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:

When a collision is detected, the
pretensioners deploy simultaneously
with the air bags.
For vehicles with the front passenger
occupant classification 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
2-63).
 
The seat belt retractors remove slack
quickly as the air bags are expanding.
Any time the air bags and seat belt
pretensioners have fired they must be
replaced.
A system malfunction or operation
conditions are indicated by a warning.
Refer to Air Bag/Front Seat Belt
Pretensioner System Warning
Indication/Warning Light on page
7-27.

(With Front Passenger Occupant
Classification System)

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 2-67).
 

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 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 Belt"
(page 2-24).
