Moisture-Sensing Delay Windshield Wipers
(If Equipped)
The moisture sensor is mounted on the passenger's
interior side of the windshield behind the rearview
mirror and is used to automatically operate the
wipers by monitoring the amount of moisture on
the windshield.The moisture
-sensing system is activated by turning the
wiper control band to one of the five sensitivity levels
within the delay area. The delay position closest to
OFF/MIST is the lowest sensitivity setting. This allows
more water to collect on the windshield between wipes.
You can increase the sensitivity of the system and the
frequency of wipes by turning the wiper control band
away from you to the other delay settings. A single wipe
will occur each time you turn the wiper control band to a
higher sensitivity level.
An initial wipe will occur when you turn the ignition on
and the wiper switch is left in one of the sensitivity
settings, as a reminder that the rain sense feature is active.
The moisture
-sensing wipers operate in a delay mode as
well as a continuous low or high speed, depending on the
amount of moisture on the windshield and the sensitivity
setting. The MIST and wash cycles operate as normal and
are not affected by the moisture
-sensing function.
NOTICE:
Turn the wiper band to OFF to avoid wiper damage
when going through an automatic car wash.

Pull the headlamp knob out to the first position to turn
on the parking, license and sidemarker lamps. Pull the
knob out further, to the second position, to turn on the
headlamps. Push the knob all the way back in to turn off
the parking and headlamps.
Lamps On Reminder
If you leave the manual headlamp or parking lamp
switch on, remove the key from the ignition and open
the driver's door, you will hear a continuous warning
chime. The chime will turn off when the lamps are
turned off.
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset.
A light sensor on top of the instrument panel monitors
the exterior light level for the operation of DRL and
Twilight Sentinel

, so be sure it isn't covered.
The DRL system will make your high
-beam headlamps
come on at reduced brightness in daylight when:

The ignition is on,

The headlamp switch is off, and

The transaxle is not in PARK (P).
When DRL are on, only your high
-beam headlamps will
be on. The parking lamps, taillamps, sidemarker and
other lamps won't be on. Your instrument panel won't
be lit up either.

2-44
When it's dark enough outside, your high-beam
headlamps will change to low
-beam headlamps at full
brightness. The other lamps that turn on with your
headlamps will also turn on. When it's bright enough
outside, the regular lamps will turn off, and your
high
-beam headlamps change to the reduced brightness
of DRL.
To idle your vehicle with the DRL off, shift the
transaxle into PARK (P). The DRL will stay off until
you shift out of PARK (P).
To turn off all exterior lighting at night when you are
parked, turn off the headlamps and move the Twilight
Sentinel control all the way to the left in the slider
control. When released, the control will return to the
Twilight Sentinel minimum delay position and the lights
will turn off.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Cornering Lamps
The cornering lamps are designed to come on when you
signal a turn. This will provide more light for cornering
at night.
Twilight Sentinel

Twilight Sentinel turns
your headlamps on and off
by sensing how dark it
is outside.
To operate this feature, slide the control to any position
to vary the lamp timeout.
If you move the control all the way to MAX, your lamps
will remain on for three minutes after you turn off your
engine. If you move the control almost all the way in the
other direction, so it's just on, the lamps will go off
quickly when you turn off your engine. You can set this
delay time from only a few seconds to three minutes.
Light Sensor
Your Twilight Sentinel and Daytime Running Lamps
work with the light sensor on top of the instrument
panel. Don't cover it up. If you do, it will read ªdarkº
and the headlamps will come on.

2-46 Parade Dimming
This feature prohibits the dimming of your instrument
panel displays during daylight while your headlamps are
on. This feature operates with the light sensor for the
Twilight Sentinel

and is fully automatic. When the
light sensor reads darkness outside, you will be able to
dim your instrument panel displays once again.
Perimeter Lighting
When the button with the unlock symbol on the remote
keyless entry transmitter is pressed, the daytime running
lamps, parking lamps and back
-up lamps will come on
if it is dark enough outside.
This feature will only be activated when the security
feedback feature is programmed to be in Modes 1, 3 or 5
on the transmitter. Modes 0, 2 and 4 do not respond with
exterior lights flashing when unlocking the vehicle so
perimeter lighting will not be active.
This feature can be programmed on or off for
each transmitter.
To turn the feature off:
1. Press and hold LOCK on the door lock switch on the
door throughout this procedure. All doors will lock.2. Press the instant alarm button on the transmitter to enter
the programming mode. Perimeter lighting remains on
at this time and the horn will chirp two times.
3. Press the instant alarm button on the key transmitter
again. Perimeter lighting is disabled and the horn
will chirp one time.
4. Release the door lock switch. The perimeter lighting
feature is now off.
To turn the feature on:
1. Press and hold LOCK on the door lock switch on the
door throughout this procedure. All doors will lock.
2. Press the instant alarm button on the key transmitter to
enter the programming mode. Perimeter lighting
remains off at this time and the horn will chirp one time.
3. Press the instant alarm button on the transmitter

optional Driver Information Center (DIC). See
ªPersonal Choice Featuresº or ªDriver Information
Centerº in the Index.

2-72 Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR BAG. The system checks the
air bag's electrical system for malfunctions. The light
tells you if there is an electrical problem. The system
check includes the air bag sensors, the air bag modules,
the wiring and the crash sensing and diagnostic module.
For more information on the air bag system,
see ªAir Bagº in the Index.
This light will come on
when you start your vehicle,
and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inflate in a crash, or they
could even inflate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the air bag readiness light
stays on after you start your vehicle.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to RUN. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.

During stops, when driving slow, or when the engine
is first started after a short trip, the outside temperature
reading can be affected by road or engine heat.
Also, starting the engine within a short time after the
vehicle has been running will affect the reading. To
ensure proper automatic climate control operation, the
outside temperature display may not update as quickly
as expected.
Sun and temperature sensors automatically adjust the
air temperature, the airflow direction and the fan speed
to maintain your comfort setting. The system may
supply cooler air to the side toward the sun. Be careful
not to put anything over the sensors on top of the dash.
Temperature Button
To adjust the comfort level you want maintained inside
the vehicle, push the TEMP button. If you want a
warmer comfort level, push the red arrow. If you want a
cooler comfort level, push the blue arrow. Your comfort
setting is shown in the display.Fan Button
The speed of the blower fan is controlled automatically
if you have the system set for AUTO. Pressing the
FAN button will display and hold the current blower
fan setting.
If you want the blower fan to run at a lower speed,
push the bottom of the FAN button. The fan speed will
decrease with every push of the button until the lowest
speed is reached. If you want to increase the fan speed,
push the top of the FAN button. Notice the fan
indicators on the display.
Mode Controls
Press the AIR FLOW button to deliver air through the
floor, middle or windshield outlets. The system will stay
in the selected mode until the AUTO button is pushed.
Press the up or down arrow on the AIR FLOW button to
cycle through the available modes.

6-67 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.Instrument Panel Fuse Block
The instrument panel fuse block is located to the far
right side 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. The fuse block is a
rectangular covered box located on the far right side
under the instrument 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.
Spare fuses are located in the empty slots shown on the
following chart.
When finished, reinstall the hush panel. Reinstall lamps,
connectors, and HVAC duct temperature sensors if they
were removed.
