SRS Air Bags
Form No. 8S18-EA-03I
Small children should be protected by a child-restraint system. In certain regions, larger
children must use a child-restraint system (page 2-21).
Carefully consider which child-restraint system is necessary for your child and follow the
installation directions in this Owner’s Manual as well as the child-restraint system
manufacturer’s instructions.
Air Bags without Seat Belts:
Depending only on the air bags for protection during an accident is dangerous.
Alone, air bags may not prevent serious injuries. The appropriate air bags can be
expected to inflate only in collisions with frontal, near frontal or side forces that are at
least moderate. Vehicle occupants should always wear seat belts.
Child in the Front Seat:
Placing a child, 12 years or under, in the front seat is dangerous. The child could be
hit by a deploying air bag and be seriously injured or even killed. Even if the front
passenger air bag deactivation indicator light illuminates, always move the front
passenger seat as far back as possible. A sleeping child is more likely to lean against
the door and be hit by the side air bag in a moderate, right-side collision. Whenever
possible, always secure a child 12 years and under on the rear seat with an
appropriate child-restraint system for the child’s age and size.
Rear-Facing Child-Restraint System:
Rear-facing child-restraint systems on the front seat are particularly dangerous.
The child-restraint system can be hit by a deploying air bag and moved violently
backward resulting in serious injury or death to the child. Even though you may feel
assured that the front passenger air bag will not deploy based on the fact that the front
passenger air bag deactivation indicator light illuminates, NEVER use a rear-facing
child-restraint system in the front seat with an air bag that could deploy even in a
moderate collision.

Increasing the Total Seated Weight on the Front Passenger Seat:
When an infant or small child sits on the front passenger seat, increasing the total
seated weight on the front passenger seat from the total seated weight of
approximately 30 kg (66 lb) is dangerous. The front passenger seat weight sensors will
detect the increased total seated weight, which could result in the unexpected
deployment of the front passenger front and side air bags and seat belt pretensioner
system in an accident and serious injury. Increasing the total seated weight on the
front passenger seat from the total seated weight of approximately 30 kg (66 lb) could
result in the front passenger front and side air bags and seat belt pretensioner system
deployment in an accident under the following conditions, for example:
•Luggage or other items are placed on the seat with the child in the child-restraint
system.
•A rear passenger or luggage push or pull down on the front passenger seatback.
•A rear passenger steps on the front passenger seat rails with the feet.
•Luggage or other items are placed on the seatback or hung on the head restraint.
•The seat is washed.
•Liquids are spilled on the seat.
•The front passenger seat is moved backward, pushing into luggage or other items
placed behind it.
•The front passenger seatback contacts the rear seat.
•Luggage or other items are placed between the front passenger seat and driver seat.
•Any accessories which might increase the total seated weight on the front
passenger seat are attached to the front passenger seat.
•To assure proper deployment of the front air bag and to prevent damage to the sensors
in the front seat bottoms:
Do not place sharp objects on the front seat bottoms or leave heavy luggage on them.
Do not spill any liquids on the front seats or under the front seats.
•To allow the sensors to function properly, always perform the following:
Adjust the front seats as far back as possible and always sit upright against the
seatbacks with seat belts worn properly.
If you place your child on the front passenger seat, secure the child-restraint system
properly and slide the front passenger seat as far back as possible (page 2-29).

Driver and front passenger buckle switches
The buckle switches on the front seat belts detect whether or not the front seat belts are
securely fastened and further control the deployment of the air bags on the front seats.

How the Side and Curtain Air Bags Work*
When air bag crash sensors detect a side impact of greater than moderate force, an
electrical current is sent to the inflators.
Gases are produced to inflate the side and curtain air bags and after the inflation, the side
and curtain air bags quickly deflate.
The side and curtain air bags will function only once. After that, the side and curtain air
bags will not work again and must be replaced.
Only an Authorized Mazda Dealer can
replace the systems.
NOTE
•The system requires about 10 seconds to alternate between turning the front
passenger front and side air bags and seat belt pretensioner system on or off.
•The front passenger air bag deactivation indicator light may illuminate repeatedly if
luggage or other items are put on the front passenger seat, or if the temperature of the
vehicle’s interior changes suddenly.
•The front passenger air bag deactivation indicator light may illuminate for 10 seconds
if the total seated weight on the front passenger seat changes.
•
If the front passenger air bag deactivation indicator light does not illuminate after
installing a child-restraint system on the front passenger seat, install the child-restraint
system on the rear seat and consult an Authorized Mazda Dealer as soon as possible.
To prevent damage to the side and curtain air bag wiring, don’t place luggage or other
objects under the front seats.
The side air bag will deploy only on the side
the vehicle receives the force of the impact.The curtain air bag will deploy only on the side
the vehicle receives the force of the impact.

Placing Cargo on the Cover:
Placing luggage or other cargo on top
of the luggage compartment cover is
dangerous. During sudden braking or
a collision, the cargo could become a
projectile that could hit and injure
someone. The vehicle has a light
weight luggage compartment cover to
keep the contents of your luggage
area out of sight; it will not retain
heavy objects that are not tied down in
an accident like a rollover. Tie down
all heavy objects, whether luggage or
cargo, using the tie down hooks.
Don’t place anything on top of the
cover.
Not Securing Luggage and Cargo:
Not securing cargo while driving is
dangerous as it could move or be
crushed during sudden braking or a
collision and cause injury. Make sure
luggage and cargo is secured before
driving.
Make sure the luggage compartment
cover is firmly secured. If it is not
firmly secured, it could unexpectedly
disengage resulting in injury.

Unattended Children and Pets:
Leaving children or animals
unattended in a parked vehicle is
dangerous. Babies left sleeping and
kids who lock themselves in cars or
trunks can die very quickly from heat
prostration. Don’t leave your children
or pets alone in a car at any time.
Don’t leave the car, the rear folding
seats or the trunk unlocked. Always
keep the car from being a tempting
place to play by locking rear seats,
doors and the trunk, and keeping the
keys where children won’t play with
them.
For vehicles equipped with a rear
spoiler, do not lift the trunk lid by the
spoiler. Lifting up the trunk lid by the
rear spoiler could cause damage to the
rear spoiler and the trunk lid.
