ECU CHEVROLET AVALANCHE 2004 1.G User Guide

Securing a Child Restraint Designed
for the LATCH System
1. Find the LATCH anchorages for the seating
position you want to use, where the bottom of the
seatback meets the back of the seat cushion.
SeeLower Anchorages and Top Tethers for
Children (LATCH System) on page 1-42.
2. Put the child restraint on the seat.
3. Attach and tighten the LATCH attachments on the
child restraint to the LATCH anchorages in the
vehicle. The child restraint instructions will
show you how.
4. If the child restraint is forward-facing, attach and
tighten the top tether to the top tether anchorage.
The child restraint instructions will show you
how. Also seeTop Strap on page 1-40.
5. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, simply unhook the top
tether from the top tether anchorage and then
disconnect the LATCH attachments from the LATCH
anchorages.
Securing a Child Restraint in a
Rear Seat Position
If your child restraint is equipped with the LATCH
system seeLower Anchorages and Top Tethers for
Children (LATCH System) on page 1-42. SeeTop Strap
on page 1-40if the child restraint has one.
If your child restraint does not have the LATCH system,
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. Put the restraint on the seat.
2. 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.

5. To tighten the belt, feed the shoulder belt back into
the retractor while you push down on the child
restraint. If you are using a forward-facing child
restraint, you may nd it helpful to use your knee to
push down on the child restraint as you tighten
the belt.
6. Push and pull the child restraint in different
directions to be sure it is secure.To remove the child restraint, just unbuckle the vehicle’s
safety belt and let it go back all the way. The safety
belt will move freely again and be ready to work for an
adult or larger child passenger.
Securing a Child Restraint in the
Center Front Seat Position
Don’t use child restraints in this position. The restraints
won’t work properly.

Securing a Child Restraint in the
Right Front Seat Position
Your vehicle has a right front passenger air bag. A rear
seat is a safer place to secure a forward-facing child
restraint. SeeWhere to Put the Restraint on page 1-38.
In addition, your vehicle may have the passenger
sensing system. The passenger sensing system is
designed to turn off the right front passenger’s frontal air
bag 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 1-62andPassenger Air Bag Status Indicator
on page 3-38for 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 air bag deploys.
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s air bag inates. This is because
the back of the rear-facing child restraint
would be very close to the inating air bag.
Even though the passenger sensing system is
designed to turn off the passenger’s frontal air
bag if the system detects a rear-facing child
restraint, no system is fail-safe, and no one
can guarantee that an air bag 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 air bag
is off.
1-47

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 1-2orManual
Passenger Seat on page 1-2.
If your child restraint is equipped with the LATCH
system, seeLower Anchorages and Top Tethers for
Children (LATCH System) on page 1-42.
There is no top strap anchor in the right front
passenger’s 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. SeeTop Strap on page 1-40if your child
restraint has one.You will be using the lap-shoulder belt to secure the
child restraint in this position. SeeTop Strap on
page 1-40if your child restraint has one. 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 air
bag. SeePassenger Sensing System on page 1-62.
General Motors recommends that rear-facing
child restraints be secured in a rear seat, even if
the air bag 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 1-2orManual
Passenger Seat on page 1-2.
When the passenger sensing system has turned off
the right front passenger’s frontal air bag, the off
indicator in the passenger air bag status indicator
should light and stay lit when you turn the ignition to
RUN or START. SeePassenger Air Bag Status
Indicator on page 3-38.
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.
1-48

6. To tighten the belt, push down on the child restraint,
pull the shoulder portion of the belt to tighten the
lap portion of the belt and feed the shoulder belt
back into the retractor. If you are using a
forward-facing child restraint, you may nd it helpful
to use your knee to push down on the child
restraint as you tighten the belt. You should not be
able to pull more of the belt from the retractor
once the lock has been set.7. Push and pull the child restraint in different
directions to be sure it is secure.
8. If your vehicle has the passenger sensing system
and the air bag is off, the off indicator will be lit and
stay lit in the inside rearview mirror when the key
is turned to RUN or START.
If a child restraint has been installed and the on
indicator is lit, turn the vehicle off. Remove the child
restraint from the vehicle and reinstall the child restraint.
If after reinstalling the child restraint and restarting
the vehicle, the on indicator is still lit, check to make
sure that the vehicle’s seatback is not pressing the child
restraint into the seat cushion. If this happens, slightly
recline the vehicle’s seatback and adjust the seat
cushion if possible. Also make sure the child restraint is
not trapped under the vehicle head restraint. If this
happens, adjust the head restraint.
If the on indicator is still lit, secure the child in the child
restraint in a rear seat position in the vehicle and check
with your dealer.
To remove the child restraint, just unbuckle the vehicle’s
safety belt and let it go back all the way. The safety
belt will move freely again and be ready to work for an
adult or larger child passenger.

{CAUTION:
Both frontal and side impact air bags inate
with great force, faster than the blink of an
eye. If you are too close to an inating air bag,
as you would be if you were leaning forward, it
could seriously injure you. Safety belts help
keep you in position for air bag ination before
and during a crash. Always wear your safety
belt, even with frontal air bags. The driver
should sit as far back as possible while still
maintaining control of the vehicle. Front
occupants should not lean on or sleep against
the door.
{CAUTION:
Anyone who is up against, or very close to,
any air bag when it inates can be seriously
injured or killed. Air bags plus lap-shoulder
belts offer the best protection for adults, but
not for young children and infants. Neither the
vehicle’s safety belt system nor its air bag
system is designed for them. Young children
and infants need the protection that a child
restraint system can provide. Always secure
children properly in your vehicle. To read how,
see the part of this manual called “Older
Children” or “Infants and Young Children.”

