Downloaded from www.Manualslib.com manuals search engine VERY LOW REFRIGERANT A/C COMPRESSOR
OFF - 12: This message means that the air conditioning
system detects
a refrigerant level that is low enough to
cause damage to the air conditioning compressor.
To avoid damage, the air conditioning compressor
automatically turns off and the Electronic Climate
Control will automatically switch from AUTO to AC
and remain there. Have the air conditioning system
serviced if this message appears.
Continuous Variable - Real Time Damping
(CV-RTD) (DeVille Concours Only)
The CV-RTD automatically adjusts the ride of your
vehicle. Automatic ride control is achieved through
a
computer controller used to control and monitor the
suspension system. The computer controller receives
inputs from various sensors to determine the proper
system response. If the computer controller detects a
problem within the system, the DIC will display a
SERVICE RIDE CONTROL message. If this
message appears, have your vehicle serviced at your Cadillac dealership.
Oil Life Indicator
This feature lets you know when to change the engine
oil. It's based on the engine oil temperatures and
your driving patterns.
To see the display, press the
INFORMATION (INFO) button until
XX OIL LIFE
LEFT appears.
If you see 99% OIL LIFE LEFT,
99 percent of your current oil life remains.

Downloaded from www.Manualslib.com manuals search engine The DIC may display a CHECK OIL LEVEL message.
Always keep a written record of the mileage and date
when you changed your oil. For more information, see
the Cadillac Maintenance Schedule booklet. If you see
CHECK
OIL LEVEL, it means that you have less than
10 percent of the oil life left and you should consider
changing your engine oil. If you see CHANGE
ENGINE OIL, it means the oil life is gone and you
should change the oil right away.
The system should indicate changing the oil between
3,000 miles (5 000 km) and 7,500 miles (12 500 km).
It may indicate changing the oil before 3,000 miles
(5 000 km) depending on your driving habits. If the vehicle has been driven
7,500 miles (12 500 km), it will
indicate to change the oil.
If you drive in a dusty area,
you should change your oil every
3,000 miles (5 000
km) or three months (whichever comes first) unless the
display indicates changing it sooner. The system 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.
When new oil
is added, you’ll need to reset the system.
To reset, display the Oil Life Indicator by pressing the
INFORMATION (INFO) button. Then press and hold
the RESET button until the display shows 100% OIL
LIFE LEFT.

Downloaded from www.Manualslib.com manuals search engine Some cleaning cassettes or CD adapter kits may appear
as a broken tape. If the cleaning cassette is ejected
immediately from the tape player, follow these steps for
the TAPE CLEAN OVERRIDE feature:
1. Turn the ignition to RUN or ACC.
2. Turn the radio off.
3. Press and hold the SOURCE button for three
seconds. After three seconds, the tape icon will flash
indicating the cut tape feature is now turned
off.
4.
Turn the radio on and insert the cleaning cassette (or
the CD adapter
kit).
5. Eject the tape after the tape player has been cleaned.
When the cleaning cassette has been ejected, the broken
tape detection feature is active again.
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 and, 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 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.
Power Antenna Mast Care
Your power antenna will look its best and work well
if it’s cleaned from time to time. To clean the
antenna mast:
1. Turn on the ignition and radio to raise the antenna.
2. Dampen a clean cloth with mineral spirits or
equivalent solvent.
3. Wipe the cloth over the mast sections, removing any dirt.

Downloaded from www.Manualslib.com manuals search engine 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 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:

Windshield Washer Fluid: Is the reservoir full? Are
all windows clean inside and outside?
Wiper Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked
all levels?
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?

Downloaded from www.Manualslib.com manuals search engine Three important considerations have to do with weight:
the weight of 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?
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.
If you have a DeVille or a DeVille d’Elegance without
the optional trailer towing package, the maximum trailer
weight is
1,000 lbs. (450 kg).
If you have a DeVille Concours, DeVille or a DeVille
d’Elegance 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 or the DeVille
d’Elegance to tow a trailer heavier than
1,000 lbs.
(450 kg). The DeVille 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 weight + trailer weight. The GCVW
should never weigh more than
8,100 lbs. (3 677 kg) total
loaded vehicle and trailer.

You really should not park your vehicle, with a trailer
attached, on a hill.
If something goes wrong, your rig
could start to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But if you ever have to park your rig on a hill, here’s
how to do it:
1. Apply your regular brakes, but do not shift into
PARK (P).
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then shift into
PARK (P) firmly and apply your parking brakes.
5. Release the regular brakes.
When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
0 Start your engine;
Shift into a gear; and
0 Be sure the parking brake has released.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
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.

axle inboard
of the spring.
Engine Overheating
You will find an ENGINE COOLANT HOT-IDLE
ENGINE message or a STOP ENGINE ENGINE
OVERHEATED message on the Driver Information
Center (DIC). There is also an engine temperature
warning light and/or gage on the instrument panel. See
“Engine Coolant Temperature Warning Light” or
“Engine Coolant Temperature Gage” in the Index.
Overheated Engine Protection
Operating Mode
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.
In this mode, you will notice a loss in power and engine
performance. 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.
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 will
be severely degraded. Repair
the cause
of coolant loss, change the oil and reset
the oil life indicator. See “Engine Oil, When to
Change” in the Index.

Downloaded from www.Manualslib.com manuals search engine When you decide it’s safe to lift the hood, here’s what
you’ll see:
A. Coolant Surge Tank with Pressure Cap
B. Electric Engine Fans
A CAUTION:
An electric fan under the hood can start up even
when the engine is not running and can injure
you. Keep hands, clothing and tools away from
any underhood electric fan.
If the coolant inside the coolant surge tank is boiling,
don’t do anything else until it cools down.
