2008 Chevrolet Tahoe Owner's Manual - Page 70

For vehicles with a three passenger third row seat, there is one top tether anchor located at the bottom rear of the seat cushion that can be used for either the third row center or driver side seating position. Never install two top tethers using the same top tether anchor. Do not secure a child restraint in a position without a top tether anchor 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. Accident statistics show that children are safer if they are restrained in the rear rather than the front seat. See Where to Put the Restraint on page 1-60 for additional information. Third Row Seat - Two or Three Passenger For vehicles with a two passenger third row seat, there is one top tether anchor located at the bottom rear of the seat cushion that can be used for the rear driver side seating position in the third row. Never install two top tethers using the same top tether anchor. 1-66
