1-27
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.

1-28 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 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.
Rear Seat Passengers
It's very important for rear seat passengers to buckle up!
Accident statistics show that unbelted people in the rear
seat are hurt more often in crashes than those who are
wearing safety belts.
Rear passengers who aren't safety belted can be thrown
out of the vehicle in a crash. And they can strike others
in the vehicle who are wearing safety belts.

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.

2-12 Replacing the Battery in the Remote
Keyless Entry System Transmitter
To replace the battery in the transmitter:
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 three
-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 tightly, 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.
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.
Normally, the transmitter and receiver resynchronize
automatically. However, under certain circumstances,
manual resynchronization may be required.
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 10 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.

2-18 How to Turn Off the System Alarm
If the system alarm is active, it can be deactivated by:

Pressing the transmitter LOCK or panic button to
turn
-off alarm. The system will also rearm if all
doors and trunk are later closed, or

pressing the transmitter UNLOCK or trunk button to
turn off the alarm and disarm system, or

putting the key in the ignition and turning it to
START to turn off the alarm and disarm the system.
How to Detect a Tamper Condition
If you hear three horn chirps when you press the
UNLOCK, LOCK or trunk buttons on your transmitter,
that means the content theft security system alarm was
triggered while you were away.
Your dealer can change the settings to disable the
headlamp flash and horn chirp features. Your dealer can
also change the settings to allow the horn to chirp twice
on the first press of the UNLOCK button. See your
dealer for more information.
Passlock
Your vehicle is equipped with the Passlock
theft
-deterrent system.
Passlock is a passive theft
-deterrent system. Passlock
enables fuel if the ignition lock cylinder is turned with a
valid key. If a correct key is not used or the ignition lock
cylinder is tampered with, fuel is disabled.
During normal operation, the THEFT SYSTEM light
will go off approximately five seconds after the key
is turned to the RUN ignition position following an
engine start.
If the engine stalls and the THEFT SYSTEM light
flashes, wait until the light stops flashing before trying
to restart the engine. Remember to release the key from
START as soon as the engine starts.
If the engine is running and the THEFT SYSTEM light
comes on, you will be able to restart the engine if you
turn the engine off. However, your Passlock system is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by Passlock at this
time. You may also want to check the fuses (See ªFuses
and Circuit Breakersº in the Index). See your dealer for
service. Also, see ªRoadside Assistanceº in the Index
for more information.

B (LOCK): This position locks your steering wheel,
ignition, shift lever and transaxle. This is the only
position from which you can remove the key. A warning
chime will sound if you open the driver's door when the
ignition is in LOCK and the key is in the ignition.
CAUTION:
On manual transaxle 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 OFF. Don't press the key release button 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.
C (OFF): This position unlocks the steering wheel,
ignition and transaxle, but does not send power to any
accessories. Use this position if your vehicle must be
pushed or towed, but never try to push
-start your
vehicle. A warning chime will sound if you open the
driver's door when the ignition is in OFF and the key
is in the ignition.

This indicator light on
your instrument panel
cluster will come on
when the DRL are on.
A flashing DRL telltale indicates a possible burned out
headlamp, or that the vehicle may need service to repair
a stuck DRL relay.
When the DRL are on, your high and low
-beam
headlamps will be on at a reduced brightness. The
taillamps, sidemarker and other lamps won't be on. Your
instrument panel won't be lit up either.
When you turn the exterior lamp band to the headlamp
position, your high and low
-beam headlamps will go out, and
your low
-beam headlamps will come on. The other lamps
that come on with your headlamps will also come on.
When you turn off the headlamps, the regular lamps will
go off, and your high and low
-beam headlamps will
come on to the reduced brightness.
To idle your vehicle with the DRL off, set the parking
brake. The DRL 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.
Fog Lamps (If Equipped)
Use your fog lamps for better vision in foggy or
misty conditions.
The button for your fog
lamps is located next to
the instrument panel
brightness control.
Push the top of the button to turn the fog lamps on. Push
the top of the button again to turn the fog lamps off.
When using fog lamps, the parking lamps or low
-beam
headlamps must be on.
A light on the button will come on when the fog lamps
are actually on. Fog lamps will go off whenever the
high
-beam headlamps come on. When the high-beam
headlamps go off, the fog lamps will come on again.

2-62 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 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 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.
