2013 FORD F750 check engine

WARNING:Driving a vehicle with the brake system warning
light on is dangerous. A significant decrease in braking
performance may occur. It takes you longer to stop the vehicle. Have
the vehicle checked by your authorized dealer. Driving extended
distances with the parking brake engaged can cause brake failure and
the risk of personal injury.
Charging System
It illuminates when the 12–volt battery is not charging properly.
Contact your authorized dealer as soon as possible. This
indicates a problem with the electrical system or a related
component.
Check Fuel Cap (gasoline engine only)
It illuminates when the fuel cap may not be properly installed.
Continued driving with this light on may cause the service
engine soon warning indicator to come on.

It illuminates when the air suspension dump switch has been
activated.
Check Transmission (Allison automatic transmission only)
It illuminates while driving if a problem has been detected in
the transmission; shifting may be restricted. Depending on the
severity of the problem, the shifter’s digital read-out may turn
blank.
On MD 3000 series transmissions,operation may continue in order to
reach service assistance. The control unit may not respond to shift
selector requests, since operating limitations are being placed on the
transmission (i.e. upshifts and downshifts may be restricted). Direction
changes do not occur.

diagnostics system (OBD-II) has detected a malfunction.
WARNING:Under engine misfire conditions, excessive exhaust
temperatures could damage the catalytic converter, the fuel
system, interior floor coverings or other vehicle components, possibly
causing a fire.

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 five miles (eight kilometers)
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.
The powertrain control system meets all Canadian interference-causing
equipment standard requirements regulating the impulse electrical field
strength of radio noise.
When starting your vehicle, avoid pressing the accelerator pedal before
and during operation. Only use the accelerator pedal when you have
difficulty starting the engine.
If your vehicle is operated in a heavy snow storm or blowing snow
conditions, the engine air induction may become partially clogged with
snow or ice. If this occurs, the engine may experience a significant
reduction in power output. At the earliest opportunity, clear all the snow
or ice away from the air induction inlet.

operate while the engine is not running.
B.Lock:Locks the automatic transmission gearshift lever, if equipped
with positionP,and allows key removal.
C.Off:Shuts off the engine and all accessories.
D.On:All electrical circuits are operational. Warning lights are
illuminated. Key position when driving.
E.Start:Cranks the engine. Release the key as soon as the engine
starts.
STARTING A GASOLINE ENGINE
When the engine starts, the idle RPM runs faster to warm the engine. If
the engine idle speed does not slow down automatically, have the vehicle
checked.
Before starting the vehicle:
•Make sure all occupants buckle their safety belts.
•Make sure the headlamps and electrical accessories are off.
•Make sure the parking brake is set.
•Make sure the gearshift is in positionP.
•Turn the key to on without turning the key to start.

2. Turn the key to start the engine. The engine may continue cranking
for up to 15 seconds or until the vehicle starts.
Note:If the engine does not start on the first try, wait for a short period
of time and try again.
If you have difficulty starting the engine when the temperature is below
-13°F (-25°C), press the accelerator pedal slightly and try again.
If the engine does not start after three attempts, wait 10 seconds and
follow this flooded engine procedure.
1. Select positionPorN.
2. Fully press the accelerator pedal and hold it there.
3. Fully press the brake pedal.
4. Start 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 centimeters).
•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).
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 suitable for use 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 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 driving
your vehicle. Make sure the protective cover seals the prongs of the
block heater cord plug when not in use.

•Keep plug terminals clean and free of dirt and corrosion.
•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.
