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.
In moderate or severe frontal or near-
frontal collision or roll-over accidents, the
front air bag and pretensioner systems
deploy simultaneously. The front seat belt
retractors remove slack quickly as the air
bags are expanding. The seat belt
pretensioner system cannot provide
adequate protection in an accident if the
seat belt is not fastened properly. The load
limiting system releases belt webbing in a
controlled manner to reduce belt force on
the occupant's chest.
In addition, the pretensioner system for
the front passenger is designed to only
deploy in accordance with the total seated
weight on the front passenger seat. For
details, refer to the driver and front
passenger occupant classification system
(page 2-58).
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 2-17).
WARNING
Do not use seat belts with expended
pretensioners:
One or both front air bags may deploy,
and the corresponding pretensioner(s)
will also deploy at the same time. Use
of front seat belts with the
pretensioner system expended is
dangerous. Like the air bags, the seat
belt pretensioners will only function
once. After they are expended, they
will not function again and must be
replaced immediately. If the seat belt
pretensioners are not replaced, the
risk of injury in a collision will
increase. Always have an Authorized
Mazda Dealer inspect the seat belt
pretensioners and air bags after any
collision. Expended seat belt
pretensioners and air bags must be
replaced after any collision which
caused them to deploy. Additionally,
the load limiter will only limit loads on
the chest once in a collision and this is
another reason to have the front seat
belts inspected.
Do not modify the components or
wiring, or use electronic testing
devices on the pretensioner system:
Modifying the components or wiring
of the pretensioner system, including
the use of electronic testing devices is
dangerous. You could accidentally
activate it or make it inoperable which
would prevent it from activating in an
accident. The occupants or repairers
could be seriously injured.
