Seat Belts
Seat Belt Overview
Studies have shown that proper use
of seat belts can signi󽗉cantly reduce
casualties in emergency braking, sudden
steering or collisions. Please read the
following information carefully and
observe it strictly.
WARNING
●Always have the seat belts
fastened while the vehicle is in
motion.
●Before driving, make sure all
occupants are properly buckled
up to prevent serious injury or
death in emergency braking or in
a collision.
●The seat belts are designed
primarily for adults and are not
intended for children. Make sure
to choose an appropriate child
restraint system according to your
child's age and size (see "Child
Restraint Systems").
●If a seat belt is damaged
or malfunctions, immediately
contact a BYD authorised
dealer or service provider
for con󽗉rmation and handling.
Until then, do not use the
corresponding seat.
●BYD has highly emphasised that all
occupants should always fasten their
seat belts while in the vehicle. Failure
to do so increases the risk of injury in
case of an accident.
●It is recommended that children be
seated in rear seats and always
use seat belts and suitable child
restraints. In emergency braking or
collision, unprotected children may be
seriously injured and their lives may
be endangered. Likewise, do not allow
children to ride on someone's lap. This
will render the children not adequately
protected.
Emergency Locking Retractor (ELR)
●When the driver turns sharply, brakes
suddenly, when there is a collision,
or when the occupant leans forward
too quickly, the seat belt automatically
locks to e󽗈ectively restrain and protect
the occupant.
●When the vehicle travels smoothly,
seat belts are pulled out and retracted
as the occupants move slowly and
smoothly, allowing the occupants to
move freely.
●If the seat belt locks due to sudden
retraction, pull on the seat belt
webbing to create retractable slack in
order to pull out the seat belt.
Pretensioner and Force Limiter
Function*
When a severe front collision occurs
and the triggering conditions of the
pretensioner are met, the pretensioner
quickly retracts part of the seat belt and
locks it to improve the protection of the
occupant. The force limiter limits the
seat-belt restraint force to the occupant's
body to a certain extent so as to avoid
injury to the occupant due to an excessive
restraint force.
Using Seat Belts
1. Adjust the seat position and seatback
angle (see Adjusting Front Seats).
2. Adjust the position of the three-point
seat belt.
12

●Keep the correct sitting posture and
pull out the shoulder belt diagonally
across the entire shoulder without
contacting the neck or falling from the
shoulder. Position the lap belt as low
as possible around the hip.
3. Insert the latch into the buckle until it
clicks, and then pull it back to make
sure it is 󽗉rmly locked. Do not fasten
the belt with any part of the strap
twisted.
4. Adjust the height of the (front)
seat belts for optimum comfort and
protection.
① Press the adjuster release button.
② Move the adjuster up or down to the
intended position. Release the button to
lock the adjuster.
5. Pull the belt 󽗉rmly to check that the
adjuster is locked.
WARNING
●The shoulder belt should cross
the centre of the shoulder. The
seat belt should be far from the
neck and not liable to slip from
the shoulder, otherwise it cannot
function well in the event of
emergency braking or accident,
and may even cause severe injury.
●The lap belt should be positioned
as low as possible around the hips
to avoid serious injury due to the
intense lap belt forces against the
abdomen in an accident.
●The seat belt should be 󽗉tted tight
to the body for better protection.
6. Unlock the seat belt.
●Press the red unlock button on the
buckle. The latch plate pops out, and
the seat belt automatically retracts. If
the seat belt does not retract smoothly
and automatically, pull it out and
check whether it is twisted.

SAFETY

REMINDER
●The method of wearing a rear
seat belt is the same as that
for a front seat belt. For normal
functioning of the rear seat belt,
please ensure that its latch is
inserted into the corresponding
buckle during use. The driver
should remind passengers to wear
seat belts properly.
●The driver should ensure that all
occupants are wearing seat belts
before driving the vehicle.
WARNING
●Each seat belt should be used by
one occupant only. Do not share
a seat belt with another occupant,
not even with a child.
●Avoid travelling with the seatback
leaning too far back. The seat belt
protection performs best when
the seatback is upright.
●Make sure that no seat belt
or itsspring bolt/buckle becomes
pressed by the door; otherwise
the seat belt may be damaged.
●Check the seat belts regularly
for cuts, wear, looseness, and
other abnormalities. If any
problem is found, contact a
BYD authorised dealer or service
provider for con󽗉rmation and
WARNING
handling. Until then, do not use
the corresponding seat.
●Do not remove, disassemble or
modify the seat belts without
permission.
●After an accident, have the seat
belts checked at a BYD authorised
dealer or service provider. If the
preloading function is activated,
the seat belt must be replaced.
●In the event of a serious
accident, even if there is no
apparent damage, the seat belt
should be replaced along with
the seat assembly. The airbag
system should also be thoroughly
inspected.
●Use an approved model whenever
you replace the seat belt.
●Pregnant women should also
fasten their seat belt properly.
Particularly, be sure to position
the lap belt as low across the
hip as possible to prevent serious
injury.
●Do not insert foreign objects such
as coins and clips into the buckle
as they prevent proper connection
between the latch and buckle.
Seat Belt Reminder
If the driver, front passenger or rear
passenger* has not buckled up after the
vehicle is started, the alarm system goes
o󽗈 and continues until the corresponding
seat belt is properly fastened.
●Unfastened seat belt indicator
●When any seat belt is not fastened,
the unfastened seat belt indicator
󽗊ashes.
14

