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
2-82).
The front 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 Taking Action on page 7-37.
Refer to Air Bag/Front Seat Belt
Pretensioner System Warning Beep on
page 7-47.

(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 when the front passenger occupant

classification sensor detects a passenger
sitting on the front passenger's seat.
For details, refer to the front passenger
occupant classification sensor (page
2-85).
 

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 2-38).
