ECU CHEVROLET TAHOE 2003 2.G Owner's Manual

Second Row
The center seat position in the second row has a
lap-shoulder belt which works the same way as the
safety belt in the rear outside seat positions. For
instructions on how to secure a child restraint using a
lap-shoulder belt see
Securing a Child Restraint in
a Rear Outside Seat Position on page 1-64.
Third Row
The center seat position in the third row has a lap belt.
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. Make the belt as long as possible by tilting the latch
plate and pulling it along the belt.
2. Put the restraint on the seat.
3. Run the vehicle's safety belt through or around the
restraint. The child restraint instructions will show
you how.
1-67

4. Buckle the belt. Make sure the release button is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.
5. To tighten the belt, pull its free end while you push
down on the child restraint. If you're 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. It will 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.
1-68

Securing a Child Restraint in the
Right Front Seat PositionYour vehicle has a right front passenger air bag.
Although a rear seat is a safer place, you can secure a
forward-facing child restraint in the right front seat.
Unless your vehicle has the passenger sensing system,
Neverput a rear-facing child restraint in this seat.
Here's why:
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger's air bag in¯ates. This is because
the back of the rear-facing child restraint
would be very close to the in¯ating air bag.
Always secure a rear-facing child restraint in a
rear seat unless the air bag is off.
1-69

If your vehicle has the passenger sensing system and
you need to secure a rear-facing child restraint in
the right front passenger's seat, the passenger's air bag
must be off. See
Passenger Sensing System on
page 1-83andPassenger Air Bag Status Indicator on
page 3-39for more information on this including
important safety information.
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger's air bag in¯ates. This is because
the back of the rear facing child restraint
would be very close to the in¯ating air bag. Be
sure the air bag is off before using a
rear-facing child restraint in the right front seat
position.
CAUTION: (Continued)
CAUTION: (Continued)
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
therefore recommends that rear-facing child
restraints be secured in the rear seat whenever
possible, even if the air bag is off.
If your child restraint is equipped with the LATCH
system, see
Lower Anchorages and Top Tethers for
Children (LATCH System) on page 1-62. SeeTop Strap
on page 1-57if the child restraint has one.
If your child restraint does not have the LATCH system,
you'll 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.
1-70

1. Because your vehicle has a right front passenger
air bag, always move the seat as far back as it will
go before securing a forward-facing child restraint.
See
Power Seats on page 1-4orManual Seats
on page 1-3.
If your vehicle has the passenger sensing system
and you are using a rear-facing child restraint in this
seat, make sure the frontal air bag is off. See
Passenger Sensing System on page 1-83.
When the passenger sensing system has turned off
the right front passenger's frontal air bag, the off
indicator on the inside rearview mirror will light and
stay lit when you turn the ignition to RUN or START.
2. Put the 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.4. Buckle the belt. Make sure the release button is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.
1-71

5. Pull the rest of the shoulder belt all the way out of
the retractor to set the lock.6. To tighten the belt, feed the shoulder belt back into
the retractor while you push down on the 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
out of the retractor once the lock has been set.
7. Push and pull the child restraint in different
directions to be sure it is secure.
1-72

{CAUTION:
Both frontal and side impact air bags in¯ate
with great force, faster than the blink of an eye.
If you're too close to an in¯ating 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 in¯ation 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 in¯ates 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 ªOlder
Childrenº or ªInfants and Young Children.º
1-75

Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat.
General Motors, therefore, 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. Never put a child in rear-facing child
restraint in the right front passenger seat unless your
vehicle has the passenger sensing system and the
passenger air bag status indicator shows off. Never put
a rear-facing child restraint in the right front passenger
seat unless the air bag is off.
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger's air bag in¯ates. This is because
the back of the rear-facing child restraint
would be very close to the in¯ating air bag. Be
sure the air bag is off before using a
rear-facing child restraint in the right front seat
position.

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,
therefore, recommends that rear-facing child
restraints be secured in the rear seat whenever
possible, 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
1-84

·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.
The passenger sensing system is designed to turn off
the passenger's frontal air bag when a rear facing infant
seat, a forward-facing child restraint or a booster seat
is detected. If the 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
restraint following the child restraint manufacturer's
directions and refer to
Securing a Child Restraint in the
Right Front Seat Position on page 1-69of this manual.
If after reinstalling the child restraint and restarting
the vehicle, 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 in¯ate) 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 Ð 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 isn't sitting properly in the seat. If
this happens, turn the vehicle off and ask the person to
place the seatback in the full 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.
