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 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.

Damage to your engine from neglected oil problems can De
costly

Downloaded from www.Manualslib.com manuals search engine The system probably will say to change the oil between 3000 miles
(5000 km) and 7500 miles (12500 km), but it may even say to change it
before
3000 under very severe conditions. It all depends on your driving
patterns. If it’s been
7500 miles (12500 km) it always says to change the oil.
There are
two things the system doesn’t do:
0 It can’t sense heavy dust in the places where you drive. If you drive in
a dusty area, you should change your oil every
3000 miles (5000 km)
or
3 months (whichever comes first), unless the display says to change
it even sooner than that.
It doesn’t check how much oil you have, so you’ll still have to check
for that.
To see how, see Engine Oil in the Index.
men You’ve Changed the Oil
When new oil is put in, you’ll need to reset your system. To do it, display
the “OIL LIFE INDEX” by pressing the INFORMATION button. Then
press and hold the RESET buttons until the display shows
“100 OIL
LIFE LEFT”
Electronic Level Control
This keeps your car level.
The ignition has to be “ON” for the level control to work. When you turn
the ignition off, you may hear the level control exhausting. The system
consists
of an electronic height sensor, a small electric air compressor,
and air adjustable shock absorbers mounted on the rear
of the vehicle.
If the system has a slight leak, the air compressor will run frequently for a
few seconds each time.
For
a massive air leak, the air compressor will stay on for approximately
7 minutes. You should see your dealer for service, but you can keep
driving your Cadillac.
