2015 FORD MUSTANG engine

You have limited engine power when in the
fail-safe mode, so drive your vehicle with
caution. Your vehicle will not maintain
high-speed operation and the engine will
operate poorly.
Remember that the engine is capable of
automatically shutting down to prevent
engine damage. In this situation:
1. Pull off the road as soon as safely
possible and switch off the engine.
2. Tow your vehicle to an authorized dealer.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and add if low.
5. Re-start the engine and drive your vehicle to an authorized dealer.
Note: Driving your vehicle without repair
increases the chance of engine damage.
Contact an authorized dealer as soon as
possible.
Engine Fluid Temperature
Management (If Equipped) WARNINGS
To reduce the risk of crash and injury,
be prepared that the vehicle speed
may reduce and the vehicle may not
be able to accelerate with full power until
the fluid temperatures reduce. Never remove the coolant reservoir
cap while the engine is running or hot.
Your vehicle can pull a trailer, but because
of the added load, your vehicle
’s engine
may temporarily reach higher
temperatures during severe operating
conditions such as ascending a long or
steep grade while pulling a trailer in high
temperatures. At this time, you may notice your engine
coolant temperature gauge needle move
toward the H and the POWER REDUCED
TO LOWER TEMP 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 fluid
temperatures, your vehicle may enter this
mode if certain high-temperature and
high-load conditions take place. The
amount of speed reduction depends on
many factors such as vehicle loading,
towing, grade and ambient temperature.
If this occurs, there is no need to pull off
the road. You can continue to drive your
vehicle while this message is active.
The air conditioning may also cycle on and
off during severe operating conditions to
protect overheating of the engine. When
the engine coolant temperature decreases
to a normal operating temperature, the air
conditioning will turn on once again.
If the engine coolant temperature gauge
moves fully into the red (hot) area, or if the
coolant temperature warning or service
engine soon messages appear in your
information display:
1. Pull off the road as soon as safely possible and shift the transmission into
P
.
2. Leave the engine running until the coolant temperature gauge needle
moves away from the red (hot) area.
After several minutes, if the
temperature does not drop, follow the
remaining steps.
3. Switch the engine off and wait for it to
cool before checking the coolant level.
4. If the coolant level is normal, restart your engine and continue.

5. If the coolant is low, add coolant, and
restart the engine. See Adding Engine
Coolant or How Fail-Safe Cooling
Works in this chapter for more
information.
MANUAL TRANSMISSION
FLUID CHECK
1. Clean the filler plug. It is located on the
passenger side of the transmission. 2. Remove the filler plug and inspect the
fluid level.
3. For vehicles with a the I4 or V6 engine,
the correct manual transmission fill
level is at the lower edge of the filler
hole. For vehicles equipped with a V8
engine, the correct manual
transmission fill level is 1/2 inch (1.3
cm) below the edge of the filler hole.
4. Add enough fluid through the filler opening to bring the fluid up to the
recommended levels.
5. Install and tighten the fill plug securely.
Only use fluid that meets Ford
specifications. See
Capacities and
Specifications (page 267). AUTOMATIC TRANSMISSION
FLUID CHECK
If required, have an authorized dealer check
and change the transmission fluid at the
correct service interval. See
Scheduled
Maintenance (page 414).
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, if the
transmission slips, shifts slowly or if you
notice a sign of leaking fluid, contact an
authorized dealer.
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.
BRAKE AND CLUTCH FLUID
CHECK
Fluid levels between the MIN and MAX
lines are within the normal operating range;
there is no need to add fluid. If the fluid
levels are outside of the normal operating
range, the performance of the system
could be compromised; seek service from
your authorized dealer immediately.
POWER STEERING FLUID
CHECK
Your vehicle is equipped with an electric
power steering (EPS) system. There is no
fluid reservoir to check or fill.

