Downloaded from www.Manualslib.com manuals search engine ENGINE OIL
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.
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.

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 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 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, 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

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. Refer to the Maintenance Schedule to determine
when
to change your fluid.

Downloaded from www.Manualslib.com manuals search engine 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.
NOTICE:
LI
Too much or too little fluid can damage your transaxle. Too
much can mean that some of the fluid could come out and fall l-
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.
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 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.

Downloaded from www.Manualslib.com manuals search engine How to Add Fluid
Refer to the Maintenance Schedule to determine what kind of transaxle
fluid to use.
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 (OSL).
Don’t ove@ZZ. 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 Information
Center when the powertrain computer determines that the transaxle fluid
-
needs to be changed or at each 100,000 miles (160 000 km) interval,
whichever occurs first. When this message appears, change the transaxle
fluid and reset the transaxle fluid life indicator as follows:
1. Turn the key ON but do not start the engine.
2. Press and hold the OFF and REAR DEFOG buttons on the climate
control simultaneously until the
TRANS FLUID RESET message
appears in the Information Center (between five and
20 seconds).

Downloaded from www.Manualslib.com manuals search engine To Check Brake Fluid
Remove the cap.
The fluid level must be to the maximum
fill line at the base of the neck as
shown. c_
When your brake fluid falls to a low level, your brake warning light will
come on. See “Brake System Warning Light”
in the Index.
Wat to Add
When you do need brake fluid, use only DOT-3 brake fluid -- such as Delco
Supreme
ll@ (GM Part No. 1052535). Use new brake fluid from a sealed
container only, and always clean the brake fluid reservoir cap before
removing
it.
NOTICE:
Don’t let someone put in the wrong kind of fluid. 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.
Brake fluid can damage paint, so be careful not to spill brake
fluid on your vehicle.
If you do, wash it off immediately. See
‘!Appearance Care” in the Index.
