warning lights FORD F750 2013 12.G Owners Manual

Trailer
If you are pulling a trailer, an inspection of the trailer similar to that of
the tractor should be done. The inspection should follow trailer
manufacturer recommendations and should include at a minimum:
general condition, landing gear, doors, sides, lights, reflectors,
suspension, brakes, tires, wheels, cargo placement, stability and
tie-downs.
Transmission
WARNING:If the unit starts in gear and/or the neutral start
switch is not functioning correctly, the vehicle may inadvertently
move which could result in property damage, personal injury or death.
If your vehicle is equipped with an automatic transmission, regularly
inspect the transmission’s neutral start switch. The engine should only
start in positionNorP.
Inspect the transmission fluid level and shift linkage for proper
operation.

REAR SEAT ARMREST (IF EQUIPPED)
To use the armrest, rotate it
forward from the seat back.
HEATED SEATS (IF EQUIPPED)
WARNING:Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes, spinal cord
injury, medication, alcohol use, exhaustion, or other physical conditions,
must exercise care when using the seat heater. The seat heater may
cause burns even at low temperatures, especially if used for long
periods of time. Do not place anything on the seat that insulates against
heat, such as a blanket or cushion, because this may cause the seat
heater to overheat. Do not puncture the seat with pins, needles, or
other pointed objects because this may damage the heating element
which may cause the seat heater to overheat. An overheated seat may
cause serious personal injury.
Note:Do not do the following:
•Place heavy objects on the seat.
•Operate the seat heater if water or any other liquid is spilled on the
seat. Allow the seat to dry thoroughly.
•Operate the heated seats unless the engine is running. Doing so could
drain your vehicle’s battery.
Press to cycle through the various heat settings and off.
Warmer settings are indicated by more indicator lights.

IGNITION SWITCH
Note:When you switch the ignition off and leave your vehicle, do not
leave your key in the ignition. This could discharge your vehicle battery.
A.Accessory:Allows the electrical accessories, such as the radio, to
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.
Some warning lights briefly illuminate.
Note:Do not touch the accelerator pedal.
1. Fully press the brake pedal.

SELECTIVE CATALYTIC REDUCTION (SCR) SYSTEM (DIESEL
ENGINE ONLY)
Your vehicle is equipped with a selective catalytic reduction (SCR)
system to help reduce emission levels of oxides of nitrogen from the
exhaust of the diesel engine. The system automatically injects diesel
exhaust fluid (DEF) into the exhaust system to enable proper SCR
function.
Importance of Maintaining the DEF Level
In order for the SCR system to operate properly, the DEF level must be
maintained. Generally, the DEF tank should be filled before the DEF
gauge in the instrument cluster reaches the first low level warning
(seeWarning messages and vehicle operations).
The engine control unit monitors the amount of fluid available in the
DEF tank. Failure to maintain an adequate amount of DEF in the system
generates warning messages that appear in the information display and,
unless the DEF tank is refilled, leads to a forced reduction of engine
operations.
Warning Messages and Vehicle Operations
The instrument cluster contains a DEF gauge and indicator lights to alert
you to any low DEF level conditions. The indicator lights illuminate if the
DEF gauge level drops below 0.5 gallons (1.9 liters) in the 5 gallon
(19.0 liters) DEF tank or 1 gallon (3.8 liters) in the 9 gallon (34.0 liters)
DEF tank.
Upon filling the DEF tank after a low level warning, normal operation
resumes when the vehicle is restarted.

Trailer Lamps
WARNING:Never connect any trailer lamp wiring to the
vehicle’s tail lamp wiring; this may damage the electrical system
resulting in a fire. Contact an authorized dealer as soon as possible for
assistance in proper trailer tow wiring installation. Additional electrical
equipment may be required.
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working.
Before Towing a Trailer
Practice turning, stopping and backing up to get the feel of your
vehicle-trailer combination before starting on a trip. When turning, make
wider turns so the trailer wheels clear curbs and other obstacles.
When Towing a Trailer
•Check your hitch, electrical connections and trailer wheel lug nuts
thoroughly after you have traveled 50 miles (80 kilometers).
•Place the gearshift lever in positionP(if equipped) or neutral to aid
in engine and transmission cooling and A/C efficiency during hot
weather while stopped in traffic.
•Turn off the speed control. The speed control may turn off
automatically when you are towing on long, steep grades.
•Shift to a lower gear when driving down a long or steep hill. Do not
apply the brakes continuously, as they may overheat and become less
effective.
•Allow more distance for stopping with a trailer attached. Anticipate
stops and brake gradually.
FIFTH-WHEEL OPERATION
WARNING:Failure to follow the fifth-wheel manufacturer’s
instructions for hooking and unhooking as well as sliding the
fifth-wheel could result in an accident, personal injury or death.
WARNING:When the tractor and trailer are parked unattended,
the trailer brake hand control should never be used to apply the
brake, since air may leak from the system, allowing vehicle movement,
resulting in possible property damage, personal injury or death.

WARNING:The use of inferior parts can adversely affect the
quality and reliability of your vehicle which, in turn, can result in
property damage, personal injury or death.
To avoid damage to the vehicle’s electrical components prior to electric
welding:
•disconnect both battery cables.
•attach the welder ground cable as close as possible to the part being
welded.
•it is recommended that the component be temporarily removed if
welding close to an electrical component.
Follow the checks and services in theScheduled Maintenancechapter.
Have your dealer or service center inspect your vehicle at least once a
year. Remember that regular maintenance and inspections usually
prevent serious problems from developing later.
If the owner or operator of the vehicle is a skilled technician and intends
on performing the vehicle maintenance and service, he is strongly urged
to purchase a service manual.
Electrical System
Periodically inspect electrical connectors on the outside of the cab and
on the engine and frame for corrosion and tightness. Exposed terminals,
such as the fuel sender, cranking motor, alternator and feed-through
studs, should be cleaned and re-coated with a lubricant sealing grease
such as Motorcraft® Silicone Brake Caliper Grease and Dielectic
Compound XG-3, or equivalent. This should include the ground cable
connector for batteries, engine and cab as well as the jump starting stud.
Accessory Feed Connections
Vehicle electrical systems are complex and often include powertrain
components, such as engine and transmission controls, instrument
panels, ABS, etc. While most systems operate on battery voltage
(12 volts), some systems can be as high as 90 volts or as low as five
volts. See theElectrical Circuit Diagram Manuals,available from your
vehicle’s manufacturer, to make sure that any additional body lights and
accessories are connected to circuits that are both appropriate and not
overloaded. No modification should be made to any vehicle control
system without first contacting your dealer.
