Essential Safety Equipment
Seat Belt Systems
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:
When a collision is detected, the
pretensioners deploy simultaneously with
the air bags.
For deployment details, refer to the SRS
Air Bag Deployment Criteria (page
2-46).
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 Taking Action on page 7-40.
Refer to Air Bag/Seat Belt Pretensioner
System Warning Beep on page 7-48.
In addition, the pretensioner system for the
passenger, like the front and side
passenger air bag, is designed to only
deploy when the passenger occupant
classification sensor detects a passenger
sitting on the passenger's seat.
For details, refer to the passenger occupant
classification sensor (page 2-49).

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 2-16).
Have your seat belts changed immediately
if the pretensioner or load limiter has been
expended:
Always have an Authorized Mazda Dealer
immediately inspect the seat belt
pretensioners and air bags after any collision.
Like the air bags, the seat belt pretensioners
and load limiters will only function once and
must be replaced after any collision that
caused them to deploy. A seat belt with an
expended pretensioner or load limiter is still
better than wearing no seat belt at all;
however, if the seat belt pretensioners and
load limiters are not replaced, the risk of
injury in a collision will increase.
