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 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.

Page 201 of 336
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.
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.
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.
•Standard load:A class of P-metric or Metric tires designed to carry a
maximum load at 35 psi [37 psi (2.5 bar) for Metric tires]. Increasing
the inflation pressure beyond this pressure will not increase the tire’s
load carrying capability.
•Extra load:A class of P-metric or Metric tires designed to carry a
heavier maximum load at 41 psi [43 psi (2.9 bar) for Metric tires].

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
Label or Tire Label which is located on the B-Pillar or the edge of the
driver’s door. The cold inflation pressure should never be set lower than
the recommended pressure on the vehicle label.
The tire suppliers may have additional markings, notes or warnings such
as standard load, radial tubeless, etc.

SNOW TIRES AND CHAINS
Snow tires must be the same size, load index, speed rating as
those originally provided by Ford. Use of any tire or wheel not
recommended by Ford can affect the safety and performance of your
vehicle, which could result in an increased risk of loss of vehicle
control, vehicle rollover, personal injury and death. Additionally, the
use of non-recommended tires and wheels could cause steering,
suspension, axle or transfer case/power transfer unit failure.
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 chains. If you need to use chains, it is recommended that only
cable chains are used with steel wheels (of the same size and
specifications) as chains may chip aluminum wheels.
Follow these guidelines when using snow tires and cable chains:
•Install cable chains only on the front wheels.
•Use only cable chains on 17 inch wheels with P235/65R17 tires.
•Do not use tire chains, cables or optional traction devices with 18 inch
and 20 inch wheels and tires.
•Drive cautiously. If you hear the cable chains rub or bang against your
vehicle, stop and re-tighten the cable chains. If this does not work,
remove the cable chains to prevent damage to your vehicle.
•If possible, avoid fully loading your vehicle.
•Remove the tire cable chains when they are no longer needed. Do not
use tire cable chains on dry roads.
•The suspension insulation and bumpers will help prevent vehicle
damage. Do not remove these components from your vehicle when
using snow tires and cable chains.
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
your vehicle, familiarize yourself with the following terms for determining
your vehicle’s weight ratings, with or without a trailer, from the vehicle’s
Tire Label or Safety Compliance Certification Label:
Base Curb Weight– is the weight of the vehicle including a full tank of
fuel and all standard equipment. It does not include passengers, cargo, or
optional equipment.

Push the parking brake pedal
downward again to release the
parking brake. Driving with the
parking brake on will cause the
brakes to wear out quickly and
reduce fuel economy.
Note:If the vehicle is driven with
the parking brake applied, a chime
will sound.
ADVANCETRACWITH ROLL STABILITY CONTROL™ (RSC)
STABILITY ENHANCEMENT SYSTEM
The AdvanceTracwith RSC system provides stability enhancement
features such as Roll Stability Control™ (RSC), Electronic Stability
Control (ESC) and Traction Control (TCS) for certain driving situations.
The system includes an AdvanceTracwith RSC on/off button, and a
“sliding car” icon in the instrument cluster.
The Anti-lock Braking System (ABS) will work with the regular brakes in
order to prevent wheel lock during a braking event. This feature will also
help provide better steerability during braking.
During AdvanceTracwith RSC operation you may experience the following:
•A rumble, grunting, or grinding noise after startup and when driving
off
•A slight deceleration of the vehicle
•The AdvanceTracwith RSC indicator light will flash when the system
is activated.
•If your foot is on the brake pedal, you will feel a vibration in the
pedal.
Traction Control
Traction Control helps your vehicle maintain traction, when driving on
slippery and/or hilly road surfaces, by detecting and controlling wheel
spin. Excessive wheel spin is controlled by momentarily reducing engine
power and/or applying the anti-lock brakes.
If your vehicle should become stuck in deep snow or mud, try switching
the AdvanceTracwith RSC system off by pressing the AdvanceTrac
with RSC button momentarily. This will allow your wheels to spin and
your tires to “dig” for traction. If your vehicle seems to lose engine
power while driving in deep sand or very deep snow, switching off the
AdvanceTrac with RSC stability enhancement feature will restore full
engine power and torque to each wheel.

