Seat Belt Pretensioner And Load Limiting Systems - Mazda mx5 Owner's Manual

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
2-44 ).
The seat belt retractors remove slack
quickly as the air bags are expanding.
Any time the air bags and seat belt
pretensioners have fi red they must be
replaced.
A system malfunction or operation
conditions are indicated by a warning.
Refer to Warning/Indicator Lights on page
4-32 .
Refer to Air Bag/Seat Belt Pretensioner
System Warning Beep on page 7-48 .
(With Passenger Occupant
Classifi cation System)
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
classifi cation sensor detects a passenger
sitting on the passenger's seat.
For details, refer to the passenger occupant
classifi cation sensor (page 2-47 ).

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
suffi cient occupant movement.
Even if the pretensioners have not fi red,
the load limiting function must be checked
by an expert repairer, we recommend an
Authorised Mazda Repairer.
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 2-12 ).
Have your seat belts changed
immediately if the pretensioner or load
limiter has been expended:
Always have an expert repairer, we
recommend an Authorised Mazda
Repairer 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. If the seat
belt pretensioners and load limiters
are not replaced, the risk of injury in a
collision will increase.
