You may wonder what happens if a car has to have a new odometer
installed. The new one will read the correct mileage. This is because the
computer stores the mileage in memory.
WMING LIGHTS
This section describes the warning lights that are on your vehicle. The
pictures will help you locate them.
Warning lights can signal that something is wrong before it becomes
serious enough to cause an expensive repair or replacement. Paying
attention to your warning lights 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.
When one
of the warning lights comes on and stays on when you are
driving, 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. They’re a big help.
Your vehicle may also have a driver information system that works along
with the warning lights. See “Driver Information System” in the Index.
Brake System Warning Light
Your Cadillac’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.
r
L-l
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.

Downloaded from www.Manualslib.com manuals search engine If the warning light comes on, there could be a brake problem. Have your
brake system inspected right away.
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 Cadillac” in the Index.)
A CAUTIEON
Your brake system may not be working properly if the brake
system warning li’ght 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.
The brake system warning light will also come on when you set your
parking brake, and it
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
ANTI-
LOCK (@)
With anti-lock,this
light will come on
when you start your
engine and may stay
on for several
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.

Downloaded from www.Manualslib.com manuals search engine If the light stays on, turn the ignition off. Or, if the light comes on when
you’re driving, stop as
soon as possible and turn the ignition off. Then
start the engine again to reset the system. If the light still stays on, or
comes
on again while you’re driving, your Cadillac 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 may also come on when you are
driving with a compact spare tire. If this happens, the light means you
won’t have anti-lock until you replace the compact spare with a full-size
tire.
If the warning light stays on after you replace the compact spare with
a full-size tire, or if it comes on again when you’re driving, your Cadillac
needs service.
Engine Temperature Warning Light (Canadian Only)
This light tells you that
your engine has
overheated. You should
stop the car and idle the
engine as soon as
possible. A warning
chime should also sound
if this light comes on. As
a check, the light should
come on for a few
seconds when
you start
your engine.
HOT COOLANT CAN BURN YOU BADLY!
In “Problems on the Road,” this manual shows what to do. See “Engine
Overheating” in the Index.

This light tells you if
there could be a
problem
with your
engine oil pressure.
The light goes
on when you turn your key to “Run” or “Start.” It goes off
once you start your engine. That’s just a check to be sure the light works.
If it doesn’t, be sure to have it fixed so it will be there to warn you if
something goes wrong.
When the light comes on and stays on, it means oil isn’t going through
your engine properly. You could be low on oil,
or you might have some
other oil problem.

control systems. This light should come on when the ignition is on, but
the engine is not running,

When you turn the key
to “Run” or “START”,
this light will come on
briefly,
to show that
your alternator and
battery charging
systems are working.
If a light stays on, you need service, and you should take your Cadillac to
the dealer at once. To save your battery until you get there, turn off all
accessories.
Fuel Gage
Your fuel gage shows about how much fuel is in your tank. It works only
when the ignition is in the
“RUN” position.
Digital Gage’
If the fuel level is within approximately one gallon (3.9 liters) of being full
the letter “F” is shown.

Downloaded from www.Manualslib.com manuals search engine If the fuel level is between 1 and 2 gallons (3.9 and 7.6 liters) from being
empty the letter
“E” is shown. If the fuel supply gets down to
approximately
1. gallon (3.9 liter) the “E” will flash, and the “ FUEL
LEVEL VERY LOW” message will appear in the Driver Information
Center (DIC).
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-
@ At the gas station, the gas pump shuts off before the gage reads “F”.
It takes more (or less) gas to fill up than the gage said. For example,
the gage said
“8 Gallons”, but it took more -- or less -- than the tank’s
remaining capacity to
fill it.
The gage may change when you turn, stop, or speed up is normal.
Fuel Data Panel
Your Fuel Data Panel tells you all you want to know about your fuel
economy and
how far you can travel with the fuel remaining. Here’s how
it works.
AVG Button Push this button to display the “AVG MPG” (average mile
per gallon).
You can also display it in metric units by pressing the “ENG
MET” button.

Downloaded from www.Manualslib.com manuals search engine When “AVG MPG” (average mile per gallon) is selected, the total
- distance is divided by the total fuel used.
INST Button When “INST MPG”(1nstantaneous Fuel Economy) is
selected, you will see what your fuel economy is at that instant. The
computer takes
a new reading twice every second. It will show economy
up to
70 miles per gallon (or 2 liters per 100 Kilometers).
AVG MPG Reset Press the INFORMATION button until the AVG MPG
is displayed on the Driver Information Center. Press and hold the
RESET button until both the Fuel Data Center and Driver Information
Center display reads
0.0 Another method to reset the AVG MPG is to
press the AVG button on the Fuel Data Panel.

RANGE Display This display shows how far the computer thinks you can
go with the fuel that is in your tank. The computer does not know what
driving conditions will be like for the rest
of your trip, so the range is
estimated based on your recent fuel economy. Therefore, your range
reading may change
as your driving habits change (going from city to
If the range display shows “Lo”, you should stop for fuel as soon as
possible.
Your computer needs enough data for the “RANGE” reading to work. It
will read
“Lo” for a while when your vehicle is brand new (under 25
miles). Also, it may show “Lo” for a while if your battery has been
disconnected.
