How does the air bag
supplemental restraint system
work?
The Air Bag Supplemental
Restraint System is designed to
activate when the vehicle sustains
sufficient longitudinal (lengthwise)
deceleration that is equal to or
greater than hitting an immovable
barrier head on at a range of about
12±24 km/h (8±14 mph).
The fact that the air bags did not
inflate in a collision does not mean
that something is wrong with the
system. Rather, it means the forces
were not of the type sufficient to
cause activation.
If the vehicle experiences
sufficient longitudal deceleration,
the system is activated and the air
bags inflate rapidly. After the air
bag inflates, it will quickly deflate.
This occurs so quickly that some
people may not even realize that
the air bag inflated.
After the air bag deployment, you
may notice a smoke-like, powdery
residue or smell the burnt
propellant (which is used to
lubricate the air bag) or sodium
compounds, such as sodium
carbonates (e.g., baking soda) that
result from the combustion process

INFORMATION ABOUT TIRE
QUALITY GRADES
New vehicles are fitted with tires
that have their Tire Quality Grade
(described below) molded into the
tire's sidewall. These Tire Quality
Grades are determined by
standards that the United States
Department of Transportation has
set.
Tire Quality Grades apply to new
pneumatic tires for use on
passenger cars. They do not apply
to deep tread, winter-type snow
tires, space-saver or temporary use
spare 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 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 grade 150
would wear one and one-half (1
1/2) times as well on the
government course as a tire grade
100. The relative performance of
tires depends upon the actual

Replacing the tires
Replace the tires when the wear
band is visible through the tire
treads.
When replacing full size
tires, never mix radial,
bias-belted, or bias-type tires.
Use only the tire sizes that are
listed on the tire pressure decal.
Make sure that all tires are the
same size, speed rating, and
load-carrying capacity. Use only
the tire combinations
recommended on the decal. If
you do not follow these
precautions, your vehicle may
not drive properly and safely.
When purchasing replacement tires
for your vehicle, consult your
dealer or qualified service
technician to ensure that the
correct tire types are used.
