Charging System Light; Brake System Warning Light - Pontiac 2006 G6 Owner's Manual

Charging System Light

If it stays on, or comes on while you are driving and you
hear a chime, you may have a problem with the
electrical charging system. It could indicate that you
have a loose generator drive belt or another electrical
problem. Have it checked right away. 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 for a few
seconds when you turn on
the ignition 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 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.
Have your brake system inspected right away.

This light should come on briefly when you turn the

fixed so it will be ready to warn you if there's a problem.
