charging CHEVROLET MONTE CARLO 2004 Owners Manual

Voltmeter Gage
If your vehicle is equipped
with the 3800 V6 engine it
has a voltmeter gage
that indicates battery
voltage.
If the gage reads less than 12 volts or more than
16 volts while the engine is running, and it stays there,
you may have a problem with the electrical charging
system.
Also, when your gage reads less than 11 volts or more
than 16 volts, your battery life indicator will be
illuminated in the message center. For more information
seeBattery Warning Message on page 3-45.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part isn’t working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on, there is a brake problem.
The LOW BRAKE FLUID message in the message
center will also appear when there is a brake problem.
SeeLow Brake Fluid Warning Message on page 3-50.
Have your brake system inspected right away.

this message will be
displayed for three
seconds.
If the message is displayed when the engine is running,

If there is a problem with the charging system, four
chimes will sound when the message comes on.
The battery display will also stay on while the key is in
ON until the engine is started.
If the message stays on after starting the engine it could
indicate a problem with the generator drive belt, or
some other charging system problem. Have it checked
right away. Driving with this message on could drain
your battery.
If you must drive a short distance with this message
displayed, it helps to turn off all your accessories.
