overheating FORD MUSTANG 2018 Owners Manual

Additional Warranty Information
Your vehicle carries the same warranty as
other Ford models. This information is
covered in its entirety in the Ford Warranty
Guide. You can obtain warranty service for
your vehicle at any authorized dealer
nationwide.
We design and build our vehicles for our
customers to drive as delivered from the
factory. The Ford Warranty Guide
discusses vehicle use and the installation
of aftermarket parts and their effect on
warranty coverage. See the Ford Warranty
Guide for complete information.
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 438).
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.

Press and hold the function button you
want to program for 2 seconds, then
release. Repeat this step. Depending
on your brand of garage door opener,
you may need to repeat this sequence
a third time.
Gate Operator / Canadian
Programming
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit)
after several seconds of transmission –
which may not be long enough for
HomeLink to pick up the signal during
programming. Similar to this Canadian law,
some U.S. gate operators are designed to
“time-out” in the same manner.
Note: If programming a garage door opener
or gate operator, it is advised to unplug the
device during the “cycling” process to
prevent possible overheating.
1. Press and release, every two seconds,
your hand-held transmitter until the
HomeLink indicator light changes to a
rapidly blinking or continuously on light.
2. Release the hand-held transmitter button.
3. Continue programing HomeLink. See In-Vehicle Programming, Step 4.
Erasing the Function Button Codes
Note: You cannot erase individual buttons. 1. Press and hold the outer two function
buttons simultaneously for
approximately 10 seconds until the
indicator light above the buttons
flashes rapidly.
2. When the indicator light flashes, release the buttons. You erased the
codes for all buttons.
Reprogramming a Single Button
To program a device to a previously trained
button, follow these steps:
1. Press and hold the desired button. Do NOT release the button.
2. The indicator light begins to flash after
20 seconds. Without releasing the
button, follow Step 1 in the
Programming section.

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)
.
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. Detection Issues WARNINGS
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. If the system malfunctions, have your
vehicle checked as soon as possible.
The radar sensor has a limited field of view.
It may not detect vehicles at all or detect
a vehicle later than expected in some
situations. The lead vehicle graphic does
not illuminate if the system does not
detect a vehicle in front of you.

Note:
The system may not correctly operate
when towing a trailer. For vehicles with a
trailer tow module and tow bar approved
by us, the system turns off when you attach
a trailer. For vehicles with an aftermarket
trailer tow module or tow bar, we
recommend that you switch the system off
when you attach a trailer.
To permanently switch the system off,
contact an authorized dealer.
STEERING
Electric Power Steering WARNINGS
The electric power steering system
has diagnostic checks that
continuously monitor the system. If
a fault is detected, a message displays in
the information display. Stop your vehicle
as soon as it is safe to do so. Switch the
ignition off. After at least 10 seconds,
switch the ignition on and watch the
information display for a steering system
warning message. If a steering system
warning message returns, have the system
checked by an authorized dealer. If the system detects an error, you
may not feel a difference in the
steering, however a serious condition
may exist. Obtain immediate service from
an authorized dealer, failure to do so may
result in loss of steering control. Your vehicle has an electric power steering
system. There is no fluid reservoir. No
maintenance is required.
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.

BREAKING-IN
Tires
New tires need to be run-in for
approximately 300 mi (500 km). During
this time, you may experience different
driving characteristics.
Brakes and Clutch
Avoid heavy use of the brakes and clutch
if possible for the first
100 mi (150 km) in
town and for the first 1,000 mi (1,500 km)
on freeways.
Engine
Avoid driving too fast during the first
1,000 mi (1,500 km)
. Vary your speed
frequently and change up through the
gears early. Do not labor the engine.
REDUCED ENGINE
PERFORMANCE WARNING
If you continue to drive your vehicle
when the engine is overheating, the
engine could stop without warning.
Failure to follow this instruction could
result in the loss of control of your vehicle. If the engine coolant temperature gauge
needle moves to the upper limit position,
the engine is overheating. See
Gauges
(page 81).
You must only drive your vehicle for a short
distance if the engine overheats. The
distance you can travel depends on
ambient temperature, vehicle load and
terrain. The engine continues to operate
with limited power for a short period of
time. If the engine temperature continues to rise,
the fuel supply to the engine reduces. The
air conditioning switches off and the engine
cooling fan operates continually.
1. Gradually reduce your speed and stop
your vehicle as soon as it is safe to do
so.
2. Immediately switch the engine off to prevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level. See
Engine
Coolant Check (page 234).
5. Have your vehicle checked as soon as possible.
ECONOMICAL DRIVING
Fuel economy is affected by several things
such as how you drive, the conditions you
drive under and how you maintain your
vehicle.
There are some things to keep in mind that
may improve your fuel economy:
• Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds.
• Anticipate stops; slowing down may
eliminate the need to stop.
• Combine errands and minimize
stop-and-go driving (When running
errands, go to the furthest destination
first and then work your way back
home).
• Close the windows for high-speed
driving.
• Drive at reasonable speeds.
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.

Note:
Coolants marketed for all makes and
models may not be approved to our
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
290).
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. 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.
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.
