Safety Restraint System — Inspection
The seat belt system, including webbing, buckles, latches,
and mounting hardware, endures heavy use in medium-duty
vehicles—much more than seat belt systems in passenger
cars. All users should be aware of the factors contributing to
this heavy use and reduced belt life.
WARNING! Failure to properly inspect and maintain
restraint systems can lead to serious injury
or loss of life. Without periodic inspection and
maintenance to detect unsafe conditions, seat
restraint components can wear out or not protect
you in an accident.
Factors contributing to reduced seat belt life:

in excess of 500,000 total miles (800,000 km) during the
vehicle lifetime. This is much greater than a typical passenger
car, which frequently will not exceed 125,000

and seat design. The constant movement of the belt
