Seat Precautions
▼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
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. Cons ult 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.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
vehicle 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.
Always leave your car locked and keep the
car keys safely away from children (4–
Door):
Leaving your car unlocked or the keys in
reach of children is dangerous. Children
who find their way into the trunk through
an unlocked rear seatback or 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, and as an added
measure, keep the rear seatbacks locked,
whether you have children in your home or
not.

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.
 When inserting your hand under the seat
to clean the cabin or pick up something
you dropped under the seat, be careful
not to hurt yourself. If you contact the
moving parts and surrounding parts
around the seat rail, seat frame, and the
bottom of the seat, it could result in
injury.
NOTE
When returning a rear seat to its
original position, place the seat belt in
its normal position. Verify that the seat
belt pulls out and retracts.
(Power Seat)
The seat-bottom power adjustment is
operated by motors. Avoid extended
operation because excessive use can
damage the motors.
To prevent the battery from running
down, avoid using the power
adjustment when the engine is
stopped. The adjuster uses a large
amount of electrical power.
Do not use the switch to make more
than one adjustment at a time.
