2018 MAZDA MODEL 3 HATCHBACK Owners Manual (in English)

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.

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 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.
 (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.
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.

When transporting cargo, do not allow the
cargo to exceed the height of the
seatback(s).

folding a rear seatback.
Depending on the position of a front seat, it
may not be possible to fold a rear seatback
