2011 LINCOLN MKZ Service engine soon

WARNING:Do not park, idle, or drive your vehicle in dry grass
or other dry ground cover. The emission system heats up the
engine compartment and exhaust system, which can start a fire.
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.
WARNING:Exhaust leaks may result in entry of harmful and
potentially lethal fumes into the passenger compartment.
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 yourWarranty Guidefor complete emission warranty
information.
On-board diagnostics (OBD-II)
Your vehicle is equipped with a computer that monitors the engine’s
emission control system. This system is commonly known as the
on-board diagnostics system (OBD-II). The OBD-II system protects the
environment by ensuring that your vehicle continues to meet
government emission standards. The OBD-II system also assists your
authorized dealer 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. The 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 been properly closed. SeeEasy Fuel™
“no cap” fuel systemin this chapter.

4. Driving through deep water—the electrical system may be wet.
These temporary malfunctions can be corrected 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 the engine is started. 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. 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 considered not ready for I/M testing.
If the service engine soon
indicator is on or the bulb does not
work, the vehicle may need to be serviced. Refer toOn-board
diagnostics (OBD-II)in this chapter.
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.

GENERAL MAINTENANCE INFORMATION
Why maintain your vehicle?
This guide describes the scheduled maintenance required for your
vehicle. Carefully following this schedule helps protect against major
repair expenses resulting from neglect or inadequate maintenance and
may also help to increase the value of your vehicle when you sell or
trade it.
It is your responsibility to see that all scheduled maintenance is
performed and that the materials used meet Ford engineering
specifications. Failure to perform scheduled maintenance specific in this
guide will invalidate warranty coverage on parts affected by the lack of
maintenance. Be sure receipts for completed maintenance are kept with
the vehicle and confirmation of the work performed is always recorded in
this guide.
Your Ford or Lincoln Mercury dealer has factory-trained technicians who
can perform the required maintenance using genuine Ford parts. They
are committed to meeting your service needs and to assuring your
continuing satisfaction.
Protecting your investment
Maintenance is an investment that will pay dividends in the form of
improved reliability, durability and resale value. To ensure the proper
performance of your vehicle and its emission control systems, it is
imperative that scheduled maintenance be completed at the designated
intervals.
For your convenience, your vehicle is equipped with a message center
which determines the proper oil change service interval. You should
perform the engine oil change as indicated by the instrument cluster
message center. The message center will display ENGINE OIL CHANGE
SOON or OIL CHANGE REQUIRED to indicate when an oil change is
needed. The engine oil change service needs to be completed within two
weeks or 500 miles (800 km) after the OIL CHANGE REQUIRED
message is displayed. Your oil change service interval can be up to one
year or 10,000 miles (16,000 km). Reset your Intelligent Oil Life
Monitor™ after each engine oil and filter change; refer to the
Instrument Clusterchapter.
If your message center is prematurely reset or becomes inoperative, you
should perform the oil change interval at six months or 5,000 miles
(8,000 km) from your last oil change.
Your vehicle is very sophisticated and built with multiple complex
performance systems. Every manufacturer develops these systems using
