2017 LINCOLN MKZ overheating

If your vehicle loses electrical power while
you are driving, electric power steering
assistance is lost. The steering system still
operates and you can steer your vehicle
manually. Manually steering your vehicle
requires more effort.
Extreme continuous steering may increase
the effort required for you to steer your
vehicle. This increased effort prevents
overheating and permanent damage to the
steering system. You do not lose the ability
to steer your vehicle manually. Typical
steering and driving maneuvers allow the
system to cool and return to normal
operation.
Steering Tips
If the steering wanders or pulls, check for:
•
Correct tire pressures.
• Uneven tire wear.
• Loose or worn suspension components.
• Loose or worn steering components.
• Improper vehicle alignment. Note:
A high crown in the road or high
crosswinds may also make the steering
seem to wander or pull.
Adaptive Learning
The electronic power steering system
adaptive learning helps correct road
irregularities and improves overall handling
and steering feel. It communicates with the
brake system to help operate advanced
stability control and accident avoidance
systems. Additionally, whenever the battery
is disconnected or a new battery installed,
you must drive your vehicle a short distance
before the system relearns the strategy and
reactivates all systems.
PRE-COLLISION ASSIST WARNINGS
At all times, you are responsible for
controlling your vehicle, supervising
the system and intervening, if required.
Failure to take care may result in the loss of
control of your vehicle, serious personal
injury or death. WARNINGS
The system does not detect cyclists,
animals, pedestrians at night or
vehicles that are driving in a different
direction. Failure to take care may result in
the loss of control of your vehicle, serious
personal injury or death. The system does not operate during
hard acceleration or steering. Failure
to take care may lead to a crash or personal
injury. The system may fail or operate with
reduced function during cold and
severe weather conditions. Snow, ice, rain,
spray and fog can adversely affect the
system. Keep the front camera and radar free
of snow and ice. Failure to take care may
result in the loss of control of your vehicle,
serious personal injury or death. In situations where the vehicle camera
has limited detection capability, this
may reduce system performance. These
situations include but are not limited to direct
or low sunlight, vehicles at night without tail
lights, unconventional vehicle types,

Water alone, without prediluted 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:
• It may be necessary to decrease the
coolant concentration to 40%.
• A coolant concentration of 40% provides
improved overheat protection. 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.
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.

If you tow a trailer with your vehicle, the
engine may temporarily reach higher a
temperature during severe operating
conditions, for example ascending a long or
steep grade in high ambient temperatures.
At this time, you may notice the coolant
temperature gauge moves toward the red
zone and a message may appear in the
information display.
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. After
several minutes, if the temperature does
not drop, 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/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 495).
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.

Checking the fluid level
Low fluid level
If the fluid level is below the MIN range of
the dipstick, add fluid to reach the hash mark
level.
Note:
If the fluid level is below the MIN level,
do not drive the vehicle. An underfill
condition may cause shift or engagement
concerns or possible damage. Correct fluid level The transmission fluid should be checked at
normal operating temperature 180°F-200°F
(82°C-93°C) on a level surface. The normal
operating temperature can be reached after
approximately 20 miles (30 kilometers) of
driving.
The transmission fluid level should be
targeted within the cross-hatch area if at
normal operating temperature 180°F-200°F
(82°C-93°C).
High fluid level 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.

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 mi
(200 km). Drive only to the closest authorized
Ford 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
To ensure safe operation of the kit:
• Read all instructions and cautions fully.
• Before operating the kit, make sure your
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 does not 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 during
operation.
• Sealant compound contains latex. Those
with latex sensitivities should use
appropriate precautions 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)
. •
Only use the sealing compound before
the use-by date. The use-by date is on a
label on the sealant canister and can be
seen through the rectangular viewing
window on the bottom of the compressor.
Check the use-by date regularly and
replace the canister after four years of
non-use.
• Do not store the kit unsecured inside the
passenger compartment of the vehicle
as it may cause injury during a sudden
stop or crash. Always store the kit in its
original location.
• After sealant use, the tire pressure
monitoring system sensor and valve stem
on the wheel must be replaced by an
authorized Ford dealer.
• Operating the kit could cause an
electrical disturbance in radio, CD, and
DVD player operation. * When inflation only is required for
a tire or other objects, the selector
must be in the Air position.

Your vehicle is equipped with the Intelligent
Oil-Life Monitor system, which displays a
message in the information display at the
proper oil change interval. This interval may
be up to one year or 10000 miles (16000
kilometers).
When the oil change message appears in
the information display, it is time for an oil
change. Make sure you perform the oil
change within two weeks or 500 miles (800
kilometers) of the message appearing. Make
sure you reset the Intelligent Oil-Life Monitor
after each oil change. See Oil Change
Indicator Reset (page 302).
If your information display resets prematurely
or becomes inoperative, you should perform
the oil change interval at six months or 5000
miles (8000 kilometers) from your last oil
change. Never exceed one year or 10000
miles (16000 kilometers) between oil change
intervals. Your vehicle is very sophisticated and built
with multiple, complex, performance systems.
Every manufacturer develops these systems
using different specifications and
performance features. That is why it is
important to rely upon your dealership to
properly diagnose and repair your vehicle.
Ford Motor Company has recommended
maintenance intervals for various parts and
component systems based upon engineering
testing. Ford Motor Company relies upon this
testing to determine the most appropriate
mileage for replacement of oils and fluids to
protect your vehicle at the lowest overall cost
to you and recommends against
maintenance schedules that deviate from
the scheduled maintenance information.
We strongly recommend the use of only
genuine Ford, Motorcraft or Ford-authorized
re-manufactured replacement parts
engineered for your vehicle.Additives and Chemicals
This owner's manual and the Ford Workshop
Manual list the recommended additives and
chemicals for your vehicle. We do not
recommend using chemicals or additives not
approved by us as part of your vehicle
’s
normal maintenance. Please consult your
warranty information.
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.
