2007 GMC ENVOY seats

A booster seat (F-G) is a child restraint designed
to improve the t of the vehicle’s safety belt
system. Some booster seats have a shoulder belt
positioner, and some high-back booster seats
have a ve-point harness. A booster seat can also
help a child to see out the window.
Q:How Should I Use a Child Restraint?
A:A child restraint system is any device designed
for use in a motor vehicle to restrain, seat,
or position children. A built-in child restraint
system is a permanent part of the motor
vehicle. An add-on child restraint system is
a portable one, which is purchased by
the vehicle’s owner. To help reduce injuries,
an add-on child restraint must be secured
in the vehicle. With built-in or add-on
child restraints, the child has to be secured
within the child restraint.
When choosing an add-on child restraint,
be sure the child restraint is designed to
be used in a vehicle. If it is, it will have a label
saying that it meets federal motor vehicle
safety standards. Then follow the instructions
for the restraint. You may nd these
instructions on the restraint itself or in a
booklet, or both.

Securing an Add-on Child Restraint in
the Vehicle
{CAUTION:
A child can be seriously injured or killed
in a crash if the child restraint is not
properly secured in the vehicle. Make sure
the child restraint is properly installed in
the vehicle using the vehicle’s safety
belt or LATCH system, following the
instructions that came with that restraint,
and also the instructions in this manual.
To help reduce the chance of injury, the child
restraint must be secured in the vehicle.
Child restraint systems must be secured in vehicle
seats by lap belts or the lap belt portion of a
lap-shoulder belt, or by the LATCH system.SeeLower Anchors and Tethers for Children
(LATCH) on page 56for more information. A
child can be endangered in a crash if the child
restraint is not properly secured in the vehicle.
When securing an add-on child restraint, refer to
the instructions that come with the restraint
which may be on the restraint itself or in a booklet,
or both, and to this manual. The child restraint
instructions are important, so if they are not
available, obtain a replacement copy from the
manufacturer.
Keep in mind that an unsecured child restraint can
move around in a collision or sudden stop and
injure people in the vehicle. Be sure to properly
secure any child restraint in your vehicle — even
when no child is in it.

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 right
front passenger’s frontal airbag if the
system detects a rear-facing child restraint,
CAUTION: (Continued)
CAUTION: (Continued)
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. We recommend
that rear-facing child restraints be secured
in the rear seat, even if the airbag is 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.
If you need to secure a forward-facing child
restraint in the right front seat position, move the
seat as far back as it will go before securing
the forward-facing child restraint. SeeManual
Seats on page 8orPower Seats on page 9.

If your child restraint has the LATCH system, see
Lower Anchors and Tethers for Children (LATCH)
on page 56.
There is no top tether anchor at the right front
seating position. Do not secure a child seat in this
position if a national or local law requires that
the top tether be anchored or if the instructions
that come with the child restraint say that the top
tether must be anchored. SeeLower Anchors
and Tethers for Children (LATCH) on page 56
if the child restraint has a top tether.
You will be using the lap-shoulder belt to secure
the child restraint in this position. Be sure to follow
the instructions that came with the child restraint.
Secure the child in the child restraint when and
as the instructions say.
1. Your vehicle has a right front passenger’s
frontal airbag. SeePassenger Sensing
System on page 82. We recommend that
rear-facing child restraints be secured in
a rear seat, even if the airbag is off.If your child restraint is forward-facing, move
the seat as far back as it will go before
securing the child restraint in this seat. See
Manual Seats on page 8orPower Seats
on page 9.
When the passenger sensing system has
turned off the right front passenger’s frontal
airbag, the off indicator in the passenger airbag
status indicator should light and stay lit
when you turn the ignition to RUN or START.
SeePassenger Airbag Status Indicator
on page 202.
2. Put the child restraint on the seat.
3. Pick up the latch plate, and run the lap and
shoulder portions of the vehicle’s safety belt
through or around the restraint. The child
restraint instructions will show you how.

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 526.
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,
instrument panel, the inside review mirror,
ceiling headliner, ceiling and pillar garnish trim,
roof-mounted airbag modules, 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 526.

Parking Brake
To set the parking brake, hold the regular brake
pedal down with your foot and pull up on the
parking brake lever located between the seats.
If the ignition is on, the brake system warning light
on the instrument panel cluster will come on.
SeeBrake System Warning Light on page 206.To release the parking brake, hold the regular
brake pedal down. Pull the parking brake lever up
until you can press in the button at the end of
the lever. Hold the button in as you move
the parking brake lever all the way down.
Notice:Driving with the parking brake on can
overheat the brake system and cause
premature wear or damage to brake system
parts. Verify that the parking brake is fully
released and the brake warning light is
off before driving.
If you are towing a trailer and you must park on a
hill, seeTowing a Trailer on page 362.

Electric Power Management
This vehicle has Electric Power
Management (EPM), an advanced control
system. It estimates the battery’s temperature
and state of charge and then adjusts the voltage
for best performance and extended life of
the battery.
When the battery’s state of charge is low, the
voltage is raised slightly to quickly put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage, you may
see the voltage move up or down. This is normal.
If there is a problem, an alert will be displayed.
The battery can be discharged at idle if the
electrical loads are very high. This is true for all
vehicles. This is because the generator (alternator)
may not be spinning fast enough at idle to
produce all the power that is needed for very high
electrical loads.A high electrical load occurs when several of the
following loads are on: headlamps, high beams,
fog lamps, rear window defogger, climate
control fan at high speed, heated seats, engine
cooling fans, trailer loads, and loads plugged into
accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s
output and the vehicle’s electrical needs. It
can increase engine idle speed to generate more
power, whenever needed. It can temporarily
reduce the power demands of some accessories.
Normally, these actions occur in steps or levels,
without being noticeable. In rare cases at the
highest levels of corrective action, this action may
be noticeable to the driver. If so, a Driver
Information Center (DIC) message might be
displayed, such as Battery Saver Active or Battery
Voltage Low. If this message is displayed, it is
recommended that the driver reduce the electrical
loads as much as possible. SeeDIC Warnings
and Messages on page 222.

Rear Window Defogger
If your vehicle has the rear window defogger a
warming grid is used to remove fog from the
rear window.
<(Rear):Press this button to turn the rear
window defogger on or off.
An indicator light in the button will come on
to let you know that the rear window defogger
is activated.
The rear window defogger will turn off
approximately 10 minutes after the button is
pressed. If you need additional warming time,
press the button again.
If your vehicle has heated mirrors, they will come
on when this button is pressed.
Notice:Do not use a razor blade or sharp
object to clear the inside rear window. Do not
adhere anything to the defogger grid lines
in the rear glass. These actions may damage
the rear defogger. Repairs would not be
covered by your warranty.
Outlet Adjustment
Use the air outlets located in the center and on the
side of the instrument panel to direct the airow.
Operation Tips

Keep the hood and front air inlets free of ice,
snow, or any other obstruction, such as
leaves. The heater and defroster will work
better, reducing the chance of fogging
the inside of your windows.
When you enter a vehicle in cold weather, set
the fan speed to maximum airow for a few
moments before driving. This helps clear
the intake ducts of snow and moisture, and
reduces the chance of fogging the inside
of your windows.
Keep the air path under the front seats clear
of objects. This helps air to circulate
throughout your vehicle.
Adding outside equipment to the front of the
vehicle, such as hood-air deectors, may
affect the performance of the heating and air
conditioning system. Check with your
dealer before adding equipment to the outside
of your vehicle.
