indicators may not fall exactly on the ª0º (zero) marks on
their scales.

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.

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).

CAUTION:
A safety belt that isn't properly routed through
the seat cushion or is twisted won't provide the
protection needed in a crash. If the safety belt
hasn't been routed through the seat cushion at
all, it won't be there to work for the next
passenger. The person sitting in that position
could be badly injured. After reinstalling the seat
cushion, always check to be sure that the safety
belts are properly routed and are not twisted.
1. Buckle the center passenger position safety belt, then
route the safety belts through the proper slots in the
seat cushion. Don't let the safety belts get twisted.
2. Slide the rear of the cushion up and under the
seatback so the rear
-locating guides hook into the
wire loops on the back frame.3. With the seat cushion lowered, push rearward and
then press down on the seat cushion until the spring
locks on both ends engage.
4. Check to make sure the safety belts are properly
routed and that no portion of any safety belt is
trapped under the seat. Also make sure the seat
cushion is secured.
Rear Underseat Bussed Electrical Center (BEC)
The rear BEC is located
beneath the rear seat on the
driver's side. The rear seat
cushion must be removed to
access the BEC. See
ªRemoving the Rear Seat
Cushionº in the Index.
