After the oil has been changed, display the OIL LIFE
LEFT message by pressing the INFORMATION (INFO)
button. Then press and hold the RESET (INFO RESET)
button until the display shows
“100.” This resets the
oil life index. The message will remain

next oil change
is needed. The percentage of oil life
remaining may be checked at any time by pressing
the
INFORMATION (INFO) button several times
until the
OIL LIFE LEFT message appears. For more
information on the Oil Life feature, see “Oil Life

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.

The air cleaner is located next to the windshield washer
fluid reservoir on the driver's side of the engine. Be sure
the engine has cooled before following these steps to
replace the air cleaner filter:
1. Disconnect the Intake
Air Temperature (IAT)
sensor from the base of
the air cleaner.
2. With a screwdnv&i,
loosen the air duct
clamp, which is
located at the mass airflow sensor end
of the air duct.
3. Disconnect the air duct from the mass axflow sensor.

located near the radiator hose (not shown) and the
other latch
is located next to the IAT sensor.
5. Pivot the air cleaner and air duct assembly toward
the front
of the vehicle. Remove the cover.
6. Take out the air cleaner filter and remove any loose debris that may be found laying in the air
cleaner base.
7. Install a new air filter element. See “Normal
Maintenance Replacement Parts” in the Index.

Downloaded from www.Manualslib.com manuals search engine Follow these steps to reinstall the air cleaner assembly:
1. Slide the air cleaner lid into the slots in the front
edge of the air cleaner base.
2. Pivot the air cleaner cover and the air duct assembly
downward. Make sure that both latches are secure
and fully engaged.
3. Reinstall the clean air duct over the mass airflow
sensor. Make sure that the duct is secure around the
entire outer edge of the sensor.
4. Tighten the air duct clamp.
5. Reconnect the IAT sensor.
Refer to the Maintenance Schedule to determine when to
replace the
air filter.
See “Scheduled Maintenance Services” in the
Maintenance Schedule booklet.
Operating the engine with the air cleaner off can
cause you or others
to be burned. The air cleaner
not only cleans the
air, it stops flames if the
engine backfires.
If it isn’t there, and the engine
backfires, you could be burned. Don’t drive with
it off, and be careful working on the engine with
the
air cleaner off.
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.

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:
0 In heavy city traffic where the outside temperature
regularly reaches
90°F (32°C) or higher.
0 In hilly or mountainous terrain.
0 When doing frequent trailer towing.
0 Uses such as found in taxi, police or delivery service.
Use such as limousine 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.
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.
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.
e While pulling a trailer.
6-18

Downloaded from www.Manualslib.com manuals search engine To get the right reading, the fluid should be at normal
operating temperature, which is 1
80 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
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).
0 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.
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. 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
one pint
(0.5 L). Don’t oveflll.
NOTICE:
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-In
is not covered by your new vehicle warranty.

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 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 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.
Engine Coolant
The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant is designed
to remain
in your vehicle for 5 years or 150,000 miles
(240 000 km) whichever occurs first, if you add only
DEX-COOL’ extended life 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.
J
A 50/50 mixture of water and DEX-COOL@
coolant will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 “F (129°C).
Protect against rust and corrosion.
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 only
DEX-COOL@ (silicate-free) coolant.
If coolant other than DEX-COOL@ 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. Damage caused by the use
of coolant other than DEX-COOL@ is not
covered by your new vehicle warranty.
