Cadillac 2005 DeVille - Manual (Page 177)

BATTERY VOLTAGE LOW – 6: This message will
appear when the electrical system is charging less than
10 volts or if the battery has been drained. If this
message appears immediately after starting, 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 by your GM dealer 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.
You can monitor battery voltage on the DIC by
pressing the INFO button. The normal range is
11.5 to 15.5 volts.
CHANGE ENGINE OIL – 82: This means that the life
of the engine oil has expired. See Scheduled
Maintenance on page 6-4. After an oil change, the oil
life indicator must be reset. See Engine Oil Life System
on page 5-17. See Engine Oil on page 5-14 and Oil
Life Indicator on page 3-79 for more information.
CHANGE TRANS FLUID – 47: This message will
appear when it is time to change the transaxle fluid. See
Scheduled Maintenance on page 6-4 for the proper
fluid and change intervals.
After the transaxle fluid has been changed, the transaxle
fluid change indicator must be reset. See “How to
Reset the Transaxle Fluid Indicator” under Automatic
Transaxle Fluid on page 5-21.
CHECK BRAKE FLUID – 37: This message will
display if the ignition is in ON to inform the driver that
the brake fluid level is low. Have the brake system
serviced by your GM dealer as soon as possible. See
Brake System Warning and Parking Brake Indicator
Light on page 3-47.
CHECK COOLANT LEVEL – 2: This message will
appear when there is a low level of engine coolant. Have
the cooling system serviced by your GM dealer as
soon as possible. See Engine Coolant on page 5-24.
