The battery sensor is deactivated,
when the battery is disconnected
from the negative pole for mainte-
nance purpose.
In this case, the ISG system is limit

edly operated due to the battery sen-
sor deactivation. Thus, the driver
needs to take the following proce-

after disconnecting the battery.

Keep the engine in the OFF status for
4 hours, and attempt to restart the
engine 3 to 4 times for the battery-
