Windshield Wiper Blade Replacement
Windshield wiper blades should be inspected at least
twice a year for wear or cracking. See ªWiper Blade
Checkº in the Index for more information.
Replacement blades come in different types and are
removed in different ways.
To replace the wiper blade assembly:
1. Position the wipers on the windshield in the ªmidº
wipe position.
2. Lift the windshield wiper arm away from the
windshield. The windshield wiper does not have a
locking upright position feature.

6-46
3. Push the tab on the wiper blade assembly and pull
the assembly down enough to release it from the
ªUº hooked end of the wiper arm. Slide the
assembly away from the arm.
4. Replace the blade.
5. To reinstall the wiper blade assembly, slide it over
the wiper arm to engage the ªUº hooked end on the
wiper blade assembly. Pull up on the assembly to
lock it into place.
For the correct windshield wiper blade replacement
length and type, see ªNormal Maintenance Replacement
Partsº in the Index.
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 Buick Warranty booklet for details.
CAUTION:
Poorly maintained and improperly used tires
are dangerous.

Overloading your tires can cause
overheating as a result of too much friction.
You could have an air
-out and a serious
accident. See ªLoading Your Vehicleº in
the Index.

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)

6-47
CAUTION: (Continued)

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.
Inflation -- Tire Pressure
The Tire-Loading Information label, which is located on
the rear edge of the driver's door, shows the correct
inflation pressures for your tires when they're cold.
ªColdº 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

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

Rough ride

Needless damage from road hazards.

6-48
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 kPa).
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.
Check Tire Pressure System (If Equipped)
The check tire pressure system can alert you to a large
change in the pressure of one tire. The system won't
alert you before you drive that a tire is low or flat.
You must begin driving before the system will
work properly.The TIRE PRESSURE LOW message will appear on
the Driver Information Center (DIC) if pressure
difference (low pressure) is detected in one tire.
The check tire pressure system may not alert you if:

more than one tire is low,

the vehicle is moving faster than 65 mph (105 km/h),

the system is not yet calibrated,

the tire treadwear is uneven,

the compact spare tire is installed,

tire chains are being used, or

the vehicle is being driven on a rough or frozen road.
If the anti
-lock brake system warning light comes on,
the check tire pressure system may not be working
properly. See your dealer for service. (Also, see
ªAnti
-Lock Brake System Warning Lightº in the Index.)
The check tire pressure system detects differences
in tire rotation speeds that are caused by changes in
tire pressure. The system can alert you about a
low tire
-- but it doesn't replace normal tire
maintenance. See ªTiresº in the Index.
