TOWING A TRAILER
WARNING:Do not exceed the GVWR or the GAWR specified on
the certification label.
WARNING:Towing trailers beyond the maximum recommended
gross trailer weight exceeds the limit of the vehicle and could
result in engine damage, transmission damage, structural damage, loss
of vehicle control, vehicle rollover and personal injury.
Your vehicle’s load capacity is designated by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.
Towing a trailer places an additional load on your vehicle’s engine,
transmission, axle, brakes, tires and suspension. Inspect these
components periodically during, and after, any towing operation.
TRAILER SWAY CONTROL (IF EQUIPPED)
WARNING:Turning off the trailer sway control increases the risk
of loss of vehicle control, serious injury or death. Ford does not
recommend turning off this feature except in situations where reducing
vehicle speed may be dangerous (e.g. driving uphill) or the driver has
significant trailer towing experience and can control trailer sway and
maintain safe operation.
Note:This feature does not prevent trailer sway, but reduces it once it
begins.
Note:This feature cannot stop all trailers from swaying.
Note:In some cases, if vehicle speed is too high, the system may
activate multiple times, gradually reducing vehicle speed.
This feature applies the vehicle brakes at individual wheels and, if
necessary, reduces engine power. If the trailer begins to sway, the
traction control system light flashes andTRAILER SWAY REDUCE
SPEEDappears in the information display. The first thing to do is slow
the vehicle down, then pull safely to the side of the road and check for
proper tongue load and trailer load distribution. Refer toLoad Carrying
chapter for specific loading information.
Trailer sway control can be turned off by using the information display
control; refer to theInformation Displayschapter. The system turns
back on whenever the ignition is turned on.

BREAKING-IN
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.
Do not add friction modifier compounds or special break-in oils since
these additives may prevent piston ring seating.
ECONOMICAL DRIVING
Fuel economy is affected by several things such as how you drive, the
conditions you drive under and how you maintain your vehicle.
There are some things to keep in mind that may improve your fuel
economy:
•Accelerate and slow down in a smooth, moderate fashion.
•Drive at steady speeds without stopping.
•Anticipate stops; slowing down may eliminate the need to stop.
•Combine errands and minimize stop-and-go driving.
•Close the windows for high-speed driving.
•Drive at reasonable speeds (traveling at 55 mph [88 km/h] uses 15%
less fuel than traveling at 65 mph [105 km/h]).
•Keep the tires properly inflated and use only the recommended size.
•Use the recommended engine oil.
•Perform all regularly scheduled maintenance.
There are also some things you may not want to do because they may
reduce your fuel economy:
•Sudden or hard accelerations.
•Rev the engine before turning it off.
•Idle for periods longer than one minute.
•Warm up your vehicle on cold mornings.
•Use the air conditioner or front defroster.
•Use the speed control in hilly terrain.
•Rest your foot on the brake pedal while driving.
Driving Hints277
2013 Flex(471)
Owners Guide gf, 1st Printing
USA(fus)

•Start the engine every 15 days. Run at fast idle until it reaches normal
operating temperature.
•With your foot on the brake, shift through all the gears while the
engine is running.
Fuel system
•Fill the fuel tank with high-quality fuel until the first automatic shutoff
of the fuel pump nozzle.
Note:During extended periods of vehicle storage (30 days or more), fuel
may deteriorate due to oxidation. Add a quality gas stabilizer product to
the vehicle fuel system whenever actual or expected storage periods
exceed 30 days. Follow the instructions on the additive label. The vehicle
should then be operated at idle speed to circulate the additive
throughout the fuel system.
Cooling system
•Protect against freezing temperatures.
•When removing vehicle from storage, check coolant fluid level.
Confirm there are no cooling system leaks, and fluid is at the
recommended level.
Battery
•Check and recharge as necessary. Keep connections clean.
•If storing your vehicle for more than 30 days without recharging the
battery, it may be advisable to disconnect the battery cables to ensure
battery charge is maintained for quick starting.
Note:If battery cables are disconnected, it will be necessary to reset
memory features.
Brakes
•Make sure brakes and parking brake are fully released.
Tires
•Maintain recommended air pressure.
Miscellaneous
•Make sure all linkages, cables, levers and pins under vehicle are
covered with grease to prevent rust.
•Move vehicles at least 25 feet (8 m) every 15 days to lubricate
working parts and prevent corrosion.

