CHARGING THE 12V BATTERY

Battery Management System
The battery management system 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.

Maintenance
Electrical accessory installation
To ensure proper operation of the Battery
Management System, any electrical
devices that are added to your vehicle
should not have their ground connection
made directly at the negative battery post.
A connection at the negative battery
terminal can cause inaccurate
measurements of the battery condition
and potential incorrect system operation.
When a battery replacement is required,
you must use a recommended
replacement battery that matches the
electrical requirements of the vehicle.
After battery replacement, or in some
cases after charging the battery with the
external charger, the Battery Management
System 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
Battery Management System may disable
electrical features (to protect the battery)
earlier than normal.

CHANGING THE 12V BATTERY

For vehicles with start-stop the
battery requirement is different. You
must replace the battery with one of
exactly the same specification.
