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 7-31.
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.

Do not place luggage or other objects
under the front seats:
Placing luggage or other objects under the
front seats is dangerous. The components
essential to the supplemental restraint
system could be damaged, and in the event
of a side collision, the appropriate air bags
may not deploy, which could result in
death or serious injury. To prevent damage
to the components essential to the
supplemental restraint system, do not
place luggage or other objects under the
front seats.
Do not operate a vehicle with damaged air
bag/seat belt pretensioner system
components:
Expended or damaged air bag/seat belt
pretensioner system components must be
replaced after any collision which caused
them to deploy or damage them. Only a
trained Authorized Mazda Dealer can fully
evaluate these systems to see that they will
work in any subsequent accident. Driving
with an expended or damaged air bag or
pretensioner unit will not afford you the
necessary protection in the event of any
subsequent accident which could result in
serious injury or death.
Do not remove interior air bag parts:
Removing any components such as the
front seats, front dashboard, the steering
wheel or parts on the front and rear
window pillars and al ong the roof edge,
containing air bag parts or sensors is
dangerous. These parts contain essential
air bag components. The air bag could
accidentally activate and cause serious
injuries. Always have an Authorized Mazda
Dealer remove these parts.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 Deal er 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 system modified
to accommodate a person with certain
medical conditions in accordance with a
certified physician, contact an
Authorized Mazda Dealer, refer to
“Customer Assistance (U.S.A.)” (page
8-2).
When an air bag deploys, a loud
inflation 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.

▼Front Passenger Seat Weight
Sensors
Your vehicle is equipped with a front
passenger seat weight sensors as a part of
the supplemental restraint system. These
sensors are located under both of the front
passenger seat rails. These sensors
determine the total
seated weight on the
front passenger seat and monitor the seat
belt buckle for the front passenger seat.
The SAS unit is designed to prevent the
front passenger front and side air bags and
knee air bags, and seat belt pretensioner
system from deploying if the front
passenger air bag deactivation indicator
light illuminates.
To reduce the chance of injuries caused by
deployment of the fr ont passenger air bag,
the system deactivates the front passenger
front and side air bags and knee air bags,
and also the seat belt pretensioner system
when the front passenger air bag
deactivation indicator light illuminates.
Refer to the following table for the front
passenger air bag deactivation indicator
light illumination conditions.

This system shuts off the front passenger
front and side air bags and knee air bags,
and seat belt pretensioner system, so make
sure the front passenger air bag
deactivation indicator light illuminates
according to the following table.

The air bag/front seat belt pretensioner
system warning light flashes and the front
passenger air bag deactivation indicator
light illuminates if the sensors have a
possible malfunction. If this happens, the
front passenger front and side air bags and
knee air bags, and seat belt pretensioner
system will not deploy.
Front passenger air bag deactivation
indicator light
This indicator light illuminates to remind
you that the front passenger front and side
air bags and knee air bags, and seat belt
pretensioners will not deploy during a
collision.
If the front passenger weight sensors are
normal, the indicator light illuminates
when the ignition is switched ON. The
light turns off after a few seconds. Then,
the indicator light illuminates or is off
under the following conditions:

child to sit in the front passenger seat and
consult an Authorized Mazda Dealer as
soon as possible. The system may not
work properly in an accident.
WA R N I N G
Do not decrease the total seated weight on
the front passenger seat:
When an adult or large child sits on the
front passenger seat, decreasing the total
seated weight on the front passenger seat
required for air bag deployment is
dangerous. The front passenger seat
weight sensors will de tect the reduced total
seated weight condition and the front
passenger front and side air bags and knee
air bags, and the seat belt pretensioner
system will not deploy during an accident.
The front passenger will not have the
supplementary protection of the air bag,
which could result in serious injury.
Decreasing the total seated weight on the
front passenger seat could result in an air
bag not deploying under the following
conditions, for example:
