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.

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.
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.
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.

Calculating fuel economy
To accurately calculate your
vehicleÕs fuel economy:
1. Fill the tank completely and
record the initial odometer reading.
2. Each time you fill the tank,
record the amount of fuel added
(in litres or gallons).
3. After at least three to five fill-
ups, fill the fuel tank and record
the current mileage reading.
4. Use one of the following
equations to calculate fuel
economy.
Litres used x 100 / Total kilometres
traveled.
Total miles traveled / Total gallons
used.
Keep a record for at least one
month. This will provide an
accurate estimate of the vehicleÕs
fuel economy.

EMISSION CONTROL SYSTEM
Your vehicle is equipped with
various emission control
components and a catalytic
converter which will enable your
vehicle to comply with applicable
exhaust emission standards. To
make sure that the catalytic
converter and other emission
control components continue to
work properly:
¥ Use unleaded fuel only.
¥ Avoid running out of fuel.
¥ Do not turn off the ignition while
your vehicle is moving, especially
at high speeds.
¥ Have the items listed in your
maintenance guide and or service
guide performed according to the
specified schedule.
The scheduled maintenance
services listed in the maintenance
guide and or service guide are
required because they are
considered essential to the life and
performance of your vehicle and to
its emissions system.
If other than Ford, Motorcraft, or
Ford authorized parts are used for
maintenance replacements or for
service of components affecting
emissions control, such non-Ford
parts should be equivalent to
genuine Ford Motor Company parts
in performance and durability.

Watch for fluid leaks, strange
odors, smoke, loss of oil pressure,
engine overheating, illumination of
the charging systemwarning light
or the check enginewarning light.
These events could indicate that
the emission control system is not
working properly.
Exhaust leaks may result in
entry of harmful and
potentially lethal fumes into the
passenger compartment.
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.

Do not make any unauthorized
changes to your vehicle or engine.
By law, vehicle owners and anyone
who manufactures, repairs,
services, sells, leases, trades
vehicles, or supervises a fleet of
vehicles are not permitted to
intentionally remove an emission
control device or prevent it from
working. Information about your
vehicle's emission system is on the
Vehicle Emission Control
Information Decal located under
the hood. This decal identifies
engine displacement and gives
some tune up specifications.
Please consult your ÒWarranty
GuideÒ for complete emission
warranty information.
Readiness 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 check enginelight
is on, refer to the description in the
Instrument Cluster Lights and
Chimessection of the
Instrumentation chapter. Your
vehicle may not pass the I/M test
with the check engine light on.

If the vehicleÕs powertrain system
or its battery has just been
serviced, the OBD-II system is
reset to a Ònot ready for I/M testÒ
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:
¥ First, at least 10 minutes of
driving on an expressway or
highway.
¥ Next, at least 20 minutes of
driving in stop and go, city-type
traffic with at least four idle
periods.
Allow the vehicle to sit for at least
eight hours without starting the
engine. Then, start the engine and
complete the above driving cycle.
The engine must warm up to its
normal operating temperature.
Once started, do not turn off the
engine until the above driving cycle
is complete.

BULB REPLACEMENT
Handle a halogen headlamp
bulb carefully and keep out
of childrenÕs reach.Grasp the bulb
only by its plastic base and do not
