A CAUTION:
Don’t let anyone ride where they cadt wear a safety beIt
properly. If you are in a crash and you’re not wearing a safety
belt, your injuries can be much worse, You can hit things inside
the vehicle or be ejected from it. You can be seriously injured or
killed. in the same crash, you might not be if you are buckled
up. Always fasten your safety belt, and check that your
passengers’ belts are fastened properly too.
This figure lights up when you turn the key to “Run” or “Start” when
your safety belt isn’t buckled, and you’ll hear a chime,
too. It’s the
reminder to buckle up.
In many states and Canadian provinces, the law
says to wear safety belts.
Here’s
why: They work.
You never know
if you’ll be in a crash. If you do have a crash, you don’t
know
if it will be a bad one.
A few crashes are very mild. In them, you won’t get hurt even if you’re
not buckled up. And some crashes can be
so serious, like being hit by a
train, that even buckled up a person wouldn’t survive.
But most crashes
are
in between. In many of them, people who buckle up can survive and
sometimes
walk away. Without belts they could be badly hurt or killed.
After
25 years of safety belts in vehicles, the facts are clear. In most
crashes buckling
up does matter ... a lot!

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

inflation in a crash. Always wear your safety belt, even with an
air bag, and the driver

still maintaining control of the vehicle.

when leaving your vehicle.
PASS-KEY 11 TM
Your vehicle is equipped with the PASS-Key I1 TM (Personalized
Automotive Security System) theft deterrent system. PASS-Key I1
TM is a
passive theft deterrent system. This means you don’t have to do anything
different to arm or disarm the system. It works when you insert or remove
the key from the ignition. PASS-Key
’“ uses a resistor pellet in the
ignition key that matches a decoder
in your vehicle.
When the PASS-Key
I1 TM system senses that someone is using the wrong
key,
it shuts down the vehicle’s starter and fuel systems. For about three
minutes, the starter won’t work and fuel
won’t go to the engine. If
someone tries
to start your vehicle again or uses another key during this
time, the vehicle
will not start. This discourages someone from randomly
trying different keys with different resistor pellets in an attempt
to make a
match.
The ignition
key must be clean and dry before it’s inserted in the ignition
or the engine may not start. If the “SECURITY” light comes
on, the key
may be dirty or wet.
If this happens and the starter won’t work, turn the ignition off. Clean
and
dry the key. Wait about three minutes and try again. The security
light
will remain on during this time. If the starter still won’t work, and

Downloaded from www.Manualslib.com manuals search engine the key appears to be clean and dry, wait about three minutes and try the
other ignition key. At this time, you may also want to check the fuse (see
“Fuses and Circuit Breakers”
in the Index). If the starter won’t work with
the other key, your vehic1.e needs service. If your vehicle does start, the
first ignition
key may be faulty. See your Cadillac dealer or a locksmith
who can service
the PASS-Key I1 TM .
However, if you accidentally use a key that has a damaged or missing
resistor pellet, the starter won’t work, the security light
will flash. But you
don’t have to wait three minutes before trying one of the ignition keys.
If the resistor pellet is damaged or missing, the starter won’t work. Use
the other ignition key, and
see your Cadillac dealer or a locksmith who
can service the Pass-Key
I1 TM to have a new key made.
If you’re ever driving and
the “SECURITY” light comes on and
continues to flash,
you get the PASS-KEY MALFUNCTION message ,
and the “STARTING DISABLED” message appears, you will be able to
restart your engine
if you turn it off. Your PASS-Key I1 TM system,
however, is not working properly and must be serviced bylour Cadillac
dealer. Your vehicle
is not protected by the PASS-Key I1 system.
If you lose or damage a PASS-Key I1
lM ignition key, see your Cadillac
dealer or a locksmith who can service PASS-Key I1
TM to have a new key
made.

As you signal a turn or a lane change, if the arrows don’t flash but just
stay
on, a signal bulb may be burned out and other drivers won’t see your
turn signal.
If a bulb is burned out, replace it to help avoid an accident. If the green
arrows don’t go on at all when you signal
a turn, check the fuse (see
“Fuses” in the Index) and for burned-out bulbs.

The control is next to the headlight switch. It switches your lights on and
off by sensing how dark it is outside. To operate it, leave the light switch
off and move the control to any position but off.
If you move the control all the way to MAX, your lights will remain on for
90 seconds after you turn your engine off. If you move the control almost
all the way in the other direction,
so it is just on, the lights will go off
quickly when you turn off your engine. You can change this delay time
from
only a few seconds to 90 seconds.
Operation of Lights
Although your vehicle’s lighting system (headlamps, parking lamps, fog
lamps, side marker lamps and tail lamps) 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 lamps. For example, some jurisdictions may require that you
operate your lower beam lamps with fog lamps at all times, or that
headlamps be turned on whenever you must use your windshield wipers.
In addition, most jurisdictions prohibit driving solely with parking lamps,
especially at dawn or dusk.
It is recommended that you check with your
own State or Provincial highway authority for applicable lighting
regulations.

You may wonder what happens if a car has to have a new odometer
installed. The new one may read the correct mileage. This
is because your
car’s computer
has stored the mileage in memory. If it isn’t stored, then
this odometer
is set at zero, but a label on the driver’s door must show the
old reading and when the new one was installed.
WARNING LIGHTS
This section describes the warning lights that may De on your vehicle. The
pictures will help you locate them.

attention to your warning lights could also save you
or others from injury.

of your
vehicle’s functions.

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.
