Supplemental Restraint
System (SRS) Precautions
▼ Supplemental Restraint System
(SRS) Precautions
The front and side supplemental
restraint systems (SRS) include
different
types of air bags. Please verify the
different types of air bags which are
equipped on your vehicle by locating
the “SRS AIRBAG” location indicators.
These indicators are visible in the area
where the air bags are installed.
The air bags are installed in the
following locations:

The steering wheel hub (driver air
bag)
The front passenger dashboard (front
passenger air bag)
Under the instrument panel (driver
and front passenger* knee air bags)The outboard sides of the front
seatbacks (side air bags)
The front and rear window pillars,
and the roof edge along both sides
(curtain air bags)

Vehicles with the Front Passenger
Occupant Classification System have a
sensor which detects an impending
roll-over accident.

The air bag supplemental restraint
systems are designed to provide
supplemental protection in certain
situations so seat belts are always
important in the following ways:

Without seat belt usage, the air bags
cannot provide adequate protection
during an accident. Seat belt usage is
necessary to:
Keep the occupant from being
thrown into an inflating air bag.
Reduce the possibility of injuries
during an accident that is not
designed for air ba g inflation, such as
rear impact.
Reduce the possibility of injuries in
frontal, near frontal or side collisions
or roll-over accidents that are not
severe enough to activate the air
bags.
Reduce the possibility of being
thrown from your vehicle.
Reduce the possibility of injuries to
lower body and legs during an
accident because the air bags
provide no protection to these parts
of the body.
Hold the driver in a position which
allows better control of the vehicle.

If your vehicle is also equipped with a
front passenger occupant
classification system, refer to the Front
Pa s s e n g e r O cc u p a n t Classification
System (page 2-64) for details.
If your vehicle is equipped with a front
passenger occupant classification
system, the front passenger air bag
deactivation indicator light illuminates
for a specified time after the ignition is
switched ON.

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.
To prevent false detection by the air
bag sensor system, heed the
following:
 Do not use tires or wheels other than
those specified for your Mazda:
Use of any tire or wheel other than
those specified for your Mazda (page
9-7) is dangerous. Use of such
wheels will prevent the vehicle's
accident detections system from
accurately detecting a collision or
roll-over accident resulting in
incorrect or unexpected air bag
deployment and the possibility of
serious injuries.
 Do not overload your vehicle:Overloading your vehicle is
dangerous as it could prevent the air
bag crash sensor system from
accurately detecting a collision or
roll-over accident resulting in
incorrect or unexpected air bag
deployment and the possibility of
serious injuries. The gross axle
weight rating (GAWR) and the gross
vehicle weight rating (GVWR) for
your vehicle are on the Motor
Vehicle Safety Standard Label on the
driver's door frame. Do not exceed
these ratings.
 Do not drive the vehicle off-road:
Driving your Mazda off-road is
dangerous because the vehicle has
not been designed to do so. Driving
the vehicle off-road could prevent
the air bag crash sensor system from
accurately detecting 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 Authorized Mazda Dealer 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 supplemental
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 supplemental
restraint system:
Modifying the components or wiring of
the supplemental restraint system is
dangerous. You could accidentally
activate it or make it inoperable. Do
not make any modifications to the
supplemental 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 Authorized
Mazda Dealer 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 front passenger occupant
classification system 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
supplemental 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
supplemental restraint system, do not
place luggage or other objects under
the front seats.
Do not operate a vehicle with
damaged air bag/seat belt
pretensioner system components:Expended or damaged air bag/seat
belt pretensioner system components
must be replaced after any collision
which caused them to deploy or
damage them. Only a trained
Authorized Mazda Dealer can fully
evaluate these systems to see that they
will work in any subsequent accident.
Driving with an expended or damaged
air bag or pretensioner unit will not
afford you the necessary protection in
the event of any subsequent accident
which could result in serious injury or
death.
Do not remove interior air bag parts:
Removing any components such as the
front seats, front dashboard, the
steering wheel or parts on the front
and rear window pillars and along the
roof edge, containing air bag parts or
sensors is dangerous. These parts
contain essential air bag components.
The air bag could accidentally activate
and cause serious injuries. Always have
an Authorized Mazda Dealer remove
these parts.
Properly dispose of the air bag
system:
Improper disposal of an air bag or a
vehicle with live air bags in it can be
extremely dangerous. Unless all safety
procedures are followed, injury could
result. Have an Authorized Mazda
Dealer safely dispose of the air bag
system or scrap an air bag equipped
vehicle.

