SEATS
– 78 – Y53-6008A
Medium Duty (R05/09)
• If any seat belt is not working properly, see an Autho-
rized Service Center for repair or replacement.
WARNING! Before driving or riding in a vehi-
cle, ensure that there is adequate head clear-
ance at maximum upward travel of seat.
Shorten the tether belt as necessary to pro-
vide adequate head clearance. Serious injury
may occur if head clearance is not adequate.
Tether Belts
Tether belts are installed on suspension seats. They help
secure the seat to the floor to restrain it in case of a sud-
den stop or an accident.
Fixed Tethers
If your Medium Duty has been equipped with fixed length
tethers, no manual adjustment is required. The same
inspection and replacement guidelines should be used as
stated on page 197.
WARNING! Do not remove, modify, or replace
the tether belt system with a different tether
system. A failed or missing tether belt could
allow the seat base to fully extend in the event
of an accident leading to greater injuries or
death.
WARNING! Failure to adjust tether belts prop-
erly can cause excessive movement of the
seat in an accident. This could lead to greater
injuries to you. Tether belts should be
adjusted so that they are taut when the seat is
in its most upward and forward position.
Tether Adjustment
• Make sure that the tether belt is attached to the cab
floor and seat frame. It should be routed through the
buckle on each side.
• Often the attachments are made using a split-type
hook. Make sure both halves of the hook are around
the anchor bracket.
• To lengthen the tether, turn the buckle to a right angle
to the webbing. Then pull the buckle. To shorten the
tether, pull on the strap.
