Seat Precautions
WA R N I N G
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.
Never allow children to adjust a seat:
Allowing children to adjust a seat is dangerous as it could result in serious injury if a child's
hands or feet become caught in the seat.
Do not drive with the seatback unlocked:
All of the seatbacks play an important role in your protection in a vehicle. Leaving the
seatback unlocked is dangerous as it can a llow passengers to be ejected or thrown around
and baggage to strike occupants in a sudden stop or collision, resulting in severe injury. After
adjusting the seatback at any time, even when there are no other passengers, rock the
seatback to make sure it is locked in place.
Adjust a seat only when the vehicle is stopped:
If the seat is adjusted while the vehicle is being driven, the seating posture may become
unstable and the seat could move unexpectedly resulting in injury.
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, such as se at cushions torn or damaged down to the
urethane, 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.

Do not drive with either front seats reclined:
Sitting in a reclined position while the vehicle is moving is dangerous because you do not get
the full protection from seat belts. During sudden braking or a collision, you can slide under
the lap belt and suffer serious internal injuri es. For maximum protection, sit well back and
upright.
Do not place an object such as a cushion between the seatback and your back:
Putting an object such as a cushion between the seatback and your back is dangerous
because you will be unable to maintain a safe driving posture and the seat belt cannot
function at its full capacity in a collision, wh ich could result in a serious accident, injury or
death.
Do not place objects under the seat:
The object could get stuck and cause the seat to not be fixed securely, and result in an
accident.
Do not stack cargo higher than the seatbacks:
Stacking luggage or other cargo higher than the seatbacks 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.
Never allow a passenger to sit or stand on the folded seatback while the vehicle is moving:
Driving with a passenger on the folded seatback is dangerous. Allowing a child to sit up on
the folded seatback while the vehicle is moving is particularly dangerous. In a sudden stop or
even a minor collision, a child not in a proper seat or child-restraint system and seat belt could
be thrown forward, back or even out of the vehi cle resulting in serious injuries or death. The
child in the baggage area could be thrown into other occupants and cause serious injury.
CAUTION
 When operating a seat, be careful not to put yo ur hands or fingers near the moving parts of
the seat or on the side trim to prevent injury.
 When moving the seats, make sure there is no cargo in the surrounding area. If the cargo
gets caught it could damage the cargo.

Rear Seat
▼ Split Folding the Seatbacks
By lowering the rear seatbacks the luggage
compartment space can be expanded.
WA R N I N G
Do not drive the vehicle with occupants on
folded down seatbacks or in the luggage
compartment.
Putting occupants in the luggage
compartment is dangerous because seat
belts cannot be fastened which could lead
to serious injury or death during sudden
braking or a collision.
Do not allow children to play inside the
vehicle with the seatbacks lowered.
Allowing children to play in the vehicle
with the seatbacks folded down is
dangerous. If a child enters the luggage
compartment and the seatbacks were
raised back up, the child may become
trapped in the luggage compartment
which could lead to an accident.
Tightly secure cargo in the luggage
compartment when it is transported with
the seatbacks folded down.
Driving without tightly securing cargo and
luggage is dangerous as it could move and
become an obstruction to driving during
emergency braking or a collision resulting
in an unexpected accident.

When returning a seatback to its upright
position, make sure that it is firmly locked
and the red indication is not visible.
If the red indication is visible behind the
push knob, it means the seatback is not
locked. If the vehicle is driven without the
seatback locked, it could fold down
suddenly and cause an accident.

2. Press the seatback rearward and lock it
in place. After returning the seatback
to its upright posi tion, make sure it is
securely locked.
▼ Armrest*
The rear armrest in the center of the rear
seatback can be used (no occupant in the
center seat) or placed upright.

WA R N I N G
Never position the shoulder portion of a
seat belt over the armrest:
Positioning the shoulder portion of a rear
seat belt over the armrest is dangerous as it
cannot provide adequate protection in a
collision and could result in serious injuries.
Never put your hands and fingers around
the moving parts of the seat and armrest:
Putting your hands and fingers around the
moving parts of the seat and armrest is
dangerous as they could get injured.
CAUTION

Be careful not to apply excessive force to
the armrest such as by sitting on it.
Otherwise, it could be deformed or
damaged.

WA R N I N G
Always drive with the head restraints
installed when seats are being used and
make sure they are properly installed:
Driving with the head restraints not
installed is dangerous. With no support
behind your head, your neck could be
seriously injured in a collision.
After installing a head restraint, try lifting it
to make sure that it does not pull out:
Driving with an unsecured head restraint is
dangerous as the effectiveness of the head
restraint will be compromised which could
cause it to unexpectedly detach from the
seat.

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 alwa ys wear seat belts.

(Except Mexico)
All of the seat belt retractors are designed to keep the lap/sh oulder belts out of the way when
not in use.
The driver's seat belt has no pr ovisions 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 s eat 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 y ou 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 sy stem is secured properly.

(Mexico)
All the seats have lap/shoulder belts. These belts have retract ors 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.
WA R N I N G
Always wear your seat belt and make sure all occupants are properly restrained:
Not wearing a seat belt is extremely dangerou s. 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 fu ll 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. Ne ver use one belt for more than one person at a
time and always operate the vehicle wi th each occupant properly restrained.

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 pro vincial laws for specific requirements regarding the safety
of children riding in your vehicle.

Whatever child-restraint system you consider, please pick the a ppropriate 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-re straint 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 th e 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 supplementa l 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 Occupa nt Classification System)
To reduce the chance of injuries caused by deployment of the front passenger air bag, the
front passenger occupant classification sensor works as a part of the supplemental restraint
system. This system deactivates the front passenger front and s ide air bags and also the front
passenger seat belt pretensioner system when the front passenge r air bag deactivation
indicator light illuminates.

When an infant or small child si ts on the front passenger seat, the system shuts off the front
passenger front and side air bags and seat belt pretensioner sy stem, so make sure the front
passenger air bag deactivation indicator light illuminates.

Even if the fron t 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, re fer to "Front passeng er occupant classifica tion sensor" (page 2-61).

WA R N I N G
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 ve hicle 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 ba g 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 viol ently backward resulting in serious injury or
death to the child.
