Info - Availability of Rear Seat Shoulder Belt Comfort Guides

This bulletin is being revised to change interior color information for the TrailBlazer EXT and Envoy XL. Please discard Corporate Bulletin Number 02-09-40-005 (Section 09 -- Restraints).

Some early 2003 production vehicles were manufactured without rear seat shoulder belt comfort guides. This comfort guide is a plastic guide attached to a short elastic tether that positions the shoulder belt away from the neck of short occupants, whether children or adults. A rear seat shoulder belt comfort guide may help improve the comfort of the shoulder portion of the safety belt for occupants sitting in the rear outboard seating positions.

While these vehicles comply with all Federal Motor Vehicle Safety Standards, some customers may request to have these comfort guides installed on their vehicle. Comfort guides are currently available from GMSPO (see parts table below).

Upon customer request, dealers are authorized to install these rear seat shoulder belt comfort guides -- at no cost to the customers.
