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.
When a battery replacement is
required, the battery should only be
replaced with a Ford recommended
replacement battery that matches
the electrical requirements of the
vehicle.
Because your vehicle’s engine is
electronically-controlled by a
computer, some engine control
settings are maintained by power
from the low voltage battery. Some
engine computer settings, like the idle
trim and fuel trim strategy, optimize
the driveability and performance of
the engine. Some other computer
settings, like the clock and radio
station presets, are also maintained
in memory by power from the low
voltage battery. When a technician
disconnects and connects the low
voltage battery, these settings are
erased. Complete the following
procedure in order to restore the
settings:
1. With the vehicle at a completestop, set the parking brake.
2. Shift the transmission into P.
3. Turn off all accessories.
4. Step on the brake pedal and start the 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
124). Reset the power windows
bounce-back feature. See
Windows and Mirrors (page 88).
Reset the radio station presets.
See Audio System (page 124).
6. Allow the engine to idle for at least one minute. If the engine turns off,
step on the accelerator to start the
engine.
7. While the engine is running, step on the brake pedal and shift the
transmission to N.
8. Allow the engine to run for at least one minute by pressing on the
accelerator pedal.
9. Drive the vehicle at least 10 miles (16 kilometers) to completely
relearn the idle 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 trim strategy.
Note: Always dispose of automotive
batteries in a responsible manner.
Follow your local authorized standards
for disposal. Call your local authorized
recycling center to find out more about
recycling automotive batteries.
