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.
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.

Running out of fuel
Avoid running out fuel because this situation may
have an adverse affect on modern powertrain
components.
If you have run out of fuel:
²You may need to crank the engine several times
before the system starts to pump fuel from the
tank to the engine.
²Your ªService Engine Soonº light may come on.
For more information on the ªService Engine
Soonº light, refer to theInstrumentationchapter.
Fuel Filter
Your vehicle is equipped with a fuel filter that is
mounted on the underbody.
For fuel filter replacement, see your dealer or a
qualified service technician. Refer to the Scheduled
Maintenance Guide for the appropriate intervals for
changing the fuel filter.
If you replace the fuel filter, replace it with an
authorized Motorcraft part. The customer
warranty may be void for any damage to the
fuel system if an authorized Motorcraft fuel
filter is not used.
ESSENTIALS OF GOOD FUEL ECONOMY
Measuring techniques
Your best source of information about actual fuel
economy is you, the driver. You must gather
information as accurately and consistently as
possible. Fuel expense, frequency of fillups or fuel
gauge readings are NOT accurate as a measure of
fuel economy. We do not recommend taking fuel
economy measurements during the first 1 600 km (1
000 miles) of driving (engine break-in period). You
will get a more accurate measurement after 3 000
km±5 000 km (2 000 miles-3 000 miles).
Maintenance and care

²Drive at reasonable speeds (traveling at 105 km/h
[65 mph] uses 15% more fuel than traveling at
88 km/h [55 mph]).
²Revving the engine before turning it off may
reduce fuel economy.
²Use of the air conditioner or defroster may reduce
fuel economy.
²Use of speed control (if equipped) may improve
fuel economy. Speed control can help maintain a
constant speed and reduce speed changes. You
may want to turn off the speed control in hilly
terrain as unnecessary shifting between third and
fourth gears may occur and could result in
reduced fuel economy.
²Warming up a vehicle on cold mornings is not
required and may reduce fuel economy.
²Resting your foot on the brake pedal while driving
may reduce fuel economy.
²Combine errands and minimize stop-and-go
driving.
Maintenance
²Keep tires properly inflated and use only
recommended size.
²Operating a vehicle with the wheels out of
alignment will reduce fuel economy.
²Use recommended engine oil. Refer toLubricant
Specifications.
²Perform all regularly scheduled maintenance
items. Follow the recommended maintenance
schedule and owner maintenance checks found in
your vehicle Scheduled Maintenance Guide.
Conditions
²Heavily loading a vehicle or towing a trailer may
reduce fuel economy at any speed.
Maintenance and care
165

²Use only unleaded fuel.
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 emission control,
such non-Ford parts should be equivalent to genuine
Ford Motor Company parts in performance and
durability.
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.
Illumination of the charging system warning light,
ªService Engine Soonº light or the temperature
warning light, fluid leaks, strange odors, smoke or
loss of oil pressure, 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 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.

2Ensure correct automatic transmission fluid is used
for a specific application. Check the container to
verify the fluid is MERCONtand/or MERCONtV
approved. Some fluids have been approved as
meeting both MERCONtand MERCONtV
requirements and will be labeled as such. Fluids
labeled as meeting only MERCONtor only
MERCONtV requirements must not be used
interchangeably. DO NOT mix MERCONtand
MERCONtV. Transmission fluid requirements are
indicated on the dipstick or on the dipstick handle.
Refer to your Scheduled Maintenance Guide to
determine the correct service interval.
