Emission Control System
Your vehicle is equipped with a catalytic converter which enables
your vehicle to comply with applicable exhaust emission
requirements.
WARNING
Exhaust leaks may result in the entry of harmful and
potentially lethal fumes into the passenger compartment.
Under extreme conditions excessive exhaust
temperatures could damage the fuel system, the interior
floor covering, or other vehicle components, possibly
causing a fire.
Malfunctions in the engine or exhaust system can result in
excessive exhaust system temperatures. Under extreme conditions
(for example, towing a trailer up a steep hill on a very hot day
with a malfunctioning engine or exhaust system), high exhaust
system temperatures could be damaging.
To make sure that the catalytic converter and the other emission
control parts continue to work properly:
mUse only unleaded fuel.
mAvoid running out of fuel.
mNever turn off the ignition while your vehicle is moving,
especially at high speeds.
mHave the services listed in yourMaintenance Schedulebooklet
performed according to the specified schedule.

WARNING
Do not park, idle, or drive your vehicle in dry grass or
other dry ground cover. The emission system heats up the
engine compartment and exhaust system, which can
start a fire.
WARNING
Do not remove the floor carpet in your vehicle. Emission
controls cause high exhaust temperatures under the
floor.
Watch for fluid leaks, strange odors, smoke and loss of oil
pressure. Also watch for the charge warning light, the check engine
light, or the temperature warning light. These sometimes
indicate that the emission system is not working properly.
Do not make any unauthorized changes to your vehicle or engine.
Changes that cause more unburned fuel to reach the exhaust
system can increase the temperature of the engine or exhaust
system.
In general, maintenance, replacement, or service of the emission
control devices or systems in your new Ford Motor
Company vehicle or engine may be performed at your expense
by any automotive repair establishment or individual using
automotive parts equivalent to those with which your vehicle or
engine was originally equipped.
By law, anyone who manufactures, repairs, services, sells, leases
vehicles, trades vehicles, or supervises a fleet of vehicles is
not permitted to intentionally remove an emission control device
or prevent it from working. In some of the United States and
in Canada, vehicle owners may be liable if their emission control
device is removed or is prevented from working.

Do not drive your vehicle if it does not operate properly. See
your dealer if the engine runs on for more than five seconds after
you shut it off or if it misfires, surges, stalls, or backfires.
Information about your vehicle's emissions control system is on
the Vehicle Emission Control Information decal located on or
near the engine. This decal identifies engine displacement and gives
some tune-up specifications.
How to Prepare Your Vehicle for
Inspection/Maintenance (I/M) Testing
In some localities it may be a legal requirement to pass an I/M
test of the on-board diagnostic (OBD-II) system. If your``Service
Engine Soon''light is on, reference the applicable light
description in the Warning Light and Gauges section of your
owners guide. Your vehicle may not pass the I/M test with the
``Service Engine Soon''light on.
If the vehicles powertrain system or battery has just been
serviced, the OBD-II system is reset to a ``not ready for I/M test''
condition. To ready the OBD-II system for I/M testing, a
minimum of 30 minutes of city and highway driving is necessary
as described below:
mFirst, at least ten minutes of driving on an expressway or
highway.
mNext, at least twenty minutes of driving in stop-and-go,
city-type driving with at least four idle periods.
Allow the vehicle to sit for at least 8 hours without starting the
engine. Then, start the engine and complete the above driving cycle.
The engine must warm up to it's normal operating
temperature. Once started, do not turn off the engine until the
above driving cycle is complete.

WARNING
Handle a halogen headlamp bulb carefully and keep out
of children's reach. Grasp the bulb only by its plastic
base and do not touch the glass. The oil from your hand
could cause the bulb to break the next time the headlamps
are operated.
Do not remove the burned out bulb unless you can immediately
replace it with a new one. If a bulb is removed for an
extended period of time, contaminants may enter the headlamp
and affect its performance.
Removing the headlamp bulb
1. Make sure that the engine is off and the headlamp switch on
the instrument panel is in the OFF position.
2. Remove the electrical connector from the bulb by pulling the
connector away from the bulb assembly.

Cleaning the Engine
A clean engine is more efficient because a buildup of grease and
dirt acts as an insulator, keeping the engine warmer than
normal.
mExtreme care must be used if a power washer is used to clean
the engine. The high pressure fluid could penetrate sealed
parts and assemblies causing damage or malfunctions.
mIn order to avoid possible cracking of the engine block, do not
spray a hot engine with cold water.
mThe alternator, distributor and air intake must be covered.
Covering these components will help prevent water
damage.
mNever wash or rinse the engine while it is running. Water
getting into the engine may cause internal damage.
Maintenance and Care

Engine
mStart the engine every 15 days. Run it at fast idle until it
reaches normal operating temperature.
mWith your foot on the brake, shift the transaxle into all gears
while the engine is running.
Fuel system
mFill fuel tank with high-quality unleaded fuel until the first
automatic shutoff of the fuel pump nozzle.
NOTE: During extended periods of vehicle storage (60 days or
more), fuel may deteriorate due to oxidation. This can
damage rubber and other polymers in the fuel system
and may also clog small orifices.
Ford Gas Stabilizer should be added whenever actual or expected
storage periods exceed 60 days. Follow the instructions on the
label. The vehicle should then be operated at idle speed to circulate
the additive throughout the fuel system.
A volatile corrosion inhibitor added to the fuel system will
protect the fuel system's inner surfaces from corrosion. Follow
the instructions packaged with the product.
