—Fastening front and rear seat belts

3-point Seat Belt

Adjust the seat to desire position and
sit up straight and well back in the
seat. To fasten your belt, pull it out from
the retractor and insert the tab into the
buckle.

Tug on the belt to make sure the belt
is securely latched .Check that the belt
is not twisted, A twisted belt can cause
serious injuries in a crash.
The seat belt length automatically
adjusts to your size and the seat
position.
The retractor will lock the belt during a
sudden stop or in crash. It also may
lock if you lean forward too quickly. A
slow, easy move will be allowed, and
you can move around freely.
If the seat belt cannot be pulled out of
the retractor, firmly pull the belt and
release it. The seat belt will be able to
pull out from the retractor.

WARNING

y

After inserting the tab, make sure

the belt is securely latched and

SRS driver and front

passenger airbags

The SRS (Supplemental Restraint
System) front airbags provide further
protection for the driver
and front passenger in addition to the
primary safety protection provided by
the seat belts.
In response to a severe frontal
impact,the SRS front airbags work
together with the seat belts to reduce

injury by inflating. The SRS front
airbags reduce injuries mainly to the
driver’s or front passenger’s head or
chest caused by hitting the vehicle
interior.
The front passenger airbag is activated
even with no passenger in the front
seat.
SRS is an auxiliary device for seat belt,
which can protect passengers’ head
and chest from serious injury in severe
front crashes.
SRS cannot supersede seat belts and
is only a part of the whole passive
safety protection system of the vehicle.
Note that SRS has the best protection
performance only when working
together with fastened seat belts. For
the safety of yourself and your family,
please pay special attention to the
“warning” and “Notice” in this section.

WARNING

y

The SRS airbag system is

designed only as a supplement
to the primary protection of the
driver side and front passenger
side seat belt systems .The front
seat occupants can be killed or
seriously injured by the inflating
airbags if they do not wear the
available seat belts properly.
During sudden braking just
before a crash, an unrestrained
driver or front passenger can fall
forward into direct contact with
or close proximity to the airbag
which may then deploy during
the collision.To ensure maximum
protection in an accident, the
driver and all passengers in the
vehicle must wear their seat belts

properly. Wearing a seat belt during
an accident reduces the chances
of death or serious injury or being
thrown out of the vehicle.

y

I m p r o p e r l y s e a t e d a n d / o r

restrained infants and children
can be killed or seriously injured
by the deploying front airbags.
An infant or child who is too
small to use a seat belt should
be properly secured using a child
restraint system. BYD strongly
recommends that all infants and
children be placed in the rear
seat of the vehicle and properly
restrained. The rear seat is the
safest for infants and children.

y

Please keep sitting in correct

posture so that you can get the
maximum protective effect of the
seat belt and SRS.

y

Do not dismount parts of SRS

without permission.

The airbag SRS is designed to activate
when the vehicle sustains sufficient
longitudinal deceleration in severe
(usually frontal) collisions where the
forward deceleration of the vehicle
exceeds the designed threshold level.
The airbags did not inflate in a collision
does not mean that something is wrong
with the system . Rather, it means the
forces were not sufficient to cause
activation. Airbags can inflate in frontal
and near frontal collisions, but not
rollover, side impact, or rear impacts.
Always wear your seat belts properly.

System Components

The SRS consists of the following
components and their locations are
shown in the illustration:
1. SRS warning light
2. Airbag module for front passenger (
airbag and inflator)
3. SRS electronic control unit (ECU)
4. Airbag module for driver (airbag and
inflator)
5. Impact sensor

SRS ECU consists of a safing sensor
and airbag sensor.

SRS Airbag Warning Indicator

SRS Airbag system is monitored by
ECU and integrated self-diagnosis
function. Its status is indicated by
warning indicator on the instrument
panel.
●Airbag warning light will be on for
about 5 seconds after turning on
ignition switch ,which indicates that the
system is normal.
This warning indicator monitors SRS
airbag ECU, impact sensor, inflator,
warning light, connecting wire and
power supply. (For details, please refer
to “Maintenance Indicator lights and
Warning Buzzer” in Section 1-5)

WARNING

If any of the following

conditions, airbag system may
have Malfunction troubles:

y

The indicator is not on when

turning on the ignition switch.

y

Turn on the ignition switch, and 5

seconds later, the warning light
remains on or it flashes and goes
on again after going out.

y

The indicator is on after turning

off the ignition switch.

y

The indicator comes on or flashes

while driving.

