GENERAL INFORMATION
WARNING:Extended idling at high engine speeds can produce
very high temperatures in the engine and exhaust system,
creating the risk of fire or other damage.
WARNING:Do not park, idle, or drive your vehicle on dry grass
or other dry ground cover. The emission system heats up the
engine compartment and exhaust system, which can start a fire.
WARNING:Do not start your vehicle in a closed garage or in
other enclosed areas. Exhaust fumes can be toxic. Always open
the garage door before you start the engine.
WARNING:If you smell exhaust fumes inside your vehicle, have
your vehicle checked by an authorized dealer immediately. Do not
drive if you smell exhaust fumes.
If you disconnect the battery, your vehicle may exhibit some unusual
driving characteristics for approximately 5 miles (8 km) after you
connect it. This is because the engine management system must realign
itself with the engine. You may disregard any unusual driving
characteristics during this period.
This system meets all Canadian interference-causing equipment standard
requirements regulating the impulse electrical field strength of radio
noise.
When starting your engine, avoid pressing the accelerator pedal before
and during operation. Only use the accelerator pedal when you have
difficulty starting the engine.

Guarding Against Exhaust Fumes
WARNING:If you smell exhaust fumes inside your vehicle, have
this checked immediately. Do not drive your vehicle if you smell
exhaust fumes. Carbon monoxide is present in exhaust fumes. Take
precautions to avoid its dangerous effects.
Important Ventilating Information
If you stop your vehicle and leave the engine idling for long periods of
time, we recommend that you do one of the following:
•Open the windows at least 1 inch (2.5 cm).
•Set your climate control to outside air.
ENGINE BLOCK HEATER (IF EQUIPPED)
WARNING:Failure to follow engine block heater instructions
could result in property damage or physical injury.
WARNING:Do not use your heater with ungrounded electrical
systems or two-pronged (cheater) adapters. There is a risk of
electrical shock.
Note:The heater is most effective when outdoor temperatures are below
0°F (-18°C).
154Starting and Stopping the Engine

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 A/C
electrical source.
We recommend that you do the following for safe and correct operation:
•Use a 16-gauge outdoor extension cord that is product certified by
Underwriter’s Laboratory or Canadian Standards Association. This
extension cord must be able to be used outdoors, in cold
temperatures, and be clearly markedSuitable for Use with Outdoor
Appliances. Never use an indoor extension cord outdoors; it 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 the
heater cord plug connections are free and clear of water. This could
cause an electric shock or fire.
•Make sure the 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 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 will achieve maximum temperature
after approximately three hours of operation. If you use the heater longer
than three hours, this will not improve system performance and will use
unnecessary 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 door (Easy Fuel“no cap” fuel
system), do not refuel until the sound stops. Otherwise, fuel may spray
out, which could cause serious personal injury.
WARNING:Automotive fuels can cause serious injury or death if
misused or mishandled.
WARNING:The flow of fuel through a fuel pump nozzle can
produce static electricity, which can cause a fire if fuel is pumped
into an ungrounded fuel container.
WARNING:Fuel ethanol and gasoline 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 filler neck. Never smoke
while refueling. Fuel vapor is extremely hazardous under certain
conditions. Care should be taken to avoid inhaling excess fumes.
Observe the following guidelines when handling automotive fuel:
•Extinguish all smoking materials and any open flames before refueling
your vehicle.
•Always turn off the vehicle before refueling.
•Automotive fuels can be harmful or fatal if swallowed. Fuel such as
gasoline is highly toxic and if swallowed can cause death or permanent
injury. If fuel is swallowed, call a physician immediately, even if no
symptoms are immediately apparent. The toxic effects of fuel may not
be visible for hours.
•Avoid inhaling fuel vapors. Inhaling too much fuel vapor of any kind
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.
156Fuel and Refueling
2013 05+ Mustang(197)

•Avoid getting fuel liquid in your eyes. If fuel is splashed in the eyes,
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 also be harmful if absorbed through the skin. If fuel is
splashed on the skin and/or clothing, promptly remove contaminated
clothing and wash skin thoroughly with soap and water. Repeated or
prolonged skin contact with fuel liquid or vapor causes skin irritation.
•Be particularly careful if you are taking “Antabuse” or other forms of
disulfiram for the treatment of alcoholism. Breathing gasoline vapors,
or skin contact could cause an adverse reaction. In sensitive
individuals, serious personal injury or sickness may result. If fuel is
splashed on the skin, promptly wash skin thoroughly with soap and
water. Consult a physician immediately if you experience an adverse
reaction.
FUEL QUALITY
Choosing the Right Fuel
Note:Use of any fuel other than those recommended may cause
powertrain damage, a loss of vehicle performance, and repairs may not
be covered under warranty.
Use only UNLEADED fuel or UNLEADED fuel blended with a maximum
of 15% ethanol. Do not use fuel ethanol (E85), diesel, fuel methanol,
leaded fuel or any other fuel because it could damage or impair the
emission control system. The use of leaded fuel is prohibited by law.
Your vehicle was not designed to use fuel or fuel additives with metallic
compounds, including manganese-based additives.
Octane Recommendations
•3.7L V6 engine
“Regular” unleaded gasoline with a pump (R+M)/2 octane rating of 87 is
recommended. Some stations offer fuels posted as “Regular” with an
octane rating below 87, particularly in high altitude areas. Fuels with
octane levels below 87 are not recommended.
