function of airbag.

Conditions of activating SRS airbag
system
The SRS airbag system is designed to
activate in response to a severe frontal
impact or other special impact.
The SRS airbag is not designed to inflate if
the vehicle is involved in a low-speed frontal
collision, side or rear collision, or if it is
involved in a rollover. But seat belts will
protect occupants.
When impact occurs, the SRS ECU will
analyze the acceleration to ensure whether it
reaches the reference value to activate the
airbag. If it doesn’t reach the value, the airbag
will not be activated, even though the vehicle
is distorted heavily in the accident.
The BYD F3 airbag ECU is designed basing

on most road conditions and wrong usage of
the vehicle. However, please observe this
manual to drive your vehicle to ensure your
safety because man reasons may lead to
accidents.

The protected process of the airbag
While the airbag system is activated, the gas
is emitted in the airbag, and the airbag
inflates quickly. The driver and passenger are
protected by the airbag from being hurt upon
the head, neck and the chest when he/she
gets into the airbag while the moving inertia is
buffered.
When the airbag hustles the body, it can
absorb the energy, and make the gas
exhaust from the bag at some speed ratio.

This way can reduce the injury to the person
farther. After the accident, the gas in the bag
will be exhausted completely. Therefore, it
will not block the front visual field.
The airbag deploys at some ms, thus
carrying out extra protection towards drivers
and passengers.
While the airbag is deploying, there is a large
sound. Generally, it does not cause the injury.
Maybe it can cause the tinnitus and cause
you to lose hearing temporarily. However,
these are the unabiding and you will recover
quickly. The gas from the airbag may give
some smell and affect your appetite, but it
does not cause the driver or passengers toxic.
While the airbag is inflating, it may emit some
smoke. It is normal.

F3/F3R OWNER’S MANUAL

Conditions when the SRS airbag does not
deploy

The SRS airbag is not designed to inflate if
the above conditions occur.
The examples are referred to the above
illustrations.

F3/F3R OWNER’S MANUAL

Conditions when the SRS airbag deploys

The SRS front airbags may deploy if
the above conditions occur.

The SRS front airbags may deploy if a
serious impact occurs to the underside
of your vehicle. For examples, refer to
the above illustrations.

NOTICE

●

The SRS airbag system is designed
only for this module. Changes of
suspension system, tires, bumpers,
chassis, and other parts will bring
harmful impact. In addition, do not
replace any part of SRS airbag system
to other vehicles. Otherwise, the SRS
airbag system will be invalid.

●

While driving, please wear the seat
belt and sit at correct pose. If you do
not tie the seat belt, lean forwards or

Please keep 25 cm between driver’s
chest and steering wheel. In this way
the SRS airbag system will protect
driver best. It also means that front
seats and head-rest should be
adjusted in accord with each
passenger’s figure. Besides, the
driver should keep elbow bended
slightly even close to straight.

●

Do not affix anything onto the cover

of steering wheel or the surface of
front passenger airbag position.
Those two places must be cleaned
with dry dishcloth. Do not knock
those places seriously.

● Children are not allowed to sit at the

front seat without child restraint.
Since the front airbag inflates with
considerable speed and force, the
child may be seriously injured or
killed.

● There shouldn’t be any person,

animal or object between the SRS
airbag and the driver or the
passengers at the front seat. Do not
hold a child on your lap or in your
arms. It would be extremely

on or in front of the dashboard or
steering wheel pad that houses the
front airbag system, or the possibility

● Any operation to the SRS airbag

system or repair relating to this

system must be operated by BYD
AUTO service station.

years since the manufacture date
marked on the auto certificate and
maintenance manual. This must be
operated by BYD AUTO service
station. For replacing some parts of
the SRS airbag system, please make

● The SRS airbag system only

provides one time protection. After
deployed or damaged, it must be
replaced for a new one.

●

While you transfer your vehicle to
other person, give the on-vehicle files
to the new owner. If the SRS airbag
system is closed, give this file to the
new owner, too.

●

To dispose the parts of the SRS
airbag system, observe the safety
order and disposal process. BYD
service station is familiar with these
regulations and detailed disposal
descriptions are available on the
maintenance manual.

●

The SRS airbag system has excellent
anti-magnetic ability. However, to
avoid the suddenness,do not drive the
vehicle in some area where the
magnetic intensity is beyond the state
rule.

●

The SRS airbag system is fitting for
many road conditions and wrong
operation to the vehicle. But to avoid
the suddenness, please do not make
serious crash to the chassis, or do not
drive the vehicle gruffly in rough road
conditions.

but the distance of 25 cm between the
driver’s chest and steering wheel can
not be kept.

Special equipment at area of steering
wheel for handicapped is needed to be
installed.

The front passenger seat is adjusted
due to some reason. However, the
position set upon delivery can not be
guaranteed.

Please contact your BYD AUTO service
station to close the SRS
airbag system. When closing an airbag,

please mark at a right position and record on
the service manual.

CAUTION

In some situations, the SRS airbag
system can be closed. To do so,

station. Otherwise, it may cause
serious injury or death.
To resume the protection function of
the SRS airbag system, please re-start
your closed SRS airbag system as
soon as possible.

Other situations
●

Please read this manual carefully. If you
want to sell or dispose the vehicle,
please tell the new owner or the
disposal factory that this vehicle has the

SRS airbag system and suggest them to
read this manual thoroughly.

●

While the airbag is deploying, avoid
contacting the airbag module. Otherwise,
it may cause the scald or discomfort.
Contact your BYD AUTO service station
to replace with a new SRS airbag as
soon as possible if it has been activated
before.

●

The SRS airbag system will be activated
only upon some

situations. Therefore, if the SRS airbag
system fails to work, it may not be the
problem of the system itself. Abnormal
repair or untimely repair towards the
damaged parts of the vehicle may affect
the SRS airbag system.
