2014 FORD MUSTANG maintenance

•Do not use alcohol, methanol, brine or any engine coolants mixed with
alcohol or methanol antifreeze (coolant). 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 engine
coolant.
Unscrew the cap slowly. Any pressure will escape as you unscrew the
cap.
Add prediluted engine coolant meeting the Ford specification. See the
technical specifications chart in theCapacities and Specifications
chapter.
Whenever coolant has been added, the coolant level in the coolant
reservoir should be checked the next few times you drive the vehicle.
If necessary, add enough prediluted engine coolant to bring the coolant
level to the proper level.
Recycled Engine Coolant
Ford Motor Company does NOT recommend the use of recycled engine
coolant since a Ford-approved recycling process is not yet available.
Used engine coolant should be disposed of 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 have a Ford authorized dealer increase the
coolant concentration above 50%.
•A coolant concentration of 60% will provide improved freeze point
protection. Increased engine coolant concentrations above 60% will
decrease the overheat protection characteristics of the engine coolant
and may cause engine damage.
If you drive in extremely hot climates:
•It may be necessary to have a Ford authorized dealer decrease the
coolant concentration to 40%.
•A coolant concentration of 40% will provide improved overheat
protection. Decreased engine coolant concentrations below 40% will
decrease the corrosion and freeze 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 ambient temperatures, vehicle load and
terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat:
•The engine coolant temperature gauge will move to the red (hot)
area.
•The service engine soon indicator will illuminate.
•The coolant temperature warning light will illuminate.
If the engine reaches a preset over-temperature condition, the engine
will automatically switch to alternating cylinder operation. Each disabled
cylinder acts as an air pump and cools the engine.
When this occurs the vehicle will still operate. However:
•The engine power will be limited.
•The air conditioning system will be disabled.
Continued operation will increase the engine temperature and the engine
will completely shut 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
You have limited engine power when in the fail-safe mode, so drive the
vehicle with caution. The vehicle will not be able to maintain high-speed
operation and the engine will run rough. Remember that the engine is
capable of completely shutting down automatically to prevent engine
damage, therefore:
1. Pull off the road as soon as safely possible and turn off the engine.
2. Arrange for the vehicle to be taken 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 replenish if low.
WARNING:Fail-safe mode is for use during emergencies only.
Operate the vehicle in fail-safe mode only as long as necessary to
bring the vehicle to rest in a safe location and seek immediate repairs.
When in fail-safe mode, the 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.
WARNING:Never remove the coolant reservoir cap while the
engine is running or hot. The hot coolant is under pressure and
may cause serious burns.
5. Re-start the engine and take your vehicle to an authorized dealer.
Note:Driving the vehicle without repairing the engine problem increases
the chance of engine damage. Take your vehicle to an authorized dealer
as soon as possible.

TRANSMISSION FLUID CHECK
Checking Automatic Transmission Fluid
Note:Transmission fluid should be checked and, if required, added by
an authorized dealer.
The automatic transmission does not have a transmission fluid dipstick.
See yourScheduled Maintenance Informationfor 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, (i.e., if the transmission slips or shifts slowly) or if you
notice some sign of fluid leakage.
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 and Adding Manual Transmission Fluid (if equipped)
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 equipped with aV6engine, the correct manual
transmission fill level is at the lower edge of the filler hole. For vehicles
equipped with aV8engine, the correct manual transmission fill level is
1/2 in (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.
Use only fluid that meets Ford specifications. See the technical
specifications chart in theCapacities and Specificationschapter.

