Safety belt extension assembly
If the safety belt is too short when fully extended, there is an 8 inch
(20 cm) safety belt extension assembly that can be added (part number
611C22). This assembly can be obtained from an authorized dealer.
Use only extensions manufactured by the same supplier as the safety
belt. Manufacturer identification is located at the end of the webbing on
the label. Also, use the safety belt extension only if the safety belt is too
short for you when fully extended.
WARNING: Do not use extensions to change the fit of the
shoulder belt across the torso.
