Voltmeter Gage
(J VOLTS
When your engine is not
running, but
the ignition is
on
(in the RUN position),
this gage shows your
battery's state of charge
in
DC volts.
When
the engine is running, the gage shows the
condition of the charging system. Readings between the
low and high warning zones indicate the normal
operating range. Readings
in the low warning zone may occur when a
large number
of electrical accessories are operating in
the vehicle and the engine is left at an idle for an
extended period. This condition is normal since the
charging system is not able
to provide full power at
engine idle.
As engine speeds are increased, this
condition should correct itself as higher engine speeds
allow the charging system to create maximum power.
You can only drive for a short time with the reading in
either warning zone. If you must drive, turn off all
unnecessary accessories.
Readings in either warning zone indicate a possible
problem
in the electrical system. Have the vehicle
serviced as soon
as possible.

Brake System Warning Light
Your Oldsmobile’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 comes on, there could be a brake
problem. Have your brake system inspected right away.
BRAKE
This light should come on
briefly when you
turn the
ignition key to
RUN. 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, have the
vehicle towed for service. (See “Towing Your Vehicle”
in the Index.)
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system 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.
When the ignition is on, the brake system warning light
will also come on when you set your parking brake. The
light 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.

Anti-Lock Brake System Warning Light
With the anti-lock brake
system, this light will come
on when you start your
engine and may stay on
for several seconds.
That‘s normal.
Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature.
If the
gage pointer moves into the
red area, your engine is
too hot!
If the light stays on, or comes on when you’re driving,
your Oldsmobile needs service. If the regular brake
system warning light isn’t
on, you still have brakes, but
you don’t have anti-lock brakes.
If the regular brake
system warning light is also on, you don’t have anti-lock
brakes and there’s a problem with your regular brakes.
See “Brake System Warning Light” earlier in this part.
The anti-lock brake system warning light should come
on briefly when you turn
the ignition key to RUN. If the
light doesn’t come on then, have
it fixed so it will be
ready
to warn you if there is a problem. It
means that your engine coolant has overheated.
Tf you
have been operating your vehicle under normal driving
conditions, you should pull off the road, stop your
vehicle and turn off the engine
as soon as possible.
In “Problems on the Road,”
this manual shows you what
to do. See “Engine Overheating” in the Index.

Malfunction Indicator Lamp (Service Engine
Soon Light)
SERVICE
ENGINE
SOON
Your Oldsmobile is
equipped with a computer
which monitors operation of
the fuel, ignition and
emission control systems.
This system is called OBD
I1 (On-Board
Diagnostics-Second Generation) and is intended
to assure that emissions are at acceptable levels for
the life
of the vehicle, helping to produce a cleaner
environment. The SERVICE ENGINE
SOON light
comes on to indicate that there is a problem and service
is required. Malfunctions often will be indicated by the
system before any problem is apparent, which may
prevent more serious damage to your vehicle. This
system is also designed to assist your service technician
in correctly diagnosing any malfunction.

NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running.
If the light doesn’t come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:
Light Flashing -- A misfire condition has been
detected. A misfire increases vehicle emissions and
may damage the emission control system on your
0
vehicle. Retailer or qualified service center diagnosis
and service is required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Retailer
or qualified service center diagnosis and
service may be required.

off and the parking brake
is released.
Check Gages Light
CHECK
GAGES
The CHECK GAGES light
will come on briefly when
you are starting the engine.
If the light comes on and
stays on while you are
driving, check your coolant
temperature and engine oil
pressure gages
to see if they
are in the warning zones.

Fuel Gage
When the ignition is on,
the fuel gage tells you
about how much
fuel you
have remaining. Here are four things that some owners
ask about. None
of these show a problem with your fuel gage:
0 At the gas station, the gas pump shuts off before the
gage reads
FULL (F).
It takes a little more or less fuel to fill up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but
it actually took a
little more or less than half the tank’s capacity to fill
the tank.
The gage moves a little when you turn a corner or
speed up.
The gage doesn’t go back to EMPTY (E) when you
turn off the ignition.

Rear Window Defogger
I
The rear window has lines that warm the glass. For best
results, clear the window of
as much snow or ice as
possible before using the rear window defogger.
To turn on the rear window defogger, find the switch
marked
REAR DEFOG on your instrument panel below
the headlamp switch. Press
ON until the light in the
switch comes on, then release
it. It will only work if the
ignition switch is turned
to RUN.
The rear window defogger will stay on for five to
seven minutes, then turn off. If you need additional
warming time, turn it
on again. You can turn the
defogger off at any time by pressing
OFF.
Do not attach a temporary vehicle license, tape or decals
across the defogger grid
on the rear window.
NOTICE:
Don’t use a razor blade or something else sharp
on the inside
of the rear window. If you do, you
could cut
or damage the warming grid, and the
repairs wouldn’t be covered by your warranty.
