In Canada, some gasolines contain an octane-enhancing
additive called
“T. If you use such fuels, your
emission control system performance may deteriorate
and
the malfunction indicator lamp on your instrument
panel may turn on. If this happens, return
to your
authorized Cadillac dealer for service.
To provide cleaner air, all gasolines 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.
NOTICE:
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
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.
Fuels in Foreign Countrics
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
advice. Just tell us where you’re going and give your
Vehicle Identification Number (VIN).

f
i
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. The button
only works in PARK (P)
when the ignition key is in
any position.
An alternate fuel door
release
is located inside of
the trunk on the left hand
side. Pull it to release
the
fuel door.

A CAUTION:
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.
Hang the cap inside the fuel door while refueling.
TO take off the cap, turn it slowly to the left
(counterclockwise). 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.

Downloaded from www.Manualslib.com manuals search engine When you put the cap back on, turn it to the right until
you hear at least three clicks. 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 Things Under the Hood
A CAUTION:
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.
A CAUTION:
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.

A CHECK OIL LEVEL message will appear when
the engine oil
is approximately a quart 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.

DO NOT USE SAL 2OW-50 OR ANY OTHER GRADE OIL NOT RECOMMENDED
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.

?ressures to those listed on the Tire-Loading [nformation 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
Needless damage from road hazards.
i Rough ride
When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It should be
at
60 psi (420 Wa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can’t tell
if your tires are properly inflated
simply by
looking at them. Radial tires may look
properly inflated even when they’re underinflated.
Be sure to put the valve caps back on the valve stems.
They help prevent leaks by keeping out dirt and moisture.
Tire Inspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles
(10 OOO to 13 000 km) for any signs of unusual wear.
If unusual wear is present, rotate your tires as soon
as
possible and check wheel alignment. Also check for
damaged tires
or wheels. See “When It’s Time for New
Tires” and “Wheel Replacement” later
in this section for
more information.

Finish Damage
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.
Underbody Maintenance c-
rc
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,OOO miles (20 000 km) of purchase,
whichever occurs first.
