What will you see after an air bag inflates?
After an air bag inflates, it quickly deflates, so quickly
that some people may not even realize the air bag
inflated. Some components of the air bag module
-- the
steering wheel hub for the driver's air bag, or the
instrument panel for the right front passenger's
bag
-- will be hot for a short time. The parts of the bag
that come into contact with you may be warm, but not
too hot to touch. There will be some smoke and dust
coming from vents in the deflated air bags. Air bag
inflation doesn't prevent the driver from seeing or from
being able to steer the vehicle, nor does it stop people
from leaving the vehicle.
CAUTION:
When an air bag inflates, there is dust in the air.
This dust could cause breathing problems for
people with a history of asthma or other
breathing trouble. To avoid this, everyone in the
vehicle should get out as soon as it is safe to do so.
If you have breathing problems but can't get out
of the vehicle after an air bag inflates, then get
fresh air by opening a window or door.
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 they
inflate, 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 air bag system. The module records information
about the readiness of the system, when the sensors
are activated and driver's safety belt usage
at deployment.

Let only qualified technicians work on your air bag
system. Improper service can mean that your 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, the bag may not
work properly. You may have to replace the air
bag module in the steering wheel or both the air
bag module and the instrument panel for the
right front passenger's air bag. Do not open or
break the air bag coverings.
If your vehicle ever gets into a lot of water -- such as
water up to the carpeting or higher
-- or if water enters
your vehicle and soaks the carpet, the air bag controller
can be soaked and ruined. If this ever happens, and then
you start your vehicle, the damage could make the air
bags inflate, even if there's no crash. You would have to
replace the air bags as well as the sensors and related
parts. If your vehicle is ever in a flood, or if it's exposed
to water that soaks the carpet, you can avoid needless
repair costs by turning off the vehicle immediately and
disconnecting the battery cables. Don't let anyone start
the vehicle under any circumstances. See your dealer
for service.
Servicing Your Air Bag-Equipped Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag system in several places
around your vehicle. You don't want the system to
inflate while someone is working on your vehicle. Your
dealer and the Aurora Service Manual have information
about servicing your vehicle and the air bag system. To
purchase a service manual, see ªService and Owner
Publicationsº in the Index.
CAUTION:
For up to 10 minutes after the ignition key is
turned off and the battery is disconnected, an air
bag can still inflate during improper service. You
can be injured if you are close to an air bag when
it inflates. Avoid yellow connectors. They are
probably part of the air bag system. Be sure to
follow proper service procedures, and make sure
the person performing work for you is qualified
to do so.
The air bag system does not need regular maintenance.

Ending Cruise Control
There are two ways to turn off the cruise control:

Step lightly on the brake pedal, or

Move the cruise switch to OFF. The CRUISE light
will also go out.
Erasing Speed Memory
When you turn off the cruise control or the ignition,
your cruise control set speed memory is erased.
Exterior Lamps
Headlamps
See ªTurn Signal/Multifunction Leverº in the Index.
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 makes the
DRL work, so be sure it isn't covered.The DRL system will make your low
-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 low
-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.
When it's dark enough outside, your low
-beam headlamps
will change to full brightness. The other lamps that come
on with your headlamps will also come on. When it's
bright enough outside, the regular lamps will go off, and
your low
-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 in
PARK (P), turn off the headlamps and move the twilight
sentinel control, located to the left of the steering
column, all the way toward MIN. See ªTwilight
Sentinelº in the Index.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

2-44 Twilight Sentinel


Twilight sentinel turns the
headlamps, taillamps and
parking lamps on and off
by sensing how dark it
is outside.
To operate it, leave the headlamp switch off and move
the twilight sentinel control toward MAX. The control is
located to the left of the steering column.
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 toward MIN, the lamps will go off
quickly when you turn off your engine. You can set this delay
time for only a few seconds or up 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.
Interior Lamps
Instrument Panel Brightness Control
You can brighten or dim your instrument cluster, radio and
climate control displays and control lights by rotating the
INTERIOR LIGHTS control between LO and HI when
your lights are on. Rotate the control all the way to HI and
you will turn on the interior courtesy lamps.
Courtesy Lamps
When any door is opened, several lamps go on. They
make it easy for you to enter and leave the car. To turn
on these lamps, rotate the INTERIOR LIGHTS knob all
the way to HI.

2-45 Illuminated Entry
Press the UNLOCK button on the remote lock control
transmitter and the interior courtesy lamps will come on
and stay on for up to one minute. The lamps will turn off
immediately by pressing the LOCK button on the
remote lock control transmitter, starting the ignition or
activating the power door locks.
Delayed Illumination
When you open the door to enter your vehicle, the
interior lamps will come on. When you close the door
with the ignition off, the interior lamps will stay on for
25 seconds or until the ignition is turned on. Note that
locking the doors with the power door lock switch will
override the delayed illumination feature and the lights
will turn off right away.
Theater Dimming
This feature allows for a three to five-second fade out of
the courtesy lamps instead of immediate turn off. They
will not fade if the interior lights switch is used.
Exit Lighting
With this feature, the interior lamps will come on for
25 seconds after you remove the key from the ignition.
This will give you time to find the door pull handle or
lock switches when you exit the vehicle.
Parade Dimming
This feature prohibits the dimming of your instrument
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 UNLOCK button on the remote lock control
transmitter is pressed, the headlamps, parking lamps,
back
-up lamps and cornering lamps will come on if it is
dark enough outside according to the twilight sentinel.
This feature can be programmed on or off for each
driver's transmitter.
To turn the feature off:
1. Turn the ignition key to OFF.
2. Press and hold the door lock switch throughout this
procedure. All doors will lock.

When one of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual's advice.
Waiting to do repairs can be costly
-- and even
dangerous. So please get to know your warning lights
and gages. They're a big help.
Your vehicle may also have a driver information system
that works along with the warning lights and gages. See
ªDriver Information Systemº in the Index.
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for about eight seconds to remind people to
fasten their safety belts.
The safety belt light will
also come on and stay on
for about 70 seconds. If the
driver's belt is already
buckled, neither the chime
nor the light will come on.
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 engine,
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
engine or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
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.

In cold weather, the system will delay turning on the fan
to avoid blowing cold air. The length of the delay
depends on the engine coolant temperature and the
outside temperature. Turning the AUTO FAN knob will
override this delay by turning off the automatic fan
mode and changing the fan speed.
Your automatic electronic climate control system has
two sun sensors located on the top of the instrument
panel that detect direct sunlight. To keep you and your
passengers comfortable, the system may supply cooler
air to the side toward the sun. Be careful not to put
anything over these sun sensors. The automatic
electronic climate control system may not operate
correctly if these sensors are covered.To change the automatic electronic climate control
display from an English display to a metric display, push
the OFF button located in the Driver Information Center
(DIC) for two seconds. The display in the DIC will also
change from an English to a metric display. To return to
an English display, repeat the above procedure.
Manual Operation
You may override the automatic airflow distribution by
turning the AUTO
-PUSH knob. After you turn this
knob, the comfort setting will be displayed for five
seconds, then the outside temperature will be displayed.
The fan control will remain in the automatic control
mode unless you turn the AUTO FAN knob to select a
manual fan speed.
UPPER: This setting directs airflow through the
upper air outlets located in the instrument panel and
door panels.
BI-LEVEL: This setting directs the airflow
through both the upper air outlets and the lower floor
outlets. There is also a small amount of air directed to
the front defroster and the side window defrosters.
HEAT: This setting directs most of the airflow to
the lower floor outlets with some airflow directed to the
side window defrosters. There is also a small amount of
airflow directed to the front defroster.
