2022 MAZDA MODEL 3 SEDAN air condition

▼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.
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.

If the front passenger weight sensors
are normal, the indicator light
illuminates when the ignition is
switched ON. The light turns off after a
few seconds. Then, the indicator light
illuminates or is off under the following

physique.
The curtain air bag is ready for inflating
regardless of what the front passenger air bag
deactivation indicator light on/off 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/off
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:

A front passenger is seated as shown
in the following figure:
A rear passenger pushes up on the
front passenger seat with their feet.
Luggage or other items placed under
the front passenger seat or between
the front passenger seat and driver
seat that push up the front passenger
seat bottom.
 Any accessories which might
decrease the total seated weight on
the front passenger seat are attached
to the front passenger seat.
The front passenger front and side air
bags and knee air bags, and the seat
belt pretensioner system will
deactivate if the front passenger air
bag deactivation indicator light
illuminates.

Do not increase the total seated
weight on the front passenger seat:
When an infant or small child sits on
the front passenger seat, increasing the
total seated weight on the front
passenger seat is dangerous. The front
passenger seat we ight sensors will
detect the increased total seated
weight, which could result in the
unexpected deployment of the front
passenger front and side air bags and
knee air bags, and seat belt
pretensioner system in an accident and
may cause serious injury. Increasing the
total seated weight on the front
passenger seat could result in the front
passenger front and side air bags and
knee air bags, and seat belt
pretensioner system deployment in an
accident under the following
conditions, for example:
 Luggage or other items are placed on
the seat with the child in the
child-restraint system.
 A rear passenger or luggage push or
pull down on the front passenger
seatback.

NOTE
Always stop the engine and lock the
doors. In addition, to prevent theft of
valuables, do not leave them inside
the cabin.
If the key is left in the following areas
and you leave the vehicle, the doors
may be locked depending on the
radio wave conditions even if the key
is left in the vehicle.
Around the dashboardIn the storage compartments such
as the glove compartment or the
center console
On the rear parcel shelf (4–door)Next to a communication device
such as a mobile phone
When the ignition is switched to
ACC or ON, the vehicle lock-out
prevention feature prevents you from
locking yourself out of the vehicle.
All doors, fuel-filler lid, and liftgate
will automatically unlock if they are
locked using the power door locks
with any door or the liftgate open.
The vehicle lock-out prevention
feature does not operate while the
ignition is switched off.
When all doors, fuel-filler lid, and
liftgate are locked using the power
door lock with any door or the
liftgate/trunk lid open, the closed
doors, fuel-filler lid, and liftgate are
locked. After that, when all doors
and the liftgate/trunk lid are closed,
all doors and the liftgate/trunk lid
are locked. However, if the key is
inside the vehicle, all doors, fuel-filler lid, and liftgate are
automatically unlocked.
(With the advanced keyless
function)
The beep sound is heard for about
10 seconds to notify the driver that
the key has been left in the vehicle.
(Without the advanced keyless
function)
The horn sound is heard twice to
notify the driver that the key has
been left in the vehicle.
(Door unlock (control) system with
collision detection)
This system automatically unlocks the
doors, fuel-filler lid, and liftgate in
the event the vehicle is involved in an
accident to allow passengers to get
out of the vehicle immediately and
prevent being trapped inside. While
the ignition is switched ON and in
the event the vehicle receives an
impact strong enough to inflate the
air bags, all the doors, fuel-filler lid,
and liftgate are automatically
unlocked after about 6 seconds have
elapsed from the time of the
accident.
The doors, fuel-filler lid, and liftgate
may not unlock depending on how
an impact is applied, the force of the
impact, and other conditions of the
accident.
If door-related systems or the battery
is malfunctioning, the doors, fuel-filler lid, and liftgate may not
unlock depending on your vehicle
type.
