engine overheat LINCOLN MKT 2018 Owners Manual

If you cannot move the gearshift lever out of
park (P) position with the ignition in the on
position and the brake pedal pressed, a
malfunction may have occurred. It is possible
that a fuse has blown or your vehicle
’s brake
lamps are not operating properly. See Fuse
Specification Chart (page 267).
If the fuse is not blown and the brake lamps
are working properly, the following
procedure will allow you to move the
gearshift lever from park (P):
1. Apply the parking brake, turn the ignition
off and remove the key. 2. Remove the access plug on the side of
the center console.
3. Apply the brake pedal. Using a suitable tool (for example, a screwdriver), push
the brake-shift interlock override lever
forward while pulling the gearshift lever
out of park (P) and into neutral (N).
4. Install the access plug on side of the center console.
5. Apply the brake pedal, start the vehicle, and release the parking brake. Automatic Transmission Adaptive
Learning
This feature may increase durability and
provide consistent shift feel over the life of
your vehicle. A new vehicle or transmission
may have firm shifts, soft shifts or both. This
operation is considered normal and does not
affect function or durability of the
transmission. Over time, the adaptive
learning process fully updates transmission
operation.
If Your Vehicle Gets Stuck In Mud or
Snow
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 minute or damage to the transmission and
tires may occur, or the engine may overheat.
If your vehicle gets stuck in mud or snow,
you may 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.

USING ALL-WHEEL DRIVE
All-wheel drive uses all four wheels to power
the vehicle. This increases traction, enabling
you to drive over terrain and road conditions
that a conventional two-wheel drive vehicle
cannot. The AWD system is active all the time
and requires no input from the operator.
Note:
Your AWD vehicle is not intended for
off-road use. The AWD feature gives your
vehicle some limited off-road capabilities in
which driving surfaces are relatively level,
obstruction-free and otherwise similar to
normal on-road driving conditions. Operating
your vehicle under other than those
conditions could subject the vehicle to
excessive stress which might result in
damage which is not covered under your
warranty.
Note: When an AWD system fault is present,
the warning Check AWD displays in the
information display. The AWD system is not
functioning correctly and defaults to
front-wheel drive. When this warning
displays, have your vehicle serviced at an
authorized dealer. Note:
The
AWD OFF message may also
appear in the information display if the AWD
system overheats and defaults to front-wheel
drive. This may occur if the vehicle is
operated in extreme conditions with
excessive wheel slip, such as deep sand.
To resume normal AWD function as soon as
possible, stop the vehicle in a safe location
and stop the engine for at least 10 minutes.
After the engine has been restarted and the
AWD system has adequately cooled, the
AWD OFF
message will turn off and normal
AWD function returns. If the engine is not
stopped, the
AWD OFF message turns off
when the system cools and normal AWD
function returns.

Operating AWD Vehicles With
Mismatched Tires
WARNINGS
Only use replacement tires and wheels
that are the same size, load index,
speed rating and type (such as P-metric
versus LT-metric or all-season versus
all-terrain) as those originally provided by
Ford. The recommended tire and wheel size
may be found on either the Safety
Compliance Certification Label (affixed to
either the door hinge pillar, door-latch post,
or the door edge that meets the door-latch
post, next to the driver's seating position), or
the Tire Label which is located on the B-Pillar
or edge of the driver's door. If this
information is not found on these labels, then
you should contact your authorized dealer
as soon as possible. Use of any tire or wheel
not recommended by Ford can affect the
safety and performance of your vehicle,
which could result in an increased risk of loss
of vehicle control, vehicle rollover, personal
injury and death. WARNINGS
The use of non-recommended tires and
wheels could cause steering,
suspension, axle, transfer case or power
transfer unit failure. If you have questions
regarding tire replacement, contact your
authorized dealer as soon as possible. Major dissimilar tire sizes between the front
and rear axles (for example, 17 inch low
profile tires on the front axle and 22 inch high
profile tires on the rear axle) could cause the
AWD system to stop functioning and default
to front-wheel drive or damage the AWD
system. However, the AWD system is
capable of tolerating any combination of new
and worn tires of the same original tire size.
For example, using 3 worn tread tires and 1
new tread tire all of the same original tire
size, can be tolerated by the AWD system.
Driving In Special Conditions With All-
Wheel Drive (AWD)
AWD vehicles are equipped for driving on
sand, snow, mud and rough roads and have
operating characteristics that are somewhat
different from conventional vehicles, both on
and off the highway.
When driving at slow speeds in deep sand
under high outside temperatures, use a low
gear when possible. Lower gear operation
will maximize the engine and transmission
cooling capability.
Under severe operating conditions, the A/C
may cycle on and off to protect overheating
of the engine.
Basic operating principles in special
conditions
•
Drive slower in strong crosswinds which
can affect the normal steering
characteristics of your vehicle.
• Be extremely careful when driving on
pavement made slippery by loose sand,
water, gravel, snow or ice.
185
MKT (TP4) , enUSA, Edition date: 201703, First Printing All-Wheel Drive (If Equipped)

