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 the 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
2-67).

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.
(With Front Passenger Occupant
Classi fication 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 fficient
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 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).

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.

Properly dispose of the air bag
system:
Improper disposal of an air bag or a
vehicle with live air bags in it can be
extremely dangerous. Unless all safety
procedures are followed, injury could
result. Have an Authorized Mazda
Dealer safely dispose of the air bag
system or scrap an air bag equipped
vehicle.
NOTE
If it becomes necessary to have the
components or wiring system for the
supplementary restraint systemmodi fied to accommodate a person
with certain medical conditions in
accordance with a certi fied
physician, contact an Authorized
Mazda Dealer, refer to “Customer
Assistance (U.S.A.)” (page 8-2).
When an air bag deploys, a loud in flation noise can be heard and
some smoke will be released.
Neither is likely to cause injury,
however, the texture of the air bags
may cause light skin injuries on body
parts not covered with clothing
through friction.
Should you sell your Mazda, we urge
you to tell the new owner of its air
bag systems and that familiarization
with all instructions about them,
from the Owner's Manual, is
important.
This highly-visible label is displayed
which warns against the use of a
rear-facing child-restraint system on
the front passenger seat.
