PERCHLORATE MATERIAL
Certain components of this vehicle such as airbag modules, seat belt
pretensioners, and button cell batteries may contain Perchlorate Material –
Special handling may apply for service or vehicle end of life disposal. See
www.dtsc.ca.gov/hazardouswaste/perchlorate.
BREAKING-IN YOUR VEHICLE
Your vehicle does not need an extensive break-in. Try not to drive
continuously at the same speed for the first 1,000 miles (1,600 km) of
new vehicle operation. Vary your speed frequently in order to give the
moving parts a chance to break in.
Drive your new vehicle at least 1,000 miles (1,600 km) before towing a
trailer. For more detailed information about towing a trailer, refer to
Trailer towing in the Tires, Wheels and Loading chapter.
Do not add friction modifier compounds or special break-in oils since
these additives may prevent piston ring seating. See Engine oil in the
Maintenance and Specifications chapter for more information on oil
usage.

Low tire pressure warning (if
equipped): Illuminates when your
tire pressure is low. If the light
remains on at start up or while
driving, the tire pressure should be
checked. Refer to Inflating your tires in the Tires, Wheels and
Loading chapter. When the ignition is first turned to on, the light will
illuminate for three seconds to ensure the bulb is working. If the light
does not turn on, have the system inspected by your authorized dealer.
For more information on this system, refer to Understanding your tire
pressure monitoring system (TPMS) in the Tires, Wheels and
Loading chapter.
Charging system: Illuminates when
the battery is not charging properly.
If it stays on while the engine is
running, there may be a malfunction
with the charging system. Contact your authorized dealer as soon as
possible. This indicates a problem with the electrical system or a related
component.
Powertrain malfunction/Reduced
power/Electronic throttle
control (RTT): Displays when the
engine has defaulted to a
“limp-home” operation or when a transmission problem has been
detected and shifting may be restricted. If the light remains on, have the
system serviced immediately by your authorized dealer.
Traction control (RTT) (if
equipped): Displays when the
traction control system is active. If
the light remains on, have the
system serviced immediately by
your authorized dealer. Refer to Traction control in the Driving chapter
for more information

NOTICE TO UTILITY VEHICLE AND TRUCK OWNERS
Utility vehicles and trucks handle
differently than passenger cars in
the various driving conditions that
are encountered on streets,
highways and off-road. Utility
vehicles and trucks are not designed
for cornering at speeds as high as
passenger cars any more than
low-slung sports cars are designed
to perform satisfactorily under
off-road conditions.
WARNING: Utility vehicles have a significantly higher rollover
rate than other types of vehicles. To reduce the risk of serious
injury or death from a rollover or other crash you must:
• Avoid sharp turns and abrupt maneuvers;
• Drive at safe speeds for the conditions;
• Keep tires properly inflated;
• Never overload or improperly load your vehicle; and
• Make sure every passenger is properly restrained.
WARNING: In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing a seat belt.
All occupants must wear seat belts and children/infants must use
appropriate restraints to minimize the risk of injury or ejection.
Study your owner’s guide and any supplements for specific information
about equipment features, instructions for safe driving and additional
precautions to reduce the risk of an accident or serious injury.
VEHICLE CHARACTERISTICS
4WD and AWD Systems (if equipped)
A vehicle equipped with AWD or 4WD (when selected) has the ability to
use all four wheels to power itself. This increases traction which may
enable you to safely drive over terrain and road conditions that a
conventional two-wheel drive vehicle cannot. Tires, Wheels and Loading
217
2010 F-250/350/450/550 (f23)
Owners Guide, 2nd Printing
USA (fus)

Power is supplied to all four wheels through a transfer case or power
transfer unit. 4WD vehicles allow you to select different drive modes as
necessary. Information on transfer case operation and shifting procedures
can be found in the Driving chapter. Information on transfer case
maintenance can be found in the Maintenance and Specifications
chapter. You should become thoroughly familiar with this information
before you operate your vehicle.
On some 4WD models, the initial shift from two-wheel drive to 4WD
while the vehicle is moving can cause a momentary clunk and ratcheting
sound. These sounds are normal as the front drivetrain comes up to
speed and is not cause for concern.
WARNING: Do not become overconfident in the ability of 4WD
and AWD vehicles. Although a 4WD or AWD vehicle may
accelerate better than two-wheel drive vehicle in low traction
situations, it won’t stop any faster than two-wheel drive vehicles.
Always drive at a safe speed.
How your vehicle differs from other vehicles
SUV and trucks can differ from
some other vehicles in a few
noticeable ways. Your vehicle may
be:
• Higher – to allow higher load
carrying capacity and to allow it
to travel over rough terrain
without getting hung up or
damaging underbody components.
• Shorter – to give it the capability
to approach inclines and drive
over the crest of a hill without
getting hung up or damaging
underbody components. All other
things held equal, a shorter
wheelbase may make your vehicle
quicker to respond to steering inputs than a vehicle with a longer
wheelbase.Tires, Wheels and Loading