Passenger Sensing System
If your rearview mirror has one of the indicators pictured
in the following illustrations, your vehicle has a
passenger sensing system. The indicator will be visible
when you turn your ignition key to START or RUN.
The words ON and OFF or the symbol for on and off,
will be visible on the rearview mirror during the system
check. When the system check is complete, either
the word ON or the word OFF, or the symbol for on or
the symbol for off will be visible. SeePassenger Air
Bag Status Indicator on page 3-38. If your rearview
mirror does not have either of the indicators pictured,
then your vehicle does not have the passenger
sensing system.The passenger sensing system will turn off the right
front passenger’s frontal air bag under certain
conditions. The driver’s air bag and the side air bags
are not part of the passenger sensing system.
The passenger sensing system works with sensors that
are part of the right front passenger’s seat and safety
belt. The sensors are designed to detect the presence
of a properly-seated occupant and determine if the
passenger’s frontal air bag should be enabled
(may inate) or not.
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat.
General Motors recommends that child restraints
be secured in a rear seat, including an infant riding in a
rear-facing infant seat, a child riding in a forward-facing
child seat and an older child riding in a booster seat.
Your vehicle has a rear seat that will accommodate
a rear-facing child restraint. 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 air bag deploys. Passenger Air Bag Status Indicator – United States

{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s air bag inates. This is because
the back of the rear-facing child restraint
would be very close to the inating air bag.
Even though the passenger sensing system is
designed to turn off the passenger’s frontal air
bag if the system detects a rear-facing child
restraint, no system is fail-safe, and no one
can guarantee that an air bag 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 air bag
is off.The passenger sensing system is designed to turn off
the right front passenger’s frontal air bag if:
the right front passenger seat is unoccupied
the system determines that an infant is present in a
rear-facing infant seat
the system determines that a small child is present
in a forward-facing child restraint
the system determines that a small child is present
in a booster seat
a right front passenger takes his/her weight off of
the seat for a period of time
the right front passenger seat is occupied by a
smaller person, such as a child who has outgrown
child restraints
or if there is a critical problem with the air bag
system or the passenger sensing system.
When the passenger sensing system has turned off the
passenger’s frontal air bag, the off indicator will light
and stay lit to remind you that the air bag is off.
If a child restraint has been installed and the on indicator
is lit, turn the vehicle off. Remove the child restraint from
the vehicle and reinstall the child restraint following the
child restraint manufacturer’s directions and refer to
Securing a Child Restraint in the Right Front Seat
Position on page 1-47.
1-63

If after reinstalling the child restraint and restarting the
vehicle, the on indicator is still lit, check to make
sure that the vehicle’s seatback is not pressing the child
restraint into the seat cushion. If this happens, slightly
recline the vehicle’s seatback and adjust the seat
cushion if possible. Also make sure the child restraint is
not trapped under the vehicle head restraint. If this
happens, adjust the head restraint.
If the on indicator is still lit, secure the child in the child
restraint in a rear seat position in the vehicle and
check with your dealer.
The passenger sensing system is designed to enable
(may inate) the right front passenger’s frontal air
bag anytime the system senses that a person of adult
size is sitting properly in the right front passenger’s seat.
When the passenger sensing system has allowed the
air bag to be enabled, the on indicator will light and stay
lit to remind you that the air bag is active.
For some children who have outgrown child restraints
and for very small adults, the passenger sensing system
may or may not turn off the right front passenger’s
frontal air bag, depending upon the person’s seating
posture and body build. Everyone in your vehicle
who has outgrown child restraints should wear a safety
belt properly — whether or not there is an air bag
for that person.If a person of adult-size is sitting in the right front
passenger’s seat, but the off indicator is lit, it could be
because that person is not sitting properly in the seat. If
this happens, turn the vehicle off and ask the person to
place the seatback in the fully upright position, then sit
upright in the seat, centered on the seat cushion, with the
person’s legs comfortably extended. Restart the vehicle
and have the person remain in this position for about two
minutes. This will allow the system to detect that person
and then enable the passenger’s air bag.

Servicing Your Air Bag-Equipped
Vehicle
Air bags affect how your vehicle should be serviced.
There air bag system parts in several places around
your vehicle. You don’t 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 air bag system. To purchase a
service manual, seeService Publications Ordering
Information on page 7-13.
{CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected,
an air bag can still inate during improper
service. You can be injured if you are close
to an air bag when it inates. Avoid yellow
connectors. They are probably part of the air
bag system. Be sure to follow proper service
procedures, and make sure the person
performing work for you is qualied to do so.
Air bag systems do not need regular maintenance.
Adding Equipment to Your
Air Bag-Equipped Vehicle
Q:Is there anything I might add to the front or
sides of the vehicle that could keep the air
bags 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 air bag system
from working properly. Also, the air bag system
may not work properly if you relocate any of the air
bag 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.
