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.
187
MKZ (CC9) Hybrid Electric Vehicle (HEV), Canada/United States of America, enUSA, Edition date: 201905, Second-Printing Engine Emission Control

•
An open or pinched sensor hose.
• Incorrect engine oil level.
• Incorrect fuel for climatic conditions.
• Incorrect engine oil viscosity for climactic
conditions.
Note: Some vehicles have a lifetime fuel filter
that is integrated with the fuel tank. Regular
maintenance or replacement is not needed.
Note: If these checks do not help you correct
the concern, have your vehicle checked as
soon as possible.
Noise Emissions Warranty, Prohibited
Tampering Acts and Maintenance
On January 1, 1978, Federal regulation
became effective governing the noise
emission on trucks over 10,000 lb (4,536 kg)
Gross Vehicle Weight Rating (GVWR). The
preceding statements concerning prohibited
tampering acts and maintenance, and the
noise warranty found in the Warranty Guide,
are applicable to complete chassis cabs over
10,000 lb (4,536 kg)
GVWR. CATALYTIC CONVERTER WARNING:
Do not park, idle or drive
your vehicle on dry grass or other dry
ground cover. The emission system heats
up the engine compartment and exhaust
system, creating the risk of fire. WARNING:
The normal operating
temperature of the exhaust system is very
high. Never work around or attempt to
repair any part of the exhaust system until
it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short period
of engine operation and stays hot after the
engine is switched off. WARNING: 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 vehicle inspected
immediately. Do not drive if you smell
exhaust fumes. Your vehicle has various emission control
components and a catalytic converter that
enables it to comply with applicable exhaust
emission standards.
To make sure that the catalytic converter and
other emission control components continue
to work properly:
•
Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables.
See Jump
Starting the Vehicle (page 267).
• Use only the specified fuel listed.
• Do not switch the ignition off when your
vehicle is moving.
• Avoid running out of fuel.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
Note: Resulting component damage may
not be covered by the vehicle Warranty.
188
MKZ (CC9) Hybrid Electric Vehicle (HEV), Canada/United States of America, enUSA, Edition date: 201905, Second-Printing 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 Lincoln,
Motorcraft or Lincoln-authorized parts for
maintenance replacements or for service of
components affecting emission control, such
non-Lincoln parts should be equivalent to
genuine Lincoln 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 182).
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.
