Downloaded from www.Manualslib.com manuals search engine I /11 CAUTION:
I
Both frontal and side impact air bags inflate with
great force, faster than the blink
of an eye. If
you’re too close to an inflating air bag, it could
seriously injure you. Safety belts help keep you in
position for air bag inflation before and during
a
crash. Always wear your safety belt, even with air
bags. The driver should sit as far back as possible
while still maintaining control of the vehicle.
Front occupants should not lean on or sleep
against the door.
I /i CAUTION:
An inflating air bag can seriously injure small
children. Always secure children properly in your
vehicle. To read how, see the part of this manual
called “Children” and the caution label on the
right front passenger’s safety belt.
AIR BAG
There is an air bag readiness light on the instrument
panel, which shows AIR BAG.
The system checks the
air bag electrical system for
malfunctions. The light tells you if there is an electrical
problem. See “Air Bag Readiness Light” in the Index
for more information.

Downloaded from www.Manualslib.com manuals search engine Safety Belt Extender
If the vehicle’s safety belt will fasten around you, you
should use it.
But
if a safety belt isn’t long enough to fasten, your
dealer will order you an extender. It’s free. When you go
in to order it, take the heaviest coat you will wear,
so the
extender will be long enough for you. The extender will
be just for you, and just for the seat in your vehicle that
you choose. Don’t let someone else use it, and use it
only for the seat it is made to fit.
To wear it, just attach it
to the regular safety belt.
Checking Your Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors and
anchorages are working properly.
Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from
doing its job, have
it repaired.
Tom
or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces. If a belt
is torn or frayed, get a new one right away.
Also look for any opened or broken air bag covers, and
have them repaired
or replaced. (The air bag system
does not need regular maintenance.)
Replacing Restraint System Parts
After
a Crash
If you’ve had a crash, do you need new belts?
After a very minor collision, nothing may be necessary.
But if the belts were stretched, as they would be
if worn
during a more severe crash, then you need new belts.
If belts are cut or damaged, replace them. Collision
damage also may mean you will need to have safety belt
or seat parts repaired or replaced. New parts and repairs
may be necessary even if the belt wasn’t being used at
the time of the collision.
If an air bag inflates, you’ll need to replace air bag
system parts. See the part on the air bag system earlier
in this section.

the turn signal is left on, a warning chime will sound
and the
DIC will display TURN SIGNAL ON (after
driving about
a mile) to remind you to turn it off.
Arrows that flash rapidly when signaling for a turn or
lane change may be caused by a burned out signal bulb.
Other drivers won’t see the turn signal.

Downloaded from www.Manualslib.com manuals search engine Warning Lights, Gages and Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help
you
locate them.
Warning lights and gages can signal that something
is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
your warning lights and gages could also save
you or
others from injury.
Warning lights come 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 start the
engine just
to let you know they’re working. If you are
familiar with this section, you should not be alarmed
when this happens.
Gages can indicate when there may be
or is a problem
with one of your vehicle’s functions. Often gages and
warning lights work together to let you know when
there’s
a problem with your vehicle.
When one of the warning lights comes
on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you what
to do about it. Please follow this manual’s advice.
Waiting to do repairs can be costly
-- and even
dangerous.
So please get to know your warning lights
and gages. They’re a big help.
Your vehicle also has a Driver Information Center that
works along with the warning lights and gages. See
“Driver Information Center” later in this section.
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for about eight seconds
to remind people to
fasten their safety belts, unless the driver’s safety belt
is
already buckled.
The safety belt light will
also come on and stay
on
for about 20 seconds,
then it will flash for about
70 seconds. If the driver’s
belt
is already buckled,
neither the chime nor the light will come on.

Downloaded from www.Manualslib.com manuals search engine Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR BAG. The system checks the
air bag’s electrical system
for malfunctions. The light
tells you
if there is an electrical problem. The system
check includes the air bag sensors, the air bag modules,
the wiring and the crash sensing and diagnostic module.
For more information on the air bag system, see “Air
Bag” in the Index.
AIR BAG
This light will come on
when you start your engine, and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready. The
air bag readiness light should flash for a
few
seconds when you turn the ignition key to RUN. If the
light doesn’t come on then, have it fixed
so it will be
ready to warn you if there
is a problem.
Charging System Indicator Light
When you turn the key to
RUN, this light will come
on briefly
to show that
the generator and battery charging systems
are working.
If this 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.
If the air bag readiness light stays on after you start the
engine or comes on when you
are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.

Warning
Light
This light tells you that your
engine has overheated. You
should stop the car and turn
the engine
off 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. In the section “Problems on
the Road,” this manual explains what to do. See “Engine
Overheating” in the Index.
Engine Coolant Temperature Gage
Analog Cluster
This gage shows the
engine coolant
temperature.
If the gage
pointer moves into the red
area, the engine is too hot.
That reading means the same thing as the warning
light
-- the engine coolant has overheated. The section
“Problems on the Road” in this manual explains what to
do. See “Engine Overheating” in the Index.

Downloaded from www.Manualslib.com manuals search engine Malfunction Indicator Lamp (Service Engine Soon Light)
SERVICE
ENGINE
SOON
Your Cadillac is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system
is called OBD I1 (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the life
of the vehicle, helping
to produce a cleaner
environment. (In Canada, OBD
I1 is replaced by
Enhanced Diagnostics.) The SERVICE
ENGINE SOON
light comes on and a chime will sound to indicate that
there is a problem and service is required. Malfunctions
often will be indicated by the system before any
problem is apparent. This may prevent more serious
damage to your vehicle. This system is also designed to
assist your service technician in correctly diagnosing
any malfunction.
I NOTICE:
~
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine
is not
running. If the light doesn’t come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:
0 Light Flashing -- A misfire condition has been
detected.
A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis and service is required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.

Downloaded from www.Manualslib.com manuals search engine If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
0 Reducing vehicle speed.
0 Avoiding hard accelerations.
0 Avoiding steep uphill grades.
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops flashing and remains on steady, see “If
the Light Is On Steady” following.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least
10 seconds and restart the
engine.
If the light remains on steady, see “If the Light
Is On Steady” following.
If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you just drive through
a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system dries
out.
A few driving trips should turn the
light off.
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently as designed since small amounts of
air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure to install the fuel cap properly. It
will take a few driving trips to turn the light off.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index).
Poor fuel quality will cause your
engine not to
run as efficiently as designed. You may
notice
this as stalling after start-up, stalling when you put
the vehicle into gear, misfiring, hesitation on acceleration
or stumbling on acceleration. (These conditions may go
away once the engine is warmed up.)
This will be detected
by the system and cause the light to
turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least one
full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.

8
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 a
check to be sure the light works. If it doesn’t come on,
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 that oil isn’t
flowing through your engine properly.
You could be low on
oil and you might
have some other system problem.
CAI JTTON:
Don’t keep driving if the oil ssure is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil
as soon as possible and have your
vehicle serviced.
hOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.
