2007 GMC SIERRA CLASSIC ECU

For crew cab models, there are covered top tether
anchors for each seating position located on the
back panel of your vehicle, behind the rear
seat. Remove the trim covers to access the
anchors.Do not secure a child restraint in the front
passenger’s position if your vehicle has rear seats,
if a national or local law requires that the top
tether be attached, or if the instructions that come
with the child restraint say that the top tether
must be attached. There is no place to attach the
top tether in this position.
Accident statistics show that children are safer if
they are restrained in the rear rather than the front
seat. SeeWhere to Put the Restraint on page 55
for additional information.

Securing a Child Restraint Designed for
the LATCH System
{CAUTION:
If a LATCH-type child restraint is not
attached to anchors, the restraint will not
be able to protect the child correctly. In a
crash, the child could be seriously injured
or killed. Make sure that a LATCH-type
child restraint is properly installed using
the anchors, or use the vehicle’s safety
belts to secure the restraint, following the
instructions that came with that restraint,
and also the instructions in this manual.
{CAUTION:
Each top tether anchor, except the center
top tether anchor in an extended cab
model, and lower anchors in the vehicle
are designed to hold only one child
restraint. Attaching more than one child
restraint to a single anchor could cause
the anchor or attachment to come loose
or even break during a crash. A child or
others could be injured if this happens. To
help prevent injury to people and damage
to your vehicle, attach only one child
restraint per anchor.
64

{CAUTION:
Children can be seriously injured or
strangled if a shoulder belt is wrapped
around their neck and the safety belt
continues to tighten. Secure any unused
safety belts behind the child restraint so
children cannot reach them. Pull the
shoulder belt all the way out of the
retractor to set the lock, if your vehicle
has one, after the child restraint has been
installed. Be sure to follow the
instructions of the child restraint
manufacturer.
Notice:Contact between the child restraint or
the LATCH attachment parts and the vehicle’s
safety belt assembly may cause damage to
these parts. Make sure when securing unused
safety belts behind the child restraint that
there is no contact between the child restraint
or the LATCH attachment parts and the
vehicle’s safety belt assembly.Folding an empty rear seat with the safety
belts secured may cause damage to the safety
belt or the seat. When removing the child
restraint, always remember to return the safety
belts to their normal, stowed position before
folding the rear seat.

Rear Seat Position
Extended Cab and Crew Cab
There is limited space in the rear seating of an
extended cab model. If you want to secure a child
restraint in a rear seating position, be sure to
study the instructions that came with your child
restraint to see if there is enough room to secure
your seat properly.
If your child restraint has the LATCH system, see
Lower Anchors and Tethers for Children
(LATCH) on page 58.
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 child 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, 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.6. If your child restraint manufacturer

Securing a Child Restraint in the
Center Front Seat Position
{CAUTION:
A child in a child restraint in the center
front seat can be badly injured or killed by
the right front passenger’s airbag if it
inates. Never secure a child restraint in
the center front seat. It is always better to
secure a child restraint in the rear seat.
Do not use child restraints in this position.
Securing a Child Restraint in the
Right Front Seat Position
(Crew Cab) (With Passenger
Sensing System)
Your vehicle has a right front passenger airbag.
Neverput a rear-facing child restraint in the
right front passenger’s seat. Here is why:
{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. Always secure a
rear-facing child restraint in a rear seat.
