2013 FORD SUPER DUTY run flat

The airbags are a supplemental restraint system and are designed to
work with the safety belts to help protect the driver and right front
passenger from certain upper body injuries. Airbags do not inflate slowly;
there is a risk of injury from a deploying airbag.
Note:You will hear a loud bang and see a cloud of harmless powdery
residue if an airbag deploys. This is normal.
The airbags inflate and deflate rapidly upon activation. After airbag
deployment, it is normal to notice a smoke-like, powdery residue or smell
the burnt propellant. This may consist of cornstarch, talcum powder (to
lubricate the bag) or sodium compounds (for example, baking soda) that
result from the combustion process that inflates the airbag. Small
amounts of sodium hydroxide may be present which may irritate the skin
and eyes, but none of the residue is toxic. While the system is designed
to help reduce serious injuries, contact with a deploying airbag may also
cause abrasions or swelling. Temporary hearing loss is also a possibility
as a result of the noise associated with a deploying airbag. Because
airbags must inflate rapidly and with considerable force, there is the risk
of death or serious injuries, such as fractures, facial and eye injuries or
internal injuries, particularly to occupants who are not properly
restrained or are otherwise out of position at the time of airbag
deployment. Thus, it is extremely important that occupants be properly
restrained as far away from the airbag module as possible while
maintaining vehicle control.
Routine maintenance of the airbags is not required.
SOS POST-CRASH ALERT SYSTEM™
The system flashes the turn signal lamps and sounds the horn
(intermittently) in the event of a serious impact that deploys an airbag
equipped on your vehicle, such as front, side, side curtain or Safety
Canopy®.
The horn and lamps will turn off when:
•the hazard control button is pressed
•the panic button (if equipped) is pressed on the remote entry
transmitter, or
•your vehicle runs out of power.

Steering
To help prevent damage to the power steering system:
•Never hold the steering wheel at its furthest turning points (until it
stops) for more than three to five seconds when the engine is running.
•Do not operate the vehicle with a low power steering pump fluid level
(below the MIN mark on the reservoir).
•Some noise is normal during operation. If excessive, check for low
power steering pump fluid level before seeking service by your dealer.
•Heavy or uneven efforts may be caused by low power steering fluid.
Check for low power steering pump fluid level before seeking service
by your dealer.
•Do not fill the power steering pump reservoir above the MAX mark on
the reservoir, 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:
•an improperly inflated tire
•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper steering alignment
If any steering components are serviced or replaced, install new
fasteners (many are coated with thread adhesive or have prevailing
torque features which may not be re-used). Never re-use a bolt or nut.
Torque fasteners to specifications inWorkshop Manual.
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.

•Add particular accessories to your vehicle (e.g.; bug deflectors,
rollbars or light bars, running boards, ski racks).
•Drive with the wheels out of alignment.
Conditions
•Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
•Carrying unnecessary weight may reduce fuel economy (approximately
1 mpg [0.4 km/L] is lost for every 400 lb [180 kg] of weight carried).
•Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
•To maximize the fuel economy, drive with the tonneau cover installed
(if equipped).
•Using fuel blended with alcohol may lower fuel economy.
•Fuel economy may decrease with lower temperatures during the first
8–10 miles (12–16 km) of driving.
•Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
•Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
•Four-wheel-drive operation (if equipped) is less fuel efficient than
two-wheel-drive operation.
•Close windows for high speed driving.
DRIVING THROUGH WATER
Note:Driving through deep water may allow water into the transmission
and engine causing internal damage. Have the fluid checked and, if water
is found, replace the fluid.
Do not drive quickly through standing water, especially if the depth is
unknown. Traction or brake capability may be limited and if the ignition
system gets wet, your engine may stall. Water may also enter your
engine’s air intake and severely damage your engine.

