There is an air bag readiness
light on the instrument
panel, which shows the
air bag symbol.
The system checks the air bag electrical system for
malfunctions. The light tells you if there is an electrical
problem. See ªAir Bag Readiness Lightº in the Index
for more information.How the Air Bag System Works
Where are the air bags?
The driver's air bag is in the middle of the
steering wheel.

The right front passenger's air bag is in the instrument
panel on the passenger's side.
CAUTION:
If something is between an occupant and an air
bag, the bag might not inflate properly or it
might force the object into that person. The path
of an inflating air bag must be kept clear. Don't
put anything between an occupant and an air
bag, and don't attach or put anything on the
steering wheel hub or on or near any other air
bag covering.
When should an air bag inflate?
An air bag is designed to inflate in a moderate to severe
frontal or near
-frontal crash. The air bag will inflate only if
the impact speed is above the system's designed ªthreshold
level.º If your vehicle goes straight into a wall that doesn't
move or deform, the threshold level is about 9 to 14 mph
(14 to 23 km/h). The threshold level can vary, however,
with specific vehicle design, so that it can be somewhat
above or below this range. If your vehicle strikes
something that will move or deform, such as a parked car,
the threshold level will be higher. The air bag is not
designed to inflate in rollovers, side impacts or rear
impacts, because inflation would not help the occupant.

In any particular crash, no one can say whether an air bag
should have inflated simply because of the damage to a
vehicle or because of what the repair costs were. Inflation
is determined by the angle of the impact and how quickly
the vehicle slows down in frontal or near
-frontal impacts.
What makes an air bag inflate?
In an impact of sufficient severity, the air bag sensing system
detects that the vehicle is in a crash. The sensing system
triggers a release of gas from the inflator, which inflates the
air bag. The inflator, air bag and related hardware are all part
of the air bag modules inside the steering wheel and in the
instrument panel in front of the right front passenger.
How does an air bag restrain?
In moderate to severe frontal or near
-frontal collisions,
even belted occupants can contact the steering wheel or the
instrument panel. Air bags supplement the protection
provided by safety belts. Air bags distribute the force of
the impact more evenly over the occupant's upper body,
stopping the occupant more gradually. But air bags would
not help you in many types of collisions, including
rollovers, rear impacts and side impacts, primarily because
an occupant's motion is not toward those air bags. Air
bags should never be regarded as anything more than a
supplement to safety belts, and then only in moderate to
severe frontal or near
-frontal collisions.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 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.

Auto-Down Switch
The driver's window switch has an auto
-down feature.
This switch is labeled AUTO. Push the top of the switch
partway, and the driver's window will open a small
amount. If the switch is pushed all the way, the window
will go all the way down.
To stop the window while it is lowering, push the switch
forward. To raise the window, push and hold the
switch forward.
Lock
-Out Switch
On four
-door models, the driver's power window
controls also include a lock
-out switch. When the
lockout switch is moved to the left (with the white stripe
showing), the driver and passengers will be able to use
their window switches. Move the lockout switch to the
right to stop the passengers from using their window
switches. The driver can still control all the windows
with the lock on.
Horn
You can sound the horn by pressing the horn symbol on
your steering wheel.
Tilt Wheel
A tilt steering wheel allows you to adjust the steering
wheel before you drive.
You can also raise it to the highest level to give your
legs more room when you exit and enter the vehicle.
To tilt the wheel, hold the steering wheel and pull the
lever toward you.
Move the steering wheel to a comfortable level, then
release the lever to lock the wheel in place.

CAUTION:
In freezing weather, don't use your washer until
the windshield is warmed. Otherwise the washer
fluid can form ice on the windshield, blocking
your vision.
When you release the button, the washers will stop, but
the wipers will continue to wipe for about three times or
will resume the speed you were using before.
Cruise Control
The cruise control buttons are located on the
steering wheel.
With cruise control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your foot
on the accelerator. This can really help on long trips.
Cruise control does not work at speeds below
25 mph (40 km/h).
When you apply your brakes or the parking brake or the
BRAKE light is on or you have low brake fluid, the
cruise control will turn off.

