3. Place the child-restraint system on theseat without putting your weight on the
seat and fasten the seat belt. See the
manufacturer's instructions on the
child-restraint system for belt routing
instructions.
4. To get the retractor into the automatic locking mode, pull the shoulder belt
portion of the seat belt until the entire
length of the belt is out of the retractor.
5. Push the child-restraint system firmly into the vehicle seat. Be sure the belt
retracts as snugly as possible. A
clicking noise from the retractor will be
heard during retraction if the system is
in automatic locking mode. If the belt
does not lock the seat down tight,
repeat the previous step and also this
one.
NOTE
lInspect this function before each use of the
child-restraint system. You should not be
able to pull the shoulder belt out of the
retractor while the system is in the
automatic locking mode. When you remove
the child-restraint system, be sure the belt
fully retracts to return the system to
emergency locking mode before occupants
use the seat belts.
lFollow the child-restraint system
manufacturer's instructions carefully.
Depending on the type of child-restraint
system, it may not employ seat belts which
are in automatic locking mode.
6. Seat your child safely in the child- restraint system and secure the child
according to the instructions from the
child-restraint system manufacturer. 7.
(With Driver and Front Passenger
Occupant Classification System)
Make sure the front passenger air bag
deactivation indicator light illuminates
after installing a child-restraint system
on the front passenger seat.
If the front passenger air bag
deactivation indicator light does not
illuminate, remove the child-restraint
system, switch the ignition to OFF or
ACC, and then re-install the child-
restraint system.

Do not modify the suspension:Modifying the vehicle suspension is dangerous. If the vehicle's height or the
suspension is modified, the vehicle will be unable to accurately detect a collision
resulting in incorrect or unexpected air bag deployment and the possibility of serious
injuries.
Do not modify a front door or leave any damage unrepaired. Always have an
Authorized Mazda Dealer inspect a damaged front door: Modifying a front door or leaving any damage unrepaired is dangerous. Each front
door has a side crash sensor as a component of the supplemental restraint system. If
holes are drilled in a front door, a door speaker is left removed, or a damaged door is
left unrepaired, the sensor could be adversely affected causing it to not detect the
pressure of an impact correctly during a side collision. If a sensor does not detect a
side impact correctly, the side and curtain air bags and the front seat belt
pretensioner may not operate normally which could result in serious injury to
occupants.
Do not modify the supplemental restraint system: Modifying the components or wiring of the supplemental restraint system is
dangerous. You could accidentally activate it or make it inoperable. Do not make
any modifications to the supplemental restraint system. This includes installing trim,
badges, or anything else over the air bag modules. It also includes installing extra
electrical equipment on or near system components or wiring. An Authorized Mazda
Dealer can provide the special care needed in the removal and installation of front
seats. It is important to protect the air bag wiring and connections to assure that the
bags do not accidentally deploy, the driver seat slide position sensor and front
passenger seat weight sensors are not damaged and that the seats retain an
undamaged air bag connection.
NOTE
lWhen 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.
lShould 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.
lOn some models, a highly-visible label is displayed which warns against the use of rear-facing
child-restraint systems on the front passenger seat.

qFront Passenger Air Bag
The front passenger air bag is mounted in the front passenger dashboard. The inflation
mechanism for the front passenger air bag is the same as the driver's air bag, as mentioned
above.
For more details about air bag deployment, refer to “SRS Air Bag Deployment Criteria ”
(page 2-54).
(With Driver and Front Passenger Occupant Classification System)
In addition, the front 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 driver and front
passenger occupant classification system (page 2-57).
q Side Air Bagsí
The side air bags are mounted in the outboard sides of the front seatbacks.
When the air bag crash sensors detect a side impact of greater than moderate force, the
system inflates the side air bag only on the side in which the vehicle was hit. The side air
bag inflates quickly to reduce injury to the driver or front passenger's chest caused by
directly hitting interior parts such as a door or window.
For more details about air bag deployment, refer to “SRS Air Bag Deployment Criteria ”
(page 2-54).

In addition, the front passenger side air bag 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 2-57).
qCurtain Air Bagsí
The curtain air bags are mounted in the front and rear window pillars, and the roof edge
along both sides.
When the air bag crash sensors detect a side impact of greater than moderate force, the
curtain air bag inflates quickly and helps to reduce injury mainly to the rear outboard
passenger's head caused by directly hitting interior parts such as a door or window.
For more details about air bag deployment, refer to “SRS Air Bag Deployment Criteria ”
(page 2-54).
In a side impact:
Greater than moderate impact to one side of the vehicle will cause the curtain air bag on
that side only to inflate.
The side and curtain air bags will deploy only on the side the
vehicle receives the force of the impact.

First, please read“Supplemental Restraint System (SRS) Precautions” (page 2-44)
carefully.
q Driver Seat Slide Position Sensor
Your vehicle is equipped with a driver seat slide position sensor as a part of the
supplemental restraint system. The sensor is located under the driver seat. The sensor
determines whether the driver seat is fore or aft of a reference position and sends the seat
position to the diagnostic module (SAS unit). The SAS unit is designed to control the
deployment of the driver air bag depending on how close the driver seat is to the steering
wheel.
The air bag/front seat belt pretensioner system warning light flashes if the sensor has a
possible malfunction (page 2-53).
qFront 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 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 front passenger air bag, the
system deactivates the front passenger front and side 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 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 seat belt
pretensioner system will not deploy.

The curtain air bag is ready for inflating despite the chart above.
If the front passenger air bag deactivation indicator light does not illuminate when the
ignition is switched ON and does not illuminate as indicated in the above chart, do not
allow a 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.
