Unfastening center lap safety belts
Safety Belt Extension Assembly
For some people, the safety belt may be too
short even when it is fully extended. You can
add about eight inches (20 cm) to the belt length
with a safety belt extension assembly (part
number 611C22). Safety belt extensions are
available at no cost from your dealer.
Failure to follow these instructions will
affect the performance of the safety belts
and increase the risk of personal injury.
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. Do not use extension
to change the fit of the shoulder belt across the
torso.
