Servicing Your Airbag-Equipped
Vehicle
Airbags affect how the vehicle should be serviced.
There are parts of the airbag system in several places
around the vehicle. Your dealer/retailer and the
service manual have information about servicing the
vehicle and the airbag system. To purchase a service
manual, seeService Publications Ordering Information
on page 7-15.
{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.
Adding Equipment to Your
Airbag-Equipped Vehicle
Q: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 your 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, overhead console, front
sensors, side impact sensors, rollover sensor
module, or airbag wiring can affect the operation of
the airbag system.
In addition, your vehicle has a passenger sensing
system for the right front passenger’s 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,
1-96

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 1-90.
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.
If your vehicle has rollover roof-rail airbags, see
Different Size Tires and Wheels on page 5-80
for additional important information.Q:What if I added a snow plow? Will it keep the
airbags from working properly?
A:We have designed our airbag systems to work
properly under a wide range of conditions,
including snow plowing with vehicles that have the
optional Snow Plow Prep Package (RPO VYU).
But do not change or defeat the snow plow’s
“tripping mechanism.” If you do, it can damage your
snow plow and your vehicle, and it may cause an
airbag ination.
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: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 7-2.
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.

Retained Accessory Power (RAP)
The following vehicle accessories can be used for up to
10 minutes after the engine is turned off:
Audio System
Power Windows
OnStar®System (if equipped)
Sunroof (if equipped)
These features work when the key is in ON/RUN or

2-28

Center Console Storage
For vehicles with a console compartment, it is located
between the bucket seats.
Press the button and lift the lid to access the console
compartment.
A cupholder located in the rear of the console, swings
down for the rear seat passenger to use.
Luggage Carrier
Notice:Loading cargo on the luggage carrier that
weighs more than 200 lbs (91 kg) or hangs over the
rear or sides of the vehicle can damage the vehicle.
Load cargo so that it rests on the slats as far forward
as possible and against the side rails, making sure to
fasten it securely.
For vehicles with a luggage carrier, items can be loaded
on top of the vehicle.
The luggage carrier has siderails attached to the roof.
It can also have crossrails which can be moved
back and forth to help secure cargo. Tie the load
to the siderails or siderail supports.
Do not exceed the maximum vehicle capacity when
loading the vehicle. For more information on vehicle
capacity and loading, seeLoading the Vehicle on
page 4-33.
Make sure the cargo is properly loaded.To prevent damage or loss of cargo while driving,
periodically stop and check to make sure cargo is still
securely fastened.
If small heavy objects are placed on the roof, cut a
piece of 3/8 inch plywood to t inside the crossrails
and siderails to spread the load. Tie the plywood
to the siderail supports.
Tie the load and secure it to the crossrails or the
siderail supports. Use the crossrails only to keep
the load from sliding. To move a crossrail, lift
the release lever up, on both sides of the rail.
Then slide the crossrail to the desired position
balancing the force side to side. Press the release
lever down on both sides of the rail, down to
tighten it. Try to slide the crossrail back and forth
slightly to make sure it is tight.
To carry long items, move the crossrails as far apart
as possible. Tie the load to the crossrails and the
siderails or siderail supports. Also tie the load to the
bumpers, but do not tie the load so tightly that the
crossrails or siderails are damaged.
After moving a crossrail, be sure it is securely locked
into the siderail.
A Center High-Mounted Stoplamp (CHMSL) is located
above the rear window glass.
Make sure items loaded on the roof of the vehicle do
not block or damage the CHMSL.

To put the cover in the vehicle:
1. Make sure the cover slot in the holder faces
rearward with the round surface facing down.
2. Then, hold the cover at an angle and place the
cover end cap into the slot in the passenger side
trim panel.
3. Move the other end of the cover forward and hold it
next to the driver’s side trim panel slot.
4. Press the end caps in, to allow the cover to t into
the trim slot.
5. Pull lightly on the cover holder to make sure it is
secure.
On extended wheelbase models there are two
cover positions. The slots furthest forward allow the
cover to be used if the third seat is removed or
folded down. The cover can be installed and
removed from either side.Sunroof
Your vehicle may be equipped with a power sliding
sunroof. To open or close the sunroof, the ignition needs
to be turned to ON/RUN, or Retained Accessory Power
(RAP) must be active. When RAP is active, the sunroof
will work for 10 minutes after the ignition is turned off, or
