Airbag Triggering Conditions

The airbag is designed to be triggered
under the following conditions: severe
frontal collision accidents and some
special collision accidents.

In case of minor front collision, side
collision, rear collision or roll-over,

generally airbag system won’t be
triggered. In such accidents, the seat
belt, if fastened, can protect the driver
and passenger in the normal way.

The decisive factor for triggering the
airbag system is the result of judgment
through

comprehensive

intelligent

comparison of the deceleration curve,
which is produced in a collision and
acquired by the electronic control unit
(ECU), with the set value. If the signals,
such as deceleration, produced and
detected in the collision is lower than the
set reference value in the ECU, the
airbag won’t be triggered even though
the car may have been severely
deformed in the accident.

ECU setting of BYD airbag system has
taken various common misuse and
domestic road conditions into full
consideration. However, as causes and
conditions of crashes are widely variable,
for the sake of your safety, please
strictly abide by this manual to use the
car

correctly

and

avoid

misuse;

otherwise, the expected protection effect
of the airbag cannot be ensured.

Protection Principle of Airbag

Once the airbag system is triggered, air
will be immediately inflated into the
airbag and make it expand rapidly in
front of the driver and the passenger.
The occupants will fall into the expanded
airbag and the forward inertia is reduced,
thereby reducing the severity of injury to
their heads, necks and chests.

The specially designed airbag can, after
expansion,

absorb

energy

when

pressed by the body of the driver and
the passenger in an accident, and
discharge the air out at a certain rate so
as to reduce the force applied by the
airbag on the occupants, further
relieving injuries to them. After accident,
the airbag is deflated as air in the bag is
discharged, so the front view of the
driver is not affected.

The airbag can be expanded within a
few fractions of a second so as to
provide extra protection for the driver
and the passenger in accidents.

Airbag expansion can produce a rather
loud noise but, in general, won’t cause
injuries (the possibility of ear ringing or
temporary deafness exists, but these
problems can recover soon). The gas
produced in deployment of the airbag
may have some smell but won’t lead to
occupant poisoning. Normally a little
smoke will be emitted after the airbag is
deployed. This is not indication of a fire,
so please do not worry about it.

● In case of the conditions described
in the figures above, SRS airbag may
not be deployed.

Note

● The airbag is designed to match
certain vehicle models, any variation
in suspension, tire size, bumper,
chassis

and

other

original

equipments may adversely affect the
function of the airbag. In addition, it
is strictly prohibited to apply any
airbag parts to other vehicle models;
otherwise it might lead to airbag
system failure, resulting in personal
injuries.

● In driving, please wear the seat belt
properly and maintain a correct
sitting posture. In driving, if you do
not wear the seat belt and lean
forward or sit in an incorrect posture,

airbag deployment may increase the
risk of injuries in accidents.

● It’s very important for the driver to
maintain a distance of at least 25cm
between the chest and the steering
wheel,

which

allows

maximum

protection when the airbag system is

triggered. That is to say, it’s
necessary to adjust the front seats
and the headrest according to the
figure of each occupant; in addition,

the driver’s arms shall only bend
slightly, stretching nearly straight.

● Do not paste or cover the surface of
the steering wheel lid or the surface
near the airbag on the right of the
instrument panel with any objects;
and do not make any other decorative
treatment at such places. There two
places shall be cleaned only with dry
or slightly wetted cloth, and it is
prohibited to knocked at such places
violently.

● It is prohibited to let child sit in the
front seat without protection. If a
collision triggers the air bag, the
child passenger may get seriously
injured or even killed.

● Don’t leave any person, animal or
object between the driver/front seat
passenger

and

the

air

bag

deployment range. It is extremely
dangerous for an adult to hold a child

on the lap.

● Any accessories, such as phone
holder, cup holder and ashtray, shall
not be installed on airbag decoration
lid or within airbag deployment
range.

Otherwise

in

airbag

deployment there may be increased
risk of personal injury.

● Don’t make any modification to any
part of the airbag system, including
labels.

● All operation to the airbag,
including removal of airbag required
for repairing other parts (such as
detachment of the steering wheel),
can only be made by BYD authorized
service stations.

● The airbag system must be
replaced in a BYD authorized service
station within 15 years as of the date
of

delivery

(manufacture

date

indicated in the quality certificate and
Repair Manual). If the airbag is
replaced before that date, it shall be
recorded in the Repair Manual.

service

stations

have

a

good

knowledge of these regulations and
the detailed disposal procedure is
also available on Repair Manual.

● The air bag system has strong
resistance

capacity

against

the

surrounding

electromagnetic

interference.

However,

to

avoid

accidents, please do not use the
vehicle beyond the electromagnetic
environment specified by national
laws.

● The airbag system of BYD G3 has
taken various misuses and road
conditions into full consideration.
However, avoid serious impact at the
bottom of the car and do not drive
toughly in poor road conditions in
order to prevent accidents.

Disable Airbag

According to applicable regulations,
airbags for the driver and the front
passenger can only be disabled in the
cases below:
● When it is impossible to keep a 25cm

distance between the center of the
steering wheel and the chest of the
driver even though the driver seat is
adjusted properly.

● When special equipment needs to be

installed for the disabled within the
range of the steering wheel.

● When adjustment of the front seat is

required for specific reasons, the seat
cannot be kept within the scope set by
the manufacturer.

Disabling of the airbag system shall be
conducted by a BYD authorized service
station. After a certain airbag is disabled,
the BYD authorized service station will
paste a label on the corresponding
position and make a record in Repair
Manual.

Tips

If the air bag system needs to be
disabled on special occasions,
please have it done in a BYD
authorized

service

station.

Otherwise, it may cause serious
injuries or death!
