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.

1-31
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 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 15 seconds 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 wires wrapped with yellow tape
or 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.

Remote Keyless Entry System
(If Equipped)
If your vehicle has this feature, you can lock and unlock
your doors from about 3 feet (1 m) up to 30 feet (9 m)
away using the remote keyless entry transmitter supplied
with your vehicle.
Your remote keyless entry system operates on a radio
frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference,
and (2) this device must accept any interference
received, including interference that may cause
undesired operation.
This device complies with RSS
-210 of Industry Canada.
Operation is subject to the following two conditions:
(1) this device may not cause interference, and (2) this
device must accept any interference received, including
interference that may cause undesired operation of
the device.Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:

Check the distance. You may be too far from your
vehicle. You may need to stand closer during rainy
or snowy weather.

Check the location. Other vehicles or objects may be
blocking the signal. Take a few steps to the left or
right, hold the transmitter higher, and try again.

Check to determine if battery replacement or
resynchronization is necessary. See the instructions
that follow.

If you're still having trouble, see your dealer or a
qualified technician for service.

2-13
To replace the battery in the transmitter do the following:
1. Use a coin or similar object to separate the bottom
half from the top half of the transmitter.
2. Remove the battery and replace it with the new one.
Make sure the positive side of the battery faces
down. For battery replacement, use a 3
-volt battery,
type CR2032 or equivalent.
3. Read the instructions inside the case.
4. Put the two halves back together. Make sure the
cover is on tight so water won't get in.
5. Check the operation of the transmitter with your
vehicle. If the transmitter does not work, try
resynchronizing the transmitter with the receiver.
See ªResynchronizationº following.
Resynchronization
Your remote keyless entry system is equipped with a
security system that prevents anyone from recording and
playing back your signal. The transmitter does not send
the same signal twice to the receiver. The receiver will
not respond to a signal that has been sent to it more
than once.
To resynchronize your transmitter and receiver, follow
these directions:
1. Stand close to your vehicle.
2. Press and hold the LOCK and UNLOCK buttons
on the transmitter at the same time.
3. Hold the buttons for at least seven seconds.
During this time, the doors should lock and
unlock once. This confirms the resynchronization.
If the doors do not lock and unlock, see your dealer
for service.

2-16
Ignition Positions
With the key in the ignition
switch, you can turn it to
four different positions.
LOCK (A): This is the only position from which you
can remove the key. This position locks your steering
wheel, ignition and automatic transmission.
If you have an automatic transmission, the ignition
switch can't be turned to LOCK unless the shift lever
is in PARK (P).CAUTION:
On manual transmission vehicles, turning the key
to LOCK 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. Don't push the key in while the vehicle
is moving.
NOTICE:
If your key seems stuck in LOCK and you can't
turn it, be sure you are using the correct key;
if so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the
key hard. Turn the key only with your hand.
Using a tool to force it could break the key or
the ignition switch. If none of this works, then
your vehicle needs service.

2-69 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 modules, 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 vehicle,
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
vehicle or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inflate in a crash, or they
could even inflate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the air bag readiness light
stays on after you start your vehicle.
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.

2-71
United States Canada
This light should come on when you turn the ignition
key to START. If it doesn't come on then, have it fixed
so it will be ready to warn you if there's a problem.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the floor.
It may take longer to stop. If the light is still on, have
the vehicle towed for service. See ªAnti
-Lock Brake
System Warning Lightº and ªTowing Your Vehicleº in
the Index.
CAUTION:
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident. If the light is still on after you've
pulled off the road and stopped carefully, have
the vehicle towed for service.

2-72 Anti-Lock Brake System Warning
Light (Option)
With the anti-lock brake
system, this light will
come on when you start
your engine and it will
stay on for three seconds.
That's normal.
If the light comes on when you're driving, you don't
have anti
-lock brakes and there could be a problem with
your regular brakes. Pull off the road and stop carefully.
You may notice that the pedal is harder to push. Or, the
pedal may go closer to the floor. It may take longer to
stop. Have the vehicle towed for service. See ªTowing
Your Vehicleº in the Index.
CAUTION:
Your regular brake system may not be working
properly if the anti
-lock brake system warning
light is on. Driving with the anti
-lock brake
system warning light on can lead to an accident.
After you've pulled off the road and stopped
carefully, have the vehicle towed for service.
If the anti-lock brake system warning light stays on
longer than normal after you've started your engine,
turn the ignition off. Or, if the light comes on and stays
on when you're driving, stop as soon as possible and
turn the ignition off. Then start the engine again to reset
the system. If the light still stays on, or comes on again
while you're driving, your vehicle needs service. If the
light is on and the regular brake system warning light
isn't on, you still have brakes, but you don't have
anti
-lock brakes.
The anti
-lock brake system warning light should come
on briefly 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.

2-73 Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature. If the
gage pointer moves to the
H (red) side, your engine
is too hot.
It means that your engine coolant has overheated and
you should stop your vehicle and turn off the engine
as soon as possible.
The ªProblems on the Roadº section of this manual
shows what to do. See ªEngine Overheatingº in
the Index.
Malfunction Indicator Lamp
(Service Engine Soon Light)
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD II (On
-Board
Diagnostics
-Second Generation) and is intended to
assure that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment. The SERVICE ENGINE SOON light
comes on to indicate that there is a problem and service
is required. Malfunctions often will be indicated by the
system before any problem is apparent. This may
prevent more serious damage to your vehicle.
This system is also designed to assist your service
technician in correctly diagnosing any malfunction.

2-74
NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
NOTICE:
Modifications made to the engine, transmission,
exhaust, intake or fuel system of your vehicle or
the replacement of the original tires with other
than those of the same Tire Performance Criteria
(TPC) can affect your vehicle's emission controls
and may cause the SERVICE ENGINE SOON
light to come on. Modifications to these systems
could lead to costly repairs not covered by your
warranty. This may also result in a failure to pass
a required Emission Inspection/Maintenance test.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running. If the light doesn't come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:

Light Flashing
-- A misfire condition has been
detected. A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service may be required.

Light On Steady
-- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.
