service interval LINCOLN MKZ 2020 Owners Manual

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 pull off the road. You can
continue to drive your vehicle.
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. Pull off the road as soon as safely
possible and shift the transmission into
park (P). 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
6F35 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
properly working. For example, if the
transmission slips or shifts slowly or if you
notice some sign of fluid leakage.
See
Scheduled Maintenance (page 475).
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.
6F55 Transmission
(If Equipped) WARNING:
The dipstick and
surrounding components are hot. Use
gloves when moving components and
checking the transmission fluid level.
Failure to follow this warning could result
in serious personal injury.

8. Reinstall the harness retaining clip into
the front of the air filter assembly.
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.
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
365).
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 365). 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
2.0L Engines and 3.0L Engines with
FWD
Your vehicle is equipped with a lifetime fuel
filter that is integrated with the fuel tank.
Regular maintenance or replacement is not
needed.
3.0L Engines with AWD
The fuel filter on your vehicle must be
replaced at the specified service interval.
See
Scheduled Maintenance (page 475). 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.

GENERAL MAINTENANCE
INFORMATION
Why Maintain Your Vehicle?
Carefully following the maintenance
schedule helps protect against major repair
expenses resulting from neglect or
inadequate maintenance and may help to
increase the value of your vehicle when you
sell or trade it. Keep all receipts for
completed maintenance with your vehicle.
We have established regular maintenance
intervals for your vehicle based upon
rigorous testing. It is important that you have
your vehicle serviced at the proper times.
These intervals serve two purposes; one is
to maintain the reliability of your vehicle and
the second is to keep your cost of owning
your vehicle down.
It is your responsibility to have all scheduled
maintenance performed and to make sure
that the materials used meet the
specifications identified in this owner's
manual. See Capacities and Specifications
(page 365).
Failure to perform scheduled maintenance
invalidates warranty coverage on parts
affected by the lack of maintenance.
Why Maintain Your Vehicle at Your
Dealership?
Factory-Trained Technicians
Service technicians participate in extensive
factory-sponsored certification training to
help them become experts on the operation
of your vehicle. Ask your dealership about
the training and certification their technicians
have received.
Genuine Ford and Motorcraft® Replacement
Parts
Dealerships stock Ford, Motorcraft and
Ford-authorized branded re-manufactured
replacement parts. These parts meet or
exceed our specifications. Parts installed at
your dealership carry a nationwide 24-month
or unlimited mile (kilometer) parts and labor
limited warranty.
If you do not use our authorized parts they
may not meet our specifications and
depending on the part, it could affect
emissions compliance.
Convenience
Many dealerships have extended evening
and Saturday hours to make your service
visit more convenient and they offer one stop
shopping. They can perform any services
that are required on your vehicle, from
general maintenance to collision repairs.
Note:
Not all dealers have extended hours
or body shops. Please contact your dealer
for details.
Protecting Your Investment
Maintenance is an investment that pays
dividends in the form of improved reliability,
durability and resale value. To maintain the
proper performance of your vehicle and its
emission control systems, make sure you
have scheduled maintenance performed at
the designated intervals.
