Maintenance 321 Battery Management System (If Equipped) The battery management system (BMS) monitors battery conditions and takes actions to extend battery life. If excessive battery drain is detected, the system may temporarily disable certain electrical features to protect the battery. Those electrical accessories affected include the rear defrost, heated/cooled seats, climate control fan, heated steering wheel, audio and navigation system. A message may be shown in the information displays to alert the driver that battery protection actions are active. These messages are only for notification that an action is taking place, and not intended to indicate an electrical problem 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 which matches the electrical requirements of the vehicle. After battery replacement, or in some cases after charging the battery with the 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 the 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. 2013 F-250/350/450/550 (f23) Owners Guide gf, 3rd Printing, December 2012 USA (fus)

Battery Management System (If Equipped)
The battery management system (BMS) monitors battery conditions
and takes actions to extend battery life. If excessive battery drain is
detected, the system may temporarily disable certain electrical features
to protect the battery. Those electrical accessories affected include the
rear defrost, heated/cooled seats, climate control fan, heated steering
wheel, audio and navigation system. A message may be shown in the
information displays to alert the driver that battery protection actions
are active. These messages are only for notification that an action is
taking place, and not intended to indicate an electrical problem 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 which matches
the electrical requirements of the vehicle. After battery replacement,
or in some cases after charging the battery with the 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 the
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.
