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.
NOTE
Your Mazda is equipp ed with ISOFIX/LATCH*1 lower anchors for attachment of specially
designed ISOFIX/LATCH
*1 child-restraint systems on the rear seats. When using these
anchors to secure a child-rest raint system, refer to "Using IS OFIX Lower Anchor (Mexico)/

Installing Child-RestraintSystems
Accident statistics reveal that a child is
safer in the rear seat. The front passenger's
seat is clearly the worst choice for any
child under 12, and with rear-facing
child-restraint systems it is clearly unsafe
due to air bags.

NOTE
Even if your vehicle is equipped with front
passenger occupant classification sensor
(page 2-66), which automatically
deactivates the front passenger air bag, a
rear seat is the safest place for a child of
any age or size.

Some child-restrain t systems now come
with tethers and therefore must be
installed on the seats that take tethers to be
effective. In your Mazda, tethered
child-restraint systems can only be
accommodated in the three positions on
the rear seat.

Some child-restraint systems also employ
specially designed ISOFIX/LATCH
*1
attachments; refer to "Using ISOFIX
Lower Anchor (Mexico)/Using LATCH
Lower Anchor (Except Mexico)" (page
2-47).

Tethered Child-Restraint Systems Work
Only on Tether-Equipped Rear Seats:
Installation of a tether equipped
child-restraint system in the front
passenger's seat defeats the safety design
of the system and will result in an increased
chance of serious injury if the
child-restraint system goes forward
without benefit of being tethered.
Place tether equipped child-restraint
systems where there are tether anchors.
▼Anchor Bracket
Anchor brackets for securing
child-restraint systems are equipped in the
vehicle. Locate each anchor position using
the illustration.
To install a child-restraint system, remove
the head restraint. Always follow the
instruction manual accompanying the
child-restraint system.

WARNING
Always attach the tether strap to the
correct tether anchor position:
Attaching the tether strap to the incorrect
tether anchor position is dangerous. In a
collision, the tether strap could come off
and loosen the child-restraint system. If the
child-restraint system moves it could result
in death or injury to the child.

▼ Using Automatic Locking Mode
(Except Mexico)
Follow these instructions when using a
child-restraint system, unless you are
attaching a LATCH-equipped
child-restraint system
to the rear LATCH
lower anchors. Refer to “Using LATCH
Lower Anchor” (page 2-47).
NOTE
Follow the child-restraint system
manufacturer's instru ctions carefully. If
you are not sure whether you have a
LATCH system or tether, check in the
child-restraint system manufacturer's
instructions and follow them accordingly.
Depending on the type of child-restraint
system, it may use LATCH system instead
of seat belts or if the belt goes across the
child's chest, may recommend against
using automatic locking mode.
1. Make sure the seatback is securely latched by pushing it back until it is
fully locked.
2. Remove the head restraint. However,
when installing a backless booster seat,
always install the vehicle head restraint
to the seat where the backless booster

manufacturer's instructions to hook
and tighten the tether strap.
WA R N I N G

Use the tether and tether anchor only for a
child-restraint system:
Using the tether or tether anchor to secure
anything but a child-restraint system is
dangerous. This could weaken or damage
the tether or tether anchor and result in

▼ 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.
