Care of Your Cassette Tape Player
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 may cause failure of the tape player.
Your
tape player should be cleaned regularly after every
50 hours of use. Your radio may display CLN or CLEAN
TAPE to indicate that you have used your tape player for
50 hours without resetting the tape clean timer. Each time
the cassette
is cleaned, the 50 hour cassette timer should
be reset. This is done by holding down the eject button
for five seconds or until the
TAPE CLEAN message is
displayed. 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 with pads which scrub
the
tape head as the hubs of the cleaner cassette turn. It
is normal for the cassette
to eject while cleaning. Insert
the cassette at least six times to ensure thorough
cleaning.
A scrubbing action cleaning cassette is
available through your Cadillac dealer. You may
also choose a non-scrubbing action, wet-tyw
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 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.

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 Leaving on a Long Trip
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:

Lamps: Are they all working? Are the lenses clean?
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 weather 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?

Three important considerations have to do with weight: the trailer, the weight of the trailer tongue and the total
weight on your vehicle’s tires.
Weight of the Trailer
How heavy can a trailer safely be?
If you have a DeVille without the optional h-ailer towing
package,
the maximum trailer weight is 1,OOO lbs. (450 kg).
If you have a DeVille Concours or a DeVille with the
optional trailer towing package, the maximum trailer weight should never be more than
3,900 lbs. (1 773 kg)
total including the load. But even that can be too heavy.
The optional trailer towing package. provides the
necessary oil cooler for the DeVille to
tow a trailer
heavier than 1,OOO lbs.
(450 kg). The Concours is
equipped with this cooler as standard equipment.
The maximum trailer weight for your vehicle can
be
determined from the Gross Combined Vehicle Weight
(GCVW). The GCVW
= curb weight + passenger’s
weight
+ cargo + trailer weight, should never weigh more
than
8,200 lbs. (3 727 kg) total loaded vehicle and trailer.
It depends
on how you plan to use your rig. For
example, speed, altitude, road grades, outside
temperature and how much your vehicle
is used to pull a
trailer are all important. And, it can also depend on any
special equipment that you have on your vehicle, You
can ask your dealer for our trailering information or
advice, or you can write

Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important
weight
to measure because it affects the total capacity
weight
of your vehicle. The capacity weight includes the
curb weight
of the vehicle, any cargo you may carry in it
and the people who will be riding in the vehicle. And
if
you will tow a trailer, you must subtract the tongue load
from your vehicle’s capacity weight because your
vehicle will be carrying that weight, too. See “Loading Your Vehicle”
in the Index for more information about
your vehicle’s maximum load capacity.

Downloaded from www.Manualslib.com manuals search engine 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, belt, cooling system and brake adjustment.
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.

You will find an ENGINE COOLANT HOT-IDLE
ENGINE message
or a STOP ENGINE ENGINE
OVERHEATED message on the DIC. There is also an
engine temperature warning light
on the instrument
panel. See “Engine Temperature Warning Light” in the
Index.
Overheated Engine Protection Operating
Mode
Y
Should a low coolant condition exist and the message
STOP ENGINE
ENGINE OVERHEATED is displayed,
an overheat protection mode which alternates firing
groups
of four cylinders helps prevent engine damage.
This operating mode
allows your vehicle to be driven
to a safe place in
an emergency; you may drive up to
50 miles (80 km). Towing a trailer in the overheat
protection mode should be avoided.
I NOTICE:
After driving in the Overheated Engine
Protection Operating Mode,
to avoid engine
damage, allow the engine to cool before
attempting any repair. The engine oil may be
severely degraded. Change the
oil and reset the
oil life indicator. See “Engine Oil, When to
~ Change” in the Index.

A CAUTION:
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol,
can boil before the proper
coolant mix will. Your vehicle's coolant warning
system
is set for the proper coolant mix. With
plain water or the wrong mix, your engine could
get too hot but you wouldn't
get the overheat
warning. Your engine could catch fire and you
or
others could be burned. Use a 50/50 mix of clean
water and
DEX-COOL TM antifreeze.

A CAUTION:
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel
nuts
become loose after a time. The wheel could come
off and cause an accident. When you change a
wheel, remove any rust or dirt from the places
where the wheel attaches to the vehicle.
In an
emergency, you can use a cloth or a paper towel
to do this; but be sure to use a scraper or wire
brush later, if you need to, to get all the rust or
dirt off.
I A CAUTION:
~ ~~
Never use oil or grease on studs or nuts. If you
do, the nuts might come loose. Your wheel could
fall off, causing a serious accident.

nuts with the
rounded end of the
nuts toward the wheel. Tighten
each nut
by hand
until the wheel
is

In Canada, some gasolines contain an octane-enhancing
additive called
“T. If you use such fuels, your
emission control system performance may deteriorate
and
the malfunction indicator lamp on your instrument
panel may turn on. If this happens, return
to your
authorized Cadillac dealer for service.
To provide cleaner air, all gasolines are now required to
contain additives that will help prevent deposits from
forming
in your engine and fuel system, allowing your
emission control system
to function properly. Therefore,
you should not have to add anything to the fuel. In
addition, gasolines containing oxygenates, such as ethers
and ethanol, and reformulated gasolines may be
available
in your area to help clean the air. General
Motors recommends that you use these gasolines if they
comply with
the specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don’t use it. It can corrode
metal parts
in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.
Fuels in Foreign Countrics
If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard to
find. Never use leaded gasoline or any other fuel not
recommended in
the previous text on fuel. Costly repairs
caused by
use of improper fuel wouldn’t be covered by
your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where you’ll be driving.
You can also write us at the following address for
advice. Just tell us where you’re going and give your
Vehicle Identification Number (VIN).

oil, coolant,
brake fluid, windshield washer and
other fluids, and plastic or rubber. You
or others
could
be burned. Be careful not to drop or spill
things
that will burn onto a hot engine.
