WARNINGS
Keep batteries out of reach of
children. Batteries contain sulfuric
acid. Avoid contact with skin, eyes or
clothing. Shield your eyes when working
near the battery to protect against possible
splashing of acid solution. In case of acid
contact with skin or eyes, flush
immediately with water for a minimum of
15 minutes and get prompt medical
attention. If acid is swallowed, call a
physician immediately.
Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash hands after
handling.
This vehicle may be fitted with more
than one battery. Removing the
battery cables from only one battery
does not disconnect your vehicle electrical
system. Make sure you disconnect the
battery cables from all batteries when
disconnecting power. Failure to do so may
cause serious personal injury or property
damage.
Your vehicle is fitted with a Motorcraft
maintenance-free battery which normally
does not require additional water.
When a battery replacement is required,
you must use a recommended
replacement battery that matches the
electrical requirements of the vehicle.
Note: After cleaning or replacing the
battery, make sure you reinstall the battery
cover or shield.
Note: If you add electrical accessories or
components to the vehicle, it may adversely
affect the low voltage battery performance
and durability. This may also affect the
performance of other electrical systems in
the vehicle.
For longer, trouble-free operation, keep the
top of the battery clean and dry.

Maintenance
If you see any corrosion on the battery or
terminals, remove the cables from the
terminals and clean with a wire brush. You
can neutralize the acid with a solution of
baking soda and water.
Because your vehicle's engine is
electronically controlled by a computer,
some control conditions are maintained
by power from the battery. When the
battery is disconnected or a new battery
is installed, the engine must relearn its idle
and fuel trim strategy for optimum
driveability and performance. Flexible fuel
vehicles (FFV) must also relearn the
ethanol content of the fuel for optimum
driveability and performance.
To restore the settings, do the following:
1. Apply the parking brake.
2. Shift into park (P) or neutral (N).
3. Switch off all accessories.
4. Press the brake pedal and start your
vehicle.
5. Run the engine until it reaches normal
operating temperature. While the
engine is warming up, complete the
following: Reset the clock. See Audio
System (page 312). Reset the power
windows bounce-back feature. See
Windows and Mirrors (page 80).
Reset the radio station presets. See
Audio System (page 312).
6. Allow the engine to idle for at least one
minute.
7. Drive the vehicle at least 10 mi (16 km)
to completely relearn the idle trim and
fuel trim strategy.
Note: If you do not allow the engine to
relearn the idle and fuel trim strategy, the
idle quality of your vehicle may be adversely
affected until the engine computer
eventually relearns the idle trim and fuel
