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, do the following:
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)

6-48
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.

Electrical System
Add-On Electrical Equipment
NOTICE:
Don't add anything electrical to your vehicle
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 vehicle, see ªServicing
Your Air Bag
-Equipped Vehicleº in the Index.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of damage
caused by electrical problems.
Look at the silver
-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical size
and rating.
There are three fuse blocks in your vehicle: the
instrument panel fuse block located under the instrument
panel, the underhood fuse block located on the
passenger's side engine compartment and the rear fuse
block, located under the rear seat.

6-67
Instrument Panel Fuse Block and Bussed Electrical
Center (BEC)
The instrument panel fuse block and BEC are located
on the passenger's side of the vehicle, under the
instrument panel.
Remove the hush panel on the passenger's side to reveal
the fuses. To remove the panel, do the following:
1. Remove the two 7 mm screws located along the front
edge of the panel.
2. Lower the hush panel.
3. Remove the cover. Now you can see the fuses and
replace them.
4. Place the wide end of the fuse puller over the plastic
end of the fuse.
5. Squeeze the ends over the fuse and pull it out.
When finished, reinstall the hush panel. Reinstall lamps,
connectors, and HVAC duct temperature sensors if they
were removed.Instrument Panel Fuse Block
