Downloaded from www.Manualslib.com manuals search engine To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent deposits from forming in your engine and fuel
system, allowing your emission control system to
function properly. Therefore, you should not have to
add anything to the fuel. In addition, gasolines
containing oxygenates, such as ethers and ethanol,
and reformulated gasolines may be available in your
area to help clean the air. General Motors recommends
that you use these gasolines
if they comply with the
specifications described earlier.
Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard to
find. Never use leaded gasoline or any other fuel not
recommended in the previous text on
fuel. Costly repairs
caused by use of improper fuel 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
Vehicle Identification Number
(VIN).

Your vehicle was not designed for fuel that
contains methanol. Don’t use it. It can corrode
metal parts in your fuel system and also damage

Downloaded from www.Manualslib.com manuals search engine Filling Your Tank The cap is behind a hinged door on the driver’s side of
your vehicle.
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.
The fuel door release
button is located to the
left
of the steering wheel
next to the headlamp
knob
and on the Remote Keyless
Entry (RKE) transmitter. The button only
works in
PARK
(P) when the ignition
key is in any position.

Downloaded from www.Manualslib.com manuals search engine An alternate fuel door
release
is located inside of
the trunk on the left hand
side. Pull it
to release the
fuel door.
To take off the cap, turn it slowly to the left
(counterclockwise).
If you get gasoline on yourself 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.
Be careful not to spill gasoline. Clean gasoline from
painted surfaces as soon as possible. See “Cleaning the Outside of Your Cadillac” in the Index.
Hang the cap inside the fuel door while refueling.

(clockwise) until you hear
a clicking sound. Make sure
you fully install the cap.
NOTICE:
If you need a new cap, be sure to get the right
type. Your dealer can get one
for you. If you get
the wrong type, it may not
fit or have proper
venting, and your fuel tank and emissions system
might be damaged.
Checking Thiw~s Under the Hood
A CAU I ION: I

An electric fan under the hood can start up and
injure you even when the engine is not running.
Keep hands, clothing and tools away from any
underhood electric fan.
Things that burn can get on hot engine parts and
start a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber. You or others
could be burned. Be careful not to drop or spill
things that will burn onto a hot engine.

If you have the Driver Information Center (DIC), a
CHECK OIL LEVEL message will appear when the
engine oil is approximately
1 quart (1 L) low. If the
message is displayed, check the dipstick level and add
oil as needed. 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.
.. .......... The engine oil dipstick is
located behind the radiator on the driver’s side
of the
engine. The black handle
says ENGINE
OIL on it.
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 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 InstitGte certified
for gasoline engines.
You should also use the proper viscosity oil for your
vehicle, as shown in the following chart:

Downloaded from www.Manualslib.com manuals search engine Inflation -- Tire Pressure
“he Tire-Loading Information label, which is located on
the rear edge of the driver’s door, shows the correct
inflation pressures for your tires when they’re cold.
“Cold” means your vehicle has been sitting for at least
three hours or driven no more than
1 mile (1.6 km).
If you’ll be driving at speeds higher than 100 mph
(160
km/h) where it is legal, raise the cold inflation
pressure
of each tire to 35 psi (240 Pa). When you end
this very high-speed driving, reduce the cold inflation
pressures to those listed on the.Tire-Loading
Information label.
NOTICE:
Don’t let anyone tell you that underinflation or
overinflation is all right. It’s not.
If your tires
don’t have enough
air (underinflation), you can
get the following:
Too much flexing
Too much heat
Tire overloading
Bad wear
Bad handling
Bad fuel economy.
If your tires have too much air (overinflation),
you can get the following:
Unusual wear
Bad handling
Rough ride
Needless damage from road hazards.

Downloaded from www.Manualslib.com manuals search engine Underbody Maintenance
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
car washing system can do
this for you.
Chemical Paint Spotting
Some weather and atmospheric conditions can create
a chemical fallout. Airborne pollutants can fall upon
and attack painted surfaces on your vehicle. This
damage can take two forms: blotchy, ringlet-shaped
discolorations, and small irregular dark spots etched
into the paint surface.
Although
no defect in the paint job causes this, Cadillac
will repair, at no charge to the owner, the surfaces of
new vehicles damaged by this fallout condition within
12 months or 12,000 miles (20 000 km) of purchase,
whichever occurs first.
