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).

WARNING
Always attach the tether strap to the
correct tether anchor position:
Attaching the tether strap to the incorrect
tether anchor position is dangerous. In a
collision, the tether strap could come off
and loosen the child-restraint system. If the
child-restraint system moves it could result
in death or injury to the child.
Always remove the head restraint and
install child-restraint system:
Installing a child-restraint system without
removing the head restraint is dangerous.
The child-restraint system cannot be
installed correctly which may result in
death or injury to the child in a collision.
Tether strapForward
Tether strap
Forward
Always install the head restraint and adjust
it to the appropriate position after
removing the child-restraint system:
Driving with the head restraint removed is
dangerous as impact to the occupant's
head cannot be prevented during
emergency braking or in a collision, which
could result in a serious accident, injury or
death.
Refer to Head Restraints on page 2-17.
▼ Using Automatic Locking Mode
(Except Mexico)
Follow these instructions when using a
child-restraint system, unless you are
attaching a LATCH-equipped
child-restraint system
to the rear LATCH
lower anchors. Refer to “Using LATCH
Lower Anchor” (page 2-47).
NOTE
Follow the child-restraint system
manufacturer's instru ctions carefully. If
you are not sure whether you have a
LATCH system or tether, check in the
child-restraint system manufacturer's
instructions and follow them accordingly.
Depending on the type of child-restraint
system, it may use LATCH system instead
of seat belts or if the belt goes across the
child's chest, may recommend against
using automatic locking mode.
1. Make sure the seatback is securely latched by pushing it back until it is
fully locked.
2. Remove the head restraint. However,
when installing a backless booster seat,
always install the vehicle head restraint
to the seat where the backless booster
seat is installed.
Refer to Head Restraints on page 2-17.

Front Passenger Occupant Classification System*
First, please read "Supplemental Restraint System (SRS) Precautions" (page 2-51) carefully.
▼Front Passenger Occupant
Classification Sensor
Your vehicle is equipped with a front passenger occupant classification sensor as a part of
the supplemental restraint system. This sensor is equipped in the front passenger's seat
cushion. This sensor measures the electrostatic capacity of the front passenger's seat. The
SAS unit is designed to prevent the front pass enger front and side air bags and seat belt
pretensioner system from deploying if the front passenger air bag deactivation indicator
light turns on.
To reduce the chance of injuries caused by de ployment of the front passenger air bag, the
system deactivates the front passenger front and side air bags and also the seat belt
pretensioner system when the front passenger air bag deactivation indicator light turns on.
Refer to the following table for the front pa ssenger air bag deactivation indicator light
illumination conditions.

This system shuts off the front passenger front and side air bags and seat belt pretensioner
system, so make sure the front passenger air bag deactivation indicator light turns on
according to the following table.

The air bag/front seat belt pretensioner system warning light flashes and the front passenger
air bag deactivation indicator light illuminates if the sensors have a possible malfunction. If
this happens, the front passenger front and side air bags and seat belt pretensioner system
will not deploy.
Front passenger air bag de activation indicator light
This indicator light turns on to remind you that the front passenger front and side air bags
and seat belt pretensioner wi ll not deploy during a collision.
If the front passenger occupant classification sensor is normal, the indicator light turns on
when the ignition is switch ed ON. The light turns off af ter a few seconds. Then, the
indicator light turns on or is off under the following conditions:
