When the battery is disconnected or a new battery installed, the
transmission must relearn its adaptive strategy. As a result of this, the
transmission may shift firmly. This operation is considered normal and
will not affect function or durability of the transmission. Over time the
adaptive learning process will fully update transmission operation to its
optimum shift feel.
If the battery has been disconnected or a new battery has been installed,
the clock and the preset radio stations must be reset once the battery is
reconnected.
•Always dispose of automotive
batteries in a responsible manner.
Follow your local authorized
standards for disposal. Call your
local authorized recycling center
to find out more about recycling
automotive batteries.
Battery management system
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 rear
defrost, heated /cooled seats, climate control fan, heated steering wheel,
audio and navigation system. A message may be displayed on the
instrument cluster or center stack display to alert the driver that battery
protection actions are active. See theMessage centerin theInstrument
ClusterandEntertainment systemschapters 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.
