check engine LINCOLN NAUTILUS 2020 Owner's Manual

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.

•
Provides additional engine braking and
extends lower gear operation to enhance
performance for uphill climbs, hilly terrain
or mountainous areas. This increases
engine RPM during engine braking.
• Provides additional lower gear operation
through the automatic transmission shift
strategy.
• Provides gear selection more quickly and
at higher engine speeds.
SelectShift Automatic â„¢ Transmission
Your SelectShift Automatic transmission
gives you the ability to change gears
manually.
Paddle Shifters
With your vehicle in drive (D), the paddle
shifters provide temporary manual control.
They allow you the ability to shift gears
quickly, without taking your hands off the
steering wheel.
The system determines when temporary
manual control is no longer in use and
returns to automatic control. You can achieve extensive manual control
by pressing the sport (S) button.
•
Pull the right paddle (+) to upshift.
• Pull the left paddle (-) to downshift. The instrument cluster displays your currently
selected gear.
The transmission automatically upshifts if
your engine speed is too high or downshift
if your engine speed is too low.
Note:
You can exit manual control by making
another shift button selection drive (D), for
example, or by briefly holding the (+) paddle. Manual Park Release WARNING: When doing this
procedure, you need to take the
transmission out of park (P) which means
your vehicle can roll freely. To avoid
unwanted vehicle movement, always fully
apply the parking brake prior to doing this
procedure. Use wheels chocks if
appropriate. WARNING:
If the parking brake is
fully released, but the brake warning lamp
remains illuminated, the brakes may not
be working properly. Have your vehicle
checked as soon as possible. WARNING:
Do not drive your vehicle
until you verify that the stoplamps are
working.
Use the manual park release to move your
transmission from the park (P) position in the
event of an electrical malfunction or
emergency.

If Your Vehicle Goes Off the Edge of the
Pavement
•
If your vehicle goes off the edge of the
pavement, slow down, but avoid severe
brake application, ease the vehicle back
onto the pavement only after reducing
your speed. Do not turn the steering
wheel too sharply when returning to the
road surface.
• It may be safer to stay on the apron or
shoulder of the road and slow down
gradually before returning to the
pavement. You may lose control if you
do not slow down or if you turn the
steering wheel too sharply or abruptly.
• It often may be less risky to strike small
objects, such as highway reflectors, with
minor damage to your vehicle rather than
attempt a sudden return to the pavement
which could cause the vehicle to slide
sideways out of control or rollover.
Remember, your safety and the safety of
others should be your primary concern. If Your Vehicle Gets Stuck WARNING: Always set the parking
brake fully and make sure you shift the
gearshift lever to first gear. Switch the
ignition off and remove the key whenever
you leave your vehicle. WARNING:
If the parking brake is
fully released, but the brake warning lamp
remains illuminated, the brakes may not
be working properly. Have your vehicle
checked as soon as possible. WARNING:
Do not spin the wheels
at over 34 mph (55 km/h). The tires may
fail and injure a passenger or bystander.
Note: Do not rock the vehicle if the engine
is not at normal operating temperature or
damage to the transmission may occur.
Note: Do not rock the vehicle for more than
a few minutes or damage to the transmission
and tires may occur or the engine may
overheat. If your vehicle gets stuck in mud or snow,
you can rock it out by shifting between
forward and reverse gears, stopping
between shifts, in a steady pattern. Press
lightly on the accelerator in each gear.
If your vehicle has AdvanceTrac
â„¢ with Roll
Stability Controlâ„¢, it may be beneficial to
disengage the AdvanceTrac with Roll
Stability Control system when attempting to
rock the vehicle.
Emergency Maneuvers
• In an unavoidable emergency situation
where a sudden sharp turn must be
made, remember to avoid "over-driving"
your vehicle, for example, turn the
steering wheel only as rapidly and as far
as required to avoid the emergency.
Excessive steering results in less vehicle
control, not more. Additionally, use
smooth variations of the accelerator and
brake pedal pressure if changes in
vehicle speed are necessary. Avoid

GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out and an
authorized dealer should check them. If the
vehicle has continuous vibration or shudder
in the steering wheel while braking, an
authorized dealer should check your vehicle.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See Cleaning the Wheels
(page 350).
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes. Brake Over Accelerator
In the event the accelerator pedal becomes
stuck or entrapped, apply steady and firm
pressure to the brake pedal to slow the
vehicle and reduce engine power. If you
experience this condition, apply the brakes
and bring your vehicle to a safe stop. Switch
the engine off, move the transmission to park
(P) and apply the parking brake. Inspect the
accelerator pedal and the area around it for
any items or debris that may be obstructing
its movement. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.
Emergency Brake Assist
Emergency brake assist detects when you
brake heavily by measuring the rate at which
you press the brake pedal. It provides
maximum braking efficiency as long as you
press the pedal. Emergency brake assist
can reduce stopping distances in critical
situations.Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking. This lamp momentarily illuminates
when you switch the ignition on. If
the light does not illuminate during
start up, remains on or flashes, the anti-lock
braking system may be disabled. Have the
system checked by an authorized dealer. If
the anti-lock brake system is disabled,
normal braking is still effective.
See
Warning Lamps and Indicators (page
111).
Note: Indicators vary depending on region. This lamp also illuminates
momentarily when you switch the
ignition on to confirm the lamp is
functional. If it does not illuminate
when you switch the ignition on,
or begins to flash at any time, have
the system checked by an authorized dealer.
If the brake warning lamp illuminates with
the parking brake released, have the system
checked immediately.

