141 Automatic transaxle fluid
Check the automatic transaxle fluid
according to the scheduled
intervals in the “Service Guide”.
However, if the transaxle is not
working properly (slipping, shifting
slowly or fluid leakage) the fluid
level should be checked.
Adding automatic transaxle
fluid
Before adding any fluid, make sure
the correct type will be used. This
information is stamped on the
dipstick.
Check the fluid after your vehicle
has reached normal operating
temperature, which is reached
after driving approximately 32 km
(20 miles).
Add fluid in 0.25 litre (0.5 pint)
increments through the filler tube
until the fluid is at the correct level
on the dipstick. If an overfill
occurs, excess fluid should be
removed by your dealer or a
qualified service technician.

MotorcraftSUPERSTART
Pb
Battery
Your vehicle may be equipped with
a Motorcraft maintenance-free
battery. The Motorcraft
maintenance-free battery normally
does not require additional water
during its life of service. However,
for severe service usage or in high
temperature climates, check your
battery electrolyte level, at least
every 24 months or 40 000 km
(24 000 miles). Keep the
electrolyte in each cell up to the
“level” indicator. Do not overfill the
battery cell.
For longer, trouble-free operation,
keep the top of the battery clean
and dry. Also, make certain the
battery cables are always tightly
fastened to the battery terminals.
If you see any corrosion on the
battery cables or terminals, remove
the cables from the terminal(s) and
clean with a wire brush. You can
neutralize the acid with a solution
of baking soda and water. Reinstall
the cables when you are done
cleaning them, and apply a small
quantity of grease to the top of
each battery terminal to help
prevent corrosion.

Maintenance and care
144Battery replacement
If your original equipment battery
requires replacement while under
warranty, it will be replaced with a
Motorcraft service battery,
identical in design technology. Like
the original equipment battery, it
should not require water addition
during its normal life of service;
however, for severe service usage
or in high temperature climates,
check your battery electrolyte
level, at least every 24 months or
40 000 km (24 000 miles). Do not
overfill the battery cell.
If the electrolyte level in your
battery gets low, you can add plain
tap water to the battery, as long as
you do not use hard water (water
with a high mineral or alkali
content). If possible, however, try
to only fill the battery cell with
distilled water. If the battery needs
water often, have the charging
system checked.

Maintenance and care
150Treadwear
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 of 150
would wear one and one-half
(11/2) times as well on the
government course as a tire grade
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 ABC
The traction grades, from highest
to lowest are A, B, and C, and they
represent the tire’s ability to stop
on wet pavement as measured
under 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
braking (straightahead) traction
tests and does not include
cornering (turning) traction.

Maintenance and care
152Checking tire pressure
Check the tire pressure
periodically and 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 “Service
Guide”.

Maintenance and care
154
Dispose of worn tires in
accordance with local
environmental regulations.
Refer to the Safety Compliance
Certification label to determine the
specific size tire and wheel Ford
Motor Company recommends for
use on this vehicle.
When purchasing replacement tires
for your vehicle, consult your
dealer or a qualified service
technician to ensure that the
correct tire type is used.

Maintenance and care
155 The tires on your vehicle have all-
weather treads to provide traction
in rain and snow. However, in some
climates, using snow tires and
chains may be necessary. Ford
offers snow chains as a Ford
approved accessory and
recommends use of these or their
equivalents on approved tires. See
your dealer or a qualified service
technician for more information on
tire chains for your vehicle. Follow
these guidelines when using snow
tires and chains:
•Install chains securely, verifying
that the chains do not touch any
wiring, brake lines or fuel lines.
•Install the chains on the front
tires only.
•Do not use tire chains 205/60
tires and 205/55R16 Z rated tires.
Steering, suspension and body
components may be damaged by
use of chains.
Snow tires must be the same
size and grade as the tires
you currently have on your
vehicle.

Maintenance and care
160Octane recommendations
Your vehicle is designed to use
regular gasoline with an (R+M)/2
octane rating of 87. We do not
recommend gasolines labeled as
“regular” in high altitude areas that
are sold with octane ratings of 86
or even less.
Do not be concerned if your vehicle
sometimes knocks lightly. However,
if it knocks heavily under most
driving conditions on the
recommended octane, see your
dealer or a qualified service
technician to prevent any engine
damage.
