2005 GMC Envoy XUV Owner ManualM

In many crashes severe enough to inate an airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from
the right front passenger airbag.
Airbags are designed to inate only once. After an
airbag inates, you will need some new parts for your
airbag system. If you do not get them, the airbag
system will not be there to help protect you in another
crash. A new system will include airbag modules and
possibly other parts. The service manual for your
vehicle covers the need to replace other parts.
Your vehicle is equipped with a crash sensing and
diagnostic module which records information after a
crash. SeeVehicle Data Collection and Event Data
Recorders on page 7-9.
Let only qualied technicians work on your airbag
system. Improper service can mean that your airbag
system will not work properly. See your dealer
for service.Notice:If you damage the covering for the driver’s
or the right front passenger’s airbag, or the side
impact airbag covering on the ceiling near the side
windows, the airbag may not work properly.
You may have to replace the airbag module in the
steering wheel, both the airbag module and the
instrument panel for the right front passenger’s
airbag, or side impact airbag module and ceiling
covering for the roof-mounted side impact airbag.
Do not open or break the airbag coverings.

{CAUTION:
If the airbag readiness light in the instrument
panel cluster ever comes on and stays on,
it means that something may be wrong with
the airbag system. If this ever happens, have
the vehicle serviced promptly, because an
adult-size person sitting in the right front
passenger’s seat may not have the protection
of the frontal airbag. SeeAirbag Readiness
Light on page 3-34for more on this, including
important safety information.Aftermarket equipment, such as seat covers, can affect
how well the passenger sensing system operates.
You may want to consider not using seat covers or other
aftermarket equipment if your vehicle has the passenger
sensing system. SeeAdding Equipment to Your
Airbag-Equipped Vehicle on page 1-60for more
information about modications that can affect how the
system operates.
{CAUTION:
Stowing of articles under the passenger’s seat
or between the passenger’s seat cushion and
seatback may interfere with the proper
operation of the passenger sensing system.

Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are airbag system parts in several places around
your vehicle. You do not want the system to inate
while someone is working on your vehicle. Your dealer
and the service manual have information about
servicing your vehicle and the airbag system. To
purchase a service manual, seeService Publications
Ordering Information on page 7-11.
{CAUTION:
For up to 10 seconds after the ignition key 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.
The airbag system does not need regular maintenance.
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, front end or side sheet
metal or height, 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.

1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired

to your vehicle for the transmitter to work, try this:
Check the distance. You may be too far from your
vehicle. You may need to stand closer during
rainy or snowy weather.
Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
Check to determine if battery replacement is
necessary. See “Battery Replacement” under
Remote Keyless Entry System Operation on
page 2-6.
If you are still having trouble, see your dealer or a
qualied technician for service.

3. Clip the second row safety belts into the retainers.
They are mounted on the pillars below where the
safety belt passes through the trim panel. This
prevents the safety belt from being tangled in the
midgate when opening or closing the midgate.
4. Press the midgate release button located on the
driver’s side of the midgate while pulling the
release handle.
5. Lower the midgate and secure it in the down
position by engaging the midgate to the oor
support. The latch for the oor support is found on
the driver’s side of the vehicle.
Raising the Midgate
To return the midgate to its normal position, release the
midgate by pulling up on the lever found on the
driver’s side midgate support. Reverse the steps for
lowering the midgate listed previously. The midgate
must be fully latched on both sides before the midgate
glass can be raised.
Tailgate
Your vehicle is equipped with a tailgate which can be
swung out or opened at. It can be locked and unlocked
with the driver or passenger door power lock button
or the remote keyless entry transmitter. The tailgate has
power rear glass. The glass must be fully lowered to
open the tailgate to its at position.
The power roof and tailgate must both be fully closed to
raise the rear glass. If the roof or tailgate are not fully
closed, the words CLOSE THE ROOF or CLOSE
THE TAILGATE will appear on the DIC when you try
to raise the rear glass.
If the tailgate drop/swing, power roof, rear wiper and
rear window defogger functions are inoperative, or
SEE MANUAL– TAILGATE is displayed on the Driver
Information Center, the tailgate window position needs to
be reset. To reset the window position, activate the
tailgate window up switch and continue to hold it
for two seconds after the window is fully closed.
Then activate the tailgate window down switch and
continue to hold it for two seconds after the window is
fully open. If this process does not restore function,
see your dealer for service.

