Front Seat Belt 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:
In moderate or severe frontal or near-
frontal accidents, the front air bag and
pretensioner systems deploy
simultaneously when the seat belt is worn.
If the front seat occupant is not wearing a
seat belt, that person's pretensioner will
not fire even if the air bag does. The front
seat belt retractors remove slack quickly
as the air bags are expanding.
In addition, the pretensioner system for
the front passenger, like the front
passenger air bag, is designed to only
deploy in accordance with the total seated
weight on the front passenger seat. Any
time the air bags and seat belt
pretensioners have fired they must be
replaced. For details, refer to the front
passenger seat weight sensors (page 2-49).
Load limiter:
The load limiting system releases belt
webbing in a controlled manner to reduce
belt force on the occupant's chest. While
the most severe load on a seat belt occurs
in frontal collisions, the load limiter has
an automatic mechanical function and can
activate in any accident mode with
sufficient occupant movement.
Even if the pretensioners have not fired,
the load limiting function must be
checked by an Authorized Mazda Dealer.
WARNING
Wear seat belts only as recommended
in this owner's manual:
Incorrect positioning of the driver and
front passenger seat belts is
dangerous. Without proper
positioning, the pretensioner and load
limiting systems cannot provide
adequate protection in an accident
and this could result in serious injury.
For more details about wearing seat
belts, refer to “Fastening the seat
belts” (page 2-13).
