below the
bottom of the filler plug hole.

Windshield Wiper Blade Replacement
Windshield wiper blades should be inspected at least
twice a year for wear or cracking.
See
Normal Maintenance Replacement Parts on
page 5-94 for the proper type of replacement blade.
Notice: Use care when removing or installing
a blade assembly. Accidental bumping can cause
the arm
to fall back and strike the windshield.
1. To remove the old wiper blades, lift the wiper arm
until it locks into a vertical position.

Tires
Your new vehicle 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 Oldsmobile Warranty booklet for details.
I
Poorly maintained and imprope -
are dangerous.
-
used tires
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.
CAUTION: (Continued)
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.
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.
Worn, old tires can cause accidents. If
your tread is badly worn, or if your tires have been damaged, replace them.
5-52

Inflation -- Tire Pressure
The Certificationnire label, which is on the driver’s door
edge, above the door latch, 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:
0 Too much flexing
Too much heat
0 Tire overloading
Bad wear
0 Bad handling
0 Bad fuel economy
If your tires have too much air (overinflation), you
can get the following:
0 Unusual wear
0 Bad handling
0 Rough ride
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.
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 7,500 miles (12 500 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 Is Time
for New Tires
on page 5-55 and Wheel Replacement
on page 5-58 for more information.
Make sure the spare tire
is stored securely. Push, pull,
and then try
to rotate or turn the tire. If it moves,
use the wheel wrench to tighten the cable. See
Changing a Flat Tire on page 5-62.
