Then it should go out when the engine is started.
If it stays on, or comes on while you are driving, you
may have a problem with the electrical charging system.
Have it checked by your GM dealer. Driving while this
light is on could drain your battery.
If you must drive a short distance with the light on, be
certain to turn off all your accessories, such as the radio
and air conditioner.

The charging system light
will come on briefly when
you turn on the ignition,
and the engine is not
running, as a check
to show you it is working.

Brake System Warning Light

Your vehicle's hydraulic brake system is divided into
two parts. If one part is not 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.
Have your brake system inspected right away.
When the ignition is on, the brake system warning light
will also come on when you set your parking brake.
The light will stay on if your parking brake does not fully
release. If it stays on after your parking brake is fully
released, it means you have a brake problem.
This light should come on
briefly when you turn the
ignition to ON. If it does not
come on then, have it
fixed so it will be ready to
warn you if there is a
problem.
