Automatic transaxle fluid
Follow the scheduled service
intervals outlined in the
maintenance guide and or service
guide.
Before adding any fluid, make sure
the correct type is used. The type
of fluid used is normally indicated
on the dipstick and/or dipstick
handle and also in the
Lubricant
specifications
section in the
Capacities and specifications
chapter.
Do not drive the vehicle if the fluid
level is below the hole at the
bottom of the dipstick and outside
temperatures are above 10¡C
(50¡F).
Your transaxle does not use up
fluid. However, it is recommended
that you check the transaxle fluid
at least twice a year. The fluid level
should be checked if the transaxle
is not working properly, i.e., if the
transaxle slips or shifts slowly or if
you notice some sign of fluid
leakage.
Transaxle fluid should be checked
at normal operating temperatures
of 66¡C - 77¡C (150¡F - 170¡F) on a
level surface while the engine is
running in the P (Park) gearshift
lever position. The normal
operating temperature can be
reached after approximately 32 km
(20 miles) of driving.

The transaxle fluid should be in
this range if at normal operating
temperature 66¡C - 77¡C
(150¡F - 170¡F).
The transaxle fluid should be in
this range if at room temperature
10¡C - 35¡C (50¡F - 95¡F).
If the vehicle has been operated for
an extended period at high speeds,
in the city during hot weather or
pulling a trailer, the vehicle should
be turned off for about thirty
minutes to allow the fluid to cool
before checking.
1. Park the vehicle on a level
surface and engage the parking
brake.
2. With the parking brake engaged
and your foot on the brake pedal,
start the engine and move the
gearshift lever through all of the
gear ranges. Allow sufficient time
for each gear to engage.
3. Latch the gearshift lever in
P (Park) and leave the engine
running.
4. Remove the dipstick, wiping it
clean with a clean, dry lint free rag.
5. Install the dipstick making sure
it is fully seated in the filler tube.

Relearning the idle function
Because your vehicleÕs 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 ÒrelearnÓ 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 ÒrelearningÓ process will
automatically complete as you
drive the vehicle.
¥ If you do not allow the engine to
ÒrelearnÓ its idle, the idle quality of
your vehicle may be adversely
affected until the idle is eventually
ÒrelearnedÓ.
¥ 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.

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.

Observe the following guidelines
when handling automotive fuel:
¥ Extinguish all smoking materials
and any open flames before fueling
your vehicle.
¥ Always turn off the vehicle
before fueling.
¥ Make sure the fuel cap is
correctly fitted after fueling.
Failure to do so may cause the on
board diagnostic system to
illuminate the CHECK ENGINE
light.
¥ Automotive fuels can be harmful
or fatal if swallowed. If fuel is
swallowed, call a physician
immediately, even if no symptoms
are immediately apparent. The
toxic effects of fuel may not be
visible for hours.
¥ Fuels can also be harmful if
absorbed through the skin. If fuel is
splashed on the skin, promptly
remove contaminated clothing and
wash skin thoroughly with soap
and water.
¥ If fuel is splashed in the eyes,
remove contact lenses (if worn),
flush with water for 15 minutes and
seek medical attention.
¥ Be particularly careful if you are
taking ÒAntabuseÓ or other forms of
disulfiram for the treatment of
alcoholism. Breathing gasoline
vapors or skin contact could cause
an adverse reaction. Consult a
physician immediately.

Choosing the right fuel
Use only UNLEADED FUEL. The
use of leaded fuel is prohibited by
law and could damage your vehicle.
The damage may not be covered by
your warranty.
Your vehicle was not designed to
use fuel containing manganese-
based additives such as MMT.
Additionally, vehicles certified to
California emission standards
(indicated on the underhood
Vehicle Emission Control
Information label) are designed to
operate on California reformulated
gasolines. If California reformulated
gasoline is not available when you
refuel, your vehicle can be
operated on non-California fuels.
However, even though your engine
will perform adequately on other
gasolines, the performance of the
emission control devices and
systems may be adversely affected.
Repair of damage caused by a fuel
that your vehicle was not designed
for may not be covered by your
warranty.

Octane 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
ÒregularÓ 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.

MINIMUM OCTANE RATING
(R+M)/2 Method
Fuel quality
If you are experiencing starting,
rough idle or hesitation problems
try a different brand of fuel. If the
condition persists, see your dealer
or qualified service technician.
The American Automobile
Manufacturers Association
(AAMA) issued a gasoline
specification to provide information
on high quality fuels that optimize
the performance of your vehicle.
We recommend the use of gasolines
that meet the AAMA specification
if they are available.
It should not be necessary to add
any aftermarket products to your
fuel tank if you continue to use a
high-quality fuel.

Fuel filler cap
If the Òcheck engineÓ indicator
comes on and stays on when you
start the engine, the fuel filler cap
may not be properly installed. Turn
off the engine, remove the fuel
filler cap and reinstall it being
careful to align the cap properly.
If you must replace the fuel
filler cap, replace it with an
authorized Motorcraft part.
The customer warranty may be
void for any damage to the fuel
tank or fuel system if an
authorized Motorcraft fuel
filler cap is not used.
The fuel system may be
under pressure. If the fuel
filler cap is venting vapor or if you
hear a hissing sound, wait until it
stops before completely removing
the fuel filler cap. Otherwise fuel
may spray out and injure you or
others.
Cleaner air
Ford approves the use of gasolines
to improve air quality, including
reformulated gasolines that contain
oxygenates such as a maximum of
10% ethanol or 15% MTBE. There
should be no more than 5%
methanol with cosolvents and
additives to protect the fuel
system.
