BYD SEAL 2023 - Usage Precautions

between these modes automatically,
having no e󽗈ec
t on your use of the
vehicle.
●
To avoid low-voltage battery feed,
the smart charging function will be
actively triggered if conditions (hood
closed, ignition "OFF", high-voltage
battery discharging allowed, and low-
voltage battery level lower than the
design value) are met.
●
When the smart charging function
is triggered, the low-voltage battery
is charged through the high-voltage
battery. Therefore, it is normal that the
SOC or the pure-electric driving range
displayed on the cluster decreases,
when the vehicle is started after being
idle.
●
If "smart charging" fails, the low-
voltage battery may cut o󽗈 the
vehicle's power supply. If you 󽗉nd
before use that the vehicle is not
powered, try to activate the low-
voltage battery by pressing the driver
door microswitch continuously, and
immediately power on the vehicle to
charge the low-voltage battery. It is
recommended to charge it for more
than 1 hour.
CAUTION
●
The s
tarter iron battery contains
relays. Thus it is normal to hear a
"click" sound when the battery is
running.
●
The starter iron battery shall
be charged with professional
charging tools, and shall not be
removed for recharging without
permission.
●
Do not jump-start the vehicle with
another fuel vehicle, as this may
damage the starter iron battery.
●
The starter iron battery is a
battery on low-pressure platform
CAUTION
that is di󽗈er
ent from an ordinary
lead-acid battery. Please read the
instructions for use in this manual
in detail.
●
The starter iron battery has
a built-in power manager. Do
not disassemble or repair the
battery without permission to
avoid damaging the battery or
causing personal injury.
●
The starter iron battery needs to
communicate with the vehicle for
normal use, so it is important to
connect its connector and wiring
harness correctly.
Usage Precautions
Br
eak-in Period
●
If the powertrain is hard to start or
frequently stops turning, inspect the
vehicle immediately.
●
If the powertrain makes any abnormal
sounds, stop the vehicle for inspection.
●
If the powertrain has severe coolant
and oil leakage, stop the vehicle for
inspection.
●
The powertrain needs break-in. It is
recommended that this be done within
the 󽗉rst 2,000 km in economic mode
by smoothly driving, instead of high-
speed driving. The following practices
can e󽗈ectively prolong vehicle service
life:
●
Avoid 󽗊ooring the accelerator pedal
when starting and driving the
vehicle.
●
Do not maintain a high or low speed
for too long.
