ENGINE OIL CHECK
To check the engine oil level consistently
and accurately, do the following:
1. Make sure the parking brake is on. Make
sure the transmission is in park (P) or
neutral (N). 2. Run the engine until it reaches normal
operating temperature.
3. Make sure that your vehicle is on level ground.
4. Switch the engine off and wait 15 minutes
for the oil to drain into the oil pan.
Checking the engine oil level too soon
after you switch the engine off may result
in an inaccurate reading.
5. Open the hood. See Opening and
Closing the Hood (page 322).
6. Remove the dipstick and wipe it with a clean, lint-free cloth.
See Under Hood
Overview (page 324).
7. Reinstall the dipstick and remove it again
to check the oil level. See Under Hood
Overview
(page 324).
8. Make sure that the oil level is between the maximum and minimum marks. If the
oil level is at the minimum mark, add oil
immediately.
See Capacities and
Specifications (page 391).
9. If the oil level is correct, replace the dipstick and make sure it is fully seated. Note:
Do not remove the dipstick when the
engine is running.
Note: If the oil level is between the
maximum and minimum marks, the oil level
is acceptable. Do not add oil.
Note: The oil consumption of new engines
reaches its normal level after approximately
3,000 mi (5,000 km)
.
Adding Engine Oil WARNING:
Do not remove the filler
cap when the engine is running.

If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating cylinder
operation. Each disabled cylinder acts as an
air pump and cools the engine.
When this occurs, your vehicle still operates,
however:
•
Engine power is limited.
• The air conditioning system turns off.
Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you can
re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage. When Fail-Safe Mode Is Activated WARNING: Fail-safe mode is for use
during emergencies only. Operate your
vehicle in fail-safe mode only as long as
necessary to bring your vehicle to rest in
a safe location and seek immediate repairs.
When in fail-safe mode, your vehicle will
have limited power, will not be able to
maintain high-speed operation, and may
completely shut down without warning,
potentially losing engine power, power
steering assist, and power brake assist,
which may increase the possibility of a
crash resulting in serious injury. WARNING: Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap with
a thick cloth to prevent the possibility of
scalding and slowly remove the cap.
Failure to follow this instruction could result
in personal injury. Your vehicle has limited engine power when
in the fail-safe mode, drive your vehicle with
caution. Your vehicle does not maintain
high-speed operation and the engine may
operate poorly.
Remember that the engine is capable of
automatically shutting down to prevent
engine damage. In this situation:
1. Pull off the road as soon as safely
possible and switch the engine off.
2. If you are a member of a roadside assistance program, we recommend that
you contact your roadside assistance
service provider.
3. If this is not possible, wait a short period
for the engine to cool.
4. Check the coolant level. If the coolant level is at or below the minimum mark,
add prediluted coolant immediately.
5. When the engine temperature cools, you
can re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage.
Note: Driving your vehicle without repair
increases the chance of engine damage.

Engine Coolant Temperature
Management (If Equipped)
WARNING:
To reduce the risk of
crash and injury, be prepared that the
vehicle speed may reduce and the vehicle
may not be able to accelerate with full
power until the coolant temperature
reduces.
If you tow a trailer with your vehicle, the
engine may temporarily reach a higher
temperature during severe operating
conditions, for example ascending a long or
steep grade in high ambient temperatures.
At this time, you may notice the coolant
temperature gauge moves toward the red
zone and a message may appear in the
information display. You may notice a reduction in vehicle speed
caused by reduced engine power in order
to manage the engine coolant temperature.
Your vehicle may enter this mode if certain
high-temperature and high-load conditions
take place. The amount of speed reduction
depends on vehicle loading, grade and
ambient temperature. If this occurs, there is
no need to stop your vehicle. You can
continue to drive.
The air conditioning may automatically turn
on and off during severe operating
conditions to protect the engine from
overheating. When the coolant temperature
decreases to the normal operating
temperature, the air conditioning turns on.
If the coolant temperature gauge moves fully
into the red zone, or if the coolant
temperature warning or service engine soon
messages appear in your information display,
do the following:
1.
Stop your vehicle as soon as it is safe to
do so. Fully apply the parking brake, shift
into park (P) or neutral (N). 2. Leave the engine running until the
coolant temperature gauge needle
returns to the normal position. If the
temperature does not drop after several
minutes, follow the remaining steps.
3. Switch the engine off and wait for it to cool. Check the coolant level.
4. If the coolant level is at or below the minimum mark, add prediluted coolant
immediately.
5. If the coolant level is normal, restart the engine and continue.
AUTOMATIC TRANSMISSION
FLUID CHECK
The automatic transmission does not have
a transmission fluid dipstick.
Have an authorized dealer check and change
the transmission fluid at the correct service
interval. See Scheduled Maintenance (page
495
). Your transmission does not consume
fluid. However, if the transmission slips, shifts
slowly or if you notice a sign of leaking fluid,
contact an authorized dealer.
333
Nautilus (CD9) Canada/United States of America, enUSA, Edition date: 201907, First-Printing Maintenance

