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 Servicesºfor more information.
Replacement blades come in different types and are
removed in different ways. For proper type and length,
see ªNormal Maintenance Replacement Partsº in the
Index. Here's how to remove the wiper blades:
1. Turn on the wipers to the low wipe setting.
2. Turn off the ignition while the wipers are at the
outer positions of the wiper pattern. The blades are
more accessible for removal/replacement while in
this position.
3. Pull the windshield wiper arm away from
the windshield.
4. While holding the wiper arm away from the glass,
push the release clip from under the blade
connecting point and pull the blade assembly down
toward the glass to remove it from the wiper arm.
5. Push the new wiper blade securely on the wiper arm
until you hear the release clip ªclickº into place.

6-44 Tire Inflation Monitor System
The tire inflation monitor system can alert you to a large
change in the pressure of one tire. The system ªlearnsº
the pressure at each tire throughout the operating speed
range of your vehicle. The system normally takes
between 45 and 90 minutes of driving to learn the tire
pressures. This time may be longer depending on your
individual driving habits. Learning need not be
accumulated during a single trip. Once learned, the
system will remember the tire pressures until the system
is recalibrated.
After the system has learned tire pressures with properly
inflated tires, the LOW TIRE PRESSURE light will
come on if the pressure in one tire becomes 12 psi
(83 kPa) lower than the other three tires. The tire
inflation monitor system won't alert you if the pressure
in more than one tire is low, if the system is not properly
calibrated, or if the vehicle is moving faster than
70 mph (110 km/h).
The tire inflation monitor 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 LOW TIRE PRESSURE light comes on, 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.
The light will come on and stay on until you turn off the
ignition or reset (calibrate) the system.
Don't reset the tire inflation monitor 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 system
will not work properly and may not alert you when a tire
is low.
Any time you adjust a tire's pressure, rotate your tires,
or have one or more tires repaired or replaced, you'll
need to reset (calibrate) the tire inflation monitor
system. You'll also need to reset the system whenever
you buy new tires and whenever the vehicle's battery
has been disconnected.

6-45
To reset (calibrate) the system: The tire inflation
monitor system can be reset by turning the exterior lamp
control from OFF to parking lamps three times while the
ignition is in ON. It can also be reset through ªVehicle
Customization Settings.º To reset the monitor using the
vehicle customization settings:
1. Turn the ignition to ACC or ON and turn the
radio off.
2. Press and hold the DISP button on the radio for at
least five seconds until SETTINGS is displayed.
3. Press the SEEK up or down arrow to scroll through
the main menu.
4. Scroll until TIRE MON appears on the display.
5. Press the PREV or NEXT button to enter the
submenu. RESET will be displayed.
6. Press the DISP button to reset. A chime will be heard
to verify the new setting and DONE will be
displayed for one second.
7. Once the monitor has been reset, scroll until EXIT
appears on the display.
8. Press the DISP button to exit programming. A chime
will be heard to verify exit.The system completes the calibration process
during driving.
The system normally takes 15 to 20 minutes of driving
in each of three speed ranges to ªlearnº tire pressures.
The speed ranges are 15 to 40 mph (25 to 65 km/h),
40 to 65 mph (65 to 105 km/h) and above 65 mph
(105 km/h). When learning is complete, the system will
alert you after 2
-8 minutes if a tire is 12 psi (83 kPa)
different from the other three tires. Detection thresholds
may be higher and detection times may be longer on
rough roads, curves and at high speeds. The system
is not capable of detection at speeds greater than
70 mph (110 km/h).

Ignition Transaxle Lock Check
While parked, and with the parking brake set, try to turn
the ignition key to OFF in each shift lever position.

The key should turn to OFF only when the shift lever
is in PARK (P).

The key should come out only in OFF.
Parking Brake and Automatic Transaxle PARK (P)
Mechanism Check
CAUTION:
When you are doing this check, your vehicle
could begin to move. You or others could be
injured and property could be damaged. Make
sure there is room in front of your vehicle in case
it begins to roll. Be ready to apply the regular
brake at once should the vehicle begin to move.
Park on a fairly steep hill, with the vehicle facing
downhill. Keeping your foot on the regular brake,
set the parking brake.

To check the parking brake's holding ability: With
the engine running and transaxle in NEUTRAL (N),
slowly remove foot pressure from the regular brake
pedal. Do this until the vehicle is held by the parking
brake only.

To check the PARK (P) mechanism's holding ability:
With the engine running, shift to PARK (P). Then
release the parking brake followed by the
regular brake.
Underbody Flushing Service
At least every spring, use plain water to flush any
corrosive materials from the underbody. Take care to
clean thoroughly any areas where mud and other debris
can collect.
