engine LINCOLN MKZ 2016 Manual Online

If you drive in extremely hot climates:
• It may be necessary to have anauthorized dealer decrease the coolant
concentration to 40%.
• A coolant concentration of 40% provides improved overheat protection. Engine
coolant concentrations below 40%
decrease the freeze and corrosion
protection characteristics of the engine
coolant and may cause engine damage.
Vehicles driven year-round in non-extreme
climates should use prediluted engine
coolant for optimum cooling system and
engine protection.
What You Should Know About Fail-Safe
Cooling
If the engine coolant supply is depleted, this
feature allows the vehicle to be driven
temporarily before incremental component
damage is incurred. The fail-safe distance
depends on outside temperatures, vehicle
load and terrain. How Fail-Safe Cooling Works
If the engine begins to overheat, the engine
coolant temperature gauge moves to the red
(hot) area and:
A high engine temperature
message appears in the
information display.
The service engine soon indicator
appears in the information display.
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.
If this occurs, your vehicle still operates.
However:
• The engine power becomes limited.
• The air conditioning system becomes disabled.
Continued operation increases the engine
temperature and the engine completely
shuts down, causing steering and braking
effort to increase. Once the engine temperature cools, the
engine can be re-started. Take your vehicle
to an authorized dealer as soon as possible
to minimize engine damage.
When Fail-Safe Mode Is Activated
WARNINGS
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.
Never remove the coolant reservoir
cap while the engine is running or hot.
291
Maintenance

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
operates 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 safelypossible and switch off the engine.
2. Tow your vehicle to an authorized dealer.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and add if low.
5. Re-start the engine and drive your vehicle to an authorized dealer.
Note: Driving your vehicle without repair
increases the chance of engine damage.
See an authorized dealer as soon as
possible.AUTOMATIC TRANSMISSION
FLUID CHECK
6F35/HF35 transmission (If Equipped)
Note: Transmission fluid should be checked
by an authorized dealer. If required, fluid
should be added by an authorized dealer.
The automatic transmission does not have
a transmission fluid dipstick.
Refer to your scheduled maintenance
information for scheduled intervals for fluid
checks and changes. Your transmission does
not consume fluid. However, the fluid level
should be checked if the transmission is not
working properly, (For example: if the
transmission slips or shifts slowly) or if you
notice some sign of fluid leakage. See
Scheduled Maintenance (page 480).
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.
6F50/6F55 Transmission (If Equipped)
WARNINGS
The dipstick cap and surrounding
components may be hot; gloves are
recommended.
Use gloves when moving the air filter
assembly. Components will be hot.
Note: Automatic transmission fluid expands
when warmed. To obtain an accurate fluid
check, drive the vehicle until it is warmed up
(approximately 20 miles [30 kilometers]). If
your vehicle has been operated for an
extended period at high speeds, in city traffic
during hot weather or pulling a trailer, the
vehicle should be turned off until normal
operating temperatures are reached to allow
the fluid to cool before checking. Depending
on vehicle use, cooling times could take up
to 30 minutes or longer.

performance of the system could be
compromised; seek service from your
authorized dealer immediately.
WASHER FLUID CHECK
WARNING
If you operate your vehicle in
temperatures below 40°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 Ford
specifications. See Capacities and
Specifications (page 353).
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.
296
Maintenance

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.
When a battery replacement is required, the
battery should only be replaced with a Ford
recommended replacement battery that
matches the electrical requirements of the
vehicle.
Because your vehicle’s engine is
electronically-controlled by a computer,
some engine control settings are maintained
by power from the low voltage battery. Some
engine computer settings, like the idle trim
and fuel trim strategy, optimize the
driveability and performance of the engine.
Some other computer settings, like the clock
and radio station presets, are also maintained
in memory by power from the low voltage
battery. When a technician disconnects and
connects the low voltage battery, these
settings are erased.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.
Complete the following procedure in order
to restore the settings:
1. With the vehicle at a complete stop, set the parking brake.
2. Shift the transmission into P.
3. Turn off all accessories.
4. Step on the brake pedal and start the vehicle.
5. Run the engine until it reaches normal operating temperature. While the engine
is warming up, complete the following:
Reset the clock. See Windows and
Mirrors (page 95). Reset the power
windows bounce-back feature. See
Windows and Mirrors (page 95). Reset
the radio station presets. See Windows
and Mirrors (page 95).
6. Allow the engine to idle for at least one minute. If the engine turns off, step on
the accelerator to start the engine. 7. While the engine is running, step on the
brake pedal and shift the transmission to
N.
8. Allow the engine to run for at least one minute by pressing on the accelerator
pedal.
9. Drive your vehicle at least 10 miles (16 kilometers) to completely relearn the idle
and fuel trim strategy.
Note: Certain features may not operate if
the Battery Monitor System is not reset with
a scan tool following a jump start or battery
replacement. Normal electrical accessory
operation should resume after your vehicle
is left undisturbed for 8 hours.
Note: If you do not allow the engine to
relearn the idle and fuel trim strategy, the
idle quality of your vehicle may be adversely
affected until the engine computer
eventually relearns the idle trim and fuel trim
strategy.

Vehicle Care

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 washerto 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.
• 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.
Note: Do not use razor blades or other
sharp objects to clean or remove decals from
the inside of the heated rear window. The
vehicle warranty does not cover damage
caused to the heated rear window grid lines.
307
Vehicle Care

• Clean the wheels weekly usingMotorcraft Wheel and Tire Cleaner. Apply
using manufacturer's instructions.
• Use a sponge to remove heavy deposits of dirt and brake dust accumulation.
• Rinse thoroughly with a strong stream of water when you have completed the
cleaning process.
• To remove tar and grease, use Motorcraft Bug and Tar Remover.
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, ventilatedplace.
• 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 removedirt, 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.
• Touch-up exposed or primed metal to prevent rust.
• Cover chrome and stainless steel parts with a thick coat of auto wax to prevent
