Downloaded from www.Manualslib.com manuals search engine 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 (5 000 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
c”
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 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
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:
In heavy city traffic where the outside temperature
regularly reaches
90°F (32°C) or higher.
0 In hilly or mountainous terrain.
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.
6-17

Downloaded from www.Manualslib.com manuals search engine 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).
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 OF to 200 OF
(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 (lO"C), you may have to drive longer.
Checking the Fluid Level

Let the engine run at idle for three to five minutes. Then,
without shutting off the engine, follow these steps:
1. The black transaxle fluid cap is located next to the
radiator hose and below the air cleaner assembly
on
the driver's side of the engine. Remove the air
cleaner assembly so you can reach the transaxle fluid
cap, The assembly is attached to the vehicle
by two
fasteners. Simply lift up on the air cleaner assembly
to remove it. Find the transaxle fluid cap and turn it
counterclockwise to remove. Pull out the dipstick
and wipe it with

Don’t overfX We recommend you use only fluid
labeled DEXRON@-111, because fluid with that label
is made especially for your automatic transaxle.
Damage caused by fluid other than DEXRON-III is
not covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as
described under “How to Check.”
3. Check both sides of the dipstick, and read the lower
level. The fluidlevel must be
in the cross-hatched area.
4. If the fluid level is in the acceptable range, push the
dipstick back
in all the way.
5. Replace the air cleaner assembly.
How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind
of transaxle fluid to use. See “Recommended Fluids
and Lubricants”
in the Maintenance Schedule booklet.
If the fluid level is low, add only enough of the proper
fluid
to bring the level into the cross-hatched area on
the dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough fluid at the
dipstick hole
to bring it to the proper level. It doesn’t
take much fluid, generally less than a pint (0.5 L).
0 When the correct fluid level is obtained, push.the
dipstick back
in all‘ the way.
How to Reset Transaxle Fluid
Change Indicator
Your vehicle is equipped with a transaxle fluid change
indicator.
A CHANGE TRANS FLUID message will
display on the Driver Information Center (DIC) when
the powertrain computer determines that the transaxle
fluid needs to be changed. See your Maintenance
Schedule booklet for more information. When this
message appears, change the transaxle fluid and reset
the transaxle fluid life indicator as follows:
1. Turn the ignition on but do not start the engine.
2. Press and hold the OFF and rear defog buttons on the
climate control at the same time until the TRANS
FLUID
RESET message appears on the DIC.

Downloaded from www.Manualslib.com manuals search engine Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL rm (orange-colored, silicate-free) engine
coolant. This coolant is designed to remain
in your
vehicle
for 5 years or 100,000 miles (1 66 000 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:
0 Give freezing protection aown to -34°F (-37°C).
0 Give boiling protection up to 265 “F (129 O C).
0 Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights and gages work as they should.
NOTICE:
When adding coolant it is important that you use
DEX-COOL (orange-colored, silicate-free)
coolant meeting
GM Specification 6277M.
If dicated 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.)

Downloaded from www.Manualslib.com manuals search engine 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.
If you have to add coolant more than four times a year,
have 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.
