Air Bag Readiness Light
There is an air bag readiness light on the secondary
information center (SIC), 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, seeAir Bag Systems
on page 1-50.
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 or flashes 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 inate in a crash, or they
could even inate 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 to ON. If the light
does not come on then, have it fixed so it will be ready
to warn you if there is a problem.

The passenger sensing system works with a sensor
that is part of the right front passenger’s seat cushion.
The sensor is designed to detect the presence of a
properly-seated occupant and determine if the
passenger’s frontal airbag and side impact airbag
(if equipped) should be enabled (may inflate) or not.
Accident statistics show that children are safer if
they are restrained in the rear, rather than the front
seat. General Motors recommends that child restraints
be secured in a rear seat, including an infant riding
in a rear-facing infant seat, a child riding in a
forward-facing child seat, and an older child riding in a
booster seat.
Your vehicle has a rear seat that will accommodate a
rear-facing child restraint. A label on your sun visor says,
“Never put a rear-facing child seat in the front.” This
is because the risk to the rear-facing child is so great,
if the airbag deploys.
{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.
Even though the passenger sensing system is
designed to turn off the passenger’s frontal
airbag and side airbag (if equipped) if the
system detects a rear-facing child restraint, no
system is fail-safe, and no one can guarantee
that an airbag will not deploy under some
unusual circumstance, even though it is turned
off. General Motors recommends that
rear-facing child restraints be secured in the
rear seat, even if the airbag or airbags are off.
If you need to 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.

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.

Clock
Your vehicle has a digital clock. The clock is located in
the secondary instrument cluster on the center of
the instrument panel, above the center air outlets. When
the ignition is turned to ACC or ON, the time is
displayed in the digital clock. There are two adjusting
buttons for the digital clock:
H (Hour):To go forward one hour, press the H button
once. To go forward more than one hour, press and hold
the button until the correct hour is reached.
M (Minute):To go forward one minute, press the
M button once. To go forward more than one minute,
press and hold the button until the correct minute
is reached.
After disconnecting the battery or replacing the fuse,
reset the clock.
Safety Belt Reminder Light
The safety belt light will
come on and stay on until
the driver’s safety belt
is buckled.
If the driver’s belt is already buckled, the light will not
come on.
Airbag Readiness Light
There is an airbag readiness light on the secondary
information center (SIC), which shows the airbag
symbol. The system checks the airbag’s electrical
system for malfunctions. The light tells you if there is an
electrical problem. The system check includes the
airbag sensor, the airbag modules, the wiring and the
crash sensing and diagnostic module. For more
information on the airbag system, seeAirbag System on
page 1-56.
