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 no t 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 transporting cargo, do not allow the
cargo to exceed the height of the
seatbacks.
Transporting cargo stacked higher than
the seatbacks is dangerous as visibility to
the rear and sides of the vehicle is reduced
which could interfere with driving
operations and lead to an accident.
Lowering the seatbacks
CAUTION
 When folding the seatback forward,
always support the seatback with your
hand. If it is not supported by a hand,
fingers or the hand pressing the push
knob could be injured.
 Check the position of a front seat before
folding a rear seatback.
Depending on the position of a front
seat, it may not be possible to fold a rear
seatback all the way down because it
may hit the seatback of the front seat
which could scratch or damage the front
seat or its pocket. Remove the head
restraint on the rear outboard seat if
necessary.
 (Vehicles with rear armrest)
Before folding a rear seatback, make sure
that the armrest is stored. If a seatback is
lowered without storing the armrest, it
could deform, damage, or scratch the
armrest.
1. Lower the head restraint all the way down.
Refer to Head Restraints on page
2-17.

To return the seatback to its upright
position:
WARNING
When returning a seatback to its upright
position, make sure the 3-point seat belt is
not caught in the seatback and the 3-point
seat belt is not twisted.
If the seat belt is used while it is twisted and
caught in the seatback, the seat belt
cannot function at its full capacity, which
could cause serious injury or death.
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.

▼Removal/Installation
To remove the head restraint, pull it up
while pressing the stop-catch.
To install the head restraint, insert the legs
into the holes while pressing the
stop-catch.
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.
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
effectiveness of the head restraint
during a collision will be compromised
which could cause injury.

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.

(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 re ar 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.

(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 lo cks allow the belts to remain comfortable on
users, but they will lock in position during a collision.
WARNING
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.
