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

WARNING: Do not use your heater
with ungrounded electrical systems or
two-pronged adapters. There is a risk of
electrical shock. WARNING: Do not fully close the
hood, or allow it to drop under its own
weight when using the engine block
heater. This could damage the power
cable and may cause an electrical short
resulting in fire, injury and property
damage.
Note: The heater is most effective when
outdoor temperatures are below
0°F
(-18°C).
The heater acts as a starting aid by
warming the engine coolant. This allows
the climate control system to respond
quickly. The equipment includes a heater
element, installed in the engine block and
a wire harness. You can connect the
system to a grounded 120-volt AC
electrical source.
We recommend that you do the following
for a safe and correct operation:
• Use a 16-gauge outdoor extension cord
that is product certified by
Underwriter ’s Laboratory (UL) or
Canadian Standards Association
(CSA). This extension cord must be
suitable for use outdoors, in cold
temperatures, and be clearly marked
Suitable for Use with Outdoor
Appliances. Do not use an indoor
extension cord outdoors. This could
result in an electric shock or become a
fire hazard.
• Use as short an extension cord as
possible.
• Do not use multiple extension cords. •
Make sure that when in operation, the
extension cord plug and heater cord
plug connections are free and clear of
water. This could cause an electric
shock or fire.
• If the block heater cord is under the
hood, Do Not remove the wiring from
its original location. Do Not close the
hood on the extension wiring.
• Make sure your vehicle is parked in a
clean area, clear of combustibles.
• Make sure the heater, heater cord and
extension cord are firmly connected.
• Check for heat anywhere in the
electrical hookup once the system has
been operating for approximately 30
minutes.
• Make sure the system is unplugged and
properly stowed before starting and
driving your vehicle. Make sure the
protective cover seals the prongs of the
block heater cord plug when not in use.
• Make sure the heater system is
checked for proper operation before
winter.
Using the Engine Block Heater
Make sure the receptacle terminals are
clean and dry prior to use. Clean them with
a dry cloth if necessary.
The heater uses 0.4 to 1.0 kilowatt-hours
of energy per hour of use. The system does
not have a thermostat. It achieves
maximum temperature after
approximately three hours of operation.
Using the heater longer than three hours
does not improve system performance and
unnecessarily uses electricity.

SAFETY PRECAUTIONS
WARNING: Do not overfill the fuel
tank. The pressure in an overfilled tank
may cause leakage and lead to fuel spray
and fire. WARNING:
The fuel system may
be under pressure. If you hear a hissing
sound near the fuel filler inlet, do not
refuel until the sound stops. Otherwise,
fuel may spray out, which could cause
serious personal injury. WARNING: Fuels can cause serious
injury or death if misused or mishandled. WARNING:
Fuel may contain
benzene, which is a cancer-causing
agent. WARNING: When refueling always
shut the engine off and never allow
sparks or open flames near the fuel tank
filler valve. Never smoke or use a cell
phone while refueling. Fuel vapor is
extremely hazardous under certain
conditions. Avoid inhaling excess fumes.
Follow these guidelines when refueling:
• Extinguish all smoking materials and
any open flames before refueling your
vehicle.
• Always switch the engine off before
refueling.
• Automotive fuels can be harmful or
fatal if swallowed. Fuel is highly toxic
and if swallowed can cause death or
permanent injury. If fuel is swallowed
immediately call a physician, even if no
symptoms are immediately apparent.
The toxic effects of fuel may not be
apparent for hours. •
Avoid inhaling fuel vapors. Inhaling fuel
vapor can lead to eye and respiratory
tract irritation. In severe cases,
excessive or prolonged breathing of
fuel vapor can cause serious illness and
permanent injury.
• Avoid getting fuel in your eyes. If you
splash fuel in your eyes, immediately
remove contact lenses (if worn), flush
with water for 15 minutes and seek
medical attention. Failure to seek
proper medical attention could lead to
permanent injury.
• Fuels can be harmful if absorbed
through the skin. If you splash fuel on
your skin, clothing or both, promptly
remove contaminated clothing and
thoroughly wash your skin with soap
and water. Repeated or prolonged skin
contact causes skin irritation.
• Be particularly careful if you are taking
Antabuse or other forms of Disulfiram
for the treatment of alcoholism.
Breathing fuel vapors could cause an
adverse reaction, serious personal
injury or sickness. Immediately call a
physician if you experience any adverse
reactions.
FUEL QUALITY
Choosing the Right Fuel Your vehicle is designed to operate on
regular unleaded gasoline with a minimum
pump (R+M)/2 octane rating of 87.
136
Mustang (CZG) Canada/United States of America, Vehicles Built From: 15-07-2019, enUSA, Edition date: 201906, Second-Printing Fuel and RefuelingE161513

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.
137
Mustang (CZG) Canada/United States of America, Vehicles Built From: 15-07-2019, enUSA, Edition date: 201906, Second-Printing Fuel and Refueling

Use the following guidelines to avoid
electrostatic charge build-up, which can
produce a spark, when filling an
ungrounded fuel container:
•
Only use an approved fuel container to
transfer fuel to your vehicle. Place the
container on the ground when filling it.
• Do not fill a fuel container when it is
inside your vehicle (including the cargo
area).
• Keep the fuel pump nozzle in contact
with the fuel container when filling it.
• Do not use a device that holds the fuel
pump nozzle lever in the fill position.
Adding Fuel From a Portable Fuel
Container WARNING: Do not insert the nozzle
of a fuel container or an aftermarket
funnel into the fuel filler neck. This may
damage the fuel system filler neck or its
seal and cause fuel to run onto the
ground. WARNING: Do not try to pry open
or push open the capless fuel system
with foreign objects. This could damage
the fuel system and its seal and cause
injury to you or others. WARNING:
Do not dispose of fuel
in the household refuse or the public
sewage system. Use an authorized waste
disposal facility.
When refueling the vehicle fuel tank from
a fuel container, use the fuel filler funnel
included with your vehicle. See Fuel Filler
Funnel Location
(page 137).
Note: Do not use aftermarket funnels as
they may not work with the capless fuel
system and can damage it.
When refueling the vehicle fuel tank from
a fuel container, do the following: 1. Fully open the fuel filler door.
2.
Fully insert the fuel filler funnel into the
fuel filler inlet. 3. Add fuel to your vehicle from the fuel
container.
