will not effect function or durability of the
transmission. Over time, the adaptive learning
process will fully update transmission operation to
its optimum shift feel.
1.Use only a 12±volt supply to start your
vehicle.
2. Do not disconnect the battery of the disabled
vehicle as this could damage the vehicle's electrical
system.
3. Park the booster vehicle close to the hood of the
disabled vehicle making sure the two vehiclesdo
nottouch. Set the parking brake on both vehicles
and stay clear of the engine cooling fan and other
moving parts.
4. Check all battery terminals and remove any
excessive corrosion before you attach the battery
cables.
5. Turn the heater fan on in both vehicles to protect
any electrical surges. Turn all other accessories off.
Connecting the jumper cables
1. Connect the positive (+) booster cable to the
positive (+) terminal of the discharged battery.

SERVICE RECOMMENDATIONS
To help you service your vehicle:
²We highlight do-it-yourself items in the engine
compartment for easy location.
²We provide a scheduled maintenance guide which
makes tracking routine service easy.
If your vehicle requires professional service, your
dealership can provide the necessary parts and
service. Check yourWarranty Guideto find out
which parts and services are covered.
Use only recommended fuels, lubricants, fluids and
service parts conforming to specifications. Motorcraft
parts are designed and built to provide the best
performance in your vehicle.
PRECAUTIONS WHEN SERVICING YOUR
VEHICLE
Be especially careful when inspecting or servicing
your vehicle.
²Do not work on a hot engine.
²When the engine is running, keep loose clothing,
jewelry or long hair away from moving parts.
²Do not work on a vehicle with the engine running
in an enclosed space, unless you are sure you
have enough ventilation.
²Keep all lit cigarettes, open flames and other lit
material away from the battery and all fuel related
parts.
If you disconnect the battery, the engine must
ªrelearnº its idle conditions before your vehicle will
drive properly, as explained in theBatterysection in
this chapter.
Working with the engine off
²Automatic transmission:
1. Set the parking brake and ensure the gearshift is
securely latched in P (Park).

WINDSHIELD WASHER FLUID
Washer fluid
Check the washer fluid
whenever you stop for
fuel. The reservoir is
highlighted with a
symbol.
If the level is low, add
enough fluid to fill the
reservoir. In very cold
weather, do not fill the
reservoir all the way.
Only use a washer fluid that meets Ford
specification . Refer toLubricant specificationsin
theCapacities and specificationschapter.
State or local regulations on volatile organic
compounds may restrict the use of methanol, a
common windshield washer antifreeze additive.
Washer fluids containing non-methanol antifreeze
agents should be used only if they provide cold
weather protection without damaging the vehicle's
paint finish, wiper blades or washer system.
Do not put washer fluid in the engine coolant
reservoir. Washer fluid placed in the cooling
system may harm engine and cooling system
components.
ENGINE COOLANT
Checking engine coolant
The concentration and level of engine coolant should
be checked at the mileage intervals in the scheduled
maintenance guide. The coolant concentration
should be maintained at 50/50 coolant and water,
which equates to a freeze point of -36É C (-34É F).
Coolant concentration testing is possible with a
hydrometer or antifreeze tester (such as the
Rotunda Battery and Antifreeze Tester, 014±R1060).

ªCheck Fuel Capº illuminates when the ignition is
turned to the ON position to ensure your bulb is
working. When this light turns on, check the fuel
filler cap. Continuing to operate the vehicle with the
Check Fuel Cap light on, can activate the Service
Engine Soon warning. When the fuel filler cap is
properly re-installed, the light(s) will turn off after a
period of normal driving.It may take a long
period of time for the system to detect an
improperly installed fuel filler cap.
If you must replace the fuel filler cap, replace
it with a fuel filler cap that is designed for
your vehicle. The customer warranty may be
void for any damage to the fuel tank or fuel
system if the correct genuine Ford or
Motorcraft fuel filler cap is not used.
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.
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.
Maintenance and care
183

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.
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.
²Transmissions give their best fuel economy when
operated in the top cruise gear and with steady
pressure on the gas pedal.
²Close windows for high speed driving.
Maintenance and care
189

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 ªService Engine Soonº 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 theInstrumentation
chapter. Your vehicle may not pass the I/M test with
the ªCheck Engine/Service Engine Soonº light on.
