Peterbilt Medium Duty Trucks Operator's Manual after 1-07

Seats
• The belts must be kept clean or the retractors may not
work properly.
• Never bleach or dye seat belts: chemicals can weaken
them. Do, however, keep them clean by following the
care label on the belts. Let them dry completely before
allowing them to retract.
• Make sure the belt of the unoccupied passenger seat is
fully wound up on its retractor, so that the belt tongue is
in its stowed position. This reduces the possibility of the
tongue becoming a striking object in case of a sudden
stop.
• Do not modify or disassemble the seat belts in your vehicle.
They will not be available to keep you and your passengers
safe.
• If any seat belt is not working properly, see an Authorized
Service Center for repair or replacement.
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. Serious injury may occur if head
clearance is not adequate.
Tether Belts
Operating Instructions
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 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 properly
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.
