Warning Lights, Gages and
Indicators
This section describes the warning lights
and gages that may be on your vehicle.
The pictures will help you locate them.
Warning lights and gages can signal that
something is wrong before it becomes
serious enough to cause an expensive
repair or replacement. Paying attention
to your warning lights and gages could
also save you or others from injury.
Warning lights go on when there may
be or is a problem with one of your vehicle’s
functions.
As you will see in
the details on the next few pages, some
warning lights come on briefly when
you turn the ignition key just to let you
know they’re working.
If you are
familiar with this section, you should
not be alarmed when this happens.
Gages can indicate when there may be
or is a problem with one of your
vehicle’s functions. Often gages and
warning lights work together to let you
know when there’s a problem with your
vehicle. When
one of the warning lights comes
on and stays on when you are driving,
or when one of the gages shows there
may be a problem, check the section
that tells you what to do about it. Please
follow the manual’s advice. Waiting to
do repairs can be costly-and even
dangerous.
So please get to know your
warning lights and gages. They’re a big
help.

with the ignition on, you may have a
problem with the fuse or bulb. Have it

at a stop, the light may blink on and
off. This is normal.
If you make a hard stop, the light may
come on for a moment. This is

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 ipition is on (in the
Run position),
the gage shows your battery‘s state
of
charge.

two parts. If one I

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 Towing
Your Oldsrnobile.)
CAUTION
Your brake system may not I

brake warning light is on. Driving
with the brake warning light on can
lead to an accident. If the light is
still on after you’ve pulled
off the
road and stopped carefully, have
the vehicle towed for service.
Anti-Lock Brake System Warning
Light
(opTloN)
With anti-lock, this light will go on
when you start your engine and it will
stay on for three seconds. That’s
normal. If the light doesn’t come on,
have it fixed
so it will be ready to warn
you if there is a problem.
If the light stays on or comes on when
you’re driving, stop as soon as possible
and turn the key
off. Then start the
engine to reset the system.
If the light
still stays on, or comes
on again while
you’re driving, your Oldsmobile needs
service. Unless the regular brake system
warning light
is also on, you will still
have brakes, but not anti-lock brakes.
If

light ever flashes, your anti-lock bralre system is still working but needs service
as soon as possible.

fuel, ignition and emission control
.systems.
This light should come on
when the ignition is on, but the engine
is not running, as a check
to show you-

all, have it fixed right away. If it stays
on,
or it comes on while you are driving,
the computer is indicating that you
