2009 GMC Envoy and Envoy Denali Owner ManualM

Passenger Sensing System
The vehicle has a passenger sensing system for the right
front passenger position. The passenger airbag status
indicator will be visible in the rearview mirror when the
vehicle is started.
The words ON and OFF, or the symbol for on and off, will
be visible during the system check. When the system
check is complete, either the word ON or OFF, or the
symbol for on or off, will be visible. SeePassenger Airbag
Status Indicator on page 3-32.The passenger sensing system will turn off the right
front passenger frontal airbag under certain conditions.
The driver airbags and roof-rail airbags are not
affected by the passenger sensing system.
The passenger sensing system works with sensors that
are part of the right front passenger seat. The sensors
are designed to detect the presence of a properly-seated
occupant and determine if the right front passenger
frontal airbag should be enabled (may inate) or not.
According to accident statistics, children are safer when
properly secured in a rear seat in the correct child
restraint for their weight and size.
We recommend that children be secured in a rear seat,
including: an infant or a child riding in a rear-facing
child restraint; a child riding in a forward-facing child
seat; an older child riding in a booster seat; and children,
who are large enough, using safety belts.
A label on the 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. United States

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, rearview mirror, front 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,
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 1-64.
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 5-72
for additional important information.
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. SeeCustomer
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.

Press
Oor depending on the mirror, press COMP to
turn the compass on or off.
Compass Calibration
The compass may need calibration if:
After several seconds, the display does not show a
compass heading (N for North, for example), there
may be a strong magnetic eld interfering with
the compass. Interference can be caused by
a magnetic antenna mount, magnetic note pad
holder or a similar magnetic item.
The compass does not display the correct heading
and the compass zone variance is set correctly.
In order to calibrate, CAL must be displayed in the
mirror compass windows. If CAL is not displayed, press
and hold
Oor depending on the mirror, press COMP
until CAL displays.
The compass can be calibrated by driving the vehicle in

will also come on when this mode is activated. While in
recirculation mode, the windows may fog when the
weather is cold and damp. To clear the fog, select either
the defog or defrost mode and increase fan speed.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<(Rear):Press to turn the rear window defogger on
or off. An indicator light in the button comes on to
show that the rear window defogger is on. The rear
window defogger automatically turns off approximately
ten minutes after the button is pressed.
For vehicles with heated mirrors, they turn on when the
rear window defogger button is pressed.
Notice:Do not use anything sharp on the inside
of the rear window. If you do, you could cut or
damage the warming grid, and the repairs would not
be covered by the vehicle warranty. Do not attach
a temporary vehicle license, tape, a decal or
anything similar to the defogger grid.
