{CAUTION:
You can be seriously hurt if your shoulder belt
is too loose. In a crash, you would move
forward too much, which could increase injury.
The shoulder belt should t against your body.
To unlatch the belt, just push the button on the buckle.
Rear Safety Belt Comfort Guides for
Children and Small Adults
Rear shoulder belt comfort guides provide added safety
belt comfort for older children who have outgrown
booster seats and for small adults. When attached to a
shoulder belt, the comfort guide better positions the
belt away from the neck and head.
There is one guide for each of the rear outside
passenger positions. Here is how to attach the comfort
guide to the shoulder belt.
1. Find the comfort guide located on a storage clip
between the interior body and the seatback or in
a pocket sewn into the side of the seatback.
Slide the guide off of its storage clip or out of
the pocket.

Safety Belt Pretensioners
Your vehicle has safety belt pretensioners. Although
you cannot see them, they are located on the retractor
part of the safety belts for the driver and right front
passenger. They help the safety belts reduce a person’s
forward movement in a moderate to severe frontal,
near frontal or side crash or a rollover.
Pretensioners work only once. If they activate in a
crash, you will need to get new ones, and probably other
new parts for your safety belt system. SeeReplacing
Restraint System Parts After a Crash on page 1-64.
Safety Belt Extender
If the vehicle’s safety belt will fasten around you, you
should use it.
But if a safety belt is not long enough, your dealer will
order you an extender. It is free. When you go in to
order it, take the heaviest coat you will wear, so
the extender will be long enough for you. To help avoid
personal injury, do not let someone else use it, and
use it only for the seat it is made to t. The extender has
been designed for adults. Never use it for securing
child seats. To wear it, just attach it to the regular safety
belt. For more information, see the instruction sheet
that comes with the extender.
Child Restraints
Older Children
Older children who have outgrown booster seats should
wear the vehicle’s safety belts.

A forward-facing child seat (C-E) provides restraint for
the child’s body with the harness and also sometimes
with surfaces such as T-shaped or shelf-like shields.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.

Securing a Child Restraint in the
Center Seat Position
Many child restraints are too wide to be correctly
secured in the center rear seat, although some of them
will t there. If the center seat position is too narrow
for your child restraint, secure it in a rear outside seat
position.
If you secure a child restraint in the center seat position,
follow the instructions inSecuring a Child Restraint in
a Rear Outside Seat Position on page 1-41.
Securing a Child Restraint in the
Right Front Seat Position
Your vehicle has a right front passenger airbag. A rear
seat is a safer place to secure a forward-facing child
restraint. SeeWhere to Put the Restraint on page 1-34.
In addition, your vehicle has a passenger sensing
system. The passenger sensing system is designed to
turn off the right front passenger’s frontal airbag
when an infant in a rear-facing infant seat or a small
child in a forward-facing child restraint or booster seat is
detected. SeePassenger Sensing System on page 1-58
andPassenger Airbag Status Indicator on page 3-37
for more information on this including important
safety information.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 passenger’s frontal
airbag if the system detects a rear-facing child
restraint, 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. General Motors recommends 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 position, move the seat as far
back as it will go before securing the forward-facing
child restraint. SeePower Seats on page 1-2.
1-43

If your child restraint is equipped with the LATCH
system, seeLower Anchorages and Top Tethers for
Children (LATCH System) on page 1-38.
There is no top strap 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 strap be
anchored or if the instructions that come with the child
restraint say that the top strap must be anchored. See
Top Strap on page 1-35if your child restraint has one.
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 1-58. General Motors recommends 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. SeePower Seats on page 1-2.
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 3-37.
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, 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.
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 (located under the driver’s seat), or
the inside rearview mirror 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 7-2.

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 3-40.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.

Outlet Adjustment
Use the air outlets located in the center and on the side
of your 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 far better, reducing
the chance of fogging the inside of your windows.
When you enter a vehicle in cold weather, turn the
fan knob all the way to the right 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 window.
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 your
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.
Rear Climate Control System
Envoy
Your vehicle has one of the following rear climate
control systems. With any of these systems, the rear
climate controls will be disabled when the front climate
control system is in defrost. This occurs to provide
maximum airow to clear the windshield.
The rear mode and temperature positions now mimic
the front control system mode and passenger
side temperature.

{CAUTION:
Do not load your vehicle any heavier than the
Gross Vehicle Weight Rating (GVWR), or either
the maximum front or rear Gross Axle Weight
Rating (GAWR). If you do, parts on your
vehicle can break, and it can change the way
your vehicle handles. These could cause you
to lose control and crash. Also, overloading
can shorten the life of your vehicle.
Using heavier suspension components to get added
durability might not change your vehicle’s weight ratings.
Ask your dealer to help you load your vehicle
the right way.
Notice:Overloading your vehicle may cause
damage. Repairs would not be covered by your
warranty. Do not overload your vehicle.
If you put things inside your vehicle — like suitcases,
tools, packages, or anything else — they will go as fast
as the vehicle goes. If you have to stop or turn
quickly, or if there’s a crash, they will keep going.
{CAUTION:
Things you put inside your vehicle can strike
and injure people in a sudden stop or turn, or
in a crash.
Put things in the cargo area of your
vehicle. Try to spread the weight evenly.
Never stack heavier things, like suitcases,
inside the vehicle so that some of them
are above the tops of the seats.
Do not leave an unsecured child restraint
in your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.
Do not leave a seat folded down unless
you need to.
