Tether Belts
PART 5: SEAT AND RESTRAINT SYSTEMS
Tether Adjustment
WARNING!
• Failure to adjust tether belts properly can
cause excessive movement of the seat in an
accident. This could lead to greater injuries
for you. Tether belts should be adjusted so
that they are taut when the seat is in its most
upward and forward position.
• Before driving or riding in a vehicle, ensure
that there is adequate head clearance at maximum
upward travel of seat. Serious injury
may occur if head clearance is not adequate.
Shorten the tether belt as necessary to provide
adequate head clearance.

• Make sure the tether belt is attached to the cab deck
and seat frame. It should be routed through the buckle
on each side.
• 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.
