2018 FORD MUSTANG fuel cap

To avoid fluid contamination, the reservoir
cap must remain in place and fully tight,
unless you are adding fluid.
Only use fluid that meets Ford
specifications. See Capacities and
Specifications (page 290).
CLUTCH FLUID CHECK -
MANUAL TRANSMISSION
The clutch and brake systems share the
same fluid reservoir. See
Brake Fluid
Check (page 238).
POWER STEERING FLUID
CHECK
Your vehicle is equipped with an electric
power steering (EPS) system. There is no
fluid reservoir to check or fill. 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
Capacities and
Specifications (page 290).
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.
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.
CHANGING THE 12V BATTERY WARNINGS
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 correct
ventilation.

WARNINGS
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. 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. Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash hands after
handling. This vehicle may have more than one
battery. Removing the battery cables
from only one battery does not
disconnect your vehicle electrical system.
Make sure you disconnect the battery
cables from all batteries when
disconnecting power. Failure to do so may
cause serious personal injury or property
damage. Your vehicle is fitted with a Motorcraft
maintenance-free battery which normally
does not require additional water.
When a battery replacement is required,
you must use a recommended
replacement battery that matches the
electrical requirements of the vehicle.
Note:
After cleaning or replacing the
battery, make sure you reinstall the battery
cover or shield. Note:
If you add electrical accessories or
components to the vehicle, it may adversely
affect the low voltage battery performance
and durability. This may also affect the
performance of other electrical systems in
the vehicle.
For longer, trouble-free operation, keep the
top of the battery clean and dry.
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.
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 restore the settings, do the following:
1. Apply the parking brake.
2. Shift into park (P) or neutral (N).
3. Switch off all accessories.
4. Press the brake pedal and start your vehicle.
5. Run the engine until it reaches normal operating temperature. While the
engine is warming up, complete the
following: Reset the clock. Reset the
power windows bounce-back feature.
See Windows and Mirrors (page 77).
Reset the radio station presets. See
Audio System
(page 306).
6. Allow the engine to idle for at least one
minute.
7. Drive the vehicle at least 10 mi (16 km)
to completely relearn the idle trim and
fuel trim strategy.

Do not use supplemental engine oil
additives because they are unnecessary
and could lead to engine damage that may

Note:
Ford recommends using DOT 4 Low
Viscosity (LV) High Performance Brake Fluid
or equivalent meeting WSS-M6C65-A2. Use
of any fluid other than the recommended
fluid may cause degraded brake
performance and not meet the Ford
performance standards. Keep brake fluid
clean and dry. Contamination with dirt,
water, petroleum products or other
materials may result in brake system
damage and possible failure.
Note: Automatic transmissions that require
MERCON® LV transmission fluid should
only use MERCON® LV transmission fluid.
The use of any other fluid may cause
transmission damage.
Alternative Engine Oil for
Extremely Cold Climates
To improve engine cold start performance,
we recommend that you use the following
alternative engine oil in extremely cold
climates, where the ambient temperature
reaches -22.0°F (-30°C) or below.

To make sure that 911 Assist works
properly:
• SYNC must be powered and working
properly at the time of the incident and
throughout feature activation and use.
• The 911 Assist feature must be set on
before the incident.
• You must pair and connect a
Bluetooth-enabled and compatible
cell phone to SYNC.
• A connected Bluetooth-enabled phone
must have the ability to make and
maintain an outgoing call at the time
of the incident. •
A connected Bluetooth-enabled phone
must have adequate network coverage,
battery power and signal strength.
• The vehicle must have battery power
and be located in the U.S., Canada or
in a territory in which 911 is the
emergency number.
In the Event of a Crash
Not all crashes deploy an airbag or activate
the fuel pump shut-off (the triggers for 911
Assist). If a connected cell phone sustains
damage or loses its connection to SYNC
during a crash, SYNC searches for and tries
to connect to a previously paired cell
phone; SYNC then attempts to call the
emergency services.
Before making the call:
• SYNC provides a short window of time
(about 10 seconds) to cancel the call.
If you fail to cancel the call, SYNC
attempts to dial 911.
• SYNC says the following, or a similar
message: "SYNC will attempt to call
911, to cancel the call, press Cancel on
your screen or press and hold the
phone button on your steering wheel".
If you do not cancel the call, and SYNC
makes a successful call, a pre-recorded
message plays for the 911 operator, and
then the occupant(s) in your vehicle is able
to talk with the operator. Be prepared to
provide your name, phone number and
location immediately, because not all 911
systems are capable of receiving this
information electronically.
911 Assist May Not Work If
• Your cellular phone or 911 Assist
hardware sustains damage in a crash.
• The vehicle's battery or the SYNC
system has no power.
• The phone(s) thrown from your vehicle
are the ones paired and connected to
the system.
