You should also use the proper viscosity oil for your vehicle, as shown in
the following chart:

LABELS
IF NEITHER SAE 5W-30 NOR SAE 1OW-30
GRADE OILS ARE AVAILABLE, SAE 30 GRADE MAY BE USED AT TEMPERATURES
ABOVE 40 DEGREES F (4 DEGREES C).
ANY OTHER GRADE OIL NOT RECOMMENDED DO NOT USE SAE 1OW-40, SAE 20W-50 OR
As shown in the chart, SAE 5W-30 is best for your vehicle. However, you
can use
SAE 1OW-30 if it’s going to be 0°F (-18OC) or above. These
numbers on an oil container show its viscosity, or thickness.
Do not use
other viscosity oils, such as
SAE 1OW-40 or SAE 20W-50.
If you cannot find oils with the new “starburst” symbol on the front of the
container, you should look for and use oils containing the following three
things:

0 SH or SG
“SH”or “SG” must be on the oil container, either by itself or
combined with other quality designations, such as “SWCD,”
“SH,SG,CD,” etc. These letters show American Petroleum Institute
(MI) levels of quality.
SAE 5W-30

Oils with these words on the container will help you save fuel.
These three things are usually included in a doughnut shaped logo
(symbol) on most containers. If you cannot find oils with the “starburst”
symbol, you should look for oils with the doughnut shaped symbol,
containing the three things noted above.
I NOTICE:
If you use oils that do not have either the “starburst” symbol or
an
API SH designation, you can cause engine damage not
covered by your warranty.
GM Goodwrench@ oil (in Canada, GM Engine Oil) meets all the
requirements for your vehicle.

Engine Oil Additives
Don’t add anything to your oil. Your Cadillac dealer is ready to advise if
you think something should be added.
When 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 Oil Soon” light 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, you’ll need to reset your system. To
do that, turn the ignition switch to the “ON” position with the engine
stopped. Fully depress and release the accelerator pedal
3 times within
5 seconds.
If the “CHANGE OIC’ light comes on and stays on for 5 seconds, it did
not reset. You’ll need to reset the system again.
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.
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.
AIR CLEANER
c- c
See “Scheduled Maintenance Services” in the Index. Refer
to the
Maintenance Schedule
to determine when to
replace the air filter.

-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. I
I AUTOAUTIC .TRANsIMISSION FLUID
‘When to Check and Change
A good time to check your automatic transmission 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 .a Cadillac dealership Service Department.
If you do it yourself, be sure to follow all the instructions here, or you
cou.ld get a false reading on the dipstick.
I I Too NOTICE: much or too little fluidcan damage your. transmission. Too
much can mean that some of the fluid could come out and fall
on hot engine parts or exhaust system, starting
a fire. Be sure to
get an accurate reading
if you check your transmission fluid. i
I
Wait at least 30 minutes before checking the transmission fluid level if
you
have been driving:
When outside temperatures are above 90°F (32OC).

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).
To check transmission fluid hot: 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 (10" C), drive the vehicle in "D" (3rd
Gear) until the engine temperature gage moves and then remains steady
for ten minutes. Then follow the hot check procedures.
To check transmission fluid cold: A cold check is made after the vehicle
has been sitting for eight hours or more with the engine
off and is used
only as a reference. Let the engine run at idle for five minutes
if outside
temperatures are
50 " F (10 " C) or more. If it's colder than 50 " F (10 " C),
you may have to idle the engine longer. Should the fluid level be low
during a cold checkj you must perform a hot check before adding fluid.
This will give you a more accurate reading
of the fluid level.
To check thefluid hot or cold

How to Add Fluid
Refer to the Maintenance Schedule to determine what kind of
transmission fluid to use. See “Recommended Fluids and Lubricants” in
the Index.
If the fluid level is low, add only enough of the proper fluid to bring the
level up to the COLD area for a cold check
or the HOT area for a hot
check. It doesn’t take much fluid, generally less than a int.
Don’t overfill.
We recommend you use only fluid labeled DEXRON -111 or
DEXRON@-IIE, because fluids with that label are made especially for
your automatic transmission. Damage caused by fluid other than
DEXRON@-I11 or DEXRON@-IIE is not covered by your new vehicle
warranty. 8

When to Check and Change Lubricant
Refer to the Maintenance Schedule to determine how often to check the
lubricant and when to change it. See “Periodic Maintenance Inspections”
in the Index.
How to Check Lubricant
If the level is below the bottom of the filler plug hole, you’ll need to add
some lubricant. Add enough lubricant to raise the
level to the bottom of
the filler plug hole.
265

What to Use
Standard Differential
Use Axle Lubricant (GM Part No. 1052271) or SAE 8OW-90 GL-5 gear
lubricant.
ENGINE COOLANT
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.
The proper coolant for your Cadillac
will:
Give freezing protection down to -34 F (-37 C).
Give boiling protection up to 262 F (128 C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
I Let the warning lights work as they should.
1 What to Use
Use a mixture of one-half clean water (preferably distilled) and one-half
antifreeze that meets “GM Specification 1825-M,” which won’t damage
aluminum parts.
You can also use a recycled coolant conforming to GM
Specification 1825-M with a complete coolant flush and refill. Use GM
Engine Coolant Supplement (sealer) with any complete coolant change.
If you use this mixture, you don’t need to add anything else.
