WARNING
Seat belts must be worn in air bag equipped vehicles: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 the first collision with frontal, near frontal or side forces
that are at least moderate. Vehicle occupants should always wear seat belts.
Children should not ride in the front passenger 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.
Never use a rear-facing child-restraint system in the front seat with an air bag that
could deploy: Rear-facing child-restraint systems on the front seat are particularly dangerous even
though you may feel assured that a front passenger air bag will not deploy based on
the fact that the front passenger air bag deactivation indicator light illuminates.
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.
Do not sit too close to the driver and front passenger air bags:Sitting too close to the driver and front passenger air bag modules or placing hands
or feet on them is extremely dangerous. The driver and front passenger air bags
inflate with great force and speed. Serious injuries could occur if someone is too
close. The driver should always hold onto only the rim of the steering wheel. The
front seat passenger should keep both feet on the floor. Front seat occupants should
adjust their seats as far back as possible and always sit upright against the
seatbacks with seat belts worn properly.

Do not increase 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 lbs) 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 may cause serious injury. Increasing the total seated
weight on the front passenger seat beyond the total seated weight of approximately
30 kg (66 lbs) 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:
ØLuggage or other items are placed on the seat with the child in the child-restraint
system.
Ø A rear passenger or luggage push or pull down on the front passenger seatback.
Ø A rear passenger steps on the front passenger seat rails with their feet.
Ø Luggage or other items are placed on the seatback or hung on the head restraint.
Ø The seat is washed.
Ø Liquids are spilled on the seat.
Ø The front passenger seat is moved backward, pushing into luggage or other items
placed behind it.
Ø The front passenger seatback contacts the rear seat.
Ø Luggage or other items are placed between the front passenger seat and driver
seat.
Ø Any accessories which might increase the total seated weight on the front
passenger seat are attached to the front passenger seat.
The front passenger front and side air bags and seat belt pretensioner systems will
deactivate if the total seated weight on the front passenger seat is less than
approximately 30 kg (66 lbs) and they will reactivate when the weight exceeds
approximately 42 kg (93 lbs).
CAUTION
Ø To assure proper deployment of the front air bag and to prevent damage to the
sensors in the front seat bottoms:
ØDo not place sharp objects on the front seat bottoms or leave heavy luggage on
them.
ØDo not spill any liquids on the front seats or under the front seats.
Ø To allow the sensors to function properly, always perform the following:
ØAdjust the front seats as far back as possible and always sit upright against the
seatbacks with seat belts worn properly.
ØIf 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
2-35).

NOTElThe 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.
lThe 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.
lThe front passenger air bag deactivation indicator light may illuminate for 10 seconds if the total
seated weight on the front passenger seat changes.
lIf 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.
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.
qHow the Side and Curtain Air Bags Workí
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. However, the side air bag system for the front
passenger is designed to only deploy in accordance with the total seated weight on the front
passenger seat, however the curtains are not deactivated.
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.
The side and curtain air bags will deploy only on the
side the vehicle receives the force of the impact.

qLuggage Compartment
WARNING
Do not place anything on top of 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
such as a rollover. Tie down all heavy
objects, whether luggage or cargo,
using the tie down hooks.
Make sure luggage and cargo is
secured before driving: Not securing cargo while driving is
dangerous as it could move or be
crushed during sudden braking or a
collision and cause injury.
CAUTION
Make sure the luggage compartment
cover is firmly secured. If it is not
firmly secured, it could unexpectedly
disengage resulting in injury.
