What Makes an Airbag Inate?
In an impact of sufficient severity, the airbag sensing
system detects that the vehicle is in a crash. The sensing
system triggers a release of gas from the inflator, which
inflates the airbag. The inflator, the airbag and related
hardware are all part of the airbag modules. Frontal
airbag modules are located inside the steering wheel and
instrument panel. For seating positions with side impact
airbags, there are also airbag modules in the side of the
seatbacks closest to the door.
How Does an Airbag Restrain?
In moderate to severe frontal or near frontal collisions,
even belted occupants can contact the steering wheel or
the instrument panel. In moderate to severe side
collisions, even belted occupants can contact the inside
of the vehicle. The airbag supplements the protection
provided by safety belts. Airbags distribute the force of
the impact more evenly over the occupant’s upper body,
stopping the occupant more gradually. But the frontal
airbags would not help you in many types of collisions,
including rollovers, rear impacts, and many side impacts,
primarily because an occupant’s motion is not toward the
airbag. Side impact airbags would not help you in many
types of collisions, including many frontal or near frontal
collisions, and rear impacts, primarily because an
occupant’s motion is not toward those airbags. Airbags
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 for the frontal
airbags, and only in moderate to severe side collisions for
vehicles with a side impact airbag.

What Will You See After an Airbag
Inates?
After the airbag inflates, it quickly deflates, so quickly
that some people may not even realize the airbag
inflated. Some components of the airbag module may
be hot for a short time. These components include
the steering wheel hub for the driver’s frontal airbag and
the instrument panel for the right front passenger’s
frontal airbag. For seating positions with side impact
airbags, the side of the seatback closest to the door may
be hot. The parts of the airbag that come into contact
with you may be warm, but not too hot to touch.
There will be some smoke and dust coming from the
vents in the deflated airbags. Airbag inflation does
not prevent the driver from seeing out of the windshield
or being able to steer the vehicle, nor does it stop
people from leaving the vehicle.
{CAUTION:
When an airbag inates, 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
cannot get out of the vehicle after an airbag
inates, then get fresh air by opening a
window or a door. If you experience breathing
problems following an airbag deployment, you
should seek medical attention.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front or
sides of the vehicle that could keep the
airbags from working properly?
A:Yes. If you add things that change your vehicle’s
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system from
working properly. Also, the airbag system may
not work properly if you relocate any of the airbag
sensors. If you have any questions about this,
you should contact Customer Assistance before you
modify your vehicle. The phone numbers and
addresses for Customer Assistance are in Step Two
of the Customer Satisfaction Procedure in this
manual. SeeCustomer Satisfaction Procedure on
page 7-2.
Q:Because I have a disability, I have to get my
vehicle modied. How can I nd out whether
this will affect my airbag system?
A:Changing or moving any parts of the front seats,
safety belts, the airbag sensing and diagnostic
module, steering wheel, the instrument panel, or
airbag wiring can affect the operation of the airbag
system. If you have questions, call Customer
Assistance. The phone numbers and addresses for
Customer Assistance are in Step Two of the
Customer Satisfaction Procedure in this manual.
SeeCustomer Satisfaction Procedure on page 7-2.

Restraint System Check
Checking the Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors
and anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, have it repaired.
Torn or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces. If a belt
is torn or frayed, get a new one right away.Also look for any opened or broken airbag covers, and
have them repaired or replaced. (The airbag system
does not need regular maintenance.)
Notice:If you damage the covering for the driver’s
or the right front passenger’s frontal airbag, or an
airbag covering (if equipped) on a seatback, the
airbag may not work properly. You may have to
replace the airbag module in the steering wheel, both
the airbag module and the instrument panel for the
right front passenger’s frontal airbag, or both the
airbag module and the seatback for seating positions
with a side impact airbag (if equipped.) Do not open
or break the airbag coverings.

