PRINCIPLE OF OPERATION
Electronic Stability Program
WARNINGS
The system does not relieve you of
your responsibility to drive with due
care and attention. Failure to drive
with due care and attention could lead to
loss of vehicle control. Vehicle modifications involving
braking system, aftermarket roof
racks, suspension, steering system,
tire construction and wheel and tire size
may change the handling characteristics
of the vehicle and may adversely affect
the performance of the AdvanceTrac
system. 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 AdvanceTrac sensors. Reducing the
effectiveness of the AdvanceTrac system
could lead to an increased risk of loss of
vehicle control, vehicle rollover, personal
injury and death. 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
AdvanceTrac system 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 AdvanceTrac
system activates, SLOW DOWN. Without Advance Trac

The system supports stability when your
vehicle starts to slide away from your
intended path. This is performed by braking
individual wheels and reducing engine
torque as needed.
The system also provides an enhanced
traction control function by reducing
engine torque if the wheels spin when you
accelerate. This improves your ability to
pull away on slippery roads or loose
surfaces, and improves comfort by limiting
wheel spin in hairpin bends.
Stability Control Warning Lamp
While driving, it flashes when the system
is operating. See Warning Lamps and
Indicators (page 79).

•
Combine errands and minimize
stop-and-go driving.
•When running errands, go to the
furthest destination first and then
work your way back home.
• Close the windows for high-speed
driving.
• Drive at reasonable speeds. (Traveling
at 65 mph/105 kph uses about 15%
less fuel than traveling at 75 mph/121
kph).
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.
There are also some things you may want
to avoid doing because they reduce your
fuel economy:
• Avoid sudden or hard accelerations.
• Avoid revving the engine before turning
off the car.
• Avoid long idle periods.
• Do not warm up your vehicle on cold
mornings.
• Reduce the use of air conditioning and
heat.
• Avoid using speed control in hilly
terrain.
• Do not rest your foot on the brake
pedal while driving.
• Avoid carrying unnecessary weight
(approximately 1 mpg [0.4
kilometers/liter] is lost for every 400
lbs [180 kilograms] of weight carried).
• Avoid adding particular accessories to
your vehicle (e.g. bug deflectors,
rollbars/light bars, running boards, ski
racks).
• Avoid driving with the wheels out of
alignment. FLOOR MATS
WARNINGS
Always use floor mats that are
designed to fit the foot well of your
vehicle. Only use floor mats that
leave the pedal area unobstructed. Only
use floor mats that are firmly secured to
retention posts so that they cannot slip out
of position and interfere with the pedals
or impair safe operation of your vehicle in
other ways. Pedals that cannot move freely can
cause loss of vehicle control and
increase the risk of serious personal
injury. Always make sure that the floor
mats are properly attached to the
retention posts in the carpet that are
supplied with your vehicle. Floor mats must
be properly secured to both retention posts
to ensure mats do not shift out of position. Never place floor mats or any other
covering in the vehicle foot well that
cannot be properly secured to
prevent them from moving and interfering
with the pedals or the ability to control the
vehicle.

GENERAL INFORMATION
A decal with tire pressure data is located
in the driver
’s door opening.
Check and set the tire pressure at the
ambient temperature in which you are
intending to drive your vehicle and when
the tires are cold.
Note: Check your tire pressures regularly to
optimize fuel economy.
Note: Use only approved wheel and tire
sizes. Using other sizes could damage your
vehicle and will make the National Type
Approval invalid.
Note: If you change the diameter of the tires
from that fitted at the factory, the
speedometer may not display the correct
speed. Take your vehicle to an authorized
dealer to have the engine management
system reprogrammed.
Note: If you intend to change the size of the
wheels from that fitted at the factory, check
the suitability with an authorized dealer.
TIRE CARE
Important information for 205/40R17
low-profile tires and wheels If your
vehicle is equipped with 205/40R17 tires,
they are low-profile tires. These tires and
wheels are designed to give your vehicle a
sport appearance. With low-profile tires,
you may notice an increase in road noise
and faster tire wear, depending on road
conditions and driving styles. Due to their
design, low-profile tires and wheels are
more prone to road damage from potholes,
rough or unpaved roads, car wash rails and
curb contact than standard tires and
wheels. Note:
Your vehicle ’s warranty does not
cover these types of damage. Tires should
always be kept at the correct inflation
pressures and extra caution should be taken
when operating on rough roads to avoid
impacts that could cause wheel and tire
damage.
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 ©)(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 ½) 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, under-inflation, 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.

