2015 FORD F750 warning

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: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.

Diesel Engine
WARNING:Using low sulfur (16-500 ppm) or high sulfur
(greater than 500 ppm) diesel fuel in a diesel engine designed to
use only Ultra Low Sulfur Diesel fuel causes certain emission
components to malfunction which may also cause the Service Engine
Soon light to illuminate indicating an emissions-related concern. It may
also increase the likelihood of engine oil dilution with fuel which may
lead to major engine damage
WARNING:Do not mix diesel fuel with gasoline, gasohol or
alcohol. This could cause an explosion resulting in personal
injury.
WARNING:Do not add gasoline, gasohol or alcohol to diesel
fuel. This practice creates a serious fire hazard resulting in
personal injury and engine performance problems.
WARNING:Do not use starting fluid such as ether or gasoline.
Such fluids can cause immediate explosive damage to the engine
and possible personal injury.
WARNING:Do not use home heating oil or any diesel fuel not
intended for highway use. Red dye is used to identify fuels
intended for agricultural and non-highway use. Damage to the fuel
injection system, engine and exhaust catalyst can occur if an improper
fuel is used.
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 Ultra Low Sulfur (15 ppm Sulfur Maximum) No. 1-D or 2-D
diesel fuel in your diesel engine. Diesel fuel No. 1-D or winter diesel fuel
blend of No. 2-D is recommended at ambient temperatures below 20°F
(-7°C). Diesel fuel that is blended with 20% biodiesel maximum may be
used.

If you have run out of fuel:
•If your vehicle is equipped with dual fuel tanks, adding four–five
gallons (15–19 liters) of fuel is enough to restart the engine. If your
vehicle is out of fuel and on a steep grade, more than four–five
gallons (15–19 liters) may be required.
•The fuel system must be primed before attempting to restart the
engine. See your engine operator’s manual for instructions on priming
the engine.
•Use caution not to overheat and damage the starter by cranking the
engine for an excessive period. You may need to crank the engine for
a longer time than normal. If the engine fails to start in 30 seconds,
turn the ignition to the off position and wait for two minutes before
cranking the engine again.
•Any remaining trapped air self-purges from the fuel system once the
engine starts running.
•The engine may run rough and produce white smoke while air is in
the fuel system. This is normal and should stop after a short period.
SeeGeneral informationin theInformation Displayschapter for
information on Miles to Empty.
REFUELING
WARNING:Fuel vapor burns violently and a fuel fire can cause
severe injuries. To help avoid injuries to you and others:
•Read and follow all the instructions on the pump island.
•Turn off your engine when you are refueling.
•Do not smoke if you are near fuel or refueling your vehicle.
•Keep sparks, flames and smoking materials away from fuel.
•Stay outside your vehicle and do not leave the fuel pump unattended
when refueling your vehicle - this is against the law in some places.
•Keep children away from the fuel pump; never let children pump
fuel.
•Do not use personal electronic devices while refueling.
Use the following guidelines to avoid electrostatic charge build-up when
filling an ungrounded fuel container:
•Place approved fuel container on the ground.
•DO NOT fill a fuel container while it is in the vehicle (including the
cargo area).

•Keep the fuel pump nozzle in contact with the fuel container while
filling.
•DO NOT use a device that would hold the fuel pump handle in the fill
position.
Fuel Filler Cap
WARNING:The fuel system may be under pressure. If the fuel
filler cap is venting vapor or if you hear a hissing sound, wait
until it stops before completely removing the fuel filler cap. Otherwise,
fuel may spray out and injure you or others.
WARNING:If you do not use the proper fuel filler cap, excessive
pressure or vacuum in the fuel tank may damage the fuel system
or cause the fuel cap to disengage in a crash, which may result in
possible personal injury.
Note:If you must replace the fuel filler cap, replace it with a fuel filler
cap designed for your vehicle. The customer warranty may be void for
any damage to the fuel tank or fuel system if the correct genuine Ford,
Motorcraft or other certified fuel filler cap is not used.
Your fuel tank filler cap has an indexed design with a quarter–turn on
and off feature. When fueling your vehicle:
1. Turn the engine off.
2. Carefully turn the filler cap counterclockwise until it spins off.
3. Pull to remove the cap from the fuel filler pipe.
4. To install the cap, align the tabs on the cap with the notches on the
filler pipe.
5. Turn the filler cap clockwise a
14–turn until it clicks at least once.
If the check fuel cap light appears in the instrument cluster and stays on
after you start the engine, you not have installed the fuel filler cap
properly.
If the fuel cap light remains on, at the next opportunity, safely pull off
the road, remove the fuel filler cap, align the cap properly and reinstall
it. The check fuel cap light may not reset immediately; it may take
several driving cycles for the indicators to turn off. A driving cycle
consists of an engine start-up (after four or more hours with the engine
off) followed by normal city and highway driving.
108Fuel and Refueling
2015 F-650/750(f67)
Owners Guide gf(ownloose), 1st Printing, December 2013

Keep a record for at least one month and record the type of driving (city
or highway). This provides an accurate estimate of your vehicle’s fuel
economy under current driving conditions. Additionally, keeping records
during summer and winter shows how temperature impacts fuel
economy. In general, lower temperatures mean lower fuel economy.
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, you must maintain the
DEF level. Generally, you should fill the DEF tank before the DEF gauge
in the instrument cluster reaches the first low level warning (see
Warning 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 you refill the DEF tank, 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 1 gallon (3.8 liters) in the 5-gallon
(19.0 liters) DEF tank or 2 gallons (7.6 liters) in the 10-gallon
(34.0 liters) DEF tank.
Upon filling the DEF tank after a low-level warning, normal operation
resumes when you restart your vehicle.
