SITTING IN THE CORRECT
POSITION
WARNING: Sitting improperly, out
of position or with the seatback reclined
too far can take weight off the seat
cushion and affect the decision of the
passenger sensing system, resulting in
serious injury or death in the event of a
crash. Always sit upright against your
seat back, with your feet on the floor. WARNING:
Do not recline the
seatback too far as this can cause the
occupant to slide under the seatbelt,
resulting in serious injury in the event of
a collision. WARNING:
Do not place objects
higher than the top of the seat backrest.
Failure to follow this instruction could
result in personal injury or death in the
event of a sudden stop or crash. When you use them properly, the seat,
head restraint, seatbelt and airbags will
provide optimum protection in the event
of a crash. We recommend that you follow these
guidelines:
•
Sit in an upright position with the base
of your spine as far back as possible.
• Do not recline the seat backrest so that
your torso is more than
30° from the
upright position.
• Adjust the head restraint so that the
top of it is level with the top of your
head and as far forward as possible.
Make sure that you remain
comfortable.
• Keep sufficient distance between
yourself and the steering wheel. We
recommend a minimum of
10 in
(25 cm) between your breastbone and
the airbag cover.
• Hold the steering wheel with your arms
slightly bent.
• Bend your legs slightly so that you can
press the pedals fully.
• Position the shoulder strap of the
seatbelt over the center of your
shoulder and position the lap strap
tightly across your hips.
Make sure that your driving position is
comfortable and that you can maintain full
control of your vehicle.
HEAD RESTRAINTS WARNING:
Fully adjust the head
restraint before you operate your vehicle.
This will help minimize the risk of neck
injury in the event of a crash. Do not
adjust the head restraint when your
vehicle is moving.

WARNING: Do not use the system
with any garage door opener that does
not have the safety stop and reverse
feature as required by U.S. Federal
Safety Standards (this includes any
garage door opener manufactured
before April 1, 1982). A garage door
opener which cannot detect an object,
signaling the door to stop and reverse,
does not meet current federal safety
standards. Using a garage door opener
without these features increases the risk
of serious injury or death.
Note: Make sure that the garage door and
security device are free from obstruction
when you are programming. Do not program
the system with the vehicle in the garage.

remote control transmitter for use in other
vehicles as well as for future system
programming.
Note: We recommend that upon the sale
or lease termination of your vehicle, you
erase the programmed function buttons for
security reasons. See Erasing the Function
Button Codes
later in this section.
Note: You can program a maximum of
three devices. To change or replace any of
the three devices after it has been initially
programmed, you must first erase the
current settings. See Erasing the Function
Button Codes
. The universal garage door opener replaces
the common hand-held garage door
opener with a three-button transmitter
integrated into the driver
’s sun visor.
The system includes two primary features,
a garage door opener and a platform for
remote activation of devices within the
home. You can program garage doors as

Some fuel stations, particularly those in
high altitude areas, offer fuels posted as
regular unleaded gasoline with an octane
rating below 87. The use of these fuels
could result in engine damage that will not
be covered by the vehicle warranty.
For best overall vehicle and engine
performance, premium fuel with an octane
rating of 91 or higher is recommended. The
performance gained by using premium fuel
is most noticeable in hot weather as well
as other conditions, for example when
towing a trailer. See Towing (page 197).
Do not be concerned if the engine
sometimes knocks lightly. However, if the
engine knocks heavily while using fuel with
the recommended octane rating, contact
an authorized dealer to prevent any engine
damage.
We recommend Top Tier detergent
gasolines, where available to help minimize
engine deposits and maintain optimal
vehicle and engine performance. For
additional information, refer to
www.toptiergas.com.
Note: Use of any fuel for which the vehicle
was not designed can impair the emission
control system, cause loss of vehicle
performance, and cause damage to the
engine which may not be covered by the
vehicle Warranty.
Do not use:
• Diesel fuel.
• Fuels containing kerosene or paraffin.
• Fuel containing more than 15% ethanol
or E85 fuel.
• Fuels containing methanol.
• Fuels containing metallic-based
additives, including manganese-based
compounds. •
Fuels containing the octane booster
additive, methylcyclopentadienyl
manganese tricarbonyl (MMT).
• Leaded fuel, using leaded fuel is
prohibited by law.
The use of fuels with metallic compounds
such as methylcyclopentadienyl
manganese tricarbonyl (commonly known
as MMT), which is a manganese-based
fuel additive, will impair engine
performance and affect the emission
control system.
FUEL FILLER FUNNEL
LOCATION
The fuel filler funnel is under the luggage
compartment floor covering.
RUNNING OUT OF FUEL
Running out of fuel can cause damage not
covered by the vehicle Warranty.
If your vehicle runs out of fuel:
• Add a minimum of
1.3 gal (5 L) of fuel
to restart the engine.
• You may need to switch the ignition
from off to on several times after
refueling to allow the fuel system to
pump the fuel from the tank to the
engine. When restarting, cranking time
takes a few seconds longer than
normal.
Note: If your vehicle is on a steep slope,
more fuel may be required.
Filling a Portable Fuel Container WARNING:
Flow of fuel through a
fuel pump nozzle can produce static
electricity. This can cause a fire if you are
filling an ungrounded fuel container.

