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.

paper towel
or cloth, ' then push it back in all

again, keeping the tip
lower.

the oil is at or below
the ADD line, then
you’ll need
to add
some oil. But you must

the right kind. This

kind
of oil to use. For

To remove, turn the oil
fill cap to the left.
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:
Look for three things:
0 SG
“SG” must be on the oil container, either by itself or combined with
other quality designations, such as “SG/CC,” “SG/CD,” “SF,SG,CC,”
etc. These letters show American Petroleum Institute
(MI) levels of
quality.

FOR BEST FUEL ECONOMY AND COLD STARTING, SELECT THE LOWEST
SAE VISCOSITY GRADE OIL FOR THE EXPECTED TEMPERATURL RANGE.

Downloaded from www.Manualslib.com manuals search engine SAE 1OW-30
As shown in the viscosity 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
(16°C) before your next oil change. When it’s very cold, below
O°F
(-18”C), 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.

Oils with these words on the container will help you save fuel.
This doughnut-shaped logo (symbol) is used on most
oil containers to
help you select the correct
oil.
You should look for this on the oil container, and use only those oils that
display the logo.

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 vehicle is equipped with an Engine Oil
Life Index (EOLI) feature. Oil change intervals are determined by the
EOLI and will usually fall at, or between, the two recommended
alternative intervals of 3,000 miles
(5,000 kilometers) and 7,500 miles
(12,500 kilometers), but could be shorter than 3,000 miles (5,000
kilometers) under some very severe driving conditions shown in Schedule
I. The system will also indicate the need for an oil change if 7,500 miles
(12,500 kilometers) has been driven.
Engine oil life remaining is displayed through the Fuel Data center and as
a
“CHANGE OIL SOON” light. The Fuel Data center display includes a
number between
0 and 100. This is the percentage of oil life
REMAINING based on driving conditions and mileage driven since the
last time the oil life indicator was reset.
The EOLI will not detect excessively dusty conditions or engine
malfunctions which may effect the
oil. If you drive in dusty areas, change
the engine
oil after every 3,000 miles (5,000 kilometers) or 3 months
(whichever comes first), unless instructed to
do so sooner by the EOLI.

Downloaded from www.Manualslib.com manuals search engine How To Reset the Oil Life Indicator: After the oil has been changed,
press and hold the
“RANGE” and “RESET” buttons between 5 and 60
seconds. Once the buttons are released the “CHANGE OIL SOON”
light will flash 4 times to indicate it has reset to 100. If the “CHANGE
OIL SOON” light comes on for 5 seconds it did not reset. You will need
to reset the system again. The percentage
of oil life remaining may be
checked at any time by pressing the
“RANGE” and “FUEL USED” on
the Fuel Data center.
Engine Block Heater: An engine block heater can be a big help if you
have to park outside
in very cold weather, O°F (-18OC) or colder. If your
vehicle has this option, see “Engine Block Heater” in the Index.
What to Do with Used Oil:
’
A CAUTION:
Used engine oil contains things that have caused skin cancer in
laboratory animals. 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.
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 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.

To gain access to the
air cleaner element,
loosen the four screws
and lift the
top half of
the air cleaner
assembly.
Refer
to the
. 1 Maintenance Schedule
to determine when to
replace the air filter.
See “Scheduled Maintenance Services”
in the Index.
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

When 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 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.
Wait at least
30 minutes before checking the transaxle fluid level if you
have been driving:
0 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.
