For correct operation of the low oil sensing system, the vehicle should be
on a level surface. A false LOW OIL LEVEL message may appear if the
vehicle is parked
on grades. The oil level sensing system does not check
for actual oil
level if the engine has been off for a short period of time,
and the
oil level is never sensed while the engine is running. If the LOW
OIL LEVEL message appears, and your vehicle has been parked on level
ground with
the engine off for at least 30 minutes, your oil level should be
checked by observing the oil dipstick. Prior to checking your oil level be
sure your engine has
been off for five minutes and your vehicle is on a
level surface. Then check your dipstick and add oil if necessary. See
“Engine
Oil” in the Index.
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 you have used 90% of the engine oil’s
expected life, based on your driving patterns.
CHANGE ENGINE OIL - 82
This means that the life of your engine oil has expired and it should be
changed within 200 miles. See “Engine Oil” and “Filter
Recommendations”
in the Maintenance Schedule. After an oil change the
Oil Life Index must be resct. See “Oil Life Indicator” in the Index on how
to reset it.
CRUISE ENGAGED - 43
This message will appear for a few seconds when you select a speed at
which to cruise.
ENGINE COOLANT HOT - 44
This message will appear when your engine coolant temperature is over
248’ F (126’ C). To avoid added strain on a hot cngine turn off your
Climate Control system. Stop and allow your vehicle
to idle until it cools
down or the message is removed.
If it does not cool down, turn off 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.

Downloaded from www.Manualslib.com manuals search engine Road Sensing Suspension
The Road Sensing Suspension (RSS) automatically controls the ride of
your vchicle. The system controls damping forces in the shock absorbers
and struts
in response to various road and driving conditions. The system
is capable of making these changes
within milliseconds.
The Road Sensing Suspension controller is
a computer used to control
and monitor thc system.
The computer receives input from vertical rotary
position sensors, vehicle speed
sensors, lift and dive signals and
determines optimum strut valving (suspension stiffness) for your current
operating conditions. The computer
also receives feedback from the
various components to determine proper system operation.
If the
computer receives
an incorrect feedback from the system, an error code
will be set in memory and a SERVICE RIDE CONTROL message will
display on the Driver Information Center. If this message should appear,
have your vehicle serviccd
at your Cadillac dealership 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
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.

Downloaded from www.Manualslib.com manuals search engine 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
E320 km]).
The system should indicate to change the oil between 3,000 miles
(5 000 km) and 7,500 miles (12 500 km), but it may even indicate to
change it before 3,000 miles under very severe conditions. It all depends
on your driving patterns. If it’s been
7,500 miles (12 500 km), it indicates
to change the oil.
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 3,000 miles (5 000 km) or
three 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.
When You’ve Changed the Oil
When new oil is put in, you’ll need to reset your system. To do this, display
the OIL LIFE INDEX by pressing the INFORMATION button. Then
press and hold the
RESET buttons until the display shows 100 OIL LIFE

The Driver Information Center will display either ENGINE COOLANT

STOP ENGINE ENGINE OVERHEATING.
In addition you will find the warning light about a hot engine on your
instrument panel on Canadian vehicles.
Overheated Engine Protection Operating Mode
Should a low coolant condition exist and the message STOP ENGINE
ENGINE OVERHEATING is displayed, an overheat protection mode
which alternates firing groups of four cylinders helps prevent engine
damage. 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 may be severely degraded.
Change the oil and reset the
oil life indicator. See “Engine Oil,
When

for your vehicle. However, you
can use
SAE SW-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 SW-30.

Don’t add anything to your oil. Your Cadillac dealer is ready to advise if

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
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 “loo”. 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
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 cngine
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

A CAUTION:
Operating the engine with the air cleaner off can cause you or
others
to be burned. The air cleaner not only cleans the air, it
stops flame if the engine backfires. If it isn't there, and the
engine backfires, you could be burned. Don't drive with it off,
and be careful working on the engine with the air cleaner off.
