adjusted:
Driving with the head restraints
adjusted too low or removed is
dangerous. With no support behind
your head, your neck could be
seriously injured in a collision.
▼
Height Adjustment

center is even with the top of the
passenger's ears.

To raise a head restraint, pull it up to
the desired position.
To lower the head restraint, press the
stop-catch release, then push the head

CAUTION
When installing a head restraint,
make sure that it is installed correctly
with the front of the head restraint
facing forward. If the head restraint is
installed incorrectly, it could detach
from the seat during a collision and
result in injury.
 The head restraints on each of the
front and rear seats are specialized to
each seat. Do not switch around the
head restraint positions. If a head
restraint is not installed to its correct
seat position, the e ffectiveness of the
head restraint during a collision will
be compromised which could cause
injury.

Seat Belt Precautions
▼Seat Belt Precautions
Seat belts help to decrease the
possibility of severe injury during
accidents and sudden stops. Mazda
recommends that the driver and all
passengers always wear seat belts.

(Mexico)
All the seats have lap/shoulder belts.
These belts have retractors with inertia
locks that keep them out of the way
when not in use. The locks allow the
belts to remain comfortable on users,
but they will lock in position during a
collision.

(Except Mexico)
All of the seat belt retractors are
designed to keep the lap/shoulder
belts out of the way when not in use.
The driver's seat belt has no provisions
for child-restraint systems and has only
an emergency locking mode. The
driver may wear it comfortably, and it
will lock during a collision.
However, the front passenger's seat
and all rear lap/shoulder belt
retractors operate in two modes:
emergency locking mode, and for
child-restraint systems, automatic
locking mode. While we recommend
you put all children in the rear seats, if
you must use the front passenger seat
for a child, slide the front passenger
seat as far back as possible and make
sure any child-restraint system is
secured properly.
WARNING
Always wear your seat belt and make
sure all occupants are properly
restrained:
Not wearing a seat belt is extremely
dangerous. During a collision,
occupants not wearing seat belts could
hit someone or things inside the
vehicle or even be thrown out of the
vehicle. They could be seriously injured
or even killed. In the same collision,
occupants wearing seat belts would be
much safer.
Do not wear twisted seat belts:
Twisted seat belts are dangerous. In a
collision, the full width of the belt is
not available to absorb the impact.
This puts more force on the bones
beneath the belt, which could cause
serious injury or death. So, if your seat
belt is twisted, you must straighten the
seat belt to remove any twists and to
allow the full width of the belt to be
used.
Never use one seat belt on more than
one person at a time:
Using one seat belt for more than one
person at a time is dangerous. A seat
belt used in this way cannot spread the
impact forces properly and the two
passengers could be crushed together
and seriously injured or even killed.
Never use one belt for more than one
person at a time and always operate
the vehicle with each occupant
properly restrained.

Child-RestraintPrecautions
▼ Child-Restraint Precautions
Mazda strongly urges the use of
child-restraint systems for children
small enough to use them.

You are required by law to use a
child-restraint system for children in
the U.S. and Canada.
Check your local and state or
provincial laws for speci
fic
requirements regarding the safety of
children riding in your vehicle.

Whatever child-restraint system you
consider, please pick the appropriate
one for the age and size of the child,
obey the law and follow the
instructions that come with the
individual child-restraint system.

A child who has outgrown
child-restraint systems should sit in the
rear and use seat belts, both lap and
shoulder. If the shoulder belt crosses
the neck or face, move the child closer
to the center of the vehicle in the
outboard seats, and towards the
buckle on the right if the child is seated
on the center seat.

Statistics con firm that the rear seat is
the best place for all children up to 12
years of age, and more so with a
supplemental restraint system (air
bags).

A rear-facing child-restraint system
should NEVER be used on the front
seat with the air bag system activated.
The front passenger's seat is also the
least preferred seat for other
child-restraint systems.

(With Front Passenger Occupant
Classi fication System)
To reduce the chance of injuries
caused by deployment of the front
passenger air bag, the front passenger
seat weight sensors occupant
classi fication sensor works as a part of
the supplemental restraint system. This
system deactivates the front passenger
front and side air bags and knee air
bags, and also the front passenger seat
belt pretensioner system when the
front passenger air bag deactivation
indicator light illuminates.

When an infant or small child sits on
the front passenger seat, the system
shuts o ff the front passenger front and
side air bags and knee air bags, and
seat belt pretensioner system, so make
sure the front passenger air bag
deactivation indicator light illuminates.

Even if the front passenger air bag is
shut o ff, Mazda strongly recommends
that children be properly restrained
and child-restraint systems of all kinds
are properly secured on the rear seats
which are the best place for children.

For more details, refer to "Front
passenger seat weight sensors" (page
2-71).

The front passenger air bag
deactivation indicator light does not
illuminate when seating a child in the
child-restraint system.
 Luggage or other items are placed on
the seat with the child in the
child-restraint system.
 A rear passenger or luggage pushing
or pulling down on the front
passenger seatback.
 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.
 An electric device is put on the front
passenger's seat.
 An additional electrical device, such
as a seat warmer is installed to the
surface of the front passenger seat.
 Any accessories, which might
increase the total seated weight on
the front passenger seat, are
attached to the front passenger seat.
The designated positions with seat
belts on the rear seats are the safest
places for children. Always use seat
belts and child restraints.Do not allow a child or anyone to
lean over to or against the side
window of a vehicle with side and
curtain air bags:
It is dangerous to allow anyone to lean
over to or against the side window, the
area of the front passenger seat, the
front and rear window pillars and the
roof edge along both sides from which
the side and curtain air bags deploy,
even if a child-restraint system is used.
The impact of in flation from a side or
curtain air bag could cause serious
injury or death to an out of position
child. Furthermore, leaning over to or
against the front door could block the
side and curtain air bags and eliminate
the advantages of supplemental
protection. Because the front seats are
equipped with fron t air bags, the rear
seat is always a better location for
children. Take special care not to allow
a child to lean over to or against the
side window, even if the child is seated
in a child-restraint system.
Never use one seat belt on more than
one person at a time:
Using one seat belt for more than one
person at a time is dangerous. A seat
belt used in this way cannot spread the
impact forces properly and the two
passengers could be crushed together
and seriously injured or even killed.
Never use one belt for more than one
person at a time and always operate
the vehicle with each occupant
properly restrained.
CAUTION
A seat belt or child-restraint system can
become very hot in a closed vehicle
during warm weather. To avoid burning
yourself or a child, check them before
you or your child touches them.