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 while 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 WARNINGS
Always fully apply the parking brake.
Make sure you shift into park (P) for
vehicles with an automatic transmission.
Switch the ignition off and remove the key
whenever you leave your vehicle. 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. 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 it
may be rocked 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 is equipped with
AdvanceTrac® with Roll Stability Control™, it
may be beneficial to disengage the
AdvanceTrac® with Roll Stability Control™
system while 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 (that is, turn the steering
wheel only as rapidly and as far as
required to avoid the emergency).
Excessive steering will result in less
vehicle control, not more. Additionally,
smooth variations of the accelerator
and/or brake pedal pressure should be
utilized if changes in vehicle speed are
called for. Avoid abrupt steering,
186
MKT (TP4) , enUSA, Edition date: 201703, First Printing All-Wheel Drive
(If Equipped)

acceleration or braking which could result
in an increased risk of loss of vehicle
control, vehicle rollover and/or personal
injury. Use all available road surface to
return the vehicle to a safe direction of
travel.
• In the event of an emergency stop, avoid
skidding the tires and do not attempt any
sharp steering wheel movements.
• If the vehicle goes from one type of
surface to another (that is, from concrete
to gravel) there will be a change in the
way the vehicle responds to a maneuver
(steering, acceleration or braking). Again,
avoid these abrupt inputs.
Sand
Most of the time traction control improves
tire traction by managing wheel slip through
Brake, Engine, and AWD calibrations.
However, during low speed driving, disabling
traction control in deep sand can help keep
the wheels moving to maintain vehicle
momentum. When driving over sand, try to keep all four
wheels on the most solid area of the trail.
Avoid reducing the tire pressures but shift
to a lower gear and drive steadily through
the terrain. Apply the accelerator slowly and
avoid spinning the wheels.
Do not drive your vehicle in deep sand for
an extended period of time. This could
cause the AWD system to overheat and
default to front-wheel drive. If this occurs,
an AWD OFF message displays in the
information display. To resume normal AWD
function as soon as possible, stop the vehicle
in a safe location and stop the engine for at
least 10 minutes. After the engine has been
restarted and the AWD system has
adequately cooled, the AWD OFF message
turns off and normal AWD function returns.
In the event the engine is not stopped, the
AWD OFF
message turns off when the
system cools and normal AWD function
returns.
When driving at slow speeds in deep sand
under high outside temperatures, use L (Low)
gear when possible. L (Low) gear operation
will maximize the engine and transmission
cooling capability. Under severe operating conditions, the A/C
may cycle on and off to protect overheating
of the engine.
Avoid excessive speed because vehicle
momentum can work against you and cause
the vehicle to become stuck to the point that
assistance may be required from another
vehicle. Remember, you may be able to back
out the way you came if you proceed with
caution.
Mud and Water
If you must drive through high water, drive
slowly. Traction or brake capability may be
limited.
When driving through water, determine the
depth; avoid water higher than the bottom
of the wheel rims (for cars) or the bottom of
the hubs (for trucks) (if possible) and proceed
slowly. If the ignition system gets wet, the
vehicle may stall.

When you override the system, the
green indicator light illuminates
and the vehicle image does not
appear in the information display.
The system resumes operation when you
release the accelerator pedal. The vehicle
speed decreases to the set speed, or a lower
speed if following a slower vehicle.
Changing the Set Speed
• Press SET+ or SET- to change the set
speed in small increments.
• Press the accelerator or brake pedal until
you reach the desired speed. Press SET+
or
SET-.
• Press and hold
SET+ or SET- to change
the set speed in large increments.
Release the control when you reach the
desired speed.
The system may apply the brakes to slow
the vehicle to the new set speed. The set
speed displays continuously in the
information display when the system is
active. Canceling the Set Speed
Press
CNCL or tap the brake pedal. The set
speed does not erase.
Resuming the Set Speed
Note: Only use resume if you are aware of
the set speed and intend to return to it.
Press
RES. Your vehicle speed returns to
the previously set speed and gap setting.
The set speed displays continuously in the
information display when the system is
active.
Automatic Cancellation
Note: If the engine speed drops too low, an
audible warning sounds and a message
appears in the information display.
Automatic braking releases.
The system does not operate below
12 mph
(20 km/h).
Automatic cancellation can also occur if:
• The tires lose traction.
• The engine speed is too low.
• You apply the parking brake. Hilly Condition Usage
Note:
An audible alarm sounds and the
system shuts down if it applies brakes for an
extended period of time. This allows the
brakes to cool. The system functions
normally again after the brakes cool.
Select a lower gear when the system is
active in situations such as prolonged
downhill driving on steep grades, for
example in mountainous areas. The system
needs additional engine braking in these
situations to reduce the load on the vehicle ’s
regular brake system to prevent it from
overheating.
Switching Adaptive Cruise Control Off
Note: You erase the set speed and gap
setting when you switch the system off.
Press
OFF when the system is in standby
mode, or switch the ignition off.

