A CHECK OIL LEVEL message will appear when the engine oil is
approximately
a quart 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. ~-~
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.

Pull out the dipstick and clean it with a paper towel or cloth, then push it
back in all the way. Remove it again, keeping the tip lower, and check the
level.
When to Add Oil
If the oil is at or below the ADD line, then you’ll need to add some oil.
But you must use the right kind. This section explains what kind of oil to
use.
For crankcase capacity, see “Capacities and Specifications” in the
Index.
NOTICE:
-
Don’t add too much oil. If your engine has so much oil that the
oil level gets above the cross-hatch area that shows the proper
operating range, your engine could be damaged.
Page 274 of 399

Downloaded from www.Manualslib.com manuals search engine To remove, turn the oil fill cap counterclockwise.
Just
fill it enough to put the level somewhere in the proper operating
range. Push the dipstick all the way back in when you’re through.
What Kind of Oil to Use
Beginning midyear 1993, oils of the proper quality for your vehicle will be
identified
with this new “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.
You should look for this on the front of the oil container, and use only
oils that display this
new symbol.

DO NOT USE SAE 1OW-40, SAE 2OW-50 OR ANY OTHER GRADE OIL NOT RECOMMENDED
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 OF (16 C)
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 2OW-50.

Downloaded from www.Manualslib.com manuals search engine If you cannot find oils with the new “starburst” symbol on the front of the
container,
you should look for and use oils containing the following three
things:
-
SHor SG
“SH” or “SG” must be-on the oil container, either by itself or
combined with other quality designations, such as
“SH/CD,”
“SH,SG,CD,” “SG/CD,” etc. These letters show American Petroleum
Institute (MI) levels
of quality.
SAE 1OW-30
0 Energy Conserving I1
Oils with these words on the container will help you save fuel.
These three things are usually included in a doughnut shaped logo
(symbol) on most containers.
If you cannot find oils with the “starburst”
symbol,
you should look for oils with the doughnut shaped symbol,
containing the three things noted above.
NOTICE:
If you use oils that do not have either the “starburst” symbol or
an
API SH or SG designation, you can cause engine damage not
covered by your warranty.
GM Goodwrench@ oil (in Canada, GM Engine Oil) meets all the
requirements for your vehicle.

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.

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 ENGINE OK’ message is displayed. 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 (-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.

Page 279 of 399

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.

Page 280 of 399

Downloaded from www.Manualslib.com manuals search engine I NOTICE:
Too much or too little fluid can damage your transaxle. Too
much can mean that some of the fluid could come out and fall
on hot engine parts or exhaust system, starting a fire. Be sure to
get an accurate reading if you check your transaxle fluid.
Wait at least 30 minutes before checking the transaxle fluid level if you
have been driving:
When outside temperatures are above 90" F (32" C).
0 At high speed for quite a while.
In heavy traffic -- especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid should be at normal operating
temperature, which is
180 " F to 200 " F (82 C to 93 C).
Get the vehicle warmed up by driving about 15 miles (24 km) when
outside temperatures are above
50 F (10 C). If it's colder than 50 F
(10 " C), you may have to drive longer.
To check thefluid level
Park your vehicle on a level place.
With the parking brake applied, place the shift lever in "P" (Park).
With your foot on the brake pedal, move the shift lever through each
gear range, pausing for about three seconds in each range. Then,
position the shift lever in "P" (Park).
Let the engine run at idle for three to five minutes.
