WARNING:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front passenger
airbag inflates. This is because the back of the
rear-facing child restraint would be very close to the
inflating airbag. A child in a forward-facing child
restraint can be seriously injured or killed if the right
front passenger airbag inflates and the passenger
seat is in a forward position.
Even if the passenger sensing system has turned
off the right front passenger frontal airbag, no
system is fail-safe. No one can guarantee that
an airbag will not deploy under some unusual
circumstance, even though the airbag is turned off.
Secure rear-facing child restraints in a rear
seat, even if the airbag is off. If you secure a
forward-facing child restraint in the right front seat,
always move the front passenger seat as far back
as it will go. It is better to secure the child restraint in
a rear seat.The passenger sensing system is designed to turn off
the right front passenger frontal airbag if:
•
The right front passenger seat is unoccupied.
•
The system determines that an infant is present in
a child restraint.
•
A right front passenger takes his/her weight off of
the seat for a period of time.
•
Or, if there is a critical problem with the airbag
system or the passenger sensing system.
When the passenger sensing system has turned off the
right front passenger frontal airbag, the off indicator
will light and stay lit to remind you that the airbag is off.
SeePassenger Airbag Status Indicator on page 4-25.
2-67

If the On Indicator is Lit for a Child
RestraintIf a child restraint has been installed and the on
indicator is lit:
1. Turn the vehicle off.
2. Remove the child restraint from the vehicle.
3. Remove any additional items from the seat such as
blankets, cushions, seat covers, seat heaters, or
seat massagers.
4. Reinstall the child restraint following the directions
provided by the child restraint manufacturer and
refer toSecuring a Child Restraint in the Right Front
Seat Position on page 2-52.5. If, after reinstalling the child restraint and restarting
the vehicle, the on indicator is still lit, turn the
vehicle off. Then slightly recline the vehicle seatback
and adjust the seat cushion, if adjustable, to
make sure that the vehicle seatback is not pushing
the child restraint into the seat cushion.
Also make sure the child restraint is not trapped
under the vehicle head restraint. If this happens,
adjust the head restraint. SeeHead Restraints
on page 2-2.
6. Restart the vehicle.
The passenger sensing system may or may not turn off
the airbag for a child in a child restraint depending
upon the child’s seating posture and body build. It is
better to secure the child restraint in a rear seat.

Adding Equipment to Your
Airbag-Equipped VehicleQ:
Is there anything I might add to or change
about the vehicle that could keep the airbags
from working properly?
A:
Yes. If you add things that change the vehicle’s
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system from
working properly. Changing or moving any parts
of the front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel, instrument
panel, roof-rail airbag modules, ceiling headliner
or pillar garnish trim, front sensors, side impact
sensors, or airbag wiring can affect the operation of
the airbag system.
In addition, the vehicle has a passenger sensing
system for the right front passenger position, which
includes sensors that are part of the passenger’s
seat. The passenger sensing system may not
operate properly if the original seat trim is replaced
with non-GM covers, upholstery or trim, or with
GM covers, upholstery or trim designed for a
different vehicle. Any object, such as an aftermarket
seat heater or a comfort enhancing pad or device,
installed under or on top of the seat fabric,could also interfere with the operation of the
passenger sensing system. This could either
prevent proper deployment of the passenger
airbag(s) or prevent the passenger sensing system
from properly turning off the passenger airbag(s).
SeePassenger Sensing System on page 2-66.
If you have any 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 8-2.
Q:
Because I have a disability, I have to get
my vehicle modified. How can I find out whether
this will affect my airbag system?
A:
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. See
Customer Satisfaction Procedure on page 8-2.
In addition, your dealer/retailer and the service manual
have information about the location of the airbag
sensors, sensing and diagnostic module and airbag
wiring.

III+ Electronic
Immobilizer Operation
Your vehicle has PASS-Key
®III+ (Personalized
Automotive Security System) theft-deterrent system.
PASS-Key
®III+ is a passive theft-deterrent system.
The system is automatically armed when the key
is removed from the ignition.
The system is automatically disarmed when the key is
turned to ON/RUN, ACC/ACCESSORY or START
from the LOCK/OFF position.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problem
with arming or disarming the theft-deterrent system.When the PASS-Key
®III+ system senses that someone
is using the wrong key, it prevents the vehicle from
starting. Anyone using a trial-and-error method to start
the vehicle will be discouraged because of the high
number of electrical key codes.
If the engine does not start and the security light on the
instrument panel cluster comes on when trying to
start the vehicle, there may be a problem with your
theft-deterrent system. Turn the ignition off and try again.
If the engine still does not start, and the key appears
to be undamaged, try another ignition key. At this time,
you may also want to check the fuse, seeFuses
and Circuit Breakers on page 6-96. If the engine still
does not start with the other key, your vehicle needs
service. If your vehicle does start, the first key may be
faulty. See your dealer/retailer who can service the
PASS-Key
®III+ to have a new key made. In an
emergency, contact Roadside Assistance.
It is possible for the PASS-Key
®III+ decoder to learn
the transponder value of a new or replacement key.
Up to 10 keys may be programmed for the vehicle.
The following procedure is for programming additional
keys only. If all the currently programmed keys are
lost or do not operate, you must see your dealer/retailer
or a locksmith who can service PASS-Key
®III+ to
have keys made and programmed to the system.
