Pontiac 2006 G6 Owner's Manual page 53

You cannot secure three child restraints using the
LATCH anchors in the rear seat at the same time, but
you can install two of them. If you want to do this, install
one LATCH child restraint in the passenger-side
position, and install the other one either in the
driver's-side position or in the center position. Refer to
the following illustration to learn which anchors to use.
A. Passenger's Side Rear Seat Lower Anchors
B. Center Rear Seat Lower Anchors
C. Driver's Side Rear Seat Lower Anchors
Sedan
Make sure to attach the child restraint at the proper
anchor location.
This system is designed to make installation of child
restraints easier. When using lower anchors, do not use
the vehicle's safety belts. Instead, use the vehicle's
anchors and child restraint attachments to secure the
restraints. Some restraints also use another vehicle
anchor to secure a top tether.
1. Find the lower anchors, if equipped, for the desired
seating position.
2. If the desired seating position does not have lower
anchors, see Securing a Child Restraint in a Rear
Seat Position on page 1-49 for instructions on
installing the child restraint using the safety belts.
3. Put the child restraint on the seat.
