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

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

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
