E/M sw&h (ELECTRONIC CLUSTER)
To change your electronic display from
English to metric units, or from metric
co English, press this switch down. The
gages affected are:
Speedometer
Odometer
Trip Odometer
Oil Pressure
Engine Coolant Temperature
mn-irrnrIII
The tachometer displays the engine
speed in revolutions per minute (rpm)
.
NOTICE:
Do not operate the engine with the
tachometer in the red area, or
engine
damage may occur.
4"' UNLEADED FUEL ONLY c
he/ Gage (STANDARD CLUSTER)
Your fuel gage tells you about how
much fuel you have left, when the
ignition is on. When the indicator nears
E (Empty), you will have a little fuel left
but should get more soon.
Here are four things that some owners
ask about. None of these show a
problem with your fuel gage:
At the service station, the gas pump
shuts off before the gage reads
F (Full) .

VOLTS
Voltmeter (STANDARD CLUSTER)
Your charging system gage will show
the rate of charge when the engine is
running. When the engine is not
running but the ignition is on (in the
Run position), the display measures thc
voltage output of your battery.
The reading will change as the rate
of
charge changes (with engine speed,
etc.), but readings between the warning
zones indicate the normal operating
range. Readings in either warning zone
indicate a possible problem with your
charging system. Have your Oldsmobilc
serviced immediately.

Engine Coolant Temperature
Gage
(STANDARD CLUSTER)
This gage shows the engine coolant
temperature. If the gage pointer moves
into the red area, your engine is too
hot!
It means that your engine coolant
has overheated.
If 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.
HOT COOLANT CAN BURN
YOU
BADLY!
In
Problems on the Road, this manual
shows what to do. See the
Index under

Fuel Gage (ELECTRONIC CLUSTER)
Your fuel gage bars light up when the
ignition is on
to show you about how
much fuel you have left.
When the gage first indicates empty,
you still have
a little fuel left, but you
should get more soon.
A box around the gas pump symbol wil:
flash when your tank is
1/8 full or less.
Here are five things that some owners
ask about. None of these show
a
problem with your fuel gage:
At the service station, the gas pump
shuts
off before the gage reads full.
The top bar does not go out until you
have driven a long distance-about
3r
miles (48 kilometers).

Fuel
Use regular unleaded gasoline rated at
87 octane or higher. Use premium
unleaded gasoline rated at 91 octane or
higher for high power performance,
when towing a trailer or with a high
payload requirement. But when
operating with a light load as
a normal
condition, you may use middle grade or
regular unleaded gasolines.
The gasoline you use should meet
specifications ASTM D4814 in the U.S.
and CGSB
3.5-92 in Canada. These
fuels should have the proper additives,
so you should not have to add anything
to the fuel.
In the
U.S. and Canada, it’s easy to be
sure you get the right kind of gasoline
(unleaded). You’ll see “UNLEADED” right
on the pump. And only unleaded
nozzles will fit into your vehicle’s filler
neck.
Be sure the posted octane is at least 91
for premium, 89 for middle grade and
87 for regular.
If the octane is less than
87, you may get a heavy knocking noise
when you drive. If it’s bad enough, it
can damage your engine.
If you’re using fuel rated at 91 octane or
higher and you still hear heavy
knocking, your engine needs service.
But don’t worry
if you hear a little
pinging noise when you’re accelerating
or driving up a hill. That’s normal, and
you don’t have to buy a higher octane
fuel to get rid of it. It’s the heavy,
constant knock that means you have a
problem.
What about gasoline with blending
materials that contain oxygen
(oxygenates), such as MTBE or
alcohol?
MTBE is “methyl tertiary-butyl ether.”
Fuel that
is no more than 15% MTBE is
fine for your vehicle.
Ethanol is ethyl or grain alcohol.
Properly-blended fuel that is no more than
10% ethanol is
fine for your
vehicle.
Methanol is methyl or wood alcohol.
NOTICE:
Fuel that is more than 5%
methanol is bad for your vehicle.
Don’t use it. It can corrode metal
parts in your fuel system and also
damage plastic and rubber parts.
That damage wouldn’t be covered
under your warranty. And even at
5% or less, there must be
“cosolvents” and corrosion
preventers in this fuel to help avoid
these problems.
GasoUnes for Cleaner Air
Your use of gasoline with deposit
control additives will help prevent
deposits from forming in your engine
and fuel system. That helps keep your
engine in tune and your emission
control system working properly. It’s
good for your vehicle, and you’ll be
doing your part for cleaner air.
Many gasolines are now blended with
oxygenates. General Motors
