Features & Controls
Voltmeter
(omoN)
When your engine is running, this gage
shows the condition of your charging
system.
When your engine is not running, but
the ignition is on (in the Run position),
the gage shows your battery's state of
charge in DC volts. 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.
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 braking, 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 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,
have the vehicle towed for service. (See
the Index under Bwing Your Pontiac.)
