2013 FORD EXPLORER 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
In certain situations (e.g. 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 off the traction control system using the information
display control. Refer to 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.

PRINCIPLES OF OPERATION
WARNING:Vehicle modifications involving braking system,
aftermarket roof racks, suspension, steering system, tire
construction and/or wheel/tire size may change the handling
characteristics of the vehicle and may adversely affect the performance
of the AdvanceTracsystem. In addition, installing any stereo
loudspeakers may interfere with and adversely affect the AdvanceTrac
system. Install any aftermarket stereo loudspeaker as far as possible
from the front center console, the tunnel, and the front seats in order
to minimize the risk of interfering with the AdvanceTracsensors.
Reducing the effectiveness of the AdvanceTracsystem could lead to
an increased risk of loss of vehicle control, vehicle rollover, personal
injury and death.
WARNING:Remember that even advanced technology cannot
defy the laws of physics. It’s always possible to lose control of a
vehicle due to inappropriate driver input for the conditions. Aggressive
driving on any road condition can cause you to lose control of your
vehicle increasing the risk of personal injury or property damage.
Activation of the AdvanceTracsystem is an indication that at least
some of the tires have exceeded their ability to grip the road; this could
reduce the operator’s ability to control the vehicle potentially resulting
in a loss of vehicle control, vehicle rollover, personal injury and death. If
your AdvanceTracsystem activates, SLOW DOWN.
The AdvanceTracwith Roll Stability Control™ (RSC) system helps you
keep control of your vehicle when on a slippery surface. The electronic
stability control (ESC) portion of the system helps avoid skids and lateral
slides, curve control assists in vehicle handling in following the road
during adverse maneuvering and roll stability control helps avoid a
vehicle rollover. The traction control system (TCS) helps avoid drive
wheel spin and loss of traction. (For details on TCS operation, see the
Traction Controlchapter.)

TERRAIN MANAGEMENT (IF EQUIPPED)
This system optimizes drivability and comfort as well as maximizing
traction while operating on different types of terrain.
Turn the control located on the center console to choose between the
following modes:
1.Grass/Gravel/Snowmode should be selected where a firm surface is
covered with loose or slippery material such as packed snow, ice, water,
grass, or a thin layer of gravel or sand. For deep gravel or sand, select
Sand mode. If the vehicle cannot gain traction in deep snow, turning off
the traction control system may help (turn traction control back on when
traction is regained). See theTraction Controlchapter.
2.Sandmode should be selected in soft dry sand or deep gravel. If
crossing wet sand that may be sufficiently deep enough for the wheels to
sink into the surface, select Mud/Ruts mode.
3.Mud/Rutsmode should be selected for muddy, rutted, soft, or uneven
terrain.
4.Normalmode is for on-road conditions and should be selected before
driving on surfaces which are similar to a hard road surface or once the
need for a special mode has passed. Select Normal mode when towing a
trailer.
Note:Cruise control is available only in Normal and Snow modes.
Note:The Sand and Mud/Ruts modes are for off-road use only.
Note:The curve control portion of the AdvanceTracsystem is
unavailable when Sand or Mud/Ruts is selected.

Deactivating the Park Assist Feature
The system can be deactivated manually by:
•pressing the active park assist button
•grabbing the steering wheel
•driving above approximately 20 mph (35 km/h) for 30 seconds during
an active park search
•driving above 6 mph (10 km/h) during automatic steering
•turning off the traction control system.
Certain vehicle conditions can also deactivate the system:
•Traction control has activated on a slippery or loose surface.
•Anti-lock brake system activation or failure.
•Any door (except the driver’s) opens.
•Something touches the steering wheel.
If a problem occurs with the system, a warning message is displayed,
followed by a chime. Occasional active park assist messages may occur in

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.

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
plant, tire size and date of manufacture. Also referred to as DOT code.
•Inflation pressure:A measure of the amount of air in a tire.
