Push knob
To return the seatback to its upright
position:
WARNING
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.
When returning a seatback to its upright
position, make sure that it is firmly locked
and the red indication is not visible.
If the red indication is visible behind the
push knob, it means the seatback is not
locked. If the vehicle is driven without the
seatback locked, it could fold down
suddenly and cause an accident.

1. Make sure that the seat belt passes
through the seat belt guide correctly
and it is not twisted, then raise the
seatback while preventing the seat belt
from being caught in the seatback.

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.
WARNING
Always drive with the head restraints
installed when seats are being used and
make sure they are properly adjusted. In
addition, always raise the head restraints
on all rear seats when they are being used:
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.
▼ Height Adjustment
Adjust the head
restraint so that the center
is even with the top of the passenger's
ears.

To raise a head restraint, pull it up to the
desired position.
To lower the head restraint, press the
stop-catch release, then push the head
restraint down.

Seat Warmer*
The front seats are electrically heated. The
ignition must be switched ON.
Press the seat warmer switch while the
ignition is switched ON to operate the seat
warmer. The indicator lights turn on to
indicate that the seat warmer is operating.
The mode changes as follows each time
the seat warmer switch is pressed.
OFF
High Mid
Low
WARNING
Be careful when using the seat warmer:
The heat from the seat warmer may be too
hot for some people, as indicated as
follows, and could cause a
low-temperature burn.
 Infants, small children, elderly people,
and physically challenged people
 People with delicate skin
 People who are excessively fatigued
 People who are intoxicated
 People who have taken sleep-inducing
medicine such as sleeping pills or cold
medicine
Do not use the seat warmer with anything
having high moisture-retention ability such
as a blanket or cushion on the seat:
The seat may be heated excessively and
cause a low-temperature burn.
Do not use the seat warmer even when
taking a short nap in the vehicle:
The seat may be heated excessively and
cause a low-temperature burn.
Do not place heavy objects with sharp
projections on the seat, or insert needles or
pins into it:
This could cause the seat to become
excessively heated and result in injury from
a minor burn.
CAUTION
Do not use organic solvents to clean the
seat. It may damage the seat surface and
the heater.
NOTE
Use the seat warmer when the engine is
running. Leaving the seat warmer on for
long periods with the engine not running
could cause the battery power to be
depleted.
If the ignition is switched off while the
seat warmer is operating (High, Mid or
Low) and then switched ON again, the
seat warmer will automatically operate
at the temperature set before switching
off the ignition.
The temperature of the seat warmer
cannot be adjusted beyond High, Mid
and Low because the seat warmer is
controlled by a thermostat.

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/shoulder belts out of the way when
not in use.
The driver's seat belt has no provisions 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 front passenger's seat and all re ar lap/shoulder belt retractors operate in two
modes: emergency locking mode, and for child-restraint systems, automatic locking mode.
While we recommend you put all children in the rear seats, if you must use the front
passenger seat for a child, slide the front 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 retractors with inertia locks that keep
them out of the way when not in use. The lo cks allow the belts to remain comfortable on
users, but they will lock in position during a collision.
WARNING
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.

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 front 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 Taking Action on page 7-33.
Refer to Air Bag/Front Seat Belt
Pretensioner System Warning Beep on
page 7-42.
(With Front Passenger Occupant
Classification System)
In addition, the preten sioner system for the
front passenger, like the front and side
passenger air bag, is designed to only
deploy when the front passenger occupant
classification sensor detects a passenger
sitting on the front passenger's seat.
For details, refer to the front passenger
occupant classification sensor (page
2-66).

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.
WA R N I N G
Wear seat belts only as recommended in
this owner's manual:
Incorrect positioning of the driver and front
passenger 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 belts" (page 2-24).
