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 01 a local recycling
center for help.

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 flames
if the
engine backfires.
If it isn’t there, and the engine
backfires, you could be burned.
Don’t drive with
it
off, and be careful working on the engine with
the air cleaner
off.
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.
A good time to check your automatic transaxle fluid
level is when
the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under one
or more of these conditions:
In heavy city traffic where the outside temperature
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, the
fluid and filter do not require changing.
See “Scheduled Maintenance Services” in the
Maintenance Schedule booklet. regularly reaches
90°F (~32°C) or higher.

Downloaded from www.Manualslib.com manuals search engine 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.
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 parts, 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:
0 When outside temperatures are above 90°F (32°C).
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 not-mal
operating temperature, which is 180°F to 200'F
Get the vehicle warmed up by driving about 15 miles
(24 km) when outside temperatures are above 50°F
(10OC). If it's colder than 50°F (lO"C), you may have
to drive longer.
(820~ to 93"~).

Downloaded from www.Manualslib.com manuals search engine Adding only plain water to your cooling system
can be dangerous. Plain water? or some other
liquid like alcohol, can boil before
the proper
coolant mis will. Your vehicle’s coolant warning
system is set
for the proper coolant mix. With
phi11 water or the wrong mix, your engine could
get too hot but you wouldn’t get the overheat
warning. Your engine could catch fire and you or
others could be burned.
Use a 50/50 mix of clean
water and
DEX-COOL@ coolant.
NOTICE:
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.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
I NOTICE:
If you use the proper cooIant, you don’t have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.

It is not necessary to regularly check power steering
fluid unless you suspect there is
a leak in the system or
you hear an unusual noise. A fluid loss in this system
could indicate
a problem. Have the system inspected
and repaired. When
the engine compartment
is cool, wipe the cap and
the top of the reservoir clean, then unscrew the cap and
wipe the dipstick with
a clean rag. Replace the cap and
completely tighten it. Then
remove the cap again and
look at
the fluid level on the dipstick.
The level should be at the FULL
COLD mark. If
necessary, add only enough fluid to bring the level up
to the mark.
To determine what kind
of fluid to use. see
“Recommended Fluids and Lubricants” in the Index.
Always
use the prpper fluid. Failure to use the proper
fluid can cause leaks and damage hoses and seals.
