P
c
:. ..; .. .. .. '... ,
This feature lets you know when to change the engine
oil. It's based on the engine oil temperatures and
your driving patterns.
To see the display, press the
INFORMATION button several times until
XX OIL
LIFE LEFT appears. If you see 99% OIL LIFE LEFT,
99% of your current oil life remains.
The DIC may display a
CHECK OIL LEVEL message.
Always keep a written record of the mileage and date
when you changed your oil. For more information, see
the Cadillac Maintenance Schedule booklet.
If you see
CHECK OIL LEVEL, it means that you have less
than 10% of the oil life left and you'should consider
changing your engine oil. If you see
CHANGE
ENGINE OIL, it means the oil life is gone and you
should change the oil right away.
The system should indicate changing the oil between
3,000 miles (5 000 km) and 7,500 miles (12 500 km).
It may indicate changing the oil before 3,000 miles
(5 000 km) depending on your driving habits. If the
vehicle has been driven
7,500 miles (12 500 km) it
will indicate to change the oil.
If you drive in a dusty
area, you should change your oil every
3,000 miles
(5 000 km) or three months (whichever comes first)
unless the display indicates changing
it sooner. The
system doesn't check
how much oil you have, so
you'll still have to check for that. To see how, see
"Engine Oil" in
the Index.
When new oil is added, you'll need to reset the system.
To reset, display the Oil Life Indicator by pressing the
INFORMATION button. Then press and hold the RESET
button until the display shows 100 OIL LIFE LEFT.

adjust anything.

Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer

engine oil, belt, cooling system and brake adjustment.
Each
of these is covered in this manual, and the Index
will help you find them quickly.
If you’re trailering, it’s
a good idea to review these sections before you start
your trip.

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.

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.

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.

When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
you hear an unusual noise.
A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
How To Check Power Steering Fluid
When the engine compartment is cool, unscrew the cap
and wipe the dipstick with a clean rag. Replace the cap
and completely tighten it. Then remove the cap again
and look at the fluid level on the dipstick.
The level should be at the
FULL COLD mark. If
necessary, add only enough fluid to bring the level up to
the mark.
What to Use
Refer to the Maintenance Schedule to determine what
kind of fluid to use. See “Recommended Fluids and
Lubricants” in the Maintenance Schedule booklet.
Always use the proper fluid. Failure to use the proper
fluid can cause leaks and damage hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before use. If you will be
operating your vehicle
in an area where the temperature
may fall below freezing, use a fluid that has sufficient
protection against freezing.
