Do not attempt to push-start your vehicle.
Automatic transmissions do not have
push-start capability; also, the catalytic
conveter may become damaged.
Preparing your vehicle
When the battery is disconnected or a new battery is
installed, the transmission must relearn its adaptive
strategy. As a result of this, the transmission may
shift firmly. This operation is considered normal and
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 not
touch. 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. Ensure the vent caps are tight and level.
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

BATTERY
Your vehicle is
equipped with a
Motorcraft
maintenance-free
battery which normally
does not require
additional water during
its life of service.
However, for severe usage or in high temperature
climates, check the battery electrolyte level. Refer to
the scheduled maintenance guide for the service
interval schedules.
Keep the electrolyte level in each cell up to the
ªlevel indicatorº. Do not overfill the battery
cells.
If the electrolyte level in the battery is low, you can
add plain tap water to the battery, as long as you do
not use hard water (water with a high mineral or
alkali content). If possible, however, try to only fill
the battery cells with distilled water. If the battery
needs water often, have the charging system
checked.
If your battery has a cover/shield, make sure it
is reinstalled after the battery has been
cleaned or replaced.
For longer, trouble-free operation, keep the top of
the battery clean and dry. Also, make certain the
battery cables are always tightly fastened to the
battery terminals.

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).
The level of coolant should be maintained at the
ªcold fullº of ªcold fill rangeº level in the coolant
reservoir. If the level falls below, add coolant per the
instructions in theAdding Engine Coolantsection.
Your vehicle was factory-filled with a 50/50 engine
coolant and water concentration. If the
concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not
work properly.A 50±50 mixture of coolant and
water provides the following:
²freeze protection down to -36É C (-34É F)
²boiling protection up to 129É C (265É F)
²protection against rust and other forms of
corrosion
²enables calibrated gages to function properly

Adding engine coolant
When adding coolant, make sure it is a 50/50
mixture of engine coolant and distilled water. Add
the mixture to the coolant reservoir,when the
engine is cool, until the appropriate fill level is
obtained.
Do not add engine coolant when the engine
is hot. Steam and scalding liquids released
from a hot cooling system can burn you badly.
Also, you can 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.
The cooling system in your vehicle is filled with
either green-colored Motorcraft Premium Engine
Coolant meeting Ford specification ESE-M97B44±A
or yellow-colored Motorcraft Premium Gold Engine
Coolant meeting Ford Specification
