light is blinking, engine misfire is
occurring which could damage your catalytic
converter. Drive in a moderate fashion (avoid
heavy acceleration and deceleration) and
have your vehicle serviced immediately. WARNING
Under engine misfire conditions,
excessive exhaust temperatures could
damage the catalytic converter, the fuel
system, interior floor coverings or other
vehicle components, possibly causing a fire.
Have an authorized dealer service your
vehicle immediately. The service engine soon indicator light
illuminates when the ignition is first turned
on prior to engine start to check the bulb and
to indicate whether the vehicle is ready for
Inspection/Maintenance (I/M) testing.
Normally, the service engine soon light will
stay on until the engine is cranked, then turn
itself off if no malfunctions are present.
However, if after 15 seconds the service
engine soon light blinks eight times, it means
that the vehicle is not ready for I/M testing.
See
Emission Control System (page 170).
Stability Control It will flash when the system is
active. If it remains illuminated or
does not illuminate when you
switch the ignition on, this indicates a
malfunction. During a malfunction the system
will switch off. Have the system checked by
your authorized dealer immediately.
See
Using Stability Control (page 197).
Stability Control Off It will illuminate when you switch
the system off. It will go out when
you switch the system back on or
when you switch the ignition off. See Using
Stability Control
(page 197).
Trunk Ajar Displays when the ignition is on
and the trunk is not completely
closed.

•
Do not turn off the ignition while your
vehicle is moving, especially at high
speeds.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
The scheduled maintenance items listed in
scheduled maintenance information are
essential to the life and performance of your
vehicle and to its emissions system. See
Scheduled Maintenance (page 495).
If you use parts 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 the 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 of temporary malfunctions are:
• the vehicle has run out of fuel—the
engine may misfire or run poorly
• poor fuel quality or water in the fuel—the
engine may misfire or run poorly
• the fuel fill inlet may not have closed
properly.
See Refueling (page 167).
• driving through deep water—the
electrical system may be wet.

MKZ (CC9) Canada/United States of America, enUSA, First Printing Fuel and Refueling

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/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/Maintenance
(I/M) Testing
Some state/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,
you may need to have the vehicle
serviced. See On-Board Diagnostics (OBD-II).
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, your
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 the vehicle is
ready for I/M testing.
The OBD-II system monitors 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 may
need to perform the following driving cycle
consisting of mixed city and highway driving:
Drive on an expressway or highway for a
steady 15 minutes, followed by 20 minutes
of stop-and-go driving with at least four
30-second idle periods.
Allow the vehicle to sit for at least eight hours
without starting the engine. Then, start the
engine and complete the above driving
cycle. The engine must warm up to its normal
operating temperature. Once started, do not
turn off the engine until the above driving
cycle is complete. If the vehicle is still not
ready for I/M testing, you will have to repeat
the above driving cycle.

GENERAL MAINTENANCE
INFORMATION
Why Maintain Your Vehicle?
Carefully following the maintenance
schedule helps protect against major repair
expenses resulting from neglect or
inadequate maintenance and may help to
increase the value of your vehicle when you
sell or trade it. Keep all receipts for
completed maintenance with your vehicle.
We have established regular maintenance
intervals for your vehicle based upon
rigorous testing. It is important that you have
your vehicle serviced at the proper times.
These intervals serve two purposes; one is
to maintain the reliability of your vehicle and
the second is to keep your cost of owning
your vehicle down.
It is your responsibility to have all scheduled
maintenance performed and to make sure
that the materials used meet the
specifications identified in this owner's
manual. See Capacities and Specifications
(page 367).
Failure to perform scheduled maintenance
invalidates warranty coverage on parts
affected by the lack of maintenance.
Why Maintain Your Vehicle at Your
Dealership?
Factory-Trained Technicians
Service technicians participate in extensive
factory-sponsored certification training to
help them become experts on the operation
of your vehicle. Ask your dealership about
the training and certification their technicians
have received.
Genuine Ford and Motorcraft® Replacement
Parts
Dealerships stock Ford, Motorcraft and
Ford-authorized branded re-manufactured
replacement parts. These parts meet or
exceed our specifications. Parts installed at
your dealership carry a nationwide 24-month
or unlimited mile (kilometer) parts and labor
limited warranty.
If you do not use Ford authorized parts they
may not meet our specifications and
depending on the part, it could affect
emissions compliance.
Convenience
Many dealerships have extended evening
and Saturday hours to make your service
visit more convenient and they offer one stop
shopping. They can perform any services
that are required on your vehicle, from
general maintenance to collision repairs.
Note:
Not all dealers have extended hours
or body shops. Please contact your dealer
for details.
Protecting Your Investment
Maintenance is an investment that pays
dividends in the form of improved reliability,
durability and resale value. To maintain the
proper performance of your vehicle and its
emission control systems, make sure you
have scheduled maintenance performed at
the designated intervals.
