Seat Precautions
▼Seat Precautions
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.
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 allow 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 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.

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 injuries.
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, which 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.
Additionally, if the air bags deploy, the
cargo may scatter which could result in
serious injury or death.
Never allow a passenger to sit or
stand on the folded seatback while
the vehicle is moving:
Driving with a passe nger 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 vehicle 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 your 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.
 (Manual Seat)
When moving the seats forward and
rearward or returning a rear-reclined
seatback to its upright position,
make sure you hold onto the
seatback with your hand while
operating. If the seatback is not held,
the seat will move suddenly and
could cause injury.

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.
Have your seat belts changed
immediately if the pretensioner or
load limiter has been expended:
Always have an Authorized Mazda
Dealer immediately inspect the seat
belt pretensioners and air bags after
any collision. Like the air bags, 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 pretensioner 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 positioned 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 abdominal area,
causing serious injury. Wear the lap
portion of the belt snugly and as low as
possible.

In a rollover crash, an unbelted person
is significantly more likely to die than a
person wearing a seat belt.

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
6-49).

Front Seat Belt
Pretensioner and Load Limiting Systems
▼Front Seat Belt Pretensioner and
Load Limiting Systems
For optimum protection, the driver and
front passenger seat belts are
equipped with pretensioner and load
limiting systems. For both these
systems to work properly you must
wear the seat belt properly.

Pretensioners:
When a collision is detected, the
pretensioners deploy simultaneously
with the air bags.
For vehicles with the front passenger
occupant classification system, the
pretensioners deploy simultaneously
with the air bags when a roll-over is
also detected.
For deployment details, refer to the
SRS Air Bag Deployment Criteria (page
2-63).

The seat belt retractors remove slack
quickly as the air bags are expanding.
Any time the air bags and seat belt
pretensioners have
fired they must be
replaced.
A system malfunction or operation
conditions are indicated by a warning.
Refer to Air Bag/Front Seat Belt
Pretensioner System Warning
Indication/Warning Light on page
7-27.
(With Front Passenger Occupant
Classification System)
In addition, the pretensioner system
for the front passenger, like the front
and side passenger air bag , is designed
to only deploy in accordance with the
total seated weight on the front
passenger seat.
For details, refer to the front passenger
seat weight sensors (page 2-67).

Load limiter:
The load limiting system releases belt
webbing in a controlled manner to
reduce belt force on the occupant's
chest. While the most severe load on a
seat belt occurs in frontal collisions,
the load limiter has an automatic
mechanical function and can activate
in any accident mode with sufficient
occupant movement.
Even if the pretensioners have not
fired, the load limiting function must
be checked by an Authorized Mazda
Dealer.
WARNING
Wear seat belts only as recommended
in this owner's manual:
Incorrect positioning of the seat belts is
dangerous. Without proper
positioning, the pretensioner and load
limiting systems cannot provide
adequate protection in an accident
and this could result in serious injury.
For more details about wearing seat
belts, refer to "Fastening the Seat Belt"
(page 2-24).

Have your seat belts changed
immediately if the pretensioner or
load limiter has been expended:
Always have an Authorized Mazda
Dealer immediately inspect the seat
belt pretensioners and air bags after
any collision. Like the air bags, 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 pretensioner 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.
Do not modify the components or
wiring, or use electronic testing
devices on the pretensioner system:
Modifying the components or wiring of
the pretensioner system, including the
use of electronic testing devices is
dangerous. You could accidentally
activate it or make it inoperable which
would prevent it from activating in an
accident. The occupants or repairers
could be seriously injured.
Properly dispose of the pretensioner
system:
Improper disposal of the pretensioner
system or a vehicle with
non-deactivated pretensioners is
dangerous. Unless all safety
procedures are followed, injury could
result. Have an Authorized Mazda
Dealer safely dispose of the
pretensioner system or scrap a
pretensioner system equipped vehicle.NOTE
The pretensioner system may not
operate depending on the type of
the collision. For details, refer to the
SRS Air Bag Deployment Criteria
(page 2-63).
Some smoke (non-toxic gas) will be
released when the air bags and
pretensioners deploy. This does not
indicate a fire. This gas normally has
no effect on occupants, however,
those with sensitive skin may
experience light skin irritation. If
residue from the deployment of the
air bags or the pretensioner system
gets on the skin or in the eyes, wash
it off as soon as possible.

Do not leave a seat belt extender
connected to the buckle:
Leaving a seat belt extender connected
to the buckle without using the seat
belt is dangerous. When the seat belt
extender is connected to the driver's
seat belt buckle (or front passenger's
seat belt buckle), the SRS driver's (or
front passenger's) air bag system will
determine that the driver (or front
passenger) is wearing the seat belt
even if the driver (or front passenger) is
not wearing it. This condition could
cause the driver's (or front
passenger's) air bag to not activate
correctly and result in death or serious
injury in the event of collision. Always
wear the seat belt with the seat belt
extender.
Do not use the seat belt extender
when installing a child-restraint
system on the front or rear passenger
seat:
Using a seat belt extender to fasten a
child-restraint system on any seat is
dangerous. Always follow the
child-restraint system manufacturer's
installation instructions and never use
a seat belt extender.
NOTE
When not in use, remove the seat belt
extender and store it in the vehicle. If
the seat belt extender is left
connected, the seat belt extender
might get damaged as it will not retract
with the rest of the seat belt and can
easily fall out of the door when not in
use and be damaged. In addition, the
seat belt warning light will not
illuminate and function properly.

Child-RestraintPrecautions
▼ 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
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 Occupant
Classification System)
To reduce the chance of injuries
caused by deployment of the front
passenger air bag, the front passenger
seat weight sensors occupant
classification sensor works as a part of
the supplemental restraint system. This
system deactivates the front passenger
front and side air bags and knee air
bags, and also the front passenger seat
belt pretensioner system when the
front passenger air bag deactivation
indicator light illuminates.

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 knee 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
2-67).