EMISSION LAW
WARNING: Do not remove or alter
the original equipment floor covering or
insulation between it and the metal floor
of the vehicle. The floor covering and
insulation protect occupants of the
vehicle from the engine and exhaust
system heat and noise. On vehicles with
no original equipment floor covering
insulation, do not carry passengers in a
manner that permits prolonged skin
contact with the metal floor. Failure to
follow these instructions may result in
fire or personal injury.
U.S. federal laws and certain state laws
prohibit removing or rendering inoperative
emission control system components.
Similar federal or provincial laws may
apply in Canada. We do not approve of any
vehicle modification without first
determining applicable laws. Tampering with emissions
control systems including
related sensors or the Diesel
Exhaust Fluid system can result in reduced
engine power and the illumination of the
service engine soon light. Tampering With a Noise Control
System
Federal laws prohibit the following acts:
•
Removal or rendering inoperative by
any person other than for purposes of
maintenance.
• Repair or replacement of any device or
element of the design incorporated into
a new vehicle for the purpose of noise
control prior to its sale or delivery to
the ultimate purchaser or while it is in
use.
• The use of the vehicle after any person
removes or renders inoperative any
device or element of the design.
The U.S. Environmental Protection Agency
may presume to constitute tampering as
follows:
• Removal of hood blanket, fender apron
absorbers, fender apron barriers,
underbody noise shields or acoustically
absorptive material.
• Tampering or rendering inoperative the
engine speed governor, to allow engine
speed to exceed manufacturer
specifications.
If the engine does not start, runs rough,
experiences a decrease in engine
performance, experiences excess fuel
consumption or produces excessive
exhaust smoke, check for the following:
• A plugged or disconnected air inlet
system hose.
• A plugged engine air filter element.
• Water in the fuel filter and water
separator.
• A clogged fuel filter.
• Contaminated fuel.
• Air in the fuel system, due to loose
connections.
• An open or pinched sensor hose.
• Incorrect engine oil level.

Mustang (CZG) Canada/United States of America, Vehicles Built From: 15-07-2019, enUSA, Edition date: 201906, Second-Printing Engine Emission Control

