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.

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.

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.

Downloaded from www.Manualslib.com manuals search engine Here are some cleaning tips:
Always read the instructions on the cleaner label.
Clean up stains as soon as you can -- before they set.
Use a clean cloth or sponge, and change to a clean area often. A soft
brush may be used
if stains are stubborn.
Use solvent-type cleaners in a well-ventilated area only. If you use
them, don’t saturate the stained area.
If a ring forms after spot cleaning, clean the entire area immediately
or it will set.
Cleming Leather
Use a soft cloth with lukewarm water and a mild soap or saddle soap.
For stubborn stains, use a mild solution of
10% isopropyl alcohol
(rubbing alcohol) and
90% water.
Never use oils, varnishes, solvent-based or-abrasive cleaners; furniture
Soiled leather should be cleaned immediately. If dirt is allowed to

Then dry it immediately with a blow dryer or a heat lamp.
NOTICE:
Be careful with a hair dryer or heat lamp. You could scorch the
fabric.
Wipe with a clean cloth.
Using Solvent-Type Cleaner on Fabric
.-
.-
First, see if you have to use solvent-type cleaner at all. Some spots and
stains
will clean off better with just water and mild soap.
If you need to use a solvent:
Gently scrape excess soil from the trim material with a clean, dull
knife or scraper. Use
very little cleaner, light pressure.and clean cloths
(preferably cheesecloth). Cleaning should start at the outside of the
stain, “feathering” toward
the center. Keep changing to a clean
section of the cloth.
When you clean a stain from fabric, immediately dry the area with an
air hose, hair dryer, or heat lamp
to help prevent a cleaning ring. (See
the previous NOTICE.)
