Never put a rear facing child restraint in the right
front passenger’s seat unless the airbag is off.
Here is why:
{CAUTION:
A child in a rear-facing child restraint
can be seriously injured or killed if the
right front passenger’s airbag inates.
This is because the back of the rear-facing
child restraint would be very close to the
inating airbag. Be sure the airbag is off
before using a rear-facing child restraint in
the right front seat position. If you secure a
forward-facing child restraint in the right
front seat, always move the right front
passenger seat as far back as it will go.
A rear seat is a safer place to secure a forward
facing child restraint. SeeWhere to Put the
Restraint on page 52. If you need to secure a
forward-facing child restraint in the right front seatposition, move the seat as far back as it will go
before securing a forward-facing child restraint. See
Manual Seats on page 9orPower Seat on page 10.
{CAUTION:
If the airbag readiness light in the
instrument panel cluster ever comes on
when you have turned off the airbag,
it means that something may be wrong
with the airbag system. The right front
passenger’s airbag could inate even
though the switch is off. If this ever
happens, have the vehicle serviced
promptly. Until you have the vehicle
serviced, do not let anyone whom the
national government has identied as a
member of a passenger airbag risk group
sit in the right front passenger’s position
(for example, do not secure a rear-facing
child restraint in the right front passenger’s
seat). SeeAirbag Off Switch on page 86.
74

{CAUTION:
When an airbag inates, there may be
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.
Your vehicle has a feature that may automatically
unlock the doors, turn the interior lamps on, and
turn the hazard warning flashers on when the
airbags inflate. You can lock the doors again, turn
the interior lamps off, and turn the hazard warning
flashers off by using the controls for those features.In many crashes severe enough to inflate an airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur
from the right front passenger airbag.•Airbags are designed to inflate only once.
After they inflate, you will need some new parts
for the airbag system. If you do not get them,
the airbag system will not be there to help
protect you in another crash. A new system
will include airbag modules and possibly other
parts. The service manual for your vehicle
covers the need to replace other parts.
•Your vehicle has a crash sensing and
diagnostic module which records information
after a crash. SeeVehicle Data Recording
and Privacy on page 441andEvent Data
Recorders on page 442.
•Let only qualified technicians work on the
airbag system. Improper service can mean
that an airbag system will not work properly.
See your dealer/retailer for service.
85

To turn off the right front passenger’s airbag,
insert your ignition key into the switch, push in,
and move the switch to the off position.
The airbag off light will come on to let you know
that the right front passenger’s airbag is off.
The light will stay on to remind you that the
airbag is off. The right front passenger’s airbag
will remain off until you turn it back on.
{CAUTION:
If the airbag readiness light ever comes
on when you have turned off the airbag,
it means that something may be wrong
with the airbag system. The right front
passenger’s airbag could inate even
though the switch is off. If this ever
happens, do not let anyone whom the
national government has identied as a
member of a passenger airbag risk group
sit in the right front passenger’s position
(for example, do not secure a rear-facing
child restraint in your vehicle) until
you have your vehicle serviced. See
Airbag Readiness Light on page 169
for additional information.

{CAUTION:
If the airbag readiness light in the
instrument panel cluster ever comes on
and stays on, it means that something may
be wrong with the airbag system. If this
ever happens, have the vehicle serviced
promptly, because an adult-size person
sitting in the right front passenger’s
seat may not have the protection of the
airbag(s). SeeAirbag Readiness Light
on page 169for more on this, including
important safety information.A thick layer of additional material, such as a
blanket or cushion, or aftermarket equipment such
as seat covers, seat heaters, and seat massagers
can affect how well the passenger sensing
system operates. You may want to consider not
using seat covers or other aftermarket equipment.
SeeAdding Equipment to Your Airbag-Equipped
Vehicle on page 97for more information about
modifications that can affect how the system
operates.
{CAUTION:
Stowing of articles under the passenger’s
seat or between the passenger’s seat
cushion and seatback may interfere with
the proper operation of the passenger
sensing system.
95

Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be
serviced. There are parts of the airbag system
in several places around your vehicle. You do
not want the system to inflate while someone is
working on your vehicle. Your dealer/retailer
and the service manual have information about
servicing your vehicle and the airbag system.
To purchase a service manual, seeService
Publications Ordering Information on page 440.
{CAUTION:
For up to 10 seconds, after the ignition is
turned off and the battery is disconnected,
an airbag can still inate during improper
service. You can be injured if you are
close to an airbag when it inates. Avoid
yellow connectors. They are probably part
of the airbag system. Be sure to follow
proper service procedures, and make sure
the person performing work for you is
qualied to do so.
The airbag system does not need regular
maintenance.
96

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the
exterior 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 424.
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 424.
Your dealer/retailer and the service manual
have information about the location of the airbag
sensors, sensing and diagnostic module and
airbag wiring.

Remote Keyless Entry (RKE)
System
If the vehicle has a Remote Keyless Entry (RKE)
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 interference.
2. This device must accept any interference
received, including interference that may
cause undesired operation of the device.
This device complies with RSS-210 of Industry
Canada. Operation is subject to the following
two conditions:
1. This device may not cause interference.
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 RKE 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 “Battery
Replacement” and “Resynchronization”
underRemote Keyless Entry (RKE) System
Operation on page 105.
•If you are still having trouble, see your
dealer/retailer or a qualified technician
for service.
104

Matching Transmitter(s) to Your
Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your
vehicle. If a transmitter is lost or stolen, a
replacement can be purchased through your
dealer/retailer. Remember to bring any remaining
transmitters with you when you go to your
dealer/retailer. When the dealer/retailer matches
the replacement transmitter to your vehicle,
any remaining transmitters must also be matched.
Once your dealer/retailer has coded the new
transmitter, the lost transmitter will not unlock your
vehicle. Each vehicle can have a maximum of
four transmitters matched to it.
Resynchronization
Resynchronization may be necessary due to the
security method used by this system. The
transmitter does not send the same signal twice to
the receiver. The receiver will not respond to a
signal that has been sent previously. This prevents
anyone from recording and playing back the
signal from the transmitter.To resynchronize your transmitter, stand close to
your vehicle and press and hold the lock and
unlock buttons on the transmitter at the same time
for seven seconds. The door locks should cycle
to confirm synchronization. If the locks do not
cycle, see your dealer/retailer for service.
Battery Replacement
Under normal use, the battery in your remote
keyless entry transmitter should last about
four years.
You can tell the battery is weak if the transmitter
won’t work at the normal range in any location.
If you have to get close to your vehicle before the
transmitter works, it’s probably time to change
the battery.
Notice:When replacing the battery, use
care not to touch any of the circuitry. Static
from your body transferred to these surfaces
may damage the transmitter.
106

Visor Vanity Mirror
You may have visor vanity mirrors, with or without
lamps. Lift the mirror cover to turn the lamps
on, if you have them.
Theft-Deterrent Systems
Vehicle theft is big business, especially in some
cities. Although your vehicle has a number of
theft-deterrent features, we know that nothing we
put on it can make it impossible to steal.
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 SECURITY light will
go off approximately five seconds after the key
is turned to RUN. SeeSecurity Light on page 183.
If the engine stalls and the SECURITY 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 SECURITY 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/retailer. Your vehicle is not
protected by Passlock
®at this time. You may
also want to check the fuse. SeeFuses and Circuit
Breakers on page 393. See your dealer/retailer
for service.
Do not leave the key or device that disarms
or deactivates the theft deterrent system in
the vehicle.
