Windshield Wiper Blade Replacement
Windshield wiper blades should be inspected at least
twice a year for wear or cracking. See ªWiper Blade
Checkº in Section 7 of this manual under Part B ªOwner
Checks and Servicesº for more information.
Replacement blades come in different types and are
removed in different ways.
To replace the wiper blade assembly:
1. Lift the windshield wiper arm away from
the windshield.
2. 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.
3. Remove the blade.
4. 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 proper 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)
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 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.
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: CHECK TIRES 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.
When the TIRE PRESSURE LOW: CHECK TIRES
message appears on the Driver Information Center, you
should stop as soon as you can and check all your tires
for damage. (If a tire is flat, see ªIf a Tire Goes Flatº in
the Index.) Also check the tire pressure in all four tires
as soon as you can. See ªInflation
-Tire Pressureº
in the Index.
Any time you adjust a tire's pressure or have one or
more tires repaired or replaced, you'll need to reset
(calibrate) the check tire pressure system. You'll also
need to reset the system whenever you rotate the tires,
buy new tires, install or remove the compact spare, and
whenever the vehicle's battery has been disconnected.Don't reset the check tire pressure system without first
correcting the cause of the problem and checking and
adjusting the pressure in all four tires. If you reset the
system when the tire pressures are incorrect, the check
tire pressure system will not work properly and may not
alert you when a tire is low or high.
To reset (calibrate) the system:
1. Turn the ignition switch to RUN.
2. Press the GAGE INFO button on the DIC until
TIRE PRESSURE appears on the display.
3. Press and hold the DIC RESET button for about
five seconds. After five seconds, the display will
show TIRE PRESSURE RESET. If TIRE
PRESSURE RESET does not appear in the display
after about five seconds retry the process. If it does
not work after two tries, see your dealer for service.
After you release the DIC RESET button, TIRE
PRESSURE NORMAL will appear in the display.
The system completes the calibration process during
driving. Calibration time can take 45 to 90 minutes,
depending on your driving habits. After the system has
been calibrated, the system will alert the driver that a tire
is low, up to a maximum speed of 65 mph (105 km/h).

6-45 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
ªWhen It's Time for New Tiresº and ªWheel
Replacementº 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 ªScheduled Maintenance Servicesº in
the Index 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.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the Tire
-Loading
Information label. Reset the Make certain that all wheel
nuts are properly tightened. See ªWheel Nut Torqueº in
the Index.
CAUTION:
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 ªChanging a Flat Tireº in the Index.)
