A CAUTION:
You can be injured if you try to do service work on a vehicle
without knowing enough about it.
Be sure you have sufficient knowledge, experience, and the
proper replacement parts and tools before you attempt any
vehicle maintenance task.
Be sure to use the proper nuts, bolts and other fasteners.
“English” and “metric” fasteners can be easily confused.
If
you use the wrong fasteners, parts can later break or fall off.
You could be hurt.
FUEL
Use premium unleaded gasoline rated at 91 octane or higher. It should
meet specifications ASTM
D4814 in the US. and CGSB 3.5-92 in
Canada. These fuels should have the proper additives,
so you should not
have to add anything to the fuel.
In the
U.S. and Canada, it’s easy to be sure you get the right kind of
gasoline (unleaded). You’ll see “UNLEADED” right on the pump. And
only unleaded nozzles will fit into your vehicle’s filler neck.
Be sure the posted octane is at least 91.
If the octane is less than 91, you
may get a heavy knocking noise when you drive.
(In an emergency, you
may be able
to use lower octane -- as low as 87 -- if heavy knocking does
not occur.)
If you’re using 91 or higher octane unleaded gas and you still
get heavy knocking, your engine needs service.

Downloaded from www.Manualslib.com manuals search engine What about gasoline with blending materials that contain oxygen, such as
MTBE or alcohol?
MTBE is “methyl tertiary-butyl ether.” Fuel that is
no more than 15%
MTBE is fine for your car.
Ethanol is ethyl or grain alcohol. Properly-blended fuel that is no more
than
10% ethanol is fine for your car.
Methanol is methyl or wood alcohol.
Gasolines for Cleaner
Air
Your use of gasoline with detergent additives will help prevent deposits
from forming in your engine and fuel system. That helps keep
your
engine in tune and your emission control system working properly. It’s
good for your vehicle, and you’ll be doing your part for cleaner air.
Many gasolines are
now blended with materials called oxygenates.
General Motors recommends that you use gasolines with these blending
materials, such as
MTBE and ethanol. By doing so, you can help clean
the air, especially in those parts of the country that have high carbon
monoxide levels.
In addition, some gasoline suppliers are now producing reformulated
gasolines. These gasolines are specially designed to reduce vehicle
emissions. General Motors recommends that you use reformulated
gasoline.
By doing so, you can help clean the air, especially in those parts
of the country that have high ozone levels.
You should ask your service station operators if their gasolines contain
detergents and oxygenates, and if they have been reformulated to reduce
vehicle emissions.

If you plan 6n driving in another country outside the U.S. or Canada,
unleaded fuel may be hard to find.
Do not use leaded gasoline. If you use
even one tankful, your emission controls won’t
work well or at all. With
continuous use, spark plugs can get fouled, the exhaust system can
corrode, and your engine
oil can deteriorate quickly. Your vehicle’s
oxygen sensor
will be damaged. All of that means costly repairs that
wouldn’t be covered by your warranty.
To check on fuel availability, ask an auto club, or contact a major oil
company that does business in the country where you’ll be driving.
You can also write us at the following address for advice. Just tell
us
where you’re going and give your Vehicle Identification Number (VIN).

FILLING YOUR TANK

Downloaded from www.Manualslib.com manuals search engine I
A CAUTION:
Gasoline vapor is highly flammable. It burns violently, and that
can cause very bad injuries. Don't smoke if you're near gasoline
or refueling your vehicle. Keep sparks, flames, and smoking
materials away from gasoline.
If you're refueling your tank using a hydrocarbon recovery nozzle, the
fuel pump may shut off before the
fuel capacity of your tank reaches full.
This
is a normal condition. If you slow the flow of fuel going into the
tank, it is more likely to fill to capacity without shutting off.
The cap is behind a hinged door
on the left side of your vehicle. Pushin
on the front edge
of the door to open.

release lever located
on the left side in the
trunk. Pull the lever
toward the rear
of your
vehicle to release the
fuel door.
To take off the cap, turn it slowly to the left (counterclockwise).
While refueling, hang the cap inside the fuel door.
A CAUTION:
If you get gasoline on you and then something ignites it, you
could be badly burned. Gasoline can spray out on you if you
open the fuel filler cap too quickly. This spray can happen if
your tank is nearly full, and is more likely in hot weather. Open
the fuel filler cap slowly and wait for any “hiss” noise to stop.
Then unscrew the cap all the way.
When you put the cap back on, turn it
to the right until you hear a
clicking noise.

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.

Downloaded from www.Manualslib.com manuals search engine SAE 1OW-30
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.

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.

Downloaded from www.Manualslib.com manuals search engine How To Reset the Oil Life Indicator: After the oil has been changed,
press and hold the
“RANGE” and “RESET” buttons between 5 and 60
seconds. 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 for 5 seconds it did not reset. You will need
to reset the system again. The percentage
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.

The other label is the Certification label, found on the rear edge of the
driver’s door. It tells you the gross weight capacity
of your vehicle, called
the GVWR (Gross Vehicle Weight Rating). The GVWR includes the
weight
of the vehicle, all occupants, fuel and cargo. Never exceed the
GVWR for your vehicle, or the Gross Axle Weight Rating (GAWR) for
either the front or rear axle.
And, if you do have a heavy load,
you should spread it out. Don’t carry

A CAUTION:
I- Do not load your vehicle any heavier than the GVWR or the
