Ford TRANSIT 2022 Owner's Manual page 389

WARNING: This vehicle may have
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.
WARNING: For vehicles with
Auto-Start-Stop the battery requirement
is different. You must replace the battery
with one of exactly the same
specification.
WHAT IS THE BATTERY
MANAGEMENT SYSTEM
The battery management system monitors
battery conditions and takes actions to
extend battery life.
HOW DOES THE BATTERY
MANAGEMENT SYSTEM WORK
If excessive battery drain is detected, the
system temporarily disables some
electrical systems to protect the battery.

• Heated rear window.
• Heated seats.
• Climate control.
• Heated steering wheel.
• Audio unit.
• Navigation system.
A message could appear in the information

and not intended to indicate an electrical
problem or that the battery requires
replacement.

Maintenance
BATTERY MANAGEMENT SYSTEM
LIMITATIONS
After battery replacement, or in some
cases after charging the battery with an
external charger, the battery management
system requires eight hours of vehicle sleep
time to relearn the battery state of charge.
During this time, your vehicle must remain
fully locked with the ignition switched off.
Note: Prior to relearning the battery state
of charge, the battery management system
could temporarily disable some electrical
systems.
Electrical Accessory Installation
To make sure the battery management
system works correctly, do not connect an
electrical device ground connection
directly to the battery negative post. This
can cause inaccurate measurements of
the battery condition and potential
incorrect system operation.
Note: If you add electrical accessories or
components to the vehicle, it could
adversely affect battery performance and
durability. This could also affect the
performance of other electrical systems in
the vehicle.
CHANGING THE 12V BATTERY -
3.5L DURATEC/3.5L ECOBOOST
The battery is under the driver seat.
Note: If you have power seats and the
battery has no charge, jump-start your
vehicle to move the seat. See Jump
Starting the Vehicle (page 349).
