2014 LINCOLN MKZ engine overheat

Changing the Set Speed
• Accelerate or brake to the desiredspeed, then press and release
SET+.
• Press and hold SET+ or SET- until the desired set speed shows on the
information display. The vehicle
speed will gradually change to the
selected speed.
• Press and release SET+ or SET-. The set speed will change in
approximately 1 mph (2 km/h)
increments.
The system may apply the brakes to
slow the vehicle to the new set speed.
The set speed will display
continuously in the information
display while the system is active.
Resuming the Set Speed
Note: Only use resume if you are
aware of the set speed and intend to
return to it.
Press and release RES. The vehicle
will return to the previously set speed.
The set speed will display
continuously in the information
display while the system is active.
Low Speed Automatic
Cancellation
The system is not functional at vehicle
speeds below 12 mph (20 km/h). An
audible alarm will sound and the
automatic braking releases if the
vehicle drops below this speed.
Hilly Condition Usage
Note: An audible alarm will sound and
the system will shut down if it is
applying brakes for an extended period
of time. This allows the brakes to cool
down. The system will function
normally again when the brakes have
cooled down.
You should select a lower gear
position 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 them from overheating.
Switching the System Off
Note: The set speed memory erases
when you switch off the system.
Press and release OFF or turn off the
ignition.
Detection Issues
The radar sensor has a limited field of
vision. It may not detect vehicles at all
or detect a vehicle later than expected
in some situations. The lead vehicle
graphic will not illuminate if the
system does not detect a vehicle in
front of you.
203
Cruise Control

If the front end of the vehicle is hit or
damaged, the radar sensing zone may
be altered causing missed or false
collision warnings. See your
authorized dealer to have your
collision warning radar checked for
proper coverage and operation.
STEERING
Electric Power Steering
WARNINGS
The electric power steering
system has diagnostic checks
that continuously monitor the system
to ensure proper operation. When a
system error is detected a steering
message will appear in the
information display.
The electric power steering
system has diagnostic checks
that continuously monitor the system
to ensure proper operation of the
electronic system. When an electronic
error is detected, a message will be
displayed in the information display.
If this happens, stop the vehicle in a
safe place, and turn off the engine.
After at least 10 seconds, reset the
system by restarting the engine, and
watch the information display for a
steering message. If a steering
message returns, or returns while
driving, take the vehicle to your dealer
to have it checked.
WARNINGS
Obtain immediate service if a
system error is detected. You
may not notice any difference in the
feel of your steering, but a serious
condition may exist. Failure to do so
may result in loss of steering control.
Your vehicle is equipped with an
electric power-assisted steering
system. There is no fluid reservoir to
check or fill.
If your vehicle loses electrical power
while you are driving (or if the ignition
is turned off), you can steer the
vehicle manually, but it takes more
effort. Extreme continuous steering
may increase the effort it takes for you
to steer. This occurs to prevent
internal overheating and permanent
damage to your steering system. If this
should occur, you will neither lose the
ability to steer the vehicle manually
nor will it cause permanent damage.
Typical steering and driving
maneuvers will allow the system to
cool and steering assist will return to
normal.
Steering Tips
If the steering wanders or pulls, check
for:
• an improperly inflated tire
• uneven tire wear
• loose or worn suspension components
• loose or worn steering components
• improper vehicle alignment

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 500
miles (800 kilometers).
• Do not make full-throttle starts.
• Check your hitch, electrical connections and trailer wheel lug
nuts thoroughly after you have
traveled 50 miles (80 kilometers).
• When stopped in congested or heavy traffic during hot weather,
place the gearshift in position 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.
• If your transmission is equipped with a Grade Assist or Tow/Haul
feature, use this feature when
towing. This provides engine
braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.
• Allow more distance for stopping with a trailer attached. Anticipate
stops and brake gradually.
• Avoid parking on a grade. However, if you must park on a grade:
• Turn the steering wheel to pointyour vehicle tires away from
traffic flow.
• Set your vehicle parking brake.
• Place the automatic transmission in position P.
• Place wheel chocks in front and back of the trailer wheels.
(Chocks not included with
vehicle.)
Launching or Retrieving a Boat
or Personal Watercraft (PWC)
Note: Disconnect the wiring to the
trailer before backing the trailer into
the water.

Towing

WARNINGS
Do not put engine coolant in the
windshield washer fluid
container. If sprayed on the
windshield, engine coolant could
make it difficult to see through the
windshield.
To reduce the risk of personal
injury, make sure the engine is
cool before unscrewing the coolant
pressure relief cap. The cooling
system is under pressure; steam and
hot liquid can come out forcefully
when the cap is loosened slightly.
Do not add coolant further than
the MAX mark.
Note: Do not use stop leak pellets,
cooling system sealants, or additives
as they can cause damage to the
engine cooling or heating systems. This
damage would not be covered under
your vehicle’s warranty.
Note: During normal vehicle operation,
the engine coolant may change color
from orange to pink or light red. As long
as the engine coolant is clear and
uncontaminated, this color change
does not indicate the engine coolant
has degraded nor does it require the
engine coolant to be drained, the
system to be flushed, or the engine
coolant to be replaced.
• Do not mix different colors or types of coolant in your vehicle. Make
sure the correct coolant is used.
Mixing of engine coolants may
harm your engine’s cooling system.
The use of an improper coolant may harm engine and cooling
system components and may void
the warranty. Use prediluted
engine coolant meeting the Ford
specification. See Scheduled
Maintenance (page 436).
• In case of emergency, a large amount of water without engine
coolant may be added in order to
reach a vehicle service location. In
this instance, the cooling system
must be drained, chemically
cleaned with Motorcraft®
Premium Cooling System Flush,
and refilled with engine coolant as
soon as possible. Water alone
(without engine coolant) can
cause engine damage from
corrosion, overheating or freezing.
• Do not use alcohol, methanol, brine or any engine coolants mixed
with alcohol or methanol
antifreeze (coolant). 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 engine
coolant.
Unscrew the cap slowly. Any pressure
will escape as you unscrew the cap.
Add prediluted engine coolant
meeting the Ford specification. See
Scheduled Maintenance (page 436).
273
Maintenance

