Cadillac 2008 CTS - Manual (Page 194)

Battery Volts Low
This message displays when 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 to boost the battery after returning
home or to a final destination. Make sure you follow
the manufacturer’s instructions.
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 vehicle information button until Battery Voltage is
displayed.

Drive the vehicle in circles at less than 5 mph (8 km/h) to

complete. See DIC Compass on page 3-52 for more

Change Engine Oil Soon
When this message displays, it means that service is
required for your vehicle. See your dealer/retailer.

by clearing it from the display, you still must reset
