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.

Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren’t touching
each other.
If they are, it could cause a ground
connection
you don’t want. You wouldn’t be able to
start
your Cadillac and the bad grounding could
damage the electrical systems.
Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter. Turn
off all lamps that aren’t needed as well
as radios. This will avoid sparks and help save both
batteries. In addition, it could save your radio!
Open the hoods and locate the batteries. Find the
positive
(+) and negative (-) terminals on
each battery.
An electric fan 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.
5. Start by removing the red positive (+)
terminal cover.

Steam from an overheated engine can burn you
badly, even
if you just open the hood. Stay away
from the engine if you see or hear steam coming
from
it. Just turn it off and get everyone away
from the vehicle until
it cools down. Wait until
there is no sign
af steam or coolant before you
open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire.
You or
others could be badly burned. Stop your engine
if
it overheats, and get out of the vehicle until the
engine
is cool.
NOTICE:
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered by your warranty. See “Overheated
Engine Protection Operating Mode”
in the Index.

If you get the overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little too hot when you:
Climb a long hill on a hot day.
0 Stop after high-speed driving.
0 Idle for long periods in traffic.
0 Tow a trailer.
If you get the overheat warning with no sign of steam,
try this for a minute or
so:
1. Turn off your air conditioner.
2. Dial temperature control to the highest heat setting
and open the window, as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- OVERDFUVE (a) or THIRD (3).
If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about
10 minutes.
If the warning doesn’t come back on, you can
drive normally.
If the warning continues, pull over, stop and park your
vehicle right away.
If there’s still no sign of steam, you can idle the engine
for two or three minutes while you’re parked, to see
if
the warning stops. But then, if you still have the
warning,
turn off the engine and get everyone out of the
vehicle
until it cools down. Also, see “Overheated
Engine Protection Operating Mode” listed previously in
this section.
You may decide not to lift the hood but to get service
help right away.

Downloaded from www.Manualslib.com manuals search engine Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around it. This may cause wind noise
and affect windshield washer performance. Check with
your Cadillac dealer before adding equipment to the
outside of your vehicle.
Fuel
Use premium unleaded gasoline rated at 91 octane
or higher. At a minimum,
it should meet specifications
ASTM D4814
in the United States and CGSB 3.5-M93
in Canada. Improved gasoline specifications have been
developed by the American Automobile Manufacturers
Association (AAMA) for better vehicle performance
and engine protection. Gasolines meeting the AAMA
specification could provide improved driveability
and emission control system protection compared to
other gasolines.
Be sure the posted octane for premium is at least 91.
If the octane is less than 91, you may get a heavy
knocking noise when you drive. (In an emergency, you
may be able to use a lower octane
-- as low as 87 -- if
heavy knocking does not occur.) If you’re using 91 or
higher octane unleaded gasoline and you hear
heavy knocking, your engine needs service. If
your vehicle is certified to meet California Emission
Standards (indicated on the underhood tune-up label),
it is designed to operate on fuels that meet California
specifications.
If such fuels are not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily
on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp on
your instrument panel may turn on and/or your vehicle
may fail a smog-check test. If this occurs, return to your
authorized Cadillac dealer for diagnosis to determine the
cause of failure.
In the event it is determined that the
cause
of the condition is the type of fuels used, repairs
may not be covered by your warranty.
Some gasolines that are not reformulated for low
emissions contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl (MMT);
ask your service station operator whether or not this fuel
contains
MMT. General Motors does not recommend
the use of such gasolines. If fuels containing MMT
are used, spark plug life may be reduced and your
emission control system performance may be affected.
The malfunction indicator lamp on your instrument
panel may turn on. If this occurs, return to your
authorized Cadillac dealer for service.

If you have the Driver Information Center (DIC), a
CHECK OIL LEVEL message will appear when the
engine oil is approximately
1 quart (1 L) low. If the
message is displayed, check the dipstick level and add
oil as needed. It’s
a good idea to check your
engine oil every time you
get fuel. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
.. .......... The engine oil dipstick is
located behind the radiator on the driver’s side
of the
engine. The black handle
says ENGINE
OIL on it.
Turn
off the engine and give the oil a few minutes to
drain back into the oil pan.
If you don’t, the oil dipstick
might not show the actual level.
