1994 CADILLAC DEVILLE service

Downloaded from www.Manualslib.com manuals search engine 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 under very severe conditions. It all depends on your driving
patterns. If it’s been
7500 miles (12500 km) it always says to change the oil.
There are
two things the system doesn’t do:
0 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 display says to change
it even sooner than that.
It doesn’t check how much oil you have, so you’ll still have to check
for that.
To see how, see Engine Oil in the Index.
men You’ve Changed the Oil
When new oil is put in, you’ll need to reset your system. To do it, display
the “OIL LIFE INDEX” by pressing the INFORMATION button. Then
press and hold the RESET buttons until the display shows
“100 OIL
LIFE LEFT”
Electronic Level Control
This keeps your car level.
The ignition has to be “ON” for the level control to work. When you turn
the ignition off, you may hear the level control exhausting. The system
consists
of an electronic height sensor, a small electric air compressor,
and air adjustable shock absorbers mounted on the rear
of the vehicle.
If the system has a slight leak, the air compressor will run frequently for a
few seconds each time.
For
a massive air leak, the air compressor will stay on for approximately
7 minutes. You should see your dealer for service, but you can keep
driving your Cadillac.

A tape player that is not cleaned regularly can cause reduced sound
quality, ruined cassettes, or a damaged mechanism. Cassette tapes should
be stored in their cases away from contaminants, direct sunlight, and
extreme heat. If they aren't, they may not operate properly or cause
failure
of the tape player.
Your tape player should be cleaned after every
50 hours of use. If you
notice
a reduction in sound quality, try a known good cassette to see if the
tape
or the tape player is at fault. If this other cassette has no
improvement
in sound quality, clean the tape player.
Cleaning may be done with a scrubbing action, non-abrasive cleaning
cassette. This system uses a cleaning cassette with pads which scrub the
tape head as the hubs of the cleaner cassette turn. It is normal for the
cartridge to eject while cleaning. Insert the cassette at least
3 times to
ensure thorough cleaning.
A scrubbing action cleaning cassette is
available through your Cadillac dealership.
You may also choose a non-scrubbing action, wet-type cleaner which uses
a cassette with a fabric belt to clean the tape head. This type
of cleaning
cassette will
not eject. It may not clean as thoroughly as the scrubbing
type cleaner.
Cassettes are subject
to wear and the,sound quality and may degrade over
time. Always make sure that the cassette tape is
in good condition before
you have your tape player serviced.
Care of Your Compact Discs
Handle discs carefully. Store them in their original cases or other
protective cases and away from direct sunlight and dust. If the surface
of
a disc is soiled, dampen a clean, soft cloth in a mild, neutral detergent
solution and clean it, wiping from the center
to the edge.
Be sure never
to touch the signal surface when handling discs. Pick up
discs by grasping the outer edges or the edge of the hole and the
outer edge.

Once you are moving on the freeway, make certain you allow a
reasonable following distance. Expect to move slightly slower at night.
When you want
to leave the freeway, move to the proper lane well in
advance.
If you miss your exit do not, under any circumstances, stop and
back up. Drive on to the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce your speed according to your speedometer, not to your sense of
motion. After driving for any distance at higher speeds, you may tend to
think you are going slower than you actually are.
BEFORE LEAVTNG ONA LONG THP
Make sure you’re ready. Try to be well rested. If you must start when
you’re not fresh
-- such as after a day’s work -- don’t plan to make too
many miles that first part
of the journey. Wear comfortable clothing and
shoes you can easily drive in.
Is your vehicle ready for a long trip? If you keep it serviced and
maintained, it’s ready to
go. If it needs service, have it done before
starting out.
Of course, you’ll find experienced and able service experts in
Cadillac dealerships all across North America. They’ll be ready and
willing to help if
you need it.
Here are some things you can check before a trip:
0 Windshield Washer Fluid: Is the reservoir full? Are all windows clean
inside and outside?
Wiper Blades: Are they in good shape?
0 Fuel, Engine Oil. Other Fluids: Have you checked all levels?
Lights: Are they all working? Are the lenses clean?

Downloaded from www.Manualslib.com manuals search engine 0 Tires: They are vitally important to a safe, trouble-free trip. Is the
tread good enough for long-distance driving? Are the tires all inflated
to the recommended pressure?
- Weather Forecasts: What’s the weamer outlook along your route?
Should you delay your trip a short time to avoid
a major storm
system?
__ Maps: Do you have up-to-date maps?
HIGmAY HKPNOSIS
c_ Is there actually such a condition as “highway hypnosis”? Or is it just
plain falling asleep at the wheel? Call it highway hypnosis, lack of
awareness, or whatever.
There is something about an easy stretch
of road with the same scenery,
along with the hum of the tires on the road, the drone
of the engine, and
the rush
of the wind against the vehicle that can make you sleepy. Don’t
let it happen to you! If it does, your vehicle can leave the road in less than
a second, and you could crash and be injured.
What can you do about highway hypnosis? First, be aware that it can
happen. -_
__
Then here are some tips:
Make sure your vehicle is well ventilated, with a comfortably cool
interior.
Keep your eyes moving. Scan the road ahead and to the sides. Check
If you get sleepy, pull off the road into a rest, service, or parking area
your
rearview mirrors and your instruments frequently.
and take a nap, get
some exercise, or both. For safety, treat drowsiness
on the highway as an emergency.

4. Stop and have someone pick up and store the chocks.
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 (32’Celsius) with a loaded vehicle and trailer.
Stopping after high-speed driving.
Idling for long periods in stop and go traffic.
If “ENGINE
HOT A/C COMPRESSOR OFF” message appears on the
Driver Information Center, do not be alarmed. This is a normal function
designed to reduce the load on the engine and cooling system you can
continue to drive your vehicle.
If “ENGINE COOLANT
HOT” message appears on the Driver
Information Center, pull off 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. 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 “ENGINE COOLANT HOT”
message
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 more on this. Things that are
especially important
in trailer operation are automatic transaxle fluid
(don’t overfill), engine oil, belts, cooling system, and brake wear. Each of
these is covered
in this manual, and 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 nuts and bolts are tight.

good there, but the chance of sparks getting back to the
battery is much less.
