1994 CADILLAC FLEETWOOD maintenance schedule

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.

Engine Cooling When Trailering
Your cooling system may temporarily overheat during severe operating
conditions such as;
Climbing grades steeper than 4% at ambient temperatures above
90’Fahrenheit (32O Celsius)
with a loaded vehicle and trailer.
0 Stopping after high-speed driving.
0 Idling for long periods in stop and go traffic.
If the “TEMP” warning light comes on, pull
to the side of the road as
soon as it is safe to do
so. When the vehicle is at a complete stop, shift the
transmission selector to P (Park) and allow the engine to idle. If your
Electronic Climate Control system is on, shut it
off. Do not turn off the
engine or increase engine speed above a normal idle. Within
two or three
minutes the system should cool sufficiently to allow A/C operation to
resume. At that time resume driving at a reduced speed. Return to
normal driving after
10 minutes if the “TEMP” warning light is not
displayed.
Maintenance when Trailer Towing
Your vehicle will need service more often when you’re pulling a trailer.
See the Maintenance Schedule for details. Things that are especially
important in trailer operation are automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, engine drive belt, cooling system, and
brake adjustment. Each of these is covered in this manual. The Index will
help you find them quickly. If you’re trailering, it’s a good idea to review
these sections before you start your trip.
Check periodically to
see that all hitch attaching nuts and bolts are tight.

rags containing used engine oil. (See the manufacturer’s warnings about
the use and disposal of oil products.)
Used oil can be a real threat to the environment.
If you change your own
oil, be sure to drain all free-flowing oil from the filter before disposal.
Don’t ever dispose of oil by putting.it
in the trash, pouring it on the
ground, into sewers, or into streams or bodies
of water. Instead, recycle it
by taking it to a place that collects used oil. If you have a problem
properly disposing of your used oil, ask your dealer, a service station or a
local recycling center for help.
AIR CLEANER

See “Scheduled Maintenance Services” in the Index. Refer
to the
Maintenance Schedule
to determine when to
replace the air filter.

If the air cleaner is off, a backfire can cause a damaging engine
fire:And, dirt can easily get into your engine, which will damage
it. Always have the air cleaner in place when you’re driving. I
I AUTOAUTIC .TRANsIMISSION FLUID
‘When to Check and Change
A good time to check your automatic transmission fluid level is when the
engine oil is changed. Refer to the Maintenance Schedule to determine
when to change your fluid. See “Scheduled Maintenance Services” in
the Index.
How to Check
Because this operation can be a little difficult, you may choose to have
this done at .a Cadillac dealership Service Department.
If you do it yourself, be sure to follow all the instructions here, or you
cou.ld get a false reading on the dipstick.
I I Too NOTICE: much or too little fluidcan damage your. transmission. Too
much can mean that some of the fluid could come out and fall
on hot engine parts or exhaust system, starting
a fire. Be sure to
get an accurate reading
if you check your transmission fluid. i
I
Wait at least 30 minutes before checking the transmission fluid level if
you
have been driving:
When outside temperatures are above 90°F (32OC).
At high speed for. quite a while.

How to Add Fluid
Refer to the Maintenance Schedule to determine what kind of
transmission fluid to use. See “Recommended Fluids and Lubricants” in
the Index.
If the fluid level is low, add only enough of the proper fluid to bring the
level up to the COLD area for a cold check
or the HOT area for a hot
check. It doesn’t take much fluid, generally less than a int.
Don’t overfill.
We recommend you use only fluid labeled DEXRON -111 or
DEXRON@-IIE, because fluids with that label are made especially for
your automatic transmission. Damage caused by fluid other than
DEXRON@-I11 or DEXRON@-IIE is not covered by your new vehicle
warranty. 8

When to Check and Change Lubricant
Refer to the Maintenance Schedule to determine how often to check the
lubricant and when to change it. See “Periodic Maintenance Inspections”
in the Index.
How to Check Lubricant
If the level is below the bottom of the filler plug hole, you’ll need to add
some lubricant. Add enough lubricant to raise the
level to the bottom of
the filler plug hole.

What to Add
Refer to the Maintenance Schedule to determine what kind of fluid to
use. See “Recommended Fluids and Lubricants” in the Index.

NOTICE:
When adding power steering fluid or making a complete fluid
change, always use the proper fluid. Failure to use the proper
fluid can cause leaks and damage hoses and seals.

“WASHER FLUID
ONLY.” Add washer

full.

put in, the fluid level goes back up. The other reason is that fluid is
leaking out of the brake system.
If it is, you should have your brake
system fixed, since a leak means that sooner or later your brakes won’t
work well, or won’t work at all.
So, it isn’t a good idea to “top off” your
brake fluid. Adding brake fluid won’t correct a leak. If you add fluid when
your linings are worn, then you’ll have too much fluid when you get new
brake linings. You should add (or remove) brake fluid, as necessary, only
when work is done on the brake hydraulic system.
Refer to the Maintenance Schedule to determine when to check your
brake fluid. See “Periodic Maintenance Inspections” in the Index.
