2002 FORD EXPEDITION fuel pressure

5. Restart the engine and take your vehicle to a service facility.
Driving the vehicle without repairing the engine problem
increases the chance of engine damage. Take your vehicle to a
service facility as soon as possible.
WHAT YOU SHOULD KNOW ABOUT AUTOMOTIVE FUELS
Important safety precautions
Do not overfill the fuel tank. The pressure in an overfilled tank
may cause leakage and lead to fuel spray and fire.
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.
If you do not use the proper fuel filler cap, excessive pressure or
vacuum in the fuel tank may damage the fuel system or cause
the fuel cap to disengage in a collision, which may result in possible
personal injury.
Automotive fuels can cause serious injury or death if misused or
mishandled.
Gasoline may contain benzene, which is a cancer-causing agent.

personal injury.
Choosing the right fuel
Use only UNLEADED FUEL. The use of leaded fuel is prohibited by law
and could damage your vehicle.
Do not use fuel containing methanol. It can damage critical fuel system
components.
Your vehicle was not designed to use fuel or fuel additives with metallic
compounds, including manganese-based compounds containing MMT.
Repairs to correct the effects of using a fuel for which your vehicle was
not designed may not be covered by your warranty.
Octane recommendations
Your vehicle is designed to use
ªRegularº unleaded gasoline with
pump (R+M)/2 octane rating of 87.
We do not recommend the use of
gasolines labeled as ªRegularº that
are sold with octane ratings of 86 or lower in high altitude areas.
Do not be concerned if your engine sometimes knocks lightly. However, if
it knocks heavily under most driving conditions while you are using fuel
with the recommended octane rating, see your dealer or a qualified
service technician to prevent any engine damage.
Fuel quality
If you are experiencing starting, rough idle or hesitation driveability
problems during a cold start, try a different brand of ªRegularº unleaded
gasoline. ªPremiumº unleaded gasoline is not recommended (particularly
in the United States) because it may cause these problems to become

²Fuel economy may decrease with lower temperatures during the first
12±16 km (8±10 miles) of driving.
²Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
²Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
²Four-wheel-drive operation (if equipped) is less fuel efficient than
two-wheel-drive operation.
²Close windows for high speed driving.
EPA window sticker
Every new vehicle should have the EPA window sticker. Contact your
dealer if the window sticker is not supplied with your vehicle. The EPA
window sticker should be your guide for the fuel economy comparisons
with other vehicles.
It is important to note the box in the lower left corner of the window
sticker. These numbers represent the Range of L/100 km (MPG)
expected on the vehicle under optimum conditions. Your fuel economy
may vary depending upon the method of operation and conditions.
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:
²Use only the specified fuel listed.
²Avoid running out of fuel.
²Do not turn off the ignition while your vehicle is moving, especially at
high speeds.
²Have the items listed in your scheduled maintenance guide performed
according to the specified schedule.
The scheduled maintenance items listed in the scheduled maintenance
guide are 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

SERVICING YOUR TIRES
Checking the tire pressure
²Use an accurate tire pressure gauge.
²Check the tire pressure when tires are cold, after the vehicle has been
parked for at least one hour or has been driven less than 5 km (3
miles).
²Adjust tire pressure to recommended specifications found on the
Certification Label. Tire pressure information can also be found on the
Tire Information label located on the inside of the fuel filler door.
Improperly inflated tires can affect vehicle handling and can fail
suddenly, possibly resulting in loss of vehicle control.
Tire rotation
Because your vehicle's tires perform different jobs, they often wear
differently. To make sure your tires wear evenly and last longer, rotate
them as indicated in the scheduled maintenance guide. If you notice that
the tires wear unevenly, have them checked.
²Four tire rotation
