2021 MAZDA MODEL 3 HATCHBACK warning light

If your vehicle is also equipped with a
front passenger occupant
classification system, refer to the Front
Passenger Occupant Classi fication
System (page 2-70) for details.
If your vehicle is equipped with a front
passenger occupant classi fication
system, the front passenger air bag
deactivation indicator light illuminates
for a speci fied time after the ignition is
switched ON.


Small children must be protected by a
child-restraint system as stipulated by
law in every state and province. In
certain states and provinces, larger
children must use a child-restraint
system (page 2-32).

Carefully consider which child-restraint
system is necessary for your child and
follow the installation directions in this
Owner's Manual as well as the
child-restraint system manufacturer's
instructions.
WARNING
Seat belts must be worn in air bag
equipped vehicles:
Depending only on the air bags for
protection during an accident is
dangerous. Alone, air bags may not
prevent serious injuries. The
appropriate air bags can be expected
to in flate only in the first accident, such
as frontal, near frontal or side collisions
or roll-over accidents that are at least
moderate. Vehicle occupants should
always wear seat belts.

Children should not ride in the front
passenger seat:
Placing a child, 12 years or under, in
the front seat is dangerous. The child
could be hit by a deploying air bag and
be seriously injured or even killed. A
sleeping child is more likely to lean
against the door and be hit by the side
air bag in moderate collision to the
front-passenger side of the vehicle.
Whenever possible, always secure a
child 12 years and under on the rear
seats with an appropriate
child-restraint system for the child's
age and size.

▼ 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.

▼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 o
ff 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
fl ashes 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.
Front passenger air bag deactivation
indicator light
This indicator light illuminates to
remind you that the front passenger
front and side air bags and knee air
bags, and seat belt pretensioners will
not deploy during a collision.

being a child depending on the person's
physique.
The curtain air bag is ready for in flating
regardless of what the front passenger air bag
deactivation indicator light on/o ff condition
chart indicates.

If the front passenger air bag
deactivation indicator light does not
illuminate when the ignition is
switched ON and does not illuminate
as indicated in the front passenger air
bag deactivation indicator light on/o ff
condition chart, do not allow a child to
sit in the front passenger seat and
consult an Authorized Mazda Dealer
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:

seconds to alternate between turning
the front passenger front and side air
bags and knee air bags, and seat belt
pretensioner system on or o ff.
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.
