Your vehicle has a feature that will automatically unlock
the doors and turn the interior lamps on when the air
bags inflate (if battery power is available). You can lock
the doors again and turn the interior lamps off by using
the door lock and interior lamp controls.
In many crashes severe enough to inflate an air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger air bag.

Air bags are designed to inflate only once. After an
air bag inflates, you'll need some new parts for your
air bag system. If you don't get them, the air bag
system won't be there to help protect you in another
crash. A new system will include air bag modules
and possibly other parts. The service manual for your
vehicle covers the need to replace other parts.

Your vehicle is equipped with a crash sensing and
diagnostic module, which records information about
the frontal air bag system. The module records
information about the readiness of the system, when
the system commands air bag inflation and driver's
safety belt usage at deployment. Some modules also
record speed, engine rpm, brake and throttle data.
Let only qualified technicians work on your
air bag systems. Improper service can mean that
an air bag system won't work properly. See your
dealer for service.
NOTICE:
If you damage the covering for the driver's or
the right front passenger's air bag, or the air bag
covering on the driver's and right front
passenger's seatback, the bag may not work
properly. You may have to replace the air bag
module in the steering wheel, both the air bag
module and the instrument panel for the right
front passenger's air bag, or both the air bag
module and seatback for the driver's and right
front passenger's side impact air bag. Do not
open or break the air bag coverings.

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.

FRONT: This selection is used to defrost the windshield
by directing the airflow toward the windshield.
If FRONT is selected while in the AUTO mode, the fan
speed and the air temperature from the front defroster will
vary. If a manual fan speed setting is selected, the fan
speed will remain at that selection until another fan speed
selection is made or the AUTO mode is selected. To turn
off FRONT, press the AUTO or AIR FLOW button.
FRONT defrost will work better if any ice or snow is
cleared from the hood and the air inlet area between the
base of the windshield and the hood.
Air Conditioning
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
If you have the electronic touch system, for quick
cool
-down on very hot days, use MAX with the
temperature and fan speed adjusted to COOL and
HIGH. If this setting is used for long periods of time, the
air in your vehicle may become too cold and dry.For normal cooling on hot days, use NORM and adjust the
temperature and fan speed for your comfort. If RECIRC is
selected while in the NORM air conditioning mode, the
system works like MAX and recirculates the air.
On sunny days, when the air is moderately warm or
cool, use BI
-LEV to deliver warm air to the floor and
cooler air to the middle instrument panel outlets. On
days like these, the sun may adequately warm your
upper body, but your lower body may not be warm
enough. To warm or cool the air delivered, adjust the
TEMPERATURE lever.
The amount of fresh air entering the vehicle is limited
when RECIRC is selected. This is helpful when you are
trying to cool the air in your vehicle or limit the air
entering the vehicle.
If your vehicle has the Dual Automatic Comfortemp
system and it is set for AUTO, on very hot days, the
system will automatically enter the RECIRC mode and
the temperature door will be positioned at the full cold
position for maximum cooling. If the system is not in
the AUTO mode, RECIRC should be selected to provide
maximum cooling. You can choose the extreme comfort
setting of 60
F (16
C), but the system will not cool any
faster by choosing the extreme comfort setting.
