Protecting Children Important Safety Information Keep the third seat in the floor while using a tether-style child seat in the second seat. If you attempt to return the third seat to the upright position, you may damage the vehicle or tether, even though the damage may not be obvious. If this happens, the child seat may not be properly restrained in a crash. Third Seat Installation: There are two attachment points on the tailgate sill. Select the attachment point you want use, and remove the plug with a small flattipped screwdriver or a fingernail file. Install the tether hardware that came with the child seat. Tighten the bolt to: 16 lbf.ft (22 N . m, 2.2 kgf.m) If you are not sure how to install the hardware, have it installed by your authorized Honda dealer. The anchor plate and mounting hardware for a top tether are supplied with the vehicle. When installing, make sure the toothed washer is on the bottom of the bolt. Driver and Passenger Safety
