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.

•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 of time. 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 of
time.
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.

GENERAL INFORMATION
All standard equipment brakes are designed to be self-adjusting.
Automatic adjustment, when required, occurs whenever the brakes are
applied and released during forward or reverse operation.
Note:Occasional brake noise is normal. If a metal-to-metal, continuous
grinding or continuous squeal sound is present, the brake linings may be
worn out and should be inspected by an authorized dealer. If the vehicle
has continuous vibration or shudder in the steering wheel while braking,
the vehicle should be inspected by an authorized dealer.
Know the required stopping distances for all driving conditions that may
be encountered. For longer brake lining life, take full advantage of engine
braking power when coming to a stop.
WARNING:Do not drive with your foot resting on the brake
pedal. This results in abnormally high brake temperatures,
excessive lining wear and increased stopping distances.
Before descending a long or steep hill, shift to a lower gear and avoid
continuous application of the brakes. Normally, choose the same gear to
descend the hill that you use to ascend the hill.
WARNING:Continuous application of the brakes causes the
brakes to overheat, resulting in a temporary loss of braking.
See theInstrument Clusterchapter for information on the
brake system warning light.
Wet brakes result in reduced braking efficiency. Gently press the brake
pedal a few times when driving from a car wash or standing water to dry
the brakes.
If Brakes Do Not Grip Well
•If you have been driving through deep water, gently apply the brakes
several times while the vehicle is moving slowly.
•Let the brakes cool if you have been using them excessively, as in
mountain driving or after several fast, high-speed stops.
•Check brake adjustment.
•Check brake linings for excessive wear.
•Check system air pressure on vehicles equipped with air brakes.

Hot Weather
•Use a permanent-type engine coolant to protect the engine against
damage from overheating.
•Fill the fuel tank at the end of daily operation to prevent
condensation in the fuel system.
•Keep external surfaces of the engine, radiator, charge air cooler, A/C
condenser and accessories clean to avoid dirt build-up.
•Above normal coolant temperatures could be experienced while
driving in a transmission gear ratio which lugs the engine. To correct
this problem, engine speed should be increased by downshifting into
the next lower gear.
STEERING
Your vehicle is equipped with power steering. Power steering uses energy
from the engine to decrease the driver’s effort in steering the vehicle.
To help prevent damage to the power steering pump:
•Never hold the steering wheel to the extreme right or the extreme
left for more than a few seconds when the engine is running.
•Do not operate the vehicle with the power steering pump fluid level
below the ADD mark on the MAX. COLD side of the power steering
reservoir dipstick.
•Some noise is normal during operation. If the noise is excessive,
check for low power steering pump fluid level before seeking service
by your authorized dealer.
•Heavy or uneven steering efforts may be caused by low power
steering pump fluid level. Check for low power steering pump fluid
level before seeking service by your authorized dealer.
•Do not fill the power steering pump reservoir above the FULL mark
on the MAX. HOT side of the power steering reservoir dipstick, as
this may result in leaks from the reservoir.
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
•underinflated tire(s) on any wheel(s)
•uneven vehicle loading
•high crown in center of road
•high crosswinds
•wheels out of alignment
•loose or worn suspension components.

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.

•In case of emergency, a large amount of water without engine coolant
may be added in order to reach a vehicle service location. In this
instance, the cooling system must be drained, chemically cleaned with
Motorcraft® Premium Cooling System Flush, and refilled with prediluted
engine coolant as soon as possible. Water alone (without engine coolant)
can cause engine damage from corrosion, overheating or freezing.
•Do not use alcohol, methanol, brine or any engine coolants mixed with
alcohol or methanol antifreeze (coolant). Alcohol and other liquids can
cause engine damage from overheating or freezing.
•Do not add extra inhibitors or additives to the coolant. These can be
harmful and compromise the corrosion protection of the engine coolant.
Unscrew the cap slowly. Any pressure escapes as you unscrew the cap.
Add prediluted engine coolant meeting the Ford specification.
SeeCapacities and Specificationsfor more information.
Whenever coolant has been added, the coolant level in the coolant
reservoir should be checked the next few times you drive the vehicle.
If necessary, add enough prediluted engine coolant to bring the coolant
level to the proper level.
Recycled Engine Coolant
Ford Motor Company does not recommend the use of recycled engine
coolant since a Ford-approved recycling process is not yet available.
Always dispose of used automotive fluids in a responsible manner. Follow
your community’s regulations and standards for recycling and disposing
of automotive fluids.
Severe Climates
If you drive in extremely cold climates:
•It may be necessary to have a Ford authorized dealer increase the
coolant concentration above 50%.
•A coolant concentration of 60% provides improved freeze point
protection. Engine coolant concentrations above 60% decrease the
overheat protection characteristics of the engine coolant and may
cause engine damage.
If you drive in extremely hot climates:
•It may be necessary to have a Ford authorized dealer decrease the
coolant concentration to 40%.
•A coolant concentration of 40% provides improved overheat
protection. Engine coolant concentrations below 40% decrease the
corrosion and freeze protection characteristics of the engine coolant
and may cause engine damage.
Maintenance221
2013 F-650/750(f67)
Owners Guide gf, 2nd Printing, March 2013

Vehicles driven year-round in non-extreme climates should use
prediluted engine coolant for optimum cooling system and engine
protection.
What You Should Know About Fail-Safe Cooling (If Equipped)
(Gasoline Engine Only)
WARNING:If fail-safe cooling activates, pull off the road as soon
as safely possible and turn the engine off. The engine may
automatically shut off while driving without further indication.
If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily before incremental component damage is incurred.
The fail-safe distance depends on ambient temperatures, vehicle load and
terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat:
•The engine coolant temperature gauge moves to the red (hot) area.
•The information display indicates the engine is overheating.
•The service engine soon indicator illuminates.
If the engine reaches a preset over-temperature condition, the engine
automatically switches to alternating cylinder operation. Each disabled
cylinder acts as an air pump and cools the engine.
When Fail-Safe Mode Is Activated
WARNING:Never remove the coolant reservoir cap while the
engine is running or hot.
Note:Driving the vehicle without repairing the engine problem increases
the chance of engine damage. Take your vehicle to an authorized dealer
as soon as possible.
You have limited engine power when in the fail-safe mode, so drive the
vehicle with caution. The vehicle is not able to maintain high-speed
operation and the engine runs rough. Remember that the engine is
capable of completely shutting down automatically to prevent engine
damage; therefore:
1. Pull off the road as soon as safely possible and turn off the engine.
2. Arrange for the vehicle to be taken to an authorized dealer.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and replenish if low.
5. Restart the engine and take your vehicle to an authorized dealer.

Additives and Chemicals
This owner’s manual and the Ford Workshop Manual list the
recommended additives and chemicals for your vehicle. We do not
recommend using chemicals or additives not approved by us as part of
your vehicle’s normal maintenance. Please consult your warranty
information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a normal operating characteristic
and, by itself, does not necessarily indicate a concern or that the fluid
needs to be changed. However, a qualified expert, such as the
factory-trained technicians at your dealership, should inspect discolored
fluids that also show signs of overheating or foreign material
contamination immediately.
Make sure to change your vehicle’s oils and fluids at the specified
intervals or in conjunction with a repair. Flushing is a viable way to
change fluid for many vehicle sub-systems during scheduled
maintenance. It is critical that systems are flushed only with new fluid
that is the same as that required to fill and operate the system or using a
Ford-approved flushing chemical.
Owner Checks and Services
Certain basic maintenance checks and inspections should be performed
monthly or at six month intervals.
