1997 CADILLAC DEVILLE gas type

Downloaded from www.Manualslib.com manuals search engine Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around it. This may cause wind noise
and affect windshield washer performance. Check with
your Cadillac dealer before adding equipment to the
outside of your vehicle.
Fuel
Use premium unleaded gasoline rated at 91 octane
or higher. At a minimum,
it should meet specifications
ASTM D4814
in the United States and CGSB 3.5-M93
in Canada. Improved gasoline specifications have been
developed by the American Automobile Manufacturers
Association (AAMA) for better vehicle performance
and engine protection. Gasolines meeting the AAMA
specification could provide improved driveability
and emission control system protection compared to
other gasolines.
Be sure the posted octane for premium 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 a lower octane
-- as low as 87 -- if
heavy knocking does not occur.) If you’re using 91 or
higher octane unleaded gasoline and you hear
heavy knocking, your engine needs service. If
your vehicle is certified to meet California Emission
Standards (indicated on the underhood tune-up label),
it is designed to operate on fuels that meet California
specifications.
If such fuels are not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily
on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp on
your instrument panel may turn on and/or your vehicle
may fail a smog-check test. If this occurs, return to your
authorized Cadillac dealer for diagnosis to determine the
cause of failure.
In the event it is determined that the
cause
of the condition is the type of fuels used, repairs
may not be covered by your warranty.
Some gasolines that are not reformulated for low
emissions contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl (MMT);
ask your service station operator whether or not this fuel
contains
MMT. General Motors does not recommend
the use of such gasolines. If fuels containing MMT
are used, spark plug life may be reduced and your
emission control system performance may be affected.
The malfunction indicator lamp on your instrument
panel may turn on. If this occurs, return to your
authorized Cadillac dealer for service.

(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
r- - 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.

NOTICE:
Use tire chains only where legal and only when
you must. Use only
SAE Class “S” type chains
that are the proper size for your tires. Install
them on the front tires and tighten them
as
tightly as possible with the ends securely
fastened. Drive slowly and follow the chain
manufacturer’s instructions.
If you can hear the
chains contacting
your vehicle, stop and retighten
them.
If the contact continues, slow down until it
stops. Driving too fast
or spinning the wheels
with chains on will damage your vehicle.
Appearance Care
Remember, cleaning products can be hazardous. Some
are toxic. Others can burst into flames if you strike a
match or get them on a hot part
of the vehicle. Some are
dangerous
if you breathe their fumes in a closed space.
When you use anything from
a container to clean your
Cadillac, be sure to follow
the manufacturer’s warnings and instructions.
And always open your doors or
windows when you’re cleaning the inside.
Never use these to clean your vehicle:
0 Gasoline
Benzene
0 Naphtha
0 Carbon Tetrachloride
Acetone
Paint Thinner
Turpentine
0 Lacquer Thinner
0 Nail Polish Remover
They can all be hazardous
-- some more than
others
-- and they can all damage your vehicle, too.
Don’t use any
of these unless this manual says you can.
In many uses, these will damage your vehicle:
Alcohol
0 Laundry Soap
Bleach
0 Reducing Agents