2-41 Automatic Light Control (ALC)
When it is dark enough outside, your Automatic Light
Control (ALC) will turn on your headlamps along with
other lamps such as the taillamps, sidemarker lamps,
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. This will cause the ALC system to
be on whenever the ignition is on.
The ALC system may also come on when driving
through a parking garage, heavy overcast weather or 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
parking brake while the ignition is off. Then start the
vehicle. The ALC system will stay off until you release
the parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Delayed Headlamps
The delayed headlamps feature will continue to
illuminate the headlamps for 20 seconds after the key is
turned to OFF.
To turn off the delayed headlamps feature, turn the turn
signal/multifunction lever up one position and then back
to OFF.
Fog Lamps (If Equipped)
The button for your fog lamps is located on the
instrument panel, to the left of the steering wheel, beside
the instrument panel intensity control.
When using the 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.

Interior Lamps
Instrument Panel Intensity Control
You can brighten or dim the
instrument panel cluster
lights by moving the
thumbwheel up to increase
intensity and to down to
decrease intensity. The
thumbwheel is located on
the instrument panel to the
left of the steering wheel.
Courtesy Lamp Control
When the thumbwheel for the instrument panel intensity
control is moved up, the dome lamp, the mirror reading
lamps (if equipped) and the footwell lamps will turn on.
Move the thumbwheel down to turn the lamps off.
Illuminated Entry/Exit System
When you lift the driver's door handle or open the
driver's door, the lamps inside your vehicle will go on.
These lamps will fade out after about 10 seconds, or
when the ignition is turned on after all doors have been
closed. These lamps will also go on when you press the
trunk release or UNLOCK button on the remote lock
control transmitter (if equipped).
The lamps inside your vehicle will stay on for about
10 seconds after your key is removed from the ignition
to provide an illuminated exit.

4-11 Braking in Emergencies
With anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even the very best braking.
Steering
Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer but
it will take much more effort.
Variable Effort Steering (If Equipped)
This steering system provides lighter steering effort for
parking and at low vehicle speeds. Steering effort will
increase at higher speeds for improved road feel.
Steering Tips
Driving on Curves
It's important to take curves at a reasonable speed.
A lot of the ªdriver lost controlº accidents mentioned on
the news happen on curves. Here's why:Experienced driver or beginner, each of us is subject to
the same laws of physics when driving on curves. The
traction of the tires against the road surface makes it
possible for the vehicle to change its path when you turn
the front wheels. If there's no traction, inertia will keep
the vehicle going in the same direction. If you've ever
tried to steer a vehicle on wet ice, you'll understand this.
The traction you can get in a curve depends on the
condition of your tires and the road surface, the angle
at which the curve is banked, and your speed.
While you're in a curve, speed is the one factor you
can control.
Suppose you're steering through a sharp curve.
Then you suddenly accelerate. Both control
systems
-- steering and acceleration -- have to
do their work where the tires meet the road. Adding the
sudden acceleration can demand too much of those
places. You can lose control. Refer to ªEnhanced
Traction Systemº in the Index.
What should you do if this ever happens? Ease up on the
accelerator pedal, steer the vehicle the way you want it
to go, and slow down.
Speed limit signs near curves warn that you should
adjust your speed. Of course, the posted speeds are
based on good weather and road conditions. Under less
favorable conditions you'll want to go slower.
ProCarManuals.com

4-12
If you need to reduce your speed as you approach a
curve, do it before you enter the curve, while your front
wheels are straight ahead.
Try to adjust your speed so you can ªdriveº through
the curve. Maintain a reasonable, steady speed. Wait to
accelerate until you are out of the curve, and then
accelerate gently into the straightaway.
Steering in Emergencies
There are times when steering can be more effective
than braking. For example, you come over a hill and
find a truck stopped in your lane, or a car suddenly pulls
out from nowhere, or a child darts out from between
parked cars and stops right in front of you. You can
avoid these problems by braking
-- if you can stop
in time. But sometimes you can't; there isn't room.
That's the time for evasive action
-- steering around
the problem.
Your vehicle can perform very well in emergencies like
these. First apply your brakes. (See ªBraking in
Emergenciesº earlier in this section.) It is better to
remove as much speed as you can from a possible
collision. Then steer around the problem, to the left
or right depending on the space available.
An emergency like this requires close attention and a
quick decision. If you are holding the steering wheel at
the recommended 9 and 3 o'clock positions, you can
turn it a full 180 degrees very quickly without removing
either hand. But you have to act fast, steer quickly, and
just as quickly straighten the wheel once you have
avoided the object.
The fact that such emergency situations are always
possible is a good reason to practice defensive driving at
all times and wear safety belts properly.
