Pretensioner and Load 
Limiting Systems

    For optimum protection, the driver and 
front passenger seat belts are equipped 
with pretensioner and load limiting 
systems. For both these systems to work 
properly you must wear the seat belt 
properly.

Pretensioners:

  When a collision is detected, the 
pretensioners deploy simultaneously with 
the air bags.
  For vehicles with the front passenger 
occupant classifi cation system, the 
pretensioners deploy simultaneously 
with the air bags when a roll-over is also 
detected.
  For deployment details, refer to the SRS 
Air Bag Deployment Criteria (page 2-53 ).
  The front seat belt retractors remove slack 
quickly as the air bags are expanding. 
Any time the air bags and seat belt 
pretensioners have fi red they must be 
replaced.
  A system malfunction or operation 
conditions are indicated by a warning.

  In addition, the pretensioner system for 
the front passenger, like the front and side 
passenger air bag, is designed to only 
deploy in accordance with the total seated 
weight on the front passenger seat.
  For details, refer to the front passenger 
seat weight sensors (page  2-56 ).
