Usage Precautions - BYD SEAL 2023 Owner's Manual

between these modes automatically,
having no effect on your use of the
vehicle.
To avoid low-voltage battery feed,
●
the smart charging function will be
actively triggered if conditions (bonnet
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 off the vehicle's power
supply. If you find before use that
the vehicle is not powered, try to
activate the low-voltage battery by
pressing the driver's door microswitch
continuously, and immediately power
on the vehicle to charge the low-
voltage battery. It is recommended to
charge it for more than one hour.
CAUTION
The low-voltage battery contains
●
relays. Thus, it is normal that relay
operating sounds may be emitted
from the battery.
The low-voltage 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 low-voltage battery.
The low-voltage battery is a
●
battery on low-voltage platform
that is different from an ordinary
96
CAUTION
lead-acid battery. Please read the
instructions for use in this manual
in detail.
The low-voltage 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 low-voltage battery needs to
●
communicate with the vehicle for
normal use, so it is important to
connect its connector and wiring
harness correctly.

Usage Precautions

Break-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. This
●
should preferably be done within
the first 1,243 miles (2,000 km)
in economic mode. Steady driving
instead of high-speed driving is
recommended. The following practices
effectively prolong vehicle service life:
Avoid flooring the accelerator pedal
●
when starting and driving the
vehicle.
Do not maintain a high or low speed
●
for too long.
Avoid speeding.