BRAKE AND CLUTCH FLUID CHECK
Brake and clutch (if equipped) systems are supplied from the same
reservoir.
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.
FUEL FILTER
Your vehicle is equipped with a lifetime fuel filter that is integrated with
the fuel tank. Regular maintenance or replacement is not needed.
For Shelby fuel filter requirements, see theShelby GT500 Supplement.
WASHER FLUID CHECK
WARNING:If you operate your vehicle in temperatures below
40°F (5°C), use washer fluid with antifreeze protection. Failure
to use washer fluid with antifreeze protection in cold weather could
result in impaired windshield vision and increase the risk of injury or
accident.
Add fluid to fill the reservoir if the level is low. Only use a washer fluid
that meets Ford specifications. See the technical specifications chart in
theCapacities and Specificationschapter.
State or local regulations on volatile organic compounds may restrict the
use of methanol, a common windshield washer antifreeze additive.
Washer fluids containing non-methanol antifreeze agents should be used
only if they provide cold weather protection without damaging the
vehicle’s paint finish, wiper blades or washer system.

CHANGING THE VEHICLE BATTERY
WARNING:Batteries normally produce explosive gases which
can cause personal injury. Therefore, do not allow flames, sparks
or lighted substances to come near the battery. When working near the
battery, always shield your face and protect your eyes. Always provide
proper ventilation.
WARNING:When lifting a plastic-cased battery, excessive
pressure on the end walls could cause acid to flow through the
vent caps, resulting in personal injury and damage to the vehicle or
battery. Lift the battery with a battery carrier or with your hands on
opposite corners.
WARNING:Keep batteries out of reach of children. Batteries
contain sulfuric acid. Avoid contact with skin, eyes or clothing.
Shield your eyes when working near the battery to protect against
possible splashing of acid solution. In case of acid contact with skin or
eyes, flush immediately with water for a minimum of 15 minutes and
get prompt medical attention. If acid is swallowed, call a physician
immediately.
WARNING:Battery posts, terminals and related accessories
contain lead and lead compounds. Wash hands after handling.
Your vehicle is equipped with a Motorcraft® maintenance-free battery
which normally does not require additional water during its life of
service.
Note:If your battery has a cover or a shield, make sure it is reinstalled
after the battery has been cleaned or replaced.
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.

Battery Relearn
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. To begin this process:
1. With the vehicle at a complete stop, set the parking brake.
2. Put the gearshift in position P (automatic transmission) or the neutral
position (manual transmission), turn off all accessories and start the
engine.
3. Run the engine until it reaches normal operating temperature.
4. Allow the engine to idle for at least one minute.
5. Turn the A/C on and allow the engine to idle for at least one minute.
6. Drive the vehicle to complete the relearning process.
•The vehicle may need to be driven 10 mi (16 km) or more to relearn
the idle and fuel trim strategy.
•Note: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.
When the battery is disconnected or a new battery installed, the
transmission must relearn its adaptive strategy. As a result of this, the
transmission may shift firmly. This operation is considered normal and
will not affect function or durability of the transmission. Over time the
adaptive learning process will fully update transmission operation to its
optimum shift feel.
If the battery has been disconnected or a new battery has been installed,
the clock and the preset radio stations 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.

CHECKING THE WIPER BLADES
Run the tip of your fingers over the edge of the blade
to check for roughness.
Clean the wiper blades with washer fluid or water
applied with a soft sponge or cloth.
CHANGING THE WIPER BLADES
1. Pull the wiper blade and arm away
from the glass.
2. Squeeze the locking tabs to release
the blade from the arm and pull the
blade away from the arm to remove it.
3. Attach the new blade to the arm
and snap it into place.
Replace wiper blades at least once per
year for optimum performance.
Poor wiper quality can be improved by
cleaning the wiper blades and the
windshield.
To prolong the life of the wiper
blades, it is highly recommended to
scrape off the ice on the windshield
before turning on the wipers. The layer of ice has many sharp edges and
can damage the micro edge of the wiper rubber element.
AIR FILTER CHECK
WARNING:To reduce the risk of vehicle damage and or
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. The customer warranty may be void for any damage to
the engine if the correct air filter element is not used.
When changing the air filter element, use only the air filter element
listed. SeeMotorcraft® Part Numbersin theCapacities and
Specificationschapter.
