2019 MAZDA MODEL 3 HATCHBACK sensor

▼If You Must Use th
e Front Seat for
Children
If you cannot put all children in the rear
seat, at least put the smallest children in
the rear and be sure the largest child up
front uses the shou lder belt over the
shoulder.
NEVER put a rear-fac ing child-restraint
system on the front passenger seat whether
your vehicle is equipped with an occupant
classification sensor or not.
This seat is also not set up for tethered
child-restraint systems, put them in one of
the rear seat positions set up with tether
anchors.
Likewise the ISOFIX/LATCH
*1
child-restraint system cannot be secured in
the front passenger's seat and should be
used in the rear seat.
Do not allow anyone to sleep against the
side window since your vehicle has side
and curtain air bags, it could cause serious
injuries to an out of position occupant. As
children more often sleep in cars, it is
better to put them in the rear seat. If
installing the child-restraint system on the
front seat is unavoidable, follow these
instructions when using a front-facing
child-restraint system in the front
passenger's seat.
*1 ISOFIX (Mexico)/LATCH (Except Mexico)
NOTE
To check if your front seats have side air
bags:
Mazda vehicles equipped with side air
bag will have a "SRS AIRBAG" tag on
the outboard shoulder of the front seats.
To check if your vehicle has curtain air
bags:
Mazda vehicles equipped with curtain
air bag will have an "SRS AIRBAG"
marking on the window pillars along the
roof edge.
WA R N I N G
Always move the front passenger seat as
far back as possible if installing a
front-facing child-restraint system on it is
unavoidable:
As your vehicle has front air bags and
doubly so because your vehicle has side air
bags, a front-facing child-restraint system
should be put on the front passenger seat
only when it is unavoidable.
Even if the front passenger air bag
deactivation indicator light illuminates,
always move the seat as far back as
possible, because the force of a deploying
air bag could cause serious injury or death
to the child.
Never use a rear-facing child-restraint
system in the front seat with an air bag
that could deploy:
Rear-facing child-restraint systems on the
front seat are particularly dangerous.
Even in a moderate collision, the
child-restraint system can be hit by a
deploying air bag and moved violently
backward resulting in serious injury or
death to the child. Even though you may
feel assured that the front passenger air
bag will not deploy based on the fact that
the front passenger air bag deactivation
indicator light illuminates, you should not
use a rear-facing child-restraint system in
the front seat.

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 in dicators. These indicators are
visible in the area where the air bags are
installed.
The air bags are insta lled 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
bag 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 p arts of the body.
Hold the driver in a position which
allows better control of the vehicle.

Do not hang net bags, map pouches or
backpacks with side straps on the front
seats. Never use seat covers on the front
seats. Always keep the side air bag modules
in your front seats free to deploy in the
event of a side collision.
Do not attach objects on or around the
area where a curtain air bag deploys:
Attaching objects to the areas where the
curtain air bag activates such as on the
windshield glass, side door glass, front and
rear window pillars and along the roof
edge and assist grips is dangerous. In an
accident the object could interfere with the
curtain air bag, which inflates from the
front and rear window pillars and along
the roof edge, impeding the added
protection of the curtain air bag system or
redirecting the air bag in a way that is
dangerous. Furthermore, the bag could be
cut open releasing the gas.
Do not place hangers or any other objects
on the assist grips. When hanging clothes,
hang them on the coat hook directly.
Always keep the curtain air bag modules
free to deploy in the event of a side collision
or roll-over accident.
Do not touch the components of the
supplemental restraint system after the air
bags have inflated:
Touching the components of the
supplemental restraint system after the air
bags have inflated is dangerous.
Immediately after inflation, they are very
hot. You could get burned.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 vehi cle'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 9-9) 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 al ong 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 Deal er 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.

How the SRS Air BagsWo r k
▼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 Bel
t 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 2-68).
▼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 2-68).
(With Front Passenger Occupant
Classification System)
The driver's dual-stag e 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.

Mazda3_8HE9-EA-18K_Edition1 2018-10-17 19:05:10

▼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 Crite
ria" (page 2-68).
(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 2-71).
▼ 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 2-68).
▼ 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 2-68).
