If your vehicle is also equipped with a front passenger occupant classification system,
refer to the Front Passenger O ccupant Classification System (pa ge 2-68) for details.
If your vehicle is equipped with a front passenger occupant cla ssification system, the front
passenger air bag deactivation indicator light illuminates for a specified time after the
ignition is switched ON.


Small children must be protected by a child-restraint system as stipulated by law in every
state and province. In certain states and provinces, larger chi ldren must use a child-restraint
system (page 2-31).

Carefully consider whic h child-restraint system is necessary fo r your child and follow the
installation directions in this Owner's Manual as well as the c hild-restraint system
manufacturer's instructions.
WA R N I N G
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 appr opriate air bags can be expected to inflate
only in the first accident, such as frontal, near frontal or side collision s or roll-over accidents
that are at least moderate. Vehicle occu pants 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. A sleeping child is more likely to lean
against the door and be hit by the side air ba g in moderate collision to the front-passenger
side of the vehicle. Whenever possible, always secure a child 12 years and under on the rear
seats with an appropriate child-restrain t system for the child's age and size.

CAUTION
 To assure proper deployment of the front air bag and to prevent damage to the sensor in
the front seat cushion:
 Do not place sharp objects on the front seat cushion or leave heavy luggage on them.
 Do not spill any liquids on the fr ont seats or under the front seats.
 To allow the sensors to function pr operly, always perform the following:
 Adjust the front seats as far back as possibl e and always sit upright against the seatbacks
with seat belts worn properly.
 If you place your child on the front passe nger seat, secure the child-restraint system
properly and slide the front passenger seat as far back as possible (page 2-44).
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 turn on repeatedly if luggage
or other items are put on the front passenger se at, or if the temperature of the vehicle's
interior changes suddenly.
The front passenger air bag deactivation indicator light may turn on for 10 seconds if the
electrostatic capacity on the front passenger seat changes.
The air bag/front seat belt pr etensioner system warning light might turn on if the front
passenger seat receives a severe impact.
If the front passenger air bag deactivation indicator light does not turn on after installing
a child-restraint system on the front passenger seat, first, re-install your child-restraint
system according to the procedure in this owner's manual. Then, if the front passenger air
bag deactivation indicator light still does not turn on, install the child-restraint system on
the rear seat and consult an Authorized Mazda Dealer as soon as possible.
If the front passenger air bag deactivation indicator light turns on when an occupant is
seated directly in the front passenger seat , have the passenger re-adjust their posture by
sitting with their feet on the floor, and then re-fastening the seat belt. If the front
passenger air bag deactivation indicator light remains turned on, move the passenger to
the rear seat. If sitting in the rear seat is not possible, slide the front passenger seat as far
back as possible. Consult an Authorized Mazda Dealer as soon as possible.

Door Locks
WA R N I N G
Always take all children and pets with you
or leave a responsible person with them:
Leaving a child or a pet unattended in a
parked vehicle is dangerous. In hot
weather, temperatures inside a vehicle can
become high enough to cause brain
damage or even death.
Do not leave the key in your vehicle with
children and keep them in a place where
your children will not find or play with
them:
Leaving children in a vehicle with the key is
dangerous. This could result in someone
being badly injured or even killed.
Keep all doors locked when driving:
Unlocked doors in a moving vehicle are
dangerous. Passengers can fall out if a
door is accidentally opened and can more
easily be thrown out in an accident.
Always close all the windows and
moonroof, lock the doors and the trunk lid
and take the key with you when leaving
your vehicle unattended:
Leaving your vehicle unlocked is dangerous
as children could lock themselves in a hot
vehicle, which could result in death. Also, a
vehicle left unlocked becomes an easy
target for thieves and intruders.
After closing the doors and the trunk lid,
always verify that they are securely closed:
Doors and the trunk lid not securely closed
are dangerous, if the vehicle is driven with
a door and the trunk lid not securely closed,
the door and the tr unk lid could open
unexpectedly resulting in an accident.
Always confirm the safety around the
vehicle before opening a door and the
trunk lid:
Suddenly opening a door and the trunk lid
is dangerous. A passing vehicle or a
pedestrian could be hit and cause an
accident.
CAUTION
 Always confirm the conditions around
the vehicle before opening/closing the
doors and the trunk lid and use caution
during strong winds or when parked on
an incline. Not being aware of the
conditions around the vehicle is
dangerous because fingers could get
caught in the door and the trunk lid or a
passing pedestrian could be hit, resulting
in an unexpected accident or injury.
NOTE
Always stop the engine and lock the
doors. In addition, to prevent theft of
valuables, do not leave them inside the
cabin.
If the key is left in the following areas
and you leave the vehicle, the doors may
be locked depending on the radio wave
conditions even if th e key is left in the
vehicle.
Around the dashboard