GENERAL INFORMATION
Notice To Crossover Vehicle Owners
Crossover vehicles handle differently
than passenger cars in the various
driving conditions that are
encountered on streets, highways and
off-road. Crossover vehicles 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:Crossover 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 manual for specific information about equipment
features, instructions for safe driving and additional precautions to
reduce the risk of an accident or serious injury.
All-Wheel Drive (AWD) System (If Equipped)
WARNING:Do not become overconfident in the ability of AWD
vehicles. Although a 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.
Wheels and Tires339
2013 Flex(471)
Owners Guide gf, 1st Printing
USA(fus)

Note:Your AWD vehicle is not intended for off-road use. This feature
gives your vehicle some limited off-road capabilities in which driving
surfaces are relatively level, obstruction-free and otherwise similar to
normal on-road driving conditions. Operating your vehicle under other
than those conditions could subject the vehicle to excessive stress which
might result in damage which is not covered under your warranty.
With the AWD option, power will be delivered to the front wheels and
distributed to the rear wheels as needed. This increases traction which
may enable you to safely drive over terrain and road conditions that a
conventional two-wheel drive vehicle cannot. The system is active all the
time and requires no input from the operator.
For AWD vehicles, a spare tire of a different size other than the tire
provided should never be used. A dissimilar spare tire size (other than
the spare tire provided) or major dissimilar tire sized between the front
and rear axles could cause the system to stop functioning and default to
front-wheel drive.
How Your Vehicle Differs from Other Vehicles
Crossover vehicles can differ from
some other vehicles in a few
noticeable ways. Your vehicle may
be:
•Higher – to allow higher load
carrying capacity.
•Shorter – to give it the capability
to approach inclines. 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.
•Narrower – to provide greater
maneuverability in tight spaces.
As a result of the above dimensional differences, crossover vehicles often
will have a higher center of gravity and a greater difference in center of
gravity between the loaded and unloaded condition.
These differences that make your vehicle so versatile also make it handle
differently than an ordinary passenger car.

TIRE CARE
Information About Uniform Tire Quality Grading
Tire Quality Grades apply to new
pneumatic passenger car tires. The
Quality grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example:
•Treadwear 200 Traction AA Temperature A
These Tire Quality Grades are determined by standards that the United
States Department of Transportation has set.
Tire Quality Grades apply to new pneumatic passenger car tires. They do
not apply to deep tread, winter-type snow tires, space-saver or temporary
use spare tires, light truck or “LT” type tires, tires with nominal rim
diameters of 10 to 12 inches or limited production tires as defined in
Title 49 Code of Federal Regulations Part 575.104(c)(2).
U.S. Department of Transportation-Tire quality grades:The U.S.
Department of Transportation requires Ford Motor Company to give you
the following information about tire grades exactly as the government
has written it.
Treadwear
The treadwear grade is a comparative rating based on the wear rate of
the tire when tested under controlled conditions on a specified
government test course. For example, a tire graded 150 would wear one
and one-half (1
12) times as well on the government course as a tire
graded 100. The relative performance of tires depends upon the actual
conditions of their use, however, and may depart significantly from the
norm due to variations in driving habits, service practices, and
differences in road characteristics and climate.

Traction AA A B C
WARNING:The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not include
acceleration, cornering, hydroplaning or peak traction characteristics.
The traction grades, from highest to lowest are AA, A, B, and C. The
grades represent the tire’s ability to stop on wet pavement as measured
under controlled conditions on specified government test surfaces of
asphalt and concrete. A tire marked C may have poor traction
performance.
Temperature A B C
WARNING:The temperature grade for this tire is established for
a tire that is properly inflated and not overloaded. Excessive
speed, underinflation, or excessive loading, either separately or in
combination, can cause heat buildup and possible tire failure.
The temperature grades are A (the highest), B and C, representing the
tire’s resistance to the generation of heat and its ability to dissipate heat
when tested under controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to a level of performance
which all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 139. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by
law.
Glossary of Tire Terminology
•Tire label:A label showing the OE (Original Equipment) tire sizes,
recommended inflation pressure and the maximum weight the vehicle
can carry.
•Tire Identification Number (TIN):A number on the sidewall of
each tire providing information about the tire brand and manufacturing

