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 the driver's 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.
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 ba g components essential to the supplemental
restraint system. Such modifications could damage the supplemental restraint system and
result in serious injury. Consul t 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 seat 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.

Mazda3_8GE4-EA-17F_Edition1 2017-4-7 11:59:21

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 be lts. 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 betwee n 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.
Never give the car keys to children and do not allow them to play in the vehicle (4–Door):
Playing with the folding rear seats is dangerous. Once the seatbacks are back up, a child in the
trunk would not be able to get out the way they had entered. If you have small children, keep
the seatbacks locked.

Rear Seat
▼Split/One-piece Folding the
Seatback
By lowering the rear seatback(s) the
luggage compartment space can be
expanded.
WA R N I N G
Do not drive the vehicle with occupants on
folded down seatback(s) 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 seatback(s) lowered.
Allowing children to play in the vehicle with
the seatback(s) folded down is dangerous.
If a child enters the luggage compartment
and the seatback(s) 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 seatback(s) 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
seatback(s).
Transporting cargo stacked higher than the
seatback(s) 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 seatback(s)
CAUTION
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. Lower or remove the head restraint
on the rear outboard seat if necessary.
(4–Door)

WA R N I N G
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.

Head Restraints
Your vehicle is equipped with head
restraints on all outboard seats and the rear
center seat. The head restraints are
intended to help protect you and the
passengers from neck injury.
WA R N I N G
Always drive with the head restraints
installed when seats are being used and
make sure they are properly adjusted:
Driving with the head restraints adjusted
too low or removed is dangerous. With no
support behind your head, your neck could
be seriously injured in a collision.

desired position.
To lower the head restraint, press the
stop-catch release, then push the head
restraint down.

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/sh oulder belts out of the way when
not in use.
The driver's seat belt has no provisions for child-restraint sy stems 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 b elt retractors operate in two
modes: emergency locking mode, and for child-restraint systems, automatic locking mode.
While we recommend you put all chi ldren in the rear seats, if you must use the front
passenger seat for a child, slide the front passenger seat as f ar 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 th e 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 full 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. 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 be lt systems in use during an accident before
they are used again.
Have your seat belts changed immediately if the pretensioner or load limiter has been
expended:
Always have an Authorized Mazda Dealer imme diately inspect the seat belt pretensioners
and air bags after any collision. Like the air ba gs, the seat belt pretensioners and load limiters
will only function once and must be replaced after any collision that caused them to deploy. A
seat belt with an expended pret ensioner or load limiter is still better than wearing no seat belt
at all; however, if the seat belt pretensioners and load limiters are not replaced, the risk of
injury in a collision will increase.
Positioning the Shoulder Portion of the Seat Belt:
Improper positioning of the shoulder portion of the seat belt is dangerous. Always make sure
the shoulder portion of the seat belt is positi oned across your shoulder and near your neck,
but never under your arm, on your neck, or on your upper arm.
Positioning the Lap Portion of the Seat Belt:
The lap portion of the seat belt worn too high is dangerous. In a collision, this would
concentrate the impact force directly on the a bdominal area, causing serious injury. Wear the
lap portion of the belt snugly and as low as possible.
CAUTION
Belt retraction may become difficult if the belts and rings are soiled, so try to keep them clean.
For more details about cleaning the seat belts, refer to "Seat Belt Maintenance" (page 6-69).
