System off LINCOLN MKZ HYBRID 2017 Repair Manual

During certain events (such as vehicle
servicing) your low voltage 12-volt battery
may become disconnected or disabled. Once
the battery is reconnected and after driving
the vehicle, the engine may continue to
operate for three to five seconds after the
key is turned to off. This is a normal
condition.
Braking:
Your hybrid is equipped with standard
hydraulic braking and regenerative braking.
Regenerative braking is performed by your
transmission and it captures brake energy
and stores it in your high voltage battery.
Driving to Optimize Fuel Economy
Note:
Having your engine running is not
always an indication of inefficiency. In some
cases, it is actually more efficient than
driving in electric mode. Your fuel economy should improve
throughout your hybrid's break-in period. As
with any vehicle, your driving habits and
accessory usage can significantly impact
your fuel economy. For best results, keep in
mind these tips:
•
Keep the tires properly inflated and only
use the recommended size.
• Aggressive driving increases the amount
of energy required to move your vehicle.
In general, you can achieve better fuel
economy with mild to moderate
acceleration and deceleration. Moderate
braking is particularly important since it
allows you to maximize the energy
captured by the regenerative braking
system.
Additional Tips:
• Do not carry extra loads.
• Be mindful of adding external
accessories that may increase
aerodynamic drag.
• Observe posted speed limits. •
Perform all scheduled maintenance.
• There is no need to wait for your engine
to warm up. The vehicle is ready to drive
immediately after starting.
EV+ Mode
Your vehicle will recognize your frequent
destinations and allow for more EV driving
as you approach them. For example, when
nearing your home it should be easier to stay
in electric mode. The EV indicator will display
EV+ when this mode is active. You should
see this approximately 1/8 mile (200 meters)
from a frequent destination. See Information
Displays (page 108).
Note: Frequent destinations are learned by
your vehicle after two to four weeks of use.
To add a destination immediately, perform
the following process: cycle the ignition on
for 2 seconds, but do not start your vehicle,
then off for 2 seconds. Repeat the process
10 times. This location is now programmed
for EV+. You can clear these destinations
with a Driving History reset through the
Settings menu.

SAFETY PRECAUTIONS
WARNINGS
Do not overfill the fuel tank. The
pressure in an overfilled tank may
cause leakage and lead to fuel spray and
fire. 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. Fuels can cause serious injury or death
if misused or mishandled.
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. Fuel may contain benzene, which is a
cancer-causing agent. WARNINGS
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. Observe the following guidelines when
handling automotive fuel:
•
Extinguish all smoking materials and any
open flames before refueling your
vehicle.
• Always turn off the vehicle before
refueling.
• Automotive fuels can be harmful or fatal
if swallowed. Fuel such as gasoline is
highly toxic and if swallowed can cause
death or permanent injury. If fuel is
swallowed, call a physician immediately,
even if no symptoms are immediately
apparent. The toxic effects of fuel may
not be visible for hours. •
Avoid inhaling fuel vapors. Inhaling too
much fuel vapor of any kind 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 liquid in your eyes. If
fuel is splashed in the eyes, 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 also be harmful if absorbed
through the skin. If fuel is splashed on
the skin, clothing or both, promptly
remove contaminated clothing and wash
skin thoroughly with soap and water.
Repeated or prolonged skin contact with
fuel liquid or vapor causes skin irritation.
• Be particularly careful if you are taking
Antabuse or other forms of Disulfiram for
the treatment of alcoholism. Breathing
gasoline vapors could cause an adverse
reaction, serious personal injury or
sickness. If fuel is splashed on the skin,
wash the affected areas immediately with
plenty of soap and water. Consult a
physician immediately if you experience
any adverse reactions. FUEL QUALITY
Choosing the Right Fuel We recommend regular unleaded gasoline
with a minimum pump (R+M)/2 octane rating
of 87. Some fuel stations offer fuels posted
as regular unleaded gasoline with an octane
rating below 87, particularly in high altitude
areas. We do not recommend fuels with an
octane rating below 87.
Do not use any fuel other than those
recommended because they could lead to
engine damage that may not be covered by
the vehicle Warranty.Note:
Use of any fuel other than those
recommended can impair the emission
control system and cause a loss of vehicle
performance.
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 additive, will
impair engine performance and affect the
emission control system.

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.

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.
