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:

to be colder than 60°F (16°C) before your
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.
6-17
c

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).
At high speed for quite a while.
0 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 abut 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.

Park your vehicle on a level place. Keep the engine
running.
With the parking brake applied, place the shift Lever
in
PARK (P).
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 PARK (P).
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 a clean rag or paper towel.
then pull it back out again.
2. Push it back in all the way, wait three seconds and
6-18

Downloaded from www.Manualslib.com manuals search engine 3. Check both sides of the dipstick, and read the lower
level. The fluid level 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).
Don’t oveflll. 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-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 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.
