child-restraint system moves it could result
in death or injury to the child.
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.
▼ If You Must Use the Front Seat for
Children
If you cannot put all children in the rear
seat, at least put the smallest children in
the rear and be sure the largest child up
front uses the shoulder belt over the
shoulder.
NEVER put a rear-facing child-restraint
system on the front passenger seat whether
your vehicle is equipped with an occupant
classification sensor or not.
This seat is also not set up for tethered
child-restraint systems,
put them in one of
the rear seat positions set up with tether
anchors.
Likewise the ISOFIX/LATCH
*1
child-restraint system cannot be secured in
the front passenger's seat and should be
used in the rear seat.
Do not allow anyone to sleep against the
side window since your vehicle has side
and curtain air bags, it could cause serious
injuries to an out of position occupant. As
children more often sleep in cars, it is
better to put them in the rear seat. If
installing the child-restraint system on the
front seat is unavoidable, follow these
instructions when using a front-facing
child-restraint syst em in the front
passenger's seat.

▼Using ISOFIX Lower Anchor (Mexico)
/Using LATCH Lower Anchor (Except
Mexico)
Your Mazda is equipped with ISOFIX/LATCH*1 lower anchors for attachment of specially
designed ISOFIX/LATCH
*1 child-restraint systems in the rear seats. Both anchors must be
used, otherwise the seat will bounce around and put the child in danger. Most ISOFIX/
LATCH
*1 child-restraint systems must also be used in conjunction with a tether to be
effective. If they have a tether you must use it to better assure your child's safety.
WARNING
Follow the manufacturer's instructions for the use of the child-restraint system:
An unsecured child-restraint system is dangerous . In a sudden stop or a collision it could move
causing serious injury or death to the child or other occupants. Make sure the child-restraint
system is properly secured in place accordin g to the child-restraint system manufacturer's
instructions.
Never attach two child-restraint systems to the same ISOFIX/LATCH
*1 lower anchor:
Attaching two child-restraint systems to the same ISOFIX/LATCH
*1 lower anchor is dangerous.
In a collision, one anchor may not be strong enough to hold two child-restraint system
attachments, and it may break, causing serious inju ry or death. If you use the seat position for
another child-restraint system when an outboard ISOFIX/LATCH
*1 position is occupied, use
the center seat belts instead, and the tether if tether-equipped.
Make sure the child-restraint system is properly secured:
An unsecured child-restraint system is dangerous . In a sudden stop or a collision it could move
causing serious injury or death to the child or other occupants. Follow the child-restraint
system manufacturer's instructions on belt routin g to secure the seat just as you would with a
child in it so that nobody is tempted to put a child in an improperly secured seat later on.
When not in use, remove it from the vehicle or fasten it with a seat belt, or attach it to BOTH
ISOFIX/LATCH
*1 lower anchors for ISOFIX/LATCH*1 child-restraint systems.

system from being securely attached to the ISOFIX/LATCH
*1 lower anchors and the
child-restraint system is installed improperly, the child-restraint system could move in a
sudden stop or collision causing serious injury or death to the child or other occupants. When
installing the child-restraint system, make sure there are no seat belts or foreign objects near
or around the ISOFIX/LATCH
*1 lower anchors. Always follow the child-restraint system
manufacturer's instructions.

child-restraint systems can be placed in the
center position and will reach the nearest
ISOFIX/LATCH
*1 lower anchors which
are 360 mm (14.2 in) apart. ISOFIX/
LATCH
*1 compatible child-restraint
systems (with attachments on belt
webbing) can be used at this seating
position only if the child-restraint system
manufacturer's instructions state that the
child-restraint system can be installed to
ISOFIX/LATCH
*1 lower anchors that are
360 mm (14.2 in) apart. Do not attach two
child-restraint systems to the same
ISOFIX/LATCH
*1 lower anchor. If your
child-restraint system has a tether, it must
also be used for your child's optimum
safety.

The procedure for installation on the rear
outboard seats is the same.

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.
