For details, refer to Front Passenger Air
Bag Deactivation Switch (page 2-51).

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 expert repairer (we
recommend an Authorised Mazda
Repairer).
WARNING
Wear seat belts only as recommended
in this owner's manual:
Incorrect positioning of the 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 Belt"
(page 2-22).
Have your seat belts changed
immediately if the pretensioner or
load limiter has been expended:
Always have an expert repairer (we
recommend an Authorised Mazda
Repairer) immediately inspect the seat
belt pretensioners and air bags after
any collision. Like the air bags, the seat
belt pretensioners and load limiters
will only function once and must be
replaced after any collision that caused
them to deploy. If the seat belt
pretensioners and load limiters are not
replaced, the risk of injury in a collision
will increase.
Do not modify the components or
wiring, or use electronic testing
devices on the pretensioner system:
Modifying the components or wiring of
the pretensioner system, including the
use of electronic testing devices is
dangerous. You could accidentally
activate it or make it inoperable which
would prevent it from activating in an
accident. The occupants or repairers
could be seriously injured.
Properly dispose of the pretensioner
system:
Improper disposal of the pretensioner
system or a vehicle with
non-deactivated pretensioners is
dangerous. Unless all safety
procedures are followed, injury could
result. Have an expert repairer (we
recommend an Authorised Mazda
Repairer) safely dispose of the
pretensioner system or scrap a
pretensioner system equipped vehicle.
Essential Safety Equipment
Seat Belt Systems

Never install any front-end equipment
to your vehicle:
Installation of front-end equipment,
such as frontal protection bar
(kangaroo bar, bull bar, push bar, or
other similar devices), snowplow, or
winches, is dangerous. The air bag
crash sensor system could be affected.
This could cause air bags to inflate
unexpectedly, or it could prevent the
air bags from inflating during an
accident. Front occupants could be
seriously injured.
Do not modify the suspension:
Modifying the vehicle suspension is
dangerous. If the vehicle's height or
the suspension is modified, the vehicle
will be unable to accurately detect a
collision or roll-over accident resulting
in incorrect or unexpected air bag
deployment and the possibility of
serious injuries.
Do not modify a front door or leave
any damage unrepaired. Always have
an expert repairer (we recommend an
Authorised Mazda Repairer) inspect a
damaged front door:
Modifying a front door or leaving any
damage unrepaired is dangerous. Each
front door has a side crash sensor as a
component of the supplementary
restraint system. If holes are drilled in a
front door, a door speaker is left
removed, or a damaged door is left
unrepaired, the sensor could be
adversely
affected causing it to not
detect the pressure of an impact
correctly during a side collision. If a
sensor does not detect a side impact
correctly, the side and curtain air bags
and the seat belt pretensioners may
not operate normally which could
result in serious injury to occupants.Do not modify the supplementary
restraint system:
Modifying the components or wiring of
the supplementary restraint system is
dangerous. You could accidentally
activate it or make it inoperable. Do
not make any modifications to the
supplementary restraint system. This
includes installing trim, badges, or
anything else over the air bag modules.
It also includes installing extra
electrical equipment on or near system
components or wiring. An expert
repairer (we recommend an
Authorised Mazda Repairer) can
provide the special care needed in the
removal and installation of front seats.
It is important to protect the air bag
wiring and connections to assure that
the bags do not accidentally deploy,
and that the driver seat slide position
sensor is not damaged and the seats
retain an undamaged air bag
connection.
Do not place luggage or other objects
under the front seats:
Placing luggage or other objects under
the front seats is dangerous. The
components essential to the
supplementary restraint system could
be damaged, and in the event of a side
collision, the appropriate air bags may
not deploy, which could result in death
or serious injury. To prevent damage to
the components essential to the
supplementary restraint system, do not
place luggage or other objects under
the front seats.

WARNING
Heed the following cautions to
prevent burns and electrical shock:
¾Never remove and disassemble the
brackets and connectors securing the
terminal part, wiring harness, and
the M Hybrid battery.
¾Never touch the M Hybrid battery
because it becomes extremely hot
under direct sunlight or after driving.
¾Because the M Hybrid battery is
especially dangerous when wet,
never touch it.
NOTE
The M Hybrid battery has a certain
battery life. Battery life
differs
depending on how the vehicle is used
and the driving conditions.

WARNING
Never touch the areas where high
current is flowing:
Never touch a M Hybrid related part.
Otherwise, it could lead to an
electrical shock or burns causing
serious injury.
Never touch electrical wiring that may
be protruding into or outside of the
cabin:
Otherwise, it could lead to an
electrical shock or burns causing
serious injury.
Never touch any area where
electrolyte is visible or electrolyte is
leaking from the area:
If any electrolyte from the M Hybrid
battery gets in the eyes or on the skin,
it could cause loss of vision or skin
reactions. In the unlikely event that
electrolyte comes into contact with the
eyes or skin, flush with large quantities
of water immediately and seek
immediate medical attention.
Do not come near the vehicle if
electrolyte is leaking from the M
Hybrid battery:
Even if the M Hybrid battery is
damaged, large quantities of
electrolyte will not flow out due to the
internal structure of the battery,
however, in the unlikely event that it
does, it will produce steam. The steam
contains properties that can irritate the
eyes and skin, and could cause acute
poisoning if absorbed.
Never approach objects that are on
fire or extremely hot:
Electrolyte in the M Hybrid battery may
cause a fire.
If the vehicle catches fire, extinguish
the fire using an ABC fire
extinguisher:
Only extinguish a fire with water when
large amounts of water is available
such as from a fire hydrant.

order of the removal procedure.
▼Replacing Interior Light Bulbs
LED type
xFront overhead lights/Front map
lights
xRear overhead lightxVanity mirror lights*
xLuggage compartment light
The LED bulb cannot be replaced as a
single unit because it is an integrated
unit.
The LED bulb has to be replaced with
the unit. We recommend an expert
repairer (we recommend an
Authorised Mazda Repairer) if the
replacement is necessary.
Fuses
▼Fuses
Your vehicle's electrical system is
protected by fuses.

If any lights, accessories, or controls do
not work, inspect the appropriate
circuit protector. If a fuse has blown,
the inside element will be melted.

If the same fuse blows again, avoid
using that system and consult an expert
repairer (we recommend an
Authorised Mazda Repairer) as soon as
possible.
▼Fuse Replacement
Replacing the fuses on the vehicle's
left side
If the electrical system does not work,
first inspect the fuses on the vehicle's
left side.

1. Make sure the ignition is switched
off, and other switches are off.
2. Open the fuse panel cover.
3. Pull the fuse straight out with the
fuse puller provided on the fuse
