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
2-68).
 
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 7-31.
Refer to Air Bag/Front Seat Belt
Pretensioner System Warning Beep on
page 7-41.

(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 2-72).
 

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 2-26).
