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 system
commands air bag inflation 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.

AUTOMATIC OVERDRIVE (D): This position is
for normal driving. If you need more power for passing,
and you're:

Going less than 35 mph (56 km/h), push your
accelerator pedal about halfway down.

Going about 35 mph (56 km/h) or more, push the
accelerator all the way down. You'll shift down to
the next gear and have more power.
NOTICE:
If your vehicle seems to start up rather slowly, or
if it seems not to shift gears as you go faster,
something may be wrong with a transaxle system
sensor. If you drive very far that way, your
vehicle can be damaged. So, if this happens, have
your vehicle serviced right away. Until then, you
can use SECOND (2) when you are driving
less than 35 mph (56 km/h) and AUTOMATIC
OVERDRIVE (D) for higher speeds.
THIRD (3): This position is also used for normal
driving, however, it offers more power and lower fuel
economy than AUTOMATIC OVERDRIVE (D). Here
are some times you might choose THIRD (3) instead of
AUTOMATIC OVERDRIVE (D):

When driving on hilly, winding roads.

When towing a trailer, so there is less shifting
between gears.

When going down a steep hill.
SECOND (2): This position gives you more power but
lower fuel economy. You can use SECOND (2) on hills.
It can help control your speed as you go down steep
mountain roads, but then you would also want to use
your brakes off and on.

Turn the turn signal lever end cap up two positions to
turn on:

Headlamps

Parking Lamps

Sidemarker Lamps

Taillamps

License Plate Lamps

Instrument Panel Lights
Turn the switch to OFF to turn all of the lamps off.
Lamps On Reminder
If you open the driver's door and turn off the ignition
while leaving the lamps on, you will hear a
warning chime.
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.The DRL system will make your low
-beam headlamps
come on at a reduced brightness when:

the ignition is on,

the headlamp switch is to OFF or you have turned on
your parking lamps,

the light sensor detects daytime light,

the parking brake is released and

the shift lever is not in PARK (P).
When the DRL system is on, the taillamps, sidemarker,
park lamps and instrument panel lights will not
be illuminated.
The DRL system will remain off any time your vehicle
is in PARK (P) or the parking brake is engaged.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

2-38 Automatic Light Control (ALC)
When it is dark enough outside, your Automatic Light
Control (ALC) will turn on your headlamps at the
normal brightness along with other lamps such as the
taillamps, sidemarker, park lamps and the instrument
panel lights. The radio lights will also be dim.
Your vehicle is equipped with a light sensor on the top
of the instrument panel under the defroster grill, so be
sure it is not covered which will cause the ALC system
to be on whenever the ignition is on.
The ALC system may also be on when driving through
a parking garage, heavy overcast weather, a tunnel.
This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the DRL and the ALC
systems so that driving under bridges or bright overhead
street lights does not affect the system. The DRL and
ALC systems will only be affected when the light sensor
sees a change in lighting lasting longer than this delay.
To idle your vehicle with the ALC system off, set the
park brake while the ignition is off. Then start the
vehicle. The ALC system will stay off until you release
the park brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Fog Lamps (If Equipped)
The button for your fog
lamps is on the instrument
panel, to the left of the
steering wheel, beside
the instrument panel
intensity control.
When using fog lamps, the ignition must be on as well
as the parking lamps or the low
-beam headlamps.
Push the button to turn the fog lamps on. An indicator
light on the button will glow when the fog lamps are on.
Push the button again to turn the fog lamps off.
The fog lamps will turn off whenever the high
-beam
headlamps are turned on. When the high beams are
turned off, the fog lamps will come on again.

2-51 Safety Belt Reminder Light
When the key is turned to ON or START, a chime will
come on for about eight seconds to remind people to
fasten their safety belts, unless the driver's safety belt is
already buckled.
The safety belt light will also come on and stay on for
about 20 seconds, then it will flash for about 55 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 the air bag symbol. 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 sensor, 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 ON. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.
