Maintenance and care
185 Relearning the idle function
Because your vehicle’s engine is
electronically controlled, some
control conditions are maintained
by power from the battery. When
the battery is disconnected or a
new battery is installed, the
computer must “relearn” its idle
conditions before your vehicle can
drive properly. To begin this
process:
1. Put the automatic transaxle
gearshift in P (Park). Put the
manual transaxle gearshift in
neutral.
2. Turn off all accessories and start
the vehicle.
3. Let the engine idle for at least
one minute.
4. The “relearning” process will
automatically complete as you
drive the vehicle.
• If you do not allow the engine to
“relearn” its idle, the idle quality of
your vehicle may be adversely
affected until the idle is eventually
“relearned”.
• If the battery has been
disconnected or if a new battery
has been installed, the clock and
preset radio stations must be reset
once the battery is reconnected.

Maintenance and care
186Checking wiper blades
Check the wiper blades on your
vehicle for roughness by running
the tips of your fingers over the
edge of the blade.
Traces of grease, silicone and fuel
prevent wiper blades from
functioning properly. We
recommend Ford cleaning
solutions or equivalent to clean
wiper blades.
Change the wiper blades on your
vehicle at least once a year.
Cabin air filter replacement
In your climate control system, you
have a filter that cleans the air
before it enters the interior of the
vehicle. This filter should be
replaced at the intervals in the
“Scheduled Maintenance Guide“.
To replace the cabin air filter:
1. Unscrew the nut in the base of
each windshield wiper arm.
Remove the windshield wiper arms.

Maintenance and care
187 2. Remove the plastic caps from
the screws on the grille. Remove
the screws.
3. Open the hood. Pull off the
rubber weatherstrip at the back of
the engine compartment. Remove
the screws that hold the grille,
separate the two halves and
remove the grille.
4. The filter is in a housing at the
back of the engine compartment,
on the passenger side. Pull off the
two clips on the sides of the
housing. Slide out the top part of
the housing and filter.
5. Slide the filter out of the
housing, replace with the new filter
and slide the top part of the
housing and cabin air filter back
into place. Reinstall the clips on the
housing.
6. Replace the grille and wiper
arms.

Maintenance and care
188New 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
Regulation 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. INFORMATION ABOUT TIRE
QUALITY GRADES

Maintenance and care
189 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.
Those 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.
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.

Maintenance and care
190Temperature 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. 109. 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.

Maintenance and care
191 Checking tire pressure
Check the tire pressure
periodically after the vehicle has
been parked for at least one hour
or has been driven less than 5 km
(3 miles). Inflate the tires as
necessary. To check the tire
pressure, insert the tire pressure
gauge into the valve.
The cold pressure amount is listed
on the Safety Compliance
Certification label.
Improperly inflated tires can
affect vehicle handling and
can fail suddenly, possibly
resulting in loss of vehicle control.
Rotating tires
Rotate your tires at regular
intervals for even wear. Rotation
intervals are listed in the
“Scheduled Maintenance Guide”.

Maintenance and care
192
Failure to follow these
precautions may adversely
affect the handling of the vehicle
and make it easier to lose control
and roll over.
Replacing tires
Replace 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.
Do not replace your tires
with “high performance”
tires or larger size tires.