TRAILER SWAY CONTROL WARNING: Turning off trailer sway
control increases the risk of loss of vehicle
control, serious injury or death. Ford does
not recommend disabling this feature
except in situations where speed reduction
may be detrimental (such as hill climbing),
the driver has significant trailer towing
experience, and can control trailer sway
and maintain safe operation.
Note: This feature does not prevent trailer
sway, but reduces it once it begins.
Note: This feature cannot stop all trailers
from swaying.
Note: In some cases, if vehicle speed is too
high, the system may activate multiple times,
gradually reducing vehicle speed. This feature applies your vehicle brakes at
individual wheels and, if necessary, reduces
engine power. If the trailer begins to sway,
the stability control light flashes and the
message TRAILER SWAY REDUCE SPEED
appears in the information display. The first
thing to do is slow your vehicle down, then
pull safely to the side of the road and check
for proper tongue load and trailer load
distribution.
See Load Carrying (page 270).
RECOMMENDED TOWING
WEIGHTS
Note: Do not exceed the trailer weight
for your vehicle configuration listed in
the chart below. Note:
Make sure to take into
consideration trailer frontal area. Do not
exceed 20 ft² (1.86 m²) for vehicles
without towing package, or 30 ft² (2.79
m²) for vehicles with towing package.
Note: For high altitude operation,
reduce the gross combined weight by
2% per
1,000 ft (300 m) starting at the
1,000 ft (300 m) elevation point.
Note: Certain states require electric
trailer brakes for trailers over a specified
weight. Be sure to check state
regulations for this specified weight. The
maximum trailer weights listed may be
limited to this specified weight, as the
vehicle ’s electrical system may not
include the wiring connector needed to
activate electric trailer brakes.
279
Nautilus (CD9) Canada/United States of America, enUSA, Edition date: 201907, First-Printing Towing

Trailer lamps are required on most towed
vehicles. Make sure all running lights, brake
lights, turn signals and hazard lights are
working.
Before Towing a Trailer
Practice turning, stopping and backing up to
get the feel of your vehicle-trailer
combination before starting on a trip. When
turning, make wider turns so the trailer
wheels clear curbs and other obstacles.
When Towing a Trailer
•
Do not drive faster than 70 mph
(113 km/h) during the first 500 mi
(800 km).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly after
you have traveled
50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
transmission in park (P) to aid engine and
transmission cooling and to help A/C
performance. •
Turn off the speed control with heavy
loads or in hilly terrain. The speed control
may turn off automatically when you are
towing on long, steep grades.
• Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.
• If your transmission is equipped with a
Grade Assist or Tow/Haul feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and transmission
cooling.
• Allow more distance for stopping with a
trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a grade. However, if
you must park on a grade:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the transmission in park (P). 4. Place wheel chocks in front and back of
the trailer wheels. Chocks are not
included with your vehicle.
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer
before
backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after
removing the trailer from the water.
When backing down a ramp during boat
launching or retrieval:
• Do not allow the static water level to rise
above the bottom edge of the rear
bumper.
• Do not allow waves to break higher than
6 in (15 cm)
above the bottom edge of
the rear bumper.
Exceeding these limits may allow water to
enter vehicle components:
• Causing internal damage to the
components.
• Affecting driveability, emissions, and
reliability.
282
Nautilus (CD9) Canada/United States of America, enUSA, Edition date: 201907, First-Printing Towing

BREAKING-IN
You need to break in new tires for
approximately 300 mi (480 km). During this
time, your vehicle may exhibit some unusual
driving characteristics.
Avoid driving too fast during the first 1,000 mi
(1,600 km)
. Vary your speed frequently and
change up through the gears early. Do not
labor the engine.
Do not tow during the first
1,000 mi
(1,600 km).
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
109).
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 329).
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.
285
Nautilus (CD9) Canada/United States of America, enUSA, Edition date: 201907, First-Printing Driving Hints

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.
• Do not rest your foot on the brake pedal
while driving.
• Avoid carrying unnecessary weight.
• Avoid adding particular accessories to
your vehicle (e.g. bug deflectors,
rollbars/light bars, running boards, ski
racks).
• Avoid driving with the wheels out of
alignment. COLD WEATHER PRECAUTIONS
The functional operation of some
components and systems can be affected at
temperatures below -13°F (-25°C).
DRIVING THROUGH WATER WARNING:
Do not drive through
flowing or deep water as you may lose
control of your vehicle.
Note: Driving through standing water can
cause vehicle damage.
Note: Engine damage can occur if water
enters the air filter.
Before driving through standing water, check
the depth. Never drive through water that is
higher than the bottom of the front rocker
area of your vehicle. When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction may
be limited. After driving through water and
as soon as it is safe to do so:
•
Lightly press the brake pedal to dry the
brakes and to check that they work.
• Check that the horn works.
• Check that the exterior lights work.
• Turn the steering wheel to check that the
steering power assist works.
