Have you recently changed brands of fuel? Oil Pressure Light
If so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index). Poor fuel quality will cause your
engine not to
run as efficiently as designed. You may
notice
this as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation on
acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
!
This will be detected by the system and cause the light
to
turn on.
If you,experience this condition, change the fuel brand
you use. It will require at least one full
tank of the
proper fuel to
turn the light off.
If none of the above steps .have made the light turn off,
have your dealer or qualified service center check the
vehicle.
Your dealer has the proper test equipment and
diagnostic tools to
fix any mechanical or electrical
problems that may have developed. This light tells
you
if there
could
be a problem with
your engine oil pressure.
The light goes on when you
turn your key to RUN or
STmT. It goes off once you start your engine. That’s a
check to
be sure the light works. If it doesn’t come on,
be .sure to have it fixed so it will be there to warn you if
something goes wrong.
When the light
comes on and stays on, it means that
oil isn’t flowing through your engine properly. You
could
be low on oil and you might have some other
system problem.

:. ..; .. .. .. '... ,
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.
Electronic Level Control
This feature keeps the rear of your vehicle level as the
load changes. It's automatic
-- you don't need to
adjust anything.

You will find an ENGINE COOLANT HOT-IDLE
ENGINE message
or a STOP ENGINE ENGINE
OVERHEATED message on the DIC. There is also an
engine temperature warning light
on the instrument
panel. See “Engine Temperature Warning Light” in the
Index.
Overheated Engine Protection Operating

Y
Should a low coolant condition exist and the message
STOP ENGINE
ENGINE OVERHEATED is displayed,
an overheat protection mode which alternates firing
groups
of four cylinders helps prevent engine damage.
This operating mode
allows your vehicle to be driven
to a safe place in
an emergency; you may drive up to
50 miles (80 km). Towing a trailer in the overheat
protection mode should be avoided.
I NOTICE:
After driving in the Overheated Engine
Protection Operating Mode,
to avoid engine
damage, allow the engine to cool before
attempting any repair. The engine oil may be
severely degraded. Change the
oil and reset the
oil life indicator. See “Engine Oil, When to
~ Change” in the Index.

A CAUTION:
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel
nuts
become loose after a time. The wheel could come
off and cause an accident. When you change a
wheel, remove any rust or dirt from the places
where the wheel attaches to the vehicle.
In an
emergency, you can use a cloth or a paper towel
to do this; but be sure to use a scraper or wire
brush later, if you need to, to get all the rust or
dirt off.
I A CAUTION:
~ ~~
Never use oil or grease on studs or nuts. If you
do, the nuts might come loose. Your wheel could
fall off, causing a serious accident.

nuts with the
rounded end of the

The oil fill cap is located
behind the radiator
on the
L
~ passenger’s side of the
~ engine. Turn the cap
1 counterclockwise to
remove.
Just fill it enough to
put the level somewhere in the
proper operating range. Push the dipstick all
the way
back in when
you’re through.
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:

As shown in the chart, SAE 1OW-30 is best for your
vehicle. However, you can use
SAE 5W-30 if it’s
going
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
Institute Certified
For Gasoline Engines
“Starburst” symbol. Failure
to use the
recommended
oil can result in engine damage
not covered by your warranty.
GM Goodwrench@ 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 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.
