2015 FORD FLEX traction control

PRINCIPLES OF OPERATION
The traction control system helps avoid drive wheel spin and loss of
traction.
If your vehicle begins to slide, the system applies the brakes to individual
wheels and, when needed, reduces engine power at the same time. If the
wheels spin when accelerating on slippery or loose surfaces, the system
reduces engine power in order to increase traction.
USING TRACTION CONTROL
Note:If your vehicle is equipped with MyKey™, it is possible to prevent
turning the traction control system off. See theMyKeychapter.
In certain situations (for example, stuck in snow or mud), turning the
traction control off may be beneficial as this allows the wheels to spin
with full engine power. Turn the traction control system off through the
information display. See theInformation Displayschapter.
System Indicator Lights and Messages
WARNING:If a failure has been detected within the Traction
Control System, the stability control light will illuminate steadily.
Verify that the Traction Control System was not manually disabled
using the information display control. If the stability control light still
illuminates steadily, have the system serviced by an authorized dealer
immediately. Operating your vehicle with Traction Control disabled
could lead to an increased risk of loss of vehicle control, vehicle
rollover, personal injury and death.
The stability control light temporarily illuminates on engine
start-up and flashes when a driving condition activates the
stability system.
The stability control off light temporarily illuminates on engine
start-up and stays on when the traction control system is
turned off or if a problem occurs in the stability system.
When the traction control system is turned off or on, a message appears
in the information display showing system status.

•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.
DRIVING THROUGH WATER
WARNING:Do not drive through flowing or deep water as you
may lose control of your vehicle.
Note:Driving through standing water can cause vehicle damage.
Note:Engine damage can occur if water enters the air filter.
Before driving through standing water, check the depth. Never drive
through water that is higher than the bottom of the front rocker area of
your vehicle.
When driving through standing
water, drive very slowly and do not
stop your vehicle. Your brake
performance and traction may be
limited. After driving through water
and as soon as it is safe to do so:
•Lightly press the brake pedal to
dry the brakes and to check that
they work.
•Check that the horn works.
•Check that the exterior lights work.
•Turn the steering wheel to check that the steering power assist works.
FLOOR MATS
WARNING:Always use floor mats that are designed to fit the
foot well of your vehicle. Only use floor mats that leave the pedal
area unobstructed. Only use floor mats that are firmly secured to
retention posts so that they cannot slip out of position and interfere
with the pedals or impair safe operation of your vehicle in other ways.
WARNING:Pedals that cannot move freely can cause loss of
vehicle control and increase the risk of serious personal injury.

TIRE CARE
Information About Uniform Tire Quality Grading
Tire Quality Grades apply to new
pneumatic passenger car tires. The Tire
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 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 plant, tire size and date of manufacture. Also referred
to as DOT code.

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.
J.Tire Ply Composition and Material Used:Indicates the number of
plies or the number of layers of rubber-coated fabric in the tire tread and
sidewall. Tire manufacturers also must indicate the ply materials in the
tire and the sidewall, which include steel, nylon, polyester, and others.
K.Maximum Load:Indicates the maximum load in kilograms and
pounds that can be carried by the tire. See 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), for the correct tire pressure for your vehicle.
L.Treadwear, Traction and Temperature Grades
•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.
•Traction: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: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.

The tires on your vehicle have all-weather treads to provide traction in
rain and snow. However, in some climates, you may need to use snow
tires and cables. If you need to use cables, it is recommended that steel
wheels (of the same size and specifications) be used, as cables may chip
aluminum wheels.
Follow these guidelines when using snow tires and chains:
•If possible, avoid fully loading your vehicle.
•Use only SAE Class S snow chains, snow cables or equivalent on the
front axle for P235/60R17, P235/60R18, and P235/55R19 equipped
vehicles. The use of snow chains, snow cables or other traction assist
devices that are larger than SAE Class S may cause damage to your
vehicle’s wheel house, suspension and/or body.
•Do not install tire chains, cables, or optional traction devices on the
rear tires. This could cause damage to the vehicle’s wheel house or
body.
•Do not use tire chains, cables, or optional traction devices with
255/45R20 tires.
•Install cable chains securely, verifying that the cables do not touch any
wiring, brake lines or fuel lines.
•Do not exceed 30 mph (48 km/h) with tire cables on your vehicle.
•Drive cautiously. If you hear the cables rub or bang against your
vehicle, stop and retighten the cables. If this does not work, remove
the cables to prevent damage to your vehicle.
•Remove the tire cables when they are no longer needed. Do not use
tire cables on dry roads.
TIRE PRESSURE MONITORING SYSTEM
WARNING:The tire pressure monitoring system is NOT a
substitute for manually checking tire pressure. The tire pressure
should be checked periodically (at least monthly) using a tire gauge.
SeeInflating Your Tiresin this chapter. Failure to properly maintain
your tire pressure could increase the risk of tire failure, loss of control,
vehicle rollover and personal injury.
Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle has tires of a
