Oil Life Indicator
Your Cadillac has an Oil Life Indicator feature. This tells you when you
need to change your engine oil.
It’s based upon the engine oil
temperatures and your driving patterns.

cl
Press and hold the
Range and Fuel Used
buttons to display the
oil life percentage.
You’ll
see how much oil life you have left, as a percentage. So if you see
“94” for example, that means that the way you’re driving your vehicle,
94%
of your current oil life is still left.
The
“CHANGE OIL SOON” light will come on for a few seconds as a
bulb check when you start your engine. The light will also come on for
20
seconds following engine start-up when either the oil life percentage is
less the
10% or 7,500 miles (12500 km) have been driven. The system
probably will say to change the oil between
3000 miles (5000 km) and
7500 miles (12500 km), but it may even say to change it before 3000 miles
under severe conditions. It all depends on your driving patterns.
(If it
doesn’t,
or if it doesn’t even light up, then something is wrong. You will
need to have it serviced.)
There
are two things the system won’t do: It can’t sense heavy dust in the
places where you drive.
If you drive in a dusty area, you should change
your oil every
3000 miles (5000 km) or 3 months (whichever comes first),
unless the “CHANGE
OIL SOON” light comes on sooner.
It doesn’t check how much oil you have
so you will still have to check for
that.
To check it, see the Index under “Engine Oil.”
When You’ve Changed the Oil
When new oil is put in, you’ll need to reset your system. To do that, press
and hold the “Range” and “Reset” buttons between
5 and 60 seconds.

Downloaded from www.Manualslib.com manuals search engine Once the buttons are released the “CHANGE OIL SOON” light will
flash 4 times to indicate it has reset to
100.
If the “CHANGE OIL SOON” light comes on and stays on for 5 seconds,
it did not reset. You’ll need to reset the system again.
SPEED SENSITIVE SUSPENSION
(SSS SYSTEM)
The Speed Sensitive Suspension System (SSS) automatically controls the
firmness of your Cadillac’s ride. The vehicle is controlled by an actuator
in each of the four struts to increase ride firmness depending on vehicle
speed and other driving conditions. There are three dampening modes:
COMFORT, NORMAL, and
FIRM. As the vehicle speed increases, the
firmness of the suspension increases. The system is in COMFORT for
speeds less than
28 mph, NORMAL for speeds between 28 and 65 mph,
and FIRM for speeds greater than
65 mph. The system also stiffens
damping during hard acceleration, braking and cornering ,for increased
control.
The SSS controller is a computer used to control and monitor the system.
The computer receives speed, acceleration and determines optimum
mode strut valving (or suspension stiffness) for your current operating
conditions. The computer also receives feedback from the struts to
determine proper system operation.
If the computer receives an incorrect
feedback from the system, an error code
will be set in memory and a
“SERVICE
SSS” light will come on and stay on until the problem is
corrected.
If this light should appear, have your vehicle serviced at your
earliest convenience.
SPEED SENSITm STEERING
This system varies the amount of steering effort proportionate to your
vehicle speed. Steering is easier at a lower speed for increased
maneuverability and parking ease. As your vehicle speed increases, the
steering effort is also increased proportionately. At highway speeds the
amount
of steering effort is greatly increased to provide a manual like
steering
feel for maximum control and enhanced vehicle stability.

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 vehicte. In a emergency, you could use a cloth or
a paper towel to do this; but be sure to use a scraper or wipe
brush later, if you need to, to get all the rust'or dirt off.
-I
Remove any rust or dirt from the wheel bolts, mounting surfaces or spare
wheel. Place the spare on the wheel mounting surface.
I .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.

As shown in the viscosity 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, below
O°F
(-18”C), 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 1OW-40 or SAE
20W-50.
Energy Conserving I1
Oils with these words on the container will help you save fuel.
This doughnut-shaped logo (symbol) is used on most
oil containers to
help you select the correct
oil.
You should look for this on the oil container, and use only those oils that
display the logo.

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 vehicle is equipped with an Engine Oil
Life Index (EOLI) feature. Oil change intervals are determined by the
EOLI and will usually fall at, or between, the two recommended
alternative intervals of 3,000 miles
(5,000 kilometers) and 7,500 miles
(12,500 kilometers), but could be shorter than 3,000 miles (5,000
kilometers) under some very severe driving conditions shown in Schedule
I. The system will also indicate the need for an oil change if 7,500 miles
(12,500 kilometers) has been driven.
Engine oil life remaining is displayed through the Fuel Data center and as
a
“CHANGE OIL SOON” light. The Fuel Data center display includes a
number between
0 and 100. This is the percentage of oil life
REMAINING based on driving conditions and mileage driven since the
last time the oil life indicator was reset.
The EOLI will not detect excessively dusty conditions or engine
malfunctions which may effect the
oil. If you drive in dusty areas, change
the engine
oil after every 3,000 miles (5,000 kilometers) or 3 months
(whichever comes first), unless instructed to
do so sooner by the EOLI.

of oil life remaining may be
checked at any time by pressing the
“RANGE” and “FUEL USED” on
the Fuel Data center.
Engine Block Heater: An engine block heater can be a big help if you
have to park outside
in very cold weather, O°F (-18OC) or colder. If your
vehicle has this option, see “Engine Block Heater” in the Index.
What to Do with Used Oil:
’
A CAUTION:
Used engine oil contains things that have caused skin cancer in
laboratory animals. 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.
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 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.

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. 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
could get a false reading on the dipstick.
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).
0 At high speed for quite a while.
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
(10" C), you may have to drive longer.
