REPLACEMENT PARTS
RECOMMENDATION
We have built your vehicle to the highest
standards using quality parts. We
recommend that you demand the use of
genuine Ford and Motorcraft parts whenever
your vehicle requires scheduled
maintenance or repair. You can clearly
identify genuine Ford and Motorcraft parts
by looking for the Ford, FoMoCo or
Motorcraft branding on the parts or their
packaging.
Scheduled Maintenance and
Mechanical Repairs
One of the best ways for you to make sure
that your vehicle provides years of service
is to have it maintained in line with our
recommendations using parts that conform
to the specifications detailed in this Owner’
s
Manual. Genuine Ford and Motorcraft parts
meet or exceed these specifications. Collision Repairs
We hope that you never experience a
collision, but accidents do happen. Genuine
Ford replacement collision parts meet our
stringent requirements for fit, finish, structural
integrity, corrosion protection and dent
resistance. During vehicle development we
validate that these parts deliver the intended
level of protection as a whole system. A
great way to know for sure you are getting
this level of protection is to use genuine Ford
replacement collision parts.
Warranty on Replacement Parts
Genuine Ford and Motorcraft replacement
parts are the only replacement parts that
benefit from a Lincoln Warranty. Damage
caused to your vehicle as a result of the
failure of non-Ford parts may not be covered
by the Lincoln Warranty. For additional
information, refer to the terms and conditions
of the Lincoln Warranty.
SPECIAL NOTICES
New Vehicle Limited Warranty
For a detailed description of what is covered
by your New Vehicle Limited Warranty, see
your warranty guide that is available online.
For more information, refer to our website
and download your copy of the warranty
guide.
Special Instructions
For your added safety, your vehicle is fitted
with sophisticated electronic controls.
WARNING: You risk death or serious
injury to yourself and others if you do not
follow the instruction highlighted by the
warning symbol. Failure to follow the
specific warnings and instructions could
result in personal injury.

WHAT IS THE CABIN AIR FILTER
The cabin air filter improves the quality of air
in your vehicle by trapping dust, pollen and
other particles.
LOCATING THE CABIN AIR FILTER
You can locate the cabin air filter behind the
glove box.
REPLACING THE CABIN AIR FILTER
Replace the filter at regular intervals. See
Scheduled Maintenance (page 539).
Note: Make sure you have a cabin air filter
installed at all times. This prevents foreign
objects from entering the system. Running
the system without a filter in place could
result in degradation or damage to the
system.
Note: Using an aftermarket cabin air filter
could reduce cabin air filtration and climate
control performance.

•
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 346).
• 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.
224
Navigator (TB9) Canada/United States of America, enUSA, First-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 218).
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.

ESSENTIAL TOWING CHECKS
Follow these guidelines for safe towing:
•
Do not tow a trailer until you drive your
vehicle at least 1,000 mi (1,600 km).
• Consult your local motor vehicle laws for
towing a trailer.
• See any instructions that come with
towing accessories for the proper
installation and adjustment specifications.
• Service your vehicle more frequently if
you tow a trailer.
See Scheduled
Maintenance (page 539).
• If you use a rental trailer, follow the
instructions the rental agency gives you.
You can find information on load
specification terms found on the tire label
and Safety Compliance label as well as
instructions on calculating your vehicle's load
in the Load Carrying chapter. See Load Limit
(page
309).
Remember to account for the trailer tongue
weight as part of your vehicle load when
calculating the total vehicle weight. Trailer Towing Connector (Vehicles
with a Trailer Towing Package and
7–Pin Connector)
When attaching the trailer wiring connector
to your vehicle, only use a proper fitting
connector that works with the vehicle and
trailer functions. Some seven-position
connectors may have the SAE J2863 logo,
which confirms that it is the proper wiring
connector and works correctly with your
vehicle. Function

REDUCED ENGINE PERFORMANCE
WARNING: If you continue to drive
your vehicle when the engine is
overheating, the engine could stop without
warning. Failure to follow this instruction
could result in the loss of control of your
vehicle.
If the engine coolant temperature gauge
needle moves to the upper limit position, the
engine is overheating.
See Gauges (page
127).
You must only drive your vehicle for a short
distance if the engine overheats. The
distance you can travel depends on ambient
temperature, vehicle load and terrain. The
engine continues to operate with limited
power for a short period of time.
If the engine temperature continues to rise,
the fuel supply to the engine reduces. The
air conditioning switches off and the engine
cooling fan operates continually. 1. Gradually reduce your speed and stop
your vehicle as soon as it is safe to do
so.
2. Immediately switch the engine off to prevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level.
See Engine
Coolant Check (page 383).
5. Have your vehicle checked as soon as possible.
ECONOMICAL DRIVING
Fuel economy is affected by several things
such as how you drive, the conditions you
drive under and how you maintain your
vehicle.
There are some things to keep in mind that
may improve your fuel economy:
• Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds.
• Anticipate stops; slowing down may
eliminate the need to stop. •
Combine errands and minimize
stop-and-go driving (When running
errands, go to the furthest destination
first and then work your way back home).
• Close the windows for high-speed
driving.
• Drive at reasonable speeds.
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.
There are also some things you may want to
avoid doing because they reduce your fuel
economy:
• Avoid sudden or hard accelerations.
• Avoid revving the engine before turning
off the car.
• Avoid long idle periods.
• Do not warm up your vehicle on cold
mornings.
• Reduce the use of air conditioning and
heat.
• Avoid using speed control in hilly terrain.

GETTING THE SERVICES YOU
NEED
Warranty repairs to your vehicle must be
performed by an authorized dealer. While
any authorized dealer handling your vehicle
line provides warranty service, we
recommend you return to your selling
authorized dealer who wants to ensure your
continued satisfaction.
Please note that certain warranty repairs
require special training and equipment, so
not all authorized dealers are authorized to
perform all warranty repairs. This means that,
depending on the warranty repair needed,
you may have to take your vehicle to another
authorized dealer.
A reasonable time must be allowed to
perform a repair after taking your vehicle to
the authorized dealer. Repairs are made
using Lincoln or Motorcraft parts, or
remanufactured or other parts that are
authorized by Lincoln.