For longer, trouble-free operation, keep the
top of the battery clean and dry. Also,
make certain the battery cables are always
tightly fastened to the battery terminals.
If you see any corrosion on the battery or
terminals, remove the cables from the
terminals and clean with a wire brush. You
can neutralize the acid with a solution of
baking soda and water.
It is recommended that the negative
battery cable terminal be disconnected
from the battery if you plan to store your
vehicle for an extended period of time.
Because your vehicle
’s engine is
electronically controlled by a computer,
some control conditions are maintained
by power from the battery. When the
battery is disconnected or a new battery
is installed, the engine must relearn its idle
and fuel trim strategy for optimum
driveability and performance. Flexible fuel
vehicles (FFV) must also relearn the
ethanol content of the fuel for optimum
driveability and performance. To begin this
process:
1. With your vehicle at a complete stop, set the parking brake.
2. Put the gearshift in P(Park), turn off all
accessories.
3. Start the engine. Run the engine until it reaches normal operating
temperature.
4. Allow the engine to idle for at least one
minute.
5. Turn the air conditioning on and allow the engine to idle for at least one
minute. 6. Release the parking brake. With your
foot on the brake pedal and with the
air conditioning on, put your vehicle in
D
(Drive) and allow the engine to idle
for at least one minute.
• If you do not allow the engine to
relearn its idle trim, the idle quality
of your vehicle may be adversely
affected until the idle trim is
eventually relearned.
7. Drive your vehicle to complete the relearning process
•Your vehicle may need to be driven
10 miles (16 kilometers) or more to
relearn the idle and fuel trim
strategy along with the ethanol
content for flexible fuel vehicles.
• For flexible fuel vehicles, if you are
operating on E85, you may
experience poor starts or an
inability to start the engine and
driveability problems until the fuel
trim and ethanol content have been
relearned.
If the battery has been disconnected or a
new battery has been installed, the clock
and radio settings must be reset once the
battery is reconnected.
Always dispose of automotive
batteries in a responsible manner.
Follow your local authorized standards
for disposal. Call your local authorized
recycling center to find out more about
recycling automotive batteries.
Battery Management System (If
Equipped)
The battery management system (BMS)
monitors battery conditions and takes
actions to extend battery life. If excessive
battery drain is detected, the system may
temporarily disable certain electrical
features to protect the battery. Those
electrical accessories affected include the
rear defrost, heated/cooled seats, climate

CHANGING THE ENGINE AIR
FILTER
WARNING
To reduce the risk of vehicle damage
and personal burn injuries, do not
start your engine with the air cleaner
removed and do not remove it while the
engine is running. Note:
Failure to use the correct air filter
element may result in severe engine
damage. Your warranty may not cover these
damages.
Use only the air filter element listed when
changing the air filter element. See
Motorcraft Parts (page 268).
Change the air filter element at the proper
intervals. See
Scheduled Maintenance
(page 414). 1. Release the two clamps that secure
the air filter housing cover.
2. Carefully lift the air filter housing cover.
3. Remove the air filter element from the
air filter housing.
4. Wipe any dirt or debris from the air filter
housing and cover to make sure no dirt
gets in the engine and that you have a
good seal. 5. Install a new air filter element. Be
careful not to crimp the filter element
edges between the air filter housing
and cover. This could cause filter
damage and allow unfiltered air to
enter the engine if it is not properly
seated.
6. Replace the air filter housing cover.
7. Engage the clamps to secure the air filter housing cover to the air filter
housing.

