BATTERY VOLTAGE LOW
When this message displays, the electrical system
is charging less than 10 volts or the battery has
been drained.
If this message appears immediately after starting the
engine, it is possible that the generator can still recharge
the battery. The battery should recharge while driving
but may take a few hours to do so. Consider using
an auxiliary charger (be sure to follow the
manufacturer's instructions) to boost the battery after
returning home or to a final destination.
If this message appears while driving or after starting
your vehicle and stays on, have it checked immediately
to determine the cause of this problem.
To help the generator recharge the battery quickly, you
can reduce the load on the electrical system by
turning off the accessories.
The normal battery voltage range is 11.5 to 15.5 volts.
You can monitor battery voltage on the DIC by pressing
the information button until you find BATTERY VOLTS.
