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. For proper type and length,
see ªNormal Replacement Partsº in the Index.
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.

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.

6-50 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.
When the TIRE PRESSURE LOW 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 and install or remove the compact spare.
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.

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 in the engine
compartment on the passenger's side of the vehicle and
the rear fuse block, located under the rear seat.

6-68
Main and Auxiliary Instrument Panel Fuse Blocks
The main and auxiliary instrument panel fuse blocks are
located on the passenger's side of the vehicle, under the
instrument panel. Lamps, connectors and the HVAC
duct temperature sensors may need to be disconnected
and removed to allow access to these fuse blocks.
Remove the hush panel on the passenger's side to reveal
the fuses by performing the following steps:
1. Remove the two screws located along the front edge
of the panel.
2. Lower the hush panel.
3. Remove the fuse block cover.
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 fuse block cover and the
hush panel. Reinstall lamps, connectors and HVAC duct
temperature sensors if they were removed.Main Instrument Panel Fuse Block
