Front Seats
WARNING
Do not modify or replace the front
seats:
Modifying or replacing the front seats
such as replacing the upholstery or
loosening any bolts is dangerous. The
front seats contain air bag
components essential to the
supplemental restraint system. Such
modifications could damage the
supplemental restraint system and
result in serious injury. Consult an
Authorized Mazda Dealer if there is
any need to remove or reinstall the
front seats.
Do not drive with damaged front seats:
Driving with damaged front seats is
dangerous. A collision, even one not
strong enough to inflate the air bags,
could damage the front seats which
contain essential air bag components.
If there was a subsequent collision, an
air bag may not deploy which could
lead to injuries. Always have an
Authorized Mazda Dealer inspect the
front seats, front seat belt
pretensioners and air bags after a
collision.
WARNING
Make sure the adjustable components
of a seat are locked in place:
Adjustable seats and seatbacks that
are not securely locked are dangerous.
In a sudden stop or collision, the seat
or seatback could move, causing
injury. Make sure the adjustable
components of the seat are locked in
place by attempting to slide the seat
forward and backward and rocking
the seatback.
qSeat Slide
WARNING
Adjust the driver seat only when the
vehicle is stopped:
Adjusting the driver's seat while the
vehicle is moving is dangerous. The
driver could lose control of the vehicle
and have an accident.
To move a seat forward or backward, raise
the lever and slide the seat to the desired
position and release the lever.

the luggage compartment cover is
dangerous. During sudden braking or
a collision, objects can fly around and
become projectiles that may hit and
injure passengers.
Make sure luggage and cargo is
secured before driving:
Not securing cargo while driving is
dangerous as it could move or be
crushed during sudden braking or a
collision and cause injury.
Make sure the adjustable components
of a seat are locked in place:

WARNING
When returning the seatback to the
upright position, make sure there is no
red indication:
A rear seatback not fully returned and
locked in the upright position is
dangerous. Sudden stops or
maneuvering could cause a seatback
to flip forward suddenly resulting in
injury. If the red indicator is visible on
the back of the rear seatback knob, the
seatback is not locked in the upright
position.

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.
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.
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.
Do not operate a vehicle with a damaged seat belt:
Using a damaged seat belt is dangerous. An accident could damage the belt webbing
of the seat belt in use. A damaged seat belt cannot provide adequate protection in a
collision. Have an Authorized Mazda Dealer inspect all seat belt systems in use during
an accident before they are used again.

qStowing and pulling out the
Center-Rear Position Seat Belt
The center-rear position seat belt can be
stowed using the following procedure.
CAUTION
When stowing the seat belt, make sure
the belt is locked securely into the
recess. If the seat belt is not properly
stowed, it might get caught in the seats
and be damaged.
To stow the seat belt, retract the belt, put
tongues (A) and (C) together and insert
them into the recess.Sedan (Behind head restraint on left
side)

needed, retract the seat belt fully to
convert it back to emergency locking
mode.

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 specific 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 confirm 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 shouldNEVERbe 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.
To reduce the chance of injuries caused by deployment of the front passenger air bag, the
front passenger seat weight sensors work as a part of the supplemental restraint system.
This system deactivates the front passenger front and side air bags and also the front
passenger seat belt pretensioner system when the total seated weight on the front passenger
seat is less than approximately 30 kg (66 lb).
When an infant or small child sits on the front passenger seat, the 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 illuminates.
Even if the front passenger air bag is shut off, 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 2-49).

WARNING
Use the correct size child-restraint system:
For effective protection in vehicle accidents and sudden stops, a child must be
properly restrained using a seat belt or child-restraint system depending on age and
size. If not, the child could be seriously injured or even killed in an accident.
Follow the manufacturer's instructions and always keep the child-restraint system
buckled down:
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
any child-restraint system is properly secured in place according to the child-restraint
system manufacturer's instructions. When not in use, remove it from the vehicle or
fasten it with a seat belt, or latch it down to BOTH LATCH lower anchors for LATCH
child-restraint systems and the corresponding tether anchor.
Always secure a child in a proper child-restraint system:
Holding a child in your arms while the vehicle is moving is extremely dangerous. No
matter how strong the person may be, he or she cannot hold onto a child in a sudden
stop or collision and it could result in serious injury or death to the child or other
occupants. Even in a moderate accident, the child may be exposed to air bag forces
that could result in serious injury or death to the child, or the child may be slammed
into an adult, causing injury to both child and adult.
Never use a rear-facing child-restraint system in the front seat with an air bag that
could deploy:
Rear-facing child-restraint systems on the front seat are particularly dangerous even
though you may feel assured that a front passenger air bag will not deploy based on
the fact that the front passenger air bag deactivation indicator light illuminates.
The child-restraint system can be hit by a deploying air bag and moved violently
backward resulting in serious injury or death to the child.

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 equipped with LATCH lower anchors for attachment of specially
designed LATCH child-restraint systems in the rear seat. When using these anchors to
secure a child-restraint system, refer to“LATCH Child-Restraint Systems”(page 2-36).
