2021 LINCOLN AVIATOR ignition

For longer, trouble-free operation, keep the
top of the battery clean and dry and the
battery cables tightly fastened to the battery
terminals. If any corrosion is present on the
battery or terminals, remove the cables from
the terminals and clean with a wire brush.
You can neutralize the acid with a solution
of baking soda and water.
We recommend that you disconnect the
negative battery cable terminal from the
battery if you plan to store your vehicle for
an extended period.
Note:
If you only disconnect the negative
battery cable terminal, make sure it is
isolated or placed away from the battery
terminal to avoid unintended connection or
arcing.
If you replace the battery make sure it
matches the electrical requirements of your
vehicle. If you disconnect or replace the battery and
your vehicle has an automatic transmission,
it must relearn its adaptive strategy. Because
of this, the transmission may shift firmly when
first driven. This is normal operation while
the transmission fully updates its operation
to optimum shift feel.
Battery Management System (If Equipped)
The battery management system monitors
battery conditions and takes actions to
extend battery life. If excessive battery drain
is detected, the system temporarily disables
some electrical systems to protect the
battery.
Systems included are:
• Heated rear window.
• Heated seats.
• Climate control.
• Heated steering wheel.
• Audio unit.
• Navigation system. A message may appear in the information
displays to alert you that battery protection
actions are active. These messages are only
for notification that an action is taking place,
and not intended to indicate an electrical
problem or that the battery requires
replacement.
After battery replacement, or in some cases
after charging the battery with an external
charger, the battery management system
requires eight hours of vehicle sleep time to
relearn the battery state of charge. During
this time your vehicle must remain fully
locked with the ignition switched off.
Note:
Prior to relearning the battery state of
charge, the battery management system
may temporarily disable some electrical
systems.

Electrical Accessory Installation
To make sure the battery management
system works correctly, do not connect an
electrical device ground connection directly
to the battery negative post. This can cause
inaccurate measurements of the battery
condition and potential incorrect system
operation.
Note:
If you add electrical accessories or
components to the vehicle, it may adversely
affect battery performance and durability.
This may also affect the performance of
other electrical systems in the vehicle.
Remove and Reinstall the Battery
To disconnect or remove the battery, do the
following:
1. Apply the parking brake and switch the ignition off.
2. Switch all electrical equipment off, for example lights and radio.
3. Wait a minimum of two minutes before disconnecting the battery. Note:
The engine management system has
a power hold function and remains powered
for a period of time after you switch the
ignition off. This is to allow diagnostic and
adaptive tables to be stored. Disconnecting
the battery without waiting can cause
damage not covered by the vehicle
Warranty.
4. Disconnect the negative battery cable terminal.
5. Disconnect the positive battery cable terminal.
6. Remove the battery securing clamp.
7. Remove the battery.
8. To install, reverse the removal procedure.
Note: Before reconnecting the battery, make
sure the ignition remains switched off.
Note: Make sure the battery cable terminals
are fully tightened. If you disconnect or replace the vehicle
battery, you must reset the following
features:
•
Window bounce-back. See Power
Windows (page 119).
• Clock Settings.
• Pre-set radio stations.
Battery Disposal Make sure that you dispose of old
batteries in an environmentally
friendly way. Seek advice from
your local authority about recycling old
batteries.
ADJUSTING THE HEADLAMPS
Vertical Aim Adjustment
If your vehicle has been involved in a crash,
have the aim of the headlamp beam checked
by an authorized dealer.

2. Use a suitable tool, for example a
screwdriver, to carefully move the tab on
the end cap.
3. Pull the end cap to release the rubber insert
4. To install, reverse the removal procedure.
CHANGING THE REAR WIPER
BLADES
You can improve poor wiper quality by
cleaning the wiper blades and the
windshield.
Replace the wiper blades at least annually
for optimum performance. 1.
Switch your vehicle ignition on and off to
move the wiper arm to the service
position.
2. Lift the wiper arm and then press the wiper blade locking buttons together.
Note: Do not hold the wiper blade to lift the
wiper arm.
3. Slightly rotate the wiper blade. 4. Remove the wiper blade.
Note:
Make sure that the wiper arm does
not spring back against the glass when the
wiper blade is not attached.
5. To install, reverse the removal procedure.
Note: Make sure that the wiper blade locks
into place.
CHANGING A BULB
LED Lamps
LED lamps are not serviceable. See an
authorized dealer if they fail.

•
Do not allow wax to come in contact with
any non-body (low-gloss black) colored
trim. The wax will discolor or stain the
parts over time.
•Roof racks.
• Bumpers.
• Grained door handles.
• Side moldings.
• Mirror housings.
• Windshield cowl area.
• Do not apply wax to glass areas.
• After waxing, your car's paint should feel
smooth, and be free of streaks and
smudges.
CLEANING THE ENGINE
Engines are more efficient when they are
clean because grease and dirt buildup keep
the engine warmer than normal. When washing:
•
Take care when using a power washer
to clean the engine. The high-pressure
fluid could penetrate the sealed parts
and cause damage.
• Do not spray a hot engine with cold water
to avoid cracking the engine block or
other engine components.
• Spray Motorcraft Engine Shampoo and
Degreaser on all parts that require
cleaning and pressure rinse clean. In
Canada, use Motorcraft Engine Shampoo.
Note: If your vehicle has an engine cover
remove the cover before application of
Motorcraft Engine Shampoo and Degreaser.
Immediately rinse away any over spray.
• Never wash or rinse the engine while it
is hot or running; water in the running
engine may cause internal damage.
• Never wash or rinse any ignition coil,
spark plug wire or spark plug well, or the
area in and around these locations.
• Cover the battery, power distribution box,
and air filter assembly to prevent water
damage when cleaning the engine. CLEANING THE WINDOWS AND
WIPER BLADES
Car wash chemicals and environmental
fallout can result in windshield and wiper
blade contamination. Dirty windshield and
wipers will result in poor windshield wiper
operation. Keep the windshield and wiper
blades clean to maintain windshield wiper
performance.
To clean the windshield and wiper blades:
•
Clean the windshield with a non-abrasive
glass cleaner. When cleaning the interior
of the windshield, avoid getting any glass
cleaner on the instrument panel or door
panels. Wipe any glass cleaner off these
surfaces immediately.
• For windshields contaminated with tree
sap, chemicals, wax or bugs, clean the
entire windshield using steel wool (no
greater than 0000 grade) in a circular
motion and rinse with water.
• Clean the wiper blades with isopropyl
rubbing alcohol or windshield washer
concentrate.
