ENGINE COOLANT
Checking engine coolant
•Check the level of engine coolant
when the engine is cold.
•The coolant should be at the
“cold fill level”or with the“cold
fill range”as listed on the engine
coolant reservoir.
•Refer to theScheduled
Maintenance Guidefor service
interval schedules.
Make sure to use a 50/50 mixture of engine coolant and distilled water.
Do not add engine coolant when the engine is hot. Steam and
scalding liquids released from a hot cooling system can burn you.
You can also be burned if you spill coolant on hot engine parts.
Do not put engine coolant in the windshield washer fluid
container. If sprayed on the windshield, engine coolant could
make it difficult to see through the windshield.
Note:Automotive fluids are not interchangeable; do not use engine
coolant, antifreeze or windshield washer fluid outside of its specified
function.
For vehicles with overflow coolant systems with a non-pressurized cap
on the coolant recovery system, add coolant to the recovery reservoir
when the engine is cool. Add the proper 50/50 coolant mixture to the
“cold full”level. For all other vehicles, follow these steps to add engine
coolant.
1. Turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the coolant
pressure relief cap on the reservoir. Slowly turn the cap
counterclockwise until pressure begins to release.

FFV engine (if equipped)
Flexible fuel vehicle (FFV) fuel tanks may contain 0 to 85 percent or
more of ethnanol. Any fuel blends containing gasoline and ethanol should
be treated the same as“Fuel Ethanol (E85).”To identify if your vehicle
is an FFV, check your VIN or the label on the inside of your fuel filler
door. When checking your VIN, the engine type identifier (8th character)
is“K.”
If you have a flex fuel vehicle, use only UNLEADED FUEL and
ETHANOL (E85).
Note:Flexible fuel components and standard unleaded fuel components
are NOT interchangeable. If your vehicle is not serviced in accordance
with flexible fuel vehicle procedures, damage may occur and your
warranty may be invalidated.
U.S. government regulations require fuel ethanol dispensing
pumps to have a small, square, orange and black label with the
common abbreviation E85 or the appropriate percentage for that
region. Use of other fuels such as Fuel Methanol may cause power
train damage, a loss of vehicle performance, and your warranty
may be invalidated.
Fuel quality
The World-wide Fuel Charter
recommends gasoline specifications
to provide improved performance
and emission control system
protection. Ask your fuel supplier
about gasolines that meet the
World-wide Fuel Charter. In Canada,
look for fuels that display theAuto
Makers’Choice
logo.
It should not be necessary to add
any aftermarket products to your
fuel tank if you use high quality fuel of the recommended octane rating.
Aftermarket products could cause damage to the fuel system and
invalidate your warranty.
Cleaner air
Ford endorses the use of reformulated“cleaner-burning”gasolines to
improve air quality.
Maintenance and Specifications
153

Keep a record for at least one month and record the type of driving (city
or highway). You can also keep records in summer and winter to
determine how temperature impacts fuel economy. Note that ethanol
decrease fuel economy.
Improving fuel economy
To improve your fuel economy:
•Do not leave your vehicle idling for long periods of time.
•Drive at a moderate pace, with smooth acceleration and deceleration.
•Turn off speed control in hilly terrain.
•Follow the recommended maintenance schedule in yourScheduled
Maintenance Guide.
•Do not carry unnecessary weight.
EPA window sticker
The EPA window sticker should be your guide for fuel economy
comparisons. If you have any questions about this sticker, contact your
dealer.
EMISSION CONTROL SYSTEM
Your vehicle has emission control components and a catalytic converter
that enable your vehicle to comply with applicable exhaust emission
standards. To make sure that the emission control components work
properly:
•Use only unleaded fuel.
•Avoid running out of fuel.
•Do not turn off your ignition while the vehicle is moving.
•Follow yourScheduled Maintenance Guide.
•Use Ford Motor Company authorized parts for maintenance
replacements or for service.
Consult yourWarranty Guidefor emission warranty information.
Do not park, idle, or drive your vehicle in dry ground cover. The
emission system heats up the engine and exhaust system, which
could cause a fire.
Maintenance and Specifications
156

The following signs could indicate a problem with your emission control
system:
•Fluid leaks
•Strange odors
•Smoke
•Loss of engine power
•Illumination of the charging system, temperature, or“Check Engine”
light in the instrument panel.
Exhaust leaks may result in harmful and potentially lethal fumes
entering the passenger compartment.
It is unlawful 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.
READINESS FOR INSPECTION/MAINTENANCE (I/M) TESTING
It may be a legal requirement in your area to pass an I/M test of the
on-board diagnostics system. If the system or battery has just been
serviced, the on-board diagnostic system is reset to a“not ready for I/M
test”condition. To ready the system, allow the vehicle to sit for at least
eight hours without starting. Then, start the engine and complete the
following driving cycle:
1. Drive on an expressway or highway for at least 10 minutes.
2. Drive in stop-and-go traffic for at least 20 minutes with a minimum of
four idle periods.
The engine must warm up to its normal operating temperature. Once
started, do not turn off the engine until the above drive cycle is
complete.
Note:If your“Check Engine”light is on, your vehicle may not pass an
I/M test.

U.S. Department of Transportation-Tire quality grades:The U.S.
Department of Transportation requires Ford to give you the following
information about tire grades exactly as the government has written it.
Treadwear
The treadwear grade is a comparative rating based on the wear rate of
the tire when tested under controlled conditions on a specified
government test course. For example, a tire graded 150 would wear one
and one-half (1 1/2) times as well on the government course as a tire
graded 100. The relative performance of tires depends upon the actual
conditions of their use, however, and may depart significantly from the
norm due to variations in driving habits, service practices, and
differences in road characteristics and climates.
Traction AA A B C
The traction grades, from highest to lowest are AA, A, B, and C. The
grades represent the tire’s ability to stop on wet pavement as measured
under controlled conditions on specified government test surfaces of
asphalt and concrete. A tire marked C may have poor traction
performance.
The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not include
acceleration, cornering, hydroplaning or peak traction characteristics.
Temperature A B C
The temperature grades are A (the highest), B and C, representing the
tire’s resistance to the generation of heat and its ability to dissipate heat
when tested under controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to a level of performance
which all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by
law.
The temperature grade for this tire is established for a tire that
is properly inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either separately or in
combination, can cause heat buildup and possible tire failure.
