more pronounced. If the problems persist, see your dealer or a qualified
service technician.
It should not be necessary to add any aftermarket products to your fuel
tank if you continue to use high quality fuel of the recommended octane
rating. Aftermarket products could cause damage to the fuel system.
Repairs to correct the effects of using an aftermarket product in your
fuel may not be covered by your warranty.
Many of the world's automakers
issued the World-wide Fuel Charter
that recommends gasoline
specifications to provide improved
performance and emission control
system protection for your vehicle.
Gasolines that meet the World-wide
Fuel Charter should be used when
available. Ask your fuel supplier
about gasolines that meet the
World-wide Fuel Charter. In Canada,
look for fuels that display theAuto Makers' Choiceylogo.
Cleaner air
Ford endorses the use of reformulated ªcleaner-burningº gasolines to
improve air quality.
Running out of fuel
Avoid running out of fuel because this situation may have an adverse
affect on powertrain components.
If you have run out of fuel:
²You may need to cycle the ignition from OFF to ON several times after
refueling, to allow the fuel system to pump the fuel from the tank to
the engine.
²Your ªCheck Engineº indicator may come on. For more information on
the ªCheck Engineº indicator, refer to theInstrumentationchapter.
Fuel Filter
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.
Maintenance and care
203

²Sudden or hard accelerations may reduce fuel economy.
²Slow down gradually.
²Driving at reasonable speeds (traveling at 88 km/h [55 mph] uses 15%
less fuel than traveling at 105 km/h [65 mph]).
²Revving the engine before turning it off may reduce fuel economy.
²Using the air conditioner or defroster may reduce fuel economy.
²
You may want to turn off the speed control in hilly terrain if
unnecessary shifting between third and fourth gear occurs. Unnecessary
shifting of this type 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.
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.
²Carrying unnecessary weight may reduce fuel economy (approximately
0.4 km/L [1 mpg] is lost for every 180 kg [400 lb] of weight carried).
²Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
²Using fuel blended with alcohol may lower fuel economy.
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.
Maintenance and care
206

Illumination of the ªCheck Engineº light, charging system warning light
or the temperature warning light, fluid leaks, strange odors, smoke or
loss of engine power, 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. Information about your vehicle's emission 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.
Please consult yourWarranty Guidefor 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 diagnostics system. If your ªCheck Engine/Service Engine
Soonº light is on, refer to the description in theWarning lights and
chimessection of theInstrumentationchapter. Your vehicle may not
pass the I/M test with the ªCheck Engine/Service Engine Soonº light on.
If the vehicle's powertrain system or its battery has just been serviced,
the on-board diagnostics system is reset to a ªnot ready for I/M testº
condition. To ready the on-board diagnostics system for I/M testing, a
minimum of 30 minutes of city and highway driving is necessary as
described below:
²First, at least 10 minutes of driving on an expressway or highway.
²Next, at least 20 minutes 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.
