Charging System Light; Brake System Warning Light - Buick 2010 Lucerne Owner's Manual

Charging System Light

If it does not, have the vehicle serviced by your
dealer/retailer.
The light should go out once the engine starts. If it stays
on, or comes on while driving, there could be a
problem with the charging system. A charging system
message in the Driver Information Center (DIC) can also
appear. See DIC Warnings and Messages on page 4-55
for more information. This light could indicate that
there are problems with a generator drive belt, or that
there is an electrical problem. Have it checked right
away. If the vehicle must be driven a short distance with
the light on, turn off accessories, such as the radio
and air conditioner.

This light comes on briefly
when the ignition key is
turned to START, but
the engine is not running,
as a check to show it
is working.

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 both
parts need to be working.
If the warning light comes on, there is a brake problem.
Have the brake system inspected right away.
United States

will be ready to warn if there is a problem.
