When a low voltage battery replacement is
necessary, see an authorized dealer to
replace the low voltage battery with a Ford
recommended replacement low voltage
battery that matches the electrical
requirements of the vehicle
To ensure proper operation of the battery
management system (BMS), do not allow a
technician to connect any electrical device
ground connection directly to the low voltage
battery negative post. A connection at the
low voltage battery negative post can cause
inaccurate measurements of the battery
condition and potential incorrect system
operation.
Note:
If a person adds electrical or electronic
accessories or components to the vehicle,
the accessories or components may
adversely affect the low voltage battery
performance and durability and 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. Also, make
certain the battery cables are always tightly
fastened to the battery terminals. 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. Note:
Until you switch the ignition to the on
position, you will receive a message in your
information display stating that your vehicle
is not in park.
Complete the following procedure in order
to restore the settings:
1. With the vehicle at a complete stop, 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 370). Reset the power windows
bounce-back feature. See Windows and
Mirrors (page 93). Reset the radio station
presets.
See Audio System (page 370).
6. Allow the engine to idle for at least one minute. If the engine turns off, step on
the accelerator to start the engine.