•The Total Accessory Reserve Capacity (TARC) is shown on the lower
right side of the vehicle’s Safety Compliance Certification Label. This
applies to Ford-completed vehicles of 10,000 pounds (4,536 kilograms)
GVWR or less. This is the weight of permanently-attached auxiliary
equipment, such as snowplow frame-mounting hardware, that can be
added to the vehicle and satisfy Ford compliance certification to
FMVSS. Exceeding this weight may require the auxiliary equipment
installer additional safety certification responsibility. The Front
Accessory Reserve Capacity (FARC) is added for customer
convenience.
•Rear ballast weight behind the rear axle may be required to prevent
exceeding the FGAWR, and provide front-to-rear weight balance for
proper braking and steering.
•Front wheel toe may require re-adjustment to prevent premature
uneven tire wear. Specifications are found in the FordWorkshop
Manual.
•Headlight aim may require re-adjustment.
•The tire air pressures recommended for general driving are found on
the vehicle’s Safety Certification Label. The maximum cold inflation
pressure for the tire and associated load rating is imprinted on the tire
sidewall. Tire air pressure may require re-adjustment within these
pressure limits to accommodate the additional weight of the snowplow
installation.
•Federal and some local regulations require additional exterior lamps
for snowplow-equipped vehicles. Consult your authorized dealer for
additional information.
Operating the Vehicle with the Snowplow Attached
Note:Do not use your vehicle for snow removal until it has been driven
at least 500 miles (800 kilometers).
Ford recommends vehicle speed does not exceed 45 mph (72 km/h)
when snowplowing.
The attached snowplow blade restricts airflow to the radiator, and may
cause the engine to run at a higher temperature: Attention to engine
temperature is especially important when outside temperatures are
above freezing. Angle the blade to maximize airflow to the radiator and
monitor engine temperature to determine whether a left or right angle
provides the best performance.
Follow the severe duty schedule in yourscheduled maintenance
informationfor engine oil and transmission fluid change intervals.

2. Remove the cap from the valve on one tire, then firmly press the tire
gauge onto the valve and measure the pressure.
3. Add enough air to reach the recommended air pressure.
Note:If you overfill the tire, release air by pushing on the metal stem in
the center of the valve. Then recheck the pressure with your tire gauge.
4. Replace the valve cap.
5. Repeat this procedure for each tire, including the spare.
Note:Some spare tires operate at a higher inflation pressure than the
other tires. For T-type or mini-spare tires, see theDissimilar spare tire
and wheel assembly informationsection. Store and maintain at 60 psi
(4.15 bar). For full-size and dissimilar spare tires, see theDissimilar
spare tire and wheel assembly informationsection. Store and maintain
at the higher of the front and rear inflation pressure as shown on the
Tire Label.
6. Visually inspect the tires to make sure there are no nails or other
objects embedded that could poke a hole in the tire and cause an air
leak.
7. Check the sidewalls to make sure there are no gouges, cuts or bulges.
Tire Inflation Information
WARNING:An inflated tire and rim can be very dangerous if
improperly used, serviced or maintained. To reduce the risk of
serious injury, never attempt to re-inflate a tire which has been run flat
or seriously under-inflated without first removing the tire from the
wheel assembly for inspection. Do not attempt to add air to tires or
replace tires or wheels without first taking precautions to protect
persons and property.
All tires with Steel Carcass Plies (if equipped):
This type of tire utilizes steel cords in the sidewalls. As such, they
cannot be treated like normal light truck tires. Tire service, including
adjusting tire pressure, must be performed by personnel trained,
supervised and equipped according to Federal Occupational Safety and
Health Administration regulations. For example, during any procedure
involving tire inflation, the technician or individual must utilize a remote
inflation device, and make sure that all persons are clear of the
trajectory area.

Important:Remember to replace the wheel valve stems when the road
tires are replaced on your vehicle.
The two front tires or two rear tires should generally be replaced as a pair.
The tire pressure sensors mounted in the wheels are not designed to be
used in aftermarket wheels.
The use of wheels or tires not recommended by Ford Motor Company may
affect the operation of your tire pressure monitoring system(if equipped).
If the tire pressure monitoring system indicator is flashing, the system is
malfunctioning. Your replacement tire might be incompatible with your
tire pressure monitoring system, or some component of the system may
be damaged(if equipped).
Safety Practices
WARNING:If your vehicle is stuck in snow, mud, or sand, do not
rapidly spin the tires. Spinning the tires can tear the tire and cause
an explosion. A tire can explode in as little as three to five seconds.
WARNING:Do not spin the wheels at over 35 mph (56 km/h).
The tires may fail and injure a passenger or bystander.
Driving habits have a great deal to do with your tire mileage and safety.
•Observe posted speed limits.
•Avoid fast starts, stops and turns.
•Avoid potholes and objects on the road.
•Do not run over curbs or hit the tire against a curb when parking.
Highway Hazards
No matter how carefully you drive, there is always the possibility that
you may eventually have a flat tire on the highway. Drive slowly to the
closest safe area out of traffic. This may further damage the flat tire, but
your safety is more important.
If you feel a sudden vibration or ride disturbance while driving, or you
suspect your tire or vehicle has been damaged, immediately reduce your
speed. Drive with caution until you can safely pull off the road. Stop and
inspect the tires for damage. If a tire is under-inflated or damaged,
deflate it, remove the wheel and replace it with your spare tire and
wheel. If you cannot detect a cause, have the vehicle towed to the
nearest repair facility or tire dealer to have the vehicle inspected.
