Charging System Light; Brake System Warning Light - Buick 2005 Century Owner's Manual

Charging System Light

If it stays on, or comes on while the vehicle is being
driven, there may be a problem with the charging
system. It could indicate that the vehicle has a loose
accessory belt or another electrical problem. Have
it checked right away. Driving while this light is on could
drain the battery.
If the vehicle must be driven a short distance with the
light on, be certain to turn off all the accessories,
such as the radio and air conditioner.

The charging system light
will come on briefly when
the ignition is turned on,
as a check to show that it
is working. Then it should
go out.

Brake System Warning Light

The vehicle's hydraulic brake system is divided into two
parts. If one part is not working, the other part can
still work and stop the vehicle. For good braking, though,
you need both parts working well.
If the warning light comes on, there is a brake problem.
Have the brake system inspected right away.

This light should come on briefly when the ignition

have it fixed so it will be ready to warn you if there
is a problem.