Whenever coolant has been added,
the coolant level in the coolant
reservoir should be checked the next
few times you drive the vehicle. If
necessary, add enough prediluted
engine coolant to bring the coolant
level to the proper level.
Recycled Engine Coolant
Ford Motor Company does not
recommend the use of recycled
engine coolant since a Ford-approved
recycling process is not yet available.
Used engine coolant should be
disposed of 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 have a Fordauthorized dealer increase the
coolant concentration above 50%.
• A coolant concentration of 60% will provide improved freeze point
protection. Engine coolant
concentrations above 60% will
decrease the overheat protection
characteristics of the engine
coolant and may cause engine
damage. If you drive in extremely hot climates:
• It may be necessary to have a Ford
authorized dealer decrease the
coolant concentration to 40%.
• A coolant concentration of 40% will provide improved overheat
protection. Engine coolant
concentrations below 40% will
decrease the corrosion/freeze
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 ambient temperatures,
vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the
engine coolant temperature gauge
will move to the red (hot) area and:
A high engine temperature
message will appear in the
information display.
The service engine soon
indicator will illuminate.

High fluid level
E158844
If the fluid level is above the MAX
range of the dipstick, remove fluid to
reach the hashmark level.
Note:Fluid level above the MAX level
may cause shift or engagement
concerns or possible damage. High
fluid levels can be caused by an
overheating condition. 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. Depending on vehicle use,
cooling times could take up to 30
minutes or longer.
Adjusting Automatic Transmission
Fluid Levels
E158845
E158846
Before adding any fluid, make sure the
correct type is used. The type of fluid
used is normally indicated on the
dipstick and also in the Technical
Specifications section in this chapter.
Note: An overfill condition of
transmission fluid may cause shift or
engagement concerns or possible
damage.
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 filter assembly 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.

General Information
WARNING
Failure to follow these guidelines
could result in an increased risk
of loss of vehicle control, injury or
death.
Note: Do not use the kit if a tire has
become severely damaged by driving
the vehicle with a tire that has
insufficient air pressure. Only punctured
areas located within the tire tread can
be sealed with the kit.
Do not attempt to repair punctures
larger than 1.4 inch (6.4 millimeters)
or damage to the tire's sidewall. The
tire may not completely seal.
Loss of air pressure may adversely
affect tire performance. For this
reason:
Note: Do not drive the vehicle above
50 mph (80 km/h).
Note: Do not drive further than 120
miles (200 kilometers). Drive only to
the closest Ford Motor Company
authorized dealer or tire repair shop to
have your tire inspected.
• Drive carefully and avoid abrupt steering maneuvers.
• Periodically monitor tire inflation pressure in the affected tire; if the
tire is losing pressure, have the
vehicle towed.
• Read the information in the Tips for Use of the Kit section to make
sure safe operation of the kit and
your vehicle.
Tips for Use of the Kit
Read the following list of tips to
ensure safe operation of the kit:
• Before operating the kit, make sureyour vehicle is safely off the road
and away from moving traffic. Turn
on the hazard lights.
• Always set the parking brake to ensure the vehicle doesn't move
unexpectedly.
• Do not remove any foreign objects, such as nails or screws, from the
tire.
• When using the kit, leave the engine running (only if the vehicle
is outdoors or in a well-ventilated
area) so the compressor doesn't
drain the vehicle's battery.
• Do not allow the compressor to operate continuously for more
than 15 minutes; this will help
prevent the compressor from
overheating.
• Never leave the kit unattended when it is operating.
• Sealant compound contains latex. Make sure that you use the
non-latex gloves provided to avoid
an allergic reaction.
• Keep the kit away from children.
• Only use the kit when the ambient temperature is between -22°F
(–30°C) and 158°F (70°C).

Wheels and Tires

Oils, Fluids and Flushing
In many cases, fluid discoloration is a
normal operating characteristic and,
by itself, does not necessarily indicate
a concern or that the fluid needs to be
changed. However, a qualified expert,
such as the factory-trained
technicians at your dealership, should
inspect discolored fluids that also
show signs of overheating or foreign
material contamination immediately.Make sure to change your vehicle’s
oils and fluids at the specified
intervals or in conjunction with a
repair. Flushing is a viable way to
change fluid for many vehicle
sub-systems during scheduled
maintenance. It is critical that systems
are flushed only with new fluid that is
the same as that required to fill and
operate the system or using a
Ford-approved flushing chemical.
Owner Checks and Services
Make sure you perform the following
basic maintenance checks and
inspections every month or at
six-month intervals.
Check every month
Engine oil level.
Function of all interior and exterior lights.
Tires (including spare) for wear and proper pressure. Windshield washer fluid level.
Check every six months
Battery connections. Clean if necessary.
Body and door drain holes for obstructions. Clean if necessary. Cooling system fluid level and coolant strength.
Door weatherstrips for wear. Lubricate if necessary.
Hinges, latches and outside locks for proper operation. Lubricate if necessary. Parking brake for proper operation.
