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
1 2) 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
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.
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.
Temperature A B C
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.
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.
TIRES
Tires are designed to give many thousands of miles of service, but they
must be maintained in order to get the maximum benefit from them.

8.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.
9.M+S or M/S:Mud and Snow, or
AT:All Terrain, or
AS:All Season.
10.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.
11.Maximum Load:Indicates the maximum load in kilograms and
pounds that can be carried by the tire. Refer to the Safety Compliance
Certification Label, which is located on the B-Pillar or the edge of the
driver’s door, for the correct tire pressure for your vehicle.
12.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
1 2) 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.
13.Maximum Permissible Inflation Pressure:Indicates the tire
manufacturers’ maximum permissible pressure and/or the pressure at
which the maximum load can be carried by the tire. This pressure is
normally higher than the manufacturer’s recommended cold inflation
pressure which can be found on the Safety Compliance Certification

SNOW TIRES AND CHAINS
WARNING:Snow tires must be the same size, load index, speed
rating as those originally provided by Ford. The use of
non-recommended tires and wheels could cause steering, suspension,
axle or transfer case/power transfer unit failure. Using any tire or
wheel not recommended by Ford may increase the risk of loss of
vehicle control or vehicle rollover, which could result in personal injury
or death.
The tires on your vehicle have all-weather treads to provide traction in
rain and snow. However, in some climates, using snow tires or traction
devices may be necessary. Ford offers tire cables as a Ford approved
accessory and recommends use of these or SAE class “S” tire cables. See
your authorized dealer for more information on tire cables for your
vehicle.
Follow these guidelines when using snow tires and traction devices:
•Use only SAE Class S chains.
•Cables should only be used on the rear wheels.
•Do not use tire chains, cables or optional traction devices on 17, 18 or
20 inch wheels and tires.
•Install cables securely, verifying that the cables do not touch any
wiring, brake lines or fuel lines.
•Drive cautiously. If you hear the cables rub or bang against the
vehicle, stop and retighten them. If this does not work, remove the
cables to prevent vehicle damage.
•Avoid overloading your vehicle.
•Remove the cables when they are no longer needed.
•Do not use cables on dry roads.
•Do not exceed 30 mph (48 km/h) with tire cables on your vehicle.
Consult your authorized dealer for information on other Ford Motor
Company approved methods of traction control.
VEHICLE LOADING – WITH AND WITHOUT A TRAILER
This section will guide you in the proper loading of your vehicle and/or
trailer, to keep your loaded vehicle weight within its design rating
capability, with or without a trailer. Properly loading your vehicle will
provide maximum return of vehicle design performance. Before loading

WARNING:If a failure has been detected within the
AdvanceTracwith RSCsystem, thesliding caricon
will
illuminate steadily. Verify that the AdvanceTracwith RSCsystem is
not manually disabled (push the AdvanceTracwith RSC“Off “
button located on the center of the instrument panel). If thesliding
caricon
still illuminates steadily, have the system serviced by an
authorized dealer immediately. Operating your vehicle with
AdvanceTracwith RSCdisabled could lead to an increased risk of
loss of vehicle control, vehicle rollover, personal injury and death.
The AdvanceTracwith RSCsystem provides the following stability
enhancement features for certain driving situations:
•Traction Control (TCS), which functions to help avoid drive-wheel
spin and loss of traction.
•Electronic Stability Control (ESC), which functions to help avoid skids
or lateral slides
•Roll Stability Control™ (RSC), which functions to help avoid a
vehicle roll-over.
The AdvanceTracwith RSCsystem automatically enables each time
the engine is started. All features of the AdvanceTracwith RSCsystem
(TCS, ESC, and RSC) are active and monitor the vehicle from start-up.
However, the system will only intervene if the driving situation requires
it.
The AdvanceTracwith RSC
system includes an AdvanceTrac
with RSCOffbuttononthe
center of the instrument panel, and
a “sliding car” icon
in the
instrument cluster. The “sliding car”
icon
in the instrument cluster will illuminate temporarily during
start-up as part of a normal system self-check, or during driving if a
driving situation causes the AdvanceTracwith RSCsystem to operate.
If the “sliding car” icon
illuminates steadily, verify that the
AdvanceTracwith RSCsystem is not manually disabled by pressing
the AdvanceTracwith RSCOffbutton located on the center stack of
the instrument panel. If the “sliding car” icon
remains steadily
illuminated, or if the message center (if equipped) displays SERVICE
RSC NOW, have the system serviced by an authorized dealer
immediately.

When AdvanceTracwith RSCperforms a normal system self-check,
some drivers may notice a slight movement of the brake, and/or a
rumble, grunting, or grinding noise after startup and when driving off.
When an event occurs that activates AdvanceTracwith RSCyou may
experience the following:
•A slight deceleration of the vehicle
•The “sliding car”
indicator light will flash.
•A vibration in the pedal when your foot is on the brake pedal
•If the driving condition is severe and your foot is not on the brake, the
brake pedal may move as the systems applies higher brake forces. You
may also hear a whoosh of air from under the instrument panel during
this severe condition.
•The brake pedal may feel stiffer than usual.
Traction Control (TCS)
Traction Control is a driver aid feature that helps your vehicle maintain
traction of the wheels, typically when driving on slippery and/or hilly
road surfaces, by detecting and controlling wheel spin.
Excessive wheel spin is controlled in two ways, which may work
separately or in tandem: Engine Traction Control and Brake Traction
Control. Engine Traction Control works to limit drive-wheel spin by
momentarily reducing engine power. Brake Traction Control works to
limit wheel spin by momentarily applying the brakes to the wheel that is
slipping. Traction Control is most active at low speeds.
During Traction Control events the “sliding car” icon
in the
instrument cluster will flash.
If the Traction Control system is activated excessively in a short period
of time, the braking portion of the system may become temporarily
disabled to allow the brakes to cool down. In this situation, Traction
Control will use only engine power reduction or transfer to help control
the wheels from over-spinning. When the brakes have cooled down, the
system will regain all features. Anti-lock braking, RSC, and ESC are not
affected by this condition and will continue to function during the
cool-down period.
The Engine Traction Control and Brake Traction Control system may be
deactivated in certain situations. See theSwitching Off AdvanceTrac
with RSCsection following.

Switching Off AdvanceTracwith RSC
If the vehicle is stuck in snow, mud or sand, and seems to lose engine
power, switching off certain features of the AdvanceTracwith RSC
system may be beneficial because the wheels are allowed to spin. This
will restore full engine power and will enhance momentum through the
obstacle. To switch off the AdvanceTracwith RSCsystem press the
AdvanceTracwith RSCOffbutton. Full features of the AdvanceTrac
with RSCsystem can be restored by pressing the AdvanceTracwith
RSCOffbutton again or by turning off and restarting the engine.
If you switch off the AdvanceTracwith RSCsystem, the sliding car
icon
will illuminate steadily. Pressing the AdvanceTracwith RSC
Offbutton again will turn off thesliding caricon
.
In R (Reverse), ABS and the Engine and Brake Traction Control features
will continue to function; however, ESC and RSCare disabled.
