Service LINCOLN MKZ 2016 Workshop Manual

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.

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.
Reinstall the air filter assembly. After the fluid
level has been checked and adjusted as
necessary, do the following:
1. Shut the engine off.
2. Loosen the clamp holding the air filterassembly to the rubber hose.
3. Rotate the air filter assembly 90 degrees clockwise without disconnecting the
sensor.
4. Seat the air filter assembly back into the grommets by pushing down on the air
filter assembly.
5. Tighten the clamp.
6. Install and tighten two bolts that attach air filter assembly to the front of the
vehicle.
7. Install the bolt cover (if equipped).
8. Reinstall the harness retaining clip into the front of the air filter assembly.BRAKE FLUID CHECK
Fluid levels between the MIN and MAX lines
are within the normal operating range; there
is no need to add fluid. If the fluid levels are
outside of the normal operating range, the
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.

CHANGING THE 12V BATTERY
WARNINGS
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 proper ventilation.
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.
WARNINGS
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.
Your vehicle is equipped with a Motorcraft®
maintenance-free battery which normally
does not require additional water during its
life of service.
Note: If your battery has a cover or shield,
make sure it is reinstalled after the battery
has been cleaned or replaced.
Note: See an authorized dealer for low
voltage battery access, testing, or
replacement. When a low voltage battery replacement is
necessary, see an authorized dealer to
replace the low voltage battery with a Ford
recommended replacement low voltage
battery that matches the electrical
requirements of the vehicle
To ensure proper operation of the battery
management system (BMS), do not allow a
technician to connect any electrical device
ground connection directly to the low voltage
battery negative post. A connection at the
low voltage battery negative post can cause
inaccurate measurements of the battery
condition and potential incorrect system
operation.
Note:
If a person adds electrical or electronic
accessories or components to the vehicle,
the accessories or components may
adversely affect the low voltage battery
performance and durability and may also
affect the performance of other electrical
systems in the vehicle.
For longer, trouble-free operation, keep the
top of the battery clean and dry. Also, make
certain the battery cables are always tightly
fastened to the battery terminals.

Horizontal Aim Adjustment
Horizontal aim is not required for this vehicle
and is not adjustable.
CHANGING A BULB
Lamp Assembly Condensation
Exterior lamps are vented to accommodate
normal changes in pressure. Condensation
can be a natural by-product of this design.
When moist air enters the lamp assembly
through the vents, there is a possibility that
condensation can occur when the
temperature is cold. When normalcondensation occurs, a thin film of mist can
form on the interior of the lens. The thin mist
eventually clears and exits through the vents
during normal operation. Clearing time may
take as long as 48 hours under dry weather
conditions.
Examples of acceptable condensation are:
• Presence of thin mist (no streaks, drip
marks or droplets).
• Fine mist covers less than 50% of the lens.
Examples of unacceptable moisture (usually
caused by a lamp water leak) are:
• Water puddle inside the lamp.
• Large water droplets, drip marks or streaks present on the interior of the lens. Take your vehicle to a dealer for service if
any of the above conditions of unacceptable
moisture are present.
Replacing Bulbs
For replacing bulbs, see your authorized
dealer.
BULB SPECIFICATION CHART
Replacement bulbs are specified in the chart
below. Headlamp bulbs must be marked with
an authorized “D.O.T.” for North America to
make sure they have the proper lamp
performance, light brightness, light pattern,
and safe visibility. The correct bulbs will not
damage the lamp assembly or void the lamp
assembly warranty and will provide quality
bulb illumination time.

Tire Quality Grades apply to new
pneumatic passenger car tires. The
Quality grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example: Treadwear 200
Traction AA Temperature A.
These Tire Quality Grades are
determined by standards that the United
States Department of Transportation has
set.
Tire Quality Grades apply to new
pneumatic passenger car tires. They do
not apply to deep tread, winter-type
snow tires, space-saver or temporary
use spare tires, light truck or LT type
tires, tires with nominal rim diameters of
10 to 12 inches or limited production tires
as defined in Title 49 Code of Federal
Regulations Part 575.104 (c)(2).
U.S. Department of Transportation Tire
quality grades: The U.S. Department of
Transportation requires Ford Motor
Company to give you the following
information about tire grades exactly as
the government has written it.Treadwear
The treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course.
For example, a tire graded 150 would
wear 1 ½ times as well on the
government course as a tire graded 100.
The relative performance of tires
depends upon the actual conditions of
their use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices, and differences in road
characteristics and climate.
Traction AA A B C
WARNING
The traction grade assigned to this
tire is based on straight-ahead
braking traction tests, and does not
include acceleration, cornering,
hydroplaning or peak traction
characteristics.
The traction grades, from highest to
lowest are AA, A, B, and C. The grades
represent the tire’s ability to stop on wet
pavement as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction
performance.
Temperature A B C
WARNING
The temperature grade for this tire
is established for a tire that is
properly inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either separately or
in combination, can cause heat buildup
and possible tire failure.
The temperature grades are A (the
highest), B and C, representing the tire’s
resistance to the generation of heat and
its ability to dissipate heat when tested
under controlled conditions on a
specified indoor laboratory test wheel.
Sustained high temperature can cause

Inflating Your Tires
Safe operation of your vehicle requires
that your tires are properly inflated.
Remember that a tire can lose up to half
of its air pressure without appearing flat.
Every day before you drive, check your
tires. If one looks lower than the others,
use a tire gauge to check pressure of all
tires and adjust if required.
At least once a month and before long
trips, inspect each tire and check the tire
pressure with a tire gauge (including
spare, if equipped). Inflate all tires to the
inflation pressure recommended by Ford
Motor Company.
