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
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.

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
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.
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.

8. Remove the valve cap from the valve stem on the right rear tire;
decrease the air pressure until the horn sounds.
9. Remove the valve cap from the valve stem on the left rear tire;
decrease the air pressure until the horn sounds.
Training is complete after the horn sounds for the last tire trained
(driver’s side rear tire), the TPMS indicator stops flashing, and the
message center (if equipped) displays:
TRAINING COMPLETE.
10. Turn the ignition off. If two short horn beeps are heard, the reset
procedure was unsuccessful and must be repeated.
If after repeating the procedure and two short beeps are heard when the
ignition is turned to off, seek assistance from your authorized dealer.
11. Set all four tires to the recommended air pressure as indicated on
the Safety Compliance Certification Label or Tire Label located on the
B-Pillar or the edge of the driver’s door. SeeVehicle loading - with and
without a trailerin this chapter for more information.
SNOW TIRES AND CHAINS
WARNING: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 steel
wheels (of the same size and specifications) be used, as chains may chip
aluminum wheels.
Note:The suspension insulation and bumpers will help prevent vehicle
damage. Do not remove these components from your vehicle when using
snow tires and chains.
Note:Do not place chains on the following tires sizes: P265/60R18,
P275/65R18, LT275/70R17, LT275/65R18, LT315/70R17, P275/55R20, and
P275/45R22.

WARNING:Always set the parking brake fully and make sure
that the gearshift is securely latched in P (Park) (automatic
transmission) or in 1 (First) (manual transmission).
Brake override
This vehicle is equipped with a brake override feature. In the event the
accelerator pedal becomes stuck or entrapped, applying steady and firm
pressure to the brake pedal will both slow the vehicle and reduce engine
power. If you experience this condition, apply the brakes and bring your
vehicle to a safe stop. Turn the engine off, shift to P (Park) and apply
the parking brake, and then inspect the accelerator pedal for any
interferences. If none are found and the condition persists, have your
vehicle towed to the nearest dealer.
ADVANCETRACWITH ROLL STABILITY CONTROL™ (RSC)
STABILITY ENHANCEMENT SYSTEM
The AdvanceTracwith RSCsystem provides the following stability
enhancement features for certain driving situations:
•Traction control system (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.
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 AdvanceTracwith RSCsystem. In addition, installing any
stereo loudspeakers may interfere with and adversely affect the
AdvanceTracwith RSCsystem. 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 AdvanceTracwith RSCsensors. Reducing the effectiveness
of the AdvanceTracwith RSCsystem could lead to an increased risk
of loss of vehicle control, vehicle rollover, personal injury and death.