If the AdvanceTracwith RSC system is activated excessively in a short
period of time, the brake portion of the system will disable to allow the
brakes to cool down. In this situation, Traction Control will use only
engine power reduction to help control the wheels from over-spinning.
When the brakes have cooled down, the system will again function
normally. Anti-lock braking, RSC and ESC are not affected by this
condition and will function normally during the cool-down period.
During Traction Control events the “sliding car” icon in the instrument
cluster will flash momentarily.
Electronic Stability Control (ESC)
The Electronic Stability Control (ESC) with RSC system may enhance
your vehicle’s stability during adverse maneuvers.
The AdvanceTracwith RSC system helps the driver maintain steering
control. AdvanceTracwith RSC will attempt to correct the vehicle
motion by applying brake force at individual tires and, if necessary, by
reducing engine power.
During Electronic Stability Control events the “sliding car” icon in the
instrument cluster will flash momentarily.
Driving maneuvers which may activate AdvanceTracwith RSC system
include:
•Taking a turn too fast.
•Maneuvering quickly to avoid an accident, pedestrian or obstacle.
•Driving over a patch of ice.
•Changing lanes on a snow-rutted road.
•Entering a snow-free road from a snow-covered side street, or vice
versa.
•Entering a paved road from a gravel road, or vice versa.
•Driving on slick surfaces.
•Cornering while towing a heavily loaded trailer (refer toTrailer
towingin theTires, Wheels and Loadingchapter.)
Roll Stability Control™ (RSC)
The RSC system works in conjunction with the AdvanceTracsystem to
help maintain roll stability of the vehicle during aggressive maneuvers by
applying brake force to one or more wheels.
During Roll Stability Control™ (RSC) events the “sliding car” icon in the
instrument cluster will flash momentarily.

Driving conditions that may activate AdvanceTracwith RSC include:
•Emergency lane-change
•Taking a turn too fast
•Quick maneuvering to avoid an accident, pedestrian or obstacle
AdvanceTracwith RSC button and icon functionality
The AdvanceTracwith RSC system automatically turns on each time
the engine is started, even if it was turned off when the engine was last
shut down. The “sliding car” icon which is located with the warning
lights in the instrument cluster will illuminate during bulb check at initial
start-up and then go off. This tells you that the system is normal and
active. All functions of the AdvanceTracwith RSC system (RSC, ESC,
Engine Traction Control, and Brake Traction Control) will be tested at
start up. When the system is left active, the “sliding car” icon will flash
only when any of the components of the system are affecting the
vehicle’s performance, otherwise the light will remain off. Consequently,
the “sliding car” icon will not be illuminated during most of your normal
driving.
The AdvanceTracwith RSC button,
located on the center stack of the
instrument panel, allows the driver
to control certain features of the
AdvanceTracwith RSC system
below 45 mph (70 km/h). If the
vehicle is below 45 mph (70 km/h), pressing the AdvanceTracwith RSC
button will disable RSC, ESC and Engine Traction Control and steadily
illuminate the “sliding car” icon. The AdvanceTracwith RSC system will
remain enabled when the vehicle speed is above 45 mph (70 km/h) even
if the button has been pressed.
In R (Reverse), ABS and the Traction Control feature will continue to
function, however ESC and RSC are disabled.
All these conditions are normal during AdvanceTracwith RSC
operation.
Do not alter or modify your vehicle’s suspension or steering; the
resulting changes to the vehicle’s handling can adversely affect
the AdvanceTracwith RSC system.

If the parking brake is fully released, but the brake warning lamp
remains illuminated, the brakes may not be working properly.
See your authorized dealer.
Do not spin the wheels at over 35 mph (56 km/h). The tires may
fail and injure a passenger or bystander.
Emergency maneuvers
•In an unavoidable emergency situation where a sudden sharp turn
must be made, remember to avoid “over-driving” your vehicle (i.e.,
turn the steering wheel only as rapidly and as far as required to avoid
the emergency). Excessive steering will result in less vehicle control,
not more. Additionally, smooth variations of the accelerator and/or
brake pedal pressure should be utilized if changes in vehicle speed are
called for. Avoid abrupt steering, acceleration or braking which could
result in an increased risk of loss of vehicle control, vehicle rollover
and/or personal injury. Use all available road surface to return the
vehicle to a safe direction of travel.
•In the event of an emergency stop, avoid skidding the tires and do not
attempt any sharp steering wheel movements.
•If the vehicle goes from one type of surface to another (i.e., from
concrete to gravel) there will be a change in the way the vehicle
responds to a maneuver (steering, acceleration or braking). Again,
avoid these abrupt inputs.
AWD Systems (if equipped)
With AWD, the vehicle uses all four wheels to power the vehicle. This
increases traction, enabling you to drive over terrain and road conditions
that a conventional two-wheel drive vehicle cannot.
Sand
When driving over sand, try to keep all four wheels on the most solid
area of the trail. Avoid reducing the tire pressures but shift to a lower
gear and drive steadily through the terrain. Apply the accelerator slowly
and avoid spinning the wheels.
