Always remove the head restraint and
install child-restraint system (except when
installing a backless booster seat):
Installing a child-restraint system without
removing the head restraint is dangerous.
The child-restraint system cannot be
installed correctly which may result in
death or injury to the child in a collision.
Always install the head restraint and adjust
it to the appropriate position after
removing the child-restraint system:
Driving with the head restraint removed is
dangerous as impact to the occupant's
head cannot be prevented during
emergency braking or in a collision, which
could result in a serious accident, injury or
death.
Refer to Head Restraints on page 2-17.
Front Passenger's Seat Child-Restraint
System Installation (With Front
Passenger Occupant Classification
System)
1. Make sure the ignition is switched off.
2. Slide the seat as far back as possible.
3. Remove the head restraint. However,when installing a backless booster seat,
always install the vehicle head restraint
to the seat where the backless booster
seat is installed.
4. 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.
5. 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.
6. Push the child-rest raint 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 lo cking mode. If the
belt does not lock the seat down tight,
repeat the previous step and also this
one.
NOTE
Inspect 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.
Follow 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.
7. Seat your child safely in the child-restraint system and secure the
child according to the instructions

from the child-restraint system
manufacturer.
8. Switch the ignition ON and 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, and
then re-install the child-restraint
system (page 2-66).
WA R N I N G
Do not seat a child in a child-restraint
system on the front passenger seat if the
front passenger air bag deactivation
indicator light does not illuminate:
While it is always better to install any
child-restraint system on the rear seat, it is
imperative that a child-restraint system
ONLY be used on the front passenger seat if
the deactivation indicator light illuminates
when the child is seated in the
child-restraint system (page 2-66). Seating
a child in a child-restraint system installed
on the front passenger seat with the front
passenger air bag deactivation indicator
light not illuminated is dangerous. If this
indicator light does not illuminate, this
means that the front passenger front and
side air bags, and seat belt pretensioners
are ready for deployment. If an accident
were to deploy an air bag, a child in a
child-restraint system sitting in the front
passenger seat could be seriously injured or
killed. If the indicator light does not
illuminate after seating a child in a
child-restraint system on the front
passenger seat, seat a child in a
child-restraint system on the rear seat and
consult an Authorized Mazda Dealer as
soon as possible.

Hold the driver in a position which allows better control of the vehicle.

If your vehicle is also equipped with a fr ont passenger occupant classification system,
refer to the Front Passenger Occupant Cla ssification System (page 2-66) for details.
If your vehicle is equipped with a front pass enger occupant classification 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-rest raint system as stipulated by law in every
state and province. In certain states and provinces, larger children must use a child-restraint
system (page 2-30).

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.
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 appropriate air bags can be expected to
inflate
only in the first accident, such as frontal, near frontal
or side collisions 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.

Front Passenger Occupant Classification System*
First, please read "Supplemental Restraint System (SRS) Precautions" (page 2-51) carefully.
▼Front Passenger Occupant
Classification Sensor
Your vehicle is equipped with a front passenger occupant classification sensor as a part of
the supplemental restraint system. This sensor is equipped in the front passenger's seat
cushion. This sensor measures the electrostatic capacity of the front passenger's seat. The
SAS unit is designed to prevent the front pass enger front and side air bags and seat belt
pretensioner system from deploying if the front passenger air bag deactivation indicator
light turns on.
To reduce the chance of injuries caused by de ployment 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 turns on.
Refer to the following table for the front pa ssenger 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 turns on
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.
Front passenger air bag de activation indicator light
This indicator light turns on to remind you that the front passenger front and side air bags
and seat belt pretensioner wi ll not deploy during a collision.
If the front passenger occupant classification sensor is normal, the indicator light turns on
when the ignition is switch ed ON. The light turns off af ter a few seconds. Then, the
indicator light turns on or is off under the following conditions:

indicator light on/off condition chart, do not allow an occupant 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.
WARNING
Do not allow an occupant in the front passenger's seat to sit with a posture which makes it
difficult for the front passenger occupant classification sensor to detect the occupant
correctly:
Sitting in the front passenger's seat with a posture which makes it difficult for the front
passenger occupant classification sensor to dete ct the occupant correctly is dangerous. If the
front passenger occupant classification sensor cannot detect the occupant sitting on the front
passenger's seat correctly, the front passeng er front and side air bags and pretensioner
system may not operate (non-deploy) or they may operate (deploy) accidentally. The front
passenger will not have the supplementary prot ection of the air bags or the accidental
operation (deployment) of the air bags could result in serious injury or death.
Under the following conditions, the front passenger occupant classification sensor cannot
detect a passenger sitting on the front passenger's seat correctly and the deployment/
non-deployment of the air bags cannot be controlled as indicated in the front passenger air
bag deactivation indicator light on/off condition chart. For example:
