35 km/h, the system automatically
switches between low and high
beams based on the current driving
environment.
Precautions
• The HMA system is an auxiliary
light control function. While it is
recommended to use the system at
high vehicle speeds, the system cannot
completely replace the driver. The
driver must observe road regulations
and actively switch between high and
low beams according to road condition
changes at all times.
•
When the vehicle is in a high dynamic
state, for example when the ABS or
ESC is activated, beam switching is
suppressed.
• HMA system exits when fog light and
turn signal are turned on, wipers are
set to high-speed mode, the vehicle
is backing up, light switch is not on
"Auto", and the ambient light is too
strong.
• Even when HMA is working, the driver
must respond to possible situations
where the HMA is triggered in error
or fails to work due to unavoidable
environmental factors and conditions.
Typical situations are:
•The driver's stick operation to switch
to the high beam is prioritized.
•The weather, such as fog, rain
or snow, is extremely terrible for
driving.
•There are tra󽗋c participants with
poor lighting (such as pedestrians
and bicycles), railways or waterways
nearby, or wild animals on the roads.
•There are highly re󽗊ective objects
around (e.g., tra󽗋c signs on
highways, water re󽗊ection on the
road surface, etc.).
•The front windshield is dirty, covered
in mist, or blocked by stickers or
decorations.
• In case there is a collision or the
sensor has been reassembled, it
is recommended to go to a BYD
authorized dealer or service provider
for sensor calibration so as to avoid
a󽗈ecting system performance.
WARNING
• HMA only serves as a driving
assistance function, so the driver
must be fully responsible for
driving safety.
• In󽗊uence of weather, road
conditions, and other factors may
cause HMA to fail.
• Use HMA based on your needs,
tra󽗋c, and road conditions.
Lane Departure Assist
(LDA)*
Lane Departure Warning (LDW)*
The lane departure warning (LDW) system
detects the lane lines ahead through a
multifunctional video controller. When
the vehicle speed is 60 - 150 km/h and
the driver unintentionally drifts out of
the lane, the LDW system will warn the
driver by steering wheel vibration, voice
and instrument cluster display.
Lane Departure Prevention (LDP)*
• The lane departure prevention (LDP)
system identi󽗉es lane lines ahead
through a multifunctional video
controller. If the driver unknowingly
departs from the lane at a vehicle
speed between 60 km/h and 150
km/h such that the vehicle is about
to roll over lane lines, the system,
when activated, slightly turns the
steering wheel by providing reverse
torque through the electronic power
steering (EPS) system to prevent lane
departure.
