low. If this message is displayed, check the
oil and add as needed.
CHECK WASHER FLUID - 25
This message will appear for a few seconds indicating that you need
washer solvent.
CHANGE OIL SOON - 40
This message will appear when your engine oil is less than 10 percent or
the mileage since the last
oil change is more than 6750 miles.
CHANGE ENGINE OIL - 82
This means that the life of your engine oil has expired and it should be

your engine and have it serviced before driving it again. Severe engine
damage can result from an overheated engine. See “Engine Overheating”
in the Index.
ENGINE HOT - A/C COMPRESSOR OFF - 16
This message will appear when the Climate Control is in “Auto” or
“Defrost” and the engine coolant is hotter than the normal operating
temperature.

receives an incorrect feedback from the system, an error code
will be set
in memory and a “SERVICE RIDE CONTROC’ message will display on
the Driver Information Center. If this message should appear, have your
vehicle serviced at your Cadillac dealer at your earliest convenience.
Oil Life Indicator
This feature lets you know when to change your engine oil. It’s based
upon the engine oil temperatures and your driving patterns.
To see the display, press the Information button several times until
“XXX
OIL LIFE LEFT” appears.
You’ll
see how much oil life you have left, as a percentage. So, if you see
“95 OIL LIFE LEFT,” for example, that means that the way you’re
driving your car,
95% of your current oil life is still left.
The Oil Life Indicator may say
to change the oil sooner than your
maintenance schedule. This can happen
if driving conditions, such as
short trips
in cold weather, cause shorter oil life. Always keep a written
record of the mileage and date when you last changed your oil. For more
information on when to change your oil, see the Cadillac Maintenance
Schedule Booklet.
If you
see “CHANGE OIL SOON,” it means that you have less than 10%
of your 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 (certainly within 200 more miles
[320 km]).

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.

Don’t add anything to your oil. Your Cadillac dealer is ready to advise if
you think something should be added.
Men to Change Engine Oil
Your Cadillac has an “Oil Life Indicator.” This feature will let you know
when to change your oil
-- 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
without an oil change.

of oil life remaining may be checked at any time by pressing
the INFORMATION button several times until the “OIL LIFE LEFT”
message appears. For more information on the Oil Life Index feature, see
-
“Oil Life Index” in the Index.
Engine Coolant Heater (Engine Block Heater)
An engine coolant heater can be a big help if you have to park outside in
very cold weather,
0°F (-18°C) or colder. If your vehicle has this option,
see “Engine Coolant Heater” in the Index.

Downloaded from www.Manualslib.com manuals search engine What to Do with Used Oil
Did you know that used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer? Don’t let used oil
stay
on your skin for very long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly throw away clothing or
rags containing used engine
oil. (See the manufacturer’s warnings about
the use and disposal
of oil products.)
Used oil can be a real threat to the environment. If you change your own
oil, be sure to drain all free-flowing oil from the filter before disposal.
Don’t ever dispose of oil by putting it
in the. trash, pouring it on the
ground, into sewers, or into streams or bodies of water. Instead, recycle it
by taking it to a place that collects used oil. If you have a problem
properly disposing
of your used oil, ask your dealer, a service station or a
local recycling center for help.
AIR CLEANER
To gain access to the
filter loosen the four
screws and lift the top
half
of the air cleaner
assembly.
Refer to the
Maintenance Schedule
to determine when
to
replace the air filter.
See “Scheduled Maintenance Services’’
in the Index.
265

Downloaded from www.Manualslib.com manuals search engine NOTICE:
If the air cleaner is off, a backfire can cause a damaging engine
fire. And, dirt can easily get into your engine, which will damage
it. Always have the air cleaner
in place when you’re driving.
AUTOMMTIC TRANSAXLE FLUID
Men to Check and Change
A good time to check your automatic transaxle fluid level is when the
engine oil is changed. Refer to the Maintenance Schedule to determine
when to change your fluid. See “Scheduled Maintenance Services” in the
Index.
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.

the way.
ENGINE COOLANT 7
The following explains your cooling system and how to add coolant when (. I
it is low. If you have a problem with engine overheating, see “Engine
Overheating” in the Index.
The proper coolant for your Cadillac will:
0 Give freezing protection down to -34°F (-37OC) .
0 Give boiling protection up to 262 F (128 C) .
0 Prote-ct against rust and corrosion.
Help keep the proper engine temperature.
Let the warning-lights work as they shoula.
What to Use
Use a mixture of one-half clean water (preferably distilled) and one-half
antifreeze that meets
“GM specification 1825-M,” which won’t damage
aluminum parts. You can also use
a recycled coolant conforming to GM
