FUEL GAGE
fI
I
Your fuel gage shows
about how much fuel is
in your tank.
It works only when the ignition is in the “RUN” position. The
17 bar
segments show the fuel remaining in your tank.
When only one bar segment still is lit, the
“LOW FUEC’ light will go on.
If the fuel supply gets critically low, none of the bar segments will be lit
and the
“LOW FUEC’ will flash. You should get fuel immediately.
Here are
a few concerns some owners have had about the fuel gage. All
these situations are normal and indicate nothing wrong with the fuel
gage.
The pump at the gas station shuts off before the fuel gage reads “F”.

It takes more (or less) gas to fill up than the gage said. For example,
the gage said
“l/Y, but it took more or less than half the tank capacity -
to fill it. I
The gage changes when you turn (or stop,or speed up)
OIL LIFE INDICATOR
Your Cadillac has an Oil Life Indicator feature. This tells you when you
need to change your engine
oil. It’s based upon the engine oil
temperatures and your driving patterns.

The “CHANGE OIE’ light will come on for a few seconds as a bulb check
when
you start your engine. The system probably will say to change the oil
-.

You can be injured if you try to do service work on a vehicle
without knowing enough about it.
0 Be sure you have sufficient knowledge, experience, and the
proper replacement parts and tools before you attempt any
vehicle maintenance task.
0 Be sure to use the proper nuts, bolts and other fasteners.
“English” and “metric” fasteners can be easily confused.
If
you use the wrong fasteners, parts can later break or fall off.
You could be hurt.

FUEL
Use regular unleaded gasoline rated at 87 octane or higher. It 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.
1 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
87. 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
87 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,

A CAUTION:
Gasoline vapor is highly flammable. It burns violently, and that
can cause very bad injuries. Don’t smoke if you’re near gasoline
or if you’re refueling your vehicle. Keep sparks, flames, and
I
smoking materials away from gasoline.
c_ If you’re refueling your tank using a hydrocarbon recovery nozzle, the
fuel pump may shut off before the fuel capacity of your tank reaches full.
This is a normal condition. If you slow the
flow of fuel going into the
tank, it is more likely to fill to capacity without shutting off.
__
Locking Fuel Filler Door (Option)
m Your vehicle may have the locking fuel filler door.
The cap is behind the license plate. Pull down from the top of the license
plate bracket door to open.