Trailer Brake Controller Connector (If
Equipped)
The connector is located under the
instrument panel above the brake pedal. Trailer Lamps
WARNING
Never connect any trailer lamp wiring
to the vehicle's tail lamp wiring; this
may damage the electrical system resulting
in fire. Contact your authorized dealer as
soon as possible for assistance in proper
trailer tow wiring installation. Additional
electrical equipment may be required. 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 495 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
gearshift 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.

Maintain coolant concentration within 48%
to 50%, which equates to a freeze point
between -30°F (-34°C) and -34°F (-37°C).
Coolant concentration should be checked
using a refractometer. We do not recommend
the use of hydrometers or coolant test strips
for measuring coolant concentration.
Adding Coolant
WARNING
Never remove the coolant reservoir
cap when the engine is running or hot.
Note:
Automotive fluids are not
interchangeable. Take care not to put
engine coolant in the windshield washer fluid
reservoir or windshield washer fluid in the
engine coolant reservoir.
Note: Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the engine
cooling or heating systems. Resulting
component damage may not be covered by
the vehicle Warranty. It is very important to use prediluted coolant
approved to the correct specification in order
to avoid plugging the small passageways in
the engine cooling system. See Capacities
and Specifications (page 350). Do not mix
different colors or types of coolant in your
vehicle. Mixing of engine coolants or using
an incorrect coolant may harm the engine or
cooling system components and may not be
covered by the vehicle Warranty.
Note: If prediluted coolant is not available,
use the approved concentrated coolant
diluting it to 50/50 with distilled water.
See
Capacities and Specifications (page 350).
Using water that has not been deionised
may contribute to deposit formation,
corrosion and plugging of the small cooling
system passageways.
Note: Coolants marketed for all makes and
models may not be approved to Ford
specifications and may cause damage to
the cooling system. Resulting component
damage may not be covered by the vehicle
Warranty. If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
To top up the coolant level do the following:
1. Unscrew the cap slowly. Any pressure
escapes as you unscrew the cap.
2. Add prediluted coolant approved to the correct specification. See Capacities and
Specifications
(page 350).
3. Add enough prediluted coolant to reach
the correct level.
4. Replace the coolant reservoir cap, turn it clockwise until you feel a strong
resistance.
5. Check the coolant level in the coolant reservoir the next few times you drive
your vehicle. If necessary, add enough
prediluted engine coolant to bring the
coolant level to the correct level.
If you have to add more than
1.1 qt (1 L) of
engine coolant per month, have your vehicle
checked as soon as possible. Operating an
engine with a low level of coolant can result
in engine overheating and possible engine
damage.
294
MKT (TP4) , enUSA, Edition date: 201703, First Printing Maintenance

Note:
During normal vehicle operation, the
coolant may change color from orange to
pink or light red. As long as the coolant is
clear and uncontaminated, this color change
does not indicate the coolant has degraded
nor does it require the coolant to be drained,
the system to be flushed, or the coolant to
be replaced.
In case of emergency, you can add a large
amount of water without engine coolant in
order to reach a vehicle service location. In
this instance, qualified personnel:
1. Must drain the cooling system.
2. Chemically clean the coolant system with
Motorcraft Premium Cooling System
Flush.
3. Refill with engine coolant as soon as possible.
Water alone, without engine coolant, can
cause engine damage from corrosion,
overheating or freezing.
Do not use the following as a coolant
substitute:
• Alcohol.
• Methanol. •
Brine.
• Any coolant mixed with alcohol or
methanol antifreeze.
Alcohol and other liquids can cause engine
damage from overheating or freezing.
Do not add extra inhibitors or additives to
the coolant. These can be harmful and
compromise the corrosion protection of the
coolant.
Recycled Coolant
We do not recommend the use of recycled
coolant as an approved recycling process is
not yet available.
Dispose of used engine coolant in an
appropriate manner. Follow your
community's regulations and standards for
recycling and disposing of automotive fluids. Severe Climates
If you drive in extremely cold climates:
•
It may be necessary to increase the
coolant concentration above 50%.
• A coolant concentration of 60% provides
improved freeze point protection.
Coolant concentrations above 60%
decrease the overheat protection
characteristics of the coolant and may
cause engine damage.
If you drive in extremely hot climates:
• You can decrease the coolant
concentration to 40%.
• Coolant concentrations below 40%
decrease the freeze and corrosion
protection characteristics of the coolant
and may cause engine damage.
Vehicles driven year-round in non-extreme
climates should use prediluted coolant for
optimum cooling system and engine
protection.
295
MKT (TP4) , enUSA, Edition date: 201703, First Printing Maintenance

Coolant Change
At specific mileage intervals, as listed in the
scheduled maintenance information, the
coolant should be changed. Add prediluted
coolant approved to the correct specification.
See Capacities and Specifications (page
350).
Fail-Safe Cooling
Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient temperature,
vehicle load and terrain.
How Fail-Safe Cooling Works If the engine begins to overheat,
the coolant temperature gauge
moves toward the red zone:
A warning lamp illuminates and a
message may appear 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.
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 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 when the engine is running or hot.
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:
