Operation of Lights
Although your vehicle’s lighting system (headlights, parking lights, fog
lamps, side marker lights and taillights) meet all applicable federal
lighting requirements, certain states and provinces may apply their own
lighting regulations that may require special attention before you operate
-
these lights.
For example, some jurisdictions may require that you operate your. lower
beam lights with fog lamps at all times, or that headlights be turned on
whenever you must use your windshield wipers.
In addition, most
jurisdictions prohibit driving solely with parking lights, especially at dawn
or dusk. It is recommended that you check with your own state
or
provincial highway authority for applicable lighting regulations.

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.

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.

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.
