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 seats:
Modifying or replacing the seats such as repl acing the upholstery or loosening any bolts is
dangerous. The 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 Author ized Mazda Dealer if there is any need to remove or reinstall
the seats.
Do not drive with damaged seats:
Driving with damaged 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
seats which contain essential air bag components. If there was a subsequent collision, an air
bag may not deploy which could lead to injuri es. Always have an Authorized Mazda Dealer
inspect the seats, seat belt pretensioners and air bags after a collision.

Do not drive with either 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.
Always leave your car locked and keep the car keys safely away from children:
Leaving your car unlocked or the keys in reach of children is dangerous. Children who find
their way into the trunk through an open trunk can become accidentally locked in the trunk.
This could result in death or brain damage from heat prostration, particularly in the summer.
Always lock the doors and the trunk.
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.
 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.

Seat Belt Precautions
Seat belts help to decrease the possibility of severe injury during accidents and sudden
stops. Mazda recommends that the driver and passengers always w ear 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 passenger's seat lap/shoulder belt retractor opera tes in two modes: emergency
locking mode, and for child-res traint systems, automatic lockin g mode. If you must use the
passenger seat for a ch ild, slide the 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 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.

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.
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.
Always make sure the passenger air bag deactivation indicator light is illuminated when
using a child-restraint system:
Seating a child in a child-restraint system that is installed on the passenger seat with the
passenger air bag deactivation indicator light not illuminated is extremely dangerous. In an
accident, an air bag could inflate and cause serious injuries or even death to the child seated
in the child-restraint system. Always make sure the passenger air bag deactivation indicator
light is illuminated.
Refer to Passenger Occupant Classification System on page 2-40.
(Except Mexico)
Vehicles with a passenger air bag have the fo llowing warning label. The warning label is
displayed in compliance with regulations.

An additional electrical device , such as a seat warmer is installed to the surface of the
passenger seat.
Do not allow a child or anyone to lean over or against the side window of a vehicle with side
air bags:
It is dangerous to allow anyone to lean over or against the side window, the area of the
passenger seat from which the side air bags depl oy, even if a child-restraint system is used.
The impact of inflation from a side air bag co uld cause serious injury or death to an out of
position child. Furthermore, leaning over or ag ainst the door could block the side air bags and
eliminate the advantages of su pplemental protection. Because the side air bag deploys from
the outboard shoulder of the seat, do not allow the child to lean over or against the side
window, even if the child is seated in a child-restraint system.
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.
Always use a child-restraint system designed for use without a tether or the LATCH lower
anchor:
Using a child-restraint system that requires a tether or the LATCH lower anchor is dangerous.
Your Mazda does not have a child-restraint tether or the LATCH lower anchor. The
child-restraint system cannot be properly secured . In a collision, it could move and injure
other occupants as well as result in serious injuries or death to the child.
CAUTION
A seat belt or child-restraint system can beco me 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.
