Front Seat Belt Pretensioner And Load Limiting Systems - Mazda 2012 3 Owner's Manual

Essential Safety Equipment
Seat Belt Systems
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. The front seat belt
retractors remove slack quickly as the air
bags are expanding. Any time the air bags
and front seat belt pretensioners have
deployed they must be replaced.
(With Driver and Front Passenger
Occupant Classification System)
During a side collision, the side air bag,
curtain air bag, and pretensioner system
operate simultaneously on the side in
which the collision occurs.
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 2-57).

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
deployed, the load limiting function must
be checked by an Authorized Mazda
Dealer after any collision.
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 2-18).
