2017 FORD MUSTANG engine overheat

Using your vehicle on a dedicated road
course may result in degraded function
and failure of major systems such as the
engine, transmission and rear axle due to
the overheating of these systems. If you
intend to use your vehicle on a dedicated
road course, we suggest that you equip
your vehicle with racing-type coolers to
protect these three systems.
In addition, if the vehicle is subjected to
dedicated road course use, we recommend
the following vehicle durability
maintenance:
•
Change your axle lubricant and friction
modifier after the initial (first) hour of
high-speed operation; thereafter
change the axle lubricant and friction
modifier every 12 hours (under these
conditions).
• Change your transmission oil after each
event where your vehicle is subjected
to individual on-track sessions
exceeding 15 minutes.
• Change your engine oil and filter after
each event.
Additionally, perform a multi-point
inspection on items specified in the
scheduled maintenance section of this
owner guide before and after dedicated
road course use. See General
Maintenance Information (page 417).
See the vehicle service manual for removal
and installation procedures. Replace with
Genuine Ford and Motorcraft™ service
parts as needed.
These actions may not necessarily protect
your powertrain from damage in dedicated
road course use. Subjecting your vehicle
to dedicated road course use even with
these proposed precautions may render
repairs non-reimbursable under the
warranty. Special Instructions
For your added safety, your vehicle is fitted
with sophisticated electronic controls. WARNINGS
You risk death or serious injury to
yourself and others if you do not
follow the instruction highlighted by
the warning symbol. Failure to follow the
specific warnings and instructions could
result in personal injury. Never
place front seat mounted
rear-facing child or infant seats in
front of an active passenger airbag. On Board Diagnostics Data Link
Connector
Note:
Use of wireless plug-in devices in the
OBD Data Link Connector (DLC) may allow
unauthorized third parties to gain access to
vehicle systems and data which could
impair the function of various vehicle
systems, including safety-related systems.
The DLC should only be used by a repair
facility that operates in accordance with
Ford ’s service and repair instructions.
Your vehicle has an OBD Data Link
Connector (DLC) that is used in
conjunction with a diagnostic scan tool for
vehicle diagnostics, repairs and
reprogramming services. Installing an
aftermarket device that uses the DLC
during normal driving for purposes such as
remote insurance company monitoring,
transmission of vehicle data to other
devices or entities, or altering the
performance of the vehicle, may cause
interference with or even damage to
vehicle systems. We do not recommend
or endorse the use of aftermarket plug-in
devices unless approved by Ford. The
vehicle Warranty will not cover damage
caused by an aftermarket plug-in device.

injury, medication, alcohol use, exhaustion,
or other physical conditions, must exercise
care when using the seat heater. The seat
heater may cause burns even at low
temperatures, especially if used for long
periods of time. Do not place anything on
the seat that insulates against heat, such
as a blanket or cushion, because this may
cause the seat heater to overheat. Note:
Do not do the following:
• Place heavy objects on the seat.

Use the brake shift interlock lever to move
the gearshift lever from the park position
in the event of an electrical malfunction or
if your vehicle has a dead battery.
Apply the parking brake and switch the
ignition off before performing this
procedure.
1.
Using a flat head screwdriver or similar
tool, remove the chrome bezel and
gearshift bracket at the base of the
gearshift lever. 2.
Locate the white release lever and slide
the lever forward while pulling the
gearshift lever out of the park (P)
position and into the neutral (N)
position.
3. Reinstall the console.
4. Start your vehicle and release the parking brake. Automatic Transmission Adaptive
Learning
This feature is designed to increase
durability and provide consistent shift feel
over the life of your vehicle. A new vehicle
or transmission may have firm or soft
shifts. This operation is normal and does
not affect function or durability of the
transmission. Over time, the adaptive
learning process will fully update
transmission operation. Additionally,
whenever you disconnect the battery is or
install a new battery, the system must
relearn the strategy.
If Your Vehicle Gets Stuck In Mud
or Snow
Note:
Do not rock your vehicle if the engine
is not at normal operating temperature or
damage to the transmission may occur.
Note: Do not rock your 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.

Note:
Only use resume if you are aware of
the set speed and intend to return to it.
Automatic Cancellation
The system is not functional at vehicle
speeds below 12 mph (20 km/h). An
audible alarm sounds and the automatic
braking releases if your vehicle drops below
this speed. The system cancels at low
speeds if you switch off electronic stability
control.
Hilly Condition Usage
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.
Note: An audible alarm sounds and the
system shuts down if it is applying brakes
for an extended period of time. This allows
the brakes to cool down. The system
functions normally again when the brakes
have cooled down.
Switching the System Off
Press and release
OFF when the system
is in stand by mode or switch off the
ignition.
Note: You erase the set speed when you
switch the system off. Detection Issues WARNING
On rare occasions, detection issues
can occur due to the road
infrastructures, for example bridges,
tunnels and safety barriers. In these cases,
the system may brake late or
unexpectedly. At all times, you are
responsible for controlling your vehicle,
supervising the system and intervening, if
required. 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 vehicle graphic does
not appear in the information display if the
system does not detect a vehicle in front
of you.

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 park (P) (automatic
transmission) or neutral (manual
transmission) to aid engine and
transmission cooling and to help air
conditioning performance.
• Switch 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:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the automatic transmission in park (P) or manual transmission in a
low gear. 4. 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.
Note: Reconnect the wiring to the trailer
after
removing the trailer from the water.
When backing down a ramp during boat
launching or retrieval:
• Do not allow the static water level to
rise above the bottom edge of the rear
bumper.
• Do not allow waves to break higher
than 6 inches (15 centimeters) above
the bottom edge of the rear bumper.
Exceeding these limits may allow water to
enter vehicle components:
• Causing internal damage to the
components.
• Affecting driveability, emissions, and
reliability.
Any time the rear axle submerges in water,
replace the rear axle lubricant. Water may
contaminate the rear axle lubricant, which
is not a normal maintenance inspection
item unless there is a possibility of a leak
or other axle repair is required.
TOWING THE VEHICLE ON
FOUR WHEELS
Emergency Towing WARNING
If your vehicle has a steering wheel
lock make sure the ignition is in the
accessory or on position when being
towed. 181

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 272). 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 272).
Using w

ater 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
272
).
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.
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.
Note: In case of emergency, you can add a
large amount of water without coolant in
order to reach a vehicle service location.
Water alone, without coolant, can cause
engine damage from corrosion, overheating
or freezing. When you reach a service
location, you must have the cooling system
drained and refilled with prediluted coolant
approved to the correct specification. See
Capacities and Specifications (page 272).
Do not us

e the following as a coolant
substitute:
• Alcohol.
• Methanol.
218
Mustang (CZG) Canada/United States of America, Vehicles Built From: 02-05-2016, enUSA, First Printing Maintenance

•
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. 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 272).
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.
