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.

SAE VISCOSITY GRADE OIL FOR THE EXPECTED TEMPERATURL RANGE.

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.

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.

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
more than
127 pounds (58 kilograms) in your trunk.

A CAUTION:
I- Do not load your vehicle any heavier than the GVWR or the
maximum front and rear
GAWRs. If you do, parts on your
vehicle can break, or it can change the way your vehicle handles.
These could
cause you to lose control. Also, overloading can
shorten the life of your vehicle.

If your vehicle is damaged and requires sheet metal repair or
replacement, make sure the body repair shop applies anti-corrosion
material to the parts repaired
or replaced to restore corrosion protection.
FOREIGN MATEML
Calcium chloride and other salts, ice melting agents, road oil and tar, tree
sap, bird droppings, chemicals from industrial chimneys, and other
foreign matter can damage your vehicle’s finish
if they remain on painted
surfaces. Use cleaners that are marked safe
for painted surfaces for these
stains.
FINISH DA2MAGE
Any stone chips, fractures or deep scratches in the finish should be
repaired right away. Bare metal will corrode quickly and may develop
into a major repair expense.
Minor chips and scratches can be repaired with touch-up materials
available from your dealer or other service outlets. Larger areas of finish
damage can be corrected in your dealer’s body and paint shop.
UNDERBODYMMNTENNrE
Chemicals used for ice and snow removal and dust control can collect on
the underbody. If these are not removed, accelerated corrosion (rust) can
occur
on the underbody parts such as fuel lines, frame, floor pan, and
exhaust system even though they have corrosion protection.
At least
every spring, flush these materials from the underbody with plain
water. Clean any areas where mud and other debris can collect. Dirt
packed in closed areas of the frame should be loosened before being
flushed. Your dealer or an underbody vehicle washing system can do this
for you.
