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:
e SHorSG
“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,” etc. These letters show American Petroleum Institute
(MI) levels of quality.

e Enerm 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

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.
261

Downloaded from www.Manualslib.com manuals search engine 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).
At high speed for quite a while.
a 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 the fluid 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.

1. Pull out the dipstick.
2. Using a long-neck funnel, add enough fluid at the dipstick hole to
bring it to the proper 1evel.It doesn’t take much fluid, generally less
than a pint (OSL).
Don’t overfill. We recommend you use only fluid
labeled DEXR0N’-IIE or DEXRON@-111, because fluids with that
label are made especially for your automatic transaxle. Damage
caused by fluid other than DEXR0N’-IIE or DEXRON@-I11 is not
covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as described under “How to
Check.”
When the correct fluid level is obtained, push the dipstick back in all

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 If you use an improper coolant mix, your engine could overheat
and be badly damaged. The repair cost wouldn’t be covered by
your warranty.
Too much water in the mix can freeze and crack
the engine, radiator, heater core and other parts.
