2010 GMC Canyon Extended Cab Owner's Manual - Page 79

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 2-44 for additional information. Regular and Extended Cab without Rear Seats 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. 2-51
