that monitors the charging status of
the 12 V auxiliary battery.
If the auxiliary battery level is low, the
main high voltage battery charges
the auxiliary battery.

The Aux. Battery Saver+ function will
be ON when the vehicle is delivered. If
the function is not needed, you may
turn it off in the Users Settings mode
on the cluster. For more information,
refer to the following page.

When the vehicle is OFF with all
doors, hood and liftgate closed, the
Aux. Battery Saver+ activates
according to the auxiliary battery
status.

When the Engine Start/Stop button
is in the ON position with the charg-
ing connector plugged in, the func-
tion activates according to the auxil-
iary battery status to prevent
overdischarge of the auxiliary bat-
tery.Information

Battery Saver+ function activates
more than 10 times consecutively
when in the automatic mode, the
function will stop activating, judg-
ing that there is a problem with the
auxiliary battery. In this case, drive
the vehicle for some period of time

vating.
