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. The engine oil dipstick
is
located behind
the radiator
on the driver's side of the
engine. The black handle
says ENGINE OIL on it.
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 If the oil is at or below the ADD line, then you’ll need
cloth, then push
it back in all the way. Remove it again, to add some oil. But you must use the right kind. This

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 upper
mark that shows the proper operating range,
your engine could be damaged.

The oil fill cap is located
behind the radiator
on the
L
~ passenger’s side of the
~ engine. Turn the cap
1 counterclockwise to
remove.
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
Oils recommended for your vehicle can be identified by
looking for the “Starburst” symbol. This symbol
indicates that the oil has been certified by the American
Petroleum Institute
(API). Do not use any oil which
does not carry this Starburst symbol.
If you change your own
oil, be sure you use oil
that has the Starburst
symbol on the front
of the
oil container. If you have
your oil changed for you,
be sure the oil put into
your engine
is American
Petroleum Institute certified
for gasoline engines.
You should also use the proper viscosity oil for your
vehicle, as shown in the following chart:

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 20W-50.
I NOTICE:
Use only engine oil with the American Petroleum

When to Change Engine Oil
Your Cadillac has an Oil Life Indicator. This feature
will let you know when to change your oil and
filter
-- 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 OOO km). Never drive your vehicle
more than
7,500 miles (12 500 km) or 12 months,
(whichever occurs first) 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 OIL message 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 Indicator” in the Index.
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.

Automatic Transaxle Fluid
When to Check and Change
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 0oO 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.
regularly reaches
90°F (32°C) or higher.
0 When doing frequent trailer towing.
0 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.
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.
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 parts, starting a fire. Be sure to
get an accurate reading if
you check your
transaxle fluid.

Downloaded from www.Manualslib.com manuals search engine Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL (orange-colored, silicate-free) engine
coolant. This coolant is designed to remain in your vehicle for
5 years or 100,000 miles (166 0o0 km),
whichever occurs first.
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.
A 50/50 mixture of water and the proper coolant for
your Cadillac will:
Give freezing protection down to -34°F (-37 O C).
Give boiling protection up to 265 “F (129 “C).
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
Let the warning lights and gages work as they should.
NOTICE:
When adding coolant it is important that you use
DEX-COOL TM (orange-colored, silicate-free)
coolant meeting
GM Specification 6277M.
If silicated coolant is added to the system,
premature engine, heater core or radiator
corrosion may result. In addition, the engine
coolant
will require change sooner -- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first.
What
to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL (orange-colored,
silicate-free) antifreeze that meets
GM Specification
6277M, which won’t damage aluminum parts. Use
GM Engine Coolant Supplement (sealer) (GM Part
No. 3634621) with any complete coolant change. If you
use this mixture, you don’t need
to add anything else.
A special procedure is required for adding sealer; see the
Cadillac service manual.
(To order a service manual, see
“Service and Owner Publications”
in the Index.)

A CAUTION:
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 mix will. Your vehicle’s coolant warning
system is set for the proper coolant mix. With
plain 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 (orange-colored,
silicate-free) antifreeze.
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.
[f you have to add coolant more than four times a year,
lave your dealer check your cooling system.
NOTICE:
If you use the proper coolant, you don’t have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.

What to ,Add
When
you do need brake fluid, use only DOT-3 brake
fluid
-- such as Delco Supreme 11@ (GM Part
No. 1052535). Use new brake fluid from a sealed
container only,
and always clean the brake fluid
reservoir cap before removing
it.
A CAUTION:
With the wrong kind of fluid in your brake
system, your brakes
may not work well, or they
may not even work
at all. This could cause a
crash. Always use the proper brake fluid.
Using the wrong fluid can badly damage brake
system parts. For example, just
a few drops of
mineral-based oil, such as engine oil, in your
brake system can damage brake system
parts
so badly that they’ll have to be replaced. Don’t
let someone put in the wrong kind
of fluid.
NOTICE: (Continued) NOTICE:
(Continued)
If you spill brake fluid on your vehicle’s painted
surfaces, the paint finish can
be damaged. Be
carefbl not to spill brake
fluid on your vehicle.
If you do, wash it off immediately. See
“Appearance Care” in the Index.
Brake Wear
Your Cadillac has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that make
a
high-pitched warning sound when the brake pads are
worn
and new pads are needed. The sound may come and
go or be heard all the time your vehicle is moving (except
when you are pushing on the brake
pedal fmly).
A CAUTION:
The brake wear warning sound means that sooner
or later your brakes won’t work well. That could
lead to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
