Voltmeter
(OPTION)
When the engine is running, the gage
shows the condition of the charging
system. Readings between the red
warning zones indicate the normal
operating range.
Readings in either red warning zone
indicate a possible problem in the
electrical system. Have your vehicle
serviced immediately.
When your engine is not running, but
the ignition is on (in the Run position),
the gage shows your battery's state of
charge.
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
work and stop you. For good bralung,
though, you need both parts working
well. If the warning light goes on, there
could be a brake problem.
Have your brake system inspected right
away.
This light should come on 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.
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.
If the light comes on while driving, pull
off the road and stop carefully. You maJ
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, have the vehicle towed for
service. (See the Index under Towing
Your Pontiac.)