●Display of unfastened belt's seat
●The indicator for the seat with
unfastened seat belt lights up.
●Seat belt reminder for the front
passenger
●If the driver or front passenger
does not wear the seat belt after
the vehicle is started, the seat
belt indicator and the indicator
associated with the corresponding
seat light up. If the seat belt remains
unfastened while driving, in addition
to the unfastened seat belt indicator,
an audible alarm is given to remind
the driver and occupants.
●Seat belt reminder for rear passengers*
●With the ignition switch on OK, if any
rear-row seat belt is not fastened,
the unfastened seat belt indicator
and the indicator associated with the
corresponding seat light up.
●When the drive speed is above 12
mph (20 km/h) and only rear seats
are loaded with occupant(s), who
have not buckled up, the seat belt
reminder indicator is on and an
audible alarm is given.
●When the driver, the front passenger,
and rear passengers* have buckled
up, the seat belt reminder indicator
and all indicators displayed for the
corresponding seats turn o󽗈.
WARNING
●In the event of abnormality
or function failure, contact
a BYD authorised dealer or
service provider. Do not use
the corresponding seat until the
functions return to normal.
●When driving, make sure all
occupants have their seat belts
properly fastened to prevent
serious injury or death in
WARNING
emergency braking or in a
collision.
Airbags
Airbags
●The airbag system is a part of
auxiliary restraint system and also
a supplement to seat belts. When
the vehicle is involved in a serious
collision and the airbag system meets
its deployment conditions, relevant
airbags will rapidly deploy and, along
with seat belts, provide additional
protection for heads and chests of
the driver and occupants, to reduce
likelihood of personal injury or even
death.
●Airbags are divided into front and
side types according to the type of
collision. The front airbags include
front passenger airbags, while the side
airbags include seat side airbags and
side curtain airbags.
●As an integral part of the vehicle's
passive safety protection system, the
airbag system does not replace seat
belts and must be used in combination
with seat belts to maximise protection.
Multi-collision Braking (MCB)
●In the event of an accident, the
automatic braking will be activated
when the driver airbag or the front
passenger airbag deploys.
●Speed reduction, along with the
intervention by additional driving
systems (ESC and ABS), assists the
vehicle to maintain stability and lane
position.
15
01
SAFETY

●Hazard warning light and brake light
would light up to warn oncoming
vehicles and aid to avoid secondary
collision.
●The brake is released after an accident
and brake lights are turned o󽗈 to
support emergency rescue or recovery
of the a󽗈ected vehicle.
●The driver can interrupt the multi-
collision braking at any time by
accelerating or braking.
WARNING
●Never seat a child in the front
passenger seat.
●Occupants must sit in a
proper position to maximise the
protection provided by seat belts
and the airbag system.
●Do not disassemble or assemble
airbag components without
authorisation.
●If the seatbacks get wet, the
side airbag system may not work
properly.
●Do not use seat covers, as they
restrict airbag deployment on the
corresponding side in an accident.
●Do not place anything between
the side airbag and the occupant.
●Do not apply excessive force to the
side of seats equipped with side
airbags.
●After a collision, even if the
airbag module did not deploy,
and the pretensioner did not
lock the seat belt, the airbag
computer may be encrypted in
order to protect occupants from
high-voltage danger. Contact a
BYD authorised dealer or service
provider for inspection.
Driver and Front
Passenger Airbags
This vehicle is equipped with driver
and front passenger airbags, when the
electronic control unit (ECU) of the airbag
system detects a moderate to severe front
impact during driving and the triggering
conditions are met, the airbags deploy.
Front airbag deployment
●In moderate to severe frontal crashes,
a sensor detects a sharp deceleration
and sends a signal to the ECU to trigger
the front airbags.
●When there is a frontal crash, the seat
belt secures the occupant's lower body
and torso in place. The airbag cushions
and protects the occupant's head and
chest.
●When the severity of the impact
does not reach the airbag deployment
threshold, seat belts provide the main
protection while airbags assist little to
the protection.
●The front airbag de󽗊ates immediately
after in󽗊ation, without a󽗈ecting the
driver's vision and ability to operate
the steering wheel or other controls.
●The airbag deploys quickly to protect
the occupants when reaching the
triggering condition.
●A loud noise will be heard when the
airbag deploys. It will not cause injury,
16

