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 classi

fi

cation 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

2-67).

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 Air Bag/Front Seat Belt

Pretensioner System Warning

Indication/Warning Light on page

7-32.

(With Front Passenger Occupant

Classi

fi

cation 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 2-71).

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 su

ffi

cient

occupant movement.

Even if the pretensioners have not

fi

red, 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).
