remind user that the function is
normal rather than fault noise!

Friendly Tips

When the child protection
module of the rear seat is
activated, please pull out the
ribbon completely and apply
appropriate force to avoid
damage.

Indicator that front passenger’s
seat belt isn’t fastened

If the F7

passenger’s car you

purchased is provided with seat
belt alarm sensor, the switch group
on the central control panel of the
instrument platform has an

indicator that

front passenger’s seat

belt isn’t fastened (black shaded area
in above figure). It is used together with
the seat belt. When a passenger sits
on the front passenger's seat but
doesn’t fasten the seat belt, it is lit and
accompanied with alarm sound to
remind the driver and the passenger.
When the front passenger fastens the
seat belt, the indicator goes out. If no
passenger sits on the front passenger’s
seat, the indicator is off.

Friendly Tips



Seat belts equipped on the

vehicle are designed for
adults and should be
applied to children with
caution.



It is suggested to seat

children in the rear seat
with child seat and fasten
the seat belt for
protection. Do not let the
children sit in the front
passenger’s seat.



Do not place children on

your knees or hold them
in your arms, or else it
may result in serious
injury or even death of the
children. Arranged in the
front seat or the rear seat,
children should not be
allowed to stand or kneel.
In emergency braking or
crashes, unprotected
children may be seriously
injured.



When the vehicle is

driving, passengers in it
should sit in the seats and
fasten the seat belts
correctly; otherwise, in
emergency braking or
crashes, people in the car
are more prone to severe
injuries.



At the same time, a seat

belt can only be used by
one person. It’s not
allowed that two or more
persons share one seat
belt

—even for children.



Do not incline the seat

back over. The seat belt
has the best protection

BYD F7-1, F7-2, F7-3

Owner’s Manual

Instrument and Controller Operation 1-24

effect when the seat back
is in the upright position.



Check the seat belt

regularly to see whether it
has cutting lines, worn or
loose parts. Damaged
parts should be replaced
with new ones; the system
should not be
disassembled or modified.



After serious crashes, the

seat belt system
(including screws) should
be replaced, even if the
damage is not so marked.
When the spring bolt is
inserted, make sure that
the spring bolt and buckle
are fixed and the seat belt
isn’t twisted.



Do not leave small

objects, e.g. coins, paper
clips, etc. in the buckle.
They may affect the
connection of the tab and
the buckle.



If the seat belt functions

abnormally, immediately
inform BYD authorized
service stations. Before

repaired, it cannot protect
passengers.



Keep a straight posture

and stay back, keep a
proper distance with the
steering wheel and
instrument panel, so as to
play the maximum
protective effect of seat
belt and SRS.



It should be made sure

that the shoulder seat belt
passes over the shoulder
center.



The seat belt should be

somewhat far away from
the neck without sliding
off the shoulder.
Otherwise, its protection
effect may be reduced and
severe human injuries
may be caused in crash
accidents.

Airbag

Airbag is the supplemental restraint
system, which is a supplement to seat
belts. The airbag system can provide
extra protection for heads and chests
of the driver and passengers and
reduce casualties in severe frontal
crashes.

Friendly Tips



Please keep the seat belt

fastened when the vehicle
is driving!



Please keep sitting in a

correction posture so that
the protection effect of the
seat belt and the airbag
system can be taken into
full play.



For children, the rear seats

are the safest position!



Do not dismount parts of

the airbag without
permission!

Airbag triggering conditions
The airbag is designed to be
triggered under the following
conditions: frontal (side) collision
accidents may trigger the airbag
system; special collision accidents
may trigger the airbag system.
In general, the airbag system won’t
be triggered in mild front collision or
side collision accidents, in rear end
collisions or in turn-over accidents.
In such accidents, the seat belt, if
fastened, can protect the driver in
the normal way.
The decisive factor for triggering
the airbag system is the
comprehensive intelligent
comparison and judgment of the
deceleration curve produced in a
collision and acquired by the

electronic control unit (ECU) and the
set value. If the automobile
deceleration signal 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
takes various common misuse and
domestic road conditions into full
consideration. However, reasons and
conditions of crashes are variable, so,
for your safety, please abide strictly by
this manual, use the automobile
correctly and avoid misuse; otherwise,
the expected protection effect of the
airbag cannot be ensured.

Airbag warning light

The airbag system is monitored by an
electronic control unit and provided
with self-diagnosis function. The
system state can be indicated by a
warning light on the instrument panel:
Each time after the ignition switch is
turned on, the airbag warning light
turns on for about 5s and then goes out
for longer than 5s, and the system can
be considered as normal.
If the airbag has already been
deactivated by a BYD authorized
service station, but the warning light
still turns on and goes out as above, it

means the airbag has no protection
function.

Friendly Tips

In case of faults, have the
airbag system checked
immediately in a BYD
authorized service station.
Otherwise, in accidents, partial
or all function of the airbag
system may be affected!

Warning



The airbag is designed to

match the certain vehicle
models. Any changes of
the suspension, the tire

size, the bumper, the
chassis and other original
equipment 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 safety
airbag system failure,
resulting in personal
injuries.



During driving, please

wear the seat belt correctly
and maintain a correct
sitting posture. If you
haven’t worn the seat belt
and lean forward or sit in
an incorrect posture, the
risk of injuries in accidents
with airbag expansion may
be increased.



It’s very important for the

driver to maintain a
distance of at least 25cm
between the chest and the
steering wheel since only
by doing so can the
maximum protection effect
be provided when the

system is triggered.



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 or do any
other decorative
treatment. cleaned with
only dry or slightly wetted
cloth and should not be
knocked at violently



Don’t let child passenger

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



Telephone supports, cups,

ashtrays, etc. can
increase the risk of
injuries in accidents with
airbag inflation.

The side airbags and side air
curtains expand at fast speed
and great force. In vehicles
equipped with side airbags
and side air curtains, never
lean against the door, or else

BYD F7-1, F7-2, F7-3

Owner’s Manual

Instrument and Controller Operation 1-28

it may result in serious injury
or even death.



Do not install other

accessories or items
within the effective scope
of the side air curtain,
such as windshield glass,
side door glass, “A” pillar
trim panel, roof,

“B” pillar

trim panel,

“C” pillar trim

panel and auxiliary
handle, because the great
force of side air curtains
will shoot off the
accessories or items or
side air

curtains can’t

expand, resulting in
serious injury or even
death.



Do not modify or replace

the trim of the seats with
or without side airbags,
because these changes
will interfere with the
normal expansion of side
airbags, cause system
failure or unexpected
expansion of side airbags,
resulting in serious injury
or even death.



Do not disassemble or

repair the A pillar, roof, B
pillar, or C pillar with side
air curtain. These changes
may cause system failure
or unexpected expansion
of air curtain, leading to
serious injury or even
death.



Never modify any

component of the air bag
system, including the
corresponding label. Any
operation of the airbag
should be performed by
BYD authorized service
station.



The airbag system must

be replaced in a BYD
authorized service station
within 10 years as of the
date of manufacture. The
maintenance manual has
the record if certain part of
the airbag system had
been replaced.



The air bag can only

provide protection once.
Once the air bag is
triggered or damaged, the

system must be replaced.



Please hand our materials

to the next owner of the
vehicle in transfers.
Please note that if the
airbag is shut down, the
information should be
informed the next owner
of as well.



When disposing the parts

of the vehicle or the airbag
system, please comply
with correlative safety
regulations and disposal
procedures.



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.
