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 “XX 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]) .
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.
151

Downloaded from www.Manualslib.com manuals search engine There are two things the system doesn’t do:
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.
0 It doesn’t check how much oil you have, so you’ll still have to check
for that. To see how, see Index under “Engine Oil.”
When 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 rear position 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, though.

you can use
SAE 5W-30 if it's going to be colder than 60°F (16OC)
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 1OW-40 or SAE 20W-50.

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
-- 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 (12 000 km) or 12 months
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 Oil Soon” light 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.
How to Reset the Oil Life Indicator
After the oil has been changed, display the “OIL LIFE LEFT” message
by pressing the INFORMATION button. Then press and hold the
RESET button until the display shows “100”. This resets the
oil life index.
The message will remain off until the next oil change
is needed. The
percentage
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 (-18OC) 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
Refer to the Maintenance Schedule to determine when to replace the air
filter.
See “Scheduled Maintenance Services”
in the Index.
See “Air Cleaner Filter Replacement” in the Index.

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 TRASAXLE 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 De a little difficult, you may choose to have
this done at
a 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.

Downloaded from www.Manualslib.com manuals search engine ENGINE 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.
The proper coolant for your Cadillac will:
Give freezing protection down to -34OF (-37 C).
0 Give boiling protection up to 262OF (128OC).
0 Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights work as they should.
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
Specification 1825-M with a complete coolant flush and refill. Use GM
Engine Coolant Supplement (sealer) with any complete coolant change.
If you use this mixture, you don’t need to add anything else.

Downloaded from www.Manualslib.com manuals search engine The Northstar engine is designed to minimize the need for routine
maintenance while incorporating systems to remind the driver when
service is required.
An oil life index indicator monitors ongoing operating
conditions and reminds the driver when an oil change is needed.
A low
coolant warning message keeps track of the level of this vital fluid. Direct
acting hydraulic tappets provide maintenance free zero lash operation of
the
32 valves from idle to the 6500 rpm redline. The camshafts are driven
by a
two stage roller chain assembly which is designed to provide quiet
maintenance free operation. Platinum tipped spark plugs increase the
replacement interval to
100,OO miles.
The four valves per cylinder design provides more efficient engine
breathing, resulting in higher power than comparable
two valve engines.
The induction system uses smooth thermoplastic tubes
to channel air into
the cylinders. These smooth tubes simulate the elaborate port polishing
methods used on racing engines. The shape and length
of the tubes
boosts horsepower by using sonic pressure waves created by the motion of
the inlet valves to increase the amount
of air entering each cylinder. Once
the intake charge has entered the cylinder, the centrally located spark
plug ensures fast and efficient burning of the fuel/air mixture.
This engine is designed to be very durable. The aluminum block has
cast-in-place iron cylinder liners for greater wear resistance. High
strength connecting rods support the
free floating piston pins in bronze
bushings for superior high speed performance.
The fillets of the nodular
iron crankshaft undergo a high pressure compression rolling operation to
improve their resistance to fatigue.
Quiet operation is enhanced by the use
of special materials and designs.
The front cover of the engine is stamped from laminated steel which
damps out noise. Special cam cover gasket seals isolate va1v.e train
operation. The fuel injectors are placed inside the induction system
housing to eliminate the clicking noise which
is common to other fuel
injected engines.
The Northstar engine is designed to provide years
of efficient, reliable,
satisfying operation.