WARNING

If any SRS trouble indicated by
warning light, please contact your
BYD authorized dealer for inspection
as soon as possible. Otherwise, the
airbag system can not work properly
in case of accident

SRS Airbag Triggering Conditions
The airbag is triggered under the
following conditions: severe frontal
crashes and some special crashes.
In case of minor front collision, side
collision, but it won’t be triggered by
rear collision or roll-over, airbag system
generally won’t be triggered.. In such
accidents, fastening the seat belt, can
protect the driver and passenger in the
normal way.
The decisive factor for triggering SRS

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.
BYD SRS ECU on setting 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 vehicle
correctly and avoid misuse; otherwise,
the airbag may be incapacity.

F3DM Owner’s Manual

Protection Principle of SRS Airbag
If an impact results in a forward
deceleration beyond the designed
threshold level , the system triggers
the airbag inflators. At this time a
chemical reaction in the inflators very
quickly fills the airbags with non–toxic
gas to help restrain the froward motion
of the occupants. The front airbags
then quickly deflate, so that there is
no obstruction of the driver’s vision
and it should be necessary to continue
driving. When the airbags inflate, it is
normal to notice a smoke-like, powdery
residue or smell the burnt propellant.
They produce a loud noise and release
some smoke and residue along with
non–toxic gas. This does not indicate a
fire. This smoke may remain inside the
vehicle for some time, and may cause
some minor irritation to the eyes, skin
or breathing. Be sure to wash off any

residue as soon as possible to prevent
any potential skin irritation with soap
and water. You shall exit the vehicle
safely immediately if available.
While the system can reduce serious
injuries, it may also cause minor
abrasions, swelling or temporary
hearing loss. Because airbags must
inflate rapidly and with considerable
force, there is the risk of death or
serious injuries such as fractures,
facial and eye injuries or internal
injuries, particularly to occupants who
are not properly restrained or are other
out of position at the time of airbag
deployment. Thus, it is extremely
important that occupants be properly
restrained as far away from the airbag
cover as possible while maintaining
vehicle control.
Parts of the airbag module (steering
wheel hub, airbag cover and inflator)

may be hot for several minutes
after deployment, so do not touch!
The airbags inflate only once. The
windshield may be damaged by the
inflating airbag.

WARNING

Sitting too close to a front airbag
can result in serious injury or death
if the front airbags inflate.
BYD strongly recommends that:

y

The driver sit as far back as

possible from the steering wheel
while still maintaining control of
the vehicle.

y

The front passenger sit as

far back as possible from the
dashboard.

y

All vehicle occupants be properly

restrained using the available
seat belts.

WARNING

Do not sit on the edge of the seat
or lean against the dashboard when
the vehicle is in use, since the front
airbags inflate with considerable
speed and force. Otherwise, you
may be killed or seriously injured.
Sit up straight and well back in the
seat, and always use your seat belt
properly.

WARNING

Do not allow a child to stand up or
to kneel on the front passenger
seat, since the front airbag inflates
with considerable speed and force.
Otherwise, the child may be killed
or seriously injured.
_ Do not hold a child on your lap or
in your arms.

WARNING

Do not put anything on or over the
airbag module . Placing objects on
or over the airbag inflation area may
cause those objects to be propelled
by the airbag into your face and
torso causing serious injury.

seat belt properly and maintain a
correct sitting posture. Otherwise,
airbag deployment may increase
the risk of injuries in accidents.

y

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 head
restrain according to the figure
of each occupant; in addition,
the driver’s arms shall only bend
slightly, stretching nearly straight.

y

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. These two places
shall be cleaned only with dry
or slightly wetted cloth, and it
is prohibited to knock at such
places violently.

y

Never allow children to sit on the

front seat without protection. If
a collision triggers the air bag,
the child passengers may get
seriously injured or even killed.

y

Don’t leave any person, a nimal

or object in the deployment range
of driver/front seat passenger air
bag. It is extremely dangerous
for an adult to hold a child on the
lap.
