Your new Cadillac comes with high-quality tires made
by a leading tire manufacturer.
If you ever have
questions about your tire warranty and where
to obtain
service, see your Cadillac Warranty booklet
for details.
U
Poorly maintained and improperly used tires
are dangerous.
0 Overloading your tires can cause
, overheating as a result of too much friction.
You could have an air-out and a serious
accident. See “Loading Your Vehicle” in
the Index.
0 Underinflated tires pose the same danger as
overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended pressure. Tire pressure should be checked
when your tires are cold.
CAUTION: (Continued)
0 Overinflated tires are more likely to be
cut, punctured or broken by a sudden
impact
-- such as when you hit a pothole.
Keep tires
at the recommended pressure.
0 Worn, old tires can cause accidents. If your
tread
is badly worn, or if your tires have
been damaged, replace them.

-- Tire Pressure’’ in this section

Downloaded from www.Manualslib.com manuals search engine 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 Pa).
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 rotated every 6,000 to 8,000 miles
(10 000 to 13 000 km). Any time you notice unusual
wear, 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. The
purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation is the most important. See “Scheduled
Maintenance Services” in the Maintenance Schedule
booklet for scheduled rotation intervals.
When rotating your tires, always use the correct
rotation pattern shown here.
Don’t include the compact spare tire in your
tire rotation.
6-42

Downloaded from www.Manualslib.com manuals search engine After the tires have been rotated, adjust the front
and rear inflation pressures as shown on the
Tire-Loading Information label. Make certain
that all wheel nuts are properly tightened. See
“Wheel Nut Torque”
in the Index.
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel nuts become loose
after a time. The wheel could come
off and cause
an accident. When you change a wheel, remove
any rust or dirt from places where the wheel
attaches to the vehicle. In an emergency, you can
use a cloth
or a paper towel to do this; but be
sure to use a scraper or wire brush later,
if you
need to, to get
all the rust or dirt off. (See
“Changing a Flat Tire” in the Index.) When It’s Time
for New Tires
One way to tell when it’s
time for new tires is to
check the treadwear
indicators, which will appear when your tires have
only 1/16 inch (1.6
mm) or
less of tread remaining.
You need a new tire
if any of the following statements
are true:
0 You can see the indicators at three or more places
0 You can see cord or fabric showing through the
around the tire.
tire’s rubber.
0 The tread or sidewall is cracked, cut or snagged deep
enough to show cord or fabric.
0 The tire has a bump, bulge or split.
0 The tire has a puncture, cut or other damage that
can’t be repaired well because
of the size or location
of the damage.

Windshield and Wiper Blades
If the windshield is not clear after using the windshield
washer, or if the wiper blade chatters when running, wax,
sap or other material may be on the blade or windshield.
Clean the outside of the windshield with
GM
Windshield Cleaner, Bon Ami@ Powder (non-scratching
glass cleaning powder), GM Part
No. 105001 1. The
windshield is clean if beads do not form when you rinse
it with water.
Grime from the windshield will stick to the wiper blades
and affect their performance. Clean the blade by wiping vigorously with a cloth soaked in full-strength windshield
washer solvent. Then rinse the blade with water.
Check the wiper blades and clean them as necessary;
replace worn blades.
Weatherstrips
Silicone grease on weatherstrips will make them
last longer, seal better, and not stick or squeak.
Apply silicone grease with a clean cloth at least
every six months. During very cold, damp weather
more frequent application may be required. (See
“Recommended Fluids and Lubricants”
in the
Maintenance Schedule booklet.)
Cleaning the Outside of Your
Cadillac
The paint finish on your vehicle provides beauty, depth
of color, gloss retention and durability.
Washing Your Vehicle
The best way to preserve your vehicle’s finish is to keep
it clean by washing it often with lukewarm or cold water.
Don’t wash your vehicle in the direct rays of the sun.
Don’t use strong soaps or chemical detergents. Use
liquid hand, dish or car washing (mild detergent) soaps.
Don’t use cleaning agents that are petroleum based, or
that contain acid or abrasives. All cleaning agents
should be flushed promptly and not allowed to dry on
the surface, or they could stain. Dry the finish with a
soft, clean chamois or an all-cotton towel to avoid surface scratches and water spotting.
High pressure car washes may cause water to enter
your vehicle.
Cleaning Exterior LampsLenses
Use lukewarm or cold water, a soft cloth and a liquid
hand, dish
or car washing (mild detergent) soap to clean
exterior lamps and lenses. Follow instructions under
“Washing Your Vehicle.”

Add-on Electrical Equipment
NOTICE:
Don’t add anything electrical to your Cadillac
unless you check with your dealer first. Some
electrical equipment can damage your vehicle
and
the damage wouldn’t be covered by your warranty.
Some add-on electrical equipment can keep other
components
from working as they should.
Your vehicle has an air bag system. Before attempting to
add anything electrical to your Cadillac, see “Servicing
Your Air Bag-Equipped Cadillac” in the Index.
Headlamp Wiring
The headlamp wiring has an individual fuse which is
powered by a MaxiFuse@. An electrical overload will
cause the lamps to
go on and off, or in some cases to
remain off. If this happens, have the headlamp wiring
checked right away.
MaxiFuse
is a registered trademark of Little
Fuse Incorporated.
Windshield Wiper Fuses
The windshield wiper motor is powered by a MaxiFuse.
If
the motor overheats due to heavy snow, etc., the
wipers will stop until the motor cools. If the overload
is caused by some electrical problem, be
sure to have
it fixed.
Power Windows and Other Power Options
Circuit breakers protect the power windows and other
power accessories. When the current load is too heavy,
the circuit breaker opens and closes, protecting the
circuit until the problem is fixed or goes away.
