a dormant state. At this time, press
the microswitch on the driver's door
handle (See P54 ) to activate the low-
voltage battery. After the vehicle is
unlocked, it can be used normally.
Wake-up by jump starting
●
When the vehicle cannot be woken
up and unlocked by the driver's door
microswitch, use the mechanical key
to open the door. Then, use a 12V
power supply to start the vehicle by
two specially designed cables for the
jump start. In this case, the low-voltage
battery SOC is low. The instrument
cluster may display "The low-voltage
battery SOC is low, and the vehicle
is going to be powered o󽗈", and the
vehicle will become dormant again.
Start the vehicle immediately and keep
it started for over 15 min to ensure
that the low-voltage battery is fully
charged.
●
The jump start can only be carried
out through the special interface of
the under-hood PDB. The connection
terminals for the jump start in the
under-hood PDB are shown in the
󽗉gure.

Negative pole ②
●
If the vehicle cannot be woken up
and started by the above steps, it
is recommended to contact a BYD
authorized dealer or service provider
immediately.
WARNING
●
Do not connect the vehicle
with other vehicles for a jump
start before it is powered
on. Otherwise, the low-voltage
battery may be damaged.
●
If the low-voltage battery has low
SOC or fails to function normally,
a jump start may be required.
Please carefully read and strictly
follow the jump start instructions.
●
The low-voltage battery contains
an intelligent control module.
Do not disassemble or damage
this battery without permission,
except in an emergency.
●
Disconnect the negative terminal
of the low-voltage battery before
performing parts replacement and
vehicle repairs.
CAUTION
●
It is recommended that a jump
start be completed under the
guidance of professionals, as the
space for operating the under-
hood PDB is limited and potential
circuit-based risks may occur.
●
Do not clean the low-voltage
battery with liquid to prevent
ingress.
Usage Guidelines
Break-in Period