•PSI:Pounds per square inch, a standard unit of air pressure.
•Cold inflation pressure:The tire pressure when the vehicle has
been stationary and out of direct sunlight for an hour or more and
prior to the vehicle being driven for 1 mile (1.6 km).
•Recommended inflation pressure:The cold inflation pressure found
on the Safety Compliance Certification Label (affixed to either the
door hinge pillar, door-latch post, or the door edge that meets the
door-latch post, next to the driver ’s seating position), or Tire Label
located on the B-Pillar or the edge of the driver’s door.
•B-pillar:The structural member at the side of the vehicle behind the
front door.
•Bead area of the tire:Area of the tire next to the rim.
•Sidewall of the tire:Area between the bead area and the tread.
•Tread area of the tire:Area of the perimeter of the tire that
contacts the road when mounted on the vehicle.
•Rim:The metal support (wheel) for a tire or a tire and tube assembly
upon which the tire beads are seated.
Information Contained on the Tire Sidewall
Both U.S. and Canada Federal regulations require tire manufacturers to
place standardized information on the sidewall of all tires. This
information identifies and describes the fundamental characteristics of
the tire and also provides a U.S. DOT Tire Identification Number for
safety standard certification and in case of a recall.

Information on “P” Type Tires
P215/65R15 95H is an example of a
tire size, load index and speed
rating. The definitions of these
items are listed below. (Note that
the tire size, load index and speed
rating for your vehicle may be
different from this example.)
A.P:Indicates a tire, designated by the Tire and Rim Association
(T&RA), that may be used for service on cars, SUVs, minivans and light
trucks.
Note:If your tire size does not begin with a letter this may mean it is
designated by either ETRTO (European Tire and Rim Technical
Organization) or JATMA (Japan Tire Manufacturing Association).
B.215:Indicates the nominal width of the tire in millimeters from
sidewall edge to sidewall edge. In general, the larger the number, the
wider the tire.
C.65:Indicates the aspect ratio which gives the tire’s ratio of height to
width.
D.R:Indicates a “radial” type tire.
E.15:Indicates the wheel or rim diameter in inches. If you change your
wheel size, you will have to purchase new tires to match the new wheel
diameter.
F.95:Indicates the tire’s load index. It is an index that relates to how
much weight a tire can carry. You may find this information in your
owner’s manual. If not, contact a local tire dealer.
Note:You may not find this information on all tires because it is not
required by federal law.

G.H:Indicates the tire’s speed rating. The speed rating denotes the
speed at which a tire is designed to be driven for extended periods of
time under a standard condition of load and inflation pressure. The tires
on your vehicle may operate at different conditions for load and inflation
pressure. These speed ratings may need to be adjusted for the difference
in conditions. The ratings range from 81 mph (130 km/h) to 186 mph
(299 km/h). These ratings are listed in the following chart.
Note:You may not find this information on all tires because it is not
required by federal law.
Letter rating Speed rating - mph (km/h)
M 81 mph (130 km/h)
N 87 mph (140 km/h)
Q 99 mph (159 km/h)
R 106 mph (171 km/h)
S 112 mph (180 km/h)
T 118 mph (190 km/h)
U 124 mph (200 km/h)
H 130 mph (210 km/h)
V 149 mph (240 km/h)
W 168 mph (270 km/h)
Y 186 mph (299 km/h)
Note:For tires with a maximum speed capability over 149 mph
(240 km/h), tire manufacturers sometimes use the letters ZR. For those
with a maximum speed capability over 186 mph (299 km/h), tire
manufacturers always use the letters ZR.
H.U.S. DOT Tire Identification Number (TIN):This begins with the
letters “DOT” and indicates that the tire meets all federal standards. The
next two numbers or letters are the plant code designating where it was
manufactured, the next two are the tire size code and the last four
numbers represent the week and year the tire was built. For example,
the numbers 317 mean the 31st week of 1997. After 2000 the numbers
go to four digits. For example, 2501 means the 25th week of 2001. The
numbers in between are identification codes used for traceability. This
information is used to contact customers if a tire defect requires a recall.
I.M+S or M/S:Mud and Snow, or
AT:All Terrain, or
AS:All Season.