Ignition Positions
With the key in the ignition
switch, you can turn the
key to four different
positions.
{CAUTION:
On manual transaxle vehicles, turning the key
to LOCK and removing it will lock the steering
column and result in a loss of ability to steer
the vehicle. This could cause a collision. If you
need to turn the engine off while the vehicle is
moving, turn the key only to ACC. Do not push
the key in while the vehicle is moving.Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is all the way in. If
it is, turn the steering wheel left and right while you
turn the key hard. If none of this works, then
your vehicle needs service.
LOCK:This position locks your steering wheel, ignition,
shift lever and transaxle. This is the only position in which
you can insert or remove the key. For easier key
operation when unlocking the steering wheel, move the
steering wheel from right to left and turn the key to ACC.
ACC (Accessory):This position operates some of your
electrical accessories, such as the radio, but not the
climate control system.
ON:This is the position to which the switch returns
after you start your engine and release the key.
The switch stays in ON when the engine is running. But
even when the engine is not running, you can use
ON to operate your electrical accessories, and to display
some instrument panel warning lights.
START:This position starts the engine. When the
engine starts, release the key. The switch will return to
ON for normal driving. Do not turn the key to START
if the engine is running.
Even if the engine is not running, ACC and ON allow
you to operate electrical accessories, such as the radio.

Hazard Warning Flashers
Your hazard warning flashers let you warn others. They
also let police know you have a problem. Your front
and rear turn signal lamps will flash on and off.
The hazard warning
flasher button is located
in the center of the
instrument panel.
Your hazard warning flashers work no matter what
position your key is in, and even if the key is not in the
ignition switch.
Press the button to make the front and rear turn signal
lamps flash on and off. Press the button again to
turn the flashers off.
When the hazard warning flashers are on, your turn
signals will not work.
Other Warning Devices
If you carry reflective triangles, you can set them up at
the side of the road about 300 feet (100 m) behind
your vehicle.
Horn
Press near or on the horn symbols on your steering
wheel pad to sound the horn.
Tilt Wheel
Your vehicle has a tilt wheel which allows you to adjust
the steering wheel before you drive. You can raise it
to the highest level to give your legs more room when
you exit and enter the vehicle.
The tilt wheel lever is
located underneath the
steering column slightly
to the left.
To tilt the steering wheel, hold the wheel and push the
lever down. Then, move the wheel to a comfortable
position and pull the lever up to lock the wheel in place.

Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
•Turn and Lane-Change Signals. SeeTurn and
Lane-Change Signals on page 3-7.
•Headlamp High/Low-Beam Changer. SeeHeadlamp
High/Low-Beam Changer on page 3-8.
•Flash-to-Pass. SeeFlash-to-Pass on page 3-8.
•Exterior Light Control. SeeExterior Lamps on
page 3-13.
•Fog Lamps, if equipped. SeeFog Lamps on
page 3-15.
Turn and Lane-Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow you
to signal a turn or a lane change.
To signal a turn, move the lever all the way up or down.
When the turn is finished, the lever will return
automatically.
An arrow on the instrument
panel cluster will flash in
the direction of the
turn or lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts to flash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it.
As you signal a turn or a lane change, if the arrows
flash rapidly, a signal bulb may be burned out and other
drivers will not see your turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows do not go on at all when you
signal a turn, check for burned-out bulbs and then check
the fuse. SeeFuses and Circuit Breakers on page 5-75. Uplevel shown, Base similar

2. Accelerate to the speed you want.
3. Press the SET button and release it. The cruise
control light will come on to show you that the
cruise control is on.
4. Take your foot off the accelerate pedal.
Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake pedal, or the clutch
pedal if you have a manual transaxle. This, of course,
shuts off the cruise control. But you do not need to reset
it. Once you are going about 24 mph (39 km/h) or
more, you can briefly press the RESUME button.
You will go right back up to your chosen speed and
stay there.
If you hold in the RESUME button longer, the vehicle
will keep going faster until you release the button
or apply the brake pedal. So unless you want to go
faster, do not hold in the RESUME button.
