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 your maintenance schedule booklet. After an
oil
change the Oil Life Index must be reset. 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 (126O C). To avoid added strain on a hot engine 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.

The Road Sensing Suspension (RSS) automatically controls the ride of
your vehicle. 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 the system. The computer receives input from vertical rotary
I__
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 serviced at your Cadillac dealership at your earliest
convenience.

What Kind of Oil to Use
Oils of the proper quality for your vehicle can be identified by looking for
the “Starburst” symbol. The “Starburst” symbol indicates that the oil has
been certified by the American Petroleum Institute (API), and is
preferred for use
in your gasoline engine.
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 Institute
certified for
gasoline engines.

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°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 20W-50.
NOTICE:
Use only engine oil with the American Petroleum Institute

use the proper oil can result in engine damage not covered

requirements
for your vehicle.
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 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

An engine coolant heater can be a big help if you have to park outside in
very cold weather,
O°F (-HOC) or colder. If your vehicle has this option,
c- see “Engine Coolant Heater” in the Index.
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.