How the SRS Air BagsWork
▼How the SRS Air Bags Work
Your Mazda is equipped with the
following types of SRS air bags. SRS air
bags are designed to work together
with the seat belts to help to reduce
injuries during an accident.
The SRS air bags are designed to
provide further protection for
passengers in addition to the seat belt
functions. Be sure to wear seat belts
properly.
▼Front Seat Belt Pretensioners
The front seat belt pretensioners are
designed to deploy in moderate or
severe frontal, near frontal collisions.
In addition, the pretensioners operate
when a side collision or a roll-over
accident is detected. The pretensioners
operate
differently depending on what
types of air bags are equipped. For
more details about seat belt
pretensioner operation, refer to the
SRS Air Bag Deployment Criteria (page
2-60).
▼ Driver Air Bag
The driver's air bag is mounted in the
steering wheel.
When air bag crash sensors detect a
frontal impact of greater than
moderate force, the driver's air bag
inflates quickly helping to reduce injury
mainly to the driver's head or chest
caused by directly hitting the steering
wheel.
For more details about air bag
deployment, refer to "SRS Air Bag
Deployment Criteria" (page 2-60).
(With Front Passenger Occupant
Classification System)
The driver's dual-stage air bag controls
air bag inflation in two energy stages.
During an impact of moderate severity,
the driver's air bag deploys with lesser
energy, whereas during more severe
impacts, it deploys with more energy.
▼Front Passenger Air Bag
The front passenger air bag is mounted
in the front passenger dashboard.
The inflation mechanism for the front
passenger air bag is the same as the
driver's air bag.
For more details about air bag
deployment, refer to "SRS Air Bag
Deployment Criteria" (page 2-60).
(With Front Passenger Occupant
Classification System)
In addition, the front passenger air bag
is designed to only deploy in
accordance with the total seated
weight on the front passenger seat. For
details, refer to the front passenger

occupant classification system (page
2-64).
▼Driver and Front Passenger Knee
Air Bags*
The knee air bags are equipped under
the instrument panel.
If the air bag crash sensors receive a
frontal impact of greater than
moderate force, the knee air bags
deploy immediately to reduce impact
to the driver and front passenger's
legs.
For more details about air bag
deployment, refer to "SRS Air Bag
Deployment Criteria" (page 2-60).
▼
Side Air Bags
The side air bags are mounted in the
outboard sides of the front seatbacks.
When the air bag crash sensors detect
a side impact of greater than moderate
force, the system inflates the side air
bag only on the side in which the
vehicle was hit. The side air bag inflates
quickly to reduce injury to the driver or
front passenger's chest caused by
directly hitting interior parts such as a
door or window.
For more details about air bag
deployment, refer to "SRS Air Bag
Deployment Criteria" (page 2-60).
(With Front Passenger Occupant
Classification System)
In addition, the front passenger side air
bag is designed to only deploy in
accordance with the total seated
weight on the front passenger seat. For
details, refer to
the front passenger
occupant classification system (page
2-64).

▼ Curtain Air Bags
The curtain air bags are mounted in the
front and rear window pillars, and the
roof edge along both sides.
When the air bag crash sensors detect
a side impact of greater than moderate
force, the curtain air bag inflates
quickly and helps to reduce injury
mainly to the driver and front and rear
outboard passengers' heads caused by
directly hitting interior parts such as a
door or window.
For more details about air bag
deployment, refer to "SRS Air Bag
Deployment Criteria" (page 2-60).
In a side impact:
Greater than moderate impact to one
side of the vehicle will cause the

▼ Driver and Front Passenger
Occupant Classification System
First, please read "Supplemental
Restraint System (SRS) Precautions"
(page 2-49) carefully.
▼Driver Seat Slide Position Sensor
Your vehicle is equipped with a driver
seat slide position
sensor as a part of
the supplemental restraint system. The
sensor is located under the driver seat.
The sensor determines whether the
driver seat is fore or aft of a reference
position and sends the seat position to
the diagnostic module (SAS unit).
The SAS unit is designed to control the
deployment of the driver air bag
depending on how close the driver
seat is to the steering wheel.
The air bag/front seat belt
pretensioner system warning light
flashes if the sensor has a possible
malfunction (page 2-59).
▼ Front Passenger Seat Weight
Sensors
Your vehicle is equipped with a front
passenger seat weight sensors as a part
of the supplemental restraint system.
These sensors are located under both
of the front passenger seat rails. These
sensors determine the total seated
weight on the front passenger seat and
monitor the seat belt buckle for the
front passenger seat. The SAS unit is
designed to prevent the front
passenger front and side air bags and
knee air bags, and seat belt
pretensioner system from deploying if
the front passenger air bag
deactivation indicator light illuminates.
To reduce the chance of injuries
caused by deployment of the front
passenger air bag, the system
deactivates the front passenger front
and side air bags and knee air bags,
and also the seat belt pretensioner
system when the front passenger air
bag deactivation indicator light
illuminates. Refer to the following
table for the front passenger air bag
deactivation indicator light
illumination conditions.

This system shuts off the front
passenger front and side air bags and
knee air bags, and seat belt
pretensioner system, so make sure the
front passenger air bag deactivation
indicator light illuminates 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
knee air bags, and seat belt
pretensioner system will not deploy.
