Downloaded from www.Manualslib.com manuals search engine Service and Appearance Care
Here you will find information about the care of your
Cadillac. This section begins with service and fuel
information, and then it shows how to check important
fluid and lubricant levels. There is also technical
information about your vehicle, and a part devoted to
its appearance care.
Service
Your Cadillac dealer knows your vehicle best and wants
you to be happy with it. We hope you’ll go to your
dealer for all your service needs. You’ll get genuine GM
parts and GM-trained and supported service people. We
hope you’ll want to keep your GM vehicle all
GM.
Genuine GM parts have one of these marks:
Doing Your Own Service Work
If you want to do some of your own service work, you’ll
want to get the proper Cadillac Service Manual. It tells
you much more about how to service your Cadillac than
this manual can. To order the proper service manual, see
“Service and Owner Publications” in the Index.

Downloaded from www.Manualslib.com manuals search engine Your vehicle has an air bag system. Before attempting to
do your own service work, see “Servicing Your Air
Bag-Equipped Cadillac” in the Index.
You should keep a record with all parts receipts and list
the mileage and the date of any service work you
perform. See “Maintenance Record” in the Index.
You can be injured and your vehicle could be
damaged
if you try to do service work on a
vehicle without knowing enough about it.
0 Be sure you have sufficient knowledge,
experience, and the proper replacement
parts and tools before you attempt any
vehicle maintenance task.
0 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 regular unleaded gasoline rated at 87 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) €or 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 is at least 87.
If the octane is
less than 87, you may get a heavy knocking noise when
you drive. If it’s bad enough, it can damage your engine.
If you’re using fuel rated at 87 octane or higher and you
still hear heavy knocking, your engine needs service.
But don’t
worry if you hear a little pinging noise when
you’re accelerating or driving up a hill. That’s normal,
and you don’t have to buy a higher octane fuel to get rid
of pinging. It’s the heavy, constant knock that means
you have a problem.

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.

Filling Your Tank
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.
Your vehicle has a locking fuel filler door.
The cap is behind the license plate. Pull down on the top
of the license plate bracket door
to open.
6-4

Downloaded from www.Manualslib.com manuals search engine The filler door is locked and unlocked every time you
use the power door locks.
If pressing the power lock
control doesn’t unlock or lock the fuel filler door, you
can use the manual lock release lever in
the trunk, if
your vehicle is
so equipped. Move the lever to the left to
unlock the fuel filler door.
To take
off the cap, turn it slowly to the left
(counterclockwise).
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.
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.
The diagnostic system can determine if the fuel
cap has been left off or improperly installed. This would
allow fuel to evaporate into the atmosphere. See
“Malfunction Indicator Lamp” in the Index.
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 CkmON’:
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.

Downloaded from www.Manualslib.com manuals search engine Inflation -- Tire Pressure
The Tire-Loading Information label, which is located on
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).
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
0 Too much heat
0 Tire overloading
Bad wear
0 Bad handling
0 Bad fuel economy.
NOTICE: (Continued) NOTICE: (Continued)
If your
tires have too much air (overinflation),
you can get the following:
Unusual wear
0 Bad handling
0 Rough ride
0 Needless damage from road hazards.
When to Check
Check your tires once a month or more. Also, check the
tire pressure
of the spare tire.
If you have a compact spare tire, it should be at
60 psi
(420 Ea).
HQW 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.

Tires
To clean your tires, use a stiff brush with a tire cleaner.
NOTICE:
When applying a tire dressing always take care to
wipe
off any overspray or splash from all painted
surfaces on the body or wheels
of the vehicle.
Petroleum-based products may damage the
paint finish.
Sheet Metal Damage
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.
Finish Damage
Any stone chps, 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
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.
