cluster or center stack display to alert the driver that battery protection
actions are active. See the Information displays in the Instrument
Cluster and Entertainment systems chapters for more information.
These messages are only for notification that an action is taking place,
and do not necessarily indicate that an electrical problem exists or that
the battery requires replacement.
Electrical accessory installation
To ensure proper operation of the BMS, any electrical devices that are
added to the vehicle should not have their ground connection made
directly at the negative battery post. A connection at the negative battery
post can cause inaccurate measurements of the battery condition and
potential incorrect system operation.
Note: Electrical or electronic accessories added to the vehicle by the
dealer or the owner may adversely affect battery performance and
durability and may also affect the performance of other electrical systems
in the vehicle.
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. After battery replacement, or
in some cases after charging the battery with an external charger, the
BMS requires eight hours of vehicle sleep time (key off with doors
closed) to relearn the new battery state of charge. Prior to relearning
state of charge, the BMS may disable electrical features (to protect the
battery) earlier than normal.

CHECKING THE WIPER BLADES

Run the tip of your fingers over the edge of the blade
to check for roughness.
Clean the wiper blades with washer fluid or water
applied with a soft sponge or cloth.
