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, 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,
installed under or on top of the seat fabric, could alsointerfere 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 1-63.
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: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.

Key In the Ignition
Never leave your vehicle with the keys inside, as it is an
easy target for joy riders or thieves. If you leave the
key in the ignition and park your vehicle, a chime
will sound, when you open the driver’s door. Always
remember to remove your key from the ignition and take
it with you. This will lock your ignition and transmission.
Also, always remember to lock the doors.
The battery could be drained if you leave the key in the
ignition while your vehicle is parked. You may not be
able to start your vehicle after it has been parked for an
extended period of time.
Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
10 minutes after the ignition key is turned off:
Audio System

Sunroof (if equipped)Power to these accessories will work up to 10 minutes
or until the driver’s door is opened. For an additional
10 minutes of power, close all the doors and turn the key
to ON/RUN and then back to LOCK/OFF.
Starting the Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position – this
is a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
2-24

Sunroof
The vehicle may have a power sunroof.
The switches that operate
the sunroof are located on
the overhead console.
To open or close the sunroof, the ignition must be
turned to ON/RUN or Retained Accessory Power (RAP)
must be active. SeeRetained Accessory Power
(RAP) on page 2-24.Express Open:The express open feature will operate
from the closed or partially open position. To express
open the power sunroof, fully press the driver’s
side switch rearward once. To stop the sunroof glass in
a desired position other than to the express-open
position, press the switch again, in either direction, to
stop the movement. If the sunshade is in the closed
position, it will open with the sunroof, or it can be
opened manually.
Vent Open:From the closed position, press and hold the
passenger’s side switch forward to vent the sunroof. The
rear of the sunroof panel will tilt upward to the full vent
position. The sunshade must be opened manually.

XM™ Satellite Radio Service
XM Satellite Radio Service gives digital radio reception
from coast-to-coast in the 48 contiguous United
States, and in Canada. Just as with FM, tall buildings
or hills can interfere with satellite radio signals, causing
the sound to fade in and out. In addition, traveling or
standing under heavy foliage, bridges, garages, or
through tunnels could cause loss of the XM signal for a
period of time. The radio may display NO XM SIGNAL
to indicate interference.
Backglass Antenna
The AM-FM antenna is integrated with the rear window
defogger, located in the rear window. Make sure that
the inside surface of the rear window is not scratched
and that the grid lines on the glass are not damaged.
If the inside surface is damaged, it could interfere
with radio reception.
Notice:Using a razor blade or sharp object to clear
the inside rear window may damage the rear window
antenna and/or the rear window defogger. Repairs
would not be covered by your warranty. Do not clear
the inside rear window with sharp objects.
Notice:Do not apply aftermarket glass tinting with
metallic lm. The metallic lm in some tinting
materials will interfere with or distort the incomingradio reception. Any damage caused to your
backglass antenna due to metallic tinting materials
will not be covered by your warranty.
If static is heard on the radio, when the rear window
defogger is turned on, it could mean that a defogger
grid line has been damaged. If this is true, the grid line
must be repaired.
If adding a cellular telephone to your vehicle, and the
antenna needs to be attached to the glass, make
sure that the grid lines for the AM-FM antenna are not
damaged. There is enough space between the grid lines
to attach a cellular telephone antenna without interfering
with radio reception.
XM™ Satellite Radio Antenna
System
The XM™ Satellite Radio antenna is located on the roof
of the vehicle. Keep this antenna clear of snow and
ice build up for clear radio reception.
If the vehicle has a sunroof, the performance of the
XM system may be affected if the sunroof is open.
Loading items onto the roof of the vehicle can interfere
with the performance of the XM system. Make sure
the XM Satellite Radio antenna is not obstructed.