228
Mustang (), enUSA, First Printing Vehicle Care

•
Wash your vehicle first, using cool or
lukewarm water and a neutral pH
shampoo, such as Motorcraft Detail
Wash.
• Use Motorcraft Custom Bright Metal
Cleaner. Apply the product as you
would a wax to clean bumpers and
other chrome parts; allow the cleaner
to dry for a few minutes, then wipe off
the haze with a clean, dry rag.
• Do not apply cleaning product to hot
surfaces and do not leave cleaning
product on chrome surfaces longer
than the time recommended.
• Using other non-recommended
cleaners can result in severe and
permanent cosmetic damage.
Underbody
Flush the complete underside of your
vehicle frequently. Keep body and door
drain holes free from packed dirt.
Cleaning Plastic Exterior Parts
Use only approved products to clean
plastic parts
• For routine cleaning, use Motorcraft
Detail Wash.
• If tar or grease spots are present, use
Motorcraft Bug and Tar Remover.
WAXING
Regular waxing is necessary to protect your
car's paint from the elements. We
recommend that you wash and wax the
painted surface once or twice a year.
When washing and waxing, park your
vehicle in a shaded area out of direct
sunlight. Always wash your vehicle before
applying wax. •
Use a quality wax that does not contain
abrasives.
• Follow the manufacturer ’s instructions
to apply and remove the wax.
• Apply a small amount of wax in a
back-and-forth motion, not in circles.
• Do not allow wax to come in contact
with any non-body (low-gloss black)
colored trim. The wax will discolor or
stain the parts over time.
•Roof racks.
• Bumpers.
• Grained door handles.
• Side moldings.
• Mirror housings.
• Windshield cowl area.
• Do not apply wax to glass areas.
• After waxing, your car's paint should
feel smooth, and be free of streaks and
smudges.
CLEANING THE ENGINE
Engines are more efficient when they are
clean because grease and dirt buildup keep
the engine warmer than normal.
When washing:
• Take care when using a power washer
to clean the engine. The high-pressure
fluid could penetrate the sealed parts
and cause damage.
• Do not spray a hot engine with cold
water to avoid cracking the engine
block or other engine components.
• Spray Motorcraft Engine Shampoo and
Degreaser on all parts that require
cleaning and pressure rinse clean. In
Canada, use Motorcraft Engine
Shampoo.
• Never wash or rinse the engine while it
is hot or running; water in the running
engine may cause internal damage.
229
Mustang (), enUSA, First Printing Vehicle Care

•
Never wash or rinse any ignition coil,
spark plug wire or spark plug well, or
the area in and around these locations.
• Cover the battery, power distribution
box, and air filter assembly to prevent
water damage when cleaning the
engine.
CLEANING THE WINDOWS AND
WIPER BLADES
Car wash chemicals and environmental
fallout can result in windshield and wiper
blade contamination. Dirty windshield and
wipers will result in poor windshield wiper
operation. Keep the windshield and wiper
blades clean to maintain windshield wiper
performance.
To clean the windshield and wiper blades:
• Clean the windshield with a
non-abrasive glass cleaner.
• For windshields contaminated with
tree sap, chemicals, wax or bugs, clean
the entire windshield using steel wool
(no greater than 0000 grade) in a
circular motion and rinse with water.
• Clean the wiper blades with isopropyl
rubbing alcohol or windshield washer
concentrate.
Note: Do not use razor blades or other
sharp objects to clean or remove decals
from the inside of the heated rear window.
The vehicle warranty does not cover
damage caused to the heated rear window
grid lines.
CLEANING THE INTERIOR WARNINGS
Do not use cleaning solvents, bleach
or dye on the vehicle
’s safety belts,
as these actions may weaken the
belt webbing. WARNINGS
On vehicles equipped with
seat-mounted airbags, do not use
chemical solvents or strong
detergents. Such products could
contaminate the side airbag system and
affect performance of the side airbag in a
collision. For fabric, carpets, cloth seats, safety belts
and seats equipped with side airbags:
•
Remove dust and loose dirt with a
vacuum cleaner.
• Remove light stains and soil with
Motorcraft Professional Strength
Carpet & Upholstery Cleaner.
• If grease or tar is present on the
material, spot-clean the area first with
Motorcraft Spot and Stain Remover. In
Canada, use Motorcraft Multi-Purpose
Cleaner.
• If a ring forms on the fabric after spot
cleaning, clean the entire area
immediately (but do not oversaturate)
or the ring will set.
• Do not use household cleaning
products or glass cleaners, which can
stain and discolor the fabric and affect
the flame retardant abilities of the seat
materials.
CLEANING THE INSTRUMENT
PANEL AND INSTRUMENT
CLUSTER LENS WARNING
Do not use chemical solvents or
strong detergents when cleaning the
steering wheel or instrument panel