Illumination of the service engine soon
indicator, charging system warning light or
the temperature warning light, fluid leaks,
strange odors, smoke or loss of engine
power could indicate that the emission
control system is not working properly.
An improperly operating or damaged
exhaust system may allow exhaust to
enter the vehicle. Have a damaged or
improperly operating exhaust system
inspected and repaired immediately.
Do not make any unauthorized changes to
your vehicle or engine. By law, vehicle
owners and anyone who manufactures,
repairs, services, sells, leases, trades
vehicles, or supervises a fleet of vehicles
are not permitted to intentionally remove
an emission control device or prevent it
from working. Information about your
vehicle
’s emission system is on the Vehicle
Emission Control Information Decal
located on or near the engine. This decal
also lists engine displacement.
Please consult your warranty information
for complete details.
On-Board Diagnostics (OBD-II)
Your vehicle has a computer known as the
on-board diagnostics system (OBD-II) that
monitors the engine ’s emission control
system. The system protects the
environment by making sure that your
vehicle continues to meet government
emission standards. The OBD-II system
also assists a service technician in properly
servicing your vehicle. When the service engine soon
indicator illuminates, the OBD-II
system has detected a
malfunction. Temporary malfunctions may
cause the service engine soon indicator to
illuminate. Examples are: 1. Your vehicle has run out of fuel
—the
engine may misfire or run poorly.
2. Poor fuel quality or water in the fuel —the engine may misfire or run
poorly.
3. The fuel fill inlet may not have closed properly. See Refueling (page 139).
4. Driving through deep water —the
electrical system may be wet.
You can correct these temporary
malfunctions by filling the fuel tank with
good quality fuel, properly closing the fuel
fill inlet or letting the electrical system dry
out. After three driving cycles without these
or any other temporary malfunctions
present, the service engine soon indicator
should stay off the next time you start the
engine. A driving cycle consists of a cold
engine startup followed by mixed city and
highway driving. No additional vehicle
service is required.
If the service engine soon indicator remains
on, have your vehicle serviced at the first
available opportunity. Although some
malfunctions detected by the OBD-II may
not have symptoms that are apparent,
continued driving with the service engine
soon indicator on can result in increased
emissions, lower fuel economy, reduced
engine and transmission smoothness and
lead to more costly repairs.
Readiness for Inspection and
Maintenance (I/M) Testing
Some state and provincial and local
governments may have
Inspection/Maintenance (I/M) programs
to inspect the emission control equipment
on your vehicle. Failure to pass this
inspection could prevent you from getting
a vehicle registration. If the service engine soon
indicator is on or the bulb does
not work, your vehicle may need
service. See On-Board Diagnostics.

GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out and an
authorized dealer should check them. If the
vehicle has continuous vibration or shudder
in the steering wheel while braking, an
authorized dealer should check your vehicle.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See Cleaning the Wheels
(page 260).
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedal
becomes stuck or entrapped, apply steady
and firm pressure to the brake pedal to
slow the vehicle and reduce engine power.
If you experience this condition, apply the
brakes and bring your vehicle to a safe
stop. Switch the engine off, move the
transmission to park (P) and apply the
parking brake. Inspect the accelerator
pedal and the area around it for any items
or debris that may be obstructing its
movement. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.
Emergency Brake Assist
Emergency brake assist detects when you
brake heavily by measuring the rate at
which you press the brake pedal. It
provides maximum braking efficiency as
long as you press the pedal. Emergency
brake assist can reduce stopping distances
in critical situations. Note:
Depending on applicable laws and
regulations in the country for which your
vehicle was originally built, your brake lamps
could flash during heavy braking. Following
this, your hazard lights may also flash when
your vehicle comes to a stop.
Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking. This lamp momentarily
illuminates when you switch the
ignition on. If the light does not
illuminate during start up, remains on or
flashes, the anti-lock braking system may
be disabled. Have the system checked by
an authorized dealer. If the anti-lock brake
system is disabled, normal braking is still
effective.
See
Warning Lamps and Indicators
(page 85).
Note: Indicators vary depending on region. This lamp also illuminates
momentarily when you switch
the ignition on to confirm the
lamp is functional. If it does not
illuminate when you switch the
ignition on, or begins to flash at
any time, have the system checked by an
authorized dealer. If the brake warning
lamp illuminates with the parking brake
released, have the system checked
immediately.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
The anti-lock braking system does not
eliminate the risks when:
• You drive too closely to the vehicle in
front of you.
• Your vehicle is hydroplaning.
154
Mustang (CZG) Canada/United States of America, Vehicles Built From: 15-07-2019, enUSA, Edition date: 201906, Second-Printing Brakes E270480

•
You take corners too fast.
• The road surface is poor.
Note: If the system activates, the brake
pedal may pulse and may travel further.
Maintain pressure on the brake pedal. You
may also hear a noise from the system. This
is normal.
