2-39 Rainsense
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 that is on the windshield.
The Rainsense system can be activated by turning the
wiper control band to one of the five sensitivity settings
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 setting.
An initial wipe occurs when you turn the ignition on as a
reminder that Rainsense is active.
The Rainsense 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 ªwashº cycles operate as normal
and are not affected by the Rainsense function.NOTICE:
The wipers must be turned off when going
through a car wash to avoid damage.
It is important to note that the Rainsense delay wiping
feature can be overridden at any time by manually
changing the wiper control to LO or HI speed.
NOTICE:
Do not place stickers or other items on the
exterior glass surface directly in front of the
rainsensor. Doing this could cause the rainsensor
to malfunction.

To operate the wiper-activated headlamps, the Twilight
Sentinel must be on. If the wiper
-activated headlamps
are on and the ignition switch is turned to RUN, the
wiper
-activated headlamps will continue. When you
turn the key to OFF/UNLOCK, the wiper
-activated
headlamps will immediately turn off. The
wiper
-activated headlamps will also turn off if you
turn off the Twilight Sentinel or the windshield wipers.
Parking Lamps
Press the PARK button to turn on the parking lamps.
Press it again to turn them off. (If the parking lamps
were turned on with the PARK button, they must be
turned off with that button).
When the parking lamps are turned on during the day,
the instrument panel cluster lights and backlighting to
buttons will turn on. At night, the brightness of this
lighting can be adjusted by the instrument panel
intensity/brightness control if the ignition key is turned
to RUN. The radio and climate control displays will also
be on. When it becomes dark outside, the instrument
panel intensity/brightness control will operate all
instrument panel lighting.
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
turn 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 the DRL are on, only your high
-beam headlamps
will be on. The parking lamps, taillamps, sidemarker
and other lamps won't be on.

Park Lamp Override Feature
If the Twilight Sentinel lighting is active, it can be
disabled by turning on the manual parking lamps. The
lighting will be disabled until the ignition is moved from
RUN or until the outside light level becomes daylight.
The outside light level changing to daylight will cause
the Twilight Sentinel feature to deactivate. If it becomes
dark again, the parking lamps will have to be turned on
again. (If the parking lamps are already on, they will
have to be turned off, then back on to disable twilight).
The wiper
-activated headlamps will override the
twilight disable feature.
Light Sensor
Your Twilight Sentinel and
DRL work with the light
sensor located on top of the
instrument panel.
Don't cover it up. If you do, the sensor will read ªdarkº
and the Twilight Sentinel lighting will turn on.
Interior Lamps
Instrument Panel Intensity/
Brightness Control
The brightness of the
instrument panel lights can
be adjusted by moving the
INTERIOR lever between
LO and HI.
The instrument panel lights will be on only when the
parking lamps are on. The interior courtesy lamps can
be turned on by sliding the INTERIOR lever all the way
to the top, to HI.

2-68 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.

3-4 Dual Automatic Comfortemp
Climate Control (If Equipped)
If your vehicle is equipped with the Dual Automatic
Comfortemp Climate Control system, the following
information tells you how it works.You will hear a beep each time a button is pushed and a
light on the button will indicate which function is active.
The lights are on all buttons except TEMP, FAN and
AIR FLOW. The display will show fan speed, comfort
level setting and airflow direction for a few seconds
whenever AUTO is selected, and then it will display the
outside temperature. The outside temperature reading is
most accurate when the vehicle is moving. During stops,
the display shows the previous temperature for best
accuracy and system control.
If the display is flashing after the climate control system
is started, there is a problem with the system and you
should see your dealer for service.
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 of the vehicle toward the
sun. Be careful not to put anything over the sensor on
top of the dash.

Adjust the direction of
airflow by moving the
louvered vents.
If you have the optional rear
passenger comfortemp, you
can adjust the direction of
the airflow to the rear
seating area.Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction such as leaves. The heater and
defroster will work better, reducing the chance of
fogging your windows.

Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.

When the engine idles for a long time, the exterior
temperature sensor may cause the system to blow air
that is too cool. Once the vehicle is moving again,
the system will try to maintain the set temperature
inside your vehicle.

When you start your vehicle and the EXT display
flashes (Dual Automatic Comfortemp system only)
for some time, the system may need repair.
See your dealer.
