2015 FORD SUPER DUTY lights

Turn on the headlights. If the lights are dim,
do not go on at all or when the ignition is
turned to START the lights become dim or
go out, the battery connections may be
loose or corroded, or the battery may be
discharged. If there is a clicking or
stuttering sound coming from the engine
compartment when you turn the key to
START, this may also indicate a loose or
corroded battery connection.
Check the battery connections at the
battery posts, cable connection to the
engine grounding point and at the starter
connection.
If you suspect a discharged battery, have
it checked and corrected.
•
The gearshift lever must be in P (Park)
or N (Neutral) in order for the starter
to operate.
• Try operating the starter switch several
times. This operation may clean
potentially corroded contacts or make
the switch temporarily operable until
you can reach the dealer.
• If all electrical connections are tight
and you need assistance to start, refer
to Jump Starting in the Roadside
Emergencies chapter of your Owner ’s
Manual.
If engine cranks but won ’t start
Prolonged starter cranking (in excess of 10
seconds) could cause damage to the
starter motor or the high-pressure fuel
pump. •
Check the fuel gauge. You may be out
of fuel. If the gauge shows that there
is fuel in the tank, the trouble may be
in the electrical system or the fuel
system. If equipped with an auxiliary
tank, be sure that the tank control
switch is set for the tank with fuel and
not on an empty tank.
• Leaving your ignition key turned to on
for over two minutes without starting
may make starting difficult because
the glow plugs will cease activation.
Reset the system by turning the ignition
key to off and then back to on again.
Note: If the system is out of fuel and the
engine will not start, do not continue
cranking the engine. Continued cranking can
damage the high-pressure fuel pump.

The following could cause the engine to
overheat:
• Lack of coolant
• Dirty cooling system.
• Plugged radiator fins, A/C condenser
and/or oil cooler
• Malfunctioning fan drive
• Driving with frozen coolant
• Sticking thermostat
• Overloading or pulling heavy trailers
during hot weather

Diesel Exhaust Fluid (DEF) (If
Equipped) With the key in the on position,
lights when the DEF is
contaminated or low. See
Selective Catalytic Reduction System
(page
21).
Glow Plug Pre-Heat With the key in the on position,

is necessary as a starting aid.
Wait until the light goes off before starting.
See
Starting a Diesel Engine (page 10).
After you start the engine, the light should
turn off. When the engine is cold, the light
should always light for a short period.
Water In Fuel During refueling, it is possible for
you to pump
water-contaminated diesel fuel
into your fuel tank. Your vehicle ’s fuel
system is equipped with a fuel filter and
water separator to remove water from the
fuel. The water in fuel indicator lights when
the fuel and water separator has a
significant quantity of water in it and
requires immediate draining.
If the water in fuel lights when the engine
is running, stop your vehicle as soon as
safely possible, shut off the engine, then
drain the fuel and water separator. See
Fuel Quality
(page 15). Allowing water
to stay in the fuel system, after the water
in fuel indicator lights, could result in
extensive damage or failure of the fuel
injection system. WARNING
Do not drain the fuel and water
separator while the engine is running.
Fuel may ignite if the separator is
drained while the engine is running or the
vehicle is moving. Note:
Do not drain the fuel and water
separator while the engine is running. Air will
enter into the fuel system causing the engine
not to operate properly.