Do not use supplemental transmission fluid
additives, treatments or cleaning agents. The
use of these materials may affect
transmission operation and result in damage
to internal transmission components.
BRAKE FLUID CHECK
WARNING: Do not use any fluid other
than the recommended brake fluid as this
will reduce brake efficiency. Use of
incorrect fluid could result in the loss of
vehicle control, serious personal injury or
death. WARNING: Only use brake fluid from
a sealed container. Contamination with dirt,
water, petroleum products or other
materials may result in brake system
damage or failure. Failure to adhere to this
warning could result in the loss of vehicle
control, serious personal injury or death. WARNING:
Do not allow the fluid to
touch your skin or eyes. If this happens,
rinse the affected areas immediately with
plenty of water and contact your physician. WARNING:
The brake system could
be affected if the brake fluid level is below
the
MIN mark or above the MAX mark on
the brake fluid reservoir. 1. Park your vehicle on a level surface.
2. Look at the brake fluid reservoir to see
where the brake fluid level is relative to
the
MIN and the MAX marks on the
reservoir.
Note: If the brake fluid level is between the
MIN
and the MAX marks on the reservoir, it
is acceptable.
334
Nautilus (CD9) Canada/United States of America, enUSA, Edition date: 201907, First-Printing MaintenanceE170684

Note:
If the brake fluid level is below the MIN
mark or above the MAX mark, have your
vehicle checked as soon as possible.
Note: To avoid fluid contamination, the
reservoir cap must remain in place and fully
tight, unless you are adding fluid.
Only use fluid that meets our specifications.
See
Capacities and Specifications (page
385).
Brake Fluid Service Interval
Brake fluid absorbs water over time which
degrades the effectiveness of the brake fluid.
Change the brake fluid at the specified
intervals to prevent degraded braking
performance.
For detailed interval information, see
Scheduled Maintenance in your Owner's
Manual or your local maintenance guide. WASHER FLUID CHECK WARNING:
If you operate your
vehicle in temperatures below 41.0°F (5°C),
use washer fluid with antifreeze protection.
Failure to use washer fluid with antifreeze
protection in cold weather could result in
impaired windshield vision and increase
the risk of injury or accident.
Note: The front and rear washer systems
are supplied from the same reservoir.
Add fluid to fill the reservoir if the level is low.
Only use a washer fluid that meets our
specifications.
See Capacities and
Specifications (page 385).
State or local regulations on volatile organic
compounds may restrict the use of methanol,
a common windshield washer antifreeze
additive. Washer fluids containing
non-methanol antifreeze agents should be
used only if they provide cold weather
protection without damaging the vehicle ’s
paint finish, wiper blades or washer system. FUEL FILTER
Your vehicle is equipped with a lifetime fuel
filter that is integrated with the fuel tank.
Regular maintenance or replacement is not
needed.
CHANGING THE 12V BATTERY
WARNING:
Batteries normally
produce explosive gases which can cause
personal injury. Therefore, do not allow
flames, sparks or lighted substances to
come near the battery. When working near
the battery, always shield your face and
protect your eyes. Always provide correct
ventilation. WARNING:
When lifting a
plastic-cased battery, excessive pressure
on the end walls could cause acid to flow
through the vent caps, resulting in personal
injury and damage to the vehicle or battery.
Lift the battery with a battery carrier or with
your hands on opposite corners.
335
Nautilus (CD9) Canada/United States of America, enUSA, Edition date: 201907, First-Printing Maintenance

