Seat MAZDA MODEL CX-30 2021 Repair Manual

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.
NOTE
If it becomes necessary to have the
components or wiring system for the
supplementary restraint system
modified to accommodate a person
with certain medical conditions in
accordance with a certified
physician, contact an Authorized
Mazda Dealer, refer to “Customer
Assistance (U.S.A.)” (page 8-2).
When an air bag deploys, a loud
inflation noise can be heard and
some smoke will be released.
Neither is likely to cause injury,
however, the texture of the air bags
may cause light skin injuries on body
parts not covered with clothing
through friction.
Should you sell your Mazda, we urge
you to tell the new owner of its air
bag systems and that familiarization
with all instructions about them,
from the Owner's Manual, is
important.
This highly-visible label is displayed
which warns against the use of a
rear-facing child-restraint system on
the front passenger seat.

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
2-63).
▼ 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 2-63).
(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 2-63).

(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
2-66).
▼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 2-63).
▼
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 2-63).
(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
2-66).

▼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 2-63).
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.
(With Front Passenger Occupant
Classification System)
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.

▼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.

as soon as possible. The system may
not work properly in an accident.
WARNING
Do not decrease the total seated
weight on the front passenger seat:
When an adult or large child sits on the
front passenger seat, decreasing the
total seated weight on the front
passenger seat required for air bag
deployment is dangerous. The front
passenger seat weight sensors will
detect the reduced total seated weight
condition and the front passenger front
and side air bags and knee air bags,
and the seat belt pretensioner system
will not deploy during an accident. The
front passenger will not have the
supplementary protection of the air
bag, which could result in serious
injury. Decreasing the total seated
weight on the front passenger seat
could result in an air bag not deploying
under the following conditions, for
example:
