1. Turn off the engine.
2. Open tl hood and unwrap the electrical’cord.
3. Plug it into a normal, grounded 1 10-volt AC outlet.
A CAUTldN:
I I
1 .gging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind
of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into
a properly grounded three-prong
110-volt
AC outlet. If the cord won’t reach, use a
heavy-duty three-prong extension cord rated for
at least 15 amps.
4. Before starting the engine, be sure to unplug and store
the cord as it was before to keep it away from moving
engine
parts. If you don’t, it could be damaged.
How long should you keep the coolant heater ph ged
in? The answer depends on the outside temperature, the
kind
of oil you have, and some other things. Instead of
trying to list everything here, we ask that you contact
your Cadillac dealer
in the area where you’ll be parking
your vehicle. The dealer can give you the best advice for
that particular area.

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.

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 What Kind of Oil to Use
Oils recommended for your vehicle can be identified
by looking for the “Starburst”
symbol. This symbol
indicates that the oil has been certified by the American
Petroleum Institute (API).
Do not use any oil which
does not
carry this Starburst symbol.
If you change your own
oil, be sure you use oil
that has the Starburst
symbol on the front of the
oil container.
If you have
your oil changed for you,
be sure the oil put into
your engine is American
Petroleum InstitGte certified
for gasoline engines.
You should also use the proper viscosity oil for your
vehicle, as shown in the following chart:
RECOMMENDED SAE VISCOSITY GRADE ENGINE OILS
FOR B€ST FUEL ECONOMY AND COLD STARTING, SELECT THE LOWEST
SAE VISCOSITY GRADE OIL FOR
THE EXPECTED TEMPERATURE RANGE.
HOT
WEATHER
COLD
WEATHER
LoOK
FOR THIS
SYMBOL
DO NOT USE SAE 2OW-50 OR ANY OTHER GRADE OIL NOT RECOMMENDED
6-12

Downloaded from www.Manualslib.com manuals search engine As shown in the chart, SAE 1OW-30 is best for your
vehicle. However, you can use SAE 5W-30
if it’s
going to be colder than
60 OF ( 16 O C) before your
next oil change. When it’s very cold, you should use
SAE 5W-30. These numbers on an oil container show its
viscosity, or thickness.
Do not use other viscosity oils,
such as
SAE 20W-50.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
(‘Starburst” symbol. Failure to use the
recommended oil can result in engine damage not
covered by your warranty.
I I
GM Goodwrench@ oil meets all the requirements for
your vehicle.
If you are in an area where the temperature falls below
-20°F (-29”C), consider using either an SAE 5W-30
synthetic oil or an SAE OW-30 oil. Both will provide
easier cold starting and better protection for your engine
at extremely low temperatures.
Engine Oil Additives
Don’t add anything to your oil. Your Cadillac dealer is
ready to advise if
you think something should be added.
When to Change Engine Oil
Your Cadillac has an Oil Life Indicator. This feature
will
let you know when to change your oil and
filter
-- usually between 3,000 miles (5 000 km) and
7,500 miles (12 500 km) since your last oil change.
Under severe conditions, the indicator may come
on
before 3,000 miles (5 000 km). Never drive your vehicle
more than
7,500 miles (12 500 km) or 12 months
(whichever occurs first) without an oil change.
The system won’t detect dust in the oil.
So, if you
drive
in a dusty area, be sure to change your oil
every 3,000 miles
(5 000 km) or sooner if the
CHANGE
ENGINE OIL message comes on.
Remember to reset the Oil Life Indicator when the
oil has been changed. For more information, see
“Oil Life Indicator” in the Index.

Downloaded from www.Manualslib.com manuals search engine Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle fluid
level
is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83
000 km) if the vehicle is mainly driven under one or
more of these conditions:
0 In heavy city traffic where the outside temperature
regularly reaches
90°F (32°C) or higher.
0 In hilly or mountainous terrain.
0 When doing frequent trailer towing.
0 Uses such as found in taxi, police or delivery service.
Use such as limousine service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.
See “Scheduled Maintenance Services”
in the
Maintenance Schedule booklet.
How to Check
Because this operation can be a little difficult, you may
choose to have this done at your Cadillac dealership
service department.
If you do it yourself, be sure to follow
all the instructions
here,
or you could get a false reading on the dipstick.
NOTICE:
Too much or too little fluid can damage your
transaxle.
Too much can mean that some of the
fluid could come out and fall on hot engine parts or exhaust system parts, starting a
fire. Be sure to
get an accurate reading if you check your
transaxle fluid.
Wait at least 30 minutes before checking the transaxle
fluid level if you have been driving:
When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
0 In heavy traffic -- especially in hot weather.
e While pulling a trailer.

Downloaded from www.Manualslib.com manuals search engine How to Reset Transaxle Fluid
Change Indicator
Your vehicle is equipped with a transaxle fluid change
indicator.
A CHANGE TRANS FLUID message will
display
on the Driver Information Center (DIC) when
the powertrain computer determines
that the transaxle
fluid needs to be changed or at each
100,000 miles
(160 000 km) interval, whichever occurs first. When
this message appears, change the transaxle fluid and
reset
the transaxle fluid life indicator as follows:
1. Turn the ignition on but do not start the engine.
2. Press and hold the OFF and rear defog buttons on the
climate control at the same time until the
TRANS
FLUID RESET message appears on the DIC.
Engine Coolant
The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant is designed
to remain
in your vehicle for 5 years or 150,000 miles
(240 000 km) whichever occurs first, if you add only
DEX-COOL’ extended life coolant.
The following explains your cooling system and how
to add coolant when it is low. If you have a problem
with engine overheating, see “Engine Overheating” in
the Index.
J
A 50/50 mixture of water and DEX-COOL@
coolant will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 “F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.
NOTICE: ~ ~~ ~ -
When adding coolant, it is important that you
use only
DEX-COOL@ (silicate-free) coolant.
If coolant other than DEX-COOL@ is added to
the system, premature engine, heater core or
radiator corrosion may result. In addition, the
engine coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. Damage caused by the use
of coolant other than DEX-COOL@ is not
covered by your new vehicle warranty.
