2006 Chevrolet Colorado Owner's Manual - Page 56

Do not secure a child restraint in the right front passenger's position of a vehicle that 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. See Where to Put the Restraint on page 1-44 for additional information. Extended Cab - Rear Seat For regular and extended cab models without rear seats, there is a top tether anchor located behind a removable cover on the back wall behind the right front passenger seat. You may have to pull the seatback forward to access the anchor. 1-50