but it may cause temporary tinnitus or
deafness.
●A cloud of dust from the airbag surface
may come o󽗈 when the airbag deploys.
Although such powder is non-toxic,
individuals with respiratory problem
might experience some temporary
discomfort.
●The front passenger airbag is
controlled by the passenger airbag
(PAB) switch. See "PAB Switch*" for
details.
Seat Side Airbags*
If the vehicle is equipped with seat side
airbags (mounted on the outside of the
seatback, marked with "AIRBAG" at both
sides), when a moderate to severe side
impact is detected during vehicle travel
and the triggering conditions are met,
the side airbag deploys to protect the
occupant's chest to minimise the injury.
Front passenger side airbags
Rear passenger side airbags
Seat side airbags starting process
●Generally, only the airbag on the
impacted side deploys in the event of
a side impact.
●If the impact occurs on the passenger
side, the airbag on the passenger side
deploys even if there is no passenger in
the seat.
●For optimal side airbag protection,
occupants must have their seat belts
fastened and sit upright against the
seatback.
In a vehicle equipped with seat side
airbags:
●Prevent the seatbacks from getting
wet. If the seatbacks get wet from rain
or splashes, the side airbag system
may not work properly.
●Do not cover or replace seatback
covers on you own. Unsuitable
seatback covers may prevent airbag
deployment in a collision.
Front far side airbag:
●The vehicle you purchased is equipped
with a front far side airbag (installed in
the inner edge of the driver's seatback
and marked with "AIRBAG", as shown
in the illustration).
17
01
SAFETY

●When a moderate to severe front or
side impact is detected during vehicle
travel and the triggering conditions are
met, the far side airbag deploys to
protect the heads and shoulders of the
driver and the front passenger.
●If the impact occurs on the front
passenger side, the far side airbag
deploys even if there is no passenger
in the seat.
●For optimum protection from the far
side airbag, the driver must buckle up
and sit upright against the seatback.
Side Curtain Airbags*
If the vehicle is equipped with seat side
airbags (mounted on the outside of the
seatback, marked with "AIRBAG" at A, B
and C pillars), when a moderate to severe
side impact is detected during vehicle
travel and the triggering conditions are
met, the side airbag deploys to protect
the head of the occupant in a collision.
●Generally, only the airbag on the
impacted side deploys in the event of
a side impact.
●For optimum curtain airbag protection,
the occupant must have their seat belt
fastened and sit upright against the
seatback.
Airbag Triggering
Conditions and
Precautions
Airbag Triggering Conditions
●Airbag triggering conditions: In the
event of a vehicle collision, whether an
airbag will be triggered is decided by
factors such as the amount of collision
energy, accident type, collision angle,
obstacles, and vehicle speed. The
airbag system may be triggered in
special collisions.
●The airbag system does not always
work in any accident, and generally it
will not be triggered in the event of
a minor frontal collision, rear collision
or rollover. In this case, the driver
and passengers are protected by their
properly fastened seat belts.
●Determinants of airbag system
triggering: Decision is made by
comparing the deceleration curve,
generated in the collision and obtained
by the Electronic Control Unit(ECU )
and the set value. If signals, such as
the deceleration curve generated and
measured in the collision, are lower
than the respective reference values
preset in the ECU, the airbag system
will not be triggered even if the vehicle
may have been seriously deformed in
the accident.
●The ECU of the BYD airbag system
has been set up with considerations of
common misuse and road conditions.
18

However, due to the increasing
changes in causes and forms of vehicle
collisions, for your safety, please
strictly follow this user manual, use the
vehicle correctly, and avoid its misuse.
Otherwise, there is no guarantee that
the airbags will achieve their expected
e󽗈ect.
Cases Where Airbags May Be Deployed
The vehicle's nose hits the ground when
crossing a deep groove.
The vehicle hits a bump or curbstone.
The vehicle's nose hits the ground when
going down a steep slope.
One side of the vehicle is hit by another
vehicle.
Cases When Airbags May Not Be
Deployed
The vehicle hits a concrete column, tree,
or other slim objects.
The vehicle goes under a truck or another
large vehicle.
