Seats

In driving, all passengers shall lean on
seatbacks which has been adjusted to
vertical position, and use seat belts
correctly.

Tips

● The car shall not start until all

passengers has been seated well.
Do not sit on folded seatback,
baggage

or

in

trunk

as

in

emergency braking or collisions,
passengers who have not been
seated straightly or have not
buckled the seat belts may be
seriously injured.

● In driving, do not let passengers

stand up or move among seats;
Otherwise, they may be seriously
injured in emergency braking or
collisions.

Front Seats

Notice on Seat Adjustment
Adjust the driver seat to include the
pedals, the steering wheel and the
instrument panel controller into the
easy-control range of the driver.

Tips

● Do not adjust the seat in driving, as

sudden movement of the seat may
cause the car out of control.

● In seat adjustment, take care to

avoid collision between the seat
and passengers or baggage.

● After the seat adjustment, shake it

to make sure it is locked up at its
position.

● After seat adjustment, lean

backward to make sure the seat
back is locked up at its position.

● Do not place things under the seat;

this may affect the seat lockup
mechanism or push the seat
adjustment rod randomly, which
may cause movement of the seat
and result in losing control of the
car.

● In seat adjustment, do not put your

hand under the seat or near moving
parts; otherwise your hand or
fingers may be injured.

Tips

To reduce the dangerous possibility
that the passenger slides down the
buckle of seat belt in collision, do not
make the seat back over slant. Seat
belts can provide the maximum
protection in front and rear collision
accidents

if

the

driver

and

passengers sit straight and lean on
the seat backs. If the passenger is
lean on seat back slantwise, the belt
may slide along the hip and pose
pressure to abdominal part. In
front-collision

accidents,

over

obliquity of the seat may increase the
risk of human injuries.

Seat Belts

Notice on Seat Belt:
BYD strongly require that the driver and
passenger in the vehicle wear seat belts
at any time to reduce the possibility of
injuries in accidents.

Seat belts equipped on the vehicle are
designed for adults.

Children shall be seated in rear seats
with seat belt
applied properly. Statistics of accidents

shows that children seated in rear seats
are better protected than children
seated in front seats.
If a child has to be seated in the front
seat, the seat belt shall be properly
applied. In accidents, the quickly
deployed seat belt may cause severe
injury and even death to children if the
seat belt is not fastened correctly.

In front seats or rear seats, children
shall be prevented from standing up or
kneeling down. In emergency braking or
crashes, unprotected children may be
seriously injured. Similarly, do not seat
children on your legs as in this way they
can not be sufficiently protected.

Tips

In driving, passengers shall be
seated on the seats and fasten the
seat belts correctly. Otherwise, in
emergency braking or crashes,
passengers in the car are more
prone to be severely injured.

BYD G3 AUTO Owner’s Manual

25

Follow the instructions below when
using seat belt:

● One seat belt shall be applied to one

passenger only. It’s not allowed that two
or more passengers share one seat
belt

—even for children.

● Do not over slant the seat back. The
seat belt provides the best protection
when the seat back is in the upright
position. (Refer to instructions on seat
adjustment)

● Pay attention to not damaging the belt
or other part of the seat belt. Prevent
them from being caught in the seat or
the door.

● Check the seat belt regularly to see
whether it is cut, worn or loosen.
Damaged parts shall be replaced with
new ones. Do not disassemble or modify
the system.

● Keep seat belt clean and dry. For
cleaning, use neutral soap water or
warm water. Bleaching agents, dyes or
grinding cleaning agents are not suitable
for seat belt cleaning - they may
severely

reduce

the

protection

performance of the seat belt. (See

―Interior Cleaning‖ in the manual).

● After serious crashes, the seat belt
system (including bolts) should be
replaced, even if the damage is not
obvious.

Tips

Seat belt is designed for adults,
so it is not suitable for child. It is
recommended that child

be

seated in rear seats.

3-point Seat Belt

Adjust the seat according to your
demand, and sit upright leaning on
the seat back. To fasten seat belt, pull
it out of the retractor and insert the
tab into the buckle.

A

clicking

sound

indicates

well

connection of the seat belt.

Length of seat belt can be automatically
adjusted according to the passenger
figure and the seat position.

In emergency braking or crashes, the
retractor will lock the seat belt. If the
body inclines forward fast, it will also be
locked. Slow and steady operation can
drag out the seat belt so that you can
feel free.

Tips

● After the tab is inserted, make sure

it is locked up to the buckle firmly
and the seat belt is not twisted

Do not leave small objects, such as

coins, paper clips, etc. in the
buckle, as they may affect the
proper connection of the tab and
the buckle.

● If seat belt functions abnormally,

immediately inform BYD service
station. Before repaired, do not sit
on the seat with damaged seat belt
as it cannot protect passengers
and may cause injuries.

If you cannot pull the seat belt out from
the retractor, drag to tighten it and then
release it. Then, you can pull it out from
the retractor.

When shoulder safety belt for rear seat
is extended fully, retract it slightly and it
will be locked at that position prevented
from extension. To release the
shoulder safety belt once again, retract it
completely and then pull it out again.

BYD G3 AUTO Owner’s Manual

BYD G3 AUTO Owner’s Manual

27

Tips

Make sure shoulder safety belt at the
middle of your shoulder. Keep the
belt away from neck, but also prevent
it from falling off the shoulder.
Otherwise the belt’s protection
performance will be reduced in
accidents, which may cause severe
injury to passengers.

2-point Seat Belt

Sit upright in seat and lean on the
seat back. Fasten the seat belt and
insert the tab into the buckle.

A clicking sound indicates well
connection of the seat belt.

If the seat belt is not long enough, keep
the tab perpendicular to the seat belt
and pull the tab. Keep the safety belt as
low as the hip.

Retract the excessive length of the
seat belt and adjust its position.

To shorten the seat belt, pull the unfixed
end. Keep the lap belt as low as hip

– it

is not allowed to lock it around waist,
and then adjust its position.

Tips

● Lap belt which is high above waist
or loose may cause severe injury to
the passenger in collision and other
accidents when the passenger slip
downward. Try to keep lap belt as
low as hip.

Tips

● After the tab is inserted, make
sure it is locked up to the buckle
firmly and the seat belt is not
twisted
● Do not leave small objects, such
as coins, paper clips, etc. in the
buckle, as they may affect the

Airbags

for

Driver

and

Front

Passenger

As a supplemental restraint system
(SRS), airbag system is a supplement
to seat belts. It can provide extra
protection for heads and chests of
the driver and passenger and reduce
casualties in severe frontal crashes

The airbag system cannot take the place
of seat belts and is only a part of the
whole passive safety protection system
of the car. Note that the airbag system
has the best protection performance
only when working together with
fastened seat belts. For the safety of
yourself and your family, please pay
sp

ecial attention to the ―Tips‖ and

―Notice‖ in this section.

● Please keep the seat belt
fastened in driving.
● Please keep sitting in correct
posture so that the protection
effect of the seat belt and airbag
system can be taken into full play.
● Children shall be seated in rear

seats.

● Do not dismount parts of the

airbag without permission.

System Components

SRS airbag consists of the following
components and their positions are
shown in the figure below:
1. SRS warning light
2. Front passenger airbag assembly
(airbag and air charging system)
3. Airbag electronic control unit (ECU)
4. Driver’s airbag assembly (airbag and
air charging system)
5. Impact sensor
6. Safety belt warning sensor (optional)

Airbag ECU consists of a safety sensor
and an airbag sensor.
