The system helps reduce fuel consumption
by automatically stopping and restarting the
engine when your vehicle has stopped. The
engine restarts automatically when you
release the brake pedal.
In some situations, your vehicle may restart
automatically, for example:
• To maintain interior comfort.
• To recharge the battery.
Note:Power assist steering turns off when
the engine is off.
Note:If your vehicle is flex fuel capable,
Auto-Start-Stop will be inhibited for a short
time after a refuel event while the system is
verifying the fuel type being used.
WARNING: Apply the parking brake,
shift into park (P), switch the ignition off
and remove the key before you leave your
vehicle. Failure to follow this instruction
could result in personal injury or death.

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.

Engine Emission Control

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 Ford,
Motorcraft or Ford-authorized parts for
maintenance replacements or for service of
components affecting emission control, such
non-Ford parts should be 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 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 229).
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.
236
Engine Emission Control

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:When plugging into an unfamiliar wall
outlet, let the vehicle charge for several
minutes before leaving it unattended. The
red indicator will illuminate if not charging.
The unit will turn off if breaker or
infrastructure ground fault circuit interrupter
(GFCI) is tripped. You can view vehicle
charging status remotely via the Lincoln Way
App.
Mobile Power Cord Auto-Restart
Auto-restart helps to make sure that your
vehicle will be charged and ready for use
when needed. A charge could be interrupted
if errors are detected. Charging resumes
once the error is no longer detected. The
red indicator illuminates during an error
condition.
The exception to the immediate auto-restart
is when the interruption is due to a charger
ground fault circuit interrupter (GFCI) event.
The charger attempts to restart 15 minutes
after a ground fault circuit interrupter (GFCI)
event. After the fourth attempt to restart, the
charger shuts down and the red indicator
stays on.If the fault persists, do not continue to try to
charge your vehicle. Contact your authorized
dealer.
CARE INSTRUCTIONS
Do not use cleaners or solvents as this could
damage your mobile power cord. Do not
place stress on the charger cables. If unit
overheats, remove the mobile power cord
from direct sunlight.
SAFETY FEATURES
The charger includes the following safety
features to protect against the risk of electric
shock:
• Service Ground Check: The charger
constantly checks for the presence of a
service ground connection. If the service
ground ever fails, the charger red
indicator turns ON and shuts down power
to the vehicle.
• Thermal Event Sensor: Charger module
senses out-of-ordinary thermal events
and decreases the charging current or
shuts the unit down if required.• Ground fault circuit interrupter (GFCI)
Protection: The charger has a ground
fault circuit interrupter (GFCI) reaction
system to protect against electric shock.
If the charger module detects an output
ground fault, it shuts down power to the
output cable and illuminates the red
indicator.
• Insulation: The charger module,
connector, cable assembly, and charge
coupler are completely insulated. There
are no exposed live parts, to protect
against electric shock.
• Unintentional Disconnection: The charge
coupler is designed to minimize
unintentional disconnection. A pilot signal
wire in the cable and charge coupler
eliminates the possibility of electric shock
when not connected to a vehicle or if an
unintended disconnect occurs during a
charge. Disconnection during charging
is safe.

USING ALL-WHEEL DRIVE
WARNING: Vehicles with a higher
center of gravity (utility and four-wheel
drive vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury
and death.
WARNING: Do not become
overconfident in the ability of all-wheel
drive vehicles. Although an all-wheel drive
vehicle may accelerate better than a
two-wheel drive vehicle in low traction
situations, it won't stop any faster than
two-wheel drive vehicles. Always drive at
a safe speed.The intelligent AWD system continuously
monitors vehicle conditions and adjusts the
power distribution between the front and
rear wheels. It combines transparent
all-surface operation with highly capable
all-wheel drive.
The AWD system is always active and
requires no driver input. It is capable of
handling all road conditions including street
and highway driving as well as off-road and
winter driving. You can optimize more AWD
control by selecting different drive modes.
See Selecting a Drive Mode (page 343).
Note:A warning message displays in the
information display when an AWD system
fault is present. See Information Messages
(page 142). A AWD system fault causes the
AWD system to default to rear-wheel drive
only mode. When this warning message
displays, have your vehicle serviced.Note:A warning message displays in the
information display if the AWD system
overheats. See Information Messages
(page 142). This condition could occur if you
operate your vehicle in extreme conditions
with excessive wheel slip, such as deep
sand. To resume normal AWD function as
soon as possible, stop the vehicle in a safe
location and stop the engine for at least 10
minutes. After you restart the engine and the
AWD system adequately cools, the warning
message turns off and normal AWD function
returns.Operating All-Wheel Drive (AWD)
Vehicles With Spare Tires
Do not use a different size spare tire other
than the tire provided. If the mini-spare tire
is installed, the AWD system will disable and
enter rear-wheel drive only mode to protect
driveline components. Some limited AWD
traction could be provided if the mini-spare
is installed on one of the front wheels. If you
are in driving conditions where limited AWD
traction is needed while the mini-spare is
installed, it is recommended the mini-spare
be installed on the front axle.
