Voltmeter (OPTION)
When the engine is running, the gage
shows the condition

system. Readings between the red
warning zones indicate the normal

serviced immediately.

Brake System Warning Light
Your Pontiac’s hydraulic brake system
is divided into two parts. If one part
isn’t working, the other part can still

though, you need both parts working
well.
If the warning light goes on, there
could be a brake problem.

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.
This light will also come on when you
set your
parking brake, and will stay on
if your parking brake doesn’t release fully.
If it stays on after your parking
brake is fully released, it means you
have a brake problem.
