2021 LINCOLN NAUTILUS ignition

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 off.
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.
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
The headlamps on your vehicle are properly
aimed at the assembly plant. If your vehicle
has been involved in a crash, have the aim
of the headlamp beam checked by an
authorized dealer.

center from the ground and mark an 8 ft
(2.4 m)
horizontal reference line on the
vertical wall or screen at this height.

Cleaning Wheels
Only use a recommended wheel and tire
cleaner to clean the wheels weekly. For
additional information and assistance, we
recommend that you contact an authorized
dealer.
1.
Use a sponge to remove heavy deposits
of dirt and brake dust.
2. Rinse well after cleaning.
Note: Do not apply a cleaning chemical to
warm or hot wheel rims and covers.
If you intend on parking your vehicle for an
extended period after cleaning the wheels
with a wheel cleaner, drive your vehicle for
a few minutes before parking your vehicle.
This reduces the risk of corrosion of the
brake discs, brake pads and linings.
Do not clean the wheels when they are hot.
Note: Some car washes could damage
wheel rims and covers.
Note: Using non-recommended cleaners,
harsh cleaning products, chrome wheel
cleaners or abrasive materials could
damage wheel rims and covers. Cleaning the Engine Compartment
Use a vacuum cleaner to remove debris from
the screen area below windshield.
Note:
If you are not familiar with the parts
around the engine do not wash the engine
compartment. Avoid frequent engine
washes.
When washing the engine compartment:
• Never wash or rinse the engine while it
is hot or running.
• Never wash or rinse any ignition coil,
spark plug wire or spark plug well.
• Cover the battery, power distribution box,
and air filter assembly to prevent water
damage.
Note: If your vehicle has an engine cover
remove the cover before application of
shampoo and degreaser.
• Spray an approved engine shampoo and
degreaser on all parts that require
cleaning and rinse with water. Cleaning Stripes or Graphics
It is recommended to wash your vehicle by
hand however, pressure washing may be
used under the following conditions:
•
Use a spray with a 40° wide spray angle
pattern.
• Keep the nozzle at a 12 in (305 mm)
distance and 90° angle to your vehicle's
surface.
• Do not use water pressure higher than
2,000 psi (14,000 kPa)
.
• Do not use water hotter than 179°F (82°C).
Note: Holding the pressure washer nozzle
at an angle to the vehicle's surface may
damage graphics and cause the edges to
peel away from the vehicle's surface.
Cleaning Camera Lenses and Sensors
We recommend that you only use lukewarm
or cold water and a soft cloth to clean the
camera lens and sensors.
Note: Do not pressure wash camera lens
and sensors.
