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
2-67).
▼ 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 2-67).
(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 mechan
ism 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 2-67).
(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
2-70).
▼ 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 2-67).

▼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 2-67).
(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
2-70).

▼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 2-67).
In a side impact:
Greater than moderate impact to one
side of the vehicle will cause the
curtain air bag on that side only to
inflate.

Only one side curtain air bag will
deploy on the side of the vehicle that
receives the force of an impact.

In a roll-over:
In response to a vehicle roll-over, both
curtain air bags inflate.

Both curtain air bags will deploy after
the roll-over accident is detected.

A system malfunction or operation
conditions are indicated by a warning.

Limitations to roll-over detection
(With Front Passenger Occupant
Classification System):
The following illustration is an example
of an accident that may not be
detected as a roll-over accident.
Therefore, the front seat belt
pretensioners and curtain air bags may
not deploy.

▼ Driver and Front Passenger
Occupant Classification System
First, please read "Supplemental
Restraint System (SRS) Precautions"
(page 2-55) 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 2-66).

A rear passenger steps on the front
passenger seat rails with their feet.
 Luggage or other items are placed on
the seatback or hung on the head
restraint.
 Heavy items are placed in the
seatback map pocket.
 The seat is washed.
 Liquids are spilled on the seat.
 The front passenger seat is moved
backward, pushing into luggage or
other items placed behind it.
 The front passenger seatback
contacts the rear seat.
 Luggage or other items are placed
between the front passenger seat
and driver seat.
 Any accessories which might increase
the total seated weight on the front
passenger seat are attached to the
front passenger seat.
CAUTION
To assure proper deployment of the
front air bag and to prevent damage
to the sensors in the front seat
bottoms:
 Do not place sharp objects on the
front seat bottoms or leave heavy
luggage on them.
 Do not spill any liquids on the
front seats or under the front seats.
 To allow the sensors to function
properly, always perform the
following:
 Adjust the front seats as far back as
possible and always sit upright
against the seatbacks with seat
belts worn properly.
If you place your child on the front
passenger seat, secure the
child-restraint system properly and
slide the front passenger seat as far
back as possible (page 2-47).
NOTE
The system requires about 10
seconds to alternate between turning
the front passenger front and side air
bags and knee air bags, and seat belt
pretensioner system on or off.
The front passenger air bag
deactivation indicator light may
illuminate repeatedly if luggage or
other items are put on the front
passenger seat, or if the temperature
of the vehicle's interior changes
suddenly.
The front passenger air bag
deactivation indicator light may
illuminate for 10 seconds if the total
seated weight on the front passenger
seat changes.
The air bag/front seat belt
pretensioner system warning light
might illuminate if the front
passenger seat receives a severe
impact.
If the front passenger air bag
deactivation indicator light does not
illuminate after installing a
child-restraint system on the front
passenger seat,
first, re-install your
child-restraint system according to
the procedure in this owner's
manual. Then, if the front passenger
air bag deactivation indicator light
still does not illuminate, install the
child-restraint system on the rear seat
and consult an Authorized Mazda
Dealer as soon as possible.