When a roof operation is halted because of an
obstruction such as ice, snow or an object in the
opening, the words CLEAR ROOF OBSTRUCTION will
appear on the DIC. Clear the roof obstruction and
then operate the roof.
Notice:If you attempt to operate the power roof
when it is frozen or blocked by ice or snow, you may
damage the power roof mechanism. Do not attempt
to operate the power roof when it is frozen or
blocked by ice or snow.
For information on cleaning the roof track, seeCleaning
the Roof Track on page 5-89.
Using the Tailgate Key Cylinder
To operate the power roof using the tailgate key
cylinder, the rear glass must be fully lowered. Turn and
hold the key clockwise to lower the rear glass. Once
the glass is completely lowered, the roof may be opened
by returning the key to the neutral (vertical) position
and then turning and holding the key clockwise again.
The roof may be closed by turning and holding the
key counterclockwise. Maintain the key in the
counterclockwise position until the roof is fully closed.
Resetting the Roof Position
The words OPEN THE ROOF may appear on the DIC.
This indicates a need to reset the roof position.
When this message appears, place the vehicle in
PARK (P) and the ignition in RUN or ACCESSORY.
Open the power roof using the power roof switch in
the overhead console. When the roof has fully opened,
the words CLOSE THE ROOF will appear and a
chime will sound. This completes the rst step of the
roof reset process.
With the vehicle still in PARK (P) and the ignition in
RUN or ACCESSORY, close the power roof using the
power roof switch in the overhead console until the
words ROOF IS CLOSED appear and a chime sounds.
If the words ROOF IS CLOSED do not appear within
one minute or the roof does not operate after this reset
process, see your dealer for service.
Resetting the Rear Glass Position
The words TAILGATE — SEE MANUAL may appear
on the DIC after the rear glass has been fully lowered
and the roof has not moved. Although this message
may appear when you attempt to operate the roof,
it indicates a need to reset the rear glass position.

If a locked door is opened without the key or the remote
keyless entry transmitter, the alarm will go off. The
headlamps and parking lamps will ash for two minutes,
and the horn will sound for 30 seconds, then will turn
off to save the battery power.
Remember, the theft-deterrent system won’t activate
if you lock the doors with a key or use the manual door
lock. It activates only if you use a power door lock
switch with the door open, or with the remote keyless
entry transmitter. You should also remember that
you can start your vehicle with the correct ignition key
if the alarm has been set off.
Here’s how to avoid setting off the alarm by accident:
If you don’t want to activate the theft-deterrent
system, the vehicle should be locked with the door
keyafterthe doors are closed.
Always unlock a door with a key, or use the remote
keyless entry transmitter. Unlocking a door any
other way will set off the alarm.
If you set off the alarm by accident, unlock any door
with the key. You can also turn off the alarm by
pressing unlock on the remote keyless entry transmitter.
The alarm won’t stop if you try to unlock a door any
other way.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver’s window
and open the driver’s door.
2. Activate the system by locking the doors with the
power door lock switch while the door is open, or
with the remote keyless entry transmitter.
3. Get out of the vehicle, close the door and wait for
the security light to go out.
4. Then reach in through the window, unlock the door
with the manual door lock and open the door.
This should set off the alarm.
When the alarm is set the power door unlock switch is
not operational.
If the alarm does not sound when it should but the
headlamps ash, check to see if the horn works.
The horn fuse may be blown. To replace the fuse,
seeFuses and Circuit Breakers on page 5-97.
If the alarm does not sound or the headlamps do not
ash, the vehicle should be serviced by your dealer.