WARNING: Keep batteries out of
reach of children. Batteries contain sulfuric
acid. Avoid contact with skin, eyes or
clothing. Shield your eyes when working
near the battery to protect against possible
splashing of acid solution. In case of acid
contact with skin or eyes, flush immediately
with water for a minimum of 15 minutes and
get prompt medical attention. If acid is
swallowed, call a physician immediately. WARNING:
Battery posts, terminals
and related accessories contain lead and
lead compounds. Wash hands after
handling. WARNING:
For vehicles with
Auto-Start-Stop the battery requirement is
different. You must replace the battery with
one of exactly the same specification.
Your vehicle is fitted with a Motorcraft
maintenance-free battery which normally
does not require additional water. When a battery replacement is required, you
must use a recommended replacement
battery that matches the electrical
requirements of the vehicle.
Note:
If your vehicle has a battery cover,
after cleaning or replacing the battery, make
sure you reinstall it.
Note: See an authorized dealer for battery
access, testing, or replacement.
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.
If you see any corrosion 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. Because your vehicle
’s engine is
electronically-controlled by a computer,
some engine control settings are maintained
by power from the battery. Some engine
computer settings, like the idle trim and fuel
trim strategy, optimize the driveability and
performance of the engine. The clock and
radio station presets are also maintained in
memory by power from the low-voltage
battery. These settings are erased when a
technician disconnects and connects the
low-voltage battery.
To restore the settings, do the following:
Note: Until you switch the ignition to the on
position, you will receive a message in your
information display stating that your vehicle
is not in park.
1. Apply the parking brake.
2. Shift into park (P) or neutral (N).
3. Switch off all accessories.
4. Press the brake pedal and start your vehicle.

For routine cleaning, wipe the surface with
a soft, damp cloth and a mild soap and water
solution. Dry the area with a clean, soft cloth.
Note:
Test any cleaner or stain remover on
an inconspicuous area.
You should:
• Remove dust and loose dirt with a
vacuum cleaner.
• Clean and treat spills and stains as soon
as possible.
Do not use the following products as these
may damage the leather:
• Oil and petroleum or silicone-based
leather conditioners.
• Household cleaners.
• Alcohol solutions.
• Solvents or cleaners intended specifically
for rubber, vinyl and plastics. REPAIRING MINOR PAINT
DAMAGE
Authorized dealers have touch-up paint to
match your vehicle
’s color. Your vehicle color
code is printed on a sticker on the front,
left-hand side door jamb. Take your color
code to your authorized dealer to make sure
you get the correct color.
Before repairing minor paint damage, use a
cleaner such as Motorcraft Bug and Tar
Remover to remove particles such as bird
droppings, tree sap, insect deposits, tar
spots, road salt and industrial fallout.
Always read the instructions before using
cleaning products.
CLEANING THE WHEELS
Note: Do not apply a cleaning chemical to
warm or hot wheel rims and covers. Note:
Industrial-strength (heavy-duty)
cleaners, or cleaning chemicals, in
combination with brush agitation to remove
brake dust and dirt, could wear away the
clear coat finish over a period of time.
Note: Do not use hydrofluoric acid-based or
high caustic-based wheel cleaners, steel
wool, fuels or strong household detergent.
Note: If you intend to park your vehicle for
an extended period after cleaning the
wheels with a wheel cleaner, drive your
vehicle for a few minutes before doing so.
This reduces the risk of increased corrosion
of the brake discs, brake pads and linings.
Note: Some automatic car washes could
cause damage to the finish on your wheel
rims and covers.

VEHICLE STORAGE
If you plan on storing your vehicle for 30
days or more, read the following
maintenance recommendations to make sure
your vehicle stays in good operating
condition. We engineer and test all motor vehicles and
their components for reliable, regular driving.
Under various conditions, long-term storage
may lead to degraded engine performance
or failure unless you use specific precautions
to preserve engine components.
General
•
Store all vehicles in a dry, ventilated
place.
• Protect from sunlight, if possible.
• If vehicles are stored outside, they
require regular maintenance to protect
against rust and damage.
Body
• Wash your vehicle thoroughly to remove
dirt, grease, oil, tar or mud from exterior
surfaces, rear-wheel housing and the
underside of front fenders.
• Periodically wash your vehicle if it is
stored in exposed locations.
