BYD SEAL Overview
As a pure electric passenger vehicle, BYD SEAL is an environmentally friendly product. The
integration of its load-bearing body with the high-voltage battery pack fully ensures the
safety of the battery and the entire vehicle.
The vehicle is driven by electric motors across various working conditions, and therefore
has zero emissions. Being purely electric, the vehicle features very low noise inside and
outside, providing an exceptional driving and riding experience unmatched by any fuel
vehicle.
The safety of the high-voltage system is a priority in the vehicle design so that the driver
and passengers are protected in case of a collision.
The battery management unit continually monitors the high-voltage battery and adjusts its
output based on the voltage, current, and other performance indicators of each battery cell,
preventing issues a󽗈ecting battery performance such as over-charging, over-discharging
and overheating. This ensures that the batteries work under ideal conditions at all times.

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.
CAUTION
●Always have the seat belts
fastened while the vehicle is in
motion.
●Before driving, make sure all
occupants have their seat belts
properly fastened. In emergency
braking or collision, passengers
are more likely to be seriously
injured and their lives may be
endangered.
●The seat belts are designed
primarily for adults and are not
intended for children. Make sure
to choose an appropriate child
restraint system (CRS) according
to your child's age and size (see
"Child Restraint System (CRS)").
●If a seat belt is damaged or
malfunctions, contact a BYD
authorized dealer or service
provider for con󽗉rmation and
handling. Until then, do not use
the corresponding seat.
●BYD has highly emphasized 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 a suitable CRS.
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)
Function
●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.
14

●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 center 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 traveling 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
its spring 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 authorized 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 authorized
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 Reminders
If any occupant has not buckled up
after the vehicle is started, visual and
audible alarm go o󽗈 and continue until
the corresponding seat belt is properly
fastened.
●Seat belt reminder indicator
●This indicator 󽗊ashes if any seat's
belt is not fastened.
●Display of unfastened belt's seat
16

●The indicator for the seat with
unfastened seat belt lights up.
●Seat belt reminder for front passenger
●If the driver or front passenger
has not buckled up after the
ignition is switched on, the seat belt
reminder indicator and the indicator
associated with the corresponding
seat light up. If the seat belt remains
unfastened while driving, in addition
to the reminder indicator, an audible
alarm is given to remind the driver
and the occupant.
●Seat belt reminder for rear passengers*
●With the ignition on, if any rear-row
seat belt is not fastened, the seat belt
reminder indicator and the indicator
associated with the corresponding
seat light up. While the vehicle is
in motion, when only rear seats are
loaded with occupant(s), who have
not buckled up, only the seat belt
reminder indicator is on and no
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
●If the above functions are
abnormal or fail, contact a
BYD authorized dealer or service
provider.
●Make sure all occupants have their
seat belts properly fastened when
driving, or in emergency braking
or collision, passengers are more
likely to be seriously injured and
their lives may be endangered.
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 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 occupant 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 maximize 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
intervention by additional driving
systems (ESC and ABS), assists the
vehicle to maintain stability and lane
position.
●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.
17
01
SAFETY

●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 maximize the
protection provided by seat belts
and the airbag system.
●Do not disassemble or assemble
airbag components without
authorization.
●If the seatbacks get wet from
rain or splashes, 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 authorized dealer or service
provider for inspection.
Driver and Front
Passenger Airbags
If your 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 enough
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.
●Airbags can in󽗊ate rapidly when
triggering conditions are satis󽗉ed to
further protect drivers and occupants
in an accident.
●A loud noise will be heard when the
airbag deploys. It will not cause injury,
but it may cause tinnitus or temporary
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.
18

●The front passenger airbag is
controlled by the passenger airbag
switch. For details, see "Passenger
Airbag (PAB) Switch*".
Seat Side Airbags*
If the vehicle is equipped with seat side
airbags (mounted on the outside of seat
back, 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.
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.
Front far side airbag:
●The vehicle is equipped with front
far side airbags for the front seats
(installed in the inner side edge of the
driver seat and marked with "AIRBAG",
as shown in the illustration).
●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.
