Charging System Light
This red light will come on
briefly when you turn on the
ignition, but the engine is
not running, as a check to
show you it is working.
Then it should go out when
the engine starts.
Brake System Warning Light
BRAKE
Your Geo'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 it stays on, or comes on while you are driving, 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 charging
system light on, be certain to turn off all your
accessories, such as the radio and air conditioner.
If the warning light comes on, there could be a brake
problem. Have your brake system inspected right away.
This light should come on briefly as you start the
vehicle. If it doesn't come on then, have it fixed so it
will be ready to warn you if there's a problem.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the floor.
It may take longer to stop. If the light is still on, or if the
anti-lock brake system warning light is flashing, have
the vehicle towed for service. (See "Anti-Lock Brake
