Seat Belt Pretensioner and
Load Limiting Systems
For optimum protection, the driver and
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 air bag and
pretensioner systems deploy
simultaneously. The seat belt retractors
remove slack quickly as the air bags are
expanding.
In addition, the pretensioner system for
the passenger, like the passenger air bag,
is designed to only deploy in accordance
with the total seated weight on the
passenger seat (page 2-38) or when the
passenger air bag deactivation switch
turned to the ON position (page 2-32).
Any time the air bags and seat belt
pretensioners have fired they must be
replaced.
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
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 2-9).
