engine overheat LINCOLN MKZ 2016 User Guide

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 attempt to repair punctures larger
than 0.24 in (6 mm) 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 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 does not 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
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).
• Only use the sealing compound before the use by date. The use by date is on
the lower right hand corner of the label
located on the sealant canister (bottle).
Check the use by date regularly and
replace the canister after four years.
• 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.
• When inflating a tire or other objects, use the black air hose only. Do not use the
transparent hose which is designed for
sealant application only.
• Operating the kit could cause an electrical disturbance in radio, CD, and
DVD player operation.

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. Only punctures located
within the tire tread can be sealed with the
kit.
Do not attempt to repair punctures larger
than ¼ inch (6 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).

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 Information
Messages (page 115).
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.
