Front Seat Belt
Pretensioner and Load Limiting Systems
▼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 t he 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
2-68).

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 Air Bag/Front Seat Belt
Pretensioner System Warning Indication/
Warning Light on page 7-32.
Refer to Air Bag/Front Seat Belt
Pretensioner System Warning Beep on
page 7-41.
(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 in accordance with the total seated
weight on the front passenger seat.
For details, refer to the front passenger
seat weight sensors (page 2-72).

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, th e 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.
WA R N I N G
Wear seat belts only as recommended in
this owner's manual:
Incorrect positioning of the seat belts is
dangerous. Without pr oper positioning, the
pretensioner and load limiting systems
cannot provide adequate protection in an
accident and this could result in serious
injury. For more deta ils about wearing seat
belts, refer to "Fastening the Seat Belt"
(page 2-26).

Do not leave a seat belt extender
connected to the buckle:
Leaving a seat belt extender connected to
the buckle without using the seat belt is
dangerous. When the seat belt extender is
connected to the driver's seat belt buckle
(or front passenger's seat belt buckle), the
SRS driver's (or front passenger's) air bag
system will determine that the driver (or
front passenger) is wearing the seat belt
even if the driver (or front passenger) is not
wearing it. This condition could cause the
driver's (or front passenger's) air bag to not
activate correctly and result in death or
serious injury in the event of collision.
Always wear the seat belt with the seat belt
extender.
Do not use the seat belt extender when
installing a child-restraint system on the
front or rear passenger seat:
Using a seat belt extender to fasten a
child-restraint system on any seat is
dangerous. Always follow the
child-restraint system manufacturer's
installation instructions and never use a
seat belt extender.
NOTE
When not in use, remove the seat belt
extender and store it in the vehicle. If the
seat belt extender is left connected, the
seat belt extender might get damaged as it
will not retract with the rest of the seat belt
and can easily fall out of the door when
not in use and be damaged. In addition,
the seat belt warning light will not
illuminate and function properly.

(Mexico)
NEVER use a rearward facing child restraint
on a seat protected by an ACTIVE AIRBAG in
front of it, DEATH or SERIOUS INJURY to the
CHILD can occur.
Vehicles with a front passenger air bag
have the following warning label. The
warning label reminds you not to put a
rear-facing child-restraint system on the
front passenger seat at any time.

(Except Mexico)
Vehicles with a front passenger air bag
have the following warning label. The
warning label reminds you not to put a
rear-facing child-restraint system on the
front passenger seat at any time.
Do not install a front-facing child-restraint
system on the front passenger seat unless it
is unavoidable:
In a collision, the force of a deploying air
bag could cause serious injury or death to
the child. If installing a front-facing
child-restraint system on the front
passenger seat is unavoidable, move the
front passenger seat as far back as
possible.
Seating a child in a child-restraint system
on the front passenger seat is dangerous
under certain conditions (With Front
Passenger Occupant Classification System):
Your vehicle is equipped with front
passenger seat weight sensors. Even with
the front passenger seat weight sensors, if
you must use the front passenger seat to
seat a child, using a child-restraint system
on the front passenger seat under the
following conditions increases the danger
of the front passenger air bag deploying
and could result in serious injury or death
to the child.
The front passenger air bag deactivation
indicator light does not illuminate when
seating a child in the child-restraint
system.
