Status Description
●
HMA standby:
●
HMA When the function is enabled
but not activated yet, the icon is
displayed on the instrument cluster.
●
HMA activated:
●
After being enabled, HMA is activated
when the light switch is in Auto,
necessary lighting conditions are
met, and the vehicle speed is above
35km/h(22mph). At this time,
is
displayed on the cluster.
●
HMA failure:
●
When HMA fails, is displayed on
the cluster.
How to Use
●
To enable or disable HMA, go to
→ ADAS → Driver Assistance from
the touchscreen. When the vehicle
is started, the system defaults to
previous settings.
●
With the function enabled, when you
set the light switch to the auto lights
position, the light meets conditions
and vehicle speed exceeds 35km/
h(22mph), 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's
judgment. The driver must observe
road regulations and actively switch
between high and low beams
according to road condition changes at
all times.
●
Beam switching is suppressed if the
vehicle is in a high dynamic state, for
example when ABS or ESC is activated.
●
HMA is disabled when the ambient
light is too strong, or when the driver
turns on fog lights or turn signals, sets
the wipers to high speed, reverses the
vehicle, or turns the light switch to a
non-Auto position.
●
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 prioritised.
●
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
motorways, water re󽗊ection on the
road surface, etc.).
●
The front windscreen 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
authorised dealer or service provider
for sensor calibration so as to avoid
a󽗈ecting system performance.
WARNING
●
HMA serves as a driver assistance
function only, so the driver must