Location of the Tire Label
You will find a Tire Label
containing tire inflation pressure
by tire size and other important
information located on the B-Pillar
or the edge of the driver ’s door.
Inflating Your Tires
Safe operation of your vehicle
requires that your tires are
properly inflated. Remember that
a tire can lose up to half of its air
pressure without appearing flat.
Every day before you drive, check
your tires. If one looks lower than
the others, use a tire gauge to
check pressure of all tires and
adjust if required.

of the driver
’s door. The cold
inflation pressure should never be
set lower than the recommended
pressure on the Safety
Compliance Certification Label or
Tire Label.
When weather temperature
changes occur, tire inflation
pressures also change. A 10°F
(6°C) temperature drop can
cause a corresponding drop of 1
psi (7 kPa) in inflation pressure.
Check your tire pressures
frequently and adjust them to the
proper pressure which can be
found on the Safety Compliance
Certification Label or Tire Label.
To check the pressure in your
tire(s):
1. Make sure the tires are cool,
meaning they are not hot from
driving even a mile.
Note: If you are checking tire pressure when
the tire is hot, (i.e. driven more than 1 mile
[1.6 km]), never bleed or reduce air pressure.
The tires are hot from driving and it is normal
for pressures to increase above
recommended cold pressures. A hot tire at
or below recommended cold inflation
pressure could be significantly
under-inflated.
Note: If you have to drive a distance to get
air for your tire(s), check and record the tire
pressure first and add the appropriate air
pressure when you get to the pump. It is
normal for tires to heat up and the air
pressure inside to go up as you drive. 2. Remove the cap from the valve
on one tire, then firmly press the
tire gauge onto the valve and
measure the pressure.
3. Add enough air to reach the
recommended air pressure.
Note:
If you overfill the tire, release air by
pressing on the metal stem in the center of
the valve. Then recheck the pressure with
your tire gauge.
4. Replace the valve cap.
5. Repeat this procedure for each
tire, including the spare.
Note: Some spare tires operate at a higher
inflation pressure than the other tires. For T
type mini-spare tires (refer to the Dissimilar
spare wheel and tire assembly information
for a description): Store and maintain at 60
psi (4.15 bar). For full-size and dissimilar
spare tires (refer to the Dissimilar spare
wheel and tire assembly information for a
description): Store and maintain at the
higher of the front and rear inflation pressure
as shown on the Tire Label.
6. Visually inspect the tires to
make sure there are no nails or
other objects embedded that
could poke a hole in the tire and
cause an air leak.
7. Check the sidewalls to make
sure there are no gouges, cuts or
bulges.
219
Fiesta (CCT) Wheels and Tires

or suspected have the tire
inspected by a tire professional.
Tires can be damaged during
off-road use, so inspection after
off-road use is also
recommended.
Age
WARNING
Tires degrade over time depending
on many factors such as weather,
storage conditions, and conditions
of use (load, speed, inflation pressure, etc.)
the tires experience throughout their lives.
In general, tires should be replaced after
six years regardless of tread wear.
However, heat caused by hot climates or
frequent high loading conditions can
accelerate the aging process and may
require tires to be replaced more
frequently.
You should replace your spare tire when
you replace the road tires or after six years
due to aging even if it has not been used. U.S. DOT Tire Identification Number
(TIN)
Both U.S. and Canada Federal
regulations require tire
manufacturers to place
standardized information on the
sidewall of all tires. This
information identifies and
describes the fundamental
characteristics of the tire and also
provides a U.S. DOT Tire
Identification Number for safety
standard certification and in case
of a recall. 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.
Tire Replacement Requirements
Your vehicle is equipped with tires
designed to provide a safe ride
and handling capability.
WARNINGS
Only use replacement tires and
wheels that are the same size, load
index, speed rating and type (such
as P-metric versus LT-metric or all-season
versus all-terrain) as those originally
provided by Ford. The recommended tire
and wheel size may be found on either the
Safety Compliance Certification Label
(affixed to either the door hinge pillar,
door-latch post, or the door edge that
meets the door-latch post, next to the
driver's seating position), or the Tire Label
which is located on the B-Pillar or edge of
the driver ’s door. If this information is not
found on these labels then you should
contact your authorized dealer as soon as
