engine LINCOLN MKZ HYBRID 2017 Service Manual

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.
Fuel Freshness Mode (If Equipped)
This helps keep the fuel system functional
and the fuel fresh.
If you mainly use your vehicle in electric
power mode without refueling, the gasoline
in the fuel tank may become stale due to
aging. Stale gasoline can damage the
engine and fuel system.
Your vehicle automatically switches to fuel
freshness mode if you do not refuel your
vehicle with fresh fuel within an 18-month
period. Fuel freshness mode protects your
vehicle from potential engine and fuel system
damage caused by using stale fuel.
Note: If you do not add new fuel during an
18-month period, fuel freshness mode will
use fuel until approximately 1.2 gal (4.5 L) of
fuel remains in the fuel tank. During fuel freshness mode:
•
The information display will indicate fuel
freshness mode is active.
• The vehicle will only run in hybrid mode.
EV Now mode will not be available.
• Most of the plug-in power will be stored
until fuel freshness mode is completed.
Note: EV Now mode resumes when less than
1.2 gal (4.5 L) of fuel remains in the fuel tank.
Note: When the fuel level is less than
one-quarter full, refueling your vehicle will
end fuel freshness mode.
Note: We recommend you use a fuel
stabilizer if you use less than a full tank of
fuel during an 18-month period.
RUNNING OUT OF FUEL
Avoid running out of fuel because this
situation may have an adverse effect on
vehicle components.
If you have run out of fuel: •
To start the vehicle with a keyless
ignition, just start the engine. Crank time
will be longer than usual.
• Normally, adding 1 gallon (3.8 liters) of
fuel is enough to restart the vehicle. If the
vehicle is out of fuel and on a steep
grade, more than 1 gallon (3.8 liters) may
be required.
• The service engine soon indicator may
come on.
Refilling With a Portable Fuel Container WARNINGS
Do not insert the nozzle of portable
fuel containers or aftermarket funnels
into the capless fuel system. This could
damage the fuel system and its seal, and
may cause fuel to run onto the ground
instead of filling the tank, which could result
in serious personal injury. 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. 177
MKZ Hybrid (CC9) Hybrid Electric Vehicle (HEV), Canada/United States of America, enUSA, First Printing Fuel and Refueling

The funnel is located in the rear of the
vehicle, inside the load compartment,
underneath the load floor carpet and is
accessible from the trunk.
1. Locate the portable funnel that comes
with your vehicle. 2. Slowly insert the funnel into the capless
fuel system. 3.
Fill the vehicle with fuel from the portable
fuel container.
4. When done, clean the funnel or properly
dispose of it. Extra funnels can be
purchased from your authorized dealer
if you choose to dispose of the funnel.
REFUELING WARNINGS
Do not overfill the fuel tank. The
pressure in an overfilled tank may
cause leakage and lead to fuel spray and
fire. WARNINGS
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. Do not remove the fuel pump nozzle
from its fully inserted position when
refueling. 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. 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. Wait at least 10 seconds before
removing the fuel pump nozzle to allow
any residual fuel to drain into the fuel tank.

FUEL CONSUMPTION
Note:
The amount of usable fuel in the empty
reserve varies and should not be relied upon
to increase driving range. When refueling
your vehicle after the fuel gauge indicates
empty, you might not be able to refuel the
full amount of the advertised capacity of the
fuel tank due to the empty reserve still
present in the tank.
Empty reserve is the amount of fuel
remaining in the tank after the fuel gauge
indicates empty. Do not rely on this fuel for
driving. The usable capacity of the fuel tank
is the amount of fuel that can be put into the
tank after the gauge indicates empty. The
advertised capacity is the total fuel tank size
– it is the combined usable capacity plus the
empty reserve.
Filling the Tank
For consistent results when filling the fuel
tank: •
Turn the ignition off before fueling; an
inaccurate reading results if the engine
is left running.
• Use the same fill rate (low-medium-high)
each time the tank is filled.
• Allow no more than two automatic
click-offs when filling.
Results are most accurate when the filling
method is consistent.
Calculating Fuel Economy
Do not measure fuel economy during the
first 1000 miles (1600 kilometers) of driving
(this is your engine ’s break-in period); a more
accurate measurement is obtained after
2000 miles - 3000 miles (3200 kilometers -
4800 kilometers). Also, fuel expense,
frequency of fill ups or fuel gauge readings
are not accurate ways to measure fuel
economy.
1. Fill the fuel tank completely and record the initial odometer reading.
2. Each time you fill the tank, record the amount of fuel added. 3.
After at least three to five tank fill ups, fill
the fuel tank and record the current
odometer reading.
4. Subtract your initial odometer reading from the current odometer reading.
5. Calculate fuel economy by dividing miles
traveled by gallons used (For Metric:
Multiply liters used by 100, then divide
by kilometers traveled).
Keep a record for at least one month and
record the type of driving (city or highway).
This provides an accurate estimate of the
vehicle ’s fuel economy under current driving
conditions. Additionally, keeping records
during summer and winter show how
temperature impacts fuel economy. In
general, lower temperatures mean lower fuel
economy.

EMISSION CONTROL SYSTEM
WARNINGS
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. 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
dealer inspect your vehicle immediately. Do
not drive if you smell exhaust fumes. Your vehicle is equipped with various
emission control components and a catalytic
converter that will enable your vehicle to
comply with applicable exhaust emission
standards. To make sure that the catalytic
converter and other emission control
components continue to work properly:
•
Use only the specified fuel listed.
• Avoid running out of fuel. •
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 479).
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 180).
• 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/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
185
MKZ Hybrid (CC9) Hybrid Electric Vehicle (HEV), Canada/United States of America, enUSA, First Printing Fuel and Refueling

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.
