Seat Belt Systems
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
suf¿ cient occupant movement.
Even if the pretensioners have not ¿ red,
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
2-18 ).

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.

WARNING
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
SRS Air Bags
WARNING
Do not touch the components of the supplementary restraint system after the air bags
have inÀ ated:
Touching the components of the supplementary restraint system after the air bags have
inÀ ated is dangerous. Immediately after inÀ ation, they are very hot. You could get
burned.

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 inÀ ate
unexpectedly, or it could prevent the air bags from inÀ ating 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 modi¿ ed, the vehicle will be unable to accurately detect a collision 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 front seat belt pretensioner 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
modi¿ cations 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.

CAUTION

 Do not mount any transceiver, microphones, speakers, or any other item in the
deployment path of the air bag system.
  Do not fasten aerial lead to original vehicle wiring, fuel pipes or brake pipes. Avoid
running the aerial lead parallel with the wire harness to the best extent possible.
  Keep the aerial and power leads at least 100 mm (3.9 in) from any electronic modules
and the air bags.
  Avoid using the cigar lighter or accessory socket as a power source for the RF-
transmitting equipment.
