Regional Haul Model Operator's Manual - Peterbilt Motors Company

TETHER BELTS
• If any seat belt is not working properly, see an Authorized
Service Center for repair or replacement.
Tether Belts
WARNING! Before driving or riding in a vehicle,
ensure that there is adequate head clearance
at maximum upward travel of seat.
Shorten the tether belt as necessary to provide
adequate head clearance. Death or serious
injury may occur if head clearance is not
adequate.
Tether belts are installed on suspension seats. They help
secure the seat to the floor to restrain it in case of a sudden
stop or an accident.
Fixed Tethers
If your Regional Haul vehicle 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 229.
SEATS
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 properly
can cause excessive movement of the
seat in an accident. This could lead to death
or 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.
