DEALER INSTALLED ANCHOR CHILD SEAT WITH TOP STRAP

Models: 110 & 125 Inch Wheelbase "G" Vans, Caballero, S-T Pickups, Extended Cabs & Jimmy's & C-K Trucks

Note: All hardware discussed in this bulletin should be supplied or available from the child seat manufacturer. Be sure the child seat position does not conflict with any additional requirements provided by its manufacturer, or with any recommendations in the Child Restraint section of the Owner's Manual.

The child seat may be used only in a forward facing seating location. However, installation is not recommended in the front passenger seat of "G" Vans. The second seat offset to allow passenger entry does not position a second seat lap belt within the recommended zone for attachment to the top strap hook. Moreover, a floor anchorage is impractical since the top strap length is insufficient to directly connect the restraint to the floor with high back bucket seats.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
