• 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, See
Jump Starting the Vehicle (page 190).
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.
If the engine runs hot
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
• Grill or radiator air blockage
• Slipping or missing drive belt
• Plugged or very dirty air filter
If fuses burn out
WARNING: Replacement fuses and
circuit breakers must always be the
same rating as the original equipment
shown. Never replace a fuse or circuit
breaker with one of a higher rating.
Higher rated fuses or circuit breakers
could allow circuit overloading in the
event of a circuit malfunction, resulting
in severe vehicle damage or personal
injury due to fire.
Burned-out or blown fuses usually indicate
an electrical short-circuit, although a fuse
may occasionally burn out from vibration.
Insert a second fuse. If this fuse
immediately burns out and you cannot
locate the cause, return your vehicle to
your dealer for a circuit check. See
Changing a Fuse (page 208).
Selective catalytic reduction system
speed limit and Idle-only modes
If the vehicle’s speed is limited or in an
idle-only mode, the selective catalytic
reduction system may be limiting the
vehicle’s functions due to low or
contaminated DEF. Check the DEF. See
Selective Catalytic Reductant System
(page 118).

Do not use alcohol-based additives to
improve cetane quality, to prevent fuel
gelling or any other use. The use of alcohol
additives may result in damage to the fuel
injectors and system.
The Vehicle Warranty may not cover
repairs needed to correct the effects of
using an aftermarket product that does
not meet Ford specifications in your fuel.
FUEL QUALITY - GASOLINE
Choosing the Right Fuel
E161513E161513
Your vehicle is designed to operate on
regular unleaded gasoline with a minimum
pump (R+M)/2 octane rating of 87.
Some fuel stations, particularly those in
high altitude areas, offer fuels posted as
regular unleaded gasoline with an octane
rating below 87. The use of these fuels
could result in engine damage that will not
be covered by the vehicle warranty.
We do not recommend these fuels. For
best overall vehicle and engine
performance, premium fuel with an octane
rating of 91 or higher is recommended. The
performance gained by using premium fuel
is most noticeable in hot weather as well
as other conditions, for example when
towing a trailer. See Towing a Trailer
(page 178).Do not be concerned if the engine
sometimes knocks lightly. However, if the
engine knocks heavily while using fuel with
the recommended octane rating, contact
an authorized dealer to prevent any engine
damage.
We recommend Top Tier detergent
gasolines, where available to help minimize
engine deposits and maintain optimal
vehicle and engine performance. For
additional information, refer to
www.toptiergas.com.
Note:Use of any fuel for which the vehicle
was not designed can impair the emission
control system, cause loss of vehicle
performance, and cause damage to the
engine which may not be covered by the
vehicle Warranty.
Do not use:
• Diesel fuel.
• Fuels containing kerosene or paraffin.
• Fuel containing more than 10% ethanol
or E85 fuel.
• Fuels containing methanol.
• Fuels containing metallic-based
additives, including manganese-based
compounds.
• Fuels containing the octane booster
additive, methylcyclopentadienyl
manganese tricarbonyl (MMT).
• Leaded fuel, using leaded fuel is
prohibited by law.
The use of fuels with metallic compounds
such as methylcyclopentadienyl
manganese tricarbonyl (commonly known
as MMT), which is a manganese-based
fuel additive, will impair engine
performance and affect the emission
control system.

illuminates in the instrument cluster.The tow/haul feature:
• Delays upshifts to reduce the frequency
of transmission shifting.
• Provides engine braking in all forward
gears, which slows your vehicle and
assists you in controlling your vehicle
when descending a grade.
• Depending on driving and load
conditions, could downshift the
transmission to slow your vehicle and
help control your vehicle speed when
descending a hill, without pressing the
accelerator pedal. Tapping the brake
pedal downshifts the transmission to
provide additional braking, only if the
downshift does not cause an engine
overspeed condition.
The tow/haul feature improves
transmission operation when towing a
trailer or a heavy load. All transmission
gear ranges are available when using
tow/haul.
Note:Under certain conditions, the
automatic tow/haul feature engages, and
the TOW HAUL indicator illuminates
without pressing the tow/haul button.
To deactivate the tow/haul feature and
return to normal driving mode, press the
button on the gearshift lever twice. The
TOW HAUL indicator turns off. Tow/haul
also deactivates when you power down
your vehicle.
WARNING: Do not use tow/haul
when the road surface is slippery. Failure
to follow this instruction could result in
the loss of control of your vehicle.
WARNING: Do not use diesel
engine exhaust braking when the road
surface is slippery. Failure to follow this
