check engine CADILLAC FLEETWOOD 1994 Owners Manual

The alarm won’t stop if you try to unlock a door any other way.
How to Test The Alarm
r 0 From inside the vehicle roll down your window, then get out of your
vehicle keeping the door open.
0 From outside the vehicle with the door open, lock the vehicle using
the power door lock or the Keyless Entry System and close the door.
0 Once the interior lights are off, reach in and unlock the door using the
manual lock. Open the door, the horn will sound and your headlights
will flash.
If the alarm does not sound when it should, check to see
if the horn
works. The horn fuse may be blown. To replace the fuse, see “Fuses and
Circuit Breakers” in the Index.
To reduce the possibility of theft, always arm the theft deterrent system
when leaving your vehicle.
PASS-KEY@II
Your vehicle is equipped with the PASS-Key@II (Personalized
Automotive Security System) theft deterrent system. PASS-Key@II
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@II uses a resistor pellet in the
ignition key that matches a decoder in your vehicle.
When the PASS-Key@II 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 engine does not start and and the
“PASS
KEY FAULT” light comes on, the key may be dirty or wet. Turn
the ignition off.

Clean and dry the key. If the starter still won’t work, and 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 (see “Fuses and Circuit
Breakers” in the Index). If the starter won’t work with the other key, your
vehicle 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@II.
If you accidentally use a
key that has a damaged or missing resistor pellet,
the starter won’t work But you don’t have to wait three minutes before
trying one of the other ignition keys.
See your Cadillac dealer or a locksmith who can service the PASS-Key@II
to have
a new key made.
If you’re ever driving and the “PASS KEY FAULT” light comes on and
stays on, you will be able to restart your engine if you turn it off. Your
PASS-Key@II system, however, is not working properly and must be
serviced by your Cadillac dealer. Your vehicle is not protected by the
PASS-Key@II system.
If you lose or damage a PASS-Key@II ignition ke
, see your Cadillac
dealer or a locksmith who can service PASS-Key I1 to have a new key
made. J

NOTICE:
Your engine is designed to work with the electronics in your
vehicle.
If you add electrical parts or accessories, you could
change the
way the fuel injection system operates. Before
adding electrical equipment, check with your dealer.
If you
don’t, your engine might not perform properly.
If you ever have to have your vehicle towed, see the part
of this
manual that tells how to do it without damaging your vehicle.
See “Towing Your Vehicle’’ in the Index.

DmNG THROUGH DEEP STMDING
WATER
NOTICE:
If you drive too quickly through deep puddles or standing water,
water can come in through your engine’s
air intake and badly
damage your engine.
If you can’t avoid deep puddles or standing
water, drive through them very slowly.

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.
Traction Control System Lights
Traction Engaged
This light will go on as

r Oil Pressure Light
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 this 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.
NOTICE:
Damage to your engine from neglected oil problems can be
costly and is not covered by your warranty.

To save your battery until you get there, turn off all
accessories, and set your Electronic Climate Control system to
“OFF.”
Low Oil Level Light
If it doesn’t come on, have it repaired. If the light comes on and stays on,

If it stays on, or it comes on
while you are driving, the computer
is indicating that you have a problem.
You should take your vehicle in for service soon.
NOTICE:
If you keep driving your vehicle with this light on, after a while
the emission controls won’t work as well, your fuel economy
won’t be as good and your engine may not run as smoothly. This
could lead to costly repairs not covered by your warranty.

OIL LIFE INDICATOR
Your Cadillac has an Oil Life Indicator feature. This tells you when
you need to change your engine oil. It’s based upon the engine oil
temperatures and your driving patterns.
Your Oil Life Indicator may say to change the oil sooner than your
maintenance schedule. This can happen if driving conditions, such as
short trips in cold weather, cause shorter
oil life. Always keep a written
record of the mileage and date when you last changed your oil. For more
information on when to change your oil, see the Cadillac Maintenance
Schedule Booklet.
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 miles under severe conditions. It all depends on your driving
patterns. (If it doesn’t, or if it doesn’t even light up, then something is
wrong. You will need to have it serviced.)
There are
two things the system won’t do: 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 “CHANGE OIC’ light comes on sooner.
It doesn’t check how much oil you have
so you will still have to check for
that.
To check it, see the Index under “Engine Oil.”
When You’ve Changed the Oil
When new oil is put in, you’ll need to reset your system. To do that, turn
the ignition switch to the
“ON” position with the engine stopped. Fully
depress and release the accelerator pedal
3 times within 5 seconds.
If the “CHANGE OIC’ light comes on and stays on for 5 seconds, it did
not reset. You’ll need to reset the system again.

NOTICE:
Before you add any sound equipment to pour vehicle -- like a
. tape player, CB radio, mobile telephone or two-way radio -- be
sure you can add what you want.
If you can, it's very important
to do it properly. Added sound equipment may interfere with the
operation
of your vehicle's engine, Delco@ radio or other
systems, and even damage them. And, your vehicle's systems
may interfere with the operation
of sound equipment that has
been added improperly.
So, before adding sound equipment, check with your dealer and
be sure to check Federal'rules covering mobile radio and
telephone units.
FM Stereo
FM stereo will give you the best sound. But FM signals will reach only
about
10 to 40 miles (16 to 65 km). And, tall buildings or hills can
interfere with
FM signals, causing the popping, crackling, or a momentary
hissing sound.
AM
The range for most AM stations is greater than for FM, especially at
night. The longer range, however, can cause stations to interfere with
each other.
AM can pick up noise from things like storms and power
lines.
Try reducing the treble to reduce this noise if you ever get it.
Speed Sensitive Volume
Your Delco radio automatically adjusts the volume level to compensate
for road and wind noise as you are driving.
Dolby@
This feature automatically removes noise on Dolby encoded tapes (no
button is required).
*Dolby@ is a registered trademark of Dolby Laboratories.
